Description
Technical field
The utility model relates to a kind of blipology, and especially a kind of drill bursting construction concussion of blasting ultrabroad band signal receives wave detector.
Background technology
Tunnel Engineering is as a kind of Geological Engineering, engineering geological investigation before Tunnel Design and the construction, although to a certain extent the geological state in tunnel is predicted and forecast, because the complicacy of rock mass, the actual conditions behind prospecting data and the tunnel excavation may have larger discrepancy.A large amount of Tunnel Engineering are arranged in China's water conservancy and hydropower, the field of traffic, the Tunnel Engineering geologic hazard is the key factor of tunnel construction construction, because the tunnel front geological condition is not clear, unforeseen geologic hazard often appears often, such as gushing water, prominent mud, cave in, rock burst and harmful gas etc.In a single day disaster occurs, and the facility that gently then destroy by rush of water flood the tunnel, and normal construction is forced to interrupt; Heavy then cause great casualties, produce huge economic loss, even therefore some underground works can be forced to suspend or relocate.Radar equipment can carry out constructing tunnel unfavorable geology advanced prediction.Before hydro-engineering, at first to carry out engineering geological investigation.The common means that adopt of engineering geological investigation are probings, and its advantage is directly simple, and shortcoming is higher to the space requirement in place, and expense is larger, and is " a peephole view ", and the geological condition between the hole only depends on supposition, can't determine.Just since the prospecting data can't entirely accurate the geologic condition of reflection construction front of tunnel heading, construction is with very large blindness, all kinds of geologic hazards of bringing out owing to excavation have Non-selectivity, complicacy, singularity and sudden, thereby usually become the main factor that tunnel construction is built.Therefore, the tunnel working geology advanced prediction is a requisite very important link in the constructing tunnel process.At present, use the wave detector precision of Tunnel prediction and antijamming capability not enough both at home and abroad.
The utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, providing the drill bursting construction concussion of blasting ultrabroad band signal that a kind of emission is good with the reception signal, detection accuracy is high, anti-interference, measurement is convenient, the measuring coupling precision is high to receive wave detector.
For achieving the above object, the utility model adopts following technical proposals:
A kind of drill bursting construction concussion of blasting ultrabroad band signal receives wave detector, comprise cable line, connector, the detection core, the wave detector draw-in groove, the wave detector jacket wall, wave detector divides to device, described cable line passes connector, connector is arranged at the upper end of wave detector jacket wall, the optical cable core of cable line front end links to each other with the detection core, detection core lower end is stuck in the wave detector draw-in groove, the detection core outside is divided to device with wave detector and is linked to each other, it is the wave detector jacket wall that wave detector divides to the device outside, between cable line and the connector, fill closely knit by composite cementitious materials between optical cable core and the detection core.
During use, wave detector is arranged in the tunnel-side, buried depth 2m, as far as possible near face, when receiving reflection wave signal, wave detector is transferred to demultiplexer with the signal that receives by the optical cable core and carries out the signal separation, and obtain the simulated data of signal, demultiplexer arrives A/D converter with the simulated data that obtains by joint and cable transmission, generate simulating signal, A/D converter becomes digital signal with the analog signal conversion that generates, and then sends into single-chip microcomputer, the function program of single-chip microcomputer by having inputted is presented on data terminal with digital signal with the form of curve and carries out image and show.
Composite cementitious materials in the utility model is current material, does not repeat them here.
The beneficial effects of the utility model are, the utlity model has simple in structure, detection accuracy is high, anti-interference, measure convenient, measuring coupling precision advantages of higher.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, drill bursting construction borehole blasting vibrations ultrabroad band signal receives wave detector and method, comprise that cable line 1, connector 2, composite cementitious materials 3, optical cable core 4, detection core 5, wave detector draw-in groove 6, wave detector jacket wall 7, wave detector divide to device 8, detection core 5 is arranged at wave detector draw-in groove interior 6, top is connected with optical cable core 4, the both sides tie geophone divides to device 7, fills closely knit with composite cementitious materials 3 between cable line 1 and the connector 2, between optical cable core 4 and the detection core 5.
During use, wave detector is arranged in the sidewall, buried depth 2m, as far as possible near face, when receiving reflection wave signal, divide to device 7 biographies to detection core 5 by wave detector, then be transferred to switch by optical cable core 4 and carry out the signal conversion, be transferred to the processor that is positioned at the quick-fried backstage of brill by switch again and carry out the signal processing, the final biography to data terminal carried out the image demonstration.
Although above-mentionedly by reference to the accompanying drawings embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
