CONSTRUCTING METHOD OF CONNECTING TYPE RETAINING WALL USING HIGH PERFORMANCE SHOTCRETE COMPOSITION

摘要

The present invention relates to a method to construct a combinational retaining wall by using a high performance shotcrete composite. According to the present invention, the method includes: a surface treatment step of removing falling rocks and soil on a slope and treating its surface; a drainage facility installation step of installing a drainage facility by connecting the facility with the rear side of a structure, installed on a side of the slope, in order to prevent the permeation of water into the structure or drain the structure; a reinforcement material installation step of installing a reinforcement material on a side of the slope to reinforce the slope; a reinforcement bar installation step of installing a reinforcement bar after the reinforcement material installation step; a composite placement step of attaching a shotcrete composite to the surface of the slope to be placed; a surface finishing step of imprinting an atypical form on the surface of the shotcrete composite to be placed through the composite placement step; a spray curing step of spraying water to the composite and then curing the composite to prevent a contracting crack on a carved surface of the shotcrete composite; and a coating step of applying coloring and coating agents to the surface of the slope in order to form a surface texture similar to a natural rock after the spray curing step. As such, the present invention is capable of reinforcing the slope while forming various patterns or colors on the surface of the reinforced slope by placing a high performance wet shotcrete composite on a reinforcement-required slope, and securing the stability of the slope while enabling convenient and efficient slope reinforcement by installing the reinforcement material for the slope and then placing highly substantial and highly durable wet shotcrete on a side of the reinforcement material.
