Abstract
The present invention relates to the field of water-proofing material technology, which is characterized by that it utilizes the unique water-proofing characteristics of sodium base bentonite to obtain the water-proofing function. Between upper layer nonwoven geotextile and lower layer polypropylene fabric the sodium base bentonite is filled up, then said three structure layers are mutually connected together by utilizing composite process (needle punching, sewing-up or splicing). Said product has excellent water-proofing property, and its construction is simple and convenient, and it has no any environment pollution.
Description
This invention relates to the waterproofing materials technical field.Many shortcomings that can't overcome have in use appearred in all kinds of waterproofing materialss of using in the engineering at present.Simultaneously, modern project such as dam construction, municipal and environment-friendly engineering, highway tunnel engineering etc. are more and more higher to the requirement of waterproofing materials.This product is promptly developed according to this requirement.
This invention utilizes the sodium bentonite particular performances to reach water-proof function.Sodium bentonite has good caking property, dilatancy, colloid dispersiveness, behind the chance water hydration reaction takes place, and volume expansion 10-15 doubly forms the colloid diaphragm, does not almost have water permeability.Be natural inorganic thing mineral matter owing to sodium bentonite again,, the variation of chemical property can not take place also, thereby reach forever perfect waterproof effect so the aging or corrosion phenomenon that takes place for a long time can not occur because of the time.In addition, sodium bentonite also has the characteristic of self-healing, and any breakthrough all can heal because of bentonitic migration, remains the water-proof function of no seepage and no leakage.
The structure of this product comprises 3 layers: the upper strata is the needling non-woven geotextiles; The intermediate layer is the sodium bentonite layer, and this sodium bentonite can be powdery or graininess, can be dry state or hygrometric state; Lower floor is that polypropylene is weaved cotton cloth or the needling non-woven geotextiles.Combination process is fill sodium bentonite between upper strata non-woven geotextile and lower floor's polypropylene are weaved cotton cloth after, with needle point method or additive method (sew up or bonding) three layer construction is connected.Bentonite bed is a waterproofing course, and swell soil is generally selected sodium bentonite in powder or particle for use, consumption 4000 gram/square metre more than, concrete consumption can be determined according to instructions for use.Two-layer up and down geotextiles plays the protection swell soil, prevents the effect that swell soil runs off.Two-layer up and down geotextiles is acupuncture geotextiles, woven geotextile or other geotextiles, that compound mode is that acupuncture geotextiles and acupuncture geotextiles pin are pressed is compound, acupuncture geotextiles and woven geotextile pin pressure are compound etc., the acupuncture geotextiles generally select for use 220 the gram/square metre more than the terylene geotextiles, woven geotextile generally select for use 110 grams/square metre more than pp geo textiles, selection can be determined according to concrete instructions for use in the production.The main production flow process is that geotextiles unreels, stores up cloth, cloth, spraying, pin and presses (seeing accompanying drawing two) such as compound, product examination, rolling packings.
Sodium bentonite can be powdery or graininess, can be dry state or hygrometric state, to the not influence of product effect.Adopt graininess hygrometric state sodium bentonite, in production and transportation, can reduce dust and swell soil and run off.Generally selecting granularity for use is the sodium bentonite particle of 0.5-3 millimeter.Behind cloth, by the atomized water of atomization mechanism to sodium bentonite particle ejection, or glue, glue mixed liquor, spraying makes moist softening the cohering of swell soil, prevents to run off, and reduces dust in the manufacturing process.Spray amount is adjustable continuously.Consider the requirement of the multiple class of cloth and spraying, big quantity and high uniformity, can adopt above cloth and the atomization mechanism of a cover, carry out repeatedly cloth and spraying.
The present invention has waterproof, seepage control excellent performance, easy construction, production and use and does not have characteristics such as any environment pollution, is the novel environment friendly waterproofing materials.Can be widely used in the strict engineering of waterproof, seepage control, as many fields such as hydraulic engineering, road, airport, refuse landfill and municipal and environment-friendlies.
Claims (5)
- This invention relates to the waterproofing materials technical field, and its characteristics are:1. waterproof roll comprises three layer construction: the upper strata is the needling non-woven geotextiles, and the intermediate layer is a sodium bentonite, and lower floor is that polypropylene is weaved cotton cloth or the needling non-woven geotextiles.
- 2. waterproof roll is as the waterproof base-material with sodium bentonite.
- 3. the sodium bentonite as the waterproof base-material can be a powdery, also can be granular; Dry state can be, also hygrometric state can be.
- 4. two-layer up and down geotextiles plays the protection swell soil, prevents the effect that swell soil runs off.Acupuncture that two-layer up and down geotextiles compound mode is that needling non-woven geotextiles and the acupuncture of needling non-woven geotextiles are compound, needling non-woven geotextiles and polypropylene are weaved cotton cloth is compound etc.
- 5. waterproof roll is with needle point method or additive method (stitching or bonding) two-layer geotextiles and bentonite bed to be combined with each other.
