There is a joint between two adjacent pipe galleries. The waterproofing and anti-seepage of the joint are the top priorities in the construction and management of the pipe gallery. During use, the structural deformation of the two adjacent pipe galleries at the joint needs to be closely monitored.

Compared with the related art, the present application drives the measuring member to move by the sliding member, and the detection member moves synchronously with the measuring member, so as to measure other positions of the splicing seam of the pipe gallery, which is convenient for measuring multiple groups of data, which is conducive to improving the problem of inaccurate measurement results.

[0009] Optionally, three measuring pieces are provided, and the three measuring pieces are all located on the fixing plate, and the distribution direction of the three measuring pieces is consistent with the axial direction of the pipe gallery;

[0010] There are three detection members, and one detection member corresponds to one measuring member.

[0011] By adopting the above technical solution, it is necessary to connect the measuring piece with the sliding piece, take out the measuring piece, and connect the measuring piece with the sliding piece in sequence. Then, take out the detection piece, the detection piece corresponds to the measuring piece, and connect the detection piece with the measuring piece. When it is necessary to measure the deformation of the splicing seam of the corridor, three measuring pieces and three detection pieces are started at the same time, and multiple positions of the splicing seam of the corridor can be measured simultaneously. The sliding piece can drive the measuring piece to move. By setting three measuring pieces and three detection pieces, it is helpful to measure multiple positions of the splicing seam of the corridor at the same time.

[0012] Optionally, a slide groove is provided on the side of the fixed plate away from the pipe gallery, and the setting direction of the slide groove is consistent with the axial direction of the pipe gallery.

The sprocket is rotatably connected to the fixed plate, and the chain is wound between the two sprockets, and the measuring member is connected to the chain.

[0013] By adopting the above technical solution, when it is necessary to drive the measuring piece to move, the personnel starts the sprocket to rotate. During the rotation of the sprocket, the sprocket drives the chain to move. At this time, the measuring piece moves with the chain. By setting the sprocket and the chain, it is convenient to drive the measuring piece to move and convenient for personnel to operate.

[0014] Optionally, a plurality of mounting seats are evenly fixed on the chain, and the plurality of mounting seats are spaced apart along the conveying direction of the chain;

[0015] The measuring member includes two fixed supports, two connecting rods, two horizontal guide rails, a vertical guide rail and a sliding rod, the two fixed supports are close to one of the chains, one fixed support is connected to one mounting seat, a mounting seat is left between the two fixed supports, one connecting rod corresponds to one fixed support, the connecting rod is horizontally arranged, the setting direction of the connecting rod is perpendicular to the axial direction of the pipe gallery, one end of the connecting rod is fixed to the fixed support, and the other end is close to another fixed plate, one horizontal guide rail is fixed to one connecting rod, The horizontal guide rail is close to the end of the connecting rod away from the fixed support, and a first sliding hole is formed on the horizontal guide rail, and the length direction of the first sliding hole is parallel to the axial direction of the pipe gallery. The vertical guide rail is close to the fixed plate that is not connected to the fixed support, and the vertical guide rail is connected to the mounting seat. The vertical guide rail and the fixed support are correspondingly arranged, and a second sliding hole is formed on the vertical guide rail, and the length direction of the second sliding hole is perpendicular to the axial direction of the pipe gallery. The sliding rod can be slidably inserted in the first sliding hole and the second sliding hole, and the detection member is connected to the sliding rod.

[0016] By adopting the above technical scheme, when the pipe gallery connected to the vertical guide rail moves, that is, when the pipe gallery joint changes, the fixed plate moves synchronously with the pipe gallery, and the fixed plate can drive the vertical guide rail to move, and the sliding rod slides along the length direction of the second sliding hole.

Neither the horizontal displacement sensor nor the vertical displacement sensor is subjected to the shear force generated by the deformation of the tunnel splicing seam structure. Therefore, the service life of the horizontal displacement sensor and the vertical displacement sensor is significantly improved. By setting the horizontal displacement sensor and the vertical displacement sensor, on the one hand, it is convenient to detect the displacement of the sliding rod; on the other hand, it is beneficial to improve the service life of the measuring device.

[0019] Optionally, a diameter of the sliding rod is slightly smaller than a width of the first sliding hole and a width of the second sliding hole.

Subsequently, the horizontal displacement sensor and the vertical displacement sensor transmit the detected signal to the data processor through the controller. The data processing unit comprehensively calculates the total deformation of the corridor splicing seam according to the detection signals of the horizontal displacement sensor and the vertical displacement sensor. By setting up a data processor, it is convenient to comprehensively calculate the total deformation, which effectively improves the measurement accuracy.

[0024] By adopting the above technical solution, when the measuring piece needs to move, the driving piece is started, and the driving piece drives the transmission rod to rotate. During the rotation of the transmission rod, the transmission rod drives the sprocket to rotate, the sprocket can rotate the chain, and the sprocket can drive another sprocket to rotate through the chain, thereby enabling the measuring piece to move. By setting the cooperation between the transmission rod and the driving piece, only one driving piece needs to be started to make the sprockets on the two fixed plates rotate at the same time, which is convenient for personnel to operate.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:
