Composite geomembrane is divided into one cloth and one membrane and two cloths and one membrane, with a width of 4-6m and a weight of 200-1500g / m2. It has high physical and mechanical properties such as tensile strength, tear resistance, and bursting resistance, and can meet the needs of civil engineering such as water conservancy, municipal administration, construction, transportation, subway, and tunnels.

[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] See also Figures 1 to 3 In the embodiment of the utility model, a composite geomembrane that is convenient to connect includes a composite geomembrane body 1, both ends of the composite geomembrane body 1 are provided with side grooves 2, the two side grooves 2 are respectively located on the upper and lower sides of the two ends of the composite geomembrane body 1, and a connecting component 3 is provided between the two side grooves 2 for pre-connecting two sheets of the composite geomembrane body 1;

[0021] The composite geomembrane body 1 comprises a base layer 101, and both side ends of the base layer 101 are adhered with a protective layer 102, and the outer sides of the two protective layers 102 are adhered with a wear-resistant layer 103;

[0022] The connection assembly 3 includes at least one first docking member 301 adhered to one end of the base layer 101 , and a second docking member 302 adhered to the other end of the base layer 101 and matched with the first docking member 301 .

[0023] The base layer 101 is made of PVC polyethylene plastic film; the protective layer 102 is filled with flame retardant; and the wear-resistant layer 103 is a textile fabric made of nylon.

[0024] In this embodiment: Since the existing process of overlapping the side seams needs to ensure that both sides are aligned and flat, this process takes a lot of time. In addition, the stability of the connection at the welding point is also poor. Therefore, this scheme sets a connecting component 3 between the two ends of the composite geomembrane body 1, and uses the connecting component 3 to pre-connect and fix the two adjacent composite geomembrane bodies 1, and then uses a geomembrane welding machine to heat weld the pre-connection between the two composite geomembrane bodies 1, thereby not only making the connection between the two composite geomembrane bodies 1 more stable, but also making the connection between the two composite geomembrane bodies 1 smooth and beautiful.

[0025] Specifically, the composite geomembrane in this solution mainly includes a composite geomembrane body 1, two side grooves 2 and a connection component 3. The composite geomembrane body 1 is composed of a base layer 101, a protective layer 102 and a wear-resistant layer 103, which are bonded together by glue. The protective layer 102 and the wear-resistant layer 103 can play a good protective role on the base layer 101, thereby improving the overall service life of the composite geomembrane body 1. The two side grooves 2 are respectively opened at both ends of the composite geomembrane body 1, and one of them is opened on the upper surface of one end of the composite geomembrane body 1, and the other is opened on the lower surface of one end of the composite geomembrane body 1, so that when two adjacent composite geomembrane bodies 1 are butt-jointed, the connection between the two composite geomembrane bodies 1 and the composite geomembrane body 1 can maintain flatness. In addition, the connection components 3 are scattered on the two side grooves 2. The connection components 3 mainly include a first docking piece 301 and a second docking piece 302. By utilizing the snap-fit ​​connection structure between the first docking piece 301 and the second docking piece 302, the two composite geomembrane bodies 1 can be easily pre-connected, thereby facilitating the connection and fixation of subsequent processes.

[0026] Please refer to Figure 2 The second docking member 302 is provided with a clamping groove matching the shape of the first docking member 301 , and both the first docking member 301 and the second docking member 302 are made of hot melt adhesive.

[0027] In this embodiment: since the first butt joint member 301 and the second butt joint member 302 are both made of hot melt adhesive, the hot melt adhesive can be deformed by a certain force, so the first butt joint member 301 can be inserted into the clamping groove on the second butt joint member 302, so that the first butt joint member 301 and the second butt joint member 302 are closely connected, which is convenient for realizing simple pre-connection of the two composite geomembrane bodies 1. It should be noted that the connection component 3 is closely adhered to the base layer 101 by glue.

[0028] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
