Uplift pile uplift force detection method
The invention discloses an uplift pile uplift force detection method. A detection device comprises an uplift pile, a steel plate, a force transmission member and a test beam, wherein the uplift pile is poured in a pile hole, a plurality of main reinforcements exposed out of the upper end of the uplift pile are arranged in the uplift pile, a hooking and pulling member is welded to one end, exposedout of the uplift pile, of each main reinforcement, the two ends of the force transmission member are detachably connected with the bottom face of the test beam and the top face of the steel plate respectively, the test beam is placed on supporting piers and separated from the ground outside the pile hole at intervals, a jack for applying pile pulling force to the uplift pile is arranged between the test beam and the ground, and the uplift pile is hung on the steel plate through the hooking and pulling members. During construction, a perfect detection state that the upper non-effective pile length is a hollow pile is reserved, and the problem that the negative friction resistance of the non-effective pile length influences a detection result is effectively solved; and meanwhile, the recyclable force transmission member is adopted for detecting the pulling resistance of the effective pile length, compared with an existing solution in the market, construction is convenient, the engineering cost can be greatly saved, and pile body filling materials in an empty hole area are effectively saved.
本发明公布了一种抗拔桩抗拔力检测方法，检测装置包括抗拔桩、钢板、传力构件、试验梁，所述抗拔桩浇筑于桩孔中，抗拔桩内布置有露出抗拔桩上端的多根主筋，主筋露出抗拔桩的一端焊接有钩拉构件，传力构件的两端分别与试验梁的底面及钢板的顶面可拆卸连接，试验梁被搁置在支撑墩上与桩孔外的地面间隔隔开，试验梁与地面之间设有对抗拔桩施加拔桩力的千斤顶，抗拔桩通过钩拉构件悬挂在钢板上。施工时保留了上部非有效桩长为空孔桩的完美检测状态，有效解决了非有效桩长的负摩阻力影响检测结果问题；同时采取可回收的传力构件进行有效桩长的抗拔力检测，相比于市场现有解决方案施工便利、可极大的节约工程造价而且有效节约了空孔区桩身填充材料。
