Abstract
The utility model discloses a needle punching film coating method sodium bentonite waterproof blanket, relating to the technical field of building waterproof blankets. The needle punching film coating method sodium bentonite waterproof blanket comprises an upper layer of woven cloth and a lower layer of non-woven geotechnical cloth, wherein sodium bentonite is filled between the upper layer of woven cloth and the lower layer of non-woven geotechnical cloth, the upper layer of woven cloth, the sodium bentonite and the lower layer of non-woven geotechnical cloth are fixedly connected in sequence through a needle punching technology from top to bottom, and a layer of HDPE (high-density polyethylene) thin film is arranged on the lower surface of the lower layer of non-woven geotechnical cloth. The needle punching film coating method sodium bentonite waterproof blanket not only has good waterproofness, but also has excellent striping performance, and is simple in structure, reasonable in arrangement, low in making cost, energy-saving, environment-friendly and long in service life.
Description
Technical field
The utility model relates to buildings waterproof blanket technical field, particularly a kind of acupuncture method with plastic film sodium bentonite 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.
The utility model content
The purpose of this utility model is at the defective of prior art and deficiency, and a kind of stripping performance excellence, thorn method with plastic film sodium bentonite waterproof blanket that water resistance is good are provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of acupuncture method with plastic film sodium bentonite waterproof blanket described in the utility model, comprise upper strata woven cloth and lower floor's non-woven geotextile, between described upper strata woven cloth and lower floor's non-woven geotextile, be filled with sodium bentonite, described upper strata woven cloth, sodium bentonite are from top to bottom fixedlyed connected by needling process successively with the lower floor non-woven geotextile, and are provided with one deck HDPE film at the lower surface of described lower floor non-woven geotextile.
Further, the density of described HDPE film is at 0.95～0.96kg/L.
After adopting said structure, the utility model beneficial effect is: a kind of acupuncture method with plastic film sodium bentonite waterproof blanket described in the utility model, between described upper strata woven cloth and lower floor's non-woven geotextile, be filled with sodium bentonite, and be provided with one deck HDPE film at the outer surface of described lower floor non-woven geotextile.When using the utility model, because the HDPE film has higher mechanical strength, also have fabulous moisture resistance and oil resistivity preferably simultaneously, and it is colourless, tasteless, nontoxic, therefore, make this waterproof blanket not only have good water proofing property, also have excellent stripping performance simultaneously.The utlity model has simple in structurely, advantages such as cost of manufacture is low, energy-conserving and environment-protective, long service life are set rationally.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Description of reference numerals:
1, upper strata woven cloth; 2, lower floor's non-woven geotextile; 3, sodium bentonite;
4, HDPE film.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of acupuncture method with plastic film sodium bentonite waterproof blanket described in the utility model, comprise upper strata woven cloth 1 and lower floor's non-woven geotextile 2, between described upper strata woven cloth 1 and lower floor's non-woven geotextile 2, be filled with sodium bentonite 3, need to prove, described sodium bentonite is natural sodium bentonite particle, aging reaction, good endurance can not take place; And can not cause any adverse effect to environment, and owing to sodium bentonite is limited between woven cloth and the non-woven geotextile, thereby make bentonite become orderly expansion from unordered, the imbibition result who continues allows bentonite bed self reach closely knit, thereby has waterproof action, its impervious hydrostatic pressing can reach more than the 1.0MPa, permeability 50-55cm/s, unit are bentonite quality 5kg/m2, described upper strata woven cloth 1, sodium bentonite 3 is from top to bottom fixedlyed connected by needling process successively with lower floor non-woven geotextile 2, and the lower surface at described lower floor non-woven geotextile 3 is provided with one deck HDPE film 4, because the HDPE film has higher mechanical strength, also have fabulous moisture resistance and oil resistivity preferably simultaneously, and colourless, tasteless, nontoxic, be environment-friendly materials, therefore adopt the film adhered ground of HDPE, have percentage elongation, tearing strength, impact strengths etc. are very high characteristics all, i.e. the stripping performance excellence.
The density of described HDPE film 4 is at 0.95～0.96kg/L, and its density makes the mechanical strength of HDPE film also strengthen, and then makes stripping performance more excellent.
With the utility model when the construction, only need with the waterproof blanket tiling on the ground, when domatic, be fixed with nail and packing ring, and overlap joint gets final product on request, not only good water-proof effect, also has excellent stripping performance, in addition, even after waterproof construction finishes, as the watertight composition breakage that meets accident, as long as simply repair at the position to breakage, just can regain perfect water resistance as before.In addition, this is simple in structure, reasonable in design, low cost of manufacture, energy-conserving and environment-protective, long service life.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
