Pipe Jacking Procedure

Pipe Jacking consists of advancing pipe through the ground with thrust provided by hydraulic jacks and excavation of soil at the front of the pipe string either manually or mechanically. The process requires personnel entry into the pipe being jacked to excavate by hand. The hand excavation is usually accomplished inside a shield attached to the leading section of pipe. The shields are typically articulated which allows some degree of line and grade control. The purpose of the shield is to provide a safe working environment for the workers and allow the bore to stay open for the pipe to be jacked into place. Typically, pipe jacking is done with pipes 42 to 120 inches in diameter and Boz culverts 7' to 14'. Pipe jacking is typically used in soil types with low permeability and good standup time or in soils that have been dewatered or otherwise prestabilized by ground improvement methods such as grouting.
