(13) artificial fill and drainage Ground Stadium Foundation. East Lingwu III. 42,728,026 Ran. (14) road (including temporary roads) railway, embankment, dam, airports, stadiums and other projects to strengthen the soft ground. Fourth, the function of an isolation that is for the use of geotextile materials with different physical properties (particle size distribution, consistency and density, etc.) (such as soil and sand, sand and gravel, soil and concrete, etc.) isolation . So between two or more materials is not lost, not mixed, maintaining the overall structure and function of materials, so that the load bearing capacity of structures strengthened. 2. When water flows into the filter by the fine soil coarse soil, the use of geotextile good air permeability and water permeability, water flow through. And effective closure of the soil particles, sand, small stones, so as to maintain a stable water and soil engineering. 3, drainage geotextile is good water permeable material, it can form drainage channels in the soil structure, the internal structure of the soil of excess fluid and gas excluded. 4, reinforced the use of geotextile reinforced soil tensile strength and resistance to deformation, enhance the stability of the building structure in order to improve soil quality. 5, protective effective stress will focus on proliferation, transfer, or decomposition, to prevent soil damage by external force while. 6, closed geotextile and other materials (asphalt, plastic film) with the formation of impermeable barrier in the soil. (Mainly for road resurfacing, patching, etc.). V. Application fields WATER: seawalls, river bank, Hudi standard works; reservoir reinforcement project; reclamation project; flood control. Road and rail project: Soft Foundation Treatment; slope protection; pavement structure layer anti-reflective cracks; drainage system; greenbelt. Electrical engineering: basic engineering of nuclear power plants; thermal power ash dam project; Hydropower Project. 6, the main characteristics of polyester filament non-woven geotextile has excellent heat resistance, light resistance. Even in the environment of nearly 20 ℃ in short-term exposure, its performance is almost unchanged. After a lot of trial and proved, polyester filament non-woven geotextile has a variety of natural soil, water and microbial long-term corrosion resistance. The products are mainly used in the following characteristics: 1, can play a permanent role in isolation; long-term isolation layer of soil composition and properties of different components and to prevent mixed; with frost resistance and load requirements necessary for construction. 2, with good filtration properties and corrosion resistance; moisture can penetrate in all directions, not accumulate pressure. While preventing soil erosion, in favor of stability and corrosion resistance. 3, with reliable drainage performance; the bulkiness of its structure, can effectively control surface drainage geotechnical engineering. 4, has a good protective properties; because of its good health puncture resistance, extensibility and fluffy, which can effectively protect the waterproof layer to prevent from potential mechanical damage. 5, with reinforced properties; bulkiness and high strength improved the overall stability of the project and increase its strength. Seven, the application of non-woven geotextile staple acupuncture geotextiles and geotextile filament spunbond process. Staple acupuncture geotextile is polyester, polypropylene or nylon staple fiber as raw material, and hair, flow management, lapping, acupuncture, acupuncture complex processing. It features a high-density, fluffy structure, corrosion, anti-aging, acid, water absorption and water permeability, high tensile strength, high resistance to deformation capacity. Frothing suitable for controlling road, slope protection, drainage and other projects in the protective layer, the wider application in the country. Such as the beach Liaohe Oilfield, mostly high soil moisture, high compressibility, low bearing capacity of soft plastic and plastic-like flow bore when the spring thaw period began paving, redistribution due to soil moisture changes, resulting in serious Frothing pavement. In view of this situation, Liaohe Oilfield design uses a four hundred domestic LHw polyester needle-punched nonwoven geotextile to combat road Frothing spring thaw of permafrost Embankment. This is done in the slag pavement under a single LHw 400 geotextiles as an isolating layer. Experimental results show that the geotextile has a significant role in isolation, can effectively control the road mud pumping and having reinforcing effect and stress diffusion, greatly improving the stability marshy embankment. Another example Daguangba Project dam of a total length of 5842 m, 2792 m dam where the left bank, right bank dam 2,339 meters, in the dam upstream slope protection using acupuncture nonwovens and bouldering method of combining slope. After two years of construction slope it shows that the method has anti storm erosion, reduce storm run-up and the ability to adapt to strong deformation and other advantages. Another example is an investment of 800 million yuan, Shandong Yellow River to Qingdao project, selected non-woven production plant in Shandong Changyi staple acupuncture non-woven geotextile for drainage surface protection layer, engineering design with a cloth amount is 90 million square meters, Drainage surface construction method is laying a layer of plastic film over the holes and geotextiles, and then line up the concrete slab to prevent drainage water with underground leakage, while filament geotextile major protective effect to prevent plastic sheeting being concrete Board destruction: In addition, staple acupuncture geotextile is also applicable safety ditch river dam fall as drainage facilities, used in soft foundation treatment seawall, have received good technical effects and economic effects. Eight, the development trend of foreign applications for geotextile began in the early 1960s, the United States is the largest country of the world consumption of geotextiles, which in recent years in the early 1990s, the amount of its annual consumption of just more than 300 million m2, to reach 700 million m2. Europe and Japan have also been rapid development of geotextiles, geotextile annual consumption in Europe in recent years are also 400 million m2, of which spunbond non-woven cloth accounted for about 60% of non-woven geotextiles; Japan in the mid-1990s After application of the geotextile has a significant growth. Japanese non-woven geotextile to spunbonding largest amount, accounting for about 60% of the non-woven geotextile fabric total, and mainly PET spunbond fabrics. Our geotextiles started in the early 1980s, but the amount was very small, only experimental applications. Until 1998 flood caused by the government's attention, the construction sector to be included on the application of geotextiles to design specifications go, and development of the relevant national standards, geotextile really get attention and development. Currently the amount of geotextile has more than 300 million m2, nonwoven geotextiles accounted for about 40% share of the total amount. Our civil engineering construction has a huge potential market, its potential never lower than the amount of US 7 to 800 million m2. Experts estimated that China geotextile will continue to double-digit growth in the next 15 years, faster growth is PET filament spunbond geotextile. Ng zero three. Wantonly, Ba II, Ba II, one qi qi. East Wyatt. In the "fifth" up "Eleventh Five Year Plan" period, China's planning huge investments in various projects in water conservancy, electricity, transportation, environmental protection, harnessing of rivers, etc., including water conservancy construction, water diversion project, electricity investment, road and rail construction, environmental projects, as well as ports, airports, waste disposal, rivers and lakes governance, sand and so on project investment amounted to tens of thousands of yuan. China in the next 10 years or more, there will be more to the construction of infrastructure projects, the demand for geotextiles will also be more and more, China will become the world's largest marketing geosynthetics market.
