Existing pile static load test method and test device
The invention discloses an existing pile static load test method and test device, and belongs to the technical field of geotechnical engineering. The existing pile static load test method comprises the steps that a test pile is marked according to pile position coordinates; on the basis of the identification information, drilling is conducted downwards at the corresponding position of the center of the test pile till a test hole with the required depth is formed in the pile body of the test pile; a hard pipe is arranged in the test hole till the bottom of the hard pipe makes contact with the hole bottom of the test hole, the top end of the hard pipe is exposed out of the ground by a certain height, and a slurry through hole communicated with the test hole is formed in the pipe wall of the hard pipe; grouting materials are poured into the hard pipe and the test hole, and the test hole is filled with the grouting materials until the grouting materials overflow from a pipe opening in the top end of the hard pipe; the top end of the hard pipe is connected with a bearing plate, a jack and a counter-force system are installed, and a single-pile static load test is carried out. Under the condition that the existing pile is buried underground, the static load test can be conveniently carried out without excavation of the foundation pit, the test cost is saved, and the test time is shortened.
本申请公开了一种既有桩静载试验方法和试验装置，属于岩土工程技术领域。既有桩静载试验方法包括：根据桩位坐标对试验桩进行标识；基于标识信息，在试验桩的中心对应位置，向下钻孔直至在试验桩桩身形成达到要求深度的试验孔；在试验孔内置入硬管直至硬管的底部与试验孔的孔底接触，硬管的顶端露出地面一定高度，其中，硬管的管壁设置有与试验孔连通的通浆孔；在硬管和试验孔中灌注灌浆料，将试验孔充满，直至浆料从硬管的顶端管口溢出；在硬管的顶端连接承压板，安装千斤顶和反力系统，开展单桩静载试验。本申请在既有桩在埋设在地下的情况下，未经基坑开挖也能够方便地进行静载试验，节约试验费用，缩短试验时间。
