ROAD REINFORCEMENT STRUCTURE USING FILLING FRAME AND REINFORCING STEEL WIRES

WIPO Patent Application WO/2018/062691

A1

The present invention comprises a bearing layer formed on the upper surface of the ground, and a surface layer formed on the upper surface of the bearing layer and made from a water permeable material, wherein the bearing layer comprises: a filling frame in which a plurality of plates are assembled to be orthogonal to each other so as to form a plurality of filling spaces; reinforcing steel wires horizontally passing through the plates of the filling frame; reinforcing blocks formed in some filling spaces among the plurality of filling spaces; and filling aggregates filled in the filling spaces, in which the reinforcing blocks are not provided, among the filling spaces. Mortar or concrete is poured into the filling spaces and cured therein such that the reinforcing blocks are formed. The reinforcing blocks are formed by skipping the alternate filling spaces, and the reinforcing blocks formed in the filling spaces of odd and even rows are arranged to be alternated with each other. According to the present invention, the load bearing property of the bearing layer is reinforced and water permeability is uniformly maintained such that problems such as surface cracking and ground subsidence are reduced.
