Single-pile built-in horizontal static load test method and device
The invention relates to the technical field of building construction, in particular to a single-pile built-in horizontal static load test method and device, and the method comprises the following steps: arranging a counter-force buttress, placing a steel roller at the upper part of the counter-force buttress, placing a steel truss at the upper part of the steel roller, fixedly connecting the other end of the steel truss with a clamping device through an anchor bolt, and padding a steel plate in the middle; pre-clamping the clamping device, and pushing a jack in the device to the periphery of the test pile; the single-pile built-in horizontal static load test method and device have the beneficial effects that the pile top is limited through the steel truss and the clamping device, and the built-in state of the pile top in actual engineering is simulated. In order to ensure firm connection between the steel truss and the pile top and effective exertion of the embedding effect of the pile top in the test process, the steel truss and the test pile are connected through a clamping device, jacks are arranged in the clamping device, each jack acts on the outer surface of the test pile in an equal stress mode in the use process, and clamping is gradually firm.
本发明涉及建筑施工技术领域，具体为一种单桩嵌固式水平静载试验方法及装置，包括以下步骤：设置反力支墩，反力支墩上部放置钢滚轴，钢滚轴上部放置钢桁架，钢桁架另一端用锚栓固定连接夹紧装置，中间垫钢板；将夹紧装置预夹紧，装置内部的千斤顶顶推至试桩周边；有益效果为：本发明提出的单桩嵌固式水平静载试验方法及装置，通过钢桁架及夹紧装置对桩顶进行限制，模拟桩在实际工程中桩顶的嵌固状态。为保证试验过程中钢桁架与桩顶连接牢固，及桩顶嵌固效果的有效发挥，钢桁架与试桩之间采用夹紧装置连接，夹紧装置内部设置千斤顶，使用过程中每个千斤顶等应力作用于试桩外表面，逐渐夹紧牢固。
