Detailed implementation mode

[0025] The following combines Figures 1 to 3 to describe the present invention in detail.

[0026] A construction support device and construction method for a short - distance water diversion tunnel, including a tunnel 1, a bench 2 is connected to the middle of the tunnel 1, a slide rail 201 is arranged on the top of the bench 2, a laying device 3 is connected to the top of the slide rail 201, a connecting frame 301 is arranged in the middle of the laying device 3, a laying roller 3011 is connected to the top of the connecting frame 301, a driving roller 304 is connected to the bottom of the laying device 3, a laying frame 302 is connected to one side of the top of the laying device 3, a deflecting frame 303 is connected to one side of the laying frame 302, a rotating disk 3031 is connected to one end of the deflecting frame 303, an abutting assembly is connected to one side of the laying frame 302, the abutting assembly is in transmission connection with the rotating disk 3031, the slide rail 201 further includes a displacement slot 202, the displacement slot 202 is arranged on both sides of the middle of the slide rail 201, the bottom of the laying device 3 cooperates with the slide rail 201, and the laying device 3 cooperates with the displacement slot 202 through the bottom driving roller 304, and the driving roller 304 is in transmission connection with a motor.

[0027] First, push the bench 2 into the tunnel 1, then turn on the motor on the laying device 3 to drive the driving roller 304 to rotate. Through the rotation of the driving roller 304, it meshes and rotates with the rack of the displacement slot 202 in the slide rail 201, thereby driving the laying device 3 to move along the slide rail 201. When the laying device 3 moves along the slide rail 201, the waterproof cloth will be covered on the concrete layer on the inner wall of the tunnel 1 through the laying roller 3011 on the middle connecting frame 301, and there is no need for construction workers to cover and connect the waterproof cloth at the high place of the tunnel 1.

[0028] Further, tooth marks meshing with the bottom rack of the displacement slot 202 are arranged on the side wall of the driving roller 304. The laying frame 302 further includes a hinge block 2021, the hinge block 2021 is arranged on one side of the laying frame 302, one end of the laying frame 302 is hinged to one side of the top of the laying device 3, and the hinged part of the laying frame 302 is connected by a torsion spring. A torsion spring is arranged at the hinge of the deflecting frame 303 and the hinge block 2021.

[0029] When the waterproof cloth is laid out by the laying roller 3011 at the same time, the laying frame 302 on one side of the top of the laying device 3 will fit onto the surface where the waterproof cloth has been laid. Then, through the articulated torsion spring connection of the laying frame 302, pressure will be exerted on the surface of the laid waterproof cloth, and then it will move while exerting pressure on the surface of the waterproof cloth following the movement of the laying device 3, so as to make the adhesion of the waterproof cloth more stable.

[0030] Furthermore, the rotating disk 3031 further includes a transmission rod 3032. The transmission rod 3032 penetrates through both sides of the top of the laying device 3, and the protruding part of the transmission rod 3032 is in the middle of the laying device 3. The abutting assembly includes a flattening block 305, a connecting block 3051, a conveyor belt 3052, and an abutting block 3053. The flattening block 305 is arranged on one side of the deflecting frame 303. The connecting block 3051 is arranged on one side of the flattening block 305. The conveyor belt 3052 is connected to the side wall of the flattening block 305. The abutting block 3053 is arranged on the surface of the conveyor belt 3052. The flattening block 305 is arranged on the opposite side of the deflecting frame 303. The flattening block 305 is connected to the deflecting frame 303 through a connecting block 3051 on one side. Both ends of the flattening block 305 are connected with rollers, and the rollers are in contact with the conveyor belt 3052. The abutting blocks 3053 are a plurality of triangular bumps arranged in an arc shape and connected to the surface of the conveyor belt 3052. One side of the conveyor belt 3052 is in contact with the protruding part of the transmission rod 3032, and the teeth on the protruding part of the transmission rod 3032 mesh with the teeth on one side surface of the conveyor belt 3052.

[0031] When the laying frame 302 deflects and abuts against the waterproof cloth at the same time, the deflecting frame 303 connected by the hinge block 2021 on one side will also deflect to one side through the torsion spring and fit onto the waterproof cloth. When the deflecting frame 303 approaches and fits onto the waterproof cloth, it will abut against the waterproof cloth through the rotating disks 3031 on both sides, and then rotate and roll on the waterproof cloth by following the movement of the laying device 3. When the rotating disk 3031 rotates, because one end part penetrates and protrudes in the laying device 3, this part will fit onto one side of the flattening block 305. Then, due to the tooth marks on the protruding part of the rotating disk 3031 meshing with the conveyor belt 3052 on the flattening block 305, when the rotating disk 3031 rotates, it will drive the conveyor belt 3052 to rotate and move along the flattening block 305. When the conveyor belt 3052 rotates and moves, it will drive the abutting blocks 3053 on the surface to abut against the surface of the waterproof cloth and move to one side. Through the movement and pulling of the abutting blocks 3053 on both sides of the two flattening blocks 305, a certain pulling force is exerted on the waterproof cloth, so as to flatten the overlapping or deformed and protruding parts during covering, and prevent the waterproof cloth from having partial water accumulation and poor waterproof effect due to some wrinkles, overlaps, and protrusions not being completely attached to the concrete layer.

[0032] The following is the specific implementation process of the present invention. First, the bench 2 is pushed into the tunnel 1, and then the motor on the laying device 3 is turned on to drive the driving roller 304 to rotate. Through the rotation of the driving roller 304, it meshes and rotates along the rack in the displacement groove 202 of the slide rail 201, thereby driving the laying device 3 to move along the slide rail 201. When the laying device 3 moves along the slide rail 201, the waterproof cloth will be covered on the concrete layer on the inner wall of the tunnel 1 through the laying roller 3011 on the middle connecting frame 301, without the need for construction workers to cover and connect the waterproof cloth at the high place of the tunnel 1. At the same time, when the laying roller 3011 lays out the waterproof cloth, the laying frame 302 on one side of the top of the laying device 3 will fit onto the surface where the waterproof cloth has been laid. Then, through the articulated torsion spring connection of the laying frame 302, pressure will be applied to the surface of the laid waterproof cloth, and then it will move while applying pressure on the surface of the waterproof cloth following the movement of the laying device 3, so as to make the adhesion of the waterproof cloth more stable. At the same time, when the laying frame 302 deflects and abuts against the waterproof cloth, the deflecting frame 303 connected by the articulated block 2021 on one side will also deflect to one side through the torsion spring and fit onto the waterproof cloth. When the deflecting frame 303 approaches and fits the waterproof cloth, it will abut against the waterproof cloth through the rotating disks 3031 on both sides, and then rotate and roll on the waterproof cloth by following the movement of the laying device 3. When the rotating disk 3031 rotates, because one end partially protrudes into the laying device 3, this part will fit onto one side of the flattening block 305. Then, due to the tooth marks meshing with the side of the conveyor belt 3052 on the protruding part of the rotating disk 3031 and the flattening block 305, when the rotating disk 3031 rotates, it will drive the conveyor belt 3052 to rotate and move along the flattening block 305. When the conveyor belt 3052 rotates and moves, the abutting block 3053 on its surface will abut against the surface of the waterproof cloth and move to one side. Through the movement and pulling of the abutting blocks 3053 on the two flattening blocks 305 to both sides, a certain pulling force is applied to the waterproof cloth, so as to flatten the overlapping or deformed and bulging parts during covering, and prevent the waterproof cloth from having wrinkles, overlaps and bulges in some parts and not fully fitting the concrete layer, resulting in water accumulation in some parts and poor waterproof effect.
