Summary:PROBLEM TO BE SOLVED: To provide a partial repairing method for a reinforcing soil wall by which only a damaged wall surface material can be partially repaired and the other structure is not influenced.SOLUTION: A partial repairing method for a reinforcing soil wall is provided for a reinforcing soil wall comprising multiple wall surface materials each including a panel part and a protrusion protruding from the back of the panel part; a banking body which is positioned at a back side of the multiple wall surface materials; a drain layer which is interposed between the wall surface materials and the banking body; and a connector for connecting the wall surface materials with the banking body. The partial repairing method includes: a drilling hole step for forming an injection hole that reaches the drain layer, on the panel part of a damaged wall surface material; an injection step for injecting a solidification agent from the injection hole into the drain layer and partially solidifying the drain layer; a cutting step for cutting a part of or the entire panel part of the damaged wall surface material and forming an installation space; a bar arrangement step for arranging steel bars within the installation space; and an installation step for installing concrete within the installation space.SELECTED DRAWING: Figure 4 【課題】破損した壁面材のみを部分的に補修でき、他の構造に影響を与えない補強土壁の部分補修方法を提供すること。【解決手段】本発明の補強土壁の部分補修方法は、パネル部とパネル部の背面から突出した突出部とを備えた複数の壁面材と、複数の壁面材の背面側に位置する盛土体と、壁面材と盛土体の間に介在する排水層と、壁面材を盛土体に連結するための連結具と、を備える補強土壁の部分補修方法であって、破損した壁面材のパネル部に排水層に至る注入孔を削孔する、削孔工程と、注入孔から排水層内に固化剤を注入して排水層を部分的に固化させる、注入工程と、破損した壁面材のパネル部の一部または全部を切除して打設空間を形成する、切削工程と、打設空間内に鉄筋を配筋する、配筋工程と、打設空間内にコンクリートを打設する、打設工程と、を備えることを特徴とする。【選択図】図４
