Description
Technical field
The present invention relates to a kind of blipology, especially a kind of drill bursting construction concussion of blasting ultrabroad band signal receives wave detector and method of application.
Background technology
Tunnel Engineering is as a kind of Geological Engineering; Tunnel Design and the preceding engineering geological investigation of construction; Though 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 possibly have bigger 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 restriction constructing tunnel; Because the tunnel front geological condition is not clear, unforeseen geologic hazard often appears often, like gushing water, prominent mud, cave in, rock burst and harmful gas etc.In a single day disaster takes place, and the facility that gently then destroy by rush of water flood the tunnel, and normal construction is compelled to interrupt; Heavy then cause great casualties, produce enormous economic loss, even some underground works can therefore compelledly be suspended or relocate.Radar equipment can carry out constructing tunnel unfavorable geology advanced prediction.Before building hydroelectric project, 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 bigger, and is " a peephole view ", and the geological condition between the hole only depends on supposition, can't confirm.Just since the prospecting data can't entirely accurate the geologic condition of reflection construction front of tunnel heading; Construction has very big blindness; Owing to all kinds of geologic hazards brought out of excavation have not alternative, complicacy, singularity and sudden, thereby usually become the main factor that the restriction tunnel is built.Therefore, constructing tunnel geology advanced prediction is a requisite crucial link in the constructing tunnel process.At present, use the wave detector precision of tunnel advanced prediction and antijamming capability not enough both at home and abroad.
Summary of the invention
The objective of the invention is for overcoming the deficiency of above-mentioned prior art, a kind of emission is provided and receive that signal is good, detection accuracy is high, anti-interference, convenient measurement, drill bursting construction concussion of blasting ultrabroad band signal that measurement coupling precision is high receive wave detector and method of application.
For realizing above-mentioned purpose, the present invention adopts following technical proposals:
A kind of drill bursting construction concussion of blasting ultrabroad band signal receives wave detector; Comprise that cable line, connector, detection core, wave detector draw-in groove, wave detector jacket wall, wave detector branch are to device; Said cable line passes connector, and connector is arranged at the upper end of wave detector jacket wall, and 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 with wave detector and is linked to each other to device, and it be the wave detector jacket wall that wave detector divides to the device outside, between cable line and the connector, to pass through the composite cementitious materials filling between optical cable core and the detection core closely knit.
During use, wave detector is arranged in the tunnel-side buried depth 2m; Near face, when receiving reflection wave signal, wave detector is transferred to demultiplexer with the signal that receives through the optical cable core and carries out Signal Separation as far as possible; And obtain the simulated data of signal, demultiplexer with the simulated data that obtains through joint and cable transmission to A/D converter, generate simulating signal; A/D converter becomes digital signal with the analog signal conversion that generates; Send into single-chip microcomputer then, the function program of single-chip microcomputer through having imported is presented on data terminal with digital signal with the form of curve and carries out image and show.
Composite cementitious materials among the present invention is a current material, repeats no more at this.
The invention has the beneficial effects as follows that the present invention has is simple in structure, detection accuracy is high, anti-interference, convenient measurement, measurement coupling precision advantages of higher.
