Abstract

The invention relates to the technical field of full-face tunnel boring machines, in particular to a method for increasing the rigidity of a continuous cutter head of a full-face tunnel boring machine and the hook face cutter head. The method includes the steps that the deflection of a circle where center points of all disc cutters of the continuous cutter head are located in the tunneling process; and the continuous cutter head is prefabricated, the circle where the center points of the disc cutters are located protrudes in the tunneling direction of the full-face tunnel boring machine, and the protruding displacement of the circle where the center points of the disc cutters are located is equal to the deflection of the circle where the center points of the disc cutters are located. The hook face cutter head is prefabricated according to the method. By means of the method and the hook face cutter head, the rigidity of the cutter head of the full-face tunnel boring machine can be effectively increased, the rock breaking efficiency of the disc cutters on the cutter head is guaranteed, the service life of the cutter head and the cutters of the full-face tunnel boring machine is accordingly prolonged, and the operation efficiency of the cutter head and the cutters is improved.

Description

technical field [0001] The invention relates to the technical field of full-section tunnel boring machines, in particular to a method for increasing the rigidity of a continuous cutterhead of a full-section tunnel boring machine and a curved cutterhead. Background technique [0002] Full-face tunnel boring machine is the general name of Full Face Rock Tunnel Boring Machine (TBM) and Shield (Shield). The factory-like assembly line construction tunnel equipment integrated with electricity, liquid, light, gas and other systems has the advantages of fast excavation speed, environmental protection, and high comprehensive benefits. It can realize the construction of long and deep tunnels in complex geological formations that are difficult to achieve by traditional drilling and blasting methods. The application in China's railway, hydropower, transportation, mining, municipal and other tunnel (road) projects is growing rapidly. [0003] At present, the cutter head of the full-face...
