[0002] In recent years, with the rapid development of transportation construction, the number of tunnels and underground projects being built has been increasing. During tunnel construction, it is necessary to drain water-rich sections of the tunnel.
[0003] Because of the high water content in the water-rich section, a large amount of water will always flow into the tunnel when the drainage pipe is under maintenance. This makes subsequent treatment difficult and excessive water flow can easily cause safety hazards. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figure 1 As shown, a drainage device for a water-rich section of a tunnel includes: a base 1; a drain pipe 2 disposed on the base 1; a drain pipe 3 connected to the drain pipe 2; a transfer device 4 disposed between adjacent drain pipes 2; a branch pipe 5 slidably connected to the top of the transfer device 4, wherein a water passage 51 is provided in the branch pipe 5; a limiting component 6 disposed on the transfer device 4, wherein the limiting component 6 limits the height of the branch pipe 5; and a temporary connecting pipe 7 connecting adjacent branch pipes 5.
[0024] The base 1 includes a concrete base 11 and a support frame 12. The concrete base 11 is poured during tunnel construction, and the support frame 12 is pre-embedded in the concrete base 11. The position and support height of the support frame 12 are determined by the concrete base 11. The top of the support frame 12 supports the drain pipe 2. The support frame 12 can restrict the rotation of the drain pipe 2 and facilitates positioning and quick installation when installing the drain pipe 2.
[0025] Drainage pipe 3 is located on the side wall of drainage pipe 2. Drainage pipe 3 extends into the rock wall of the water-rich section of the tunnel. The drainage pipe 3 collects the seepage water in the tunnel into drainage pipe 2 for centralized discharge, ensuring the safety of the tunnel. Drainage pipe 3 includes a horizontal pipe 31 and a vertical pipe 32. The vertical pipe 32 is perpendicular to the horizontal pipe 31 and is used to collect water flowing vertically. In other embodiments, it can be made into an arc-shaped pipe with the same curvature as the tunnel. The horizontal pipe 31 is used to collect water from the thicker rock wall. The horizontal pipe 31 is inclined. The end of the horizontal pipe 31 away from the drainage pipe 2 is close to the end of the drainage pipe 2. The water collected by the horizontal pipe 31 and the water flowing into the horizontal pipe 31 from the vertical pipe 32 automatically flow into the drainage pipe 2 for discharge through the inclined angle.
[0026] The sidewalls of the horizontal pipe 31 and the longitudinal pipe 32 are provided with water inlet holes 33. Water in the water-rich section of the tunnel enters through the water inlet holes 33, preventing rocks from entering the horizontal pipe 31 or the longitudinal pipe 32 and causing blockage due to accumulation.
[0027] Drain pipe 2 can drain water outwards by gravity or by a water pump to pressurize and accelerate the discharge. The specific method used depends on the seepage rate.
[0028] The drain pipe 2 passes through several transfer devices 4 during drainage, such as... Figure 2As shown, the lower part of the converter 4 is provided with a mounting hole 41, and the end of the drain pipe 2 is located in the mounting hole 41. The adjacent drain pipe 2 is connected by the mounting hole 41. The top of the converter 4 is provided with an operation hole 42, which is vertically downward and is connected to the mounting hole 41. The converter 4 is also provided with an equipment slot 43, which is a downward extension of the operation hole 42. The equipment slot 43 is located below the mounting hole 41 and can be used to support the bottom of the water distribution pipe 5.
[0029] The water distribution pipe 5 is slidably connected to the operating hole 42. The top of the water distribution pipe 5 is located above the converter 4. The water passage 51 is L-shaped, with its upper opening located at the top of the water distribution pipe 5 and its lower opening located on the lower side wall of the water distribution pipe 5. When the bottom of the water distribution pipe 5 enters the equipment tank 43, the lower part of the water passage 51 connects with the mounting hole 41, at which point the mounting hole 41 is closed, and water can only flow into the water passage 51. After closing the two mounting holes 41, the drain pipe 2 between the two corresponding converters 4 can be inspected and repaired.
[0030] The top side wall of the water distribution pipe 5 is provided with a handle 53, which can lift the water distribution pipe 5 upward. When the bottom of the water passage 51 is above the mounting hole 41, the water flow cannot enter the mounting hole 41 and the operation hole 42.
[0031] The top of the transceiver 4 is provided with multiple support grooves 44, which face the four directions of front, back, left and right. The upper part of the water distribution pipe 5 is provided with an indicator post 52, which is located above the bottom outlet of the water passage 51. This allows for quick determination of the water inlet and outlet direction of the water distribution pipe 5. When the bottom of the water distribution pipe 5 enters the equipment groove 43, the indicator post 52 is installed in the support groove 44. The support groove 44 restricts the water distribution pipe 5 from rotating freely, thereby keeping the water outlet direction of the water distribution pipe 5 unchanged.
[0032] During normal drainage, the limiting component 6 restricts the downward movement of the water distribution pipe 5, keeping the mounting hole 41 unobstructed. For example... Figure 3 As shown, the limiting component 6 includes a support frame 61 and a limiting rod 62. The support frame 61 is located above the transducer 4, with one end open. The limiting rod 62 can be inserted into the support frame 61. If the indicator post 52 is above the support frame 61 and the limiting rod 62, the limiting rod 62 and the support frame 61 restrict the downward movement of the indicator post 52, thereby preventing the water distribution pipe 5 from obstructing normal drainage. The limiting rod 62 and the support frame 61 are connected by bolts 63. When disassembling the limiting rod 62, a hand drill can be used to remove and install the bolts 63. After removing the limiting rod 62, the water distribution pipe 5 can be moved downward to connect the water passage 51 with the mounting hole 41. When the indicator post 52 is below the limiting rod 62, its rotation will not be obstructed by the support frame 61.
[0033] The temporary connector 7 is used for normal drainage during maintenance. Both ends of the temporary connector 7 can be inserted into the top of adjacent water passages 51. The end of the temporary connector 7 is equipped with an extension piece 71, the diameter of which is larger than the diameter of the water passage 51. The extension piece 71 is used to support the temporary connector 7 on the branch pipe 5. When maintaining or replacing the drain pipe 2, the bottom of one water passage 51 faces the inlet end, and the bottom of the other water passage 51 faces the outlet end. The temporary connector 7 is then installed above the two water passages 51 to achieve temporary drainage, allowing maintenance work to be carried out without affecting the drainage of the water-rich section.
[0034] Since temporary connection 7 requires water to flow upwards, a water pump can be used to help lift the water.
[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
