Description
Technical field
The utility model is related to duct pieces of shield tunnel detection device technical fields, and in particular, to a kind of shield tunnel use
The adaptive rackwork of ground exploring radar antenna.
Background technology
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, at present the technology be widely used in the grouting behind shaft or drift lining situation to Shield-bored tunnels
Testing inspection, by detect 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.
Ground Penetrating Radar detection device includes mainly radar host computer, communication Hawser and shielded antenna, and wherein shielded antenna is outer
Shape is similar to cuboid and is provided with the high frequency antenna (400MHz-1GHz) that can emit electromagnetic wave inside it, and high frequency day
Centre frequency possessed by line is higher, and the size of entire shielded antenna is also smaller；Meanwhile it need to be arranged including vault on section of jurisdiction surface
5-9 items detection circuit (referred to as " survey line ") inside, the length direction of these surveys line is identical as the length direction in tunnel.
In the prior art, radar data is typically completed by way of manually lifting on the railcar train of traveling
Collecting work, operating personnel need to the hands hold shielded antenna high so that shielded antenna and the tunnel near measurement circuit
It is close on the surface of section of jurisdiction.Since shield tunnel is different from conventional mountain tunnel, operating personnel can only stand at the top of train, and
Space at the top of train is smaller, and operating personnel are when being detected the survey line other than keystone, it is necessary to which shielded antenna is long
Temporally tilt and lift, force is difficult, not only needs the multiple midway rotation of operating personnel or rest, time-consuming and laborious, can also when not
When there is the case where being detached between antenna and section of jurisdiction surface so that data acquisition is forced interrupt or suspend, seriously affect section of jurisdiction
The quality of data of grouting behind shaft or drift lining quality testing causes the noise of data relatively low, and the repetition measurement rate of survey line is higher, greatlys restrict
The accuracy of detection and operating efficiency of shield tunnel grouting behind shaft or drift lining situation.
If being laid with the detection platform that horizontal cross lengthens at the top of train, although personnel easy to operation are laborsaving when lifting,
But it influences whether the normal construction of Other Engineering personnel, and is unable to ensure operating personnel and communicates the safety of Hawser.Even if installing additional
Detection platform, since the size of shield tunnel is different, railcar train length of different size, detection platform is different and
The problems such as radian difference of different location tunnel duct piece, still remains, so operating personnel are still unavoidable from when lifting antenna
The break-off of shielded antenna and section of jurisdiction surface, causes test data to rise and fall, and large error occurs in testing result, after influencing
The construction quality of phase secondary grouting.
Another influences the reason of shielded antenna and arc section of jurisdiction contact interface can not fit closely, and is track train
Gait of march is too fast or speed is uneven, since host service function personnel can in time assist according to the quality of on-site data gathering quality
The gait of march of the close degree and railcar train of antenna is adjusted, and the cooperation between driver and operating personnel cannot protect
Barrier, not only the quality of detection data can not ensure, more likely cause the collision of personnel and instrument and equipment and fall.
