NPD slurry balance tunnel pipe jacking machine_Yangzhou Dilong Machinery Co., Ltd.

NPT3700 mud-water balance shield machine 1) The shield machine can carry out long-distance propulsion, and can make small-radius turns and three-dimensional turns; 2) The tunneling speed is faster. Because the pipe jacking can be carried out, compared with the shield machine, the Hume pipe is transported in the pit during the construction, and there is no need to use a segment assembly machine for assembly, and the tunneling speed is significantly accelerated. Half of the pipe jacking and half of the shield can save at least a quarter of the construction period than a simple shield. 3) The launching well and the receiving well are relatively small, so segmented launching can be performed. 4) Low construction cost. Compared with shield construction, pipe jacking construction significantly reduces costs and has better economic applicability.
