CONCRETE STRUCTURE REPAIRING METHOD
To provide a concrete structure repairing method capable of repairing the foundation of a concrete structure hollowed due to scouring and the stringer of a stairway using the existing concrete structure.SOLUTION: This concrete structure repairing method includes: a first step of disposing a reinforcing beam 31 on the outer surface of each stringer 13, providing a reinforcing rod 37 in a penetrating manner so as to be over each reinforcing beam and each stringer and pass on a tread 11, and fixing each reinforcing beam to the outer surface of each stringer; a second step of forming a dead space by forming a foundation surface below a concrete structure into a stepped shape; a third step of arranging form plates on the outer surfaces of both stringers; a fourth step of forming a through-hole through the tread; a fifth step of filling the dead space with filling concrete from the through-hole; and a sixth step of inserting a pile member 45 into the through-hole and driving the pile member into a roughly horizontal part of the foundation formed into the stepped shape.SELECTED DRAWING: Figure 12
【課題】既設のコンクリート製構造物を利用しつつ、洗堀により空洞化したコンクリート製構造物の基礎、及び階段の側桁を補修することができるコンクリート直打ち構造物の補修工法を提供する。【解決手段】各側桁１３の外面に夫々補強桁３１を配置すると共に、各補強桁、及び各側桁に跨がり、かつ、踏面１１上を通過するように補強ロッド３７を貫通させて各補強桁を各側桁の外側面に夫々固定する第１の工程と、コンクリート製構造物下方の地盤面を段切形成して空所を形成する第２の工程と、両側桁の外側面に型枠板を配置する第３の工程と、踏面を貫通する貫通孔を形成する第４の工程と、貫通孔から空所内に間詰めコンクリートを充填する第５の工程と、貫通孔内に杭部材４５を挿入し、段切形成された地盤の略水平面部分に杭部材を打ち込む第６の工程と、からなる。【選択図】図１２
