Abstract

The utility model discloses a kind of bentonite waterproof blanket, it is respectively upper geotextile layer from up to down, bentonite bed, bottom geotextile layer, isolation film, the upper surface of wherein upper geotextile layer is cross bulge-structure, plastics wire ring is bonded between upper geotextile layer and lower geotextile layer, plastics wire ring is embedded in bentonite bed.A kind of waterproof blanket for providing bentonite bed and being inlaid with plastics wire ring of the utility model, solves the technical issues of bentonite bed bentonite flowing, more traditional needling process is simpler, swelling soil thickness can be increased, geotextile layer is bulge-structure, increases friction, and application range is wider.

Description

A kind of bentonite waterproof blanket

Technical field

The utility model belongs to waterproof blanket field, and in particular to a kind of bentonite waterproof blanket.

Background technology

Swelling waterproof blanket is one kind dedicated for artificial lake's water scenery, refuse landfill, underground garage, roof garden, water The geosynthetics of the antiseeps such as pond, oil depot and chemicals stockyard, it is to be filled in spy by the sodium bentonite of high-expansion Between the composite earthwork cloth and non-woven fabrics of system, the bentonite anti-leakage pad made of needle point method can form many small fibre spaces, It is bentonite clay particle to flow as a direction, forms uniformly highdensity gluey waterproof layer when meeting water in pad, effectively Prevent the leakage of water.But needle point method complex process, and bentonite bed thickness is restricted so that and waterproof effect is limited, passes The Geotextile that the waterproof blanket of system uses is flat, and friction is small, is easy to slide when being laid with vertical metope.

Utility model content

Purpose of utility model：In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of bentonite Layer is inlaid with the waterproof blanket of plastics wire ring, solves bentonite bed bentonite and is flowed to a direction, the bad skill of waterproof effect Art problem, geotextile layer are bulge-structure, increase friction, and application range is wider.

Technical solution：In order to realize that above-mentioned purpose of utility model, the technical solution adopted in the utility model are as follows：

A kind of bentonite waterproof blanket is respectively to go up geotextile layer from up to down, bentonite bed, lower geotextile layer, isolation film, The upper surface of wherein upper geotextile layer is cross bulge-structure, and plastic wire is bonded between upper geotextile layer and lower geotextile layer Circle, plastics wire ring are embedded in bentonite bed.

Preferably, plastics wire ring is in cross interlaced arrangement.

Preferably, upper geotextile layer and lower geotextile layer are made of glass warp knit composite earthwork cloth.

Preferably, bentonite bed is made of sodium bentonite.

Preferably, isolation film is HDPE films, metal is coated on HDPE films.

Advantageous effect：Compared with prior art, the utility model has the following advantages：

Plastics wire ring is bonded between upper geotextile layer and lower geotextile layer, plastics wire ring is embedded in bentonite bed, keeps away Exempted from it is bentonitic flowed to direction, compared with traditional needle point method, technique is simpler, and bentonite bed thickness can increase, Improve waterproof effect；Geotextile layer surface is cross bulge-structure, more friction, is suitable for different occasions, especially suitable With the laying of vertical plane so that the application range of waterproof blanket is wider；It is coated with metal on isolation HDPE films, can effectively be prevented Shine, avoid waterproof blanket in transport and storage cannot long-time exposure the problem of.

Description of the drawings

Fig. 2 is the sectional view in the directions Figure 1A-A.

Fig. 3 is Fig. 1 vertical views.

Specific implementation mode

In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, embodiment is with the utility model skill Implemented under premised on art scheme, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this practicality Novel range.

As shown in Figure 1, Figure 2 and Figure 3, a kind of bentonite waterproof blanket is respectively upper geotextile layer 1, bentonite from up to down Layer 2, lower geotextile layer 3, isolation film 4, wherein the upper surface of upper geotextile layer 1 is cross bulge-structure, 1 He of upper geotextile layer Plastics wire ring 5 is bonded between lower geotextile layer 3, plastics wire ring 5 is embedded in bentonite bed 2.Plastics wire ring 5 is sprayed using plastics Silk technique, plastics wire ring 5 are in cross interlaced arrangement, and the density of plastics modeling circle 5 should not be too large, sparse, in bentonite bed 2 Bentonitic sliding can be prevented by being inlaid with plastics wire ring 5, and bentonite is made to recess sliding when avoiding paved surface unevenness Bad at waterproof effect, the cross convex design on 1 surface of upper geotextile layer can increase the friction of waterproof blanket and paved surface, especially It is the more aspect when vertical metope is laid with, practical.

Upper geotextile layer 1 and lower geotextile layer 3 are glass warp knit composite earthwork cloth, and glass warp knit composite earthwork cloth is a kind of By glass fibre (or synthetic fibers) be reinforcing material, by with it is chopped fiber needle-punched it is non-woven fabric compounded made of new geomaterial. It is different from general geotextiles, not only has the characteristics of high-tensile, low elongation, and have the property of needle fabric concurrently Energy.Therefore warp knit composite earthwork cloth is that one kind can be used for reinforcement enhancing, isolating and protecting, and has three-dimensional whole normal direction and level There are preferable polywater, the effect of different water.

Bentonite bed 2 is sodium bentonite, Na-bentonite soil series natural inorganic material, even across for a long time or around Environment changes, and aging or corrosion phenomenon will not occur, when sodium bentonite meets water, with 20-28 times of expansion energy Power.

Isolation film 4 is HDPE films, and metal is coated on HDPE films, can be effectively sun-proof, avoids waterproof blanket and exists Transport and storage in cannot long-time exposure the problem of.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the scope of protection of the utility model.
