Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] Such as Figure 1 ~ Figure 4 As shown, a new type of laser rock-breaking mode TBM of the present invention includes a cutter head device and a laser system. A certain number of laser heads 1 are evenly mounted on the cutter head according to certain rules, and corresponding laser holes 2 are arranged correspondingly. 1 emits laser light to the rock through the laser hole 2; the laser system includes a laser generator 5, an optical fiber cable 3, a beam ...

Abstract

The invention discloses a novel laser rock breaking mode TBM. The TBM comprises a cutter head device and a laser system. The laser system comprises a laser generator, optical fibers and cables, lightsplitters and laser heads, the laser heads are uniformly carried on the cutter head of the TBM according to a certain rule, and the cutter head is provided with corresponding laser holes. In the working process of the TBM, the laser heads emit laser beams to irradiate rock through the corresponding laser holes to generate light spots, the rock absorbs laser heat, is thermally crushed and falls offautomatically, and then the crushed rock is collected by a scraper on the cutter head to enter a slag chute. The TMB can reduce the construction difficulty of a tunnel and reduce the construction cost. Meanwhile, the disturbance of mechanical excavation to a stratum can be reduced by adopting laser irradiation rock breaking, and the construction safety is improved.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment and relates to a novel laser rock breaking mode TBM. Background technique [0002] Due to the high excavation efficiency of TBM (tunnel boring machine, tunnel boring machine), and the safety is much higher than that of drilling and blasting excavation, so more and more mountain tunnels are constructed by TBM. When encountering high-strength rocks, such as granite, marble, etc., the TBM excavation efficiency will drop significantly, the tool will be consumed quickly, and the construction cost will increase. How to effectively improve the rock-breaking efficiency of TBM is one of the key technologies in TBM research. [0003] In the next 10 years, the excavation mileage of various types of tunnels will be about 20,000 kilometers, and the demand for hard rock TBM equipment will be about 600. The excavation efficiency of these TBM equipment can be effectively improved, and the e...
