AI Technical Summary

Technical Problem

In rainy areas, slopes suffer from soil and rock erosion and reduced stability due to rainfall. Existing protection methods are difficult to combine effectively with vegetation greening and are not effective before the vegetation takes root. Furthermore, existing methods cause significant ecological damage and are costly.

Method used

The slope interception and drainage structure adopts a combination of zoned drainage, water diversion, and drainage, including interception ditches, drainage ditches, main water pipe trenches and secondary water pipe trenches, combined with gabion mesh bagged granular material and vegetation, and fixed with U-shaped nails. It is suitable for integration with other support structures to form effective protection.

Benefits of technology

It can effectively reduce the erosion of slopes by rainfall during both the construction and operation periods, improve slope stability, reduce soil loss, is highly adaptable, economical and has good ecological effects, and is suitable for slope protection in areas with heavy rainfall in the south.
