curing Geotextile Geotextiles, also known as geotextiles, are permeable geosynthetics made of synthetic fibers through needle punching or weaving. The finished product is cloth, generally 4-6 meters wide and 50-100 meters long. Geotextiles are divided into woven geotextiles and non-woven geotextiles.
The curing geotextile has good air permeability and water permeability, allowing water to pass through, thus effectively retaining sand loss.
With good water conductivity, it can form a drainage channel inside the soil mass to drain the excess liquid and gas in the soil mass structure.
The curing geotextile can enhance the tensile strength and deformation resistance of the soil, enhance the stability of the building structure, and improve the quality of the soil.
Effectively diffuse, transmit or decompose the concentrated stress to prevent the soil from being damaged by external forces.
Prevent upper and lower layers sand Mixed soil and concrete.
The mesh is not easy to be blocked - the mesh structure formed by the preparation of amorphous fiber has strain and mobility.
Corrosion resistance - made of polypropylene fiber or polyester fiber, acid and alkali resistant, non corrosive, and non moth eaten
Simple construction - light weight, convenient use, simple construction
Geotextiles have the functions of filtering, isolation, reinforcement and protection, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance.
The curing geotextile is used for;
(1) In highway (including temporary road) * * *, embankment, earth rock dam, airport, sports ground and other projects, it is used to strengthen soft foundation, and also plays the role of isolation and filtering. Geotextiles are placed on the bank slopes of rivers, lakes and seas, which can also prevent flowing water from washing.
(2) It is used as reinforcement in the backfilling of retaining wall or as the panel for anchoring the retaining wall. Build wrapped retaining walls or abutments.
(3) Reinforce the flexible pavement, repair the cracks on the road, and prevent the pavement from reflecting cracks.
(4) Increase the stability of gravel slope and reinforced soil to prevent water and soil loss and frost damage of soil at low temperature.
(5) The isolation layer between ballast and subgrade, or between subgrade and soft foundation.
(6) Xs The isolation layer between artificial fill, rockfill or material yard and foundation, and the isolation between different frozen soil layers. It plays the role of anti filtration and reinforcement.
(7) The filter layer on the upstream dam surface at the initial stage of the ash storage dam or tailings dam, and the retaining wall backfill drainage system Filter layer of.
(8) The filter layer around the drainage pipe or gravel drainage ditch.
The curing geotextile is a little bit;
1 Good physical and mechanical properties
The working environment of geotextile is harsh, and in many cases it is soaked in water or laid in soil with high humidity, so it must have good hydrolysis resistance and wet mechanical properties.
2. UV radiation resistance, hydrolysis resistance, high and low temperature resistance
Xs geotextile should be exposed to sunlight, so it should have corresponding ultraviolet resistance; The geotextile shall adapt to asphalt The melting point is required to be high when the materials are in contact with each other.
3 Chemical resistance, corrosion resistance and mildew resistance
Water and soil are very different, some are alkaline, some are acidic, some contain more salt, and some contain various elements, so they must have chemical stability.
4. The curing geotextile has good water permeability
