Embodiment Construction

[0019] The present invention will be further described below in conjunction with drawings and embodiments.

[0020] Such as figure 1 According to the principle of pipe jacking construction, the work of the pipe jacking machine starts from the working well, and the main jacking system pushes the pipe jacking machine forward. The earth machine will output the spoil.

[0021] Such as figure 2 , the overall structure design of the earth pressure balance pipe jacking machine includes mechanical structure design, hydraulic system design and electrical control system design.

[0022] Such as image 3 , the hardware of this system adopts PLC as the controller, realizes the master-slave station communication through the CC-Link module, and realizes the control of the main top and the cutter head and other systems, and adopts the way of double pump oil supply to control the top of the main top control system. Improve the design of the advance speed and improve the construction effi...
