Equipment and method for assembling arched steel structure in tunnel

Abstract

The invention discloses equipment and a method for assembling an arched steel structure in a tunnel. The equipment for assembling the arched steel structure in the tunnel comprises the arched steel structure and an assembling machine, the erector comprises a vehicle frame, a moving mechanism fixedly arranged on the lower side of the vehicle frame and an arm frame rotationally arranged at the front end of the vehicle frame, the arm frame is provided with a grabbing and lifting mechanism used for grabbing and lifting the arched steel structure, and the front end of the vehicle frame is further provided with a driving mechanism for driving the arm frame to turn over around the vehicle frame. According to the assembling equipment for the arched steel structure in the tunnel, grabbing and lifting of the arm frame are flexible, the whole-ring arched steel structure can be grabbed and lifted at a time from the ground, high-altitude operation is avoided, multiple times of assembling and follow-up operation amount are reduced, and the assembling equipment has the remarkable advantages that assembling is rapid and efficient, the assembling quality is easy to control and guarantee, and the assembling risk is reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an assembly device for an arched steel structure in a tunnel. The invention also relates to a method for assembling an arched steel structure in a tunnel. Background technique [0002] Traditional tunnel construction mainly adopts manual arrangement of steel mesh, artificial formwork, artificial reinforcement, and then concrete pouring. After the concrete solidifies, manual formwork removal is carried out. There are many problems such as high manual labor intensity, high construction risk factor, long construction period, The disadvantage of a low level of mechanization. [0003] Compared with traditional concrete structures or prefabricated concrete structures, prefabricated steel structures are more in line with current buildings due to their advantages such as fast installation speed, easy quality control and assurance, lighter structure weight, good seismic perfo...

AI Technical Summary

Problems solved by technology

[0004] In the actual construction process of the arched steel structure in the tunnel, due to the complex and harsh road conditions, the heavy steel structure is prone to safety hazards such as slipping and rollover during transportation by wheeled forklifts; The assembly of steel structures is difficult; at the same time, the existing assembly equipment generally has a low degree of mechanical automation and inflexible operation. The steel structures need to be docked and closed at high altitudes. The assembly efficiency is low and the quality is difficult to guarantee
