Description
Technical field
The present invention relates to tunnel the radar exploration technique field more particularly to a kind of tunnels just to build detection radar pallet apparatus.
Background technique
Ground Penetrating Radar is also known as geological radar or penetrating antenna, is definitely to descend dielectric distribution situation using frequency electromagnetic waves
A kind of lossless geophysical prospecting method, the technology is widely used in the grouting behind shaft or drift lining situation to Shield-bored tunnels at present
Testing inspection, by detection injecting cement paste tunnel is radial and length direction on distributional pattern and injecting cement paste and tunnel duct piece
Between gap (i.e. the thickness and defect of injecting cement paste), to quickly grasp filling situation of the injection slurry between section of jurisdiction and the soil body and apply
Working medium amount provides important evidence for the settlement Control of the shield tunnel in subsequent construction, secondary grouting and compensation and grouting.
Currently, mainly by people station, onboard both hands are lifted during the non-destructive testing of tunnel roof liner concrete quality
Tunnel detection radar carries out the detection work on roof liner surface；There are many deficiencies for this detection mode, such as the safety of personnel
Bad, large labor intensity, testing result inaccuracy and data stability difference etc.；It is certain in spite of Tunnel testing radar is mounted on
The mode manually lifted is substituted on lift mechanism, solves the problems, such as the safety manually lifted and labor intensity, but these
Lift mechanism is without flexibility, and detection radar is actually to resist stubbornly with tunnel roof liner surface, when Uneven road, roof liner surface irregularity
Or detection vehicle is when jolting, if the not height of shutdown adjustment lift mechanism, tunnel detection radar will be detached from roof liner surface or by
Hard pressure, causes that prohibited data detection is true, unstable or detection radar is subject to crushing；In addition, detection vehicle in the detection process can not
It is always maintained at straight-line travelling, detection vehicle " snake " moves or will lead to when turning round detection radar or so offset, can also make to detect thunder
Up to being detached from or resisting stubbornly roof liner surface, equally will cause testing result it is unstable, it is inaccurate or detection radar be subject to crushing it is bad after
Fruit, therefore, in the detection of tunnel roof liner, the mounting device of detection radar is current urgent problem.
Summary of the invention
In view of the above shortcomings of the prior art, the object of the present invention is to provide a kind of tunnels just to build detection radar pallet dress
It sets.
The present invention is achieved by the following technical programs.
A kind of tunnel just block detection radar pallet apparatus, including installing the radar fixed bin of detection radar and being used to support thunder
Up to the flexible supporting device of fixed bin；The radar fixed bin is fixedly installed in the upper end of flexible supporting device；The flexible branch
Support arrangement can guarantee that radar fixed bin is close to detection faces, keep the detection signal stabilization of detection radar reliable.
The flexible supporting device, including hinged supporting means and the piston cylinder branch being fixedly installed on hinged supporting means
Support arrangement；The hinged supporting means make the left and right swing when detecting of radar fixed bin, to adapt to the variation of tunnel face radian；
The piston cylinder support device supports radar fixed bin under the action of the spring, is adjacent to radar fixed bin with tunnel face.
The hinged supporting means, including support plate, mounting plate and the band shaft stool for being mounted on support plate middle position；Institute

One end of support guide rod is fixedly installed with leader fixed；The leader fixed other end is fixedly connected with radar fixed bin；Institute
It states piston cylinder to lift radar fixed bin upwards, support guide rod play the guiding role.
Stress condition is complex in the detection process for the radar fixed bin, the floating junction can piston cylinder by
The piston rod of piston cylinder is protected to be not broken when power is unbalanced.
When detection, whether the radar fixed bin is adjacent to Tunnel testing face, and the influence to testing result is particularly significant, institute
State is adjacent to need Real-time Feedback radar fixed bin and Tunnel testing face；The piston cylinder, including gas pressure sensor；
The gas pressure sensor is mounted on the stomata of piston cylinder lower end；When the gas pressure sensor detects that pressure increases
When, the radar fixed bin and Tunnel testing face paste are tight；When the gas pressure sensor detects that pressure is minimum value, institute
Radar fixed bin 50 is stated to separate with Tunnel testing face；The gas pressure sensor is by pressure signal transmission to the control system of device
System, control system control each device operation to adjust the position of radar fixed bin.
In order to avoid damage detection radar, the radar fixed bin, including box body in detection process；Detection radar is placed on
In box body；Cassette upper end is fixedly installed with multi-directional ball, and multi-directional ball upper surface is higher than detection radar；When detection, the multi-directional ball with
Tunnel face contact avoids detection radar from being worn.
For fixed test radar, the radar fixed bin further includes nut and the bolt with nut cooperation；The box body
Two side walls on respectively processing there are two hole；Four nuts are fixedly mounted on box body, and concentric with the hole on box body；It turns round
Tight bolt can will test radar and hold out against in box body, prevent detection radar from shaking while facilitating installation.
Compared with prior art, the beneficial effects of the present invention are:
1) present invention plays detection radar using double layer support structural support；Lower layer realizes detection radar using articulated manner
