The Pipe Bursting Process Explained

Various pipe replacement methods are now adapted by pipe repair contractors. One such method is pipe bursting. Yes, you read that right, the pipes are actually busted to allow repair. This isn’t your average pipe replacement method in which pipes are dug out and renewed. It’s a unique method that many people don’t understand but are genuinely curious with. Here are the steps of pipe bursting to help you understand how the operation goes.


Step 1. Surveying the structure of the pipes

All pipe repair contractors know the importance of knowing the pipeline they’re replacing. They will be able to strategically plan the operation if they already know which pipes to bursts. Contractors should also know which is the best area for inserting the tools and supplies. Modern pipe repair makes use of cameras to check the pipeline for obstructions. These blockage can infer against the pipe bursting which is why removing it is important. Removing the obstructions happens before the pipe bursting procedure starts.

Step 2. Removing any blockage

Breaking the old pipes requires the use of a bursting. It’s optimal if the bursting head doesn’t hit any blockade in the pipeline. Cleaning the pipes can help make the bursting procedure smoother and faster. A water jet is  used for removing stubborn clogs and other debris in the sewer pipes. Augers are another tool for removing various blockage — especially plant roots.

Step 3. Creating a dig site

The bursting head and new pipe is inserted into this dig site. But first, a dig site or access point must be created first. Two dig sites are needed for a pipe bursting method to work. One of the access point is where the bursting head and pipes are inserted. The other dig site is where the winch machine is placed. This winch machine will be used to pull the bursting head and pipe. The contractors already knows where to find the optimal area to make an access point. This is possible thanks to the pipe survey earlier.

Step 4. Inserting the equipment and pipe

After the dig site is created, the bursting tool and the pipes are slowly inserted into the access point. The bursting head is able to pulled into the pipeline because of the cable attached to it. This cable comes from a winch machine on the other access point.

Step 5. Breaking the pipes and inserting the pipe

The bursting procedure will start after the necessary preparations are done and the equipment is positioned. The winch machine pulls the bursting head with great pressure. This breaks the old and crumbling pipeline. The new pipes are also pulled as the bursting head is hauled by the pulling machine. Take note that this is just one of the many bursting methods. Don’t be baffled when your contractor uses other bursting equipment besides a bursting head. Other pipe bursting solutions use hammers instead of bursting heads to break pipes. A few final corrections and inspections are done and then the bursting procedure is concluded.
