Construction method of strip-type fiber reinforcement for reinforced soil retaining wall

摘要

The present invention relates to a reinforced-soil retaining-wall structure which enables quick and easy connection of a band type fiber reinforcing material, can provide various connection methods therefor, and prevents stress from being concentrated in a connection part with a facing member during the sinking of a reinforced soil body, the reinforced-soil retaining-wall structure comprising: a facing member (10) having a reinforcing material insertion hole (20) buried therein; and a band type fiber reinforcing material (30) which is fitted into the reinforcing material insertion hole (20) of the facing member (10) and is laid on a reinforced soil body (G), wherein the reinforcing material insertion hole (20) comprises: two entrances (21, 22) which are each opened toward the rear side (12) of the facing member (10), and are spaced from side to side; and a through path (23) in which a predetermined curvature radius is formed from the two entrances (21, 22) to the inside of the rear side (12) of the facing member (10), wherein the two entrances (21, 22) have an inner surface (21a, 22a) opened perpendicularly to the rear side (12) of the facing member (10) and have an outer surface (21b, 22b) opened with the front side thereof being wide and the rear side thereof being narrow with respect to the rear side (12) of the facing member (10), whereby a flexible band type fiber reinforcing material (30) is inserted into one entrance (21, or 22) and is drawn out from the other entrance (22 or 21), and then is connected, laid on the reinforced soil body, and buried.
