一布一膜是由土工織物（長短絲針刺土工布，機織土工布，塑料編織布,膨潤土防水毯等）與高分子材料（HDPE膜，LDPE膜，EVA膜等）兩種以上的材料經(jīng)過壓延，熱熔復合而成的土工合成材料。 一布一膜有一定的變形量，對底墊層的凹凸缺產(chǎn)生的應力傳遞分散較快，應變能力較強。用土工織物代替粒材作為土工膜保護層，以保護土工膜防滲層不受損壞，降低墊層粒徑的級配要求，并能起排水作用。摩擦系數(shù)大，能防止覆蓋層的滑移，比單純HDPE薄膜，復合土工膜中的無紡布有較大的摩擦系數(shù)，復合土工膜可使坡比增大減少占地面積。撕裂，頂破，穿刺等力學強度較高。有一定的保溫作用，減少了土體凍脹對土工膜的破壞，從而減少土體變形。采用埋入式鋪設，有優(yōu)異的抗老化性能，減少了工程的維護保養(yǎng)。鋪設施工簡便，減少運輸量，降低工程造價，縮短了工期。 一布一膜因其良好的平面排水，優(yōu)良的防滲特性及抗拉，撕裂，頂破，穿刺等力學強度較高的特點可廣泛應用于
A film of a cloth is made of geotextile (length of wire nonwoven fabric, woven geotextile, plastic woven cloth, bentonite waterproof blanket etc.) and polymer materials (HDPE film, LDPE film, EVA film) more than two kinds of materials after rolling, geosynthetics hot melt compounded the. A cloth one film has a certain amount of deformation, the concave and convex and concave and convex and concave and convex lack of the bottom layer, the stress transfer is faster, and the strain ability is stronger. The use of geotechnical fabric instead of granular material as a protective layer of the soil, in order to protect the impervious layer from damage, reduce the size of the size of the size of the grading requirements, and can play the role of drainage. The friction coefficient, can prevent the sliding cover layer, than the pure HDPE film, non-woven composite geomembrane has large friction coefficient, composite geomembrane can make slope ratio increase and reduce the occupied area. Tear, bursting, puncture and other mechanical strength is higher. Have a role in insulation, reducing soil frost damage of geomembrane, thereby reducing the deformation of soil. The embedded laying, with excellent anti aging performance, reduce the maintenance of the project. Laying construction is simple, reduce transportation, reduce project cost, shorten the construction period. Because of its good surface drainage, excellent anti - seepage properties and tensile, tearing, breaking, puncture and other mechanical strength, high strength can be widely used in

6公路，高速公路，鐵路的路基，膨脹土和濕陷性黃土的防水層。施工要求 一布一膜的土工布作為土工膜的保護層，使保護防滲層不受損壞。為減少紫外線照射，增加抗老化性能，最好采用埋入法鋪設。施工中，首先要用料徑較小的砂土或粘土找平基面，然后再鋪設，鋪設時不要繃得太緊，兩端埋入土體部分呈波紋狀，最后在所鋪的一布一膜上用細砂或粘土鋪一層10cm左右過度層。砌上20-30cm塊石，作防沖保護層。施工時，應盡力避免石塊直接砸在上，最好是邊鋪膜邊進行保護層的施工。一布一膜與周邊結構物連接應采用膨脹螺栓和鋼板壓條錨固，連接部位要涂刷乳化瀝青（厚2mm）粘接，以防該處發(fā)生滲漏。施工接縫處理是一個關鍵工序，直接影響防滲效果。一般接縫方式有：①搭接：搭接寬度宜大于15cm；②熱焊：宜于稍厚的土工膜基材，焊縫搭接寬度不小于10CM.
6 highway, highway, railway subgrade, expansive soil and collapsible loess waterproof layer. The construction requires that the geotechnical cloth of a cloth is used as a protective layer of the geotechnical membrane to protect the impervious layer from being damaged. In order to reduce the ultraviolet radiation and increase the anti aging performance, it is better to use the embedded method. In the construction, material first to smaller size sand or clay leveling base, then laying, laying not stretched too tightly, both ends embedded in soil section corrugated, finally in a film a cloth shop with fine sand or clay layer about 10cm transition layer. 20-30cm block of stone, for the protection of the protective layer. When construction, should try to avoid the stones directly on the top, it is best to protect the edge of the film side of the construction of the protective layer. A cloth of a film and the surrounding structures shall be connected with the expansion bolt and steel strip anchor, connecting parts to daubing emulsified asphalt (thick 2mm) bonding, to prevent the occurrence of leakage. Construction joint treatment is a key process, which directly affects the seepage control effect. The general methods are: 1: lap joint lap width should be greater than 15cm; heat welding: geomembrane material is thicker, the lap width not less than 10CM.
