Description

Introduction

Non woven geotextile (polyester geotextile, non-woven geotextile), in addition viewed as geotextile, is a permeable geosynthetic cloth made via needling or weaving artificial fibers. The completed product is in the structure of cloth, with a acquainted width of 4-6 meters and a dimension of 50-100m.

Geotextiles are divided into woven geotextiles and non-woven geotextiles. Geotextiles have pinnacle notch filtering, isolation, reinforcement and protection effects, excessive tensile strength, fabulous permeability, excessive temperature resistance, freezing resistance, growing historical resistance, and corrosion resistance.

Applications

In engineering initiatives such as highways (including transient roads), railways, embankments, earth and rock dams, airports, sports activities things to do matters to do fields, etc., it is used to pork up inclined foundations at the equal time as in addition taking area in a characteristic in isolation and filtration. Placing geotextiles on the economic group slopes of rivers, lakes, and seas can in addition stop water from being washed away.

Working Drawing

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

(2) Strengthen bendy pavement, restoration cracks on the road, and give up reflective cracks on the street surface.

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

(4) The isolation layer between avenue ballast and roadbed, or the isolation layer between roadbed and moderate foundation.

(5) The isolation layer between synthetic filling, rock filling, or material yard and foundation, as applicable as the isolation between specific frozen soil layers. Plays a attribute 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 computing gadget in the backfill soil of the defending wall.

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

(8) The filter layer of water wells, strain alleviation 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 indoors the earth dam, buried in the soil to dissipate pore water pressure.
