TRIC - Model X30 - Pipe Bursting System - User Guide

The heart of each TRIC pipe-bursting system is essentially a cable-pulling device. Cable, or wire rope, has been an integral part of the TRIC method since the company introduced trenchless sewer lateral replacement in 1997. Laterals, or residential sewers, are often constructed with bends (directional changes) between the building foundation and the property line or public sewer main (see Figure 1). A cable is the most efficient way to negotiate these bends. It is quite common to pull through one or two bends in a lateral job, sometimes three or more. It is also possible to be stuck at any given point on an unknown obstacle, or because the pull has not been set up advantageously. See the next section on Bursting Preparation for logistical advice on some of the more typical job scenarios.
