Polyester long fiber spunbond needle punched geotextile composite geotextile has been widely used in bottom facilities to establish boundaries, and has been gradually used in wider areas. Water conservancy dam and slope protection of the inverted filter, channel isolation, seepage control. geotextile mat three-dimensional used in water and soil conservation.

Isolation and seepage control of waste landfill, ash dam of thermal power plant and tailings dam of mine. 4. Soft foundation management of port project, reinforcement and drainage of beach dike, harbor port and breakwater

Road, railway, airport runway bottom isolation, anti filtration, drainage, earth slope, composite geotextile retaining wall and Pavement Reinforcement, drainage. Composite geotextile aquaculture (fish pond, shrimp pond lining and other water conservancy (such as seepage prevention, leakage stoppage, reinforcement, water ditch seepage prevention, vertical core wall, slope protection, etc.)

Environmental protection (such as life waste landfill, sewage treatment, toxic and hazardous materials treatment, dangerous goods stack, industrial waste, construction and blasting waste and other petrochemical (chemical plant, oil refinery, gas station oil storage tank seepage control, chemical reaction tank, sedimentation tank lining, secondary lining)

Garden (artificial lake, pond, pool bottom lining of composite geotextile golf course, slope protection, etc.); agriculture (anti-seepage of reservoir, drinking pond, impoundment pond, watering system); mining industry (anti-seepage of washing pond, heap leaching pond, ash yard, dissolution pond, sedimentation pond, storage yard, low lining of tailings, etc.)

Traffic facilities (bottom reinforcement of highway, seepage prevention of culvert) Municipal Engineering (subway, underground engineering of buildings and roof storage pond, seepage prevention of roof garden, lining of composite geotextile sewage pipeline

The waterproof geotextile liner of each heap leaching site is evaluated qualitatively. The heap leaching site is built on the top of each tailings pond, and its natural slope extends to the side of the tailings pond. The natural slope angle is 2H: 1V

The structure design of the heap leaching tank is as follows: the geomembrane is laid on the lower layer, the geomembrane is laid on the membrane, and the net is another layer of geomembrane. The maximum height of the ore heap is 60m. After the heap leaching ore is excavated, the samples of geomembrane and its joints are tested. The results of the survey are expressed, and the geomembrane and its joints are not listed

In the tunnel construction, the release layer shall be laid before the waterproof board is laid, and the unit weight of the release layer shall be no less than 400g / m2 geotextile; the release layer shall be fixed on the base surface with cement nails or expansion bolts and circular gasket matched with the waterproof board, and the fixed points shall be arranged in a quincunx shape, the constant spacing on the side wall shall be 80 ~ 100cm, and the constant spacing on the vault shall be 50cm

The inspection of waterproof geotextile is mainly divided into the inspection before and after use, so that the difference above is to ensure the normal use of geotechnical engineering, which kind of multiple guarantee may be said

Before the construction of geotextile laying, it is required to check the full and spliced parts of geotextile, and make signs for real-time repair. After the completion of geotextile laying, it is required to carry out oral and visual inspection on the geotextile laid every day, and make clear whether the geotextile can exist again.
