Description

Technical Field

[0001] The utility model relates to the technical field of highway bridge construction, in particular to a rotary temporary support for a highway bridge. Background Art

[0002] As the name suggests, a temporary support is a simple support used temporarily. It is a construction process method for the erection of prefabricated box beams and T-beams during the construction of highway bridges. The temporary support can adjust the height and levelness to keep the bridge stable during installation, so as to facilitate subsequent construction work. Existing temporary supports for highway bridges have certain disadvantages when used. Sand is poured into the interior of the temporary support. After it is placed at the bottom of the bridge, it does not fit completely with the bridge, and its upper and lower heights are inconvenient to adjust. In order to improve the stability of the support, the sand needs to be soaked in water to improve the performance of the support. When the support is removed, the sand inside the support is wet and difficult to discharge, which consumes time and manpower, and the installation operation of the sand discharge pipe is cumbersome. For this reason, we propose a rotating temporary support for highway bridges. Utility Model Content
