Tunnel excavation equipment for excavating any section by using high-speed projectiles

Abstract

The invention relates to the technical field of tunnel excavation equipment, in particular to tunnel excavation equipment for excavating any section through high-speed projectiles, which comprises a machine body and a projectile launching system, the projectile launching system comprises a projectile launcher and a high-pressure pump connected with the projectile launcher through a high-pressure pipeline, and the projectile launcher is used for launching the projectiles; the projectile launcher is assembled on the machine body through a mounting structure capable of at least changing the up-and-down position and the left-and-right position, so that the section with the needed shape is directly excavated by adjusting the launching angle of the projectile launcher. The projectile launcher is directly used for excavation, the milling and excavation head is matched to trim the profile of the section, the section with the needed shape is directly excavated by changing the launching angle of the projectile launcher and adjusting the coverage range, the excavation size can be adjusted at will, the equipment universality and flexibility are high, a traditional shield body and a traditional cutter head do not need to be arranged, and the construction cost is reduced. A large amount of tool loss caused by high rock hardness is avoided, the manufacturing cost is reduced, and the tunneling efficiency is higher than that of a traditional drilling and blasting method.

Description

technical field [0001] The invention relates to the technical field of tunnel excavation equipment, in particular to a tunnel excavation equipment that utilizes high-speed projectiles to excavate any section. Background technique [0002] The rock tunnel boring machine (TBM) currently used in tunnel excavation has the most suitable surrounding rock strength range of 30 to 150MPa. Under the geological conditions where the surrounding rock is too hard and wear-resistant, the tunneling efficiency of the TBM is limited. It is also very unfavorable in itself, and in this environment, the equipment is often at full load or even overloaded, and key components often have accidents, and the technical level of operators is relatively high. The progress of the project increases the project cost. Although some scholars at home and abroad have proposed some new auxiliary rock-breaking technologies, such as high-pressure water jet, particle impact, laser rock-breaking, plasma rock-breaki...
