Description

Technical Field

[0001] This utility model belongs to the field of bridge and tunnel seepage prevention, specifically relating to a high-efficiency drainage bridge and tunnel seepage prevention structure. Background Technology

[0002] The anti-seepage structure design of bridge tunnels is to prevent water from flowing into the structure and ensure its long-term stability and safety. Anti-seepage is especially important in bridge tunnels that are underground or near water.

[0003] The existing anti-seepage structures for bridge and tunnel pavements mostly rely on laying multiple layers of waterproof structures to prevent rainwater from seeping into the soil at the bottom of the pavement. However, laying multiple layers of waterproof structures is not only costly to construct, but also makes it difficult to fundamentally drain rainwater and prevent it from accumulating and seeping. Furthermore, after long-term use, it often requires multiple and tedious maintenance to ensure the effectiveness of anti-seepage measures for bridge and tunnel pavements.

[0004] Therefore, in response to the existing problems of rainwater being difficult to drain quickly from bridge tunnels during rainy weather and easily accumulating on the road surface, leading to rainwater infiltration, a high-efficiency drainage and seepage prevention structure for bridge tunnels is developed. By adding a high-efficiency drainage structure and a rainwater infiltration prevention structure to bridge tunnels, the effect and efficiency of rainwater drainage from bridge tunnels can be effectively improved, and rainwater accumulation on the road surface inside the bridge tunnel can be avoided, thereby preventing rainwater infiltration. Utility Model Content

[0005] In order to overcome the problem that existing bridges and tunnels have difficulty draining rainwater quickly during rainy weather and that rainwater tends to accumulate on the road surface, leading to rainwater infiltration.

An asphalt pavement, a buffer layer, an infiltration layer, and a waterproof adhesive layer are installed sequentially from top to bottom in the fifth channel. A bottom storage hopper is fixed to the lower end of the tunnel pavement body. A water pump is installed in the bottom storage hopper.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1-7This utility model provides an embodiment: a high-efficiency drainage bridge tunnel seepage prevention structure, including a tunnel pavement body 3, a filter box 6, a filter screen 7, a bottom storage hopper 4, and a water pump 21. A fifth groove 14 is provided through the center of the upper end of the tunnel pavement body 3. A first groove 8 is symmetrically distributed on both sides of the upper end of the tunnel pavement body 3. A second groove 9 is provided through the lower end of the first groove 8. A filter screen 7 and a filter box 6 are installed from top to bottom in the second groove 9. A first ramp 11 is fixed to the end of the first groove 8 near the fifth groove 14. The left and right sides of the fifth groove 14... A fourth trough 12 is opened through both ends. A second slope 13 is fixed to the lower inner wall of the fourth trough 12. An asphalt pavement 15, a buffer layer 16, an infiltration layer 17 and a waterproof adhesive layer 18 are installed in the fifth trough 14 from top to bottom. A bottom storage hopper 4 is fixed to the lower end of the tunnel pavement body 3. A water pump 21 is installed in the bottom storage hopper 4. One end of a connecting pipe 20 is fixed to the right end of the water pump 21. The other end of the connecting pipe 20 passes through the right end of the bottom storage hopper 4 and is fixed to a water tank 2. A bridge tunnel body 1 is fixed to the outer wall of the tunnel pavement body 3. The water tank 2 is located at the right end of the bridge tunnel body 1.

[0027] By using the fourth trough 12 and the second slope 13 in conjunction with the second trough 9 and the first slope 11, some of the rainwater that has infiltrated into the buffer layer 16 and the infiltration layer 17, as well as another part of the rainwater on the tunnel road surface 3, can be guided into the bottom storage hopper 4 for efficient internal and external drainage. This prevents rainwater from accumulating on the tunnel road surface 3 and seeping downwards. The filter screen 7 and the filter box 6 can filter the rainwater flowing into the bottom storage hopper 4 along the first slope 11 and the second slope 13 to prevent debris from clogging the second trough 9 and affecting the normal drainage of rainwater. Furthermore, the water pump 21 can collect the rainwater stored in the bottom storage hopper 4 into the water storage tank 2 for recycling.

[0028] Please see Figures 3-6In this embodiment, the fourth tank 12 is interconnected with the second tank 9, and the second tank 9 is interconnected with the bottom storage hopper 4. During use, the interconnected second tank 9 and bottom storage hopper 4 allow some rainwater that has infiltrated into the buffer layer 16 and the infiltration layer 17, as well as some rainwater on the tunnel pavement body 3, to flow into the bottom storage hopper 4 for storage. The upper end of the slope of the second ramp 13 is on the same plane as the upper end of the waterproof adhesive layer 18, and the upper end of the slope of the first ramp 11 is on the same plane as the upper end of the tunnel pavement body 3. During use, the second ramp 13, which is on the same plane, and the waterproof adhesive layer 18 and the first ramp 11 are on the same plane. The asphalt pavement 15 and the tunnel pavement body 3 are connected in a sloping manner so that the rainwater blocked by the waterproof adhesive layer 18 and the rainwater on the tunnel pavement body 3 can flow into the second trough 9 quickly, thereby improving the drainage efficiency of the rainwater flowing into the bottom storage hopper 4. The upper end of the asphalt pavement 15 and the upper end of the tunnel pavement body 3 are on the same plane, and the lower end of the waterproof adhesive layer 18 and the upper end of the tunnel pavement body 3 are on the same plane. In use, the waterproof adhesive layer 18 and the tunnel pavement body 3, which are on the same plane, can prevent some of the rainwater on the tunnel pavement body 3 from seeping into the soil at the bottom of the tunnel pavement body 3, thereby preventing the tunnel pavement body 3 from sinking.

[0029] Please see Figures 5-6 In this embodiment, a handle 19 symmetrically distributed front and back is fixed to the upper edge of the filter box 6, and a third groove 10 symmetrically distributed front and back is provided at the lower edge of the second groove 9. In use, the handle 19 can facilitate the user to remove the filter box 6 from the second groove 9 for cleaning and maintenance. The handle 19 is set in the third groove 10, the filter screen 7 is located on the upper inner wall of the second groove 9, and the lower end of the filter box 6 is on the same plane as the bottom end of the inclined surface of the second slope 13. In use, the third groove 10 can limit the handle 19 so that the filter box 6 is suspended on the inner wall of the second groove 9.

[0030] Please see Figures 3-5 In this embodiment, the upper end of the tunnel road surface body 3 is fixed with symmetrically distributed railings 5. Two sets of first grooves 8 are located on the left and right sides of the fifth groove 14. The railings 5 ​​are located between the two sets of first grooves 8 and the fifth groove 14. In use, the railings 5 ​​can separate the tunnel road surface body 3 and the filter screen 7 to prevent the car tires from running over the first slope 11 and affecting its driving safety.

[0031] When rainwater flows into the main body 1 of the bridge tunnel, some of the rainwater on the main body 3 of the tunnel road surface will seep down along the asphalt road surface 15 into the buffer layer 16 and the infiltration layer 17, and be blocked by the waterproof adhesive layer 18. The rainwater that seeps into the buffer layer 16 and the infiltration layer 17 will flow down along the surface of the second slope 13 in the fourth trough into the second trough 9, and continue to flow down into the bottom storage hopper 4 for storage.

[0032] Next, another part of the rainwater on the main body of the tunnel surface 3 will flow efficiently into the first trough 8 along the first slope 11, and flow along the inner wall of the first trough 8 through the filter screen 7 and the filter box 6 into the second trough 9. The filter screen 7 and the filter box 6 will then filter the other part of the rainwater to prevent the rainwater from carrying debris and clogging the second trough 9, thus affecting the efficiency of the rainwater flowing down the second trough 9 to the bottom storage hopper 4.

[0033] Then, the water stored in the bottom storage hopper 4 is transported to the water storage tank 2 by the water pump 21 and the connecting pipe 20, so as to meet the needs of subsequent secondary use of rainwater.

[0034] Through the above steps, the fourth trough 12 and the second slope 13, together with the second trough 9 and the first slope 11, can guide some of the rainwater that has infiltrated into the buffer layer 16 and the infiltration layer 17, and another part of the rainwater on the tunnel road surface 3, into the bottom storage hopper 4 for efficient internal and external drainage. This avoids rainwater accumulating on the tunnel road surface 3 and seeping downwards, thus solving the problem that existing bridge tunnels have difficulty in quickly draining rainwater during rainy weather and that rainwater easily accumulates on the road surface, leading to rainwater infiltration.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
