Trenchless Pipe Replacement Technology: Facts From Reliable Hydro Excavation
Trenchless Pipe Pulling Replacement Technologies
One day trenchless sewer repair. The option could be yours! A new pipe is pulled through the old pipe using hydraulic machinery, completely replacing the old/broken pipe. Can be used on pipes from 2” to 36” (has been used up to 48”). HDPE and MDPE are the most common replacement pipes used in this method. Cast iron, vitrified clay, and reinforced concrete pipes can also be used. Reliable Hydro Excavation Services, the Cleveland, OHTrenchless Pipe Replacement experts!
Hammerhead Technology pipe bursting head. A bursting head is attached to the replacement pipe and is pulled through the old line. The bursting head breaks up the old pipe as it gets pulled through. The head is attached to a pulling cable that is drawn using a winch powered by hydraulics.
This method requires 2 access points. This method can be used to replace pipes with same size diameter or larger. Pipe is pulled through the old pipe.
Pipe Pulling Trenchless Technology
This technology requires two access points via a small, excavated entry trench to provide access to the host pipe, or to a manhole if the insertion will begin there. Also, a lubricant such as bentonite can be used to facilitate the slipping action required to insert the pipe. This repair always results in a smaller diameter pipe.
A polyethylene (Deformed & Reformed) or PVC alloy (Fold & Form) pipe, smaller than the original broken pipe is pulled through the existing pipeline using a winch. Pipe sizes of 3” to 30” can be repaired. Continuous lengths of 1500 feet in the smaller diameters and 800 feet in the larger diameters can be used. Once inserted, the pipe is heated using steam and air pressure, to let the material “relax”, which resets the material’s “memory” to the new size and shape of the pipe it is in. Thermoformed pipes usually leave a pronounced dimple at each lateral connection. Robotic equipment is used to reinstate these connections. Once installed, the thermoformed pipe will not return to its original size or shape after it has cooled, nor will it shrink in length. It will take on the shape and size of the original sewer pipe.
Special sleeves or short sections of CIPP are installed inside the pipe only in the area where the pipe needs to be rehabilitated. With the help of a sewer inspection camera for proper placement, the sleeve is sealed in pace with grout or glue.
This provides a more economical way to maintain sewer lines. Instead of replacing the whole pipe section, only the damaged section is repaired. Properly done, this can provide a huge cost saving.
Which Trenchless Sewer Repair Method Do I Choose?
For most residential repair jobs, CIPP or Pipe Bursting would be used. These methods generally cost more than conventional digging, but will minimize the destruction of the homeowner’s property. Municipal repairs are a lot more complicated and will require an evaluation by the city for each particular condition, considering the location of the pipe and the nature of the break.
From one city’s experience, CIPP is used when:
Sewer is deep underground;
There are abrupt changes in direction and/or grade;
Host sewer pipe is 8 inches or smaller;
Existing sewer laterals need to be retained – a robotic cutter makes holes in liner to connect to existing laterals. Comparatively, slip lining needs an excavation at each lateral connection.
