双层钢桁梁桥面U肋集水槽施工技术

Construction Technology of U-rib Sink on Double-layer Steel Truss Bridge Surface

桥梁桥面排水系统有利用既有结构排水,也有在桥墩处设置竖向排水管排水,也有考虑到环境保护和危化泄漏等应急排水需配套设置事故应急池。依托跨水厂取水地景观桥赣州蟠龙大桥项目对钢结构桥梁纵向排水管道的设计、制造和施工进行研究,将排水管与结构融合,采用不锈钢U肋集水槽和不锈钢内衬保证耐久性、适用性和美观性。

The bridge deck drainage system uses the existing structure for drainage,also sets up vertical drainage pipes at the piers for drainage,and also takes into account that emergency drainage such as environmental protection and hazardous leakage needs to be equipped with an emergency pool.The design,manufacture and construction of the longitudinal drainage pipe of the steel structure bridge are studied based on the landscape bridge project of Ganzhou Panlong Bridge across the water intake site of the water plant.The drainage pipe is integrated with the structure,and the stainless steel U-ribbed catch basin and stainless steel lining are used to ensure durability,applicability and aesthetics.
