As a high-performance geosynthetics, woven geotextile plays a vital role in modern civil engineering, water conservancy engineering and marine engineering due to its unique physical properties and wide range of applications. This article will elaborate on the material properties, production process, main uses and professional applications of woven geotextiles in detail, in order to provide reference for technicians in related fields.Material properties of woven geotextilesWoven geotextiles mainly use polymer materials such as polypropylene (PP) or polyester (PET) to form a mesh structure through a precise weaving process. This structure is composed of horizontal and vertical fibers interwoven, which not only enhances the stability and tensile strength of the soil, but also has excellent water permeability and filtration properties. Compared with traditional geotextiles, woven geotextiles perform better in horizontal drainage, vacuum transmission and corrosion resistance.Production processThe production process of woven geotextiles includes multiple links such as raw material preparation, spinning, weaving, heat setting and finished product inspection. First, the polymer material is melted and made into filaments through a spinning machine; then, the filaments are interwoven into a mesh structure according to the predetermined warp and weft density using a weaving machine; finally, after heat setting treatment, the structure of the geotextile is more stable and its physical properties are enhanced. The entire production process strictly controls the quality to ensure that the finished product meets the requirements of various technical indicators.Main uses1. Land reclamationIn land reclamation projects, woven geotextiles are widely used in cofferdam construction, beach protection and seabed paving. Its high strength and corrosion resistance can effectively resist seawater erosion and scouring, and protect the newly created land from damage. At the same time, the permeability of woven geotextiles helps to maintain the ecological balance of the seabed and reduce the impact of engineering implementation on the marine environment.2. River regulationIn river regulation, woven geotextiles can be used to reinforce the bottom and slope of the river channel to prevent river channel scouring and erosion. Its mesh structure can enhance the stability and durability of the soil and reduce soil erosion. In addition, woven geotextiles can also play a filtering role, purify river water and protect the water ecological environment.3. Deepwater port cofferdamThe construction of deepwater port cofferdams has extremely high requirements for materials, which need to be able to withstand huge water pressure and wave impact. Woven geotextiles have become an ideal choice for deepwater port cofferdam construction due to their high strength, corrosion resistance and good water permeability. By laying woven geotextiles, the stability and durability of the cofferdam structure can be effectively enhanced to ensure the safe operation of port facilities.4. Silt solidificationIn silt solidification projects, woven geotextiles can be used to lay on the surface of silt to form a stable isolation layer. Its mesh structure can limit the movement of silt particles and improve the consolidation efficiency of silt. At the same time, the water permeability of woven geotextiles helps to remove excess water in the silt and accelerate the solidification process of the silt.5. Highway pavement coveringIn highway construction, woven geotextiles can be used as pavement covering layers to enhance the stability and bearing capacity of the roadbed. Its high strength and tensile properties can effectively prevent cracks, collapse and other diseases on the road surface, and extend the service life of the highway. In addition, woven geotextiles can also play a filtering and drainage role, keeping the roadbed dry and stable.Professional application cases1. Vacuum preloading process in port constructionIn port construction, woven geotextiles are often used in combination with vacuum preloading technology to reinforce soft soil foundations. Specific steps include laying woven geotextiles, laying drainage boards, laying filter pipes and testing equipment, laying sealing membranes and laying vacuum pumps. The water permeability and tensile properties of woven geotextiles play a key role in this process, ensuring the realization of vacuum preloading effects.2. Slope protection projects in river regulationIn river slope protection projects, woven geotextiles can be used to lay on the slope surface to form a protective layer. Its mesh structure can enhance the stability and anti-scouring ability of the soil body and prevent soil and water loss on the slope surface. At the same time, woven geotextiles can also play a filtering role, preventing soil particles from being lost with water and protecting the ecological environment of the river.As a high-performance geosynthetics, woven geotextile plays a vital role in modern civil engineering, water conservancy engineering and marine engineering. Its unique physical properties and wide range of applications make it the preferred material for many engineering projects. In the future, with the continuous advancement of technology and the continuous expansion of application fields, the application prospects of woven geotextile will be broader.
