Important Steps in Trenchless Pipelining Technology


Trenchless technology is one of the most efficient and environmentally safe methods for installing pipelines. It is also quicker, cheaper, and causes less disruption than traditional digging techniques. Some trenchless technologies use a technique known as pipe bursting to install new pipelines. The following is a step-by-step guide on how to trenchless pipelines.

Pre-Installation Survey

This step involves careful planning regarding soil composition, depth of the trench, potential obstacles in the ground, and location of existing utilities that would have been identified from analysis performed before beginning work. It also entails underground obstacles mapped by workers on previous job sites, cabling/piping information from similar projects nearby, and engineering data from companies specializing in infrastructure development. If GPS coordinates are not available, a topographic survey is performed. Various equipment and methods are utilized to determine the installation’s location accurately in the survey.

The Excavation Stage

The next thing that will happen in the process is excavation. There are no obstructions on-site for laying down the pipelines at this level. The company has the right to remove anything on their property with or without notifying you. This depends on what is causing them problems in setting up pipelines in your area. If they do not have access to the pipeline, they may use this as an excuse for them not to pay out damages if something were to go wrong during construction.

Pipeline Installation

Pipes are then laid into position using specially designed machines that can lay pipes through trenches, under-sewers, and ground with no issues. The company will make sure that there are no problems setting up the pipelines using these machines. The pipe is installed through trenchless technologies such as pipe-jacking and HDD. In pipe-jacking, workers push the piping forward through the ground via pressure from above-ground pumps that supply water under high pressure into cable booms at intervals along the length of the piping. In HDD, a horizontal drill head drills horizontally underneath pipes already in place on top of a semi-firm surface, often concrete then turns 90 degrees and moves forward by pushing cables through the drill head. The newly-installed piping is then coupled via a coupling connection to pipes already in place.

The Cabling Step

Cables may need to be attached to the pipelines depending on their carrying through them. Once the cabling is done, any other work needed, like concrete protection, may also be added at this point. It depends on the type of work being done and if it requires another form of piping to keep everything safe while it works. Groups like plumbers or gas station workers know best when their materials will work best in having other equipment around. They have been trained for years on how certain types of pipes react when paired together, so they will know what to do during the trenchless pipelining.

Leveling and Backfilling

Once everything is in place, the Pipelining in San Diego company will level out land. This is to make sure it is not sinking or anything of that sort. They may also fix any damage or problems with the ground which may have been caused by them while digging to lay down pipelines, among other things. Once done, all materials used for this job are then picked up and backfilled. This means they cover up the area where they have worked using dirt from undisturbed areas on your property or undisturbed areas from nearby fields. Everything must look exactly as before so that no one can tell work has even been done.

A water supply line is one of the most common infrastructural elements that require excavation to complete installation. Trenchless technologies, including pipe-jacking and horizontal directional drilling, can install piping while minimizing disruptions and excavations.
