Tunnel supporting arch frame manufacturing system and manufacturing method

Abstract

The invention discloses a tunnel supporting arch frame manufacturing system. The tunnel supporting arch frame manufacturing system comprises a main reinforcement conveying and bending mechanism, a middleware conveying mechanism, a fixed connecting mechanism, a rotary guiding mechanism and a control mechanism. Firstly, the main reinforcement conveying and bending mechanism is controlled to convey and bend a main reinforcement, and the main reinforcement is bent in the circumferential direction of a tunnel; the middleware conveying mechanism is controlled to convey a formed middle connecting piece to a preset position of the bent main reinforcement; then, the fixed connecting mechanism is controlled to fix the middle connecting piece located at the preset position to the bent main reinforcement, the main reinforcement and the middle connecting piece are fixedly connected into a whole, and the main reinforcement and the middle connecting piece are assembled in stages; and finally, the rotary guide mechanism is controlled to guide the main reinforcement fixedly connected with the middle connecting piece to be tightly attached to the inner wall of the tunnel, so that the main reinforcement and the middle connecting piece are spliced to form an arch frame main body. The tunnel supporting arch frame can be automatically spliced through the control mechanism, the automation degree is high, the splicing efficiency is high, and therefore efficient and continuous splicing can be achieved. The invention further discloses a tunnel supporting arch frame manufacturing method.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a manufacturing system for tunnel support arches. The invention also relates to a manufacturing method of the tunnel support arch. Background technique [0002] In recent years, with the development of tunnel engineering in the direction of long, large and deep, more and more tunnels have been constructed through soft rock and high rockburst strata in high ground stress areas, especially in soft rock and broken surrounding rock strata. Soft rock itself has strength and The elastic modulus and other mechanical parameters are low, and the water softening effect is obvious. After excavation, the surrounding rock self-stabilization time of this type of tunnel is relatively short. In order to ensure the smooth construction and operation safety of the tunnel, the tunnel is usually inseparable Therefore, it is particularly necessary to improve the production process of the tunnel sup...

Problems solved by technology

[0003] However, most of the existing tunnel support arches are assembled manually, which is difficult to achieve efficient and continuous assembly, so that the assembly speed and quality of tunnel support arches are largely restricted by human factors, especially in In the stratum operation environment with high ground stress and large deformation, the safety of construction personnel is greatly threatened
