What are the differences between trench and trenchless technology methods for sewer rehabilitation construction in Kamloops?
Most of Kamloops is served by a sanitary sewer collection system, which is made up of over 500 kilometres of sewer pipes. That is a lot of pipe that can become broken or damaged, so to have an efficient method to replace or repair broken or damaged piping in Kamloops is essential because groundwater contamination is a serious environmental hazard. Sewer piping can become damaged due to settling or frozen soil, blocked due to grease build-up or foreign objects, corroded due to pipe deterioration, or root infiltrated due to tree or shrub roots. When a portion of sewer line needs to be accessed for pipe replacement or repair, the open cut method or the trenchless method can be used.
For sewer pipe rehabilitation construction, the open cut method uses a backhoe or small excavator to open the area surrounding the pipe. In some cases, the excavation may become deeper than 3 meters, so shoring may be required. There are different trenchless methods for this type of construction, but they all use two small access holes where the damaged pipe starts and ends. With the trenchless pipe bursting method, a hydraulic machine is placed in an access whole where the damaged pipe ends. This machine pulls a bursting head through the old sewer pipe’s path, breaking up the damaged pipe while pulling a new replacement pipe from an access whole where the damaged pipe begins, to where the damaged pipe ends. This is an ideal technique to use for the rehabilitation of ageing utility systems located in municipalities, because it involves very little disturbance on the nearby underground utilities.
The trenchless fold and form method is an effective sewer rehabilitation method that repairs existing underground sewer pipeline. The liner is heated, pulled into the damaged pipe, and reformed with steam and air.
There are many other trenchless technology methods, but this report will not covering them because they are used for new sewer piping construction. The trenchless slip lining is used for pipe rehabilitation, but will also not be covered because in this method, a new pipe is pulled into the damaged pipe, fitting close to the existing pipe, however, still causing quite a bit of inside pipe diameter difference, which isn’t good for sewage flow rates.
Nice abstract outline and nice picture. But I'm confused on what the picture is showing. Adding labels or something might help? And how are you applying your research to Kamloops?
ReplyDeletethe picture demonstrates relining of sewage pipes which is an alternate solution to pipe rehabilitation. this is often all that is required in the case of cracks or breaking joints, a sock is pulled through the pipe to fit the existing shape and seal the cracks. this is then cut for each individual service that is necessary to connect.
ReplyDeletebut i agree, a label could certainly help!
Thanks Jordan,
ReplyDeleteI agree that labels would help on the diagram too.
I am going to apply the research to Kamloops by finding the pricing for the two different technology methods in Kamloops... and using the different sewer piping that Kamloops has as examples. Do you think there is a better way I could link my research more to Kamloops?
Hi James,
ReplyDeleteThanks for the clarification on the fold and form method of trenchless technology.
I was wondering when using other trenchless methods, like pipe bursting, how do they connect the individual services to the newly installed pipe again?
