Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of geomembranes, in particular to a grid geomembrane. Background Technique
[0002] A geomembrane is a geosynthetic impermeable material composed of a plastic film as an impermeable base material and a non-woven fabric. The impermeability of the new geomembrane mainly depends on the impermeability of the plastic film. Geomembranes are often used in landfills, tailings storage sites, canal seepage prevention, fish pond and lotus pond seepage prevention, dam seepage prevention and subway projects.
[0003] After retrieval, in the prior art, the utility model with the publication number of CN212147823U discloses a high-strength grid geomembrane, including a geomembrane bottom layer, and a first steel wire layer is fixedly connected inside the geomembrane bottom layer. An anti-slip block is fixedly connected to the top of the first steel wire layer and penetrates through the geomembrane bottom layer and the polyester grid and extends to the bottom of the polyester grid. For this high-strength grid geomembrane, by arranging the first steel wire layer inside the geomembrane bottom layer and the polyester grid at the bottom of the geomembrane bottom layer to connect the anti-slip block, and through the anti-slip property of the anti-slip block, the purpose of facilitating the installation of the device is achieved. By arranging a waterproof layer and an anti-damage layer, the purpose of good anti-seepage effect of the device is achieved. By comprehensively using the first steel wire layer, the second steel wire layer and the third steel wire layer arranged inside the geomembrane bottom layer and the geomembrane top layer and the anti-damage layer outside, the purpose of further increasing the strength of the device and preventing the device from being damaged is achieved, which is convenient for the user to use.
[0004] And the prior art, a geomembrane with good anti-microbial property with the publication number of CN213681980U.
[0005] The above-mentioned various technical solutions improve the use effect of the geomembrane in different ways. However, in actual use, two sections of geomembranes laid on the same plane are generally butt-jointed by means of lapping, that is, a part of one section of the geomembrane needs to cover the other section of the geomembrane to prevent the occurrence of gaps between the two sections of the geomembrane due to geological changes, thereby affecting the anti-seepage ability and other abilities of the geomembrane. However, the connection strength of the lapping and covering method is relatively low. If bolt connection is used, it will cause through damage to the geomembrane, affect the integrity of the geomembrane, and reduce the use strength of the geomembrane; and the geomembrane located on the upper layer is prone to curling and other situations, resulting in poor overall practicability. Content of the Utility Model

[0008] Preferably, the grooves and the bumps are both arranged in a matrix at equal intervals, and the grooves are movably connected with the bumps.
[0009] Preferably, the grooves and the bumps are both semi-circular, and a waterproof and sunscreen coating is applied on the surface of the geomembrane main body.
[0010] Preferably, the crack prevention layer is woven by crossing and arranging several aromatic polyamide fibers.

[0015] 2. For this geogrid geomembrane, through the use of the bumps, the bumps are arranged on the side of the geomembrane that fits the ground, which can increase the grip of the geomembrane on the ground, so as to avoid the situation of sliding of the geomembrane during use to a certain extent, thereby improving the use stability.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Example: See Figure 1-2 The utility model provides a technical solution of a grid geomembrane: it includes a geomembrane main body 1, a plurality of grooves 2 are opened on the top of the geomembrane main body 1, a plurality of protrusions 5 are distributed on the bottom of the geomembrane main body 1, and an anti-cracking layer 6 is arranged in the inner cavity of the geomembrane main body 1.
[0021] The grooves 2 and the protrusions 5 are arranged in a matrix with equal distances, and the grooves 2 and the protrusions 5 are movably connected.
[0022] In this embodiment, the protrusion 5 is arranged on the side of the geomembrane that is in contact with the ground. The protrusion 5 increases the grip of the device on the ground, which can avoid the geomembrane from sliding during use to a certain extent, thereby improving the stability of use; when the construction ground requires the laying of two or more sections of geomembranes, first lay a section of geomembrane at an appropriate position, and then cover the edge of another section of geomembrane on top of the laid geomembrane. At this time, the several protrusions 5 provided on the unlaid geomembrane will be snapped into the grooves 2 opened on the laid geomembrane, so that the two sections of geomembrane restrain each other, and then without using bolts to penetrate the geomembrane, the connection strength between the two sections of geomembrane is improved to improve the practicability of the device.
[0023] The groove 2 and the protrusion 5 are both semicircular, and the surface of the geomembrane body 1 is coated with waterproof and sun-proof paint.
[0024] In this embodiment, the semi-circular structure is different from the rectangular structure, and its edge is relatively smooth. When there are significant geological changes, the bump 5 can disengage from the current groove 2 until it re-enters another part of the groove 2 during the continuous geological changes to re-complete the connection of the two geomembranes. This can prevent the connection between the two geomembranes from being torn when there are large geological changes due to being too tightly connected, thereby further enhancing the practicality of the device. Therefore, when the two geomembranes are initially connected, at least three grooves 2 and bumps 5 arranged in the same direction as the overlap are in a clamped state at the overlap to ensure that the two geomembranes will not become disconnected during the normal service life of the geomembrane, thus ensuring the anti-seepage and other properties of the geomembrane. Applying waterproof and sunscreen coatings on the surface of the geomembrane body 1 is used to extend the service life of the device in the natural environment and further enhance the practicality of the device. Moreover, due to the opening of the grooves 2, when sunlight shines on the device at an inclined angle, partial shadows will be generated inside the grooves 2, thereby reducing the area of direct contact between the device and sunlight, reducing the impact of sunlight on the device, and further extending the service life of the device.
[0025] Among them, the anti-cracking layer 6 is woven by cross-arranging a number of aromatic polyamide fibers.
[0026] In this embodiment, the anti-cracking layer 6 is arranged inside the geomembrane body 1, which can improve the tensile capacity of the device. At the same time, the overall structure of the geomembrane is restricted by the anti-cracking layer 6, making the device not easily undergo tearing fractures, thereby further enhancing the use stability of the device. Moreover, aromatic polyamide fibers are relatively heat-resistant and can improve the flame retardancy of the device to a certain extent, thus enhancing the use safety of the device.
[0027] Among them, a through groove 3 is opened in the inner cavity of the geomembrane body 1, and a rubber column 4 is arranged in the inner cavity of the through groove 3.
[0028] Among them, a number of reinforcing ribs 7 are arranged above the geomembrane body 1
[0029] In this embodiment, both the rubber column 4 and the reinforcing ribs 7 are integral structures with good resilience. After the device is laid, it can improve the anti-bending capacity of the device. Moreover, the rubber column 4 can increase the weight on both sides of the geomembrane body 1 to a certain extent, making it not easy for the overlap of the two geomembranes to curl, etc., thereby further enhancing the use stability of the device.
