Building foundation pile self-balancing static load test device and test method
The invention relates to a building foundation pile self-balancing static load test device and a test method, and relates to the technical field of foundation pile tests. Comprising two reinforcement cages and a load box welded to the opposite sides of the two reinforcement cages, the load box comprises a top cover and a bottom cover, and reinforcing parts for reinforcing the connection stability between the reinforcement cages and the load box are arranged on the opposite sides of the top cover and the bottom cover; a movable unit for uniformly stirring concrete slurry when the concrete slurry is injected into the reinforcement cage is further arranged on the reinforcing part; a displacement regulation and control unit for accurately controlling the displacement distance between the top cover and the bottom cover is further arranged between the top cover and the bottom cover of the load box; the problem that the step-by-step loading distance of the load box is delayed can be solved through the displacement regulation and control unit, the situation that the step-by-step loading distance of the load box is too large is avoided, the step-by-step loading distance of the load box can be accurately controlled, and the accuracy of a foundation pile self-balancing static load test is improved.
本发明涉及一种建筑基桩自平衡静载试验装置及试验方法，且涉及基桩试验的技术领域；包括两钢筋笼以及两钢筋笼相对侧焊接的荷载箱，荷载箱包括顶盖及底盖，顶盖以及底盖相背侧设有加固钢筋笼与荷载箱之间连接稳定性的加固部件，加固部件上还设置有往钢筋笼内注入混凝土浆料时对混凝土浆料进行均匀搅拌的活动单元，荷载箱的顶盖以及底盖之间还设置有对顶盖和底盖之间位移的距离进行精准控制的位移调控单元；本发明通过位移调控单元单元能解决荷载箱逐级加载距离出现延迟的问题，避免荷载箱逐级加载的距离出现偏大的情况，而且还能够精准控制荷载箱逐级加载的距离，提高基桩自平衡静载试验的准确性。
