Pier stud-cross beam-bent cap integrated public rail double-layer viaduct and construction method
The invention relates to a pier stud-cross beam-capping beam integrated public rail double-layer viaduct and a construction method. The construction method comprises the following steps: mounting an embedded adjusting bracket; hoisting a first section reinforcement cage of the pier column; pouring a bearing platform; pouring a lower pier column; the lower pier column and the track cross beam are integrally poured; pouring an upper pier column; and the upper pier column and the cover beam are integrally poured. The method has the beneficial effects that the mounting precision of the bottom of the first section reinforcement cage of the pier column is improved by pre-embedding the adjusting bracket, the #-shaped steel fixing frame and the positioning steel plate; the slurry leakage phenomenon of pier column concrete pouring is reduced through the sponge strips; the steel hoop is mounted on the steel pipe column through the bolt, so that the diagonal bracing connection efficiency between the column and the steel pipe is improved, and the damage of a welding joint to the steel pipe is reduced; a formwork supporting system composed of the steel pipe stand columns, the bailey beams, the formwork supporting trusses and the formworks is adopted to conduct formwork supporting on a rail cross beam and a cover beam, and traffic influences on an existing road are avoided. The pier column, the cross beam and the cover beam are integrally poured, seamless and durable.
本发明涉及一种墩柱‑横梁‑盖梁一体化公轨双层高架桥及施工方法，这种施工方法包括步骤：预埋调整托架安装；墩柱首节钢筋笼吊装；承台浇筑；下墩柱浇筑；下墩柱与轨道横梁一体化浇筑；上墩柱浇筑；上墩柱与盖梁一体化浇筑。本发明的有益效果是：通过预埋调整托架、#字型钢固定框架和定位钢板提高了墩柱首节钢筋笼底部的安装精度；通过海绵条减少了墩柱混凝土浇筑的漏浆现象；通过螺栓在钢管柱上安装钢抱箍，提高了柱钢管之间斜撑连接效率，且减少了焊结对钢管的损伤；采用钢管立柱+贝雷梁+支模桁架+模板组成的支模体系对轨道横梁及盖梁进行支模，避免了对既有道路的交通影响；墩柱与横梁、盖梁一体化浇筑，无接缝，经久耐用。
