Description
水硬性を有する粉体を、前記貯水構造物内の貯水に投入し、前記貯水構造物内の漏水箇所を含む部位に沈積させ、所定期間養生することにより硬化させて遮水層を形成することを特徴とする(第1の発明)。
図1は、本実施形態に係る漏水補修方法の手順を説明するためのフローである。
養生ステップS30では、投入後、水底に沈積させた水硬性粉体10を十分に養生させるために所定の期間(例えば、1〜4週間)静置する。
図3は、PFBC灰又はジオシードのポリバケツ18への投入量をまとめた表である。
本検討で作製した供試体22の透水係数は、図5及び図6の結果をまとめると、2.5×10−5cm/s〜3.6×10−4cm/s程度であり、図7を参照すれば、透水係数の低い微細砂やシルトに相当する。すなわち、PFBC灰やジオシードを、貯水構造物12に投入することにより、貯水構造物12の底部に発生したクラック16の上方に、ある一定の圧縮強度と、微細砂やシルトと同程度の遮水性とを有する遮水層14が形成されることになり、貯水構造物内の水のクラックへの流通を遮断することになる。
