Problems solved by technology
[0005] 1. In the process of hoisting and docking, there will inevitably be some shaking. Therefore, collisions are easy to occur during the docking. If the impact is strong, it will not only affect the change of the angle or position of the installed arc parts, but also very likely cause Collision damage, while installation efficiency is very low;
[0006] 2. Since the adjustment of the angle and position formed by the crane can only be that the arc is in a suspended state, once the arc is erected on the arc wall at the bottom of the tunnel, it is very difficult to fine-tune it. Therefore, it is difficult to achieve the alignment and installation required precision

The invention relates to a mounting process for an internally-supported tunnel arc-shaped piece with multi-degree-of-freedom fine adjustment. The mounting process comprises the following steps: S1, hoisting and moving the arc-shaped piece; s2, fine adjustment of the arc-shaped piece; and S3, the arc-shaped piece is assembled. On one hand, under the cooperation of the crane, the internal support and the multi-degree-of-freedom adjustment and support adjustment alignment machine, position adjustment and displacement of the to-be-installed arc-shaped piece relative to the installed arc-shaped piece are stably implemented; on the other hand, on the basis of the installed arc-shaped pieces, safe, efficient and high-precision assembly of the to-be-installed arc-shaped pieces can be implemented one by one in the length direction of the tunnel.
Description
technical field [0001] The invention belongs to the technical field of tunnel engineering, and in particular relates to an installation process for tunnel arc parts with internal support and multi-degree-of-freedom fine-tuning. Background technique [0002] As everyone knows, a tunnel is a building built underground, underwater or in a mountain, and laying a railway or building a road for the passage of motor vehicles. The construction process of the tunnel mainly includes tunnel planning, survey, design, penetration control measurement and construction, etc. Therefore, whether it is construction or use, the tunnel process is cumbersome and complicated. [0003] However, in a shield tunnel designed with a partition wall, it is necessary to install the arc-shaped parts at the bottom of the tunnel first. At present, the method used for the arc-shaped parts is basically a crane. Under the adjustment and alignment of the crane, the arc-shaped The parts are moved to the area to ...
