Steel pipe pile and cement-soil mixing pile combined supporting structure and construction method thereof
The invention discloses a steel pipe pile and cement-soil mixing pile combined supporting structure and a construction method thereof. The structure comprises a supporting assembly and a reinforcing assembly. The supporting assembly is formed by connecting a plurality of steel pipe piles in parallel, the bottom of the supporting assembly is vertically anchored into a hard soil layer to be fixed, the reinforcing assembly is formed by overlapping a plurality of cement-soil mixing piles, and the reinforcing assembly is fixedly connected with a part of the supporting assembly exposed out of the hard soil layer. The method comprises the steps that cement-soil mixing pile construction is conducted in a construction area, and the cement-soil mixing piles are in lap joint with one another to form the reinforcing assembly; before hardening of the cement-soil mixing piles, the steel pipe piles are driven one by one along the boundary of the supporting structure, the steel pipe piles penetrate through the rear bottom ends of the cement-soil mixing piles to be anchored into the hard soil layer, and every two adjacent steel pipe piles are fixedly connected; and after the strength of pile bodies of the cement-soil mixing piles meets the strength requirement, a foundation pit or a harbor basin is excavated in a layered mode. The horizontal bearing capacity and integrity of the supporting structure can be effectively improved, and the supporting structure is safe, economical and reliable.
本发明公开了一种钢管桩与水泥土搅拌桩组合支护结构及其施工方法，结构包括支撑组件和加固组件；支撑组件由若干钢管桩并列连接构成，支撑组件的底部竖直锚入硬土层中固定，加固组件由若干水泥土搅拌桩互相搭接构成，加固组件与支撑组件露出硬土层的部分固定连接。方法包括：在施工区域内进行水泥土搅拌桩施工，并使各水泥土搅拌桩互相搭接构成加固组件；在水泥土搅拌桩硬结前，沿支护结构的分界线逐根打入钢管桩，使钢管桩贯穿水泥土搅拌桩后底端锚入硬土层，并且将相邻两钢管桩连接固定；待水泥土搅拌桩桩身强度满足强度要求后，分层开挖基坑或港池。本发明能有效提高支护结构的水平承载力及整体，既安全又经济可靠。
