Abstract
The utility model discloses a novel geocell ecological retaining wall which is composed of a reinforced layer in a roadbed and a wall body. The reinforced layer is composed of a plurality of geocells I which are arranged in plane mode and padding filled in grids of the geocells I. The wall body is formed by piling up multiple layers of geocells II. Backfill is filled into grids of the geocells II. The bottom of the wall body stretches into a foundation and is connected with rivets of the foundation. Multiple geocell reinforced layers are arranged in the roadbed so that characteristics of high modulus and high strength of the geocells can be fully used of. Net-shaped sand chambers formed in the roadbed provide large side direction constraint force, and tensile strength, shearing strength and overall stability are all greatly improved. And when the flexible wall body bears too much pressure from the backfill, the flexible wall body can transform in bending and shearing mode so as to reduce a backfill pressure load and improve bearing capacity of the entire retaining wall structure.
