Device and method for detecting vertical bearing capacity of single pile of deep precast pile
The invention relates to the technical field of engineering pile bearing capacity detection, in particular to a deep precast pile single-pile vertical bearing capacity detection device and a detection method thereof.The deep precast pile single-pile vertical bearing capacity detection device comprises a pile pit formed in the ground, an engineering pile is arranged in the pile pit, and the deep precast pile single-pile vertical bearing capacity detection device is characterized in that a steel pipe with the two ends closed is arranged at the top end of the engineering pile. A positioning guide part is fixed to the periphery of a pile pit, then a steel pipe is arranged in the center of the positioning guide part, an end plate abuts against the top of an engineering pile, then buttresses and a bearing platform are erected on the periphery of the ground, a static load is erected on the top of the bearing platform, and the bottom of the bearing platform abuts against the top of the steel pipe; the hydraulic rod is controlled to carry out graded loading, the numerical values of the first displacement sensor and the second displacement sensor are recorded, the difference value, namely the sinking deformation amount of the pile foundation, is calculated, and the detection difficulty of the large-burial-depth precast pile can be solved by downwards inserting the arranged steel pipe into the burial-depth engineering pile.
本发明涉及工程桩承载力检测技术领域，具体涉及一种深层预制桩单桩竖向承载力检测装置及其检测方法，包括有开设在地面上的桩坑，所述桩坑内设置有工程桩，其特征在于，所述工程桩的顶端设置有两端封闭的钢管。本发明将定位导向部固定在桩坑的外周，然后将钢管置于定位导向部中心，并使端板与工程桩的顶部顶紧，之后在地面外周架设支墩和承重平台，使承重平台的顶部架设静载，并使承重平台的底部与钢管的顶部顶紧，控制液压杆进行分级加载，记录第一位移传感器和第二位移传感器的数值并计算其差值，即为桩基的下沉变形量，通过设置的钢管下插至埋深的工程桩上，能够解决埋深大的预制桩的检测难点。
