Description

Retaining wall structure combining ecology and rigidity

technical field

The utility model relates to the technical field of retaining wall structures, in particular to a retaining wall structure combining ecology and rigidity.

Background technique

In urban river management, it is usually necessary to set up retaining walls at the slope of the river to prevent the foundations on both sides of the river from collapsing under the action of water erosion, resulting in serious consequences such as road interruption and building damage.

The Chinese patent with the publication number CN205348098U discloses a retaining wall structure for a river course. The retaining wall structure includes at least a first retaining wall main body formed by stacking gabions. The gabions include a cage body and are filled into the cage The block material in the body and the gelling material poured into the cage, the gelling material at least fills the gap between the adjacent block materials to bond the block material in the cage into a whole structure . However, the retaining wall structure often ignores its damage to the environment in addition to enhancing the strength of the wall. The retaining wall structure reduces the material exchange between the soil and the water body, which makes the originally vibrant river lose its vitality, resulting in clean water. The growth of functional aquatic plants is difficult, and the self-purification ability of river water is reduced.
