With the development of engineering industry, the retaining wall is widely applied in engineering, but when the retaining wall is arranged on some mountain areas, some side slopes or some side slopes with landslides, steep slopes formed by highway cutting construction in the mountain areas and the like, higher requirements are provided for the protection of the retaining wall.
The traditional masonry retaining wall measures mainly adopt a stone masonry structure constructed by stones and cement mortar and directly adopt concrete and reinforced concrete as a gravity type retaining wall to support and protect the side slope.
Gabion retaining wall also called gabion retaining wall is a novel retaining wall structure developed in recent years and also belongs to a gravity retaining wall. The retaining wall is a retaining wall structure formed by filling block and slice materials into a net cage structure formed according to engineering design requirements and connecting twisted steel wires made of the same material as the net cage surface with a hexagonal mesh woven by corrosion-resistant and wear-resistant galvanized aluminum alloy or low-carbon steel wires coated with an organic coating.
