Pipe Jacking Machine

DN type all-hydraulic computer controlling single cutter soil pressure balance pipe jacking machine

DN type all-hydraulic computer controlling single cutter soil pressure balance pipe jacking machine: To be used in soft soil,hard soil , strong weathered rock and all-terrence soil for pushing pipe and tunnelling with reliable structure and good construction achievement in large calibre pipe pusher. Requirement for backfil depth isnt high,minimum is 1.5 time pipe diameter. May improve soil body and keep control surface steady and land subsidence by means of reasonable grouting mode. Transforms is minimum ,the transportation and treatment for spoil are convenient and easy, good operation environment ,safe operation and fit for large calibre pushing pipe.

Production main characteristic
