Self-propelled trestle trolley for inverted arch trestle trolley

Abstract

The invention provides a self-propelled trestle trolley for an inverted arch trestle trolley. After an inverted arch formwork system is installed at a time, the inverted arch formwork system can be dragged by a trestle trolley to achieve inverted arch operation construction of a whole tunnel with the same section, formwork assembling and disassembling are omitted, full-automatic mechanical controlmoving and positioning are adopted, labor intensity of workers is greatly reduced, labor cost is saved, and construction efficiency and construction quality are improved; and meanwhile, the invertedarch formwork system is detachably connected with the trestle trolley, a separation mode is simple, the inverted arch formwork can be ensured not to interfere with construction of other procedures inthe procedures of inverted arch excavation, wire-tie and the like, and control is flexible and convenient.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a self-propelled trestle trolley for an inverted arch 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 inverted arch formwork system, because of its complex structure 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 a waste of human resources, but also easily lead to the positio...

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 inverted arch formwork system, because of its complex structure 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 a waste of human resources, but also easily lead to the positioning accuracy of the inverted arch construction formwork. Reduce the construction quality of the inverted arch. Moreover, because the inverted arch formwork system is relatively large, it is extremely inconvenient to move in the tunnel by manpower alone and the positioning accuracy is difficult to guarantee.
