pipe jacking machine vs tunnel boring machine
The pipe jacking machine and tunnel boring machine are both innovative solutions for underground construction, each boasting distinct functions, technological features, and applications. The pipe jacking machine is designed to install pipes underground without the need for surface excavation. It operates by thrusting precast pipes through the ground, guided by a jacking frame. On the other hand, the tunnel boring machine (TBM) is a large, complex machine used to excavate tunnels with a circular cross-section. TBMs feature rotating cutting heads equipped with disc cutters or toothed cutters, depending on the ground conditions. Both machines offer versatile solutions for civil engineering projects, with pipe jacking being ideal for shorter, straighter installations like utility lines, and TBMs excelling in creating long, large-diameter tunnels for subways, water tunnels, and more.
