Post-construction anchor cable prestress detection coupling lengthening system and reinforcing method
The invention relates to the technical field of slope engineering, in particular to a post-construction anchor cable prestress detecting and reinforcing system for an anchoring engineering slope. According to the system, a clamping piece set and steel hoop combined novel structure can be adopted to integrally and stably clamp an existing working anchorage device, a hydraulic power system provides loads to pull a steel drawing rod, and the steel drawing rod sequentially drives a supporting cylinder, the steel hoop, a steel supporting ring and the clamping piece set to move together in a threaded screwing mode. The clamping piece set further fastens and clamps the working anchorage device to move synchronously, and then integral grading tensioning operation of the single anchor hole is achieved. According to the scheme, the defects that the exposed section of the post-construction anchor cable is insufficient in length and cannot be implemented, and an existing method is complex in process, low in work efficiency and the like are effectively overcome, and the post-construction anchor cable prestress detection coupling lengthening system and the reinforcing method which are easy and convenient to operate, rapid to implement and high in adaptability are established.
本申请涉及边坡工程技术领域，尤其涉及锚固工程边坡工后锚索预应力检测及补强系统。所述系统能够采用夹片组和钢套箍组合新型结构对既有工作锚具形成整体稳固夹持，液压动力系统提供载荷拉拽钢拉拔杆，钢拉拔杆通过螺纹旋接方式依次带动托缸、钢套箍、钢托环和夹片组一起移动，夹片组进一步紧固夹持工作锚具而同步移动，继而实现对单锚孔整体分级张拉操作。本方案有效克服了工后锚索外露段长度不足无法实施，以及现有方法工序较复杂且工效较低等痛点，建立了一种操作简便、快速实施、适应性强的工后锚索预应力检测耦合接长系统及补强方法。
