Description

Technical Field

[0001] This utility model relates to the field of composite geomembrane technology, and in particular to a high-temperature resistant composite geomembrane. Background Technology

[0002] In the field of geotechnical engineering, geomembranes are an indispensable basic material, widely used in many fields such as water conservancy, environmental protection, and transportation.

[0003] During the laying process, traditional geomembranes are prone to warping on both sides due to external forces such as wind, which can lead to uneven laying and affect the project results. Moreover, during splicing, there are also problems such as loose splicing and inaccurate positioning, which bring many inconveniences to the construction.

[0004] Therefore, a high-temperature resistant composite geomembrane is provided to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a high-temperature resistant composite geomembrane.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-temperature resistant composite geomembrane includes a geomembrane body, wherein the geomembrane body is elongated and includes:

[0008] The geomembrane body includes geotextile one and geotextile two, which are connected by hot-melt bonding.

[0009] Two sets of bottom anti-slip strips are installed on the second geotextile, and the two sets of bottom anti-slip strips are respectively located on the longer sides of the first geotextile.

[0010] Four sets of top anti-slip strips are installed on the geotextile one. The four sets of top anti-slip strips are located at the four corners of the geotextile two. The two geomembrane bodies can be spliced ​​and connected by the contact between the bottom anti-slip strips and the top anti-slip strips.

[0011] To further improve the anti-slip capability, preferably, both the bottom anti-slip strip and the top anti-slip strip are provided with multiple sets of anti-slip protrusions.

[0015] To improve high-temperature resistance, preferably, the surfaces of geotextile one and geotextile two are coated with polysiloxane resin.

[0016] Compared with the prior art, this utility model provides a high-temperature resistant composite geomembrane, which has the following beneficial effects:

[0017] This invention improves the stability of the connection between the geomembrane and the object surface during the laying process by setting a bottom anti-slip strip on the geomembrane body, reducing the lifting caused by strong winds.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example:

[0027] Reference Figure 1-6 A high-temperature resistant composite geomembrane includes a geomembrane body, which is elongated and includes: geotextile 1 and geotextile 2, which are connected by heat fusion bonding; two sets of bottom anti-slip strips 4, which are installed on geotextile 2 and located on the longer sides of geotextile 1; and four sets of top anti-slip strips 5, which are installed on geotextile 1 and located at the four corners of geotextile 2. The two geomembrane bodies can be spliced ​​and connected by the contact between the bottom anti-slip strips 4 and the top anti-slip strips 5.

[0028] Multiple sets of anti-slip protrusions 6 are provided on both the bottom anti-slip strip 4 and the top anti-slip strip 5.

[0029] Geotextile 1 and Geotextile 2 are made of high-density polyethylene film, and the bottom anti-slip strip 4 and the top anti-slip strip 5 are made of polyethylene or polypropylene.

[0030] Multiple sets of reinforcing bars 3 are provided between geotextile 1 and geotextile 2.

[0031] Multiple sets of reinforcing ribs are arranged in a grid pattern.

[0032] The surfaces of geotextile 1 and geotextile 2 are coated with polysiloxane resin.

[0033] The geomembrane body is formed by hot-melt bonding of geotextile 1 and geotextile 2. This bonding method ensures a tight bond between the two geotextile layers, enhancing the overall strength and stability.

[0034] Multiple sets of grid-shaped reinforcing ribs 3 are installed between geotextile 1 and geotextile 2. The reinforcing ribs 3 further improve the tensile strength and deformation resistance of the geomembrane, making it less prone to damage when subjected to large loads.

[0035] Two sets of bottom anti-slip strips 4 are installed on geotextile 2, located on the longer sides of geotextile 1 respectively.

[0036] The bottom anti-slip strip 4 is provided with multiple sets of anti-slip protrusions 6. These protrusions can increase the friction between the geomembrane and the laying surface, and prevent the geomembrane from sliding during the laying or use process.

[0037] Four sets of top anti-slip strips 5 are installed on geotextile 1, located at the four corners of geotextile 2. The top anti-slip strips 5 are also equipped with multiple sets of anti-slip protrusions 6. When splicing geomembranes, the top anti-slip strips 5 contact the bottom anti-slip strips 4 of the adjacent geomembranes. Positioning and tight connection are achieved through the mutual contact of the anti-slip protrusions 6.

[0038] In addition, the surfaces of geotextile 1 and geotextile 2 are coated with polysiloxane resin, which has excellent high temperature resistance, weather resistance and chemical stability, further improving the high temperature resistance and service life of the geomembrane.

[0039] When laying the geomembrane, the ground to be laid should be cleaned to remove debris, dust, oil, and other contaminants from the surface.

[0040] Then check the ground moisture. If the ground is too dry, spray some water to keep the ground moist, which helps to enhance the adhesion between the geomembrane and the ground.

[0041] Unfold the high-temperature resistant composite geomembrane, which is usually packaged in a roll. Pull out one end and lay it flat on the pre-treated ground. During the laying process, use the friction between the bottom anti-slip strip 4 and the ground to ensure that the geomembrane can be stably attached to the ground and reduce the phenomenon of lifting caused by strong winds. Try to spray water on the ground to increase the adhesion.

[0042] When one set of geomembrane has been laid and another set of geomembrane needs to be spliced, align the bottom anti-slip strip 4 of the other set of geomembrane with the top anti-slip strip 5 of the geomembrane already laid on the ground. Since both the top anti-slip strip 5 and the bottom anti-slip strip 4 are provided with anti-slip protrusions 6, they can interlock with each other to achieve positioning and make the two sets of geomembranes more tightly connected together.

[0043] During the splicing process, a suitable amount of water can be sprayed on the contact areas of the anti-slip strips. The water can increase the moisture between the anti-slip strips, thereby improving their adhesion and further enhancing the stability of the splicing.

[0044] After the geomembrane is laid and spliced, pressure plates are placed at both ends of the geomembrane. The pressure plates should be heavy enough to effectively hold down both ends of the geomembrane and prevent it from being blown away by strong winds.

[0045] This invention improves the stability of the connection between the geomembrane and the object surface by setting a bottom anti-slip strip 4 on the geomembrane body, reducing the lifting caused by strong winds during the laying of the geomembrane. At the same time, the top anti-slip strip 5 allows the two sets of geomembranes to be tightly connected by contact with the bottom anti-slip strip 4, making it easier for the geomembrane to be spliced ​​and used.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
