[0022] 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.

[0023] See also Figure 1 to Figure 4In an embodiment of the utility model, a composite drainage geomembrane that is easy to assemble and connect includes a drainage mesh mat 2, a porous filter layer 1 is adhered to the top and bottom of the drainage mesh mat 2, a plurality of adjacent drainage mesh mats 2 are spliced ​​into a drainage mat, and the adjacent two drainage mesh mats 2 are spliced ​​and assembled through a docking mechanism; a connecting groove 10 is provided on the non-annular portion of the drainage mesh mat 2, and the connecting groove 10 is inserted into the docking mechanism; the docking mechanism includes: a connecting component and a plug-in component; the connecting component is docked with the connecting groove 10, and the plug-in component is used to limit the connecting component that has been docked with the connecting groove 10, and the plug-in component inserted into the connecting component performs self-locking and limiting on the connecting component to avoid separation of the connecting component and the plug-in component.

[0024] In this embodiment: during the production of the geotextile mat, multiple drainage mesh mats 2 are extruded through an extruder, and then two drainage mesh mats 2 are connected through a docking mechanism, and the connecting component in the docking mechanism is first docked with the connecting groove 10, at which time the docking mechanism and the connecting groove 10 are plugged in, and then the plug-in component is plugged in with the docking component, and the plug-in component and the connecting component are self-locked after the plug-in is completed, and at this time, the plug-in component and the connecting component cooperate to complete the connection of the two drainage mesh mats 2;

[0025] Then, the porous filter layer 1 (such as chemical fiber cloth) is pasted on the top and bottom of the drainage mesh mat 2 to complete the production of the device;

[0026] It should be noted that: when the drainage mat 2 is laid on a slope, holes can be punched on the drainage mat 2 by a punching device to facilitate inclined drainage (such as Figure 2 shown).

[0027] Please refer to Figure 4 The connecting component includes a No. 1 connecting plate 3, one end of which is formed with a connecting column 5 that matches the inner wall of the connecting groove 10; the connecting column 5 is open away from the interior of the No. 1 connecting plate 3, and a limiting groove 7 with a ring-shaped structure is provided in the middle section of the inner circumference of the connecting column 5. The plug-in component includes a No. 2 connecting plate 4 symmetrically arranged with the No. 1 connecting plate 3, one end of the No. 2 connecting plate 4 is integrally formed with a plug-in column 6 that is plugged into the inner wall of the connecting column 5, and a receiving groove 8 with a ring-shaped structure is provided in the middle section of the outer circumference of the plug-in column 6; the receiving groove 8 is fixedly connected to a limiting plate 9 at the end of the inner wall of the No. 1 connecting plate 3.

[0028] In this embodiment: first insert the connecting column 5 into the inner wall of the connecting groove 10, and then insert the plug-in column 6 into the interior of the connecting column 5. During the insertion process of the plug-in column 6, the plug-in column 6 drives the limiting plate 9 to move synchronously. When the limiting plate 9 contacts the inner periphery of the opening of the connecting column 5, it is subjected to an extrusion force. At this time, the limiting plate 9 is deformed and enters the interior of the accommodating groove 8 until the accommodating groove 8 is aligned with the limiting groove 7. At this time, the limiting plate 9 is reset under its own deformation and is stuck in the limiting groove 7. The free end of the limiting plate 9 is against the limiting groove 7, completing the mutual self-locking of the plug-in column 6 and the connecting column 5, and ensuring the docking stability of the connecting component and the plug-in component.
