What effects can the geogrid manufacturer achieve by using woven geotextile.Geotextile is mainly used in railway subgrade construction, highway subgrade construction and application, basic application of all kinds of construction sites, earth retaining of dykes and dams, disappearance of retained sand and soil, application of waterproof roll materials for tunnels, application of urban green flower engineering, underground garage waterproofing, base materials of waterproof materials, etc., artificial lakes, ponds, anti-seepage and waterproof application, clay liner, and also can be used in basic concrete cushion.

Unique is the use of woven geotextile when the settlement is uneven due to geological instability. Woven needle punched geotextile has excellent water conductivity and strong tensile property. It can cause filtering and drainage effect in the fill, make the foundation soil not disappear, strengthen the structure of the building, and strengthen the foundation dike. The product is of good stability, aging resistance, strong resistance to splitting, flexibility, and no fear of mold. It is a new material of environmental protection.

The woven geotextile has the characteristics of good adaptability, easy splicing with the original slope, simple construction, economic cost, one-time forming, and underwater operation. The quality of the mold bag is the quality before the single layer is sewn. The tensile strength of the mold bag fabric is the index without reinforcement. The final molding of the mold bag needs to be manufactured according to the engineering design requirements. The engineering unit needs to submit the design drawing or sewing drawing and related dimensions.

Geotextile is made of high-strength industrial polypropylene, polyester, nylon and other combined fibers, with high original strength. After weaving, it becomes a discipline intersection structure, and its comprehensive bearing capacity is further increased. Durability: the characteristics of the combined chemical fiber of the woven geotextile are not easy to change, decompose and weathering. It can maintain its original characteristics permanently.

Corrosion resistance: the combined chemical fiber of woven geotextile usually has acid resistance, alkali resistance, moth resistance and mould resistance. Water property: woven fabric can effectively control its structural pores to achieve certain water permeability.

Geotextile composite geotextile uses plastic film as the base material for seepage prevention, and non-woven fabric composite material for seepage prevention. Its seepage prevention function mainly depends on the seepage prevention function of plastic film

At present, PVC and PE are the most important plastic film used for anti-seepage at home and abroad. They are a kind of polymer chemical flexible material with small proportion, strong extensiveness and high adaptability to deformation

The main mechanism is that the impermeability of the plastic film insulates the leakage channel of the earth dam, and it can withstand the water pressure and conform to the deformation of the dam body with its large tensile strength and extension rate

The abnormal service life of the composite geotextile is mainly determined by whether the plastic film can be used for seepage prevention and water separation. According to the national standard of the Soviet Union, the polyethylene film with stabilizer with thickness of 0.2m is used for hydraulic engineering

The service life of composite geotextile can be 40-50 years under the condition of water purification and 30-40 years under the condition of sewage. Therefore, the service life of composite geotextile is enough to meet the service life of dam seepage control conditions

In order to deal with the leakage weak surface and dam foundation leakage caused by several landslides, the impervious body such as bedrock curtain grouting, intersection surface grouting, backfill curtain of punching and grabbing well and high-pressure jet anti-seepage board wall are adopted in vertical anti-seepage

The upper inclined wall is covered with composite geotextile for seepage control, and the lower and vertical seepage control walls are adjacent to each other, up to the elevation of 358.0m (0.97M higher than the check flood level). See the design drawing for the overall position and quantities
