4 What is the Difference Between Woven and Non Woven Geotextile
Non woven and woven geotextiles are two types of geotechnical materials used in various civil engineering and construction applications. Although the two have similar uses, they have significant differences in manufacturing processes, structures, performance, and applications. On e of the main function of non woven Geotextile is to protect the Geomembrane, and the main function of woven Geotextile is to reinforce the foundation, etc. Here is the main differences:
4.1 Functions of Woven Geotextile
Woven geotextile is a material woven from polyester, polypropylene or other synthetic fibers that has high tensile strength and stiffness. It is commonly used in civil engineering and land management to reinforce and enhance the functionality of soil masses. The following are the reinforcement functions of Woven Geotextile:
4.1.1 Tensile strength
Woven Geotextile has high tensile strength and can resist the tensile force of the soil. When stress is applied to the soil, Woven Geotextile can disperse the tensile force over a larger area through its woven structure, thereby reducing the deformation and damage of the soil.
4.1.2 Spreading Loads
Due to the rigidity and strength of woven geotextile, it can be used to spread and transfer loads. In projects such as roads, railways and dams, Woven geotextile can be used as a reinforcing material to evenly distribute the load to a larger area and reduce the settlement and deformation of the soil.
4.1.3 Provide soil stability
Woven geotextile can be combined with the soil to increase the shear strength and anti-sliding stability of the soil. It can prevent the movement and dislocation of particles within the soil and improve the overall stability of the soil.
4.1.4 Control Soil Erosion
Woven geotextile can be used to control soil erosion. In places such as riverbanks, riverbeds and beaches, Woven geotextile can act as a protective layer to prevent soil erosion by currents and waves. It stabilizes the soil surface and slows water flow, preventing soil erosion and erosion.
Overall, woven geotextile is able to provide soil reinforcement and reinforcement through its high strength and rigidity, as well as its bonding with the soil. It is widely used in civil engineering to enhance soil stability, distribute loads and control soil erosion.
4.2 Functions of Non woven Geotextile
Non woven Geotextile plays an important role in protecting geomembrane. Geomembrane is an impermeable membrane used to prevent liquids or gases from penetrating into soil or other structures. Non woven geotextile can be used to protect geomembranes in the following ways:
4.2.1 Prevent Damage
Non woven geotextile can be used as a protective layer over the geomembrane to prevent external physical damage, such as sharp rocks or scratches from construction equipment. It provides a cushioning layer that absorbs external impacts, reducing stress on the geomembrane and the risk of damage.
4.2.2 Distributed loads
In some projects, such as the construction of roads or sidewalks, non-uniform foundation pressure may cause geomembrane to deform or be damaged. non woven geotextile can be used as a load-spreading layer, which evenly distributes loads and reduces concentrated stress on the geomembrane.
4.2.3 Prevent penetration
non woven Geotextile has a certain degree of water permeability and can be used to prevent groundwater or other liquids from penetrating underneath the geomembrane. It acts as a filter layer, blocking particulate matter from entering the geomembrane, while allowing moisture to flow through and maintain water balance.
4.2.4 Provide stability
Non woven geotextile can provide stability by increasing the friction between the geomembrane and the surrounding soil. It can bond with the soil to form a stable interface, preventing the Geomembrane from slipping or shifting.
In general, non woven geotextile plays an important role in protecting Geomembrane, providing physical protection, load distribution, anti-seepage and stability functions to ensure the normal operation and service life of geomembrane.
