Temporary bailey bridge for excavation of basement foundation pit and installation method of temporary bailey bridge
The invention discloses a temporary bailey bridge for basement foundation pit excavation and an installation method of the temporary bailey bridge. The bailey bridge comprises trestle sections arranged between underground structures of all layers and profile steel platforms arranged at the two ends of the trestle sections. The trestle section comprises a bridge deck system, bailey beams arranged on the two sides of the bridge deck system, steel corbels installed on the basement independent columns and bearing cross beams arranged on the steel corbels, and the two ends of each bailey beam are connected with the bearing cross beams correspondingly. The bridge deck system comprises a plurality of main cross beams arranged at intervals, a plurality of secondary longitudinal beams arranged on the main cross beams and bridge decks laid on the secondary longitudinal beams, and the two ends of the main cross beams are connected with the bailey beams respectively; the profile steel platform comprises a steel corbel installed on the main body structure column, a bearing cross beam arranged on the steel corbel, an I-shaped steel longitudinal beam laid on the bearing cross beam and a steel plate laid on the I-shaped steel longitudinal beam. The assembly type bailey bridge structure is formed by matching the bailey beams with the steel plates, the cross beams, the basement independent columns and other components, assembly and disassembly are convenient, and the working procedure is simple.
本发明公开了一种地下室基坑开挖用临时贝雷桥及其安装方法，贝雷桥包括设置在每层地下结构间的栈桥段和设置在栈桥段两端的型钢平台，栈桥段包括桥面系、设置在桥面系两侧的贝雷梁、安装在地下室独立柱上的钢牛腿和设置在钢牛腿上的承重横梁，所述贝雷梁的两端分别与承重横梁连接；桥面系包括间隔设置的多道主横梁、设置在主横梁上的多道次纵梁以及铺设在次纵梁上的桥面板，主横梁两端分别与贝雷梁连接；型钢平台包括安装在主体结构柱上的钢牛腿、设置在钢牛腿上的承重横梁、铺设在承重横梁上的工字钢纵梁以及铺设在工字钢纵梁上的钢板。本申请通过贝雷梁配合钢板、横梁和地下室独立柱等构件形成装配式贝雷桥结构，安拆方便，工序简单。
