Embodiment 1

[0016] The excavator auxiliary steel arch installation process is characterized in that it includes the following steps:

[0017] (1) Weld a section of channel steel with a steel plate with a thickness of 16mm to form a slot. The size of the slot is: 1.1m in length, 0.2m in width, and 0.25m in height;

[0018] (2) After the processing of the card slot is completed, drill three holes on the web of the card slot, and also drill three holes on the bucket of the excavator at the same time, the holes on the web of the slot and the holes on the back bucket of the excavator Correspond to the holes, and then use three sets of bolts to bolt and fix the card slot and the back bucket of the excavator together;

[0019] (3) On the ground in the tunnel, manually assemble the steel arches of each section into a whole;

[0020] (4) Put the arch of the assembled steel arch into the slot of the back bucket of the excavator, then start the bucket of the excavator to lift slowly, and erect the ...

Abstract

The invention discloses an installing process of auxiliary excavator steel arches. The installing process includes the operation steps that a steel plate is welded into a steel channel to form a clamping groove, the clamping groove and an excavator back bucket are fixedly bolted through bolts, then all the steel arches are spliced into a whole on a ground in a tunnel, the arch parts of the spliced steel arches are put into the clamping groove of the back bucket, the steel arches are wholly erected, by means of the arrangement of an excavator, the steel arches are put into the corresponding position determined in advance, the steel arches are fixed through feet-lock bolts, and meanwhile the adjacent steel arches are connected through longitudinal connecting ribs. The excavator is modified, the clamping groove is fixed to the back bucket, the spliced steel arches are wholly hoisted, resources of a construction site are reasonably used, the production efficiency is greatly improved, construction quality is ensured, workers are liberated from heavy manual labor, and safety is ensured.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an excavator auxiliary steel arch installation process. Background technique [0002] At present, in the design of compound-lined tunnels in China, steel arch frames are often used, which are suitable for strong support of weak surrounding rock. In normal construction, the steel arch is generally divided into several units according to the outline of the tunnel, and transported to the site for manual assembly in sections to form a whole arch. Because the steel arch is heavy, it is labor-intensive, time-consuming and labor-intensive to construct entirely by manpower, and it is relatively dangerous. If professional arch installation equipment is used, the cost is relatively expensive, which will increase the cost of the project. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides an excavator-assisted steel a...
