Currently, multi-layer lining is commonly used, which generally includes: an outer lining such as shotcrete or pipe segments; an inner lining such as steel pipes or PVC pipes; and reinforced concrete or self-compacting concrete filling the space between the outer and inner linings.

[0003] An existing application number is CN201822247329.4, entitled "An Installation Structure for Steel Lining Pipes in a Water Conveyance Tunnel". This utility model discloses an installation structure for steel lining pipes in a water conveyance tunnel. The key technical points of the solution include a support member, an in-tunnel rolling device, and an in-tunnel guide rail device. The in-tunnel rolling device and the in-tunnel guide rail device are spaced apart on the support member. The in-tunnel rolling device includes a pair of earrings symmetrically arranged on both sides of the support member, a steel shaft between the earrings, and a sleeve rotatably arranged on the steel shaft.

[0004] The above-mentioned utility model structure addresses the problem of low efficiency in the installation and transportation of steel pipes inside straight tunnels. However, the shortcomings of this structure are that the steel pipes are prone to falling off during the installation and transportation process inside the tunnel, and the dusty environment inside the tunnel can easily cause the shaft to become clogged. Therefore, a steel pipe installation structure for water conveyance tunnel lining is proposed. Utility Model Content

[0023] The screw groove plate 15 is located in the middle between the side plates 11. The screw groove plate 15 has a plurality of grooves. The structural fixing plate 4 has a fixing protrusion 42. The fixing protrusion 42 has holes and fixing bolts are provided to pass through the fixing protrusion 42 and be screwed into the grooves on the screw groove plate 15.

[0024] The structural fixing plate 4 is provided with a structural fixing vertical plate 41, and the structural fixing vertical plate 4 and the structural fixing plate 4 are at a right angle to each other. The structural fixing plate 4 and the structural fixing vertical plate 41 are fixed on the guide rail inside the tunnel.

[0025] The structural fixing plate 4 and the structural fixing vertical plate 41 are fixed on the guide rail inside the tunnel. The fixing bolts pass through the fixing protrusion plate 42 and the screw groove plate 15 to connect and fix the structural fixing plate 4 and the mounting plate 1, thereby fixing the mounting plate 1 to the guide rail and fixing the position of the mounting plate 1.

[0026] The inclined plate 13 has an inner shaft 14 in the upper plate groove. The top and bottom of the inner shaft 14 are fixed in the upper and lower plate groove of the inclined plate 13. The inner shaft 14 has a first rotating sleeve 2, and the surface of the first rotating sleeve 2 has a smooth surface.

[0027] Inclined plates 13 are set on both sides of the top of the mounting plate 1. The inclined plates 13 enclose the steel pipes passing on the mounting plate 1 to prevent the steel pipes from moving off the top of the mounting plate 1. The first rotating sleeve 2 set on the inclined plates 13 facilitates the movement of the steel pipes after contact, reducing the friction between the steel pipes and the inclined plates 13.

[0028] The connecting shaft plate 12 has holes, and a mounting shaft 31 is provided between the connecting shaft plates 12.

[0031] The reinforcing plate 16 improves the overall structural strength of the mounting plate 1.

[0032] The working principle and usage process of this utility model are as follows: The structural fixing plate 4 and the structural fixing vertical plate 41 are fixed on the guide rail inside the tunnel. The fixing bolts pass through the fixing protrusion plate 42 and the screw groove plate 15 to connect and fix the structural fixing plate 4 and the mounting plate 1, thereby fixing the mounting plate 1 to the guide rail and fixing the position of the mounting plate 1. The reinforcing plate 16 improves the overall structural strength of the mounting plate 1. The second rotating sleeve 3 set on the mounting plate 1 reduces the friction of the steel pipe on the mounting plate 1, thereby facilitating the movement of the steel pipe. The steel pipe pushing device at the tunnel entrance pushes... The movement of the rotating sleeve 3 reduces the friction of the steel pipe inside the tunnel. The rotating shaft 31 and the connecting shaft plate 12 are also rotatably connected, so that even if the rotating sleeve 3 is blocked, the rotating shaft 31 can still rotate to ensure the transportation of the steel pipe. The inclined plate 13 is set on both sides of the top of the mounting plate 1. The inclined plate 13 is used to block the steel pipe passing on the mounting plate 1 to prevent the steel pipe from moving off the top of the mounting plate 1. The first rotating sleeve 2 set on the inclined plate 13 facilitates the movement of the steel pipe after contact and reduces the friction between the steel pipe and the inclined plate 13.
