REPAIR METHOD OF RETAINING WALL STRUCTURE
PROBLEM TO BE SOLVED: To provide a repair method of a retaining wall structure that can restore the overall retaining wall structure to a sound condition by enabling repair only of a portion of the retaining wall where it needs to be repaired, in the retaining wall structure having been constructed by a reinforced earth method.SOLUTION: A repair method is for a retaining wall structure constructed by a reinforced earth method and comprising a plurality of panel-form wall surface material bodies, one or more connection metal fittings provided on a rear surface side of the wall surface material body, and a reinforcement material 30 tucked in a banking layer 40 provided on the rear surface side of the wall surface material body and connected with the connection metal fitting. The repair method includes the following steps for: removing the wall surface material body to be repaired, at the same time releasing a connection between the connection metal fitting and the reinforcement material 30 and removing the connection metal fitting; connecting an edge part of the existing reinforcement material 30 with a linking metal fitting 50, and installing a repairing wall surface material body 70 having a linking hole 71; and placing the linking metal fitting 50 in a linking hole 71, connecting a tensile force application metal fitting 60 disposed near the linking hole with the linking metal fitting 50, and applying tensile force on the reinforcement material 30.SELECTED DRAWING: Figure 9
【課題】補強土工法による擁壁構造において、擁壁構造の一部が補修を必要とする場合に、補修が必要な擁壁部分のみを補修することにより擁壁構造全体を健全な状態に戻すことができる擁壁構造の補修方法を提供する。【解決手段】パネル状の複数の壁面材本体と、壁面材本体の裏面側に設けられた１又は複数の接続金具と、壁面材本体の裏面側に設けられた盛土層４０に挟み込まれ、接続金具と結合された補強材３０とからなる補強土工法により構築された擁壁構造の補修方法であって、補修すべき壁面材本体を除去し、同時に、接続金具と補強材３０の結合を解除すると共に接続金具を除去し、既存の補強材３０の端部と連結金具５０を結合し、連結孔５０を備えた補修用壁面材本体７０を設置すると共に、連結金具５０を連結孔７１に配置し、連結孔近傍に配置した張力付与金具６０と連結金具５０を結合し、補強材３０に張力を付与する構成の補修方法とした。【選択図】図９
