LENGTH CONTROL FOR COUPLER USING REINFORCED EARTH RETAINING WALL A METHOD OF CONSTRUCTION

摘要

PURPOSE: A reinforced earth retaining wall installation method using a length adjustment coupler is provided to improve the compressive force of a reinforced earth retaining wall lamination and lower tensile strength by removing the installation of a connection bar between reinforced earth retaining wall blocks. CONSTITUTION: A reinforced earth retaining wall installation method using a length adjustment coupler comprises the following steps: linearly arranging a plurality of reinforced earth retaining wall blocks(10); forming coupling holes in the sides of the reinforced earth retaining wall blocks; coupling connection re-bars(20) to the coupling holes; separately connecting a plurality of connection bars to the connection re-bars in the longitudinal direction; and interconnecting a soil nail(2) which is installed on the slope surface of a cutting part and the connection bar through a length adjustment coupler.
