The present invention provides a gravity block type anchored retaining wall and a construction method therefor which is provided to simplify existing complex processes by using a gravity block type retaining wall to replace a conventional form, to secure economic feasibility by using plain concrete as backfill concrete, and to reduce the construction period of the retaining wall by making it unnecessary to install the form by using large precast gravity blocks designed to have excellent quality and transportability. The gravity block type anchored retaining wall is an anchored retaining wall which is constructed on the front side of a filling slope or of a cut slope to support earth pressure. The gravity block type anchored retaining wall comprises an earth retaining structure which includes an H pile, an earth plate and a permanent anchor, and which has a walling formed on the head of the permanent anchor, and which is constructed on the front side of a filling slope or of a cut slope; foundation concrete placed on the lower part of the front side of the earth retaining structure; at least one gravity block which is manufactured by pre-casting and installed together with other blocks by being arranged on top of each other from the foundation concrete; a hook type connection unit transversely connecting the walling of the earth retaining structure and the gravity block; and backfill concrete placed in a space between the earth retaining structure and the gravity block, wherein the earth retaining structure, the gravity block and the backfill concrete are integrated to form the anchored retaining wall. |
