JOB RELATED, PR100
Stay Cool And Stay Alive
If you work outdoors, summer is one of your busiest times of the year because it’s typically the driest season and offers the most hours of daylight. But the sun providing all that productive daylight can be the biggest jobsite hazard you face all year. Excessive heat can bring down anyone who doesn’t take the necessary precautions.Planning Ahead For WinterWinterizing your equipment is a small investment of your time that is guaranteed to pay big dividends. Your operator’s manual provides details on proper care during winter, but here are five essential steps you should take. Simco EnterprisesThe city of Groves, Texas, had a big problem on its hands. A 665-foot section of underground truss pipe (plastic pipe with a concrete-filled, hollow wall) was in need of replacement. IPBA Pipe Bursting Guidelines (PDF) Before you begin any pipe replacement job, be sure you've read and understood Guideline Specification for the Replacement of Mainline Sewer Pipes By Pipe Bursting, a very thorough and helpful set of guidelines from the International Pipe Bursting Association (IPBA). Trenchless Technology Center's Pipe Bursting Guidelines by ttc.latech.edu Prepared by the Trenchless Technology Center for the U.S. Army Corps of Engineers, Guidelines for Pipe Bursting is a technical report designed to help everyone involved in pipeline renewal/rehabilitation projects understand the capabilities of different types of pipe bursting systems. Case studies help illustrate the many important considerations of a typical pipe bursting jobsite. Keeping Your Fleet's Hydraulic Systems Running ProperlyIf your machine's hydraulic system isn't working, neither are you. Here are some common causes of hydraulic system breakdown and steps you can take to avoid them. Trenchless Technology Solving Age-Old Infrastructure DilemmaRoughly 1.5 million miles of buried water line exist in the United States. About one—third of these pipes are in need of replacement or repair right now, and many experts believe that by 2020 nearly half of these lines will need some type of renovation or extension.
stopimg title="keepCool_img1" style="padding-right: 20px;" align="left" style="BORDER-BOTTOM: 0px solid; BORDER-LEFT: 0px solid; WIDTH: 260px; PADDING-RIGHT: 10px; HEIGHT: 195px; BORDER-TOP: 0px solid; align: left" alt="keepCool_img1" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/1_KeepCool_260x195(1).jpg" border="0" />Catastrophic tornadoes and floods have grabbed recent headlines, but each year one weather phenomenon kills more people than tornadoes, floods, hurricanes, and lightning combined: heat.
According to the National Oceanic and Atmospheric Administration (NOAA), an average of more than 1,500 people in the U.S. die each year from excessive heat—yet it is the most preventable of weather-related deaths.
If you work in construction, summer is one of your busiest times of the year because it’s typically the driest season and offers the most hours of daylight. But the sun providing all that productive daylight can be the biggest jobsite hazard you face all year. No matter how tough you are or how used to the heat you think you are, excessive heat can bring down anyone who doesn’t take the necessary precautions.
The following information applies to anyone who is employed in an outdoor profession—construction workers in particular—but also applies to those who work in hot factories and anyone who spends time outdoors exercising, gardening, or laboring in any capacity during the summer months. (This is general information. More specific information can be found in the sources cited below.)
Know Your Chemistry
Our bodies dissipate heat by varying the rate and depth of blood circulation, and by expelling water through the skin and sweat glands. When we reach the danger zone, when our blood is heated above 98.6 degrees, we begin to pant—we’re literally “working like a dog.”
Sweating alone does little to cool the body, unless the sweat is removed by evaporation. But high relative humidity inhibits evaporation. When you’re checking the forecast for tomorrow, pay close attention to the heat index: the combination of relative humidity and air temperature. For example, if the air temperature is 96° F and the relative humidity is 65 percent, the heat index is 121° F. This is the heat your body really feels.
Heat disorders involve a reduction or collapse of our bodies’ ability to shed heat by circulatory changes and sweating, or a chemical (salt) imbalance caused by too much sweating. When heat gain exceeds the level the body can remove, or when the body cannot compensate for fluids and salt lost through perspiration, the temperature of the body's inner core begins to rise, bringing on various degrees of heat-related illnesses.
stopimg title="keepCool_img2" style="padding-left: 20px;" align="right" style="BORDER-BOTTOM: 0px solid; BORDER-LEFT: 0px solid; WIDTH: 260px; PADDING-RIGHT: 10px; HEIGHT: 195px; BORDER-TOP: 0px solid; align: right" alt="keepCool_img2" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/2_KeepCool_260x195.jpg" border="0" />Ranking Heat Disorders
The severity of heat disorders is relative to a person’s age, weight, fitness, medical condition, and degree of acclimatization to the heat. For example, heat cramps in a 17-year-old may translate as heat exhaustion in someone who is 40, and heat stroke in a person over 60. Common heat disorders include:
- Sunburn. Along with being painful and irritating, sunburn can significantly retard the skin’s ability to shed excess heat. The best solution for sunburn is prevention, by applying sunscreen throughout the day.
- Heat cramps. Symptoms are painful spasms, usually in the muscles of the legs and abdomen, often preceded by profuse sweating.
- Heat rash. Also known as prickly heat, heat rash can occur in hot, humid environments where sweat is not easily removed from the surface of the skin by evaporation. Serious heat rash can be so uncomfortable that it inhibits sleep and impedes a worker’s performance.
- Heat exhaustion. Symptoms include heavy sweating, weakness, headache, fainting, vomiting, and skin that is cold, pale and clammy. It is possible to have a normal temperature with heat exhaustion.
- Heat stroke or sunstroke. This is the most serious health problem for workers in hot environments. Heat stroke occurs when sweating stops and the body can no longer rid itself of excess heat. Symptoms include an excessively high body temperature (106° F or higher); mental confusion or delirium; convulsions; hot, dry skin; strong and rapid pulse; and possible unconsciousness. Make no mistake: heat stroke can be fatal, and victims need immediate medical attention.
Prevention: The Best Solution
The number one method of avoiding heat disorders: avoiding heat. But for construction workers in the summer, this is simply not possible. So, here are some tips for staying cool and staying alive, beginning with the most obvious:
- Drink plenty of fluids. Your body needs water to keep cool. Drink water even if you don't feel thirsty. Proper hydration actually begins the day before a long, strenuous day in the sun. Before increasing your fluid consumption, consult a physician if you (1) have epilepsy or heart, kidney, or liver disease; (2) are on a fluid-restrictive diet; or (3) have a problem with fluid retention.
- Do not drink alcoholic beverages. Alcohol dehydrates your body. Enough said.
- Limit caffeine intake.
- Do not take salt tablets unless specified by a physician.
- Put less fuel on your inner fires. Foods that are heavy in protein increase metabolic heat production and also increase water loss.
- Dress as lightly as possible. You need protective clothing, of course, but consider light-colored fabrics, such as cotton, that breathe.
- When possible, take longer breaks than normal in a cool, shaded area. A rested worker is a more productive worker.
- Know the symptoms of heat illnesses. Use a buddy system to keep tabs on your fellow workers.
- Acclimate yourself to the heat. You can “get used to” the heat, to some degree. Workers, especially those who follow the advice above, can eventually develop some degree of tolerance. However, new employees and workers returning from an absence of two weeks or more should have a five-day period of acclimatization: 50 percent of the normal workload and time exposure the first day, gradually building up to 100 percent on the fifth day.
stopimg title="keepCool_img3" style="padding-left: 20px;" align="right" style="BORDER-BOTTOM: 0px solid; BORDER-LEFT: 0px solid; WIDTH: 260px; PADDING-LEFT: 10px; HEIGHT: 195px; BORDER-TOP: 0px solid; align: left" alt="keepCool_img3" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/3_KeepCool_260x195.jpg" border="0" />Supervisor Obligations
There are precautions every employer should take when temperatures are high and the job involves physical work.
- Understand the signs of heat stress and permit workers to interrupt their work if they are extremely uncomfortable.
- Provide training about the hazards leading to heat stress and how to prevent them.
- If possible, schedule the heaviest workload for the coolest part of the day: early morning or late evening, when the sun is less intense.
- Make sure your workers have easy access to cool water—a minimum of one quart of water per hour, per worker.
- Schedule frequent rest periods with water breaks in shaded or air- conditioned areas.
- Routinely check on workers who are at risk of heat stress due to protective clothing and high temperature. Pay close attention to those who are at risk because of age and physical condition (including obesity and diabetes).
When A Fellow Worker Is Ill From The Heat
- Call a supervisor for help. If the supervisor is not available, call 911.
- Have someone stay with the worker until help arrives.
- Move the worker to a cooler/shaded area.
- Remove outer clothing.
- Fan and mist the worker with water; apply ice (ice bags or ice towels).
- Provide cool drinking water, if the worker is able to drink.

stopimg title="19a" style="padding-right: 20px;" align="left" alt="19a" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/19astopimg4Take the time to winterize your equipment this year. A few minutes spent could save you time and money in the months to come. The amount of winter care your equipment needs depends both on the climate and how it is used. Check your service manual guidelines, and keep the following tips in mind:
1. Check coolant. Provide protection by using the recommended antifreeze/water mixture for the lowest temperature expected during operations.
2. Change the oil and filter before cold weather arrives. In addition, use lubricants recommended for low temperature applications.
3. Maintain the battery. Remove cables, clean cable ends and posts, and clean and tighten terminals on the cranking motor. And remember never to charge a frozen battery.
4. Check tire inflation. Tires inflated in a warm shop will be under-inflated when used in cold temperatures.
5. Give hydraulic components time to warm up before beginning work. If you’re running diesel equipment, be sure to idle the engine a few minutes before shutting down to properly lubricate internal components. Your local Ditch Witch® service technicians can help you make the most of your cold-weather equipment productivity, and can suggest winterizing techniques that are perfectly suited to your operation.
stopimg style="padding-right: 20px;" align="left" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/PR100_4.jpg" alt="PR100_4" title="PR100_4" />The city of Groves, Texas, had a big problem on its hands. A 665-foot section of underground truss pipe (plastic pipe with a concrete-filled, hollow wall) was in need of replacement.
The pipe was located on an easement, with an apartment complex to the right, and a subdivision to the left. Trenching for that much pipe would cause a major disruption in traffic, utilities and the peoples' lives in the adjoining neighborhoods.
A huge amount of time and money would be dedicated to rebuilding fences and driveways that were torn up during the process.
Traditionally, the Houston area used the pneumatic method for this type of project which could create lateral cracks in the surrounding utilities due to concussions generated by the process. The aforementioned 665-foot section of truss pipe was also located only three feet from a water line. The project team was concerned that the pneumatic method may cause water to leak from that line two or three months after the project was complete, thus taking them back to square one with the neighborhood disruption.
The city put the project out for bid, and Simco Enterprises won. Simco considered using its Ditch Witch horizontal directional drill, but it didn't fit that application. The recommended drill also lacked the tools necessary to accommodate different sizes of pipe in this section. Sales Manager Jason Collins and his team from Ditch Witch of Houston offered to deliver and demonstrate a pipe burster to Simco, with no obligation.
stopimg style="padding-left: 20px;" align="right" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/PR100_1.jpg" alt="PR100_1" title="PR100_1" />The demonstration led to the Ditch Witch organization's first sale of the PR100 pipe bursting system in the United States. The Ditch Witch PR100 pipe burster was first revealed at ICUEE in October 2009.
"We were impressed with the durability and strength of this product, along with the people supporting it," said Mike Suire, general manager of Simco Enterprises. "Underground utility installation can and does present an abundance of adversity. With 18 years' experience in trenchless pipe installation, the PR100 demonstrated the progress of this technology over the past two decades. By purchasing this new machine, Simco Enterprises intends to utilize its versatility and production efficiency while minimizing the disruption to the surrounding area and people."
Like most of the pipes in the U.S., this section of pipe had deteriorated over time. To find a solution for the present, the cities had to look to the past.
The story goes back to a time when cities began developing sanitary systems, and building the pipes and sewer treatment plants to support them. For example, the plants were designed to treat 35-million gallons of fluid per day. As the pipes deteriorated over time, they could still hold the standard amount of waste; however, after one good rain, the now-cracked pipes overflowed—due to inflow and infiltration, also known in the industry as I/I—and the plant must now process up to 100-million gallons of water and sewage. To solve the problem, the overburdened plant would open its gates and let the waste flow into bayous, rivers and lakes.
Naturally, the Environmental Protection Agency (EPA) became involved because of this highly unsanitary practice. They began fining the city each time the sewer overflowed. The city couldn't afford to keep paying fines, and the EPA couldn't allow the unsanitary measures taken by the plants to continue. The EPA and the city agreed on two things: the solution is in rebuilding the pipes, and the city couldn't afford to repair all of those pipes at once.
stopimg style="padding-right: 20px;" align="left" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/PR100_2.jpg" alt="PR100_2" title="PR100_2" />Fast forward to the 1990s. The city submits a plan to the EPA and both parties come to an agreement about how many feet per pipe can be replaced that year. The methodology is interesting. The city sends robotic cameras to determine which sections are in the worst shape by calculating the amount of grease or debris buildup. For example, if a pipe has eight-inch lines, but only two inches of sewer are flowing through it due to grease or debris buildup, it would be at the top of the list for replacement. Once the list is agreed upon, the city reviews the videos taken from the robotic cameras and decides whether the replacement method in each instance will be pipe bursting or other alternative methods.
In this instance, the 665-foot section needed pipe bursting, but the project held many challenges. The first obstacle to overcome was the potential disruption to utilities, driveways and fences. The PR100's trenchless method turns this into a non-issue. It does not affect the existing infrastructure while installing the replacement pipe.
The second obstacle was the potential damage caused by "hammering." Not a problem. The PR100's static system uses hydraulics that dramatically lessens the vibration to the ground and existing utilities, thus solving the hammering problem during the project and the potential fallout afterward.
In the past, cities in the Houston area had experienced problems with equipment not being able to burst the truss pipe or handle the job, so they had to open-cut the pipes which caused a major disruption. On this job they had the right equipment. Out of 100 tons of pulling force that the PR100 is capable of, it never exceeded 36 tons of pulling force and Simco was able to complete the 655-foot pull in just over two hours.
Perhaps the biggest concern was the truss's PVC pipe material itself. It stretches. Solution: The PR100 has three different cutting edges for different-sized pipes. Think of it in relation to a clock on the wall. It grips the pipe at 3:00, 9:00 and 12:00 in the front where it's narrow, so it stretches and cuts as it pulls in the new pipe.
stopimg style="padding-left: 20px;" align="right" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/PR100_3.jpg" alt="PR100_3" title="PR100_3" />Everyone likes a happy ending, and the City of Groves and its residents have one. Simco Enterprises has purchased a Ditch Witch PR100 pipe bursting system and the company is very happy with its performance, reliability and the support provided from Ditch Witch of Houston. Other cities and contractors are also strongly considering the PR100 due to these same characteristics. Sometimes we can learn from the past.

If your machine's hydraulic system isn't working, neither are you. Here are some common causes of hydraulic system breakdown and steps you can take to avoid them.
stopimg title="SK650_1" style="padding-right: 20px;" align="left" alt="SK650_1" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/SK650_1stopimg4Contamination
An estimated 75 percent of all hydraulic system failure is due to contamination, so change filters regularly. If filters become dirty too frequently, examine them. Metal shavings can indicate that a pump, motor, or other upstream component may be failing. Resin or sludge—type material usually means oxidation of the fluid, often caused by low fluid levels or damaged seals.
Use clean tools and equipment, and always thoroughly clean hydraulic components before you remove, repair, or reinstall them. When you disconnect a hydraulic line, cap the end to keep contamination out while you're servicing the system. When you put the system back together, always install a new filter.
stopimg title="SK650_2" style="padding-left: 20px;" align="right" alt="SK650_2" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/SK650_2stopimg4Low or Dirty Fluid
Low fluid levels can cause everything from sluggish cylinder operation to catastrophic pump cavitation, so check the fluid regularly (with the engine off and the fluid cool) and maintain the proper level. Always use the right fuel for your system.
Murky or cloudy fluid usually indicates water or air in the system. Water can come from condensation, and excess air can be a result of low fluid levels, a damaged seal, or a crack in a suction hose.
Other System Components
Sometimes the obvious causes of hydraulic system trouble get overlooked. Try these preliminary checks:stopimg title="SK650_3" style="padding-right: 20px;" align="left" alt="SK650_3" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/SK650_3stopimg4
- Check the hydraulic fluid level with the engine off and the fluid cool.
- With the engine stopped, check for leaks around seals, castings, and hydraulic connections.
- Check for kinks in hydraulic lines.
- Check for a plugged or damaged fluid cooler or fluid filter.
- Check the electrical connections to solenoid valves. The problem may not be hydraulic after all.
When in doubt, you can always find factory—trained technicians at your Ditch Witch dealership, professionals whose only business is keeping Ditch Witch equipment healthy.
stopimg title="1pipeburst_R3" style="padding-right: 20px;" align="left" alt="1pipeburst_R3" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/1pipeburst_R3stopimg4Roughly 1.5 million miles of buried water line exist in the United States. About one—third of these pipes are in need of replacement or repair right now, and many experts believe that by 2020 nearly half of these lines will need some type of renovation or extension.
In some parts of the country, replacing outdated water and sewer lines using traditional open—cut excavation methods is simply not an option. The village of Glen Ellyn, Illinois, is one such place.
Glen Ellyn is a beautiful community, with stately homes and revered, 100-year-old trees. But below the streets of this affluent town, located about 23 miles west of Chicago, it is not as beautiful. Like most communities across the country, Glen Ellyn has aging water and sewer lines that are straining—and often failing—to meet the water and sewer needs of today's larger populations. And, like most communities, Glen Ellyn doesn't want the replacement of this infrastructure to disrupt normal life any longer than it absolutely has to.
Fortunately, advancements in trenchless technology have made it possible to replace water and sewer lines faster and with far less impact on the landscape than ever before, as citizens in Glen Ellyn recently discovered.
An 800-foot storm drain deep beneath a residential street in Glen Ellyn was in need of replacement. After taking bids from several contractors, city officials awarded the job to Trench Rite, Inc., a construction company from nearby Elgin, Illinois, based in part on the company's intention to use trenchless technology—horizontal directional drilling (HDD) equipment and a relatively new technology: pipe bursting systems.
stopimg title="2pipeburst_R3" style="padding-left: 20px;" align="right" alt="2pipeburst_R3" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/2pipeburst_R3stopimg4For this job, a pipe bursting system was the preferred option because the storm drain ran below the sewer line. Trench Rite rented a Ditch Witch PR95 pipe bursting system from Ditch Witch Midwest of Carol Stream, Illinois. The first step was to build a launch pit for the pipe bursting unit and an exit pit on the other end of the installation. The launch pit was 18-feet below the ground—well below the sewer line and other infrastructure in the vicinity. To reinforce the pit walls, the contractors used solid-steel shoring.
The pipe bursting process begins by pushing a series of threaded, one-meter steel rods through the existing pipe. When the rod string reaches the exit pit, a cracking head is attached to the rod string and then pulled back to the launch pit. (There are cracking, cutting, and splitting heads, depending on the type of pipe being replaced.) Behind the cracking head is the replacement pipe, which takes the place of the old pipe as the cracking head breaks through it.
stopimg title="3pipeburst_R3" style="padding-right: 20px;" align="left" alt="3pipeburst_R3" src="/uploadedImages/Left_Nav/Press_Room/Job_Related_List/3pipeburst_R3stopimg4The pipe being replaced was ten-inch VCP (vitrified clay pipe). To expand the capacity of the drain, the VCP was replaced with 16-inch IPS polyethylene pipe. With 95 tons of available pullback force, the PR95 is capable of replacing clay, steel, or iron pipe with polyethylene pipe of greater diameter.
This was Trench Rite's first time to use Ditch Witch pipe bursting equipment, and the company was impressed by the unit's ability to do the job without affecting adjacent utilities and surface obstacles like trees and sidewalks. The Trench Rite crew was also surprised by the speed at which the PR95 replaced pipe. One 209-foot section required only two hours and 15 minutes, from the time contractors hooked up the cracking head and finished pulling the new pipe to the pit wall.
With the Ditch Witch PR95, Trench Rite was able to complete the job in a fraction of the time that traditional open—cut excavation would require, helping the village of Glen Ellyn avoid weeks of traffic problems and noise pollution.
The world's water and sewer infrastructure is deteriorating; American ingenuity, fortunately, is not. And Ditch Witch pipe bursting technology is one of the innovative and economical solutions we'll need to meet the monumental challenge of modernizing our subterranean highways.
