Description
Technical Field
The utility model belongs to the field of anchor rod stress monitoring, and relates to an anchoring failure early warning device which can realize anchor rod bearing monitoring and anchoring failure early warning in anchoring projects of road slopes, water conservancy and hydropower, bridges, tunnels and mine roadways.
Background
With the rapid development of the infrastructure of China, a large number of road slopes, bridge tunnels and mine roadways appear, and due to the fact that the geological conditions of many projects are complex and the factors influencing deformation and damage of anchored objects are numerous, the support problem brought by the method is quite prominent. The anchor rod is used as the most basic component of the existing anchoring support, and anchors the surrounding rock which is easy to deform on the surface layer and the deep stable surrounding rock together, thereby playing the role of anchoring support while fully playing the self-capability of the surrounding rock. Practice proves that the anchoring support taking the anchor rod as the core component is the economic and efficient support technology at present.
As the anchor rod in the anchoring and supporting engineering is subjected to the influences of tensioning and pre-tightening, coordinated deformation and dynamic load deflection in the service period, the load of the anchor rod is in dynamic change. The anchor rod in the anchoring and supporting engineering is influenced by factors such as deformation and damage of the anchored surrounding rock, dislocation of rock stratum, anchoring slip and the like, and the anchor rod often has anchoring failure phenomena such as slippage, debonding, bending torsion, pulling shear, breaking and the like. Because the anchor rod belongs to the recessive support, and the monitoring is difficult to develop in the anchoring deep part, the sudden accident without obvious symptoms often appears. Therefore, how to master the key parameters of the anchor rod in the anchoring support is important to develop monitoring and early warning so as to effectively avoid accidents.
The anchor rod has different tail axial forces in different anchoring periods and before anchoring failure occurs. When the strength of the anchor rod is insufficient and the stress is overlarge, the anchor rod generates large yielding deformation and even breaks. When the strength of the anchor rod is enough, but the surrounding rock adhesion force of the anchoring section is insufficient or the shear strength of the anchor rod-anchoring agent interface is low, the anchor rod slips and fails, the anchor rod can hardly provide the anchoring force at the moment, and the axial force of the anchor rod is zero. Therefore, the axial force of the tail part of the anchor rod is dynamically mastered, and early warning research and judgment can be carried out on anchor failure of the anchor rod.
At present, in the process of monitoring and early warning the stress of an anchor rod, the traditional anchor rod bearing monitoring device can only play a single function, and has a relatively complex structure and is complex to assemble and disassemble; moreover, the stress of the anchor rod cannot be stored and collected, and the first warning time cannot be missed due to the absence of an audible and visual alarm device; meanwhile, dynamic monitoring of roadway anchoring support cannot be obtained and realized when slippage fails; even, professional technicians are needed in the detection process, and wireless standard exceeding mode collection of monitoring data cannot be performed, so that the universality and the data collection efficiency are low. Therefore, it is important to provide an anchor rod anchoring failure early warning device which has a relatively simple structure, is easy and convenient to assemble and disassemble, can perform timely audible and visual alarm, can perform real-time monitoring and can remotely and wirelessly transmit data.
