Static Pipe Bursting with NO-DIG Pipe
Advance Quicklock® bursting rods through the existing pipe with the hydraulically operated Grundoburst® until the rods reach the launching pit. A flexible guide rod in front helps navigate the existing line. Upon entry at the launch pit, the guide rod is removed and a bursting head, an expander and new NO-DIG vitrified clay jacking pipe are attached.
Pull the entire configuration back through the existing pipe. The bursting head and expander displace the fragmented existing pipe into the surrounding backfill while the new NO-DIG Pipe is pulled in. The pipe is launched one section at a time and assembled sections are held in compression at the rear by a pressure plate connected to a hydraulic cylinder pack. The cylinder pack both homes each pipe joint and holds all assembled pipe sections in compression as the expander is pulled forward.
