Description

Introduction

Non woven geotextile (polyester geotextile, non-woven geotextile), additionally regarded as geotextile, is a permeable geosynthetic cloth made through needling or weaving artificial fibers. The completed product is in the structure of cloth, with a familiar width of 4-6 meters and a size of 50-100m.

Geotextiles are divided into woven geotextiles and non-woven geotextiles. Geotextiles have top notch filtering, isolation, reinforcement and safety effects, excessive tensile strength, suitable permeability, excessive temperature resistance, freezing resistance, growing old resistance, and corrosion resistance.

Applications

In engineering initiatives such as highways (including transient roads), railways, embankments, earth and rock dams, airports, sports activities fields, etc., it is used to fortify susceptible foundations whilst additionally taking part in a position in isolation and filtration. Placing geotextiles on the bank slopes of rivers, lakes, and seas can additionally forestall water from being washed away.

Working Drawing

(1) Reinforcement in backfill of preserving partitions or used to anchor panels of holding walls. Build wrapped conserving partitions or abutments.

(2) Strengthen bendy pavement, restore cracks on the road, and stop reflective cracks on the street surface.

(3) Increase the balance of gravel slopes and bolstered soil to stop soil erosion and frost injury to soil at low temperatures.

(4) The isolation layer between street ballast and roadbed, or the isolation layer between roadbed and gentle foundation.

(5) The isolation layer between synthetic filling, rock filling, or fabric yard and foundation, as properly as the isolation between special frozen soil layers. Plays a function in filtration and reinforcement.

(6) The filter layer of the preliminary upstream dam floor of the ash storage dam or tailings dam, and the filter layer of the drainage machine in the backfill soil of the holding wall.

(7) Filter layer round drainage pipes or gravel drainage ditches.

(8) The filter layer of water wells, strain comfort wells, or inclined pipes in hydraulic engineering.

(9) The isolation layer of geotextiles between highways, airports, railway tracks, and synthetic stone piles and the foundation. Non woven geotextile (5 sheets)

(10) Vertical or horizontal drainage interior the earth dam, buried in the soil to dissipate pore water pressure.
