Description

Technical Field

[0001] The utility model relates to the technical field of tunnel drainage, in particular to a tunnel water seepage control structure. Background Art

[0002] Tunnels often face various structural and functional problems during long-term operation. Especially for tunnels with a long operating time, water leakage has become a key challenge affecting their structural integrity and safety. For example, a tunnel had serious water leakage after about 20 years of operation, which manifested in various forms such as lining voids, lining seepage, lining cracks and poor quality of tunnel vault concrete.

[0003] The tunnel is located in an area with complex geological conditions, with poor surrounding rock integrity and high permeability. The groundwater is abundant, and especially during the rainy season, the groundwater level rises, causing water to flow along the cracks in the surrounding rock to the tunnel perimeter. Frequent seismic activity also exacerbates this problem, destroying the tunnel surrounding rock structure and inducing new diseases.

[0004] In addition, the tunnel’s drainage system design was flawed, and long-term inadequate maintenance led to the overall failure of the system. The drainage blind pipes and drainage holes gradually became clogged due to the long-term precipitation and crystallization of calcium bicarbonate groundwater. This failure of the drainage system not only exacerbated the water leakage problem, but also posed a threat to the overall structural integrity of the tunnel.

[0005] Therefore, in the face of this series of problems, a new technical solution is urgently needed that can not only effectively control the water leakage problem in the tunnel, but also prevent the development of future diseases and ensure the long-term safety and reliable operation of the tunnel.

The filter layer 6 can be composed of multiple layers of gauze (or other materials), and its aperture decreases from top to bottom, so that granular impurities of different sizes can be filtered, and an arc-shaped water guide pipe 9 is equidistantly arranged between the anti-seepage cloth 5 and the filter layer 6, and a plurality of groups of water permeable holes 7 are equidistantly opened on the water guide pipe 9, and the number can be six, eight, etc., according to actual conditions, and the water guide pipe 9 (whose shape is semicircular, which can conveniently guide the preliminarily filtered water into the sedimentation tank 13 of the filtering mechanism, which is a relatively mature technology and will not be described here), the bottom of the water guide pipe 9 is symmetrically provided with two water outlets 10, and the water outlets 10 extend into the sedimentation tank 13.

[0025] See also Figure 1-Figure 5 In order to better perform the filtering operation and reduce the burden of the filter 18, cavities are opened at both ends of the road surface 2, and the cavity is divided into a sedimentation tank 13 and a filter tank by a partition 16, so that water can be conveniently introduced into the sedimentation tank 13 for sedimentation, and a filter plate 17 is provided on the partition 16, which can filter the precipitated water and then enter the filter tank, and then filter it through the filter 18 inside it, and a drain pipe 3 is provided in the middle of the bottom end of the road surface 2, and the drain pipe 3 is connected to the filter tank through a connecting pipe 12, so that the filtered water can be conveniently discharged through the connecting pipe 12 and the drain pipe 3.

[0026] See also Figure 1-Figure 5 In order to drain the water on the road surface 2, grilles 4 can be plugged into the two ends of the road surface 2, which can facilitate the water on the road surface 2 to enter the cavity and prevent impurities such as stones from entering the interior. An inclined plate 11 is provided at the top of the cavity to facilitate the water to flow into the sedimentation tank 13, and the tops of the partitions 16 and the filter screen 18 are both connected and fixed to the inclined plate 11. In order to facilitate the subsequent discharge of impurities at the bottom of the cavity and the discharge of water from the drain pipe 3, a second guide plate 15 is provided at the bottom of the cavity, and a first guide plate 14 is provided at the bottom of the drain pipe 3 (both guide plates are connected to the bottom of the cavity).

The grille 4 can prevent impurities from entering the interior. After the water is precipitated in the sedimentation tank 13, it flows into the filter tank through the filter plate 17, and then passes through the filter screen 18 for filtration, and then flows to the drain pipe 3 through the connecting pipe 12 for discharge. After a period of use, when it is necessary to flush the filter tank, sedimentation tank 13, etc., water is introduced through the water inlet pipe 19 and sprayed through the flushing nozzle 8 under the flushing pipe 20, The filter plate 17, the filter screen 18, the filter tank and the sedimentation tank 13 can be flushed, and the impurities and water flow out with the first guide plate 14 to achieve the flushing effect. The flushing operation can be performed regularly to ensure the filtering effect, prevent blockage, and improve the reliability in long-term use.
