REPAIR STRUCTURE OF UNDERGROUND CONCRETE STRUCTURE AND REPAIR METHOD
To provide a repair structure of an underground concrete structure and repair method that can perform repair work at as low a construction cost as possible and can eliminate peeling and exfoliation of the repair structure to be expected to bring long-term durability performance.SOLUTION: In a repair structure 60 for an underground concrete structure, a laminate in which buffer layers 40 and repair cement layers 50 are laminated in order from the ground side to the surface side of a removal portion 20 is formed in the removal portion 20 on the surface of the underground concrete structure, and the buffer layer 40 is a mixture of EVA resin powder and hydraulic powder.SELECTED DRAWING: Figure 6
【課題】可及的安価な工費にて補修施工を行うことができ、補修構造の剥離や剥落を解消して長期耐久性能を期待することのできる、地中コンクリート構造物の補修構造及び補修方法を提供する。【解決手段】地中コンクリート構造物の補修構造６０であって、地中コンクリート構造物の表面の撤去部２０において、撤去部２０の地山側から表面側に向かって順に、緩衝層４０と補修セメント層５０とが積層されている積層体が形成されており、緩衝層４０が、ＥＶＡ樹脂の粉末と水硬性粉末との混合体である。【選択図】図６
