Combined type foundation pit supporting pile
The invention discloses a combined type foundation pit supporting pile, and belongs to the technical field of foundation pit supporting. The combined type foundation pit supporting pile comprises a steel latticed column, a precast pile and a high-pressure jet grouting pile, the steel latticed column is provided with a latticed column split body, the latticed column split body comprises a lower column body, an upper column body and a radial locking structure, wherein the lower column body is provided with a containing cavity, the groove wall of the containing cavity is provided with a coupling groove, and a spring is placed in the containing cavity; the edge of the bottom of the upper column body axially extends to form a coupling part, and the bottom surface of the upper column body is supported at the step of the containing cavity; and the radial locking structure comprises a first locking piece and a second locking piece which are matched in a wedge shape, the radial locking structure is provided with a first station and a second station, the radial locking structure is located in the groove wall of the containing cavity at the first station, the top of the first locking piece abuts against the top wall of the coupling groove, the bottom of the second locking piece is connected to the top of the spring in a pressing mode, and the coupling part stops the first locking piece from being unlocked in the radial direction. When a foundation stratum is supported to move downwards, the latticed column split body can stretch and still maintain certain supporting force, and the beneficial effect of being high in supporting safety is achieved.
本发明公开了一种复合式基坑支护桩，属于基坑支护技术领域，本发明包括钢格构柱、预制桩、高压旋喷桩，钢格构柱设置有格构柱分体，格构柱分体包括：下柱体，其上设置有容置腔，容置腔的槽壁上设置耦合槽，容置腔内放置有弹簧；上柱体，其底部边缘处轴向延伸有耦合部，其底面支撑于容置腔的阶梯处；径向锁止结构，包括楔形配合的第一锁止件和第二锁止件，径向锁止结构具有第一工位和第二工位，在第一工位，径向锁止结构位于容置腔的槽壁中，第一锁止件的顶部抵接耦合槽的顶壁上，第二锁止件的底部压接于弹簧的顶部，耦合部阻挡第一锁止件径向解锁；本发明在支撑基础地层下移时格构柱分体可以伸展且仍旧维持一定的支撑力，支护安全性高的有益效果。
