Description

Bentonite waterproof blanket

Technical Field

The utility model relates to a geotechnical field specifically is a waterproof blanket of bentonite.

Background

The swelling waterproof blanket is a special anti-seepage geosynthetic material for artificial lake waterscape, garbage landfill, underground garage, roof garden, pool, oil depot, chemical storage yard and the like. The existing similar products are made by filling high-expansibility sodium bentonite between special composite geotextile and non-woven fabric, and the bentonite anti-seepage pad made by a needle punching method can form a plurality of small fiber spaces, so that bentonite particles can not flow like a direction, and a uniform high-density colloidal waterproof layer is formed in the pad when meeting water, thereby effectively preventing water leakage. The bentonite has the characteristic of water swelling, when the calcium bentonite swells, the swelling is only about 3 times of the self volume, and when the sodium bentonite swells in the presence of water, the sodium bentonite absorbs water with five times of the self weight, and the volume of the sodium bentonite expands to more than 15-17 times of the original volume, so that the sodium bentonite is locked between two layers of geosynthetic materials to play the roles of protection and reinforcement, and the GCL has certain integral shear strength.

The existing waterproof blanket is basically two-layer, the waterproof blanket with the two-layer structure has short service life and poor seepage-proofing and water-blocking effects, cannot meet the use requirements after being used for a long time, and is easy to cause water seepage and water leakage; in addition, most of the existing bentonite anti-seepage mats are manufactured by adopting a needle punching method, but the needle punching method is complex in process, the thickness of a bentonite layer is limited, the waterproof effect is limited, the surface of geotextile adopted by the traditional waterproof blanket is flat, the friction is small, and the geotextile is easy to slide when being laid on a slope surface.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to foretell not enough, provide a water-proof effects is good, long service life, gliding bentonite waterproof blanket when can effectively preventing to lay the slope face.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a waterproof blanket of bentonite, including the layer that absorbs water, set up in the upper geotechnological cloth layer on the layer that absorbs water, set up in the lower floor's geotechnological cloth layer under the layer that absorbs water, set up in waterproof rete under the lower floor's geotechnological cloth layer and set up in skid resistant course under the waterproof rete.

Further, the layer that absorbs water includes upper geotechnological stratum reticulare, weaving geotechnological cloth layer and lower geotechnological stratum reticulare that from top to bottom sets gradually, go up geotechnological stratum reticulare with all fill in the lower geotechnological stratum reticulare has the bentonite granule.

Further, the waterproof membrane layer is a double-layer high-density polyethylene membrane layer.

Further, a metal ceramic composite coating is sprayed on the bottom surface of the waterproof membrane layer, and the anti-skid layer is bonded below the metal ceramic composite coating.

Further, the anti-slip layer comprises a glue layer sprayed below the metal ceramic composite coating and abrasive particles bonded on the glue layer.

Further, the diameter of the abrasive particles is not less than 0.5 mm.

The utility model has the advantages that:

in practical application, the upper geotextile layer, the water absorbing layer, the lower geotextile layer and the waterproof film layer which are sequentially arranged from top to bottom can effectively prevent seepage for a long time, and the waterproof effect is good; the friction force is increased through the anti-slip layer, so that the slip when the slope surface is paved is effectively prevented; the utility model discloses water-proof effects is good, and long service life can effectively prevent to lay the slip during the slope face.
