Existing old small bridge and culvert corrugated steel reinforcing construction method
The invention discloses an existing old small bridge and culvert corrugated steel reinforcing construction method. The method comprises the steps: S1, carrying out on-site survey setting-out; S2, carrying out corrugated steel component manufacturing and entry inspection; S3, excavating the foundation of the old small bridge; S4, constructing a solid wall type abutment on the foundation;S5, pre-burying channel steel connecting pieces on the top surface of the foundation or the abutment;S6, carrying out corrugated steel plate piece assembling and arch installation; S7, carrying out anticorrosivecoating on the inner side of the corrugated steel plate on site; and S8, filling the space between the corrugated steel plate arch and the original bridge with concrete. The method has the advantagesof being safe and rapid in construction, short in construction period, environmentally friendly in construction, low in construction cost, remarkable in benefit, capable of effectively solving the problem that diseases are gradually generated in the using process of existing old small bridges and culverts and the like.
本发明公开了一种现役旧小桥涵波纹钢加固施工方法，包括S1：现场测量放样；S2：波纹钢构件制造及进场检查；S3：旧小桥的基础开挖处理；S4：基础上实体墙式桥台施工；S5：基础或桥台顶面槽钢连接件预埋；S6：波纹钢板件拼装栱安装；S7：波纹钢板内侧现场防腐涂装；S8：波纹钢板栱与原桥之间混凝土注填；采用该方法施工安全快捷、施工作业工期短、施工环保、工程造价低、效益显著，可有效解决现役旧小桥涵使用过程中逐步产生的病害问题等优点。
