Description

Technical Field

[0001] This application relates to the field of waste landfill technology, and in particular to the field of closed geomembrane technology for landfilling waste. Background Technology

[0002] In the process of landfilling waste, landfills typically use geomembranes as an intermediate covering layer to seal the landfilled waste, achieve rainwater and sewage separation, prevent rainwater from seeping into the waste pile and increasing leachate volume, and at the same time prevent the emission of gases from the pile and pollute the environment.

[0003] When laying large areas of geomembrane on a landfill, it's necessary to place materials on top to weigh it down and prevent it from being blown away by the wind or subjected to tensile creep. Sandbags, tires, and precast concrete blocks are commonly used to weigh down the geomembrane. However, these materials only cover the surface of the geomembrane and can slip under certain conditions. For steep slopes, it's difficult to secure the geomembrane with this weight. The geomembrane covering is only temporary; it needs to be removed when the upper layer of waste is landfilled. This requires cleaning up the sandbags, tires, and concrete blocks, a very laborious task.

[0004] To address the issues of geomembrane fixation and facilitate subsequent removal, a novel anchoring structure for securing geomembranes is needed.

[0005] In some locations where geomembranes are used, anchoring trenches cannot be used to anchor the geomembrane. Simply piling up bricks or sandbags is insufficient, as the sandbags are prone to slipping and are difficult to use effectively to secure the geomembrane. In such cases, a new type of anchoring structure capable of securing the geomembrane is needed. Summary of the Invention

It should be noted that, unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0043] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. The drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation.

[0044] This embodiment provides a geomembrane anchoring device to solve the technical problem that geomembranes are difficult to fix and inconvenient to remove when landfilling waste in the prior art.

[0045] The following will describe in detail the principle and implementation method of the geomembrane anchoring device of this embodiment, so that those skilled in the art can understand the geomembrane anchoring device of the present invention without creative effort.

[0046] like Figures 1 to 6 As shown, this embodiment provides a geomembrane anchoring device 100, which is applied to a waste pile 300 on which a geomembrane 200 is laid. Figure 1 A schematic diagram of the overall structure of the geomembrane anchoring device 100 in this embodiment is shown. Figure 1 As shown, the geomembrane anchoring device 100 includes: a geomembrane sealing cap, a rope one-way fixing lock head 130, an anchor head 140, and an anchoring rope 150.

[0047] The geomembrane anchoring device 100 of this embodiment will be described in detail below.

[0048] In this embodiment, the geomembrane sealing cover includes a lower cover 120 placed on the lower surface of the geomembrane 200 and an upper cover 110 fastened and fixed to the lower cover 120.

[0049] The lower cover 120 and the upper cover 110 are respectively provided with multiple connecting through holes. The multiple connecting through holes are connected by screws or bolts 112 to achieve the fastening and fixing of the lower cover 120 and the upper cover 110.

[0050] In this embodiment, the geomembrane sealing cover consists of an upper cover 110 and a lower cover 120. During use, as follows... Figure 2 As shown, the lower cover 120 is placed on the lower surface of the geomembrane 200. The upper cover 110 and the lower cover 120 are clamped and sealed to cover the geomembrane 200 by connecting parts such as screws or bolts 112, so as to prevent rainwater from entering the waste pile 300 and to prevent landfill gas from evaporating into the air.

[0051] In this embodiment, the geomembrane sealing cap is made of, but is not limited to, plastic or metal. Specifically, the geomembrane sealing cap can be made of plastic, preferably high-density polyethylene, the same material as the geomembrane 200. Other plastic materials with resistance to environmental aging and biochemical corrosion can also be used. Simultaneously, the geomembrane sealing cap can also be made of metal, including but not limited to zinc-aluminum alloys, stainless steel, etc.

[0052] In this embodiment, a sealing gasket is provided on the snap-fit ​​contact surface between the upper cover 110 and the lower cover 120. That is, the geomembrane sealing cover is equipped with a sealing gasket, which is preferably made of rubber-based material, but other materials with sealing properties, such as EPDM, can also be used. Furthermore, in this embodiment, the geomembrane sealing cover is conventionally elliptical, with a size between 100mm and 300mm. Other sizes and other arbitrary shapes are also possible.

[0053] In this embodiment, the one-way rope fixing lock head 130 is fixed to the lower cover 120 and is used to control the movement direction of the anchor rope 150 when the anchor head 140 moves within the waste pile 300.

[0054] Specifically, in this embodiment, as Figure 3 As shown, the rope unidirectional fixing lock 130 includes at least: a lock body 131, a through hole 132, a limiting post 133, and an elastic body 134.

[0055] In this embodiment, the lock body 131 is connected to the lower cover 120 of the geomembrane sealing cover and is embedded in the lower cover 120 of the geomembrane sealing cover to fix the geomembrane sealing cover by the anchoring rope 150. The shape of the lock body 131 is not limited.

[0056] In this embodiment, the through hole 132 is disposed in the lock body 131, penetrating the lock body 131, for the anchoring rope 150 to pass through. The limiting post 133 is disposed in the through hole 132, used to restrict the upward movement of the anchoring rope 150. The elastic body 134 is disposed below the limiting post 133, so that when the anchoring rope 150 moves downward, it drives the limiting post 133 to move downward.

[0057] The elastomer 134 is preferably a spring.

[0058] In this embodiment, the diameters at both ends of the through hole 132 are smaller than the diameter in the middle; the middle of the through hole 132 has a receiving cavity for accommodating the limiting post 133 and the elastic body 134. The receiving cavity includes a first receiving portion and a second receiving portion; the diameter of the first receiving portion increases downwards from the top of the through hole 132; the diameter of the second receiving portion is a fixed value.

[0059] In other words, in this embodiment, the upper part of the receiving cavity has an aperture that gradually increases from top to bottom, forming a funnel-shaped receiving cavity, while the middle and lower parts of the receiving cavity have equal aperture sizes, forming a cylindrical receiving cavity.

[0060] Supported by the elastic body 134, the limiting post 133 is positioned at a high point. At this high point, the diameter of the limiting post 133 and the anchoring rope 150 is equal to or slightly smaller than the diameter of the through hole 132. This means that when the anchoring rope 150 moves upward, the limiting post 133 cannot continue to move upward because the diameter of the through hole 132 becomes smaller, creating a compression state between the limiting post 133 and the anchoring rope 150, thus restricting the upward movement of the anchoring rope 150. When the anchoring rope 150 moves downward, the diameter of the through hole 132 increases, and the limiting post 133 no longer compresses the anchoring rope 150, allowing the anchoring rope 150 to move downward continuously. Therefore, in this embodiment, the one-way rope locking head 130 controls the anchoring rope 150 to move downward but not upward, achieving one-way rope control.

[0061] Therefore, in this embodiment, the one-way rope lock head and the anchor head 140 are connected by the anchor rope 150. The function of the one-way rope locking head 130 is to restrict the anchor rope 150 to move in only one direction.

[0062] In this embodiment, the one-way rope locking head 130 is made of plastic or metal. The one-way rope locking head 130 is preferably made of a plastic material resistant to biochemical corrosion. Metal materials can also be used, including but not limited to zinc-aluminum alloys, stainless steel, etc.

[0063] Furthermore, in this embodiment, the anchoring rope 150 can also be controlled to move upward. Specifically, as shown... Figure 3 As shown, the rope unidirectional fixing lock head 130 also includes an unlocking hole 135, which is located at the top of the lock body 131 and aligned with the limiting post 133. The unlocking hole 135 is used to press the limiting post 133 downward, so that the anchoring rope 150 can move upward.

[0064] In other words, in this embodiment, the spring presses against the limiting post 133, preventing the anchoring rope 150 from being pulled upwards. When the anchoring rope 150 is pulled downwards, the limiting post 133 moves downwards, allowing the anchoring rope 150 to slide downwards. Through the unlocking hole 135, a pin or other device is used to press against the limiting post 133, compressing it downwards, thereby preventing the limiting post 133 from squeezing the anchoring rope 150 and allowing the anchoring rope 150 to be pulled upwards.

[0065] In this embodiment, the anchoring rope 150 is pre-installed between the anchoring head 140 and the one-way rope fixing lock 130. The function of the anchoring rope 150 is to fix the anchoring head 140 and the geomembrane sealing cover. One end of the anchoring rope 150 is fixed to the anchoring head 140, and the other end passes through the one-way rope fixing lock 130 and is fixed to the lower cover 120 of the geomembrane sealing cover. The anchoring rope 150 is a steel wire rope or a plastic rope. The anchoring rope 150 is generally made of corrosion-resistant steel wire rope, but high-strength plastic rope can also be used. The anchoring rope 150 typically uses steel wire rope with a thickness of 3mm to 10mm.

[0066] In this embodiment, as Figure 4 As shown, the anchor head 140 has a pointed tip for insertion into the waste pile 300 or soil under the geomembrane. When the anchor rope 150 moves upward, the anchor head 140 changes direction, restricting its own movement and achieving the purpose of anchoring.

[0067] Specifically, in the embodiment, the anchor head 140 is provided with a first connecting hole for connecting the anchor rope 150 and a second blind hole for connecting the drive rod 160 that drives the anchor head 140 to be inserted into the waste pile 300.

[0068] In this embodiment, one end of the anchor head 140 is pointed, allowing it to be inserted into the waste pile 300. The anchor head 140 has a first connecting hole through which the anchor rope 150 can pass. The anchor head 140 also has a circular hole, a second blind hole, through which a driving rod 160, such as a metal pipe, can be inserted. For example, an impact hammer can be used to control the driving rod 160, driving the anchor head 140 into the waste pile 300. After the anchor head 140 is driven into the waste pile 300, pulling the anchor rope 150 upwards changes the anchor head 140 from a vertically downward position to a horizontal position, making it difficult to pull out.

[0069] In this embodiment, the anchor head 140 is made of a plastic material resistant to biochemical corrosion. Metal materials, including but not limited to zinc-aluminum alloys and stainless steel, can also be used.

[0070] To enable those skilled in the art to further understand the geomembrane anchoring device 100 of this embodiment, the following is combined with Figure 5and Figure 6 The usage process of the geomembrane anchoring device 100 in this embodiment will be further explained.

[0071] Before applying the geomembrane anchoring device 100 of this embodiment, a pre-set cut is made on the geomembrane 200 using a mold covering the opening of the geomembrane 200. The lower cover 120 is then inserted under the geomembrane 200 through the cut, and its orientation and position are adjusted so that its length follows the direction of the cut, exposing the screw holes (connection through holes) used for connection. Figure 5 As shown, the anchor head 140 is fitted with an auxiliary steel pipe, and inserted into the waste pile 300 with the pointed end of the anchor head 140 facing downwards. For example, a manual vibratory hammer or impact hammer is used to drive the anchor head 140 into the waste pile 300 until most of the anchor rope 150 is inside the waste pile 300 and the anchor head 140 is also mostly inside the waste pile 300, reaching the target fixed position. Then, the anchor rope 150 is pulled upwards, and the anchor head 140 changes from a downward-pointing position to a horizontal position. The anchor head 140 restricts the anchor rope 150 from being pulled outwards. In other words, the anchor head 140 is inserted vertically downwards into the waste pile 300. After reaching the final position, the anchor rope 150 is pulled upwards, and the anchor head 140 changes from a vertical to a horizontal position, thus fixing the anchor rope 150 and preventing it from moving upwards. Figure 6 As shown. Trim off excess anchoring rope 150. Adjust the sealing lower cover 120 to a suitable position, and fix the upper cover 110 and lower cover 120 with screws, thus completing the installation of a single geomembrane anchoring device 100. Therefore, in this embodiment, the geomembrane anchoring device 100 achieves the fixation of the geomembrane 200 when landfilling waste by inserting the anchor head 140 into the waste pile 300, connecting the anchor head 140 to the lower cover 120 located on the lower surface of the geomembrane 200 through the anchoring rope 150, and sealing the lower cover 120 with the upper cover 110.

[0072] When the upper layer of waste needs to be buried in the middle layer of the landfill, the covering geomembrane 200 needs to be removed. To remove the geomembrane 200, open the upper cover 110 of the geomembrane sealing cover, cut the anchoring rope 150, and then remove the lower sealing cover 120. After removing the lower cover 120, the covering geomembrane 200 can be removed. Therefore, when it is necessary to remove the geomembrane 200, in this embodiment, the geomembrane anchoring device 100 only needs to disconnect the anchoring rope 150 to remove the geomembrane sealing cover and remove the geomembrane 200, which is very convenient.

[0073] This embodiment also provides a geomembrane 200 anchoring system, including multiple geomembrane anchoring devices 100 as described above; wherein, the multiple geomembrane anchoring devices 100 are connected in series by an anchoring rope 150. Multiple geomembrane anchoring devices 100 can be connected together using the anchoring rope 150 to form a fixed connection body, thereby achieving the fixation of a large area of ​​geomembrane 200.

[0074] It should be noted that the structure and principle of the geomembrane anchoring device 100 used to implement this embodiment are not limited to... Figures 1 to 6 All reasonable modifications made by those skilled in the art based on the ideas of this application to the structure shown herein should be considered within the scope of protection of this application.

[0075] In summary, this application achieves geomembrane fixation during landfilling by inserting an anchor head into the waste pile, connecting the anchor head to a lower cover placed on the underside of the geomembrane via anchor ropes, and sealing the lower cover with an upper cover. When the geomembrane needs to be removed, this application only requires disconnecting the anchor ropes to remove the geomembrane sealing cover and then removing the geomembrane. This application features a simple structure, convenient fixing and removal, and strong practicality and economy. Therefore, this application effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
