The waterproof board is an impermeable material prepared by using a high molecular polymer as a basic raw material, and can prevent liquid leakage and gas volatilization. The method is widely applied to buildings, traffic, subways, tunnels and engineering construction. In order to improve the waterproof performance of the tunnel in the tunnel construction process, a waterproof plate is usually required to be laid on the surface of the inner wall of the tunnel.

Since the tunnel has a certain length, the flashing laying machine usually needs to be moved along the length of the tunnel during the laying process in order to lay the tunnel in its entirety. The existing paving machine usually adopts pulleys to move, because the paving machine has large mass, a plurality of groups of pulleys are usually adopted to support the paving machine, and when the paving machine works, the running state between the plurality of groups of pulleys and the ground is usually required to be limited in order to ensure the stable operation of the paving process, and the existing paving machine is not convenient to simultaneously limit the running state between the plurality of groups of pulleys and the ground. In addition, because the waterproof board is the film body of reel form, usually with the waterproof board wire-wrap at putting the membrane roller surface, through putting the rotation of membrane roller so that the interior arc surface of tunnel can lay, but because the radius of different tunnels is different, it is difficult to closely follow the interior arc surface of tunnel to put the membrane roller, reduces the effect that the waterproof membrane was laid to a certain extent.

In some specific embodiments, a sliding plate 1634 is sleeved on an outer wall of the extending plate 1632, the sliding plate 1634 is slidably installed inside the supporting plate 161, a second elastic member 1635 is disposed between the sliding plate 1634 and an inner side wall of the supporting plate 161, the second elastic member 1635 has the same structure as the first elastic member 220, during the outward extension of the extending plate 1632, the second elastic member 1635 is compressed, after the cam 1631 returns to the initial position, the horizontal length of the cam 1631 is reduced, and the extended extending plate 1632 is contracted by a reaction force of the compression of the second elastic member 1635.

The working principle of the waterproof board laying machine for tunnel construction is as follows: the frame 110 moves into the tunnel, because the inside of the moving seat 120 is rotatably installed with a plurality of rotating columns 121, the plurality of rotating columns 121 are in transmission connection through the transmission member 130, the output shaft of the first motor 140 is in transmission connection with one rotating column 121, so that the rotation of the output shaft of the first motor 140 drives one rotating column 121 to rotate, and further drives a plurality of rotating columns 121 to rotate synchronously, because the top of a plurality of pulleys 150 is provided with a fixed rod 151, the fixed rod 151 is fixedly installed at the bottom of the rotating column 121, so that the plurality of rotating columns 121 rotate to drive a plurality of fixed rods 151 to rotate, so that the fixed rods 151 rotate 90 degrees, and further the pulleys 150 are accommodated inside the moving seat 120, so that the pulleys 150 do not contact with the ground, thereby the moving seats 120 at both sides are in contact with the ground, so that the frame 110 is not easy to move, because the waterproof board is in the shape of a thin film body, the waterproof board is wound on the surface of the film-releasing roller 231, and the first elastic member 220 is compressed, make the membrane roller 231 of putting of roll body support 230 one end temporarily separate with the tunnel inner wall, later send out first elastic component 220, reaction force after first elastic component 220 compression, make the waterproof board of putting the membrane roller 231 surface paste the inner wall surface in tight tunnel, second motor 210 output shaft rotates and drives bull stick 211, and then drive the first elastic component 220 rotation of the front end of bull stick 211, make and put the synchronous rotation of membrane roller 231, and then so that the waterproof board of putting the membrane roller 231 surface lays the inner wall in the tunnel.

It should be noted that the specific model specifications of the first motor 140, the electric cylinder 160, the second motor 210, and the third motor 1621 need to be determined by type selection according to the actual specification of the device, and the specific type selection calculation method adopts the prior art in the art, and therefore details are not described again.

The power supply of the first motor 140, the electric cylinder 160, the second motor 210, the third motor 1621 and the principle thereof will be apparent to those skilled in the art and will not be described in detail herein.
