Prestress monitoring method of existing anchor cable
The invention discloses a prestress monitoring method of an existing anchor cable. An outer anchor ring force transmission structure and an anchor cable prestress monitoring device are mainly adoptedto achieve the purpose of monitoring the prestress of the anchor cable in real time, the outer anchor ring force transmission structure comprises an outer anchor ring, bolt clamping pieces are inserted between the outer anchor ring and an existing anchor ring, and jacking devices are placed on the lower portion of the outer anchor ring. A jacking distance measuring instrument is fixed between theouter anchor ring and an anchor backing plate, prestress applied to the existing anchor ring can be effectively transmitted to the anchor cable prestress monitoring device through the outer anchor ring force transmission structure, accordingly, the prestress condition of the anchor cable is monitored in real time, and the device is simple, convenient to operate and low in cost. Especially the requirements for the shape of an existing anchor ring of an existing anchor cable and the exposed length of the anchor cable are low, no structural influence is generated on the existing anchor ring, thejacking devices and the jacking distance measuring instrument can be repeatedly used, and the use cost is saved.
本发明公开了一种既有锚索的预应力监测方法，主要采用外锚环传力结构和锚索预应力监测装置实现实时监测锚索预应力的目的，外锚环传力结构包括外锚环，外锚环与既有锚环之间插有插销夹片，外锚环下方安放有顶升装置，外锚环与锚垫板间固定有顶升距离测量仪器，通过外锚环传力结构可以将施加于既有锚环上的预应力有效传递给锚索预应力监测装置，从而实现对锚索预应力情况的实时监测，本发明设备简单，操作方便，成本低廉，特别对于既有锚索的既有锚环形状、锚索外露长度要求较低，又不会对既有锚环产生结构影响，并且其顶升装置和顶升距离测量仪器可以重复利用，节约了使用成本。
