Description
Technical field
The utility model is related to a kind of geophysical data collection servicing unit, and in particular to detects a mine up to support and transmits in ground
Device.
Background technology
To around tunnel and the geological condition of front of tunnel heading is detected, recognizing before tunnel excavation and in work progress
With prediction tunnel tunnel face front and engineering geology, the hydrogeologic structure of surrounding, there is provided accurate fracture belt, water-bearing zone and rock
The geologic parameters such as body works category, can be effectively prevented from engineering geology disease, reduce punishment expense, ensure construction safety and enter
Degree, it is cost-effective.In tunnel detection, the application of GPR widely, GPR（ground penetrating
Radar, abbreviation GPR）It is a kind of generally acknowledged near surface geophysics detection device,, also known as penetrating antenna, geological radar is to use for it
Frequency definitely descends a kind of lossless detection method of dielectric distribution between the radio wave of 10-1000MHz.GPR is general
Using the mode of operation of common offset (common-offset, abbreviation CO).The distance between transmitting antenna and reception antenna are
Fixed, both in surface movement and detect the reflected signal from buried target together.For quantitatively inverting underground medium
Electromagnetic parameter, GPR generally need gather multiple antennas offset data, i.e., transmitting day is altered in steps in same position
The multi-fold data of offset distance and collection from buried target between line and reception antenna.
Therefore GPR can accurately detect front of tunnel heading geological condition, intuitively wait special with high resolution image
Point.However, due in tunnel GPR experiment condition it is severe, tunnel tunnel face is rough and uneven in surface, and surface relief is uneven, causes reality
Test development very difficult.
Being tested by GPR can effectively detect front of tunnel heading geological condition, for unit in charge of construction is provided with reference to money
Material, traditional GPR is general to be moved close to face by the way of hand held antenna, it is necessary to multiple personnel in experiment
Coordinated, because ground and face are uneven, when the face height for needing to measure is higher, it is necessary to use brandreth frame
In tunnel tunnel face front, experimenter is tested at station on brandreth, and environment is very severe in tunnel, ground exploring radar antenna
There is constant weight, the inadequate fast and stable of gatherer process of experimental data can be caused, when testing repeatedly, experimenter can be very tired
Labor, so the experiment method that tradition is not aided in by other equipment is wasted time and energy, while it cannot be guaranteed that data acquisition
Stability.
Therefore, the present inventor passes through further investigation, one kind especially set out can be supported and horizontal for GPR provides stabilization
Thus quick mobile device, this case produces.
Utility model content
The purpose of this utility model is to detect a mine up to support and conveyer with providing, and its is light portable, simple to operate,
Two kinds of detections of polarization mode can be easily realized, solving existing GPR Tunnel prediction experiment wastes time and energy and data
The unstable problem of gatherer process.
To achieve these goals, the technical solution of the utility model is as follows：
Ground is detected a mine up to support and conveyer, is made up of support bar, sliding bearing, drilling nail and lanyard；The support bar
Left and right two ends be connected with a drilling nail respectively, sliding bearing is slided and is nested with support bar, lanyard upper end and sliding bearing company
Connect, lanyard lower end hanging ground exploring radar antenna.
The support bar is expansion link.
After such scheme, when the utility model is used, the drilling nail at support bar two ends is scheduled on tunnel tunnel face front
In the soil body, support bar is suspended on tunnel tunnel face front by the nail that drills, and the sliding bearing for having hung lanyard can be on support bar
Slide, so, it is only necessary to visit radar antenna and carry out transverse shifting, the sliding bearing of lanyard upper end in the ground of hand-held lanyard lower section hanging
The equidirectional movement on support bar, just can Quick Acquisition radar data.
The beneficial effects of the utility model are：Movably hung in front of tunnel heading by the way that ground is visited into radar antenna, it is real
Existing radar data Quick Acquisition, saves testing crew muscle power, improves conventional efficient, and gatherer process is more stable, obtains number
According to more accurately, the utility model also has simple structure, easy-operating feature.
The utility model is described further below in conjunction with drawings and the specific embodiments.
Brief description of the drawings
Fig. 1 is the schematic diagram that the utility model is laid on tunnel tunnel face；
Fig. 2 is three-dimensional shaft side figure of the present utility model.
Label declaration
Support bar 1, sliding bearing 2, drilling nail 3, lanyard 4, ground exploring radar antenna 5, transmission antenna 51, reception antenna 52,
Tunnel tunnel face 6.
Specific embodiment
As illustrated in fig. 1 and 2, the utility model proposes ground detect a mine up to support and conveyer, by support bar 1, sliding axle
Hold 2, drilling nail 3 and lanyard 4 is constituted；The left and right two ends of support bar 1 are connected with a drilling nail 3 respectively, and sliding bearing 2 is slided and is nested with
On support bar 2, the upper end of lanyard 4 is connected with sliding bearing 2, the lower end of lanyard 4 hanging ground exploring radar antenna 5.
When specifically used, referring to Fig. 1, the drilling nail 3 at the two ends of support bar 1 is scheduled in the front soil body of tunnel tunnel face 6,
Support bar 1 is suspended on the front of tunnel tunnel face 6 by the nail 3 that drills, and the sliding bearing 2 for having hung lanyard 4 can be slided on support bar 1
Dynamic, the weight of ground exploring radar antenna 5 is carried by support bar 1, due to the slip friction factor between sliding bearing 2 and support bar 1
Very little, it is only necessary to visit radar antenna 5 and carry out transverse shifting, the sliding bearing 2 of the upper end of lanyard 4 in the ground of the lower section of hand-held lanyard 4 hanging
The equidirectional movement on support bar 1, just can Quick Acquisition radar data.The support bar 1 that this embodiment is used is expansion link, is stretched
Bar can make the adjustable length of support bar 1, to meet different operating modes the need for.
Bottoming out radar system mainly includes computer, radar host computer（Not shown in figure）And radar antenna, computer passes through
Data wire is connected with radar host computer and ground exploring radar antenna 5, and the tunnel tunnel face that real-time reception ground exploring radar antenna 5 is collected
The radar data in front.
The detection of ground exploring radar antenna 5 has two kinds of polarization modes of VV and HH, and wherein VV polarization modes are the Hes of transmitting antenna 51
Reception antenna 52 is placed vertically, and HH polarization modes are transmitting antenna and the equal horizontal positioned of reception antenna, are visited by not same polarization
The experiment of survey mode, can obtain the more radar data information of tunnel tunnel face front, for geologic interpretation provides additional information.
GPR experiment method as shown in Figure 2 is VV polarization detection modes, and ground exploring radar antenna 5 is pulled by changing lanyard 4
Position, by lanyard 4 connect top hook be changed to connection left side hook i.e. be capable of achieving VV polarize detection mode to HH polarization detection side
The change of formula, two kinds of experiments of polarization detection mode, simple to operate can be easily realized by the device
Specific embodiment of the utility model is these are only, not to the restriction of protection domain of the present utility model.It is all according to
The equivalent variations that the mentality of designing of this case is done, each fall within the protection domain of this case.
