Temporary support device special for tunnels and bridges

Abstract

The invention relates to a temporary support device special for tunnels and bridges The temporary support device special for the tunnel and the bridge comprises a baseboard, the front end and the back end of the baseboard is symmetrically provided with two limit fixed devices, a rise and fall hydraulic cylinder is symmetrically arranged on the upper end of the baseboard, the top of the rise and fall hydraulic cylinder is fixed on a batter board through flange, two control apparatus are arranged on the upper end of the batter board, a regulation column is arranged between the two control apparatus. A support device is arranged on the upper end of the regulation column, the fixed devices, the control apparatus, and the regulation column are used cooperatively to be finished the tunnel and bridge temporary support technology. The temporary support device special for tunnels and bridges solves the difficult problems that the existing tunnels and bridges construction during the temporary support constructing, the material like concrete and steel frame are processed into the temporary support by workers, the cost time is long, the progress of works is influenced, the road works are constructed correspondingly aim at different structures, the labour intensity is high, the operation is complex, the resource is wasted, and the work efficiency is low. The temporary support automation adjusting function is realized.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment for tunnels and bridges, in particular to special temporary support equipment for tunnels and bridges. Background technique [0002] During the excavation process of tunnel and bridge construction, due to the influence of factors such as soil quality, bearing capacity and drainage, it is necessary to provide temporary support for the designated construction location to prevent collapse and rock slippage during the construction of tunnel bridges from affecting the progress and life of the project. Safety issues. At present, most of the support methods in the construction process of tunnel bridges are to choose artificial methods to process materials such as concrete and steel frames into temporary supports. This temporary support has high strength and rigidity, which can fully meet the safety requirements. However, it takes a long time to build this kind of temporary support, and the i...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a special temporary support equipment for tunnel bridges, which can solve the problem of manual processing of concrete and steel frames into temporary supports in the construction process of existing tunnel bridges, which takes a long time. , Large investment, affecting the progress of the project, need to build corresponding temporary support for different structures of the construction surface, labor intensity of workers, complex operation, can not be reused, waste of resources and low work efficiency and other problems, can realize the automatic adjustment of temporary support The structure is simple and light, does not require manual operation, will not affect the construction progress of tunnel bridges, and has the advantages of repeated use, resource saving, low consumption, support stability, simple operation and high work efficiency.
