Detachable settlement observation device for single-pile static load test and installation method
The invention provides a detachable settlement observation device for a single-pile static load test and an installation method, and belongs to the technical field of foundation pile detection, and the detachable settlement observation device for the single-pile static load test comprises a jack, a jack base plate, a displacement point fixing element, a reference pile, a telescopic reference beam, a sensor support and a sensor. The design of the displacement point fixing element solves the problems of resource waste and construction period waste caused by the fact that a pile cap needs to be manufactured or a steel casing needs to be machined, random spot check can be achieved, project detection data are accurate, and project quality safety is greatly improved. The sensor bracket is formed by connecting a plurality of bracket plates, so that the weight is reduced, the influence on a test result is reduced, and the problem that the suction force of the magnetic gauge stand is weakened along with time is solved. A rubber gasket is arranged on the inner wall of the sensor support, friction force between the sensor support and the telescopic datum line beam can be increased, and the problem that the sensor slides due to splashing leakage of hydraulic oil is avoided. And the datum line beam is telescopic, so that transportation and carrying are convenient.
本发明提供了一种单桩静载试验可拆卸式沉降观测装置及安装方法，属于基桩检测的技术领域，单桩静载试验可拆卸式沉降观测装置包括千斤顶、千斤垫板、位移点固定元件、基准桩、可伸缩基准梁、传感器支架和传感器。位移点固定元件的设计解决了需要制作桩帽或加工钢护筒引起的资源浪费和工期浪费的问题，可实现随机抽检，工程检测数据准确，大大提高了工程质量安全。传感器支架采用多块支架板连接而成，减轻了重量，减小了对试验结果的影响，解决了磁性表座的吸力随时间削弱的问题。传感器支架的内壁设置橡胶垫片，可增大与可伸缩基准梁之间的摩擦力，避免因液压油溅漏导致传感器滑动的问题。基准梁的可伸缩设计，便于运输携带。
