无锡市地铁1号线工程沿蠡湖大道DN2200浑水管迁改方案研究

Study of DN2200 Muddy Water Pipe Removal Reconstruction Scheme for Wuxi Metro Line 1 Project along Lihu Avenue

无锡市地铁1号线工程在线路南端主要沿蠡湖大道呈南北走向,位于道路东侧的绿化带内。针对线路基本处于与现状DN2200浑水管平行且位于其下方设置的状况,沿蠡湖大道设置的车站及区间施工都要对该浑水管产生不同程度的影响,该文介绍了沿蠡湖大道DN2200浑水管的迁改方案(整体迁改和局部迁改),并对两种迁改方案作了经济技术比较,还对方案的选择提出了建议。

Wuxi Metro Line 1 Project presents the south-north alignment mainly along Lihu Avenue at the south end of the line, and is located within the greening belt at the east side of the avenue. Aiming at the line basically being paralleled with the existing DN2200 muddy water pipe and being at its lower position, the construction of stations and the areal construction along Lihu Avenue will always produce the different levels of influence on the muddy water pipelines. The article introduces the DN2200 muddy water pipeline removal and reconstruction schemes along Lihu Avenue (integrated removal reconstruction and partial removal reconstruction), compares the economy and technology of two removal and reconstruction schemes, and puts forward the proposal for the selection of scheme.
