Description
Technical field
The utility model relates to a kind of waterproof blanket, and specifically a kind of sodium-based bentonite waterproof carpet, belongs to waterproof blanket field.
Background technology
Swelling waterproof blanket is the geosynthetics of the antiseeps such as a kind of artificial lake's of being specifically designed to water scenery, refuse landfill, underground garage, roof garden, pond, oil depot and chemicals stockyard, it is to be filled between special composite earthwork cloth and nonwoven by the sodium bentonite of high-expansion, the bentonite anti-leakage pad made from needle point method can form many little fibre spaces, bentonite clay particle can not be flowed to a direction, while meeting water, in pad, form even highdensity gluey watertight composition, the seepage of effective anti-sealing.Current GCL is combined insecure with construction surface, easily comes off, and self-locking water poor performance, construction is complicated, not ageing-resistant.
Utility model content
In order to address the above problem, the utility model has designed a kind of sodium-based bentonite waterproof carpet, and product is combined with construction surface firmly, and difficult drop-off has self-locking water function, and bentonite bed is easily damaged, and construction is succinct, and the duration is short, and applicability is strong.
The technical solution of the utility model is:
A kind of sodium-based bentonite waterproof carpet, comprise base fabric, the both sides up and down of described base fabric are equipped with one deck bentonite bed and go up bentonite bed and lower bentonite bed, the outside of described bentonite bed is also provided with layer of non-woven fabric layer, the outside of going up bentonite bed is provided with nonwoven layer on, the outside of lower bentonite bed is provided with nonwoven layer, and the surface of described upper nonwoven layer is provided with a density polyethylene film with high layer, and the surface of described lower nonwoven layer is provided with a photocuring glue-line.Photocuring glue-line not only can improve waterproof effect, and can make product and construction surface sound construction, difficult drop-off.Because density polyethylene film with high is water-soluble film, after meeting water, dissolve and disappear immediately, can not become new penetrating passage, therefore there is anti-string water effect, with sodium bentonite acting in conjunction, further strengthen waterproof effect, water resistance is lasting simultaneously, and can automatic water locking, its bottom fabric layer has reinforcing, isolation, the effect such as ageing-resistant.
Wherein, described bentonite bed is sodium bentonite stratum granulosum or prehydration bentonite lamella, and wherein the lamellose waterproof effect of prehydration bentonite is better.
Described base fabric is to split any one in film flat filament polypropylene woven geotechnique layer of cloth, polypropylene woven cloth, PE woven cloth, polypropylene filament yarn woven fabric and polyester filament woven fabric, preferably splits film flat filament polypropylene woven geotechnique layer of cloth.Described lower nonwoven layer is any one in short fiber polypropylene acupuncture nonwoven geotechnique layer of cloth, polypropylene non-woven fabric or terylene short fiber nonwoven, preferably short fiber polypropylene acupuncture nonwoven geotechnique layer of cloth; Described upper nonwoven layer is soluble non-woven fabrics, can lock water conservation to bentonite bed, the destruction of anti-sealing to bentonite bed.Can be applicable to the waterproof project of the water quality environment that strong acid and strong base or other chemical substances corroded, play and resist strong acid and strong base or other chemical corrosivity materials to bentonite structural damage effect, and can be applied in the water quality environment of different erosions by the ratio that changes mixture in sodium bentonite composite bed, not only expand the range of application of GCL, also simplified the pretreatment link in complicated water quality environment waterproof project construction simultaneously, greatly reduce the construction period, saved cost of labor.
Further, described upper bentonite bed is fixed between upper nonwoven layer and base fabric by needling process; Described lower bentonite bed is fixed between lower nonwoven layer and base fabric by needling process.Thereby make between each layer, in conjunction with more firm, to there will not be lamination.The surface of being combined with construction surface arranges nonwoven, has improved the skid resistance of waterproof blanket, and can increase the peel strength of product, makes it go for more severe construction environment, is also applicable to smooth surface and the relatively large construction area of the gradient simultaneously.
Further, between described upper nonwoven layer and base fabric, be provided with by orthogonal geotechnological cloth in length and breadth and connect and compose a paliform structure, in described paliform structure, be filled with bentonite bed; Between described lower nonwoven layer and base fabric, be provided with by orthogonal geotechnological cloth in length and breadth and connect and compose a paliform structure, in described paliform structure, be filled with lower bentonite bed.Paliform structure is interlaced, makes to be filled in sodium bentonite particle stationarity in fence structure good, can not be moved, and makes the thin and thick of sodium-based bentonite waterproof carpet even, strengthens its water proofing property.
Further, the surface of described density polyethylene film with high layer is covered with metallocene thin layer by glue spraying mode, surface arranges metallocene geotechnique thin layer, strengthen the stability of waterproof blanket water resistance, greatly reduce the infiltration coefficient of waterproof blanket, reach dual waterproof effect, and can increase the punctured resistance of product, make it go for more severe construction environment, during opposing construction operation is laid and impurity in the backfill soil of the upper strata destructive power to material surface, guarantee the surface integrity of waterproof blanket.
The utility model can be applicable to water contamination type engineering waterproofing, there is self-locking water function, can prevent from going here and there water, after watertight composition breakage, moisture is still locked in breakage, even when concrete herein also exists defect to occur water penetration, also very easily maintenance also can thoroughly be repaired watertight composition, thereby make watertight composition again bring into play waterproof action, product waterproof property and the adaptability to constructing structure and malformation are improved, once construction, construction is succinct, and the duration is short, do not need special mounting equipment and process, save waterproof construction number of times and expense.
By using natural sodium bentonite to make to the utlity model has good environmental protection, advantage from water-retaining property, and by increase polypropylene non-woven fabric layer in natural sodium bentonite, make waterproof blanket increase intensive properties and durability, simple in structure, construct simple and direct, convenient and practically, be easy to apply.
The utility model has the advantage of: product is combined with construction surface firmly, difficult drop-off has self-locking water function, and bentonite bed is easily damaged, and construction is succinct, and the duration is short, and applicability is strong.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
