Description

Technical Field

[0001] This utility model relates to the field of landfill technology, and in particular to a membrane ballast structure. Background Technology

[0002] After fly ash products are sorted and processed in landfills, they require intermediate covering and ballast application using HDPE membranes. Currently, the most commonly used ballast materials in the industry are waste tires and sandbags, typically applied individually or bound together with nylon ropes. Individual ballast is insufficient to provide adequate load-bearing capacity to the membrane surface. Due to the large area of ​​landfills, if a mesh-like ballast system cannot be implemented, wind can enter through small gaps between the landfill material and the membrane, widening the gaps and causing bulging. Over time, this can even tear the membrane, exposing the landfill material directly to the environment and causing pollution.

[0003] Chinese patent document CN215879190U discloses a membrane ballast structure, including an anti-corrosion rope and multiple prefabricated blocks. Each prefabricated block has a horizontally placed connector, which is integrally formed with the prefabricated block. The anti-corrosion rope is wound around the outer periphery of the connector to enable the multiple prefabricated blocks to be connected in series. The applicant has found some drawbacks in this technical solution:

[0004] 1) Due to the softness of the anti-corrosion rope, during installation, it is necessary to first determine the distance between two adjacent precast blocks and place them in the correct position, and then connect the two adjacent precast blocks with the anti-corrosion rope. This installation process is complicated, and the distance determination is greatly affected by human factors. When a large number of precast blocks are combined, the spacing is easy to be uneven and the standardization is low.

[0005] 2) Although the anti-corrosion rope can prevent corrosion, it is susceptible to damage or wear from extreme weather such as rain, high temperature and freezing during long-term use, which increases the material and manpower maintenance costs of on-site membrane covering.

[0006] 3) When maintenance is required for a single area, the anti-corrosion rope is connected by multiple turns to ensure a secure connection, which makes disassembly inconvenient and reduces work efficiency. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a membrane ballast structure that is simple to install, highly standardized and low in cost.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A membrane ballast device includes multiple prefabricated blocks and multiple spaced steel cables, wherein the spaced steel cables are connected between two adjacent prefabricated blocks to realize the series connection of multiple prefabricated blocks.

[0010] As a further improvement to the above technical solution:

[0011] The precast block is provided with at least two first connectors, and the two ends of the fixed-distance steel cable are provided with second connectors for detachable connection with the first connectors.

[0012] The first connector is a female latch, and the second connector is a female latch.

[0013] Both the first connector and the second connector are made of stainless steel.

[0014] Each of the first connecting members is arranged at uniform intervals along the circumference of the precast block.

[0015] The first connector has four parts, and the prefabricated blocks are connected in series to form a mesh-like ballast structure.

[0016] It also includes a connecting cable, one end of which is embedded in the precast block and the other end is connected to the first connector.

[0017] The connecting cable is located at the bottom of the precast block.

[0018] The connecting cable is integrally formed with the precast compression block.

[0019] The length of the fixed-distance steel cable is 3m.

[0020] Compared with the prior art, the advantages of this utility model are:

[0021] 1. The membrane ballast structure of this utility model uses prefabricated pressure blocks connected in series with fixed-distance steel cables. Compared with anti-corrosion ropes, it is harder and has a fixed length. It is easy to fix the distance, the installation process is simple, and the standardization is high. In addition, the steel cables are not easy to wear during long-term use, and the cost is low.

[0022] 2. In the membrane ballast structure of this utility model, the prefabricated pressure block and the fixed-distance steel cable are detachably connected by connectors, which makes disassembly convenient and improves work efficiency. Attached Figure Description

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figures 1 to 3 As shown, the membrane ballast structure of this embodiment includes multiple prefabricated blocks 1 and multiple spaced steel cables 4. The spaced steel cables 4 are connected between two adjacent prefabricated blocks 1 to realize the series connection of multiple prefabricated blocks 1.

[0032] In this embodiment, the membrane ballast structure uses fixed-distance steel cables 4 to connect the prefabricated pressure blocks 1 in series. Compared with anti-corrosion ropes, these cables are harder, have a fixed length, are easy to space, are simple to install, have a high degree of standardization, and are not easily worn during long-term use, resulting in low cost.

[0033] Furthermore, in this embodiment, the precast block 1 is provided with at least two first connectors 2, and the two ends of the spaced steel cable 4 are provided with second connectors 3 for detachable connection with the first connectors 2. The precast block 1 and the spaced steel cable 4 are detachably connected through the connectors, which is convenient for disassembly and has high work efficiency.

[0034] Furthermore, in this embodiment, the first connecting member 2 is a female locking buckle, and the second connecting member 3 is a female locking buckle. By fastening the female locking buckle to the female locking buckle, the connection between the fixed-distance steel cable 4 and the prefabricated pressure block 1 can be achieved, ensuring reliable connection and simple installation and disassembly. Of course, in other embodiments, the first connecting member 2 and the second connecting member 3 can be other connection forms such as magnetic attraction or bolt connection.

[0035] Furthermore, in this embodiment, both the first connector 2 and the second connector 3 are made of stainless steel, which is not easily damaged and has a long service life.

[0036] Furthermore, in this embodiment, each first connector 2 is evenly spaced along the circumference of the precast blocks 1; there are four first connectors 2, and multiple precast blocks 1 are connected in series to form a mesh-like ballast structure. The four first connectors 2 are arranged in four directions of the precast blocks 1, so that multiple precast blocks 1 can be connected in series in the transverse and longitudinal directions, thereby combining to form a mesh structure with good ballast effect.

[0037] Furthermore, this embodiment also includes a connecting cable 5, one end of which is embedded in the prefabricated pressure block 1, and the other end is connected to the first connecting member 2. By connecting the first connecting member 2 to the connecting cable 5, when the first connecting member 2 is worn, it can be simply removed from the connecting cable 5 and replaced, which is simple and easy to use.

[0038] Furthermore, in this embodiment, the connecting cable 5 is located below the precast pressure block 1. This allows the spaced steel cable 4 to be closer to the membrane surface, reducing the risk of tripping for workers when maintaining the membrane surface.

[0039] Furthermore, in this embodiment, the connecting cable 5 is integrally formed with the precast pressure block 1. The connecting cable 5 is embedded in the precast pressure block 1, resulting in a stable structure.

[0040] Furthermore, in this embodiment, the length of the fixed-distance steel cable 4 is 3m. In other embodiments, the length of the fixed-distance steel cable 4 can be adaptively adjusted according to the actual coverage of the landfill.
