Tunnel construction shock absorption type water-rich sand layer detection perforating device

Abstract

The invention discloses a tunnel construction shock absorption type water-rich sand layer detection perforating device, and relates to the technical field of tunnel perforation. The tunnel construction shock absorption type water-rich sand layer detection perforating device particularly comprises a fixing support, an upper bottom plate and gas pressure rods. The fixing support is welded and connected with the upper bottom plate, the upper bottom plate is mounted at the bottom of the fixing support, a housing is mounted on the upper surface of the upper bottom plate, an air blower is arranged inside the housing, and support blocks are mounted on the surface of the bottom of the upper bottom plate. The tunnel construction shock absorption type water-rich sand layer detection perforating device has the advantages that the tunnel construction shock absorption type water-rich sand layer detection perforating device is provided with rubber blocks, accordingly, abrasion of the surfaces of drilling tools due to direct contact between drilling bits and the drilling tools can be prevented, shock absorption effects can be realized for the drilling tools by the aid of the elasticity of the rubber blocks, shock generated by the drilling tools in work procedures can be reduced, and perforation work can be advantageously carried out by the tunnel construction shock absorption type water-richsand layer detection perforating device; the drilling tools are distributed, accordingly, the perforation work can be facilitated, and the perforation work efficiency of the tunnel construction shockabsorption type water-rich sand layer detection perforating device can be improved.

Description

technical field [0001] The invention relates to the technical field of tunnel drilling, in particular to a shock-absorbing drilling device for detecting water-rich sand layers used in tunnel construction. Background technique [0002] Drilling refers to drilling or drilling holes in solid or solid materials with a tool with a drill bit. The installation hole position of the tunnel contact wire mounting frame and the top of the tunnel are as high as about 5M. The tunnel drilling machine has not been developed and used. Previously, the drilling work of these holes had workers on the scaffold manually holding the percussion drill for drilling, which was labor-intensive, low work efficiency, and difficult in quality control. [0003] A road drilling construction equipment disclosed in the Chinese invention patent application publication specification CN108422181U, although the road drilling construction equipment solves the problem of high labor intensity and danger of manual op...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a shock-absorbing drilling device for detecting water-rich sand layers for tunnel construction, which solves the problem that the vibration amplitude of the device during the drilling process proposed in the above-mentioned background technology is too large, which affects the drilling performance. The accuracy of the hole, and the friction generated inside it during the drilling process, affects the service life of the part
