[0002] With the improvement of living standards, the amount of garbage discharged increases year by year. Except for a small amount of garbage being recycled and used as fertilizers, most of the garbage is transported to landfills for landfill. After being affected by the long-term cycle of wind, sun, and rain, the existing landfill capping structures are prone to problems such as micro-cracks and topsoil landslides. At the same time, due to the uneven settlement of the garbage body, the width of the cracks will be aggravated, resulting in problems such as landfill gas leakage.

[0003] In the prior art CN214235529U, a PCA geocell is laid at the bottom of the greening soil layer, which improves the load-bearing performance of the soil layer, effectively solves the problems of topsoil stability and uneven settlement, is simple in construction, has a stable structure, strong anti-seepage performance, and can reduce the infiltration of rainwater into the garbage heap to achieve the purpose of reducing landfill leachate.

[0004] In a landfill, garbage will generate gases such as methane and carbon dioxide. However, in the prior art, the air pressure of the landfill cannot be inspected, and the gas problems in the landfill cannot be detected and handled in time, increasing environmental pollution and potential safety hazards. Content of the Utility Model

[0005] The purpose of the utility model is to provide a landfill covering structure, which solves the problems in the prior art that the air pressure of the landfill cannot be inspected, the gas problems in the landfill cannot be detected and handled in time, increasing environmental pollution and potential safety hazards.

[0006] To achieve the above purpose, the utility model provides a landfill covering structure, which includes an anti-seepage layer, a greening soil layer, and four air pressure detection mechanisms. The air pressure detection mechanism includes a transparent cylinder, a clamping block, a moving block, a first filter plate, a dust-proof component, and a scale. The greening soil layer and the anti-seepage layer have four through holes. The greening soil layer is fixedly connected to the anti-seepage layer and is located above the anti-seepage layer, and the through holes penetrate through the greening soil layer and the anti-seepage layer. The transparent cylinder is fixedly connected to the anti-seepage layer and the greening soil layer and is located in the through hole. The clamping block is fixedly connected to the transparent cylinder and is located below the transparent cylinder. The moving block is slidably connected to the transparent cylinder and is located inside the transparent cylinder. The first filter plate is fixedly connected to the anti-seepage layer and is located on the through hole. The dust-proof component is arranged above the transparent cylinder. The scale is fixedly connected to the transparent cylinder.

[0007] Among them, the dust-proof component includes a second filter plate and a connection kit. The second filter plate is arranged on the connection kit, and the connection kit is detachably connected above the transparent cylinder.

[0008] Among them, the connection kit includes a fixing ring and a fixing cylinder. The fixing cylinder has internal threads, and the transparent cylinder has external threads. Both ends of the fixing ring are fixedly connected to the second filter plate and the fixing cylinder respectively, and the fixing cylinder and the transparent cylinder are threadedly connected through the internal threads and the external threads.

[0009] Among them, the air pressure detection mechanism further includes a fixing frame and a waterproof cover. The fixing frame is fixedly connected to the greening soil layer, and the transparent cylinder is located inside the fixing frame. The waterproof cover is fixedly connected to the fixing frame and is located above the transparent cylinder.

[0010] Among them, the landfill covering structure further includes four sealing mechanisms, and the four sealing mechanisms are respectively arranged on the four transparent cylinders and the greening soil layer.

[0011] Among them, the sealing mechanism includes a mounting ring and a sealing block. The mounting ring is fixedly connected to the greening soil layer, and the transparent cylinder is located inside the mounting ring. The sealing block is detachably connected to the mounting ring.

[0012] A landfill covering structure of the present utility model, wherein the greening soil layer is fixedly connected to the anti-seepage layer and is located above the anti-seepage layer, and the through hole penetrates through the greening soil layer and the anti-seepage layer. The transparent cylinder is fixedly connected to the anti-seepage layer and the greening soil layer and is located within the through hole. The clamping block is fixedly connected to the transparent cylinder and is located below the transparent cylinder. The moving block is slidably connected to the transparent cylinder and is located within the transparent cylinder. The first filter plate is fixedly connected to the anti-seepage layer and is located on the through hole. The dust-proof component is arranged above the transparent cylinder. The scale is fixedly connected to the transparent cylinder. After the anti-seepage layer and the greening soil layer cover the landfill, the gas generated in the landfill will increase the air pressure in the landfill. When the air pressure in the landfill is greater than the normal air pressure of the environment, the moving block will leave the clamping block and move upward to the corresponding position. Since the transparent cylinder is made of a transparent material, the operator can directly observe the position of the moving block within the transparent cylinder, and then record the accurate height of the moving block through the scale, so as to calculate whether the air pressure in the landfill is within the normal range. By observing the moving blocks in other transparent cylinders, when the heights of all the moving blocks in their respective transparent cylinders are the same, it can be judged that the air pressure in the landfill is balanced. When the heights of multiple moving blocks are different, it means that the air pressure in the landfill is unbalanced. The first filter plate isolates the garbage in the landfill from the transparent cylinder, preventing the garbage from entering the transparent cylinder through the through hole and blocking the lower end of the transparent cylinder. The dust-proof component prevents impurities in the surrounding environment from entering the transparent cylinder. This device ensures that gas problems in the landfill can be detected and handled in a timely manner, reducing environmental pollution and potential safety hazards. Brief Description of the Drawings

Detailed implementation manners

[0021] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0022] The first embodiment of this application is:

[0023] Please refer to Figures 1-4 , Figure 1 which is a schematic diagram of the overall structure of the first embodiment of the landfill covering structure of the present utility model, Figure 2 which is a cross-sectional view of the overall structure of the first embodiment of the landfill covering structure of the present utility model, Figure 3 which is a sectional view of the transparent cylinder of the first embodiment of the landfill covering structure of the present utility model, Figure 4 which is a schematic diagram of the structure of the dust-proof component of the first embodiment of the landfill covering structure of the present utility model.

[0024] The present utility model provides a landfill covering structure, including an impermeable layer 101, a greening soil layer 102 and four air pressure detection mechanisms. The air pressure detection mechanism includes a transparent cylinder 103, a clamping block 107, a moving block 108, a first filter plate 110, a dust-proof component, a scale 106, a fixing frame 104 and a waterproof cover 105. The greening soil layer 102 and the impermeable layer 101 have four through holes 109. The dust-proof component includes a second filter plate 113 and a connecting kit. The connecting kit includes a fixing ring 112 and a fixing cylinder 111. The fixing cylinder 111 has an internal thread 115, and the transparent cylinder 103 has an external thread 114. Through the foregoing solution, the problems in the prior art that the air pressure of the landfill cannot be checked, the gas problems in the landfill cannot be discovered and processed in time, and the environmental pollution and potential safety hazards are increased are solved.

[0025] In this specific embodiment, the greening soil layer 102 is fixedly connected to the anti-seepage layer 101 and is located above the anti-seepage layer 101. Moreover, the through hole 109 penetrates through the greening soil layer 102 and the anti-seepage layer 101. The transparent cylinder 103 is fixedly connected to the anti-seepage layer 101 and the greening soil layer 102 and is located within the through hole 109. The clamping block 107 is fixedly connected to the transparent cylinder 103 and is located below the transparent cylinder 103. The moving block 108 is slidably connected to the transparent cylinder 103 and is located within the transparent cylinder 103. The first filter plate 110 is fixedly connected to the anti-seepage layer 101 and is located on the through hole 109. The dust-proof component is arranged above the transparent cylinder 103. The scale 106 is fixedly connected to the transparent cylinder 103. After the anti-seepage layer 101 and the greening soil layer 102 cover the landfill, the gas generated in the landfill will increase the air pressure in the landfill. When the air pressure in the landfill is greater than the normal air pressure of the environment, the moving block 108 will leave the clamping block 107 and move upward to the corresponding position. Since the transparent cylinder 103 is made of a transparent material, the operator can directly observe the position of the moving block 108 within the transparent cylinder 103, and then record the accurate height of the moving block 108 through the scale 106, so as to measure whether the air pressure in the landfill is within the normal range. By observing the moving blocks 108 in other transparent cylinders 103, when the heights of all the moving blocks 108 in their respective transparent cylinders 103 are the same, it can be judged that the air pressure in the landfill is balanced. When the heights of multiple moving blocks 108 are different, it indicates that the air pressure in the landfill is unbalanced. The first filter plate 110 isolates the garbage in the landfill from the transparent cylinder 103, preventing the garbage from entering the transparent cylinder 103 through the through hole 109 and blocking the lower end of the transparent cylinder 103. The dust-proof component prevents impurities in the surrounding environment from entering the transparent cylinder 103. This device ensures that gas problems in the landfill can be discovered and handled in a timely manner, reducing environmental pollution and potential safety hazards.

[0026] Among them, the second filter plate 113 is disposed on the connection kit, the connection kit is detachably connected above the transparent cylinder 103, both ends of the fixing ring 112 are fixedly connected to the second filter plate 113 and the fixing cylinder 111 respectively, the fixing cylinder 111 and the transparent cylinder 103 are threadedly connected through the internal thread 115 and the external thread 114, the fixing frame 104 is fixedly connected to the greening soil layer 102, and the transparent cylinder 103 is located within the fixing frame 104. The waterproof cover 105 is fixedly connected to the fixing frame 104 and is located above the transparent cylinder 103. The second filter plate 113 prevents impurities in the surrounding environment from entering the transparent cylinder 103 and pressing on the moving block 108, resulting in an increase in the weight of the moving block 108, and further causing errors in the test results. The operator regularly disassembles and cleans the second filter plate 113 to ensure that the second filter plate 113 remains unobstructed, so that the air pressure above the transparent cylinder 103 is the same as the external air pressure. The waterproof cover 105 covers the transparent cylinder 103 to ensure that rainwater does not enter the transparent cylinder 103. This device ensures that gas problems in the landfill can be detected and handled in a timely manner, reducing environmental pollution and potential safety hazards.

[0027] When using the present utility model to detect the air pressure in a landfill, after the anti-seepage layer 101 and the greening soil layer 102 cover the landfill, the gas generated in the landfill will increase the air pressure in the landfill. When the air pressure in the landfill is greater than the normal air pressure of the environment, the moving block 108 will leave the clamping block 107 and move upward to the corresponding position. Since the transparent cylinder 103 is made of a transparent material, the operator can directly observe the position of the moving block 108 in the transparent cylinder 103, and then record the accurate height of the moving block 108 through the scale 106 to calculate whether the air pressure in the landfill is within the normal range. By observing the moving blocks 108 in other transparent cylinders 103, when the heights of all the moving blocks 108 in their respective transparent cylinders 103 are the same, it can be determined that the air pressure in the landfill is balanced. When the heights of multiple moving blocks 108 are different, it indicates that the air pressure in the landfill is unbalanced. This device ensures that gas problems in the landfill can be detected and handled in a timely manner, reducing environmental pollution and potential safety hazards.

[0028] The second embodiment of this application is:

[0029] Please refer to Figures 5-6 , Figure 5 which is the overall structural schematic diagram of the second embodiment of the landfill covering structure of the present utility model, Figure 6 is Figure 5An enlarged view of part A. On the basis of the first embodiment, the landfill covering structure of this embodiment further includes four sealing mechanisms, and the four sealing mechanisms are respectively arranged on the four transparent cylinders 103 and the greening soil layer 102. The sealing mechanism includes a mounting ring 201 and a sealing block 202.

[0030] The mounting ring 201 is fixedly connected to the greening soil layer 102, and the transparent cylinder 103 is located inside the mounting ring 201. The sealing block 202 is detachably connected to the mounting ring 201. The sealing block 202 is stuck on the mounting ring 201, and the sealing block 202 seals the gap at the connection between the transparent cylinder 103 and the greening soil layer 102, preventing the gas in the landfill from flowing out through the gap, playing a role in environmental protection, and at the same time increasing the accuracy of the air pressure detection of the landfill.
