摘要
中心城区现状道路下方各类市政管线非常密集,而轨道交通站点基坑的大开挖施工范围内所有管线都需进行迁改,尤以大型排水管道的迁改最为复杂,且因涉及到临时排水,迁改费用通常较高.以上海市轨道交通14号线工程东新路站建设为例,结合轨交站点总体设计,在武宁路(凯旋北路-普雄路)对φ2400合流污水总管进行永久迁改,并对局部节点进行预加固和临时排水,确保轨交站点的顺利建设.
Various municipal pipelines under the existing roads in the central urban area are very dense,and all pipelines within the construction scope of the large excavation of the foundation pit of the rail transit station need to be relocated, especially the relocation of large-scale drainage pipelines is the most complicated, and because it involves the temporary drainage, the cost of relocation is usually higher.Taking the construction of Dongxin Road Station in Shanghai Rail Transit Line 14 Project as an example,combined with the overall design of the rail transit stations, the Φ2 400 combined sewage trunk pipe is permanently relocated on Wuning Road(North Kaixuan Road-Puxiong Road), and some The local nodes are pre-reinforced and temporarily drained to ensure the smooth construction of rail transit stations.
