Application of geotextile in river slope protection

With the development of social economy, environmental protection has attracted more and more attention. In terms of environmental protection, the construction of river slope protection is very important. In the construction of river slope protection, the use of Geotextiles has gradually become a trend. This article will explain the reasons for using geotextiles for river slope protection from the following aspects.

Definition and characteristics of geotextile

Geotextile is a Non-woven fabric composed of polyester fiber or polyester fiber and plastic film. It has the characteristics of light weight, high strength, corrosion resistance, anti-aging, and good anti-seepage performance. In river slope protection projects, geotextiles can perform functions such as reinforcement, drainage, filtration, and protection.

Benefits of using geotextiles for river slope protection

1. Reinforcement function:

Because geotextiles have good tensile strength and toughness, they can form a protective layer on the surface of the river slope protection, effectively improving the stability of the slope protection and preventing collapses and landslides.

2. Filtering effect:

The filtration effect of geotextile is mainly reflected in preventing water and soil erosion. In the construction of river slope protection, geotextiles can be laid on both upstream and downstream banks to effectively intercept sediment in the water flow, reduce soil erosion, and protect the ecological environment of the river bank.

3. Drainage function:

Geotextiles have good drainage properties and can effectively drain water under the slope protection, reduce the impact of water pressure on the slope protection, and ensure the stability of the slope protection.

4. Protective effect:

Because geotextile has good corrosion resistance, it can effectively prevent the water flow in the river from eroding and scouring the slope protection, thereby protecting the structural stability and integrity of the slope protection.

Application of geotextile in river slope protection construction

In the construction of river slope protection, geotextiles are widely used. Generally speaking, river slope protection requires the following steps: foundation clearing, filling, rolling, drainage, vegetation planting, etc. In these steps, the application of geotextiles is indispensable.

1. Clear base:

Before the construction of the slope protection, the river bank needs to be cleared and leveled. In this process, geotextiles can protect the riverbank from damage by construction machinery and human factors.

2. Filling:

During the river slope protection and filling process, geotextiles can effectively prevent water and soil erosion and protect the river bank ecological environment. At the same time, geotextiles can also play a role in drainage, effectively reducing the impact of water pressure on the fill body.

3. Crush:

During the rolling process of river slope protection, geotextile can play a protective role and effectively prevent water flow from eroding and scouring the filling body. At the same time, the geotextile can also play a filtering role to separate the moisture and sediment in the filling body.

4. Drainage:

In terms of river slope protection and drainage, geotextiles can have a good drainage effect. Laying geotextiles in the filling body can effectively drain the water below and reduce the impact of water pressure on the filling body.

5. Vegetation planting:

In terms of planting vegetation for river slope protection, geotextiles can play a protective role. Laying geotextile on the surface of the filling body can effectively prevent water flow from scouring and eroding vegetation, and protect the stability and integrity of vegetation.

In short, the use of geotextiles has become a trend in the construction of river slope protection. It can not only improve the stability, drainage and vegetation coverage of slope protection, but also play a protective and filtering role. In future river slope protection construction, with the continuous improvement of environmental protection awareness and the continuous development of application technology, it is believed that the use of geotextiles will become more widespread and popular.
