Uplift pile and uplift static load test method thereof
The invention relates to an uplift pile and an uplift static load test method thereof, and relates to the technical field of foundation pile detection. An uplift pile comprises a pile body and a grouted core located in the pile body. The pile body is provided with a bearing plate, and the upper surface of the bearing plate abuts against the lower end wall of the pile body or/and the lower end wall of the grouted core. The bearing plate is connected with a lifting piece, and the end, away from the bearing plate, of the lifting piece extends upwards from the interior of the grouted core to the exterior of the upper end of the pile body. The bearing plate is provided with an installation hole in a penetrating mode in the thickness direction of the bearing plate, and the lifting piece can penetrate through the installation hole and is provided with a fixing piece used for abutting against the lower surface of the bearing plate. The upper end of the lifting piece is used for being connected with a building at the upper end of the pile body. During construction, the upper end of the lifting piece is connected with a building at the upper end of the pile body; the bearing plate is matched with the fixing piece and the lifting piece, so that the pile body or the grouted core can be integrally pressed, the whole and the grouted core can be integrally stressed, and the ultimate bearing capacity of a single pile of the uplift pile is increased.
本申请涉及一种抗拔桩及其抗拔静载荷试验方法，涉及基桩检测技术领域；一种抗拔桩，包括桩体和位于桩体内的灌芯；所述桩体设置有承接板，所述承接板的上表面与桩体的下端壁或/和灌芯的下端壁抵接；所述承接板连接有提拉件，所述提拉件的远离承接板的一端由灌芯内向上延伸至桩体的上端的外部；所述承接板沿自身厚度方向贯穿设置有供提拉件穿设的安装孔，所述提拉件设置有用于与承接板的下表面抵接的固定件；所述提拉件的上端用于与桩体上端的建筑相连。施工时，将提拉件的上端与桩体的上端的建筑相连；承接板与固定件、提拉件相互配合，有利于使桩体或灌芯整体受压，从而便于使整体及灌芯整体受力，以增大抗拔桩的单桩极限承载力。
