A kind of excavation depth adjustable tunnel drilling equipment and its construction method

Abstract

The invention discloses tunnel drilling equipment with adjustable excavation depth and a construction method thereof and relates to the technical field of tunnel drilling. The tunnel drilling equipment comprises a base body, the right side of the upper surface of the base body is fixedly connected with a fixing column, the left side surface of the fixing column is fixedly connected with a hydraulic cylinder, a moving mechanism is arranged on the lower part of the base body, a first sliding groove is formed in the left side of the upper surface of the base body, a fixing rod is placed on the upper part of the base body, the right side surface of the fixing rod is fixedly connected with the output end of the hydraulic cylinder, and the bottom surface of the fixing rod is fixedly connected with a first sliding block matched with the first sliding groove. The tunnel drilling equipment with adjustable excavation depth and the construction method thereof have the function of adjustable excavation depth and have the advantage that the excavation depth can be conveniently adjusted, the occurrence of unfulfillment of the excavation depth caused by the influence of geographical environment is prevented, the stability of the equipment in an excavating process is ensured, and the occurrence of the shaking of the equipment caused by the collision in the excavating process is prevented.

Description

technical field [0001] The invention relates to the technical field of tunnel drilling, in particular to a tunnel drilling device with adjustable excavation depth. Background technique [0002] Tunnels are engineering structures buried in the stratum, and it is a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels. Drilling equipment is required in the process of tunnel excavation. For tunnel excavation, in the process of tunnel excavation, when the moving position of the drilling equipment is restricted and the excavation depth cannot reach the specified depth, a drilling equipment that can adjust the excavation depth is required to realize Drill to the required depth. [0003] The existing tunnel drilling equipment is easily affected by the geographical environment, making it difficult for the excavation depth to reach the specified depth. During the excavation process, the equ...
