Foundation pile horizontal bearing capacity detection test method and device
The invention relates to the technical field of building construction, in particular to a foundation pile horizontal bearing capacity detection test method and device.The foundation pile horizontal bearing capacity detection test method comprises the following steps that a counter-force beam abuts against one side of an anchor pile, a jack is placed at the other end of the counter-force beam, the jack abuts against a test pile, the jack is pre-loaded, it is ensured that the device is firmly installed, and the jack provides horizontal static load, namely horizontal thrust; the monitoring end of the dial indicator leans against the other side of the test pile, the dial indicator is firmly connected with the datum beam, and the datum pile is anchored on the ground for limiting and fixing the datum beam; the foundation pile horizontal bearing capacity detection test method and device have the beneficial effects that the characteristics of horizontal stress of the pile foundation under the actual working condition can be effectively reflected by applying a vertical load to the test pile, simulating the gravity of an upper building on the pile foundation and performing a single-pile horizontal static load test under the condition; in order to ensure that the vertical load acting force coincides with the axis of a test pile in the test process, the error of a test result caused by bending moment caused by vertical load eccentricity is avoided.
本发明涉及建筑施工技术领域，具体为一种基桩水平承载力检测试验方法及装置，包括以下步骤：将反力梁紧靠在锚桩一侧，反力梁另一端放置千斤顶，千斤顶顶靠在试桩上，千斤顶预加载，确保装置安装牢靠，千斤顶提供水平静载，即水平推力；百分表监测端靠在试桩另一侧，百分表与基准梁连接牢固，基准桩锚固在地面，用来限制固定基准梁；有益效果为：本发明提出的基桩水平承载力检测试验方法及装置，通过对试桩施加竖向荷载，模拟桩基受到上部建筑物的重力，在该条件下的单桩水平静载试验，可以有效反映桩基在实际工作条件下水平受力的特性；为保证试验过程中竖向荷载作用力与试桩轴线重合，避免竖向荷载偏心引起的弯矩对试验结果产生误差。
