Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a waste leachate collection pond anti-seepage method and structure. BACKGROUND

[0002] Waste is mainly composed of various garbage, and the liquid inside the waste will penetrate to the bottom when it is accumulated. By brushing a waterproof layer in the leachate pond, a certain degree of anti-seepage effect is achieved, which prevents harmful substances in the waste from penetrating into the surrounding soil and water, and achieves the effect of collecting and preventing waste leachate.

[0003] However, the anti-seepage requirement of the garbage bin and the leachate pond is high. When brushing the waterproof layer on the pond wall, the waterproof layer is in a fluid state, which is easy to cause flow collapse when brushing on the vertical pond wall, so that the waterproof layer coating is accumulated at the bottom, and the upper part is not easy to stay due to flow collapse, which causes the thickness of the waterproof layer to be inconsistent when brushing, and the thickness of the waterproof layer is difficult to control. The soil on the ground is loose and easy to collapse, which causes the geotextile to be pulled, and the water in the soil penetrates into the concrete layer, thereby affecting the stability of the waterproof coating.

Detailed Implementation

[0028] 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, and a concave seepage-proof mechanism 3 is provided at the lower end of the horizontal plate 1, and the leachate is collected through the seepage-proof mechanism 3.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] The rotating structure 32 is provided with a connecting rod 321, a rotating ring 322, a stress structure 323, a sliding block 324 and a fixed 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 side bearing of the fixed rod 325, the outer end of the fixed rod 325 is provided with a sliding block 324 in a semicircular structure, the connecting rod 321 is in three-stage rotary activity, and drives the stress structure 323 in the inner side of the rotating ring 322 to be clamped with the sliding block 324, the right side of the rotating ring 322 is a hollow structure, and the fixed rod 325 is connected to the outer end of the fixed block 36 through the hollow structure of the rotating ring 322.

[0033] And before the coating is brushed, the fixed block 36 needs to be fixed in the inner side of the concrete wall body 11, and the fixed block 36 is a turned convex structure, as shown in the accompanying drawings. Figure 3 As shown, the right end of the fixed block 36 is made of rubber material, and the upper and lower sides are made of metal material, through the elastic compression of the rubber material, the fixed block 36 is squeezed into the inner side of the concrete wall body 11 under the sliding of the metal material, so that the arranged and distributed connecting plates 33 are fixed along the inner wall of the concrete wall body 11.

[0034] And the function of the splicing strip 35 is to connect adjacent connecting plates 33, and the splicing strip 35 is in an equidistant arrangement and distribution state, and gaps are arranged between the splicing strips 35, as shown in the accompanying drawings. Figure 3 As shown, when the paint is brushed on the left side, the paint enters the right side and contacts the concrete wall body 11 through the gap of the splicing strip 35, and the splicing strip 35 is relatively close to the inner wall of the concrete wall body 11, when the viscosity of the paint is too high, the fluidity is reduced, and it is difficult to pass through the small gap in the coating process, so that the paint forms a certain limit between the concrete wall body 11 and the splicing strip 35, and the paint in this limit is dried and shaped on the outer wall of the concrete wall body 11 within a certain time, and the subsequent paint fills the gap again, and the thickness is stacked through multiple brushing, so that the paint slowly covers the outside of the splicing strip 35 when brushed multiple times, and the gap plate 31 and the connecting plate 33 block the paint to some extent, so that the excess paint flows down from the left side, and the blocked paint is blocked on the upper end of the gap plate 31 and the connecting plate 33 to form a coating.

[0035] In the application, 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 connecting plate 33 drives the rotating ring 322 to rotate, the stress structure 323 is clamped to the slider 324 on the outer side of the fixed rod 325, the fixing of the connecting plate 33 when being inclined is realized, thereby the inclination angle of the connecting plate 33 and the gap plate 31 is adjusted, the distance between the gap plate 31 and the concrete wall 11 is adjusted, thereby the thickness of the coating is adjusted, then the coating is prevented from flowing down along the inner wall of the concrete wall 11 under the block of the connecting plate 33 and the gap plate 31, the thickness of the coating on the inner wall of the concrete wall 11 is consistent at each position, the coating thickness is prevented from being thin at some positions due to the easy flowing of the coating, and the control of the coating thickness is realized.

[0036] Moreover, the gap plate 31 is made of sponge material, the coating flows into the inside of the gap plate 31, and the coating in the inside of the gap plate 31 is connected after the coating forms a coating under the block of the connecting plate 33 and the gap plate 31, thereby a whole coating is formed.

[0037] Moreover, when the coating is brushed on the inner wall of the concrete wall 11 at the right side of the splicing strip 35, at this time, the elastic strip 34 is in the extrusion state, under the condition that the inclination angle of the connecting plate 33 is unchanged, the elastic strip 34 abutting against the inner wall of the concrete wall 11 will not be deformed again, thereby the coating at the position close to the inner wall of the concrete wall 11 of the splicing strip 35 will not be damaged by the deformation of the elastic strip 34.

[0038] Among them, the stress structure 323 is provided with an arc plate 41, a clamping groove 42 and a rubber strip 43, the rubber strip 43 is attached to the outer side of the arc plate 41, the clamping groove 42 is provided with three, and the clamping groove 42 corresponding to the arc of the fixed rod 325 is distributed on the arc plate 41, the arc plate 41 is fixed at the inner side of the rotating ring 322 at both ends, when the slider 324 slides on the surface of the arc plate 41, the slider 324 elastically bends the arc plate 41 and compresses the rubber strip 43.

[0039] In the application, when the connecting rod 321 drives the rotating ring 322 to rotate, the opposite slider 324 of the rotating ring 322 slides on the surface of the arc plate 41 and clamps to the position of the clamping groove 42, under the elastic force of the rubber strip 43, the slider 324 is clamped to the position of the clamping groove 42, and the rotating force of the rotating ring 322 needs to be greater than the elastic extrusion force of the slider 324 to the clamping groove 42, so that the slider 324 elastically extrudes the arc plate 41 and compresses the rubber strip 43 at the same time, and then through the different clamping angles of the slider 324 at the three clamping groove 42 positions, the effect of adjusting the inclination angle of the connecting rod 321 is realized, thereby the inclination state of the connecting plate 33 outside the connecting rod 321 is adjusted, and the block width of the connecting plate 33 to the coating is adjusted according to the required thickness.

[0040] The base structure 14 is provided with a concrete layer 21, an insulation layer 22, a geotextile 23 and a protruding strip 24, the concrete layer 21 and the insulation layer 22 are arranged in a concave stack, and the opposite sides of the concrete layer 21 and the insulation layer 22 are respectively provided with staggered protruding strips 24, and the staggered protruding strips 24 are provided with a continuously curved geotextile 23.

[0041] The anti-seepage method of the waste leachate collection tank is based on the anti-seepage structure of the waste leachate collection tank, and the specific anti-seepage method is as follows:

[0042] S1: Laying of the collection tank: The inner wall and the bottom of the preset collection tank are laid with an insulation layer 22, and the protruding strips 24 are uniformly arranged on the surface of the insulation 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 two layers of protruding strips 24, and then the relatively rough concrete layer 21 is poured on the uppermost protruding strip 24;

[0043] S2: The relatively fine concrete wall body 11 and the guide plate 12 are painted on the concrete layer 21, and the holes arranged and distributed on the inner side of the concrete wall body 11 and the surface of the guide plate 12 are reserved, so that the blocking mechanism 13 is fixed in the holes, and then the waterproof coating is brushed on the surface of the blocking mechanism 13;

[0044] S3: When the coating is brushed on the blocking mechanism 13, the inclination angle of the gap plate 31 is adjusted according to the required brushing thickness, then the gap plate 31 is manually pressed at the outer end, so that the connecting rod 321 drives the stress structure 323 on the inner side of the rotating ring 322 to be engaged with the sliding block 324, when the sliding block 324 is engaged at the position of the stress structure 323, the rotating angle of the rotating ring 322 is 30°, 45° and 60° respectively, and the rotation of the rotating structure 32 will make the connecting plate 33 and the gap plate 31 rotate in an arc shape, and the distance from the left gap plate 31 to the inner wall of the concrete wall body 11 is extended;

[0045] S4: At this time, the coating is brushed on the upper end of the connecting plate 33 and is attached to the inner wall of the concrete wall body 11 through the splicing strip 35, and the coating is blocked by the connecting plate 33 and the gap plate 31, so that the coating is covered according to the distance from the gap plate 31 to the inner wall of the concrete wall body 11.

[0046] In addition, the leachate in the garbage above the horizontal plate 1 falls to the lower side through the filtration of the permeable plate 2, and is guided to slide to both sides by the inclined guide plate 12, so that the leachate is more concentrated, which is convenient for subsequent discharge or extraction of the leachate.

[0047] In the application, the protruding strips 24 staggeringly fix the upper and lower sides of the geotextile 23, so that the geotextile 23 is in a continuous bending state and is isolated below the concrete layer 21. When the isolation layer 22 collapses at some positions due to low quality and looseness, the geotextile 23 around the collapsed position is still fixed by the protruding strips 24, so that the geotextile 23 is not pulled due to the collapse of the part, and the geotextile 23 is not separated in the base structure 14. The geotextile 23 in the base structure 14 can isolate the influence of the water below on the concrete layer 21, and prevent the concrete layer 21 from being easily penetrated under the influence of water. In addition, the geotextile 23 can also isolate the leakage of the leachate above.

[0048] The above merely describes the preferred embodiments of the present application, and therefore cannot limit the scope of the present application. Any equivalent changes and modifications made according to the scope of the present application and the content of the specification should still be within the scope of the present application.
