Excavation and support method for foundation pit in shallow water sludge beach area
The invention discloses a shallow water silt beach area foundation pit excavation supporting method, and belongs to the technical field of foundation pit construction.A construction platform is built in shallow water of a beach, a supporting structure for foundation pit excavation is built on the construction platform, then a foundation pit is excavated under protection of the supporting structure, and bearing platform construction is conducted; and after the bearing platform is constructed, the foundation pit supporting structure is dismantled. The special geological and hydrological characteristics of the shallow water sludge beach are combined, the steel cofferdam and a supporting structure for excavation of the whole bearing platform foundation pit are constructed by using common profile steel and a common excavator, and the supporting structure is matched with the soil cofferdam in the beach, so that the investment of engineering funds is greatly reduced on the premise of playing a role in supporting the bearing platform foundation pit.
本发明公开了一种浅水淤泥海滩地区基坑开挖支护方法，属于基坑施工技术领域，通过在海滩浅水中构筑施工平台，并在施工平台上建立基坑开挖的支护结构，然后在支护结构的保护下开挖基坑并进行承台施工，待承台施工完成后拆除基坑支护结构。本发明结合浅水淤泥海滩特有的地质水文特点，通过使用普通型钢与普通挖掘机构建钢围堰以及整个承台基坑开挖的支护结构，并且与海滩中的土围堰相配合，在起到承台基坑支护作用的前提下，大幅减少工程资金的投入。
