Description
Technical field
The utility model relates to shield tunnel excavation and grouting behind shaft or drift lining detecting devices.
Background technology
The detection of shield tunnel grouting behind shaft or drift lining is at the traffic and the municipal tunnel that adopt shield construction, by test the grouting behind shaft or drift lining body distribution situation of the subway tunnel in construction is surveyed.Because the lining wall grouting behind shaft or drift lining of shield tunnel can not be tested by the method for boring, the detection technique method that requires constructing tunnel to accurately and fast, undamaged direction develops.Comprehensive various lossless detection method, geological radar method of testing have non-destructive, speed of detection fast, survey degree of accuracy height, the long advantage of detection range, but its testing apparatus can not be applicable to the detection of shield tunnel grouting behind shaft or drift lining, must be improved design.
Summary of the invention
The proving installation that provides a kind of shield tunnel grouting behind shaft or drift lining geologic radar detection to use is provided the purpose of this utility model, and this device can be fit to the geology radar application and carry out the grouting behind shaft or drift lining geologic radar detection in shield tunnel.
The technical solution of the utility model is: at first will reequip antenna, make the detection of antenna adaptation in the tunnel.In shield tunnel, carry out to survey detection longitudinally in the grouting behind shaft or drift lining body distribution detection study with hoop.The survey line position that has is than higher, and maintenance is stable in detection process.Adopt the fixed antenna spacing, antenna is fixed on framework inside, antenna branch separation is fixed, the effect of protection antenna is arranged simultaneously.For this reason, the specially design and make antenna holder must be taken into account several aspects such as safe, firm and quality to newly-designed antenna holder.Antenna holder, form by deckle board, antenna protection plate, antenna plate cushion block and castor, timbering material is selected plastic-steel or timber, antenna plate is fixed in the above keeps the setpoint distance of center of antenna distance, four castors are set on it, the resistance of when antenna moves, reducing friction, three universal hinge supports are set above antenna holder,, or connect hoist cable so that connect pole; Backing plate has two kinds, and a kind of is the cushion block of supporting transmitter or receiver, and another kind is a cushion block of supporting antenna plate.Is connected with antenna plate because transmitter (receptions) machine is the latch by steel, very instability of a space is arranged between transmitter or receiver and the antenna plate, two wood block fillers of need installation, the length of cushion block is the width sum that the width of antenna plate adds fender.Earlier antenna plate and emission (reception) machine cushion block are connected and fixed, and then are connected with the antenna plate cushion block, need be placed on antenna protection plate inboard, (seeing shown in Figure 2) makes antenna holder more firm.In detection, searching surface is curved, antenna is difficult for and closely knit contact the in surface, section of jurisdiction when carrying out longitudinal probing on the curved surfaces in tunnel, influence detection accuracy (seeing shown in Fig. 3 A), hoop but can add an antenna plate cushion block when surveying between antenna plate and antenna holder, make and form certain angle between the antenna, (seeing shown in Fig. 3 B), for this designs two groups of different antenna plate cushion blocks to different side lines, in longitudinal probing, use the rectangular parallelepiped cushion block, and in hoop is surveyed, using another group prismatoid cushion block, two kinds of cushion blocks all are to make the antenna surface, section of jurisdiction of as far as possible closely fitting, and reduce the influence to detection accuracy.The cushion block material is selected polyfoam, so that reduce weight.The cushion block that hoop is surveyed usefulness is prismatoid.
The utility model has the advantages that: to the geology radar application after the detecting devices of shield tunnel grouting behind shaft or drift lining is changed a social system, in tunnel detection, still be that hoop is surveyed no matter to longitudinal probing, the requirement that can both reach non-destructive, speed of detection is fast, detection accuracy is high and detection range is long.

Embodiment
See also shown in the accompanying drawing 1,2,4; the utility model comprises antenna plate, antenna holder and emission (reception) machine cushion block; wherein; antenna holder is by two deckle boards 1; two blocks of antenna protection plates 3 and four antenna plate cushion blocks 2 combine; and four castors 4 are housed in deckle board bottom, so that reduce friction resistance when mobile.One antenna plate 6 is connected with antenna plate cushion block emission (reception) machine cushion block 7, antenna plate 6 and emission (reception) machine cushion block 7 all have connecting hole, be connected with the copper latch of transmitter 5, two antenna plate cushion blocks 2 in addition last and antenna holder are connected antenna protection plate 3 inboards again; Three universal strand bearings, three angles that are installed in antenna holder are located.And two batteries respectively are installed at transmitter 5 and receiver 8 both sides.The length of above-mentioned emission (reception) machine cushion block 7 is that the antenna plate width adds antenna protection plate width sum again; be the length of emission (reception) machine cushion block 7; because the tunnel longitudinal probing is different with the hoop detection, so difformity need be set, the emission of different length and different-thickness (reception) machine cushion block.
