Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a method and structure for preventing seepage in a waste leachate collection pool. Background Technology

[0002] The waste is mainly composed of various types of garbage. When the waste is piled up, the liquid inside will seep to the bottom. By applying a waterproof layer to the leachate tank, a certain degree of anti-seepage effect can be achieved, preventing harmful substances in the waste from seeping into the surrounding soil and water bodies, and achieving the anti-seepage effect of collecting leachate from the waste.

[0003] However, landfills and leachate tanks have high requirements for seepage prevention. When applying a waterproof layer to the tank walls, the waterproof layer is in a fluid state and tends to drip when applied to the vertical tank walls. This causes the waterproof layer coating to accumulate at the bottom, while the dripping coating does not easily settle at the top, resulting in inconsistent thickness of the waterproof layer and making it difficult to control the thickness of the waterproof layer. Furthermore, the bottom of the collection tank is built on the ground with concrete. When the soil is loose, it can easily fall and pull on the geotextile. At the same time, moisture in the soil can seep into the concrete layer, thus affecting the stability of the waterproof coating. Summary of the Invention

[0004] This invention provides a seepage prevention method and structure for a waste leachate collection pool, which overcomes the shortcomings described in the background art.

[0005] The technical solution adopted by this invention to solve its technical problem is: A seepage-proof structure for a waste leachate collection pool includes a horizontal plate, a permeable plate, and a seepage-proof mechanism. The permeable plate is horizontally placed at the upper end of the horizontal plate for filtration, and a concave seepage-proof mechanism is provided at the lower end of the horizontal plate to collect leachate. The seepage prevention mechanism includes a concrete wall, a guide plate, a blocking mechanism, and a base structure. The concrete wall is arranged concavely along the base structure. The guide plate is distributed at an incline at the bottom of the concrete wall. The blocking mechanism is attached to the surface of the concrete wall and the guide plate, and the coating is applied to the surface of the concrete wall.

[0006] Furthermore, the blocking mechanism includes a gap plate, a rotating structure, a connecting plate, an elastic strip, a splicing strip, and a fixing block. The gap plate is fixed to the outer end of the rotating structure via the connecting plate. An elastic strip is provided on the side of the connecting plate, and the elastic strip presses against the side of the concrete wall. The fixing block is on the side of the concrete wall, and the rotating structure is fixed at the position corresponding to the fixing block. The splicing strip connects adjacent connecting plates, and the connecting plates are arranged vertically.

[0007] Furthermore, the rotating structure includes a connecting rod, a rotating ring, a force-bearing structure, a slider, and a fixed rod. The connecting rod is connected to the outer end of the rotating ring, and the rotating ring rotates on the outer bearing of the fixed rod. The outer end of the slider is provided with a semi-circular slider structure. The connecting rod rotates in three stages and drives the force-bearing structure on the inner side of the rotating ring to engage with the slider. The middle right side of the rotating ring is a hollow structure, and the right end of the fixed rod passes through the hollow structure of the rotating ring and connects to the outer end of the fixed block.

[0008] Furthermore, the force-bearing structure is provided with an arc-shaped plate, a slot, and a rubber strip. The rubber strip is attached to the outside of the arc-shaped plate. There are three slots, and the slots are distributed on the arc-shaped plate according to the curvature of the fixing rod. The two ends of the arc-shaped plate are fixed to the inside of the rotating ring. When the slider slides on the surface of the arc-shaped plate, the slider elastically bends the arc-shaped plate and compresses the rubber strip.

[0009] Furthermore, the base structure includes a concrete layer, an isolation layer, geotextile, and protruding strips. The concrete layer and the isolation layer are stacked in a concave shape. The concrete layer and the isolation layer are respectively provided with staggered protruding strips on opposite sides. Continuously curved geotextile is provided between the staggered protruding strips.

[0010] A method for preventing seepage in a waste leachate collection pond, based on the aforementioned seepage-proof structure, includes the following steps: S1: Laying of the water collection pool: The inner wall and bottom of the pre-set water collection pool are laid with an isolation layer, and the protruding strips are evenly arranged on the surface of the isolation layer to lay the geotextile in a continuous arc shape. Then, protruding strips are placed on the surface of the geotextile again so that the geotextile is wrapped by the upper and lower layers of protruding strips. Finally, a relatively rough concrete layer is poured on the uppermost protruding strip. S2: Apply a finely textured concrete wall and guide plate to the inside of the concrete layer, and leave holes arranged in a row on the inside of the concrete wall and the surface of the guide plate so that the blocking mechanism is fixed in the holes, thereby applying a waterproof coating to the surface of the blocking mechanism. S3: When the coating is applied to the blocking mechanism, adjust the tilt angle of the gap plate according to the required coating thickness, and then manually press the gap plate at the outer end to make the connecting rod drive the force structure on the inner side of the rotating ring to engage with the slider. When the slider is engaged in the position of the force structure, the rotation angle of the rotating ring is 30°, 45° and 60° respectively. The rotation of the rotating structure will cause the connecting plate and the gap plate to rotate in an arc and extend the distance from the left gap plate to the inner wall of the concrete wall. S4: At this point, the coating is applied to the upper part of the connecting plate and passes through the splicing strip to adhere to the inner wall of the concrete wall. The coating is partially blocked by the connecting plate and the gap plate, so that the coating covers the inner wall of the concrete wall according to the distance from the gap plate.

[0011] Compared with existing technologies, this technical solution has the following advantages: In this invention, the distance between the gap plate and the inner wall of the concrete wall is the thickness of the coating. By manually pressing the gap plate, the connecting rod in the middle of the connecting plate drives the rotating ring to rotate, causing the force-bearing structure to engage with the slider on the outside of the fixing rod, thus fixing the connecting plate when it is tilted. By adjusting the tilt angle of the connecting plate and the gap plate, the distance between the gap plate and the concrete wall can be adjusted, thereby adjusting the coating thickness. Furthermore, the connection plate and the gap plate prevent the coating from flowing down the inner wall of the concrete wall, ensuring that the coating thickness on the inner wall of the concrete wall is consistent at every position. This avoids the coating thickness being too thin in some areas due to the coating easily dripping, thus achieving control over the coating thickness.

[0012] In this invention, protruding strips are used to fix the geotextile on both the upper and lower sides in an alternating manner, keeping the geotextile in a continuously curved state and isolating it from the concrete layer below. Thus, when the insulating layer collapses in some areas due to low quality and looseness, the geotextile around the collapsed area is still fixed by the protruding strips in an alternating manner, thereby avoiding the geotextile being pulled by the partial collapse and preventing the geotextile from detaching from the base structure. This allows the geotextile in the base structure to isolate the impact of moisture on the concrete layer below, preventing the concrete layer from easily seeping into the upper part under the influence of moisture and affecting the stability of the barrier mechanism. At the same time, the geotextile can also prevent leakage of leachate from above. Attached Figure Description

Detailed Implementation

[0021] like Figures 1 to 6 As shown, the present invention proposes a seepage-proof structure for a waste leachate collection pool, including a horizontal plate 1, a permeable plate 2, and a seepage-proof mechanism 3. The permeable plate 2 is placed horizontally on the upper end of the horizontal plate 1 for filtration, and a concave seepage-proof mechanism 3 is provided at the lower end of the horizontal plate 1, through which leachate is collected. The seepage prevention mechanism 3 includes a concrete wall 11, a guide plate 12, a blocking mechanism 13, and a base structure 14. The concrete wall 11 is arranged concavely along the base structure 14. The guide plate 12 is distributed at an incline at the bottom of the concrete wall 11. The blocking mechanism 13 is attached to the surface of the concrete wall 11 and the guide plate 12, and the paint is applied to the surface of the concrete wall 11.

[0022] The blocking mechanism 13 includes a gap plate 31, a rotating structure 32, a connecting plate 33, an elastic strip 34, a splicing strip 35, and a fixing block 36. The gap plate 31 is fixed to the outer end of the rotating structure 32 via the connecting plate 33. The connecting plate 33 has an elastic strip 34 on its side, which presses against the side of the concrete wall 11. The fixing block 36 is on the side of the concrete wall 11, and the rotating structure 32 is fixed at the position corresponding to the fixing block 36. The splicing strip 35 connects adjacent connecting plates 33, and the connecting plates 33 are arranged vertically.

[0023] Furthermore, the concrete wall 11 is made of concrete. Before laying the base structure 14, a pit needs to be pre-set for the construction of the water collection tank. The base structure 14 is set at the bottom along the shape of the pit, and the concave base structure 14 at the bottom extends along the lower surface of the horizontal plate 1 around the perimeter, so that when the leachate flows from the surface of the horizontal plate 1 to the permeation plate 2, it will not seep from the horizontal plate 1 into the soil.

[0024] The rotating structure 32 includes a connecting rod 321, a rotating ring 322, a force-bearing structure 323, a slider 324, and a fixing rod 325. The connecting rod 321 is connected to the outer end of the rotating ring 322, and the rotating ring 322 rotates on the outer bearing of the fixing rod 325. The outer end of the slider 324 is provided with a semi-circular structure. The connecting rod 321 rotates in three stages and drives the force-bearing structure 323 on the inner side of the rotating ring 322 to engage with the slider 324. The middle right side of the rotating ring 322 is a hollow structure, and the right end of the fixing rod 325 passes through the hollow structure of the rotating ring 322 and connects to the outer end of the fixing block 36.

[0025] Furthermore, before applying the coating, the fixing block 36 needs to be fixed to the inside of the concrete wall 11. The fixing block 36 is a flipped convex structure, as shown in the attached figure. Figure 3 As shown, the middle of the right end of the fixing block 36 is made of rubber, and the upper and lower sides are made of metal. Through the elastic compression of the rubber material, the fixing block 36 is squeezed into the inner side of the concrete wall 11 by the sliding of the metal material, thereby fixing the arranged connecting plates 33 along the inner wall of the concrete wall 11.

[0026] Furthermore, the splicing strip 35 serves to connect adjacent connecting plates 33. The splicing strips 35 are arranged at equal intervals, with gaps between them, as shown in the attached diagram. Figure 3 As shown, when the paint is applied on the left side, it passes through the gap of the splicing strip 35 and enters the right side to contact the concrete wall 11. The splicing strip 35 is relatively close to the inner wall of the concrete wall 11. When the viscosity of the paint is too high, its fluidity decreases, and it is difficult to pass through the tiny gaps during the application process. This creates a certain limit between the concrete wall 11 and the splicing strip 35, allowing the paint to dry and set on the outer wall of the concrete wall 11 within this limit time. When the paint is applied again, it fills the gaps, and through multiple applications, the paint gradually covers the outside of the splicing strip 35. The gap plate 31 and the connecting plate 33 provide some obstruction to the paint, allowing excess paint to flow down from the left side. The obstructed paint is blocked at the upper end of the gap plate 31 and the connecting plate 33, thus forming a coating.

[0027] In this invention, the distance between the gap plate 31 and the inner wall of the concrete wall 11 is the thickness of the coating. By manually pressing the gap plate 31, the connecting rod 321 in the middle of the connecting plate 33 drives the rotating ring 322 to rotate, so that the force-bearing structure 323 engages with the slider 324 on the outside of the fixing rod 325, thereby fixing the connecting plate 33 when it is tilted. By adjusting the tilt angle of the connecting plate 33 and the gap plate 31, the distance between the gap plate 31 and the concrete wall 11 can be adjusted, thereby adjusting the thickness of the coating. Furthermore, under the obstruction of the connecting plate 33 and the gap plate 31, the coating is prevented from flowing down the inner wall of the concrete wall 11, so that the coating thickness on the inner wall of the concrete wall 11 is consistent at every position, avoiding the coating thickness being too thin in some places due to the easy dripping of the coating, thus achieving control of the coating thickness.

[0028] Furthermore, since the gap plate 31 is made of sponge material, the paint will flow into the interior of the gap plate 31. After the paint forms a coating under the obstruction of the connecting plate 33 and the gap plate 31, it connects with the paint inside the gap plate 31 to form an integral coating.

[0029] Furthermore, when the paint is applied to the inner wall of the concrete wall 11 on the right side of the splicing strip 35, the elastic strip 34 is under compression. With the inclination angle of the connecting plate 33 remaining unchanged, the elastic strip 34 will not deform again when pressed against the inner wall of the concrete wall 11. Thus, the paint will not be damaged by the deformation of the elastic strip 34 when the splicing strip 35 is close to the inner wall of the concrete wall 11.

[0030] The force-bearing structure 323 includes an arc-shaped plate 41, a slot 42, and a rubber strip 43. The rubber strip 43 is attached to the outer side of the arc-shaped plate 41. There are three slots 42, and the slots 42 are distributed on the arc-shaped plate 41 corresponding to the arc of the fixing rod 325. The two ends of the arc-shaped plate 41 are fixed to the inner side of the rotating ring 322. When the slider 324 slides on the surface of the arc-shaped plate 41, the slider 324 elastically bends the arc-shaped plate 41 and compresses the rubber strip 43.

[0031] In this invention, when the connecting rod 321 drives the rotating ring 322 to rotate, the slider 324 opposite the rotating ring 322 slides on the surface of the arc plate 41 and engages with the slot 42. Under the elastic force of the rubber strip 43, the slider 324 is engaged with the slot 42. The rotational force of the rotating ring 322 needs to be greater than the elastic extrusion force of the slider 324 on the slot 42 so that the slider 324 can elastically extrude the arc plate 41 while compressing the rubber strip 43. Thus, by adjusting the angle of engagement of the slider 324 at the three slots 42, the tilt angle of the connecting rod 321 can be adjusted, thereby adjusting the tilt state of the external connecting plate 33 of the connecting rod 321. The blocking width of the connecting plate 33 on the coating can be adjusted according to the required thickness.

[0032] The base structure 14 includes a concrete layer 21, an isolation layer 22, a geotextile 23, and protruding strips 24. The concrete layer 21 and the isolation layer 22 are stacked in a concave shape. The concrete layer 21 and the isolation layer 22 are respectively provided with staggered protruding strips 24 on opposite sides. The staggered protruding strips 24 are provided with continuously curved geotextile 23 between them.

[0033] A method for preventing seepage in a waste leachate collection pond, based on the aforementioned seepage-proof structure, includes the following steps: S1: Laying of the water collection pool: The inner wall and bottom of the pre-set water collection pool are laid with an isolation layer 22, and the protruding strips 24 are evenly arranged on the surface of the isolation layer 22, so that the geotextile 23 is laid in a continuous arc shape, and the protruding strips 24 are placed on the surface of the geotextile 23 again, so that the geotextile 23 is wrapped by the upper and lower layers of protruding strips 24, and then a relatively rough concrete layer 21 is poured on the uppermost protruding strip 24. S2: A fine concrete wall 11 and guide plate 12 are painted inside the concrete layer 21, and holes are pre-drilled on the inside of the concrete wall 11 and the surface of the guide plate 12, so that the blocking mechanism 13 is fixed in the holes, and a waterproof coating is applied to the surface of the blocking mechanism 13. S3: When the coating is applied to the blocking mechanism 13, the tilt angle of the gap plate 31 is adjusted according to the required coating thickness. Then, the gap plate 31 is manually pressed at the outer end, so that the connecting rod 321 drives the force-bearing structure 323 on the inner side of the rotating ring 322 to engage with the slider 324. When the slider 324 is engaged in the position of the force-bearing structure 323, the rotation angle of the rotating ring 322 is 30°, 45° and 60° respectively. The rotation of the rotating structure 32 will cause the connecting plate 33 and the gap plate 31 to rotate in an arc and extend the distance from the left gap plate 31 to the inner wall of the concrete wall 11. S4: At this time, the coating is applied to the upper end of the connecting plate 33 and passes through the splicing strip 35 to adhere to the inner wall of the concrete wall 11. The coating is blocked to a certain extent by the connecting plate 33 and the gap plate 31, so that the coating covers the inner wall of the concrete wall 11 according to the distance from the gap plate 31 to the inner wall of the concrete wall 11.

[0034] Furthermore, the leachate in the waste above the horizontal plate 1 falls down through the filtration of the permeation plate 2, and is guided to slide to both sides by the inclined guide plate 12, making the leachate more concentrated and facilitating subsequent discharge or extraction of the leachate.

[0035] In this invention, the protruding strips 24 are staggered and fixed to the upper and lower sides of the geotextile 23, so that the geotextile 23 is in a continuously bent state and isolated below the concrete layer 21. Thus, when the isolation layer 22 collapses in part due to low quality and looseness, the geotextile 23 around the collapsed position is still staggered and fixed by the protruding strips 24, thereby avoiding the pulling of the geotextile 23 caused by partial collapse and preventing the geotextile 23 from detaching from the base structure 14. This allows the geotextile 23 in the base structure 14 to isolate the impact of the water below on the concrete layer 21, preventing the concrete layer 21 from easily seeping under the influence of water. At the same time, the geotextile 23 can also isolate the leakage of leachate from above.

[0036] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
