Tunneling equipment and control method of tunneling equipment

Abstract

The invention provides tunneling equipment and a control method of the tunneling equipment. The tunneling equipment comprises a walking assembly, a main machine and a controller. The main machine is arranged on the walking assembly, the main machine is provided with a guide rail, a curve-shaped guide part and a drill bit, the curve-shaped guide part is arranged on the guide rail, and the drill bitis connected with the curve-shaped guide part; the controller is connected with the walking assembly and the main machine, wherein the controller controls the drill bit to rotate and controls the curved guide part to move along the guide rail after controlling the walking assembly to move to a preset position. The structure of the tunneling equipment is reasonably arranged, the tunneling equipment tunnels and drills along the curve shape of the surrounding rock, therefore, the drilling depth can be increased in a targeted mode according to the specific actual use condition, so as to meet thehole forming depth requirement, the tunnel arch foot reinforcing requirement can be met, meanwhile, the structure provides a structure foundation for achieving fore-reinforcement and forepoling functions, and then the purposes of preventing arch feet from sinking and improving the surrounding rock stability can be achieved.

Description

technical field [0001] The invention relates to the technical field of excavation equipment, in particular to an excavation equipment and a control method for the excavation equipment. Background technique [0002] In the current excavation of railway tunnels, about 30% to 40% of the geological structure belongs to weak surrounding rocks. Due to the lack of self-bearing capacity and rigidity of the weak surrounding rocks, the arch feet of the support will sink. Once the construction method is improper, it is easy to produce Engineering disasters such as deformation encroachment, support cracking, and partial collapse not only seriously affect construction safety and construction quality, but also adversely affect construction schedule and investment. Many tunnels, including the Taizhongyin Railway Xingwangmao Tunnel, etc., due to the characteristics of poor self-stabilization, large deformation, and water softening of the surrounding rock, led to design changes, extended con...

[0002] In the current excavation of railway tunnels, about 30% to 40% of the geological structure belongs to weak surrounding rocks. Due to the lack of self-bearing capacity and rigidity of the weak surrounding rocks, the arch feet of the support will sink. Once the construction method is improper, it is easy to produce Engineering disasters such as deformation encroachment, support cracking, and partial collapse not only seriously affect construction safety and construction quality, but also adversely affect construction schedule and investment. Many tunnels, including the Xingwangmao Tunnel of the Taizhongyin Railway, etc., due to the poor self-stabilization ability of the surrounding rock, large deformation, and water softening, have led to design changes, extended construction periods, and increased investment

[0003] In related technologies, the use of mechanical equipment for drilling operations has the problems of insufficient rotary drilling force, unable to meet the requirements of tunnel arch foot reinforcement and unable to effectively suppress the deformation of the arch foot
