Reverse construction method for water-rich deep foundation pit sump
The invention relates to the field of deep foundation pit sump construction, in particular to a reverse construction method for a water-rich deep foundation pit sump. The problem that the construction progress is affected by water gushing and sand gushing at the bottom of a foundation pit is solved. The reverse construction method for the water-rich deep foundation pit sump comprises the following steps of (1) carrying out construction preparation; (2) excavating a base earthwork; (3) constructing side walls and bottom plates of a straight section and a climbing section; (4) reinforcing the sump; and (5) constructing the sump. Compared with a traditional freezing method for sequentially constructing the sump, the reverse construction method for the water-rich deep foundation pit sump has the advantages that selection is convenient, construction teams are popularized, the construction threshold is low and the like, the construction speed is greatly increased, the construction period is effectively guaranteed, the construction efficiency is high, and manpower and material resources which are comprehensively input are saved; compared with the freezing method for sequentially manufacturing the sump, a large amount of machine team cost, labor cost and scaffold renting cost are saved, and the risk of base inrush is effectively reduced; meanwhile, reference significance is provided for construction of other subway stations under the working conditions of sand gushing, water gushing and the like of a sump base.
本发明涉及深基坑集水坑施工领域，具体是一种富水深基坑集水坑逆作施工方法，解决了基坑底涌水、涌砂影响施工进度的难题。包括以下步骤：㈠施工准备；㈡开挖基底土方；㈢施工平直段、爬坡段的侧墙及底板；㈣加固集水坑；㈤施工集水坑。发明所述富水深基坑集水坑逆作施工方法，相比于传统方法冷冻法顺做集水坑，具有选用方便，施工队伍普及、施工门槛低等优点，大幅加快了施工速度，有效保障了工期，施工效率高，综合投入的人力、物力较为节约。相比于冷冻法顺做集水坑，节省大量机械的台班费、人工费和脚手架租赁费，有效降低基底突涌的风险。同时对于集水坑基底涌砂、涌水等工况，对其他地铁站施工具有借鉴意义。
