Description

Technical Field

[0001] This utility model relates to the field of slope seepage prevention technology, specifically a slope seepage prevention structure for a landfill. Background Technology

[0002] Landfills are centralized waste disposal sites that use sanitary landfilling methods. Sanitary landfills are widely used in China because of their low cost and good sanitation. The slopes of landfills are all equipped with anti-seepage structures to prevent wastewater from seeping into the ground and damaging water resources. Therefore, an anti-seepage structure for landfill slopes is needed.

[0003] Although existing landfill slope seepage prevention structures offer many advantages, they still suffer from the following problems: Traditional seepage prevention structures mostly rely solely on the geomembrane for seepage prevention. However, since the slope is an inclined structure, the waste will move relative to the slope during landfilling, causing the geomembrane to be subjected to tensile deformation, which can damage the geomembrane in severe cases. Secondly, the existing seepage prevention structures are relatively weak and are easily affected by external damage, thus affecting their seepage prevention effect. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] 1. Technical problems to be solved:

[0006] In order to solve the problems mentioned above, such as the geomembrane being deformed under tensile force, which can lead to damage in severe cases, and the existing geomembrane structure being weak and easily affected by external damage, thus affecting the geomembrane's effectiveness, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a slope seepage prevention structure for landfills, aiming to solve the problem of the seepage prevention membrane being deformed by tensile force, which may damage the seepage prevention membrane in severe cases, and to achieve the goal of maintaining a better seepage prevention effect.

[0015] 3. Beneficial effects:

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This type of landfill slope seepage prevention structure uses a motor-driven conveyor belt to drive rollers to slide on the inner wall of the slot, which facilitates sliding connection along the slot on the top of the slope body, i.e. the surface of the seepage prevention membrane.

[0031] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0032] This utility model provides an overall structural schematic diagram of one embodiment of a landfill slope seepage prevention structure, including:

[0033] Please see Figures 1-6 This utility model provides a technical solution:

[0034] A landfill slope seepage prevention structure includes a slope body 1. A slot 8 is formed at the top of the slope body 1, and a locking pin 9 is threaded onto the inner wall of the slot 8. A nut 10 is fixed to the top of the locking pin 9. A retaining plate 2 is provided above the slope body 1. A circular groove 7 is formed at the top of the retaining plate 2, and the inner diameter of the circular groove 7 matches the inner diameter of the slot 8. A retaining groove 3 is formed on the inner wall of the retaining plate 2, and a roller 4 is slidably connected to the inner wall of the retaining groove 3. A motor 6 is provided on one side of the retaining plate 2, and a roller shaft 18 is inserted into the output shaft of the motor 6. A rubber sleeve is fitted onto the outer wall of the roller 4. The rubber sleeve 5 is used to attach a conveyor belt 19 to the outer circumference of the clamping plate 2. The roller 4 is fixed on the surface of the conveyor belt 19. A rain groove 11 is opened at the bottom of the clamping plate 2. A PP film 12 is adhered to the inner wall of the rain groove 11. The conveyor belt 19 is driven by the motor 6 to drive the roller 4 to slide on the inner wall of the groove 3. This facilitates sliding connection along the groove 3 on the top of the slope body 1, i.e., the surface of the geomembrane 17. The rotating rubber sleeve 5 is used to squeeze the slope body 1 of the geomembrane 17, which can fix the geomembrane 17 and reduce the occurrence of deformation of the geomembrane 17 due to tension, thereby reducing the frequency of damage to the geomembrane 17.

[0035] It is worth noting that, in order to better extend the service life of the slope body 1, specifically, the slope surface and top surface of the slope body 1 are provided with a seepage-proof membrane 17, the top of the slope body 1 is provided with a geomembrane layer 16, the top of the geomembrane layer 16 is provided with a base fabric layer 15, the top of the base fabric layer 15 is provided with an asphalt layer 14, and the top of the asphalt layer 14 is provided with a coating layer 13. Through the superposition and mutual cooperation of the various structural layers, the slope body 1 has a good protective function and good puncture resistance, avoiding external damage that would affect the seepage-proof effect. This facilitates the better extension of the service life of the slope body 1. The structural design of the PP membrane facilitates drainage of the rain trough while providing good protection for the inner wall of the card plate.

[0036] Next, in order to better fix the clamping plate 2 to the top of the slope body 1, there are multiple clamping pins 9, which are symmetrically distributed. Through the structural design of multiple symmetrically distributed clamping pins 9, it is easy to fix the clamping plate 2 to the top of the slope body 1.

[0037] Meanwhile, in order to facilitate better seepage prevention and pressure resistance protection for the slope body 1, specifically, the geomembrane layer 16 is made of polyethylene geomembrane, the base fabric layer 15 is made of self-adhesive waterproof and crack-resistant base fabric, and the coating layer 13 is made of polyurethane coating. The geomembrane layer 16, which is made of polyethylene geomembrane, facilitates better protection for the slope body 1. The base fabric layer 15, which is made of self-adhesive waterproof and crack-resistant base fabric, facilitates better pressure resistance for the slope body 1. The coating layer 13, which is made of polyurethane coating, facilitates better seepage prevention for the slope body 1.

[0038] Finally, in order to achieve a good seepage prevention effect on the slope body 1 while making the slope body 1 relatively lightweight, specifically, the thickness of the geomembrane layer 16, the base fabric layer 15 and the asphalt layer 14 is 5cm, and the thickness of the coating layer 13 is 5mm. By designing the geomembrane layer 16, the base fabric layer 15, the asphalt layer 14 and the coating layer 13 to be relatively thin, it is convenient to achieve a good seepage prevention effect on the slope body 1 while making the slope body 1 relatively lightweight.

[0039] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0040] The device or equipment models mentioned in this article may be as follows:

[0041] Motor: Y802-4.

[0042] Combination Figures 1-6 The specific application process of a landfill slope seepage prevention structure according to this embodiment is as follows:

[0043] 1: When using this type of landfill slope seepage prevention structure, after the staff moves the device to a suitable position, the drive motor 6 causes the conveyor belt 19 to drive the roller 4 and the rubber sleeve 5 to move on the inner wall of the slot 3. This facilitates the sliding connection along the slot 3 on the top of the slope body 1, i.e. the surface of the seepage prevention membrane 17. The rotating rubber sleeve 5 squeezes the slope body 1 of the seepage prevention membrane 17, which plays a role in fixing the seepage prevention membrane 17. This reduces the situation in traditional installation methods where the seepage prevention membrane 17 is easily pulled off by external force. At the same time, the design of the screw pin 9 fixed at the bottom of the nut 10 to connect the threaded groove 7 and the hole groove 8 facilitates the disassembly and fixing of the card plate 2, thus providing a better protective layer for the slope body 1.

[0044] 2. When the slope body 1 needs to achieve a good seepage prevention effect, the structural design of the asphalt layer 14 facilitates better water blocking of the slope body 1. The geomembrane layer 16, made of polyethylene geomembrane, provides good protection for the slope body 1. The base fabric layer 15, made of self-adhesive waterproof and crack-resistant base fabric, provides good compressive strength for the slope body 1. The coating layer 13, made of polyurethane coating, provides good seepage prevention for the slope body 1. The concave-convex connection structure between the various protective layers provides good protection for the slope body 1 and good puncture resistance, while strengthening the connection between the various protective layers to avoid external damage that would affect the seepage prevention effect, thereby extending the service life of the slope body 1.

[0045] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
