Function: While carrying out construction under the bridge body, it can allow vehicles to pass through the filling layer through the trestle to reach the lower steps, perfectly matching the inverted arch (bottom plate) concrete construction under various excavation methods of the step method, achieving the construction requirements of early closure and early formation of the ring. Product advantages:
1. The span of the trestle bridge is large, which can meet the requirements of pouring inverted arch concrete in three working conditions: 12 meters, 24 meters, and 36 meters at once, greatly improving the speed of inverted arch construction.
2. The strength of the trestle is high, and it can safely pass through various construction vehicles weighing no more than 60 tons.
3. The space above the trestle is spacious, making it convenient for various construction vehicles to pass. Concrete tankers can easily pour concrete on both sides of the trestle, and excavators can also rotate on the trestle without obstacles, making it easy to clean up residual slag from the inverted arch.
4. All components of the trestle adopt hydraulic transmission, ensuring smooth operation and high reliability.       Luoyang Gaofei Bridges and Tunnel Machinery Co., Ltd was established in , located in Luoyang,Henan province. Our main products are intelligent automatic pouring lining trolley, lining trolley without gantry frame, automatic waterproof boardtrolley, self-propelled inverted arch trestle, ditch cable trough trolley,constant temperature and humidity spray maintenance trolley,multi-function arch mounting trolley, single-line steering platforms, various shaped templates and shield machine accessories are necessary for tunnelconstruction, a strong guarantee for the tunnel construction process, and anecessary part of the industrial chain to strengthen the chain.

Problems solved by technology

[] 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 progressEspecially 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.

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 [] 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 [] 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...
