Vibro-replacement gravel pile in-situ shear test device
The invention discloses a vibro-replacement gravel pile in-situ shear test device which comprises a steel plate sleeve arranged at the top of a gravel pile in a sleeving mode; the jacking structure is pressed on the top surface of the gravel pile; the pressure applying module comprises a load oil cylinder and a base plate, and the load oil cylinder is transversely arranged and located between the base plate and the outer side wall of the steel plate sleeve; the lower end of the supporting module is inserted into the bottom face of the detection foundation pit, the upper end of the supporting module is inserted into the ground, the base plate is arranged on the side, facing the gravel pile, of the supporting module, and one side of the jacking structure is located at the top of the supporting module. The base plate is arranged on the side, facing the gravel pile, of the supporting module, the lower end of the supporting module is inserted into the bottom face of the detection foundation pit, the upper end of the supporting module is inserted into the ground, the base plate can be reliably installed and fixed in the detection foundation pit, and the situation that the base plate moves backwards relative to the gravel pile when a load oil cylinder works is avoided; the mounting stability of the base plate and the load oil cylinder is improved.
本发明公开了一种振冲碎石桩原位剪切试验装置，包括：钢板套，套设于碎石桩的顶部；顶压结构，压设于碎石桩的顶面；施压模组，包括载荷油缸和垫板，载荷油缸横向布置并位于垫板与钢板套的外侧壁之间；支撑模组，下端插设于检测基坑的底面，上端插设于地面，垫板设置于支撑模组朝向碎石桩的一侧，且顶压结构的一侧位于支撑模组的顶部。通过将垫板设置于支撑模组朝向碎石桩的一侧，且支撑模组的下端插设于检测基坑的底面，支撑模组的上端插设于地面，可将垫板可靠安装固定于检测基坑内，避免载荷油缸工作时发生垫板相对碎石桩后移的情况，提高垫板和载荷油缸的安装稳定性。
