Process of splitting or fracturing the host sewer main and forcing the fragments into the surrounding soil, for the purpose of inserting a new pipe of equal or larger diameter.

PIPE BURSTING


When the existing sewer is deteriorated badly, or needs to be upsized, pipe bursting is the rehabilitation option most often employed. This process uses pneumatic powered bursting heads to clear away the old pipe and make way for the new pipe. The bursting head is pulled through the old pipe by the constant tension applied to it from the specialized winch while the bursting head is cycling every few seconds performing percussions to the old pipe. This hammering effect “bursts” the old pipe, clearing the way for the new pipe, which is attached to the rear of the bursting head. While HDPR is the most common pipe used in pipe bursting, other materials such as PVC and ductile iron can be used.

Another type of pipe bursting CaJenn employs is called static pull pipe bursting. This method uses a cutting head arrayed with rolling cutters to split the old pipe, followed by an expander head pulling the replacement pipe. With static pull pipe bursting there are no percussions, and thus no hammer effect on the surrounding soils and structures. With either of these types of pipe bursting, the service connections are dug up and reconnected to the new pipe. If desired, CaJenn can pipe burst the service laterals as well.
