SMW piles, SMW pile supporting structures and SMW pile supporting structure construction method
The invention discloses SMW piles, SMW pile supporting structures and an SMW pile supporting structure construction method, and relates to the technical field of building deep foundation pit engineering. The piles comprise H-shaped steel, cement soil piles and arc-shaped steel sheets; the arc-shaped steel sheets are arranged on the outer sides of flange plates; the H-shaped steel is vertically arranged in the cement soil piles in the length directions of the flange plates; and the arc-shaped steel sheets are connected with enclosing purlins in a foundation pit, the enclosing purlins are connected into the foundation pit through supporting structures, and after small amount of cemented soil solidified bodies on outer side of H-shaped steel is stripped, the enclosing purlins can be tightly connected with the arc-shaped steel sheets and the H-shaped steel. According to the piles, the structure is simple and practical, the integrity of pile bodies of the SMW piles is ensured, the safety and stability of foundation pit supporting are enhanced, the risk of deformation and collapse is reduced, and the taken-down arc-shaped steel sheets can be repeatedly used, so that the cost is reduced,and the popularization and application value is achieved.
本发明公开一种SMW工法桩及其支护结构与施工方法，涉及建筑深基坑工程技术领域。包括H型钢、水泥土桩和圆弧形钢板，圆弧形钢板安装在翼缘板的外侧，H型钢沿着翼缘板的长度方向竖直安装在水泥土桩内，圆弧形钢板与基坑内的围檩相连接，围檩通过支撑结构连接在基坑内，在剥除H型钢外侧少量的水泥土固结体后，即可实现围檩与圆弧形钢板及H型钢紧密连接。本发明的结构简单实用，确保了SMW工法桩桩身的完整性,增强了基坑支护的安全稳定性、降低了变形坍塌的风险，取下的圆弧形钢板可重复使用，降低成本，具有推广应用价值。
