Embodiment Construction
[0022] The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.
[0023] A multi-hole punching and bolting precision control device for tunnels, which is used for the precision control of the drilling and bolting process before installing the porous flange base. The bottom of the porous flange to be installed is an isosceles trapezoid with three holes , the precision control device is composed of device I1 and device II2, and the shape and size of the orthographic projection of device I1 and device II2 are the same as the shape and size of the porous flange base to be installed, and they are all equal-sized isosceles trapezoids, Wherein, the device I1 is a flat plate 101 made of a steel plate. A triangular opening I104 is opened in the center of the flat plate 101. In the opening I104, a plurality of auxiliary rods I105 intersecting at the same point are welded. The point is the auxiliary center, ...

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...
