Reverse construction method for underground comprehensive pipe gallery
The invention discloses a reverse construction method for an underground comprehensive pipe gallery. According to the reverse construction method, a vertical wall is constructed firstly, then a top plate is constructed in batches, specifically, part of the top plate is constructed firstly, then an internal soil body is excavated, all the top plate is constructed, then a bottom plate is constructed, and finally internal construction design of the pipe gallery is conducted. According to the method, the construction technology is simplified, foundation pit protection is not needed, and the foundation pit excavation volume is greatly reduced; the construction period is effectively shortened by means of segmented simultaneous construction, the top plate can be used as a stacking site of excavated soil, and the influence on traffic and buildings around the construction site is reduced; the construction is carried out in a closed underground environment, so that the construction difficulty increase and the prolonged construction period caused by the influence from climatic factors are avoided; and meanwhile, an underground diaphragm wall is used as the side wall of the pipe gallery, so that a structural outer wall does not need to be built while soil retaining and water stopping are achieved, the construction cost of a project is reduced, obvious social and economic benefits are achieved, and the construction method is particularly suitable for construction of the comprehensive pipe gallery under urban roads with busy traffic.
本发明公开了一种地下综合管廊的逆序施工方法，本发明先施工竖墙，再对顶板进行分批施工，其中先施工部分顶板再进行内部土体开挖并完成所有顶板施工，接着进行底板施工，最后进行管廊内部施工设计。本发明简化了施工工艺，无需基坑防护，大大减小了基坑开挖量；利用分段同时施工有效缩短了施工工期，且顶板可做开挖土的堆放场地，减少对施工地点周围交通和建筑物的影响；本发明在地面以下的闭合环境内部进行施工，避免了气候因素影响所导致施工难度增加和工期延长；同时利用地下连续墙作为管廊侧墙，起到挡土和止水同时无需修筑结构外墙，降低了工程造价成本，具有明显的社会经济效益，尤其适用于交通繁忙的城市道路下综合管廊的施工。
