Abstract
Description
Technical Field
[0001] The invention discloses a tunnel wall seepage drainage structure, which is used for tunnel wall seepage drainage and belongs to the technical field of seepage drainage structures. Background Art
[0002] Tunnels or caverns include a primary lining, a waterproof layer, and a secondary lining. The primary lining is primarily used to stabilize the surrounding rock and prevent deformation and collapse after tunnel excavation. The primary lining is typically composed of shotcrete, anchor rods, steel arches, mesh, and the like. A waterproof layer is placed between the primary and secondary linings to prevent groundwater from seeping into the tunnel, ensuring dryness and safety. The waterproof layer can be in the form of a waterproof sheet, a coating, or a roll. The secondary lining, or permanent lining, is a concrete or reinforced concrete structure applied after the primary and waterproof layers. The secondary lining not only further supports the surrounding rock but also facilitates the installation of tunnel decoration, ventilation, lighting, and other facilities.
[0003] Leakage points are prone to occur on the walls of tunnels or caverns. In the prior art, when leakage occurs in the secondary lining layer, a seepage drainage structure is set up by slotting the secondary lining layer. The seepage water is collected through a water receiving box and connected to the water receiving box through a soft impermeable pipe (drainage pipe) to collect the seepage water. However, the existing seepage drainage structure has the following technical problems:
[0004] 1. When the area of the water seepage point is too large, it cannot be applied to the drainage of a large area of water seepage points, resulting in poor drainage effect;
[0005] 2. The sealing effect of the contact side between the water box and the cave wall is poor, which may easily cause the seepage water to be unable to be discharged from the drainage pipe. Utility Model Content
[0006] The purpose of the utility model is to provide a cave wall seepage drainage structure to solve the problem that the existing technology cannot be applied to the drainage of large-area seepage points when the area of the seepage points is too large, resulting in poor seepage drainage effect.

[0013] When the water receiving box is installed on one side of the top surface of the cave wall, the box body has only one top opening on the top surface, and the mounting plate is arranged on either side opposite to the top opening;
[0014] Located on the opening side of the box body, a filtering structure is provided on the box body.
[0015] Furthermore, the filtering structure includes a double-layer filter screen provided on the box body, and a permeable geotextile A provided between the double-layer filter screen;

[0041] Example 1
[0042] In order to solve the problem that the existing technology cannot be applied to drainage of large-area water seepage points when the water seepage point area is too large, resulting in poor drainage effect. Figure 1-6 As shown, a structure for draining water seepage from a cave wall is provided, comprising a water receiving box 1 and a drainage pipe 2 connected to the water receiving box 1. The water receiving box 1 comprises a box body 3 that cooperates with the cave wall to receive seepage water, a mounting plate 5 with mounting holes 4 disposed on the box body 3, and a diversion structure 6 disposed on the water receiving box 1 for diverting water seeping around the water receiving box 1. The diversion structure 6 comprises a main diversion hose 7 disposed on the water receiving box and branch diversion hoses 8 connected to the main diversion hose 7. On the sides in contact with the cave wall, the main diversion hose 7 and the branch diversion hoses 8 are provided with diversion holes 9. The water receiving box 1 can be made of stainless steel, and the box body 3 can be a square or triangular structure, etc., depending on the actual location and needs.
[0043] In practice, if water seepage occurs on the inner wall of a tunnel or cavern, grooves are cut in the secondary lining layer at the corresponding water seepage position, including an installation groove for installing a water receiving box and a groove along the leakage path around the installation groove. The water receiving box is fixed to the cave wall by wire nails, etc., and then the surrounding gaps are filled with quick-setting waterproof cement mortar for sealing. At the same time, the main diversion hose 7 and the branch diversion hose 8 are arranged in the grooves of the leakage path, and one side of the diversion hole 9 is in contact with the cave wall to ensure water seepage diversion (which can be fixed by permeable concrete). The side without the diversion hole 9 can be fixed to the cave wall by sealing quick-setting waterproof cement mortar, of course, it can also be other waterproof materials. This embodiment provides a diversion structure on the box body, which facilitates the layout of the main diversion hose and the branch diversion hose on the water seepage path around the box body, so that the seepage water can be collected in the main diversion hose and the branch diversion hose through the diversion holes on the main diversion hose and the branch diversion hose, and discharged through the box body and the drainage pipe. This not only reduces the installation of the water receiving box, but also is effectively applicable to the drainage of large-area water seepage points, thereby improving the adaptability and drainage efficiency of large-area water seepage points.
[0044] Example 2
[0045] Based on Example 1, the water collection box 1 is provided with multiple connectors A10, to which the main diversion hose 7 is movably connected; the main diversion hose 7 is provided with multiple connectors B11, to which the branch diversion hoses 8 are movably connected. Connectors A10 and B11 can be externally threaded connectors, and the main diversion hose 7 and branch diversion hoses 8 can be provided with internally threaded connectors that match the externally threaded connectors. Connectors A10 and B11 can also be plug connectors for inserting the main diversion hose 7 and branch diversion hoses 8, and fastened with hoops. The main diversion hose in this embodiment is movably connected to the connector A, and the branch diversion hose is movably connected to the connector B, so that the main diversion hose and the branch diversion hose can be respectively installed on the optimal connector A and connector B according to different leakage paths, so as to facilitate the drainage of seepage. The unused connectors A and B can be directly sealed, and can be sealed by using a sealing cover or other methods. Therefore, the method of setting up connectors A and B can be flexibly adjusted according to the position and flow rate of the actual seepage point to adapt to different seepage conditions.
[0046] Example 3
[0047] Based on Example 2, when the water collection box 1 is installed on the side of the cave wall, the box body 3 has a side opening, and the mounting plate 5 is located on the side opposite the side opening; or when the box body 3 has a side opening and a top opening on the top surface, the mounting plate 5 is located on the side of the side opening and on the side opposite the top opening; when the water collection box 1 is installed on the top surface of the cave wall, the box body 3 has only a top opening on the top surface, and the mounting plate 5 is located on either side opposite the top opening. The opening pattern on the box body is limited according to the installation position of the box body, the purpose is to enhance the applicability of the box body. On the side of the opening of the box body 3, a filter structure 12 is provided on the box body 3 to effectively filter impurities and prevent clogging of the drainage pipe during the drainage process.
[0048] Example 4
[0049] Based on Example 3, the filtration structure 12 includes a double-layer filter screen 13 mounted on the housing 3 and a permeable geotextile A 14 positioned between the double-layer filter screen 13. The diversion structure 6 also includes a permeable geotextile B 15 sleeved over the main diversion hose 7 and the branch diversion hose 8. The filtration structure, including the double-layer filter screen and permeable geotextile A, effectively filters out fine particulate matter, ensuring clean seepage water enters the housing and exits through the drainage pipe. The permeable geotextile B prevents clogging not only of the diversion holes but also of the drainage pipe, thereby extending the service life of the structure.
[0050] Example 5
[0051] On the basis of Example 4, the mounting plate 5 and the box body 3 adjacent to the mounting plate 5 are provided with a groove 16, and a sealing strip 17 is provided in the groove. Figure 1 、 2 As shown, the sealing strip 17 is an annular sealing strip, as shown in FIG. Figure 3 、 4 The figure shows a U-shaped sealing strip with an opening on one side of the top. The groove and sealing strip are placed inside the groove to ensure a tight seal between the contact surface between the water collection box and the hole wall. When installed with the water collection box, the sealing material on the edge is matched to effectively reduce the possibility of box leakage, ensuring that the leaking water can be discharged through the drainage pipe.
