Abstract
The utility model relates to a composite waterproof blanket which belongs to the geotechnique technical field. In the composite waterproof blanket, sodium bentonite and fibers are arranged between two layers of geotextile, wherein a layer of photocureable adhesive is coated outside the lower layer of the geotextile, thereby forming a four-layer waterproof blanket. The product stripping performance is excellent, and the relative fluctuation is reduced and is far higher than the standard line; and the curing speed of the photocureable adhesive is high, and the product output of equipment operating at high speed is not restricted.
Description
Technical field
The utility model belongs to the geotechnics field, is specifically related to a kind of waterproof blanket.
Background technology
The sodium bentonite waterproof blanket is popularized in the application of earthwork engineering gradually as this a kind of nonvolatil environment-friendly impervious material.Sodium bentonite imbibition under the restriction of two-layer geotextiles forms fine and close gelatinous layer.Because the brute force of adhering between the two-layer nonwoven there are differences, so the restricted bad control to expanding, fissility is poor, and in order to remedy this defective, giving birth to manufacturer often needs to pay a high price.
Summary of the invention
The purpose of this utility model provides a kind of composite water-proof blanket, with problems such as solution prior art fissility differences.
The utility model mainly is made up of geotextiles, sodium bentonite, solving the technical scheme that its problem adopts is between two-layer geotextiles sodium bentonite to be set, fiber places between the two-layer geotextiles, and the one deck of lower floor's geotextiles outside coating therein optic-solidified adhesive constitutes four layers of waterproof blanket.
Adopt good effect of the present utility model to be:
1, the stripping performance excellence of waterproof blanket product, fluctuation reduces relatively, and far above normal line;
2, the curing rate of optic-solidified adhesive is fast, can not produce the production capacity restriction to the equipment of high-speed cruising.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is the utility model structural representation;
1 geotextiles, 2 sodium bentonites, 3 optic-solidified adhesives, 4 fibers among the figure.
The specific embodiment
As shown in the figure: between two-layer geotechnological 1 cloth, add sodium bentonite 2, upper and lower layer geotextiles 1 adopts nonwoven and woven cloth respectively, fiber 4 places between the two-layer geotextiles, smear optic-solidified adhesive 3 at lower floor's geotextiles 1 outer surface, optic-solidified adhesive 3 adopts light-sensitive emulsion, and light-sensitive emulsion is under the lucifuge environment, after accepting the 360mm UV-irradiation, solidify rapidly, form one deck light-curable glue film, constitute four layers of waterproof blanket.
Claims (1)
1. composite water-proof blanket, mainly be made up of geotextiles, sodium bentonite, it is characterized in that between two-layer geotextiles sodium bentonite being set, fiber places between the two-layer geotextiles, the one deck of lower floor's geotextiles outside coating therein optic-solidified adhesive constitutes four layers of waterproof blanket.
