Earth cutting construction method for soft soil deep foundation pit
The invention provides an earth cutting construction method for a soft soil deep foundation pit. The earth cutting construction method comprises the following steps that a, dividing sequence excavation zones; b, determining an excavation sequence and a flow direction; c, arranging temporary construction roads; and d, carrying out excavation operation. The method has the advantages that the foundation pit is excavated to the end at a time, layered excavation is not needed, working efficiency can be improved, and cost is saved; sequence earth cutting is carried out, the side pressure of the foundation pit is released regionally, the foundation pit excavation is safer, foundation pit side wall supporting measures such as anchor cables can be reduced to a certain extent, the design is optimized, and the construction progress is accelerated; sequence earth cutting is adopted, a basement structure is also poured in a sequence mode, and a water stop steel plate on one side of a post-cast strip and scabbling cost can be saved; the temporary construction roads and construction sequences are reasonably designed, and replacement of the construction roads is reduced.
本发明提出一种软土深基坑挖土施工工法，包括如下步骤：a，划分跳仓开挖分区；b，确定开挖顺序及流向；c，布置临时施工道路；d，开挖作业。本发明的优点：基坑开挖一次到底，无需分层开挖，可提高工作效率，节约成本；跳仓挖土，分块释放基坑侧压力，基坑开挖更安全，在一定程度上还可以减少锚索等基坑侧壁支护措施，优化设计，加快施工进度；采取跳仓挖土，地下室结构也是跳仓浇筑，可省去后浇带一侧的止水钢板及凿毛费用；合理设计临时施工道路和施工顺序，减少施工道路的换填。
