Dry goods sharing, take you to understand the mud-water balance pipe jacking machine in one minute
The mud-water balance pipe jacking machine is an underground tunnel excavation machine that uses mud balance pressure to push the machine head forward. Compared with the traditional shield machine, the mud-water balance pipe jacking machine performs better in the case of harsh
Introduction to the precautions of the rock pipe jacking machine, come and collect it!
The rock pipe jacking machine plays an important role in tunnel excavation, and its correct use is the premise to ensure the smooth progress of tunnel construction. Before use, read the instruction manual carefully to understand its use method and safe operation procedures. During use, the following points should be noted:

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.
More than ten years of experience in the design and manufacturing of pipe jacking machines
