Description
上記実施形態では、気体として空気を用いた。しかし、空気以外の気体を用いても構わない。
Claims (3)
- コンクリート構造物に穿孔し、この孔から所定圧力で所定量の気体を前記孔に連通する空洞に流入又は流出(以下、「流入等」という。)させ、
圧力変動を時間情報と共に測定し、
測定圧力を前記所定圧力で除した圧力比の時間変動を求め、
求めた圧力比の時間変動において急激な圧力比低下の後圧力比が緩和され始めた時間帯における圧力比を求め、
測定圧力比と既知の空洞容積との相関を検量線として予め求めておき、
前記検量線と求めた圧力比とを比較することにより前記空洞の容量を求めるコンクリート構造物の空洞検査方法。 - 前記時間変動が時間の経過と共に圧力比零に漸近することにより前記空洞に対する漏洩孔の有無を判定する請求項1記載のコンクリート構造物の空洞検査方法。
- 前記空洞がPC構造物におけるシース管内のグラウト未充填部である請求項1又は2記載のコンクリート構造物の空洞検査方法。
