Device for testing bearing capacity of pile end of prestressed pipe pile
The invention discloses prestressed pipe pile end bearing capacity testing equipment, and relates to the technical field of prestressed pipe pile detection, and the prestressed pipe pile end bearing capacity testing equipment comprises an upper side prestressed pipe pile, an end prestressed pipe pile, a load box, a telescopic positioning mechanism, a supporting table and a material injection mechanism; the upper side prestressed pipe piles are multiple prestressed pipe piles distributed in the axial direction, threaded end discs are fixed to the two ends of each prestressed pipe pile, the threaded end discs at the ends of the adjacent prestressed pipe piles are connected through bolts and end nuts, an upper base plate is fixed to the threaded end disc at the lower end of the prestressed pipe pile on the lowermost side, and a lower base plate is fixed to the threaded end disc at the lower end of the prestressed pipe pile on the lowermost side; the inner ring edge of the upper seat plate is bent and extends upwards, an insertion hole is formed in the side wall of the top end of the upper seat plate, a shaft hole is formed in the horizontal part of the upper seat plate, a guide rod is arranged in the shaft hole, and the guide rod is parallel to the center line of the prestressed pipe pile; according to the prestressed pipe pile end bearing capacity testing equipment, the load box can be repeatedly used, meanwhile, gaps of the test pile are filled, the test pile can be continuously used as an engineering pile, and the cost is reduced.
本发明公开了一种预应力管桩桩端承载力测试设备，涉及预应力管桩检测技术领域，包括上侧预应力管桩、端头预应力管桩、荷载箱、伸缩定位机构、支撑台和注料机构；上侧预应力管桩：为多根轴向分布的预应力管桩，每根预应力管桩的两端均固定有螺纹端盘，相邻的预应力管桩端部的螺纹端盘通过螺栓和端头螺母进行连接，最下侧的预应力管桩下端的螺纹端盘上固定有上座板，所述上座板的内环边缘向上弯折延伸，其顶端侧壁设有插孔，所述上座板的水平部分设有轴孔，该轴孔内设有导向杆，所述导向杆平行于预应力管桩的中心线；本预应力管桩桩端承载力测试设备，荷载箱可以重复使用，同时试桩的缝隙被填补，可继续作为工程桩使用，降低了成本。
