Description
Technical field
The utility model relates to the geophysical probing technique using radar pulse electromagnetic wave detection stratigraphic structure, particularly relates to transmitting, ground receiver radar detection apparatus in hole.
Background technology
Use radar detection stratigraphic structure, launch frequency electromagnetic waves by emitting antenna to underground, received by receiving antenna and be reflected back the electromagnetic wave on ground, infer the locus of underground medium, structure, form and depth of burial according to features such as the electromagnetic waveform received, oscillator intensity and the changes of time.Because ground ground penetrating radar is at earth's surface emitting electromagnetic wave, very large by neighbouring earth's surface object, high-altitude stringing and the noise jamming from each side, affect radar imagery effect.In addition ground launch and reception electromagnetic wave, experience is launched and reflection secondary communication process, and electromagnetic wave energy is subject to two-way attenuation, and affects by stratum media conductivity, causes detection depth of stratum to be limited in scope.In such cases, if emitting electromagnetic wave in the borehole, at ground receiver electromagnetic wave, in this process, radar wave only experiences a direct propagation, compared with ground launch with to receive experience secondary Propagation of Energy stronger.Transmitter is arranged in noiselessness boring simultaneously, disturbs little, detection coverage can be made larger, radar imagery better effects if.
Utility model content
The technical problems to be solved in the utility model is, provide a kind of in the boring of noiselessness interference emitting electromagnetic wave, not by each side's noise jamming, make detection coverage large, launch in the hole that radar imagery is effective, ground receiver radar detection apparatus.
The technical scheme adopted is:
In hole, transmitting, ground receiver radar detection apparatus, comprise boring, protection casing, tripod, emitting antenna, guiding hammer, receiving antenna, counter, data processing host, computing machine and data line.Described boring is the boring of boring a set depth at detected stratum engineering driller, in protection casing implant bore, in case collapse hole, the tripod fixed on the ground is provided with above the protection casing being positioned at drilling orifice place, emitting antenna is suspended on tripod top counter disk, and by counter controls lifting distance and speed on it, guiding hammer is cared in emitting antenna lower end, to control to be elevated direction, described emitting antenna and the guiding cared for are hammered into shape and are jointly contained in protection casing, receiving antenna is arranged around the ground near drilling orifice protection casing, receiving antenna one end is connected with emitting antenna with Transmission Fibers cable, the other end is connected with data processing host with Transmission Fibers cable, data processing host is connected with computing machine with data line.
The utility model avoids collapse hole to cause antenna to be buried at boring interplantation protection casing, and emitting antenna unobstructed movement under the guiding of guiding hammer, avoids antenna by card.Extremely be suitable for radar antenna repeatedly to detect in hole, rational in infrastructure, not by each side's noise jamming, detection coverage is large, and radar imagery is effective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Transmitting, ground receiver radar detection apparatus in hole, comprise boring 10, protection casing 6, tripod 5, emitting antenna 9, guiding hammer 11, receiving antenna 7, counter 4, data processing host 2, computing machine 1 and data line 12.Described boring 10 is the boring of boring a set depth at detected stratum engineering driller, in protection casing 6 implant bore 10, in case collapse hole, the tripod 5 fixed on the ground is provided with above the protection casing 6 being positioned at boring 10 aperture place, emitting antenna 9 is suspended on tripod 5 top counter 4 disk, and control lifting distance and speed by counter on it 4, guiding hammer 11 is cared in emitting antenna 9 lower end, to control to be elevated direction, described emitting antenna 9 is hammered 11 into shape with the guiding cared for and is jointly contained in protection casing 6, receiving antenna 7 is arranged around the ground near boring 10 aperture protection casing 6, receiving antenna 7 one end is connected with emitting antenna in hole 9 with Transmission Fibers cable 3, the other end is connected with data processing host 2 with Transmission Fibers cable 3, data processing host 2 is connected with computing machine 1 with data line 12.
Principle of work
During the detection of this device, the position motionless emitting electromagnetic wave of emitting antenna 9 in protection casing 6, receiving antenna 7 is at edge, ground mobile reception electromagnetic wave in region centered by aperture protection casing 6.Then, emitting antenna 9 moves down a fixed range, and receiving antenna 7 receives electromagnetic wave at ground the same area.This step repeats, until emitting antenna 9 moves at the bottom of hole.To scanning each time, electromagnetic wave is by Transmission Fibers cable 3 signal transmission, and digital processing main frame 2 and computing machine 1 record and process direct wave 8 signal, forms search coverage radar image.Analyze by the attenuation change of direct wave 8 amplitude, speed and explain stratigraphic structure.
