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;
[0007] 3. The tunnel does not extend in a straight line, so there will be a certain offset angle (although the angle is relatively small), but if it is not adjusted in time, there will be deviations after the arc-shaped parts are installed, which not only affects the installation accuracy, but also is difficult to implement Correction

The invention relates to a mounting method of an arc-shaped piece capable of deflecting and adjusting along with the center of a tunnel. The mounting method comprises the following steps that S1, the arc-shaped piece is hoisted and moved; s2, deflection adjustment of the alignment adjusting machine; s3, fine adjustment of the arc-shaped piece; and S4, the arc-shaped piece is assembled. On one hand, deflection adjustment is conducted along with deviation of the center of the tunnel, so that the to-be-installed arc-shaped piece moves in the length direction of the to-be-installed section of the tunnel to be attached to the installed arc-shaped piece, and the installation precision is improved; and on the other hand, transverse movement in the length direction of the tunnel in the arc-shaped piece is matched with jacking adjustment in the direction of multiple degrees of freedom, position adjustment and displacement of the to-be-installed arc-shaped piece relative to the installed arc-shaped piece are stably implemented, and therefore safe and efficient assembly of the arc-shaped piece is implemented in cooperation with a crane.
Description
technical field [0001] The invention belongs to the technical field of tunnel engineering, and in particular relates to an installation method of an arc-shaped part that can be adjusted according to the deflection of the center of the tunnel. 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 ...
