Internationally, generalized shield machines can also be used in rock formations, differing only from open tunnel boring machines. In China, a tunnel boring machine used for a soft soil stratum is customarily called a shield tunneling machine, a tunnel boring machine used for a rock stratum is called TBM, tunnel construction by a shield tunneling machine has the characteristics of high automation degree, labor saving, high construction speed, one-step tunneling, no influence of weather, controllable ground settlement during excavation, reduction of influence on ground buildings, no influence on ground traffic during underwater excavation and the like, under the conditions of long tunnel line and large buried depth, construction by the shield tunneling machine is more economical and reasonable, and the basic working principle of the shield tunneling machine is that a cylindrical steel component is pushed forwards along the tunnel axis while excavating soil. The casing of the cylinder assembly, the shield, acts as a temporary support for the excavated, not yet lined tunnel section, bearing the pressure of the surrounding soil layers and sometimes also the groundwater pressure and the water that is trapped outside. Excavation, dumping, operation such as lining cutting go on under the shield of shield, and the excavation of shield structure machine mainly relies on the blade disc rotation to tunnel, and the blade disc directly influences the work efficiency of shield structure machine, but current blade disc is mostly monolithic, can only the single direction rotate during the rotation, and work efficiency is lower, and the difficult broken excavation of topography such as some harder rocks.
