Fault Diagnosis and Elimination of Pipe Jacking Machine

A Φ1 800 mm muddy water pressurized pipe jacking machine (expandable to 2000mm), the total length of the rotary excavator system is 4705 mm, the cutterhead torque is 354 kN m, the cutterhead speed is 2.3r/min, and the driving power is 30× 3 kW. The stroke of the correcting hydraulic cylinder is 85 mm, and the thrust of the correcting hydraulic cylinder is 980 kN×the total mass of the main engine (t). When the pipe jacking machine jacked 200 m of pipes, the deviation correction system failed, and the deviation correction action could not be produced, so that the construction could not be carried out.

The key of pipe jacking construction depends on the jacking of the main jacking cylinder

Pipe jacking construction refers to the construction process of jacking steel pipes (including multi-section steel pipes) or concrete pipes from point A to point B with hydraulic power without digging trenches on the surface. Technological principle and technological process of pipe jacking construction The open-laid pipeline is changed to use machinery as power to transfer the pipeline from point A to point B under the surface. The main mechanical equipment includes hoisting equipment, high-pressure oil pumps, large tonnage jacks, back piles and back beams, guide rails and unearthed tools, theodolites, and levels.
