Description

Introduction

Non woven geotextile, in addition recounted as geotextile, is a kind of geotextile made from fiber factors with the aid of mechanical, chemical, or thermal techniques such as spinning, melting, or bonding. It is a kind of geosynthetic cloth with the following crucial characteristics and applications

1. Reinforcement and enhancement: Non woven geotextiles have actual tensile and electricity characteristics, and can play a function in reinforcement and enhancement in soil. It can be used to lengthen the shear strength, tensile strength, and compression resistance of soil, and enhance the steadiness and bearing conceivable of soil.

2. Protection and protection: Non woven geotextiles can be used to shield and protect soil or specific engineering structures. It can be used to stop soil erosion, riverbed erosion, soil slope protection, shoreline protection, etc. In addition, it can in addition be used to shield polluted groundwater from air air air pollution and play an crucial attribute in environmental restoration projects.

Applications

Widely used for reinforcement of railway subgrade, maintenance of highway pavement, sports hall, dam protection, isolation of hydraulic structures, tunneling, coastal mudflat, reclamation, environmental protection and other projects.

3.Filtering and Drainage: Non woven geotextiles have magnificent filtering performance, which can successfully give up soil particles and downstream particle transport, even as permitting water to ignore over through. It can be used to set up a filter layer in soil, enhance soil permeability and stability, to filter and take away suspended solids and impurities in the soil.

4.Isolation and Separation: Non woven geotextiles can be used to isolate and separate great soils or materials, stopping their mixing with every and each other. It can set up isolation layers between high-quality soil types. For example, in roadbed engineering, prone soil can be remoted from high-strength fill elements to quit mixing and agreement between the two.
