Pipe Jacking Contractors

Pipe jacking is a trenchless method for installation of steel pipes and casings. Distances of 30 m (150 feet) or more and over 1,500 mm (60 inches) in diameter are common, although the method can be used for much longer and larger installations. The method is useful when installing pipe below sensitive areas. The majority of installations are horizontal, although the method can be used for vertical… More

Pipe jacking is a trenchless method for installation of steel pipes and casings. Distances of 30 m (150 feet) or more and over 1,500 mm (60 inches) in diameter are common, although the method can be used for much longer and larger installations. The method is useful when installing pipe below sensitive areas. The majority of installations are horizontal, although the method can be used for vertical installations. The method uses pneumatic percussive blows to drive the pipe through the ground. The leading edge of the pipe is usually open, and is typically closed only when smaller pipes are being installed. The shape allows a small overcut (to reduce friction between the pipe and soil and improve load conditions on the pipe), and directs the soil into the pipe interior instead of compacting it outside the pipe. These objectives are usually achieved by attaching a soil-cutting shoe or special bands to the pipe. Less
