[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 investment in material and manpower is relatively large, which affects the progress of tunnel and bridge construction. During the construction of tunnel and bridge, it is necessary to build corresponding temporary supports for the construction surfaces of different structures. The labor intensity of personnel is high, the operation is complicated, and the work efficiency is low. There are working errors in the manual construction of temporary supports, and the stability of the temporary supports cannot be guaranteed. After the construction is completed, the built temporary supports need to be dismantled and cannot be reused. , resulting in a waste of resources

[0003] There are also some technical solutions in the prior art, such as the Chinese patent application number CN201710280358.8, which includes a base plate, two fixed devices that can be limited are symmetrically installed at the front and rear ends of the base plate, and lifting hydraulic pressure is installed symmetrically on the upper end of the base plate. The top of the lifting hydraulic cylinder is installed on the positioning plate through the flange. Two adjustment devices are symmetrically installed on the upper end of the positioning plate. An adjustment column is installed between the two adjustment devices. A support device is installed on the upper end of the adjustment column. Adjusting device, adjusting column and supporting device cooperate with each other to complete the process of temporary support of tunnel bridge, which solves the problem of manual processing of concrete and steel frame and other materials into temporary support in the construction process of existing tunnel bridge construction, which is time-consuming long, affect the progress of the project, need to build corresponding temporary supports for different structures of the construction surface, labor-intensive, complex operation, waste of resources and low work efficiency, etc., but the equipment structure realized by this scheme is relatively complex and takes up a large space , at the same time, there are no measures to ensure the stability of the equipment itself during use, and the stability during the support process of the equipment cannot be guaranteed. At the same time, the universal wheels on the equipment are easy to sink into the ground during use, which affects the movement of subsequent equipment
