A comprehensive analysis of geotextile ( in English)

土工布是土工合成材料大家族中的一员，大量用于公路、铁路、水利、大型建筑、电厂灰坝建设、有色金属尾矿处理、环保工程、水土保持等方面。应用工程：水利工程建设：海堤、江堤、湖堤达标工程；水库加固工程；滩涂围垦工程；防汛抢险。

Geotextiles geosynthetics is a member of the large family of widely used in highway, railway, water conservancy, construction, large, power plant ash dam construction, non-ferrous metal tailings disposal, environmental engineering, soil and water conservation. Application: the construction of water conservancy project: the seawall, dyke, Lake embankment project target; reservoir reinforcement engineering; reclamation project; flood control.

土工布原料是涤纶、晴纶、锦纶等高分子聚合物的合成纤维.按照制造方法分为:有纺土工布和无纺土工布两种类型.一般工程主要是使用的无纺土工布.土工布

具有防渗、反滤、排水、隔离、加固、防护、密封等多种功能,它与常规的砌石及砼材料防渗效果相比,具有投资低,施工工艺简单,工期短,防渗效果好,渠道有效利用系数高等优点,如咸阳市渭河堤防工程施工中,有针对性地对两段河堤,分别采用土工布与传统方法施工.经过两种施工方案进行比较,使用土工布修筑的500m河堤,共投资20.55万元,投劳1.56万个工日.而用传统方案修筑同样长度河堤,则需投资27.37万元,投劳1.84万个工日,两方案相比较,运用土工布新材料后,投资、投劳可分别降低25%和15%.宝鸡峡灌区东四支渠节水改造、北干渠72km抢险工程中成功使用了这种新型材料,不仅取得了明显的防渗效果,而且降低投资,缩短了工期,可谓一举多得.土工布具有很好的防渗隔离作用.

The geotextile material is synthetic fiber polyester, acrylic, nylon and other high molecular polymer. According to the manufacturing methods are divided into: there are two types of nonwoven geotextiles and geotextile. General engineering is the use of nonwoven geotextile, geotextile has cut-off, filtration, drainage, isolation, and multifunctional solid, protection, sealing, compared with the masonry and concrete anti-seepage effect of conventional, has the advantages of low investment, simple construction process, short construction period, good anti-seepage effect, channel advantages of effective utilization coefficient, such as Xianyang Weihe dike engineering, the two section of riverbank, respectively geotextiles and traditional methods of construction. After two kinds of construction schemes are compared, the use of geotextile built the 500m River, a total investment of 205500 yuan, 15600 man-days labor. While the traditional scheme to build the same length of embankments, need to invest 273700 yuan, labor 18400 work day, two schemes compared, using geotextile new materials, investment, labor is the new

material success using reduced 25% and 15%. of Baoji Gorge Irrigation District East Branch Canal water-saving transformation, respectively, the north channel 72km emergency project, not only achieved obvious seepage prevention effect, and reduce the investment, shorten the construction period, Can kill. Geotextile has cutoff effect very well.

土工布产品特点.

Geotextile product features.

1、强力高,由于使用塑料扁丝,在干湿状态下都能保持充分的强力和伸长.

1, high strength, due to the use of plastic tape, can maintain sufficient strength and elongation in dry and wet conditions.

2、耐腐蚀,在不同的酸碱度的泥土及水中能长久地耐腐蚀.

2, corrosion resistance, long corrosion in soil and water in different pH value.

3、透水性好在扁丝间有空隙,故有良好的渗水性能.

3, good water permeability, a void in the flat, so the seepage performance is good.

4、抗微生物性好对微生物、虫蛀均不受损害.

4, microbial resistance were not affected by the damage to the good microbes, insects.

5、施工方便,由于材质轻、柔,故运送、铺设、施工方便.

5, construction is convenient, because the material is light, soft, so transporting, laying, construction is convenient.

6、规格齐全: 幅宽可达6米.是目前国内最宽产品,单位面积质

量:100-600g/㎡.

6, complete specifications: width up to 6 meters, is currently the most wide products, mass per unit area: 100-600g/ square meters.
