NO-DIG Pipe Installation
Static Pipe Bursting with Vitrified Clay Jacking Pipe
Step 1
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.
Step 2
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.
