Description

Technical Field

[0001] The present invention relates to the technical field of tunnels, and in particular to a water supply and drainage installation system in a tunnel. Background Art

[0002] Generally, railway tunnels constructed by TBMs have a herringbone slope. The TBMs are driven against the slope and drain water down the slope. Sewage in the tunnel is generally discharged by gravity through the central ditch on the invert block, and clean water seeping out of the tunnel walls is drained down the slope through the trenches on both sides. However, some railway tunnels use down-slope excavation and reverse-slope drainage. The reverse-slope drainage pump station is located on one side, so the drainage pipes can only be arranged for single-sided pumping and drainage, and a clean and dirty water diversion method is also used. When there is a large influx of water in the tunnel, multiple large-diameter steel pipes are required for drainage. Usually, the drainage pipes are arranged on the tunnel wall. When the lining trolley passes, the section of steel pipe that interferes with the lining trolley can only be temporarily removed and connected with a hose or other form of transition. After the lining concrete is completed and the lining trolley has left, the pipes need to be restored, which is very troublesome. Summary of the Invention

[0042] like Figure 1 As shown, the water supply and drainage installation system in a tunnel provided by the present invention is used for laying water supply and drainage pipes in a tunnel, and includes:

[0043] Tracks are arranged along the tunnel. They can be used not only for the movement of transport vehicles but also for the movement of lining trolleys.

[0046] The transport vehicle 200 has a flat plate support 210 arranged along the track direction and capable of carrying the pipeline. Two swivel support columns 220 are provided on the transport vehicle inside the flat plate support 210. A swivel drive mechanism and a swivel arm 230 are provided on the top of the swivel support column 220. The swivel drive mechanism 240 can drive the swivel arm 230 to rotate in a horizontal plane. When the swivel arm 230 rotates to be perpendicular to the track direction, the end of the swivel arm 230 is located above the pipeline support.

[0047] The rotating arm 230 is provided with a movable hoisting mechanism 231, which can perform reciprocating motion on the rotating arm so as to be able to hoist the pipe carried by the flat plate support to the pipe support;

[0048] The end of the slewing arm 230 is provided with an auxiliary limiting device 250 that can be horizontally extended and retracted, and when the auxiliary limiting device is in an extended state, it can touch the tunnel wall.

[0049] When the slewing arm 230 on the transport vehicle rotates to a direction perpendicular to the track, the auxiliary limiting device 250 at the end of the slewing arm 230 is controlled so that it can touch the tunnel wall, thereby fixing the slewing arm 230 and facilitating the mobile lifting mechanism on the slewing arm 230 to lift the pipeline onto the pipeline support.

[0050] A counterweight block 270 is provided on the transport vehicle on one side of the slewing support column. The counterweight block can keep the entire transport vehicle stable when the mobile lifting mechanism 231 moves to the end of the slewing arm 230, and prevent the transport vehicle from tipping over to one side due to excessive load at the end of the slewing arm.

[0051] A vertical blocking column 260 is provided on the transport vehicle on a side different from the slewing support column.

[0052] The rotary drive mechanism includes a rotary oil cylinder, the bottom of the rotary oil cylinder is connected to the rotary support column, and the top of the rotary oil cylinder is connected to the rotary arm.

[0053] The mobile lifting mechanism includes a self-propelled chain hoist, which can be operated by remote control, thereby reducing work intensity.

[0054] The auxiliary limiting device 250 includes a limiting oil cylinder, a pressure sensor and a fixing bracket. The fixing bracket is connected to the limiting oil cylinder so that the limiting oil cylinder is fixed to the slewing arm. The pressure sensor is arranged at the rear end of the limiting oil cylinder.

[0059] The main cross brace 110 is arranged horizontally in the tunnel near the tunnel wall, and its end near the tunnel wall is connected to the first embedded part 113 on the tunnel wall. The main cross brace 110 is used to provide support for the water pipe. One end of the main cross brace is horizontally fixed to the first embedded part 113 of the tunnel wall, and the other end is supported on the step in the tunnel by the first support arm 120. It is further reinforced by the second support arm 130, which can also disperse the supporting force of the first support arm 120.

[0060] A first support arm 120 is vertically supported at the lower portion of the other end of the main cross brace 110 away from the tunnel wall, and the bottom of the first support arm is connected to the second embedded part 122 of the first step 121 in the tunnel;

[0061] The second support arm 130 is supported at the lower portion of the main cross brace 110 and is located between the two ends of the main cross brace 110 . The bottom of the second support arm 130 is connected to the third embedded part 132 of the second step 131 in the tunnel.

[0062] Optionally, a support 114 is provided on the upper surface of the end of the main cross brace 110 away from the tunnel wall to provide positional support for the steel pipes arranged on the main cross brace 110. The supports 114 are generally arranged in pairs, so as to limit the position of the water pipes from two directions, and the supports usually have an inclined surface;

[0063] Optionally, a secondary cross brace 111 is further included, horizontally connected to the main cross brace 110, and the main cross brace 110 is connected to the first embedded part 113 via the secondary cross brace 111. The design of the secondary cross brace 111 and the connecting cross brace 112 facilitates the connection and fixation of the main cross brace and enables the adjustment of the main cross brace.

[0064] Optionally, the main cross brace 110 and the secondary cross brace 111 are connected by a connecting cross brace 112, and bolt holes are evenly provided on the connecting ends of the main cross brace 110, the secondary cross brace 111 and the connecting cross brace 112 so that they can be fixed to each other by bolt connection.

[0065] Optionally, a telescopic structure 140 is provided in the middle of the first support arm 120 , and the top of the first support arm 120 is rotatably connected to the main cross brace 110 via a first hinge seat 123 .

[0066] Optionally, the second support arm 130 is supported at the lower portion of the main cross brace 110 in an inclined manner.

[0067] Optionally, a telescopic structure 140 is provided in the middle of the second support arm 130 , and the top of the second support arm 130 is rotatably connected to the main cross brace 110 via a second hinge seat 133 .

[0068] The first hinge seat 123 and the second hinge seat 133 can facilitate the fixation and adjustment of the main cross brace 110, avoiding installation difficulties caused by direct fixed connection.

[0069] Optionally, both ends of the telescopic structure 140 are provided with threads, and the threads are rotated in opposite directions; a rotating rod 141 is provided in the middle of the telescopic structure. The length of the first support arm 120 and the second support arm 130 can be adjusted by the telescopic structure 140.

[0070] The drainage pipe system in the excavation tunnel provided by the present invention is arranged along the inside of the tunnel and is directly formed on the tunnel steps on both sides of the lining trolley. It can avoid the lining trolley and allow the lining trolley to reciprocate without removing the bracket and water pipes; at the same time, four drainage pipes are fixed, and the top is obliquely fixed by an oblique chain.
