Device for controlling multi-hole type punching and bolt implanting accuracy of tunnel

Abstract

A device for controlling multi-hole type punching and bolt implanting accuracy of tunnel consists of a device I and a device II, wherein the device I is a slab of which the center is provided with an opening I, the slab is provided with multiple verifying rods vertical to the surface of the slab and multiple marking holes, the device II is formed by an upper-layer plate and a lower-layer plate, which are parallel to each other, through the combination a guide tube, the outer side of the upper-layer plate is vertically provided with a fixing rod, the centers of the upper-layer plate and lower-layer plate are provided with openings II respectively, the upper-layer plate and the lower-layer plate are respectively provided with multiple verifying holes that matches the verifying rod, the guide tube is vertically fixed between the verifying holes which are oppositely arranged in the upper-layer plate and the lower-layer plate, and forms a punching and verifying channel together with the verifying holes. According to the device for controlling the multi-hole type punching and bolt implanting accuracy of the tunnel, the device I and the device II can complete the accuracy control work of the punching and bolt implanting process before installing a multi-hole flange pedestal within a short time in the manner of alternative verification through 'fixation-verification-correction' operations, the operations are simple, and the effect is remarkable.

Description

technical field [0001] The invention belongs to the field of tunnel engineering construction, and mainly relates to a tunnel multi-hole punching and bolting precision control device, which ensures the accuracy of the tunnel porous flange base punching and anchor bolting process before installation through alternate verification. Background technique [0002] The porous flange base in the tunnel needs to be drilled and implanted with anchor bolts before installation, and the precision of porous drilling and bolting needs to be controlled through corresponding molds. However, in the current construction process, the general molds are mostly It plays the role of marking the hole distance before drilling, and it is difficult to control the accuracy of the direction and spacing of the holes, and it is impossible to verify the effect of the bolt before the bolt is planted. Contents of the invention [0003] The purpose of the present invention is to provide a tunnel multi-ho...
