This slope protection form has the advantages of good durability and easy maintenance, but has the disadvantages of high construction difficulty and cost. Anchor rod slope protection is a common slope protection form, which forms a protective layer by hanging net on anchor rod fixed in stable stratum to prevent soil landslide and groundwater impact. This slope protection form has the advantages of good durability and easy maintenance, but has the disadvantages of high construction difficulty and cost. Net hanging slope protection is a common slope protection form, which forms a protective layer by hanging steel mesh on the slope surface to prevent soil landslide and groundwater impact. This slope protection form has the advantages of simple construction and low cost, but has the disadvantages of poor durability and high maintenance difficulty. Retaining wall slope protection is a common slope protection form, which builds retaining wall on the slope surface to prevent soil landslide and groundwater impact. This slope protection form has the advantages of good durability and easy maintenance, but has the disadvantages of high construction difficulty and cost.
