Abstract
The utility model discloses a displacement is met an emergency stock and is synthesized early warning system mainly includes: the stock body of rod, displacement strainometer, signal transmission line way, wall anchor lock end, signal receiving and processing ware, sensing chip, signal output pipe and siren. Offer the shallow slot in the stock body of rod, the even compartment of displacement strainometer arranges in the shallow slot, and stock deformation parameter spreads out of through the signal transmission line way in proper order, and the signal arrives built -in sensing chip's signal receiving and processing ware through wall anchor lock end, and the signal receiving and processing ware carries out data analysis and signal processing to displacement parametric signal, and when the displacement deflection surpassed the maximum permissible specified deformation value that stock self bore, alarm instruction passed through signal output and manages and transmit to the siren, sends signal transmission line 0. The utility model discloses broken traditional stock strut alone with monitoring and early warning's separation module formula, realized anchor bolt support and the perfect unified of monitoring and early warning and organic reconstruction, to maintaining that the tunnel is stable, ensuring safety production has the important function.
Description
Technical field
The utility model relates to deformation of the surrounding rock in tunnel monitoring and supporting effect evaluation analysis field, is specially a kind of displacement strain anchor pole Integrated Early Warning System.
Background technology
The support pattern of roadway surrounding rock is divided into active support and passive protecting two kinds usually, passive protecting generally adopts the metal shaped steel such as U-shaped steel, i iron, trapezoidal steel canopy to help country rock to carry out passive carrying supporting to back and two, because Support Resistance is on the low side, support force skewness causes support pressure-bearing unbalance loading easily to cause deformation of timbering and damage; Active support is then based on bolt support, bolt support can effectively limit anchorage zone country rock dynamic expansion, interlayer drift, crack expansion and bedding plane slip, give full play to the mechanics load-carrying properties of roadway surrounding rock, be convenient to form secondary carrying key stratum with effect country rock space, expand carrying scope and the radius of action of rock mass, improve the structural integrity of supporting section, stressed continuity and resistance to overturning, reduce the crack initiation deformation of country rock and be caving destruction.Due to the outstanding advantage of bolt support, it is made to have broad application prospects in colliery tunnel support field.But in bolt support process, how its Bracing Process effectively to be followed the trail of and supporting performance evaluation becomes new technical barrier, existing way adopts resistance-strain monitor and displacement strain-gage instrumentation to carry out strain monitoring to operation anchor pole separately usually, by anchor pole one by one wiring and carry out stress or displacement strain testing investigation, find out hidden danger one by one and judge whether that supporting was lost efficacy, this way construction sequence is loaded down with trivial details, and test step is complicated, and wastes a large amount of manpower and materials.Along with coal mining mechanization, automation, intelligent level improve constantly and fast-developing, improve monitoring means and the early warning technology of roadway surrounding rock bolt support, form bolt support, action system that deformation monitoring, forecasting and warning several functions work in coordination with fusion becomes further urgent.
Summary of the invention
The utility model overcomes the shortcoming that the independent supporting of existing anchor pole and monitoring and warning are separated from each other, and provides the novel displacement strain anchor pole Integrated Early Warning System of a kind of Reasonable Support, efficient early warning, the support monitoring coordinating and unifying.
For achieving the above object, the technical solution adopted in the utility model is as follows: described displacement strain anchor pole Integrated Early Warning System, is locked termination, signal receiving processor, induction chip, signal efferent duct and alarm buzzer formed by anchor rod body, displacement strain meter, signal transmission line, wall anchor.Shallow slot is offered in described anchor rod body, described displacement strain meter uniform intervals formula is arranged in shallow slot, bolt deformation parameter is spread out of successively by signal transmission line, signal arrives the signal receiving processor of built-in sensitive chip through wall anchor lock termination, signal receiving processor carries out data analysis and signal transacting to displacement parameter signal, when displacement deformation amount exceedes the specified deformation values of maximum permission that anchor pole self bears, alarm command is passed to alarm buzzer by signal efferent duct, send alarm signal, field personnel's bolt support is reminded to lose efficacy, need to carry out consolidation process to supporting section in time.
According to described system, described displacement strain meter connects through by signal transmission line, and in spread in anchor rod body.
According to described system, anchor rod body is closely fixed among country rock by described wall anchor lock termination, and described induction chip is placed in signal receiving processor inside, undertakes the data processing maincenter of Displacement-deformation signal.
According to described system, described alarm buzzer is displacement strain sensor, only has when displacement deformation amount exceedes the specified deformation values of maximum permission that anchor pole self bears, just can send alarm signal.
Compared with prior art, the beneficial effects of the utility model are: this system has broken the clastotype of the independent supporting of conventional anchor and monitoring and warning, achieve the perfect unity of bolt support and monitoring and warning and organic restructuring, prior-warning device is added in anchor pole, the effect of anchor pole active support can not only be played to greatest extent, and can to deform unstability so that lose anchorage effect and monitor timely and effectively by surrouding rock stress to anchor pole, to safeguarding stability of the roadway, guaranteeing safe production has important function.
