厦门高集海堤开口改造工程初步设计阶段保留了原高集海堤的DN1 200 mm给水原水管道,要求给水管仍随新建桥梁敷设通过。由于该给水管的管径较大,在实际设计过程中管道与桥梁结构发生了冲突,同时给水管道为压力管道,大管径压力管道随桥敷设有一定的安全隐患。本文对DN1 200mm给水原水管道随桥敷设的问题从各方面加以探讨研究,对给水管道随桥敷设跨海方案的制定具有借鉴意义。
The initial design phase of Xiamen Gaoji Dike Rebuild Project retained the DN1 200 mm raw water supply pipe of the original Gaoji Seawater Diy, and the water supply pipe was still required to be laid through the new bridge. Due to the large diameter of the water supply pipe, the pipe and bridge structure collide in the actual design process. Meanwhile, the water supply pipe is a pressure pipe, and the large diameter pressure pipe is laid with a certain safety hazard along the bridge. In this paper, DN1 200mm raw water supply pipe with the laying of the bridge problems to be explored from all aspects of the water supply pipe with the laying of the bridge across the sea plan for reference.
