Description

Technical Field

[0001] The present invention relates to the technical field of slope protection, in particular to a slope surface water infiltration prevention structure and an anti-seepage method. Background Art

[0002] An engineering slope refers to a slope surface with a certain slope formed by excavation, filling, reinforcement and other treatments of rock and soil to ensure the safety of engineering construction and operation, while a slope anti-seepage structure refers to certain measures taken on the slope to prevent rainwater from seeping into the slope, thereby achieving the purpose of protecting the slope.

[0003] In order to improve the stability of the slope, the existing technology has made many improvements to the slope anti-seepage structure. For example, the patent with patent publication number CN219343253U discloses a slope anti-seepage structure, whose technical solution is: it includes a pre-buried culvert, a plurality of drainage channels are opened on the top of the pre-buried culvert, a permeable steel frame is embedded on the top of the pre-buried culvert, a filter layer is provided on the top of the permeable steel frame, a slope is provided on the top of the filter layer, and a plurality of drainage components are provided inside the slope. The drainage component includes a drainage channel, a filter plate is embedded on the top of the drainage channel, a sleeve is provided at the bottom of the drainage channel, the drainage channel and the sleeve are connected by threads, and a fixing plate is fixed on both sides of the sleeve, and the other side of the fixing plate is fixedly connected to the side wall of the drainage channel. The beneficial effect of this utility model is: the base soil of the vegetation is fixed by using the fixed frame, which can prevent excessive rainfall from generating a huge impact force on the base soil of the vegetation, resulting in a large loss of nutrients in the base soil of the vegetation, affecting the subsequent planting effect, ensuring the stability of the groundwater level, and the accumulated water can be quickly drained away to prevent the groundwater level from changing and avoid collapse.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative documents, the base soil of the vegetation is fixed by a fixed frame to prevent the rapid surface water from carrying away the base soil. However, in reality, part of the surface water will flow along the surface of the slope, and part will penetrate into the interior of the slope, thereby causing the slope foundation to become loose. Long-term water seepage will cause large-scale landslides on the slope. Therefore, this field is in urgent need of a slope surface water anti-infiltration structure and anti-seepage method to solve the defects of the existing technology. Summary of the Invention

[0023] In view of the shortcomings of the prior art, the present invention provides a slope surface water anti-seepage structure and anti-seepage method, which overcomes the shortcomings of the prior art. The beneficial effects of the present invention are:

[0024] In the present invention, when surface water flows over the slope, part of the surface water is discharged into the drainage unit at the bottom through the drainage ditch, and the other part of the surface water is absorbed by the vegetation and the planting soil layer. When the vegetation and the planting soil layer are unable to absorb the surface water, the excess surface water penetrates into the drainage ditch through the seepage unit and is discharged. In addition, due to the obstruction of the waterproof concrete layer, the surface water is prevented from penetrating into the slope body, and the long-term stability of the slope body is maintained in cooperation with the foundation beam.

[0025] In the present invention, when there is a lot of surface water, the surface water flows downward in the drainage ditch. The surface water flowing in the drainage ditch will push the cleaning plate to rotate along the rotation axis. Since the side of the cleaning plate is against the side of the water-permeable membrane, the rotating cleaning plate cleans the water-permeable membrane to prevent the water-permeable membrane from being blocked. The water-permeable membrane can be replaced through the plug-in groove, and the excess surface water can be drained into the drainage ditch, reducing the probability of surface water infiltration.

[0026] In the present invention, by rotating the adjusting bolt, the adjusting bolt drives the sliding block to move upward in the moving cavity, and the sliding block drives the moving frame to move upward. At the same time, the sliding block can move in the moving frame. When the moving frame moves upward, one end of the moving frame is squeezed by the side of the moving cavity, and the moving frame moves toward the card interface position until the adjusting bolt is tightened. At this time, one end of the moving frame is carded in the card interface, and the installation of the drain ditch can be completed, which is convenient for the installer to install it and convenient for the drain ditch to be replaced later.

[0027] In the present invention, the water collecting ditch collects and transports surface water, and the water collecting ditch and the foundation surrounding beam are cast as one body, thereby improving the strength of the water collecting ditch. At the same time, the water collecting ditch has a supporting effect on the slope.

[0028] In the present invention, the supporting piles and grouting anchor rods improve the strength of the overall foundation beam in supporting the slope. After the anchor rods are fixed, the protective mesh, waterproof concrete layer, upper retaining beam, lower retaining beam and foundation beam are cast into a whole, further improving the stability of the overall slope.

[0029] In the present invention, the water flow will be blocked when passing through the second clamping groove position. After passing through each second clamping groove, the potential energy of the water flow is reduced, the impact force of the surface water flow is reduced, and long-term drainage is prevented from damaging the surface of the ditch.

[0030] In the present invention, surface water is filtered by an impurity filter frame, and the impurities in the surface water are pushed to the impurity storage box for storage through a conveying auger, which is convenient for centralized treatment of impurities contained in the surface water. The potential energy of the surface water flow is used to filter the surface water and collect the impurities, thereby reducing the use cost of the entire device and improving the cleanliness of the surface water in the collection ditch.

[0031] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures pointed out in the description, claims and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] See also Figures 1-14 A slope surface water infiltration prevention structure includes a slope body 1, a foundation beam 2 is cast on the slope body 1, a protective mesh 3 is laid and fixed on the upper surface of the foundation beam 2, a waterproof concrete layer 4 is cast on the upper surface of the protective mesh 3, and a plurality of upper retaining beams 5 are cast together with the waterproof concrete layer 4 on the upper surface of the waterproof concrete layer 4. A planting soil layer 7 for planting vegetation is laid between each upper retaining beam 5, and a plurality of drainage ditches 6 are pre-buried on the planting soil layer 7. The opposite side of each drainage ditch 6 is provided with a seepage unit 8 adapted to the upper retaining beam 5. The seepage unit 8 is used to drain rainwater in the planting soil layer 7 into the drainage ditch 6. A quick installation unit 9 is provided between the drainage ditch 6 and the upper retaining beam 5. The drainage ditch 6 is installed and fixed by the quick installation unit 9. A drainage unit 10 is provided at the lower part of the slope body 1, and an impurity collection unit 34 is provided in the drainage unit 10.

[0050] Specifically, the slope body 1 is excavated, and the formwork and steel bars are tied. Then, the foundation beam 2 is poured with concrete. The protective mesh 3 is installed on the upper surface of the foundation beam 2, and the viscous concrete is sprayed on the protective mesh 3. Then, the formwork and steel bars are tied on the protective mesh 3. The waterproof concrete layer 4 and the upper retaining beam 5 are poured. The drainage ditch 6 is installed on several upper retaining beams 5 through the quick installation unit 9. The planting soil layer 7 is filled between the upper retaining beams 5, and vegetation is planted on the planting soil layer 7. When there is a When surface water flows through, part of the surface water is discharged into the lower drainage unit 10 through the drainage ditch 6, and the other part of the surface water is absorbed by the vegetation and planting soil layer 7. When the vegetation and planting soil layer 7 cannot absorb the surface water, the excess surface water penetrates into the drainage ditch 6 through the seepage unit 8 and is discharged. Due to the obstruction of the waterproof concrete layer 4, the surface water is prevented from penetrating into the slope body 1, and the long-term stability of the slope body 1 is maintained in cooperation with the foundation beam 2. The impurity collection unit 34 is used to collect impurities flowing in the drainage ditch 6, which is convenient for centralized treatment of impurities in the later stage.

[0051] As a technical optimization solution of the present invention, the seepage unit 8 includes a plurality of seepage membranes 11 arranged on opposite sides of the drainage ditch 6, and seepage ports 12 are provided through the opposite sides of the drainage ditch 6. A plug-in groove 13 adapted to the seepage membrane 11 is provided on the upper part of the drainage ditch 6, and a rotating shaft 14 is rotatably connected to the seepage port 12 on the opposite side of the drainage ditch 6. The outer wall of the rotating shaft 14 is fixedly connected to a plurality of cleaning plates 15, and one side of the cleaning plate 15 is against the side of the seepage membrane 11.

[0052] Specifically, the seepage port 12 is located on the upper side of each upper retaining beam 5. When the surface water between the two upper retaining beams 5 flows down to the seepage port 12, the excess surface water seeps into the drainage ditch 6. The seepage membrane 11 can adopt a one-way permeable membrane. When there is a lot of surface water, the surface water flows downward in the drainage ditch 6. The surface water flowing in the drainage ditch 6 will push the cleaning plate 15 to rotate along the rotating shaft 14. Since the side of the cleaning plate 15 is against the side of the seepage membrane 11, the rotating cleaning plate 15 will clean the seepage membrane 11 to prevent the seepage membrane 11 from being blocked, and the seepage membrane 11 can be replaced through the plug-in slot 13. The excess surface water can be drained into the drainage ditch 6, reducing the probability of surface water seepage.

[0053] As a technical optimization solution of the present invention, the quick installation unit 9 includes a plurality of adjusting bolts 16 provided on both sides of the upper part of the drainage ditch 6, and stepped holes 17 adapted to the adjusting bolts 16 are provided on both sides of the upper part of the drainage ditch 6.

A card interface 20 adapted to one end of the moving frame 19 is provided in the upper retaining beam 5. A sliding block 21 is slidably connected to the middle of the moving frame 19. The adjusting bolt 16 passes through the sliding block 21 and is threadedly connected to the sliding block 21. A sealing rubber cover 35 is embedded in the top of the stepped hole 17.

[0054] Specifically, the drainage ditch 6 is manufactured in a prefabricated manner, transported to a designated location, and installed by a quick installation unit 9. No on-site production is required, which facilitates construction. When the drainage ditch 6 needs to be installed, the movable cavity 18 on the side of the drainage ditch 6 is aligned with the card interface 20 on the upper retaining beam 5, the drainage ditch 6 is clamped on the upper retaining beam 5, and the adjusting bolt 16 is rotated. When the adjusting bolt 16 rotates, the sliding block 21 is driven to move upward in the movable cavity 18, and the sliding block 21 drives the movable frame 19 to move upward. At the same time, the sliding block 21 can move in the movable frame 19. When the movable frame 19 moves upward, one end of the movable frame 19 is squeezed by the side of the movable cavity 18, and the movable frame 19 moves toward the position of the card interface 20 until the adjusting bolt 16 is tightened. At this time, one end of the movable frame 19 is carded in the card interface 20, and the installation of the drain ditch 6 is completed, which is convenient for the installer to install it and convenient for the drain ditch 6 to be replaced later. When it needs to be replaced, it is only necessary to rotate the adjusting bolt 16 in the reverse direction to disengage one end of the movable frame 19 from the card interface 20. After the installation of the drain ditch 6 is completed, the sealing rubber cover 35 is covered in the stepped hole 17 to seal the inside of the stepped hole 17.

[0055] As a technical optimization solution of the present invention, the drainage unit 10 includes a water collection ditch 22 provided at the lower part of the slope body 1, the side of the water collection ditch 22 is connected to the foundation beam 2, the opposite side walls of the water collection ditch 22 are provided with a clamping platform 23, a hollow cover plate 24 is installed between the two clamping platforms 23, and an arc-shaped water blocking plate 33 is provided on the upper part of the side of the water collection ditch 22 away from the foundation beam 2. The impurity collection unit 34 includes an impurity filter frame 36 provided in the water collection ditch 22, and an impurity storage box 37 connected to the impurity filter frame 36 is provided on one side of the impurity filter frame 36. A square hole connected to the drainage ditch 6 is provided on the side of the impurity filter frame 36 close to the slope body 1, and an opening is provided on the impurity filter frame 36 above the square hole. A rotating shaft 38 is provided in the impurity filter frame 36, and the end of the rotating shaft 38 is rotatably connected to a support frame 39 fixedly installed on the inner wall of the impurity filter frame 36. The outer wall of the rotating shaft 38 is fixedly connected to the conveying auger 40, and several pushing bars 41 are fixedly connected to the conveying auger 40. The side of the impurity filter frame 36 is rotatably connected to the clamping bar 42. A mounting groove 51 adapted to the clamping bar 42 is provided on one side of the water collecting ditch 22. Both sides of the impurity storage box 37 are fixedly connected to fixing bars 43. The inner wall of the water collecting ditch 22 is provided with a fixing groove 45 adapted to the fixing bar 43. The bottom of the impurity storage box 37 is fixedly connected to two symmetrical support plates 44. The lower side of the impurity filter frame 36 is fixedly connected to a fixing plate 46. Several arc-shaped guide rods 49 are passed through the fixing plate 46. Both ends of the arc-shaped guide rods 49 are fixedly connected to baffles 48. A spring 47 is provided on the side of the arc-shaped guide rod 49. The spring 47 is located between the fixing plate 46 and one of the baffles 48. A water guide plate 50 is fixedly connected to one side of the bottom of the drain ditch 6.

[0056] Specifically, the water collection ditch 22 collects and transports the surface water. The water collection ditch 22 and the foundation beam 2 are cast as one body to improve the strength of the water collection ditch 22. At the same time, the water collection ditch 22 has a supporting effect on the slope 1. The hollow cover plate 24 is installed at the position of the clamping platform 23 to filter the large volume of garbage contained in the surface water. The surface water flows under the hollow cover plate 24. After the hollow cover plate 24 is installed, it is clamped in the installation groove 51 through the clamping strip 42, and then the impurity filter frame 36 is hung on the inner wall of the water collection ditch 22. The arc guide rod 4 The baffle 48 at one end of 9 is tightly attached to the inner wall of the water collection ditch 22, and the impurity filter frame 36 is supported by the spring 47. The impurity storage box 37 is installed in the water collection ditch 22 by inserting the fixing bar 43 into the fixing groove 45, and the fixing plate 46 is supported on the hollow cover 24. When surface water flows down the drainage ditch 6 and the planting soil layer 7, the surface water will flow into the impurity filter frame 36. The surface water in the drainage ditch 6 is concentrated and guided into the impurity filter frame 36 through the water guide plate 50, and the surface water and impurities floating on the water flow into the impurity filter frame 36. When the surface water impacts the push bar 41, the rotating shaft 38 rotates, and the rotating shaft 38 rotates, and the conveying screw 40 is driven to rotate. The outer wall of the conveying screw 40 is against the inner wall of the impurity filter frame 36. When the conveying screw 40 rotates, the impurities floating in the surface water are guided to the impurity storage box 37 for storage. The impurity filter frame 36 and the impurity storage box 37 are provided with a plurality of filter holes. The surface water is discharged into the ditch 22 through the filter holes. Later, the impurity storage box 37 can be taken out and the impurities collected therein can be poured out for centralized treatment. When the surface water impacts the impurity filter frame 36 and the impurity storage box 37, the impurities floating in the surface water are guided to the impurity storage box 37 for storage. When the impurity filter frame 36 is formed, the spring 47 plays an elastic supporting role, reducing the impact force of surface water on the impurity filter frame 36, using the potential energy of the surface water to filter the surface water and collect impurities, reducing the use cost of the entire device and improving the cleanliness of the surface water in the ditch 22; if the slope body 1 is located in a river or other location, the ditch 22 can also be used to block the flowing water from scouring the slope body 1, and the arc-shaped water blocking plate 33 is used to reversely guide the water flow in the river or other location to prevent a large amount of turbulent water from flowing back into the ditch 22.

[0057] As a technical optimization solution of the present invention, a plurality of support piles 25 are provided on the upper part of the slope body 1, and a plurality of grouting anchor rods 26 are provided on the inclined surface of the slope body 1. The support piles 25 and the grouting anchor rods 26 are both connected to the foundation beam 2.

[0058] Specifically, the support piles 25 and the grouting anchor rods 26 improve the strength of the overall foundation beam 2 in supporting the slope body 1. The support piles 25 and the grouting anchor rods 26 are installed using existing well-known technologies and will not be described in detail again.

[0059] As a technical optimization solution of the present invention, a number of fixed anchor rods 28 are pre-embedded on the upper surface of the foundation beam 2. The fixed anchor rods 28 pass through the protective mesh 3 and the waterproof concrete layer 4 and are connected to the upper retaining beam 5 and the planting soil layer 7. The protective mesh 3 and the waterproof concrete layer 4 are both connected to the fixed anchor rods 28. A number of lower retaining beams 27 are integrally cast on the lower surface of the foundation beam 2, and the several lower retaining beams 27 are all connected to the slope body 1.

[0060] Specifically, the fixed anchor rods 28 are pre-buried before pouring the foundation beam 2. After the protective mesh 3, waterproof concrete layer 4, upper retaining beam 5, lower retaining beam 27 and foundation beam 2 are poured, they form a whole, further improving the stability of the overall slope body 1.

[0061] As a technical optimization solution of the present invention, a plurality of first clipping grooves 29 are provided on the upper side surface of each upper retaining beam 5, and a second clipping groove 30 adapted to the first clipping groove 29 is provided on the lower side surface of each drainage ditch 6. The second clipping groove 30 extends toward the inner wall of the drainage ditch 6, forming a plurality of protrusions on the inner lower wall of the drainage ditch 6.

[0062] Specifically, when the drainage ditch 6 is installed, the second clamping groove 30 is clamped in the first clamping groove 29. Since the surface water flowing downstream has a strong impact force, the water flow will be blocked when passing through the second clamping groove 30. After passing through each second clamping groove 30, the potential energy of the water flow is reduced to prevent the faster flow of water from causing damage to the water collection ditch 22 below. The cooperation between the second clamping groove 30 and the first clamping groove 29 improves the stability of the drainage ditch 6 after installation.

[0063] As a technical optimization solution of the present invention, both sides of the sliding block 21 are fixedly connected to the limiting blocks 31, and the opposite side walls of the moving frame 19 are provided with limiting grooves 32 adapted to the limiting blocks 31.
