通过对箱梁顶板波纹管施工控制点的分析,确保波纹管通畅、不受损。在桥梁施工中,箱梁顶板波纹管的安装、定位、保护通常不被重视,一些施工单位在现场施工时往往由于对现场施工工人缺少技术交底,致使工人在安装波纹管时不够精心,在浇筑波纹管时随意踩踏,造成波纹管施工中存在质量缺陷。但如果发生漏浆,由于孔道堵塞将给钢绞线穿束造成极大困难,进而导致施工难度加大。笔者结合徐州丰县复新河大桥、丰沛运河崔楼大桥两座桥梁波纹管的施工控制谈几点做法,以保证箱梁波纹管通畅、不受损。
Through the box girder roof bellows construction control point analysis to ensure that the bellows smooth, undamaged. In the bridge construction, the installation, positioning and protection of corrugated pipe on the roof of box girder are usually not taken seriously. Some construction units often lack the technical explanation for on-site construction workers due to the lack of technical explanation for the construction workers. As a result, workers are not careful enough in installing corrugated pipe. Corrugated pipe stampede, resulting in corrugated pipe construction quality defects. However, if leakage occurs, it will be extremely difficult for the strand to pass through due to the blockage of the hole, which will further increase the construction difficulty. The author combines Xuzhou Fengxian Fusuhe Bridge, Fenglei Bridge Cui Lou Bridge two bridge bellows construction talk about several practices to ensure that the box beam bellows smooth, undamaged.
