Earth pressure balance pipe jacking machine
| Technical performance and characteristics | |
| ● TP type earth pressure balance pipe jacking machine is a patented product developed by GuangXin heavy duty. Its patent number is ZL200920067574.5. | |
| ● TP type earth pressure balance pipe machine is a kind of medium and large caliber pipe jacking machine which is suitable for wide soil range. It has the function of improving soil: by adding mud, the original plastic, fluidity and pervious soil can be changed into better plasticity, fluidity and impermeable soil. | |
| ● It can be applied to silt with N value of 0 and gravel and cobble layer with N value of 50. | |
| ● After the construction, the ground settlement is small, the disposal of the waste soil is simple, and the construction can be done in the shallow overburden soil with more than 0.8 times the outer diameter of the pipe. Since the opening of the machine rate reached 100%, so the soil pressure in soil showed more appropriate. | |
