Geotextile Slope Protection Has Better Protection Effect

Compared with bare slopes, the amount and content of geotextile slope protection are greatly reduced. Compared with bare slopes, the sediment under high quality filament nonwoven geotextile protection is reduced by more than 43%, and the geotextile structure protection effect is obvious.

The smaller the geotextile spacing, the smaller the amount of erosion, the better the protection effect; the erosion of the silt protection of the convex structure is 40% less than that of the non-convex structure, and the protective effect is better. The raised structure can slow down the flow rate of rainwater and intercept the loss of sediment, so as to achieve a better protective effect. In geotextile protection, filament nonwoven geotextile for sale can intercept sediment and reduce sediment erosion.

For different combinations of protection forms, considering the cost and protection effect, the best protection effect is to use a raised structure with a spacing of 20 cm.

Geotextile slope protection has a good protection effect. Geotextile is buried in the soil, covering a certain width of soil, which plays a role in preventing seepage and preventing soil erosion. When rainwater forms runoff on the slope, wholesale filament nonwoven geotextile can avoid or reduce the erosion of runoff on the slope soil, and maintain the stability of the slope after construction.

The indoor slope simulation device and rainfall device can well simulate the characteristics of the slope, adjust the angle and rainfall intensity, and realize the slope simulation with different slopes and rainfall intensity.

Geotextile Slope Protection Has Better Protection Effect

Among the many forms of protection, the 20 cm pitch raised structure has the best protection effect. It can be used in actual projects to achieve the best ecological and economic benefits.

With the rapid development of highway construction in my country, the environmental protection technology of highway slopes is developing rapidly, and various environmental protection technologies and protection forms are emerging in endlessly. At present, the widely used protection forms include composite nets, three-dimensional nets, geocells (grids), etc.

The slope protection structure is made of the polyester nonwoven geotextile factory price, which is processed and cut to a certain size and is used for ecological protection of the slope in the rainstorm area of ​​southern China.

1. Soil mixing. First measure the water content of the test soil, add water to the test soil according to the water content standard with a watering can after molding, stir evenly with a soil adjustment tool, and leave it for 24 hours.

2. Slope compaction. The slope is compacted in layers, each layer is 20 or 30cm, and it is compacted with a hammer from bottom to top. After pressing a layer, use a spatula to cut off the excess, and then use a spatula to scrape off the soil. Then lay polyester nonwoven geotextile for sale, buried 8 cm deep, covered 8 cm. The convex structure is buried 8 cm deep, and a semi-circular convex with a radius of 4 cm is set, and the wholesale polyester nonwoven geotextile covers 8 cm. Then fill the next layer of soil until the entire panel slot is filled.
3. Rainfall erosion. Use nozzles to spray water to simulate rainfall, the rainfall is kept at about 5 mm/min. The rainfall is measured by a rotameter and a water meter. Each time it rained for 10 minutes, a total of 6 spots of rain. The rainfall area can be adjusted through the nozzle so that the rainfall area is evenly distributed on the entire slope.

4. Rainwater collection. When it rains, the rainwater is collected by the sump, and the collected water and sediment are put into different sump barrels, weighed and recorded. Dry each sump to obtain sediment content.
