Description
脱水装置が、土と分離した水を集める集水槽を備え、集水槽内とチャンバ内とが送水管により互いに連結され、送水管には集水槽内の水をチャンバ内に圧送するポンプが設けられたことも特徴とする。
集水槽内とチャンバ内とがポンプ付きの送水管により互いに連結されたので、脱水装置により土と分離された水をチャンバ内に戻して粘度調整用の水として再利用でき、水の有効利用が図れる。

9 脱水装置、42 集水槽、43 送水管、44 ポンプ、53 排水機構。
Claims (2)
- 胴筒と胴筒の前端に設けられた回転カッタヘッドとを備え、胴筒の内側には掘削土を取り込むチャンバとスクリューコンベアと凝集剤添加攪拌装置と脱水装置とを備え、チャンバ内で掘削土と水とを混合して形成した泥土による圧力で切羽の安定を図りながら掘削を行うシールド掘削機において、チャンバ内の泥土を後方に送るスクリューコンベアの泥土排出部と凝集剤添加攪拌装置の入口とが泥土をチャンバ内の圧力によりスクリューコンベア経由で凝集剤添加攪拌装置に圧送できるように密閉状態となるよう互いに連結され、凝集剤添加攪拌装置の出口と脱水装置の入口とが互いに連結されたことによって、チャンバから脱水装置の土排出口及び集水槽まで、泥土を導く内部経路が外部と遮断されたことを特徴とするシールド掘削機。
- 脱水装置が、土と分離した水を集める集水槽を備え、集水槽内とチャンバ内とが送水管により互いに連結され、送水管には集水槽内の水をチャンバ内に圧送するポンプが設けられたことを特徴とする請求項1に記載のシールド掘削機。
