Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, and in particular to a composite geomembrane anchoring and seepage prevention structure. Background Technology
[0002] Composite geomembrane anchoring seepage prevention structures are key structures used in water conservancy, municipal, and environmental protection projects to fix composite geomembranes (composed of geotextiles and geomembranes, possessing both seepage prevention and tensile strength properties), prevent their displacement or leakage, and enhance the overall integrity of the seepage prevention system. Their core function is "dual protection of fixation and seepage prevention," avoiding the risk of leakage caused by warping of the composite geomembrane edges, loosening of joints, or detachment from the foundation structure.
[0003] Chinese Patent Publication No. CN221297812U discloses a composite geomembrane anchoring seepage prevention structure, comprising anchor blocks, micro-expansion concrete, and a composite geomembrane. This anchoring seepage prevention structure is installed in an anchoring trench carved into the concrete base of an artificial wetland. The anchoring trench has a rectangular cross-section. The composite geomembrane consists of a sidewall section, a bottom section, and a folded section. The sidewall section is laid on one side wall of the anchoring trench; the bottom section is laid at the bottom of the anchoring trench; and the folded section is bent and folded within the anchoring trench. The micro-expansion concrete fills the space in the anchoring trench excluding the composite geomembrane. The seepage prevention structure provided by this invention has a simple process and low cost, while overcoming the problems of easy damage to the composite geomembrane and difficult subsequent maintenance during existing composite geomembrane anchoring.
[0004] Existing composite geomembrane anchoring seepage prevention structures connect anchor blocks to the pool wall base layer and then to the composite geomembrane. If the pool wall base layer is soft soil or the pool wall foundation settles, it can easily lead to the anchor blocks shifting and cracking, which in turn can tear the composite geomembrane. At the same time, composite geomembrane anchoring seepage prevention structures are not convenient for real-time leakage warning functions during use, which reduces the service life of the composite geomembrane anchoring seepage prevention structure.

[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0026] Example 1
[0027] like Figure 1 - Figure 3 As shown, the present invention proposes a composite geomembrane anchoring seepage prevention structure, comprising: a seepage prevention component and a conductive fiber mesh layer 6; the seepage prevention component includes an mounting block 1, a connector, a connecting block 106, a crushed stone cushion layer 2, a pool wall base layer 3, reinforcing steel bars 4, and a composite geomembrane body 5; the mounting block 1 is connected to the connecting block 106 via the connector, and the mounting block 1 and the connecting block 106 are connected to form an anchoring block; the crushed stone cushion layer 2 is laid below the anchoring block and on the pool wall base layer 3; the reinforcing steel bars 4 pass through the anchoring block and the crushed stone cushion layer 2 and are connected to the pool wall base layer 3, and the composite geomembrane body 5 is laid on the anchoring block; the conductive fiber mesh layer 6 is connected to the composite geomembrane body 5. By adding a conductive fiber mesh layer 6 to the composite geomembrane body 5, it is easier to increase the structural early warning function and improve the service life of the composite geomembrane anchoring and seepage prevention structure. By laying a crushed stone cushion layer 2 between the anchor block and the pool wall base layer 3, it is easier to reduce the problem of anchor block directional deviation and further improve the use of the composite geomembrane anchoring and seepage prevention structure. The anchor block is made of fiber-reinforced concrete with an appropriate amount of polypropylene fiber added to improve the crack resistance and toughness of the anchor block and cope with stress changes caused by slight settlement of the base layer.
[0028] Further explanation: The connector includes a reserved hole 101, an injection hole 102, a cavity 103, a limiting groove 104, and a limiting block 105; the reserved holes 101 are evenly provided on the mounting block 1 and the connecting block 106, the injection hole 102 is provided on the mounting block 1, and the connecting end faces of the mounting block 1 and the connecting block 106 are respectively provided with cavities 103, and the cavity 103 of the mounting block 1 is connected to the injection hole 102; the limiting groove 104 is provided on the mounting block 1, and the limiting block 105 is provided on the connecting block 106; the limiting block 105 is connected in the limiting groove 104, and one end of the reinforcing steel bar 4 passes through the reserved hole 101 and is connected to the crushed stone cushion layer 2 and the pool wall base layer 3. During the installation of the anchor block 1 and the connection of the anchor block 106, the limiting block 105 and the limiting groove 104 are first pre-installed. Then, the two cavities 103 are connected relative to each other. Concrete is injected into the cavity 103 through the injection hole 102 to complete the assembly and connection of the anchor block. After the anchor block is completed, one end of the reinforcing steel bar 4 is passed through the reserved hole 101 and connected to the crushed stone cushion layer 2 and the pool wall base layer 3. This fixes one end of the reinforcing steel bar 4 in the pool wall base layer 3, which facilitates the fixing and limiting of the anchor block, reduces the displacement of the anchor block, and improves the overall use of the composite geomembrane anchoring seepage prevention structure.
[0029] To further explain, multiple composite geomembrane bodies 5 are laid and connected to the anchor blocks. The edges of two adjacent composite geomembrane bodies 5 overlap, with an overlap width of at least 10cm. After the composite geomembrane bodies 5 are laid, professional workers use a geomembrane-specific welding machine to weld the overlapping composite geomembrane bodies 5 into a single unit according to requirements. Then, the entire composite geomembrane is inspected to check for any missed welds or breaks, and repairs are made promptly to complete the composite geomembrane laying work.
[0030] Example 2
[0031] like Figure 1 As shown, the composite geomembrane anchoring and seepage prevention structure proposed in this utility model, based on the above embodiments, also details the specific components such as the conductive fiber mesh layer 6, and their arrangement.
[0032] To further explain, the conductive fiber mesh layer 6 is laid on the composite geomembrane body 5. One side of the conductive fiber mesh layer 6 is connected to the protective shell 601. The conductors 602 of the conductive fiber mesh layer 6 are connected to external equipment by passing through the protective shell 601. The protective shell 601 uses a waterproof and pressure-resistant structure to facilitate the passage of the conductors 602, thus protecting them. The core principle in selecting the conductive fiber mesh layer 6 is to choose according to specific needs and provide targeted protection. For short-term, clean water environments (such as freshwater testing scenarios), ordinary carbon-based or galvanized fiber mesh is sufficient. For long-term, corrosive water environments (such as seawater and sewage), corrosion-resistant materials should be prioritized, and anti-polarization and anti-microbial treatments should be implemented. To maintain conductivity, the water resistivity must be controlled, insulation layer damage must be avoided, and stable current conduction must be ensured.
[0033] To further explain, the pool wall base layer 3 is connected to the pool wall body 7, and one side of the connecting block 106 is connected to the artificial wetland base layer 8. The pool wall body 7 is connected to the side where the connecting block 1 is installed. The artificial wetland base layer 8 is covered with filler material, which is simultaneously laid on the conductive fiber mesh layer 6, so that the filler material is inside the anchor block, and aquatic plants can be planted on the filler material.
[0034] The working principle of this utility model is as follows: When the composite geomembrane anchoring seepage prevention structure is constructed and used, anchor blocks are connected in the pre-pit of the pool wall base layer 3, and then multiple composite geomembrane bodies 5 are laid on the anchor blocks to cover the anchor blocks. Then, a conductive fiber mesh layer 6 is laid on the bottom composite geomembrane body 5. The conductive fiber mesh layer 6 is connected to an external early warning device through a wire 602. When the composite geomembrane is damaged and water seeps into the contact fiber mesh, the early warning device will alarm in real time and locate the damaged area, so that the staff can repair it in time. The core components of the conductive fiber mesh layer 6 (chemical fiber base, metal base, carbon base, etc.) do not have an essential conflict with the physical and chemical effects of water, and the combination of water and conductive fiber mesh can achieve functional complementarity. Under long-term use in contact with water, the conductive fiber mesh layer 6 needs to be inspected and maintained regularly. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
