Problems solved by technology

[0004] Existing non-excavation tunneling equipment usually uses large cutters with a diameter slightly larger than the cross-section for excavation, and most of them have soil bins. When the entire cutterhead is twisted, a huge driving torque and a huge driving thrust are required, so that the entire rotary D

Abstract

The invention discloses a tunnel boring machine hammer type tunneling method and a trenchless tunnel boring machine applying the same. The method mainly comprises: a step 1, an impact hammer carries out tunneling for one propelling stroke to form a point tunneling region; a step 2, the impact hammer returns and changes tracks, and keeps on carrying out tunneling for one propelling stroke according to the step 1 to form a next point tunneling region which is overlapped with and connected to the point tunneling region in the previous step; a step 3, the step 2 is repeatedly completed for many times to form a plurality of point tunneling regions, the plurality of point tunneling regions are connected to form a first middle tunneling region; a step 4, the impact hammer changes tracks, and completes the steps 1, 2 and 3 in sequence to form a next middle tunneling region; and a step 5, the step 4 is repeatedly completed for many times to form a plurality of middle tunneling regions, and the plurality of middle tunneling regions are connected to complete surface tunneling work of a whole tunneling region. According to the method, frontal resistance can be reduced, and the structure of the whole tunneling system can be simplified.

Description

technical field [0001] The invention specifically relates to a hammer type excavation method of a tunnel boring machine and a non-excavation tunnel boring machine applying the method. Background technique [0002] Tunnel boring machine is an advanced technical equipment with high speed, good quality and high safety performance in urban subway construction and pipe gallery construction. The interval tunnel constructed by tunnel boring machine can achieve weak disturbance to the soil, does not affect the ground buildings and traffic, and reduces a large number of above-ground and underground demolition. The technical development and application of this equipment has very broad prospects in the field of underground engineering in various countries. [0003] Tunnel boring machine is the main equipment for trenchless tunnel construction. Its excavation method is: use a large cutter head with a diameter slightly larger than the outer diameter of the machine to rotate and excavate...
