Abstract:
A method for constructing a concrete retaining wall structure, comprising the steps of:establishing a steel skeleton comprising basal H beams, aerial H beams, L beams, structural steel tubes and steel plates, said basal H beams and said aerial beams being arranged in a direction parallel with the earth's surface and at a significant angle to the earth's surface, respectively, at such spaced intervals and dimensions that the retaining wall structure has sufficient bending resistance to overcome active earth pressures, said L beams, said structural steel tubes and said steel plates being provided as reinforcements between said arranged H beams; applying watertight concrete to the H beams formed as bases of the steel skeleton in the horizontal direction to support the steel skeleton; providing wire meshes onto the vertically directed H beams, the L beams, the structural tubes and steel plates; coating the wire mesh-mounted structure with water-permeable concrete to form a stepped or embossed external surface; and covering the concrete with artificial greening soil, the artificial greening soil allowing the growth of flora therein.
