Tunnel bridge construction temporary support equipment

Abstract

The invention relates to tunnel bridge construction temporary support equipment comprising a bottom plate. Two fixing devices capable of realizing limiting are symmetrically mounted at the front end and the rear end of the bottom plate, lifting hydraulic cylinders are symmetrically mounted at the upper end of the bottom plate, and the top ends of the lifting hydraulic cylinders are mounted on a positioning plate through flanges; two adjusting devices are symmetrically mounted at the upper end of the positioning plate, an adjusting column is mounted between the two adjusting devices, and a supporting device is mounted at the upper end of the adjusting column; and a technology for tunnel bridge temporary support is completed through mutual cooperation of the fixing devices, the adjusting devices, the adjusting column and the supporting device. According to the tunnel bridge construction temporary support equipment, the difficult problems that in the existing tunnel bridge construction temporary support building process, materials such as concrete and steel frames need to be manually processed into temporary supports, the consumed time is long, the project progress is affected, the corresponding temporary supports need to be constructed according to construction faces of different structures, the labor intensity is high, operation is complex, sources are wasted, and the working efficiency is low can be solved, and the function of automatically adjusting the temporary supports can be achieved.

Description

[0001] The present invention is a divisional application of a Chinese patent application filed on April 26, 2017 with the application number 2017102803588 and the title of the invention is a temporary support equipment for tunnels and bridges. technical field [0002] The invention relates to the technical field of mechanical equipment for tunnels and bridges, in particular to temporary support equipment for tunnel and bridge construction. Background technique [0003] 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 ma...
