Claims (5)
- 地盤改良のために地中に高圧噴射された液状の固化材と原地盤中の土砂が混合したスラリーを利用するスラリー利用装置において、
液状の固化材を高圧噴射する固化材高圧噴射口を備えたロッドと、
前記ロッドの外周側面に設けられ、前記固化材高圧噴射口から噴射された固化材と原地盤中の土砂とが混合したスラリーを捕捉吸引するスラリー受容部と、
空気又は水を所定圧で噴出する噴出口と、
前記スラリー受容部と連通しかつ前記噴出口の近傍に設けられ、前記スラリー受容部から捕捉吸引されたスラリーを噴出するスラリー再噴出部を有し、
スラリーが廃液となって地上に排出される前に、地中において前記スラリー受容部からスラリーを捕捉吸引し、続けて前記スラリー再噴出部から噴出されるスラリーが前記噴出口から噴出される空気圧または水圧により再度加速して所定域の地盤を改良するスラリー利用装置。 - 前記噴出口は、前記スラリー受容部の近傍に設けられていることを特徴とする請求項1記載のスラリー利用装置。
- 前記スラリー受容部は、凹形の形状をしており、
前記噴出口は、凹形の前記スラリー受容部の内側に配置し、円周上および該中心部分に設けられ
前記スラリー再噴出部は、前記円周上に設けられた噴出口と前記中心部分に設けられた噴出口の間に配置されていることを特徴とする、請求項1または2に記載のスラリー利用装置。 - 前記噴出口は、リング状または多孔状に複数個配置されたことを特徴とする請求項3記載のスラリー利用装置。
- 地盤改良のために地中に高圧噴射された液状の固化材と原地盤中の土砂が混合したスラリーを、スラリーが廃液となって地上に排出される前に、ロッドの外周側面に設けられたスラリー受容部により捕捉吸引し、前記スラリー受容部の近傍に設けられた噴出口により空気又は水を高圧で噴出して、前記噴出口の近傍に設けられたスラリー再噴出部により噴出されるスラリーを再度加速して所定域の地盤を改良するスラリー利用方法。
