Description

Technical Field

[0001] The invention belongs to the field of geomembrane laying devices, in particular to a composite geomembrane laying device. Background Art

[0002] Geomembrane is a geotechnical anti-seepage material that is made of plastic film as the anti-seepage base material and non-woven fabric. Its main mechanism is to use the impermeability of the plastic film to block the leakage channel of the earth dam, and to withstand water pressure and adapt to the deformation of the dam body with its large tensile strength and elongation; non-woven fabric is also a kind of polymer short fiber chemical material, which has high tensile strength and elongation through needle punching or hot bonding. When combined with plastic film, it not only increases the tensile strength and puncture resistance of the plastic film, but also increases the friction coefficient of the contact surface due to the rough surface of the non-woven fabric, which has the effect of It is beneficial to the stability of the geomembrane protective layer. Composite geomembrane combines the advantages of geotextiles and geomembranes, and has excellent mechanical properties, waterproof properties and durability. Due to its superior comprehensive performance, composite geomembranes have been widely used in various engineering projects. In the prior art, geomembranes are laid by manual rolling. Due to the large weight and volume of geomembranes, multiple people are required to cooperate in the operation, and the labor cost is high. Moreover, it is difficult to achieve force balance during manual operation, so the laying is difficult, time-consuming and labor-intensive. Therefore, a composite geomembrane laying device is needed.

[0003] The existing composite geomembrane laying device has certain disadvantages when in use. When in use, the existing composite geomembrane laying device usually adopts a clamping device to position the geomembrane and cooperates with a transmission device for auxiliary laying. Although the laying of the geomembrane can be achieved, during the laying of the composite geomembrane, the composite geomembrane is laid in a relaxed state, and this state easily leads to a low degree of fit between the composite geomembrane and the installation ground, which makes it easier for bubbles to appear between the composite geomembrane and the installation ground, thereby reducing the laying effect of the composite geomembrane.
