Abstract

The invention relates to a subway crossing overpass bridge construction protection device, which relates to an overpass bridge construction technology, and comprises protection cloth and two groups of connecting mechanisms, the protective cloth comprises two pieces of splicing cloth which are arranged in an inclined mode, and the bottoms of the two pieces of splicing cloth are connected together to form the protective cloth of a V-shaped structure. The two groups of connecting mechanisms are in one-to-one correspondence with the two pieces of splicing cloth respectively, and the connecting mechanisms are used for fixing the two pieces of splicing cloth to the two sides of the bridge respectively. In the splicing construction process of the two bridge modules, the protection device can shield and collect residual materials in the construction process so as to reduce the influence on the environment below the bridge.

Description

technical field [0001] The present application relates to the construction technology of a flyover bridge, in particular to a construction protection device and a construction method for a crossing subway flyover bridge. Background technique [0002] During the construction of the cross-line bridge across the subway, when the two adjacent bridge modules are spliced ​​with concrete, there will often be concrete residues falling down. In order to avoid causing damage to pedestrians and vehicles under the residue In order to avoid damage, the area under the bridge is generally closed temporarily, and the traffic will be resumed after the construction is completed. In many cases, the construction period of the bridge is generally long, which leads to a long time of traffic closure under the bridge, which brings a lot of inconvenience to people's normal travel. Contents of the invention [0003] In order to improve the problem in the related art that traffic under the bridge ne...
