Underground pile foundation static load test structure and construction method thereof
The invention discloses an underground pile foundation static load test structure and a construction method thereof.The underground pile foundation static load test structure is used for conducting an underground pile foundation static load test and arranged on the ground, a first containing hole is formed in the ground, and the bottom face of the first containing hole is located at the preset elevation position; the underground pile foundation static load test structure comprises a test pile and a first pile casing. The test pile comprises a pile foundation and an extension section, the pile foundation is buried in the land, the whole pile foundation is located below the first containing hole, the top of the pile foundation is located at the preset elevation position, one end of the extension section is located in the first containing hole and connected to the top, and the other end of the extension section extends from the interior of the first containing hole to protrude out of the ground; the first pile casing is at least partially arranged in the first containing hole, the first pile casing is arranged on the periphery of the extension section in a sleeving mode, and a cavity is formed between the casing wall of the first pile casing and the extension section, so that friction force between the extension section and soil is eliminated, and the accuracy of test data of a static load test conducted on the pile foundation integrally located underground is improved.
本发明公开了一种地下桩基静载荷试验结构及其建造方法，该地下桩基静载荷试验结构用于进行地下桩基静载荷试验，且设于地面，地面设有第一容置孔，第一容置孔的底面位于预定标高位置，该地下桩基静载荷试验结构包括试验桩以及第一护筒。试验桩包括桩基以及延长段，桩基埋设于土地，桩基整体位于第一容置孔下方，且桩基的顶部位于预定标高位置，延长段的一端位于第一容置孔内且连接于顶部，延长段的另一端自第一容置孔内延伸至凸出于地面，第一护筒至少部分设置于第一容置孔内，且第一护筒套设于延长段的外周，第一护筒的筒壁与延长段之间形成空腔，从而消除延长段与土壤之间的摩擦力，提升对整体位于地下的桩基进行静载荷试验的试验数据准确性。
