Description

Technical Field

[0001] This application relates to the field of water conservancy engineering equipment technology, and in particular to a TBM water conveyance tunnel lining steel pipe installation and transportation equipment and transportation and installation method. Background Technology

[0002] In water diversion projects, water conveyance tunnels are an important component. More and more water conveyance tunnels are being constructed using the TBM method. After the TBM excavation is completed, the tunnel has a circular cross-section. Steel pipes are installed inside the excavated tunnel, and self-compacting concrete is filled between the steel pipes and the surrounding rock or tunnel segments to form a water-passing cross-sectional structure with an inner steel pipe lining.

[0003] To save costs, the distance between the tunnel lining steel pipe and the surrounding rock or segments is generally small, usually 30-50cm, and the working space outside the steel pipe is narrow. The diameter of the lining steel pipe is generally 2.5-5m, and a single steel pipe is 6-12m. The large diameter, heavy weight and long length of the steel pipe make installation difficult in a limited space, and it is difficult for general mechanical equipment to transport and hoist the steel pipe.

[0004] Currently, the installation of steel lining pipes in the water conservancy industry is usually carried out using a special pipe-laying machine. The pipe-laying machine needs to be customized according to the diameter of the steel pipe, and the production cycle is long. The cost of the pipe-laying machine is high. The amortization cost of installing steel pipes with a single pipe-laying machine is generally more than 5 kilometers.

[0025] To address the aforementioned issues, this application provides an installation and transportation device and method for steel pipe lining in a TBM water conveyance tunnel. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 and Figure 12 The TBM water conveyance tunnel lining steel pipe installation and transportation equipment shown includes a rail transportation system 1, which is used to transport the steel pipe to the drill-blast tunnel section. Transfer system 2 is used to transfer steel pipes from the drill-and-blast tunnel section to the segment tunnel section, and remove the steel pipe supports of the track transport system 1 during the transfer process. Wheel transport system 3 is used to transport steel pipes within the segment tunnel section to the end of the lined section and to install and connect them with the installation docking device 4. Install docking device 4, which is used for the installation of steel pipe at the end of the lining section; Temporary support steel section 5 is used for temporary support of the pipeline during lining installation; The track transport system 1 is located in the drill-and-blast tunnel section, and the transfer system 2 is located at the junction of the drill-and-blast tunnel section and the segment tunnel section; the wheel transport system 3 is installed on the pipeline, and the docking device 4 is installed at the end of the lined section; the track transport system 1 and the transfer system 2 share the same set of tracks at the junction.

[0027] In this application, the steel pipe to be installed is transported horizontally from outside the tunnel to the drill-and-blast tunnel section at the entrance of the TBM tunnel via a rail transport system 1. A transfer system 2 is set up at the entrance of the TBM tunnel to transfer the steel pipe from the drill-and-blast tunnel section to the segment tunnel section. During the transfer, the steel pipe support of the rail transport system 1 is removed. The steel pipe to be installed is unloaded onto the transfer platform using the transfer system 2. Then, the steel pipe is transported from the transfer platform to the installation position via a wheel transport system 3. The installation docking device 4 is used to position and weld the steel pipe to be installed. Finally, a temporary support device is set up on the outside of the installed steel pipe to fix the steel pipe and provide the installation conditions required for the next section of steel pipe.

[0028] This invention achieves the in-tunnel transportation of inner lining steel pipes through a rail transport system 1, a transfer system 2, and a wheeled transport system 3. It uses an installation docking device 4 and temporary support steel 5 to achieve precise docking of the steel pipes, solving the problem of installing inner lining steel pipes in short-distance water conveyance tunnels. The steel pipe transportation and installation construction costs are low, and the construction quality, safety, and progress are guaranteed, making it widely applicable.

[0029] In one embodiment, such as Figure 2 and Figure 3 As shown, the rail transport system 1 includes an elevated support frame 11, a track 12, a flatbed 13, and a steel pipe support 14. Among them, the bottom of the flat plate 13 is provided with track wheels 131 to form a flat plate track trolley; A support frame 11 is installed inside the arc-shaped guide platform of the tunnel to fill the arc-shaped guide platform surface. Two parallel rails 12 are installed on the support frame 11. A flat rail trolley is installed on the rails 12. A steel pipe support 14 is placed on the flat rail trolley, and steel pipes are installed on the steel pipe support 14. The steel pipe support 14 includes a main support plate 141, a secondary support plate 142, a limiting plate 143, and a reinforcing plate 144. The main support plate 141 and the secondary support plate 142 are detachably and fastened together to form a total support plate by bolts. Limiting plates 143 are fixedly installed at both ends of the total support plate, and reinforcing plates 144 are installed between the end of the limiting plate 143 and the surface of the total support plate.

[0030] In this application, the steel pipe support adopts a detachable structure with screw connections, broken off at one-quarter of its length, and fitted with a connecting plate. This connection is achieved via bolts, facilitating subsequent disassembly. The support plate length is greater than half the diameter of the steel pipe, ensuring stable transport of the steel pipe. Both the flatbed trolley and the locomotive travel on rails made of 43kg / m steel rails, with the wheel track matching the rail spacing. The trolley width is 1.2m. The locomotive and two trolley sections are used in combination, with the total length of the trolley ensuring that the overhang length at both ends of the steel pipe does not exceed 1m. Four steel pipe supports are used in combination, placed on the flatbed trolley, with blocks on both sides, 10-20cm high, to prevent the supports from tipping over.

[0031] In one embodiment, such as Figures 4 to 8 As shown, the transfer system 2 includes outriggers 21, crossbeams 22, and a steel platform 23; The support frame 11 has multiple support legs consisting of legs 21 and crossbeams 22 on both sides of the track 12. The crossbeams 22 are fixedly mounted on the top of the legs 21. A steel platform 23 is mounted on the support legs, and slots 24 are constructed at intervals on the steel platform 23. The slots 24 are located on the ground on both sides of the support frame 11. A vertical lifting cylinder 25 is installed directly below the slots 24. The steel platform 23 is broken into sections at the slots 24. A fixed longitudinal beam 26 for the vertical crossbeams 22 is installed at the bottom of the steel platform 23. A movable longitudinal beam 27 is installed between the two fixed longitudinal beams 26 at the slots 24. One end of the movable cover plate 28 is located on the movable longitudinal beam 27, and the other end has a support leg 21 mounted on it.

[0032] In this application, the outriggers 21, crossbeams 22, and fixed longitudinal beams 26 are all made of structural steel, while the steel platform 23 is made of steel plate. All these components are welded together to form a stable whole. Support frames 11 and outriggers 21 are installed at intervals of 1-2 meters along the longitudinal direction of the tunnel. The crossbeams 22 are positioned perpendicular to the tunnel axis and located on the upper part of the outriggers 21. The fixed longitudinal beams 26 are located at the tangent point of the circle formed by the steel wheels at the bottom of the steel pipe. Hydraulic jacks or vertical lifting cylinders 25, used for vertical lifting, are positioned corresponding to the positions of the four supports on the track. A total of eight jacks are installed in four groups, with one cylinder at each end of each support. Simultaneous lifting is achieved through a hydraulic pump station. The steel platform 23 has an opening 24 corresponding to the position of the vertical lifting cylinder. A movable longitudinal beam 27 is installed at the opening and inserted into the fixed longitudinal beam 26. A movable cover plate 28 is installed on the fixed longitudinal beam 26. The vertical lifting cylinder can lift the support on the flatbed truck through the opening, raising the steel pipe below.

[0033] In one embodiment, such as Figures 9 to 11 As shown, the wheeled transport system 3 includes a traction steel beam 31, a roller frame 32, rollers 33, a traction rope 34, a traction machine 35, and a guide pulley 36. The system includes a traction steel beam 31 installed inside the end of the steel pipe, a traction machine 35 installed at the end of the lining section, a traction rope of the traction machine 35 connected to the traction steel beam 31, a roller frame 32 installed at the bottom of the steel pipe, rollers 33 installed on the roller frame 32, and a rotatable guide pulley 36 fixed on the tunnel sidewall by an adjustable length steel wire rope.

[0034] In this application, the traction steel beam 31 is located at the front end inside the steel pipe to be installed. A lifting lug is installed in the middle of the traction steel beam 31. Three sets of steel wheels, serving as rollers 33, are evenly arranged along the longitudinal direction of the steel pipe at the bottom outside. The rated load capacity of the steel wheels is 10t, with a total of 6 rollers in 3 sets. The height of the steel wheel set at the tail end of the steel pipe is 2-3cm less than the thickness of the outer concrete lining. The height of the two sets of steel wheels in the middle and front ends of the steel pipe is 1-2cm lower than that at the tail end. The front set of steel wheels is a 30° steerable steel wheel, while the middle and tail sets are directional steel wheels, facilitating the movement and docking of the steel pipe in tunnels with curves. A winch or traction machine 35 is located inside the tunnel in front of the inner lining steel pipe. The traction rope 34 of the winch or traction machine 35 is connected to the lifting lug using a U-shaped shackle. The winch or traction machine 35 pulls the steel pipe forward within the TBM tunnel to the installation position.

[0035] This application also installs guide pulleys 36 at intervals of 10-15m at tunnel bends. The guide pulleys 36 are fixed to the tunnel sidewall by steel wire ropes of adjustable length. When the winch pulls the steel pipe, the position of the steel pipe is corrected by adjusting the length of the steel wire rope of the guide pulleys 36 to ensure that the axis of the steel pipe coincides with the axis of the tunnel.

[0036] In one embodiment, the flatbed track trolley is located between the two steel platforms 23, the fixed longitudinal beam 26 is located on top of the inner support leg 21, and the roller 33 is located above the fixed longitudinal beam 26, which facilitates the removal of the flatbed track trolley during the transportation of the steel pipe and the installation.

[0037] In one embodiment, such as Figure 12 As shown, the installation docking device includes a Z-shaped lifting frame and an electric hoist. The Z-shaped lifting frame consists of an upper boom, a bottom frame, and connecting columns, all welded from structural steel. A 20t electric hoist is suspended at the front end of the upper boom. The temporary support steel section 5 consists of 8 steel sections evenly spaced at 45° intervals on the outer side of the tail of each steel pipe section, supporting the surrounding rock or pipe segments to fix the steel pipe.

[0038] In one embodiment, a method for transporting and installing the steel lining pipe of a TBM water conveyance tunnel utilizes the TBM water conveyance tunnel steel lining pipe installation and transportation equipment described in any of the above embodiments. Specifically, the installation method is as follows: 1) Installation of each beam: Install the steel pipe transfer system 2 at the TBM tunnel entrance, install the support frame 11, support legs 21, connecting crossbeams 22, and fixed longitudinal beams 26 in sequence, lay a steel platform 23 on the upper part of the crossbeams 22 and fixed longitudinal beams 26, set the opening slots 24 of the vertical lifting cylinders on the steel platform 23 at the required intervals, and detach the movable longitudinal beams 27 and movable cover plates 28 from the steel platform; 2) Guided traction installation: Install a winch or traction machine 35 in the tunnel in front of the steel pipe to be installed, and arrange the wire rope and wire rope guide pulley 36. 3) Installation of traveling steel wheels: The bottom traveling steel wheels of the steel pipe to be installed are welded outside the hole, and the traction steel beam 31 is welded to the front end of the inside of the steel pipe.

[0039] 4) Steel pipe hoisting and transportation: Two flatbed railcars and one locomotive are grouped together. Steel pipe supports 14 are set on the flatbed railcars. The steel pipes to be installed are hoisted onto the steel pipe supports 14 on the flatbed car by a crane. The steel pipes to be installed are transported to the steel platform at the entrance of the TBM tunnel by the locomotive and rail. 5) Steel pipe lifting: Start the vertical lifting cylinder of the steel pipe transfer system 2 to lift the steel pipe support 14, which will drive the steel pipe to rise by 5~10cm, so that the steel pipe support 14 is separated from the steel pipe on the flatbed truck. 6) Removing the flatbed truck: The flatbed truck is removed from the tunnel by reverse traction from a locomotive; 7) Force conversion: Activate the vertical lifting cylinder of the steel pipe transfer system 2, lower the steel pipe support 14, drive the steel pipe to fall, so that the steel wheel at the bottom of the steel pipe lands on the steel platform, complete the system conversion from support to steel wheel, and remove the steel pipe support 14 at the bottom of the steel pipe; 8) Opening Cover: Install the movable longitudinal beam 27 and the movable cover plate 28 to the opening on the steel platform; 9) Steel pipe docking and conveying: Connect the winch wire rope to the traction steel beam set at the front end of the steel pipe, start the winch, and pull the steel pipe forward to the installation position; 10) Steel pipe butt hoisting: After the steel pipe arrives at the installation position, the Z-type hoisting frame 41 and electric hoist 42 are used to adjust the position of the front end of the steel pipe up, down and left and right. At the same time, jacks or vertical lifting cylinders are used to adjust the position of the rear end of the steel pipe to complete the steel pipe butt hoisting. 11) Steel pipe welding and fixing: The front end of the steel pipe is welded and fixed to the installed steel pipe, and 8 steel sections are set at the rear end to support the surrounding rock or pipe segments, evenly arranged at 45° intervals to fix the steel pipe. 12) Repeat the above operation to install the subsequent steel pipes.

[0040] This invention enables the in-tunnel transportation of inner lining steel pipes through a rail transport system, a transfer system, and a wheeled transport system. It achieves precise docking of steel pipes by using installation docking devices and temporary support steel sections in combination with appropriate transportation and installation methods. This solves the problem of installing inner lining steel pipes in short-distance water conveyance tunnels.
