Background technology
In building trade, particularly in the hydraulic architecture industry, the application of prestress anchorage cable is extremely extensive.Traditional prestress anchorage cable generally is divided into tension type prestress anchorage cable and pressure-type prestress anchorage cable: the anchoring section leading portion of tension type prestress anchorage cable is stressed to be the tensile stress concentration zones, gradually to back segment and the easy shear failure that produces; The anchoring section latter end of pressure-type prestress anchorage cable is stressed to be the compressive stress concentration zones, gradually to leading portion and be prone to cause pressure break.
Above-mentioned two kinds of prestress anchorage cables are different to the failure mode of anchoring section; But all can have a strong impact on the effect of prestress anchoraging; If can not monitor the anchored force and the duty of anchor cable in real time, faults such as the not enough and anchor cable fracture of anchorage cable anchoring power will take place unavoidably, even cause the generation of side slope avalanche.Yet; Traditional anchor cable monitoring all is artificial the realization, because the residing geographical environment of a lot of work items is very abominable, even need anchor cable be installed on the very dangerous rock mass and steep cliff; If adopt the personal monitoring, with causing unnecessary personal security accident unavoidably; Also have some anchored force monitoring systems, though adopt intellectual monitoring to act on behalf of the personal monitoring, the certainty of measurement of anchored force is very low.
Along with the development of builing industry and improving constantly of people's safe production awareness; People seem important all the more for the precise monitoring of anchorage force of pre-stressed anchor cable, seek the important topic that a kind of safe and reliable anchorage force of pre-stressed anchor cable monitoring method is called current hydraulic architecture industry.
The utility model content
The purpose of the utility model is to solve the deficiency of prior art; A kind of novel anchorage force of pre-stressed anchor cable real-time monitoring system is provided; Overcome shortcomings such as existing anchorage cable anchoring power monitoring poor stability, certainty of measurement are low; Guaranteed the safety in constructor's work progress, the anchored force situation of real-time remote monitoring anchor cable, unusual circumstance can in time be handled.
The purpose of the utility model realizes through following technical scheme: the anchorage force of pre-stressed anchor cable real-time monitoring system; It comprises prestress anchorage cable, load cell and signal transmission system, and described prestress anchorage cable is made up of guiding cap, anchor supporting plate, anchor plate, extrusion head, isolating frame, constraint circle, grout pipe, anchor clamp and non-bending steel cable, and the anchor plate, extrusion head and the non-bending steel cable extruding that are positioned at the anchoring section front end become single piece; And anchor supporting plate and this single piece are chained together by screw rod; Decomposition pressure type twisted wire bundle, isolating frame, constraint circle and non-bending steel cable are formed tension type twisted wire bundle, and pressure-type twisted wire bundle and tension type twisted wire bundle are organized in together; Guiding cap is fixedly connected with foremost supporting plate; The end of non-bending steel cable is fixedly connected with anchor clamp on the anchor pier, and grout pipe penetrates from the prestress anchorage cable end, through guiding cap place foremost; Be provided with billet between anchor pier and the anchor clamp; Billet is fixedly connected with anchor pier, and load cell is arranged between anchor clamp and the billet, and load cell is connected with a signal transmission system.
The described signal transmission system of the utility model comprises mainboard, signal data transport module and remote server; The output of load cell is connected with mainboard; Mainboard is connected with the input of signal data transport module, and the output of signal data transport module is connected with remote server.
The described signal data transport module of the utility model is the GPRS wireless data transfer module.
The beneficial effect of the utility model is: sensor and Radio Transmission Technology are applied to anchorage cable anchoring power monitoring field, provide a kind of can remote monitoring, security performance is good and certainty of measurement is high anchorage force of pre-stressed anchor cable real-time monitoring system.
