Now, geotextile can be said to be a very common geosynthetics in various engineering projects. After all, it is true that many engineering projects cannot do without it due to performance reasons. In particular, the filament geotextile in geotextile is widely used. The following is a brief introduction of the role of filament geotextile in flood control engineering.

Why filament geotextile can be used for flood control

What is flood control? Flood control means to avoid the occurrence of dangerous situations. Before the flood control, the commonly used materials were mainly earth materials, stone materials, hemp bags, etc. Soil and stone are the main materials for flood control and emergency rescue. Because of its wide range of sources and local materials, but also has many disadvantages, such as: too heavy weight, large volume, difficult to carry, and labor intensity, which increases the work volume.

The filament geotextile is different. It is mainly made of synthetic fibers by needling or knitting. It has the advantages of high strength, light weight, strong water permeability, waterproof and wear-resistant. Compared with stone materials and earth materials, it is better in flood control and emergency rescue, with simple construction technology and low price.

Five functions of filament geotextile in flood control engineering

We know that the performance of filament geotextile is very much. In a project, it often plays not a role, but a variety of properties at the same time. So what is the main role of filament geotextile in flood control engineering?

1. Drainage

The filament geotextile has the function of waterproof, it can cut off the seepage in the soil, and can discharge the seepage from the soil along the plane of the filament geotextile.

2. Isolation

Filament geotextile can separate different nature or different grades of earth and stone materials, so as to avoid doping each other and maintain the use of materials, so as to ensure the quality of construction.

3. Reinforcement

In flood control, the filament geotextile can take advantage of the high tensile strength of the geotextile, restrain the soil in the soil, reduce the deformation of the soil, and improve the stress of the soil.

4. Inverted filtration

In the process of flood control, the hydraulic function of filament geotextile can be used. When it is used to remove the seepage water, it can also prevent the geotextile particles, small stone particles and fine sand from being brought out.

5. Protection

In the process of flood control, filament geotextile can decompose the soil when it is scoured by water flow, so as to prevent the soil from being damaged by external forces.

The above is a brief summary of the five functions of the geotextile in flood control engineering by the geotextile manufacturers. In a word, there are many functions of the geotextile, which must be reasonably used in the actual engineering, so that a lot of resources can be saved.

Among many kinds of geotextiles, it can be said that the filament geotextile is widely used, of course, its wide application has nothing to do with its performance. As far as the present situation is concerned, filament geotextile has gradually replaced many traditional materials in many fields. So what are the properties and uses of filament geotextiles that make them so popular?

1. Tensile strength: under the same weight and specification, the tensile strength of filament geotextile is obviously better than that of other needle punched geotextiles.

2. High temperature resistance: the filament geotextile has good high temperature resistance. It can still maintain certain physical properties under the high temperature of 230 ℃.

3. Drainage: Although the filament geotextile is relatively thick, it has good air permeability and water permeability, and this performance can be maintained for several years.

4. Corrosion resistance: the filament geotextile is not only resistant to chemical corrosion, but also resistant to the decomposition of some microorganisms.

5. Ductility: filament geotextile has good ductility. It can adapt to irregular or uneven terrain.

As the so-called performance determines the use, there will be many uses of filament geotextile with so many properties, but few people know that filament geotextile can also be used in some harsh environments.

1. Filament geotextile can be used as reinforcement material, which is generally used for road or runway subgrade;

2. Filament geotextile can be used as reinforcement material, but also as subgrade can only be used in swamp area;

3. Filament geotextile can be used as thermal insulation material, mainly for frost and antifreeze;

4. Filament geotextiles can be used as drainage materials, such as reservoirs, mines and some high-rise buildings;

5. Filament geotextile can be used as anti crack material. For example, the old highway needs asphalt to be reinforced, but it is easy to crack. The use of filament geotextile can prevent the generation of cracks.

There are many uses of filament geotextile. In addition to those above, filament geotextile can also be used as filter material and anti scour material, etc. of course, its use is limited at present. However, many people are still studying whether the application of filament geotextile can be expanded. They believe that its application will be more and more extensive in the near future.
