Construction temporary bridge structure for metro open cut foundation pit expansion end
The invention relates to a construction temporary bridge structure for an expanded end of an open cut foundation pit of a metro, which comprises a temporary steel bridge structure, the temporary steel bridge structure is formed by splicing a plurality of single-truss temporary steel bridges, each single-truss temporary steel bridge comprises I-shaped steel, two steel top plates and a steel web, and the two steel top plates are distributed at two ends of the steel web. The I-shaped steel is arranged between the two steel top plates; the single truss temporary steel bridge splicing piece is used for being spliced with the single truss temporary steel bridge; the pavement layer is paved on the temporary steel bridge structure; the anti-sliding wall is arranged on the periphery of the temporary steel bridge structure in a surrounding mode. By the adoption of the structure, the influence of subway foundation pit construction on the surrounding traffic environment can be reduced, the problem that the width of a construction road at the enlarged end of the subway open-cut foundation pit is insufficient is solved, and compared with a traditional concrete cover plate, the construction method has the advantages that the construction cost is low, materials can be recycled, meanwhile, a steel structure serves as a temporary bridge carrier, and 17-meter span arrangement can be achieved.
本发明提供本发明涉及一种用于地铁明挖基坑扩大端的施工便桥结构，包括钢便桥结构，所述钢便桥结构由多个单榀钢便桥拼接形成，所述单榀钢便桥包括工字钢、钢顶板以及钢腹板，所述钢顶板设置两个且分布在所述钢腹板的两端，所述工字钢设置在两个所述钢顶板之间；单榀钢便桥拼接件，用于与单榀钢便桥拼接；路面层，铺设在所述钢便桥结构上；抗滑墙，围设在所述钢便桥结构的外周。本发明通过采用上述结构，可降低因地铁基坑施工对周边交通环境的影响，解决地铁明挖基坑扩大端施工便道宽度不足问题，与传统混凝土盖板相比，具有造价低、材料可回收重复利用、同时利用钢结构作为便桥载体，可实现17米跨度布置。
