Description

Technical Field

[0001] This invention relates to the field of landfill technology, and in particular to a typhoon-resistant system and typhoon-resistant covering method for fly ash landfills. Background Technology

[0002] With the continuous improvement of people's living standards, a large amount of domestic waste is generated every day. There are various existing waste treatment methods, but the most common is still waste incineration. After incineration, the fly ash and leachate need to be landfilled. After landfilling, HDPE membranes need to be welded to the landfill to prevent rainwater from seeping into the landfill area and mixing with the solidified fly ash and leachate, causing larger-scale pollution. However, in existing technologies, the HDPE membranes in landfills do not use briquettes, making them susceptible to damage during typhoons or other extreme weather events. Some landfills do use briquettes to protect the HDPE membranes. PE compaction is effective, but during typhoons, strong winds can blow the compaction blocks away, increasing the risk of large-scale damage to the HDPE membrane. Furthermore, using heavy compaction blocks presents several drawbacks: First, the large area of ​​landfills necessitates a large number of blocks, significantly increasing costs. Second, when the HDPE membrane is blown away by the wind, it can rub against the edges of the compaction blocks, easily causing damage. Third, current compaction techniques typically place the blocks directly on the HDPE membrane without any connection between them, resulting in poor overall compaction. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a typhoon-resistant system and typhoon-resistant covering method for fly ash landfills that can reduce usage costs, improve the compaction effect of HDPE membranes, and extend the service life of HDPE membranes during typhoon weather.

[0004] The technical solution of this invention: A typhoon-resistant system for fly ash landfills, comprising a landfill foundation, an HDPE membrane connected to the landfill foundation, a concrete slab strip fixedly connected to the landfill foundation, a first annular buckle connected to the concrete slab strip, a first connecting element connected to the first annular buckle, a clamping component connected to the first connecting element, and a second connecting element connected to the clamping component. The edge of the HDPE membrane is welded to the concrete slab strip. The clamping component has a plurality of mounting threaded holes, the number of which is greater than or equal to four. The mounting threaded holes are evenly distributed around the central axis of the clamping component. The first connecting element includes a first fixing bolt, a first connecting rope connected to the first fixing bolt, and a hook component connected to the first connecting rope. The second connecting element includes a second fixing bolt, a second connecting rope connected to the second fixing bolt, and a second ring buckle fixedly connected to the second connecting rope. The number of the first connecting element and the second connecting element connected to the pressure block component is the same and is greater than or equal to 2. The positions of the first connecting element and the second connecting element are symmetrical. The hook component can be connected to the first ring buckle or the second ring buckle respectively. The mounting threaded hole is adapted to the shape and size of the first fixing bolt and the second fixing bolt respectively.

[0005] Using the above technical solution, after the landfill work is completed, the compaction components are first evenly distributed on the HDPE membrane. Then, the first connecting element on the compaction component closest to the concrete slab is connected to the first ring buckle on the concrete slab. At the same time, the first connecting element on the compaction component is connected to the second connecting element on the adjacent compaction component, so that the concrete slab and the compaction components are connected into a whole, which greatly improves the compaction effect of the compaction components on the HDPE membrane. At the same time, it can also prevent the compaction components from being blown away in the event of a typhoon, thus improving the typhoon resistance of the compaction components.

[0006] A further feature of the present invention is that the pressing block component is annular, the mounting threaded holes are located on the outer wall of the pressing block component, and the contact end between the pressing block component and the HDPE film is provided with rounded corners.

[0007] By adopting the above technical solution, since the pressing block component is ring-shaped, the volume and weight of the pressing block component are greatly reduced, thereby reducing the cost of use. In addition, since the contact end between the pressing block component and the HDPE film is rounded, damage can be avoided when the HDPE film rubs against the edge of the pressing block component.

[0008] A further feature of the present invention is that a rubber pad is provided at the rounded corner of the pressing block component, and the rubber pad is adapted to the shape and size of the rounded corner on the pressing block component.

[0009] By adopting the above technical solution, since the rounded corners of the pressing block component are provided with rubber pads, and the shape and size of the rubber pads are adapted to the rounded corners on the pressing block component, damage can be further avoided when the HDPE film rubs against the edge of the pressing block component. At the same time, the tightness of the connection between the pressing block component and the HDPE film can be increased.

[0010] A further feature of the present invention is that the bottom of the pressing block component is made of rubber, and the pressing block component has a hollow groove and a vent hole inside. The vent hole communicates with the hollow groove. The hollow groove is provided with a top rod connected to the hollow groove, a spring component connected to the top rod, an inflatable airbag connected to the inner wall of the hollow groove, and a connecting pipe connected to the inflatable airbag. Each pressing block component has two top rods and two inflatable airbags. The positions of the two top rods and the inflatable airbags are symmetrically arranged. The axial direction of the top rod is vertical. The top rod is provided with a pressure groove, and the pressure groove corresponds to the position of the inflatable airbag. An air pump and a controller connected to the air pump are provided on the connecting pipe near the end of the concrete slab.

[0011] Using the above technical solution, the air pump is controlled by the controller to provide air pressure, which increases the volume of the airbag. Since the top rod is equipped with a pressure groove, and the pressure groove corresponds to the position of the airbag, the airbag will press the top rod downward. Since the bottom of the pressure block component is made of rubber, the top rod will further press the bottom of the pressure block against the HDPE film, thereby improving the overall pressing degree of the pressure block component on the HDPE film.

[0012] A further feature of the present invention is that a pressure sensor is also provided on the connecting pipe near one end of the concrete slab.

[0013] With the above technical solution, since a pressure sensor is also installed on the connecting pipe near the concrete slab, the user can determine whether the airbag is inflated to a sufficient volume based on the actual air pressure value of the pressure sensor, thereby ensuring that the pressure of the airbag on the top rod is large enough, and thus ensuring the tightness of the pressing block component on the HDPE film as a whole.

[0014] A method for typhoon-resistant covering of fly ash landfills includes: S1, welding HDPE membranes together using a double-rail welding machine; S2, welding the corners of the HDPE membranes together using a single-rail welding machine; S3, welding the edges of the spliced ​​HDPE membranes to a concrete slab strip; S4, placing the compaction block components on top of the HDPE membranes using a cross-anchoring method, then connecting the first connecting element on the compaction block component closest to the concrete slab strip to the first annular buckle on the concrete slab strip, and simultaneously connecting the first connecting element on the compaction block component to the second connecting element on the adjacent compaction block component.

[0015] By adopting the above technical solution, the HDPE membranes are welded together using a combination of double-rail welding and single-rail welding methods. This ensures that the joints between the HDPE membranes are tight, preventing rainwater from entering through the joints. Then, the cross-anchoring method is used to connect the briquetting components to the concrete slab, thereby further improving the compression effect of the briquetting components on the HDPE membrane and enhancing the system's ability to withstand typhoons.

[0016] A further feature of the present invention is that the distance between the pressing block components is the same as the sum of the lengths of the first connecting element and the second connecting element, and the spacing between the pressing block components is 2 meters.

[0017] By adopting the above technical solution, since the distance between the pressing block components is the same as the sum of the lengths of the first connecting element and the second connecting element, and the spacing between the pressing block components is 2 meters, it can be ensured that the first connecting rope and the second connecting rope are in a taut state, and that the distance between the pressing block components is not too far, thereby further improving the pressing effect of the pressing block components on the HDPE film.

[0018] A further setting of the present invention: S5, the controller controls the air pump to inflate the airbag through the connecting pipe, and at the same time observes the air pressure value transmitted by the air pressure sensor to confirm that the air pressure has reached the threshold.

[0019] By adopting the above technical solution, users can determine whether the airbag is inflated to a sufficient volume based on the actual air pressure value of the air pressure sensor, thereby ensuring that the pressure of the airbag on the top rod is large enough, and thus ensuring the tightness of the pressure block component on the HDPE film as a whole.

Detailed Implementation

[0023] like Figure 1-2 As shown, a typhoon-resistant system for a fly ash landfill includes a landfill foundation 1, an HDPE membrane 2 connected to the landfill foundation 1, a concrete slab strip 3 fixedly connected to the landfill foundation 1, a first annular buckle 4 connected to the concrete slab strip 3, a first connecting element 5 connected to the first annular buckle 4, a pressing block component 6 connected to the first connecting element 5, and a second connecting element 7 connected to the pressing block component 6. The edge of the HDPE membrane 2 is welded to the concrete slab strip 3. The pressing block component 6 has a plurality of mounting threaded holes 8, the number of which is greater than or equal to four. The mounting threaded holes 8 are evenly distributed around the central axis of the pressing block component 6. The first connecting element 5 includes... The first fixing bolt 9, the first connecting rope 10 connected to the first fixing bolt 9, and the hook component 11 connected to the first connecting rope 10; the second connecting element 7 includes a second fixing bolt 12, a second connecting rope 13 connected to the second fixing bolt 12, and a second ring buckle 14 fixedly connected to the second connecting rope 13; the number of the first connecting elements 5 and the second connecting elements 7 connected to the pressure block component 6 are the same and both are greater than or equal to 2; the positions of the first connecting elements 5 and the second connecting elements 7 are symmetrical; the hook component 11 can be connected to the first ring buckle 4 or the second ring buckle 14 respectively; the mounting threaded hole 8 is adapted to the shape and size of the first fixing bolt 9 and the second fixing bolt 12 respectively.

[0024] After the landfilling work is completed, the compaction components 6 are first evenly distributed on the HDPE membrane 2. Then, the first connecting element 5 on the compaction component 6 closest to the concrete slab 3 is connected to the first ring buckle 4 on the concrete slab 3. At the same time, the first connecting element 5 on the compaction component 6 is connected to the second connecting element 7 on the adjacent compaction component 6, so that the concrete slab 3 and the compaction component 6 are connected into a whole, which greatly improves the compaction effect of the compaction component 6 on the HDPE membrane 2. At the same time, it can also prevent the compaction component 6 from being blown away in the event of a typhoon, thus improving the typhoon resistance of the compaction component 6.

[0025] The pressing block component 6 is annular, and the mounting threaded holes 8 are located on the outer wall of the pressing block component 6. The contact end between the pressing block component 6 and the HDPE film 2 is provided with rounded corners.

[0026] Since the pressing component 6 is ring-shaped, its volume and weight are greatly reduced, thereby reducing the cost of use. In addition, since the contact end between the pressing component 6 and the HDPE film 2 is rounded, damage can be avoided when the HDPE film 2 rubs against the edge of the pressing component 6.

[0027] The rounded corner of the pressing block component 6 is provided with a rubber pad 15, and the rubber pad 15 is adapted to the shape and size of the rounded corner on the pressing block component 6.

[0028] Because the rounded corner of the pressing block component 6 is provided with a rubber pad 15, and the shape and size of the rubber pad 15 are adapted to the rounded corner of the pressing block component 6, it can further prevent the HDPE film 2 from being damaged when it rubs against the edge of the pressing block component 6. At the same time, it can increase the tightness of the connection between the pressing block component 6 and the HDPE film 2.

[0029] The bottom of the pressing block component 6 is made of rubber. The pressing block component 6 has a hollow groove 16 and a vent hole 17 inside. The vent hole 17 communicates with the hollow groove 16. The hollow groove 16 has a top rod 18 connected to the hollow groove 16, a spring component 19 connected to the top rod 18, an inflatable airbag 20 connected to the inner wall of the hollow groove 16, and a connecting pipe 21 connected to the inflatable airbag 20. Each pressing block component 6 has two top rods 18 and two inflatable airbags 20. The positions of the two top rods 18 and the inflatable airbags 20 are symmetrically arranged. The axial direction of the top rod 18 is vertical. The top rod 18 has a pressure groove 22. The pressure groove 22 corresponds to the position of the inflatable airbag 20. The connecting pipe 21 near one end of the concrete slab strip 3 is equipped with an air pump 23 and a controller 24 connected to the air pump 23.

[0030] The controller 24 controls the air pump 23 to provide air pressure, which increases the volume of the airbag 20. Since the top rod 18 is provided with a pressure groove 22 and the pressure groove 22 corresponds to the position of the airbag 20, the airbag 20 will press the top rod 18 downward. Since the bottom of the pressure block component 6 is made of rubber, the top rod 18 will further press the bottom of the pressure block and the HDPE film 2 together, thereby improving the overall pressing degree of the pressure block component 6 on the HDPE film 2.

[0031] A pressure sensor 25 is also installed on the connecting pipe 21 near one end of the concrete slab strip 3.

[0032] Since a pressure sensor 25 is also provided on the connecting pipe 21 near one end of the concrete slab strip 3, the user can determine whether the airbag 20 is inflated to a sufficient volume based on the actual air pressure value of the pressure sensor 25, thereby ensuring that the pressure of the airbag 20 on the top rod 18 is large enough, and thus ensuring the overall tightness of the pressure block component 6 on the HDPE film 2.

[0033] A method for typhoon-resistant covering of fly ash landfills includes the following steps: S1, welding HDPE membrane 2 to HDPE membrane 2 using a double-rail welding machine; S2, welding the corners of the HDPE membrane 2 joints using a single-rail welding machine; S3, welding the edges of the joined HDPE membrane 2 to a concrete slab strip 3; S4, placing a pressure block component 6 on top of the HDPE membrane 2 using a cross-anchoring method, then connecting the first connecting element 5 on the pressure block component 6 closest to the concrete slab strip 3 to the first annular buckle 4 on the concrete slab strip 3, and simultaneously connecting the first connecting element 5 on the pressure block component 6 to the second connecting element 7 on the adjacent pressure block component 6.

[0034] By combining double-rail welding and single-rail welding methods, the HDPE membranes 2 are welded together, ensuring a tight joint between them and preventing rainwater from entering through the joints. Then, the cross-anchoring method connects the pressure block component 6 to the concrete slab strip 3 into a whole, thereby further improving the compression effect of the pressure block component 6 on the HDPE membranes 2 and enhancing the system's ability to withstand typhoons.

[0035] The distance between the pressing block component 6 and the pressing block component 6 is the same as the sum of the lengths of the first connecting element 5 and the second connecting element 7, and the spacing between the pressing block component 6 and the pressing block component 6 is 2 meters.

[0036] Since the distance between the pressing block components 6 and 6 is the same as the sum of the lengths of the first connecting element 5 and the second connecting element 7, and the spacing between the pressing block components 6 and 6 is 2 meters, it can be ensured that the first connecting rope 10 and the second connecting rope 13 are in a taut state, and that the distance between the pressing block components 6 and 6 is not too far, thereby further improving the pressing effect of the pressing block components 6 on the HDPE film 2.

[0037] S5, the controller 24 controls the air pump 23 to inflate the airbag 20 through the connecting pipe 21, and at the same time observes the air pressure value transmitted by the air pressure sensor 25 to confirm that the air pressure has reached the threshold.

[0038] Users can determine whether the airbag 20 is inflated to a sufficient volume based on the air pressure value displayed by the air pressure sensor 25, thereby ensuring that the airbag 20 exerts sufficient pressure on the top rod 18, and thus ensuring the overall tightness of the pressure block component 6 on the HDPE film 2.
