Geotextile storage, transportation and handling Geotextile rolls should be protected from damage before installation. Geotextiles should be stacked in a place where there is no accumulated water, the height of the stack should not exceed four rolls, and the identification piece of the roll can be seen. The geotextile must be covered with opaque materials to prevent UV aging. During the storage process, the integrity of the label and the integrity of the data should be maintained. The dimple drainage board manufacturers must be protected from damage during transportation, including from material storage to on-site transportation. Geotextiles that have been physically damaged must be repaired. Severely worn geotextiles cannot be used. Any geotextile in contact with leaking chemical reagents is not allowed to be used in this project.
Permeable geotextile laying method: use manual rolling; the cloth surface should be smooth, and the deformation allowance should be reserved as appropriate. The installation of filament or short dimple drainage board for sale is usually lapped, stitched and welded. The width of stitching and welding is usually 0.1 μm or more, and the overlap width is usually 0.2 M or more. Geotextiles that may be exposed for a long time should be welded or stitched.
The advantages of permeable geotextile:
To isolate, use polyester staple fiber needle-punched dimple drainage board factory price to isolate building materials (such as soil, sand, soil, and concrete) with different physical properties (particle size, distribution, consistency, and density). Two or more materials will not be lost or mixed, and maintain the overall structure and function of the material, thereby enhancing the load-bearing capacity of the structure.
Filtration, when water flows from the fine soil layer into the rough soil layer, polyester fiber is used to penetrate the geotextile, has good air permeability and water permeability, makes the water flow through, and effectively carries soil particles, fine sand and small. Stone, etc., to maintain the stability of water and soil engineering.
Drainage. Polyester staple fiber needle-punched geotextiles have good water-conducting properties and can form drainage channels in the soil to expel excess liquid and gas from the soil structure. Reinforcement, using polyester staple fiber needle-punched wholesale dimple drainage board to enhance the tensile strength and deformation resistance of the soil, enhance the stability of the building structure and improve the soil quality.
Protection, when water flows into the soil, it effectively spreads, transfers or decomposes the concentrated pressure to prevent the soil from being damaged by external forces, thereby protecting the soil. High tensile strength, good permeability, breathability, high temperature resistance, frost resistance, aging resistance, corrosion resistance, no insects.
