JOINT FOR CONCRETE PRESSURE-FEEDING PIPE
To provide a joint for a concrete pressure-feeding pipe for detecting whether the flowability of concrete in the pressure-feeding pipe has decreased.SOLUTION: A joint (inspection joint 10) that connects a pressure-feeding pipe on the side of a concrete supply location and a pressure-feeding pipe on the side of a concrete placement location and to which an inspection apparatus for inspecting the fluidity of pressure-fed concrete can be attached is composed of a cylindrical joint body 11 with a through hole 11a formed on its side, a transmissive portion 12c (transmissive member) made of a material that transmits elastic waves and is placed inside the through hole 11a, and a storage unit 12a made of an insulating member that is placed between the inner surface of the through hole 11a and the outer surface of the transmissive portion 12c to connect the transmissive portion 12c and the joint body 11. The inspection apparatus is a transmitter that transmits elastic waves into the concrete and a receiver that receives the elastic waves having propagated in the concrete. The insulating member is made of a material that does not allow elastic waves from the transmissive portion 12c to propagate into the joint body 11.SELECTED DRAWING: Figure 2
【課題】圧送管中のコンクリートの流動性が低下したか否かを検出するためのコンクリート圧送管の継手を提供する。【解決手段】コンクリートの供給場所側の圧送管とコンクリートの打設場所側の圧送管とを接続するとともに、圧送されるコンクリートの流動性を検査するための検査機器が取付け可能な継手（検査用継手１０）を、側面に貫通孔１１ａが形成された筒状の継手本体１１と、貫通孔１１ａ内に配置された、弾性波を透過する材料から成る透過部１２ｃ（透過部材）と、貫通孔１１ａの内周面と透過部１２ｃの外周面との間に配置されて透過部１２ｃと継手本体１１とを連結する絶縁部材から成る収納部１２ａとから構成した。また検査機器を、弾性波を前記コンクリート内に送信する送信機とコンクリート内を伝搬した弾性波を受信する受信機とした。絶縁部材は、透過部１２ｃからの弾性波が継手本体１１に伝播しない材料から構成される。【選択図】図２
