格栅式水泥搅拌桩止水帷幕结合管井群深基坑支护降水施工技术

Dewatering Construction Technology of Deep Foundation Excavation Support of Grille Type Cement Stiring Pile Water-resisting Curtain Combined with Tube Well

结合北海市侨港镇公共租赁住房工程的深基坑支护及降水施工,针对该项目超厚软弱淤质土层及地下承压水位高等不利条件,提出了以格栅式水泥搅拌桩重力式止水帷幕作为基坑支护及隔水措施,基坑内设置管井群降水综合施工方法,并对该方法的关键施工工艺和技术要点进行了阐述。

In this paper,combined with the passengers Qiaogang Town public rental housing project of deep foundation excavation supporting construction,and precipitation for the project of super thick soft silt soil layer and underground pressure level higher adverse conditions,it puts forward taking cement mixing pile gravity grille type curtain of cut off water as foundation excavation supporting,and setting wells in the foundation excavation for dewatering. Meanwhile,the key construction technology and technique joints are described.
