Description
Technical Field
The utility model relates to a waterproof blanket technical field especially relates to a tectorial membrane waterproof blanket.
Background
The waterproof blanket is a new type geosynthetic material. The natural sodium bentonite particles after grading and corresponding additives are mixed as raw materials, and the bentonite particles are fixed between the geotextile and the plastic woven cloth through a needling process and equipment to prepare the blanket-shaped waterproof coiled material. The bentonite waterproof blanket not only has all the characteristics of the geotechnical material, but also has excellent waterproof performance.
At present, in the production and transportation and use processes, bentonite particles can leak from the thin non-woven fabric below, so that the production is difficult, and in addition, the bentonite inside is easy to fall off when the waterproof carpet is used, so that the waterproof capacity of the waterproof carpet is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: in the process of production, transportation and use, bentonite particles can leak from the thin non-woven fabric below, which not only causes difficulty in production, but also reduces the waterproof capability of the waterproof blanket because the bentonite inside is easy to fall off when in use.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a tectorial membrane waterproof blanket, including compound geotechnological cloth, compound geotechnological cloth bottom is provided with the non-woven fabrics layer, be provided with the bentonite granule jointly between compound geotechnological cloth and the non-woven fabrics layer, non-woven fabrics layer bottom is provided with the non-woven fabrics film.
Preferably, the composite geotextile comprises two polyester fiber layers, and a nylon film is fixedly connected between the two polyester fiber layers, so that the tensile strength of the waterproof blanket is improved, and the water blocking capability of the waterproof blanket is improved.
Preferably, the composite geotextile has a thickness of four millimeters, and is thinner than the existing geotextile, so that the thickness of the waterproof blanket is reduced.
Preferably, the thickness of the non-woven fabric layer is two millimeters, the structural strength is proper, and the bentonite inside can be conveniently fixed by combining the composite geotextile.
Preferably, the composite geotextile is connected with the non-woven fabric layer through needling, and the composite geotextile can be automatically separated from the non-woven fabric layer when the bentonite particles in the composite geotextile absorb water and expand.
Preferably, the non-woven fabric film and the non-woven fabric layer are connected in a melting mode, so that bentonite particles can be prevented from leaking from the thinner non-woven fabric layer, and the waterproof performance of the waterproof blanket is improved.
The beneficial effects of the utility model are as follows:
1. the utility model discloses a mutually support between non-woven fabrics layer and the non-woven fabrics film, through the non-woven fabrics heating with the bottom when producing, form the one deck film, when using, not only can effectively prevent that the bentonite of the inside from dropping, also can play better water-proof effects in addition, the better use of the user of being convenient for.
2. The utility model discloses be provided with the nylon film, through be provided with the nylon film in compound geotechnological cloth, the effectual waterproof ability who improves waterproof blanket has increased waterproof blanket's tensile strength simultaneously, makes it not fragile.
3. The utility model discloses be provided with compound geotechnological cloth and non-woven fabrics layer, be in the same place geotechnological cloth and non-woven fabrics link together through the acupuncture technique, when the bentonite granule of inside water swelling, geotechnological cloth and non-woven fabrics can autosegregation, and the user of being convenient for uses.
