Formwork system for inverted arch trestle trolley

Abstract

The invention provides a formwork system for an inverted arch trestle trolley. According to the formwork system for the inverted arch trestle trolley, the inverted arch formwork is formed by hinging afixed inverted arch formwork body and a movable inverted arch formwork body, when movable inverted arch faces located on the two sides of an inverted arch layer need to be demolded, demolding can beachieved by controlling the movable inverted arch formwork body to be turned over, and the demolding speed can be increased; meanwhile, when an inverted arch formwork system does not need to be used,the movable inverted arch formwork can be overturned and contracted, so that pouring construction of filling layer concrete is facilitated, and operation is quite convenient; moreover, the formwork system composed of the inverted arch formwork system and a central ditch formwork can be driven by other traction mechanisms to achieve inverted arch operation construction of the whole tunnel with thesame section after one-time installation is completed, assembly and disassembly of the formworks are omitted, the labor intensity of workers is greatly relieved, the labor cost is saved, and the construction efficiency and the construction quality are improved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a template system for an inverted trestle trolley. Background technique [0002] At present, the tunnel inverted arch construction in my country cannot be fully mechanically operated. In each construction cycle, there are handling, assembly, and dismantling work, and there are a lot of manual repetitive operations. On the one hand, the labor intensity of the workers is high, on the other hand, the construction is interrupted, and continuous operations cannot be formed, resulting in low construction efficiency and affecting the construction progress. Especially the formwork system composed of the inverted arch formwork system and the central ditch formwork, because of its complex structure, large volume and high requirements for the positioning of the formwork, if it is frequently disassembled and assembled during the construction process, it will not only cause manpow...

Problems solved by technology

[0002] At present, the tunnel inverted arch construction in my country cannot realize all-mechanical operations. In each construction cycle, there are handling, assembly, and dismantling tasks, and there are a lot of manual repetitive operations.

On the one hand, the labor intensity of the workers is high, on the other hand, the construction is interrupted, and continuous operations cannot be formed, resulting in low construction efficiency and affecting the construction progress

Especially the formwork system composed of the inverted arch formwork system and the central ditch formwork, because of its complex structure, large volume and high requirements for the positioning of the formwork, if it is frequently disassembled and assembled during the construction process, it will not only cause manpower Waste of resources, and it is easy to reduce the positioning accuracy of the formwork system and reduce the construction quality of the inverted arch
