Application: the construction of water conservancy project: the seawall, dyke, Lake embankment project target; reservoir reinforcement engineering; reclamatio
3、n 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
4、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. Accord
5、ing 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
6、 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, respe
7、ctively 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
8、 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,
9、 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 main
10、tain 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
11、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
12、/ . 6, complete specifications: width up to 6 meters, is currently the most wide products, mass per unit area: 100-600g/ square meters. 当前土工布的用途 : Use of the geotextiles: 1、水利工程 : 海堤、江堤、湖堤达标工程; 水库加固工程 ; 围垦工程 ; 防汛抢 险. 1, water conservancy project: the seawall, dyke, Lake embankment project target; re

15、割（钩刀），如在场地内切割，对其他材料须采 取特殊保护措施，以防由于切割土工布而对其造成不必要的损坏； Geotextiles used 1 geotextile can only knife ( hook ), such as cutting in the field, on other materials shall take special protective measures, to prevent the cutting of geotextile and its cause unnecessary damage; 2. 在铺设土工布的同时， 必须采取一切必要措施， 以防止对下面一
16、层材料造成破 坏； 2 in the laying of the geotextile and at the same time, we must take all necessary measures to prevent damage, below a layer of material; 3. 在铺设土工布时，必须注意不要让石头、 大量尘土或水分等有可能破坏土工布、 有可能阻塞排水渠或过滤网、 或有可能给接下来的连接带来困难的物质进入土工 布或土工布的下面； 3 in the laying of the geotextile, must now pay attention not to
17、let the stone, a lot of dust or moisture may damage the geotextile, likely blocked drains or filter, or may bring difficulty to the next connection material into the geotextiles and geotextile; 4. 安装结束后， 对所有土工布表面进行目测以确定所有损坏的地主，作上标记并 进行修补，确定铺设表面没有可以造成损坏的外来物质，如断针等异物； 4 after completion of the installa
18、tion, all the geotextile surface was visually to identify all damage to the landlord, marked and repair, identify the laying surface can not cause foreign material damage, such as broken needle and other foreign bodies; 5. 土工布的连接必须遵循以下规定：正常情况下，坡面上不能有水平连接（连接 须沿坡面的轮廓不与其相交），除修补的地方以外。6. 如采用缝合，缝合线 须采用与土工
19、布材质相同或超过的材料，缝合线须为防化学紫外线的材持。缝合 线与土工布应有明显的色差，以便于检查。 5 geotextiles connection must comply with the following provisions: under normal circumstances, the slope can not be connected ( connected to be along the slope contour is not its intersection ), in addition to repair. 6 such as the use of suture, su
20、ture and geotextile material shall be used for the same or more than material, suture line must be chemical UV material holding. Suture line and geotextile should have clear off color, in order to check. 7. 安装时对缝合特别注意以确保没有泥土或砾石覆盖层中的砾石进入土工布中 间。 7 installation of suture special attention to ensure that no dirt or gravel layer of gravel into the geotextile intermediate.中兴土工布 !
