GROUND IMPROVING NEGATIVE PRESSURE DRIVE UNIT USING EJECTOR PUMP
PROBLEM TO BE SOLVED: To provide a ground improving negative pressure drive unit capable of efficiently converting a drive water of an ejector to water absorbing force and improving water absorbing efficiency.SOLUTION: A ground improving negative pressure drive unit comprises: a water reservoir 10 which reserves water absorbed through a water absorbing pipe 5 liking to a drain material 2; an ejector pump 11 which uses the water in the water reservoir as drive water; and a drainage pump 28 which discharges the water in the water reservoir 10. A water absorbing pipe 5 is communicated with an absorption port of the ejector pump 11. The absorbed water is discharged in the water reservoir 10 by depressurizing the water absorbing pipe 5 by the ejector pump 11. The water in the water reservoir 10 is recycled as the drive water of the ejector pump 11. An absorption port 27 of the ejector pump 11 is positioned under the water surface in the water reservoir 10 and a drainage port is opened above the water surface.SELECTED DRAWING: Figure 1
【課題】エジェクターの駆動水を効率よく吸水力に変換でき、吸水効率を高くした地盤改良用負圧駆動装置。【解決手段】ドレーン材２に通じる吸水パイプ５を通して吸引された水を貯留する貯水槽１０と、その内部の水を駆動水とするエジェクターポンプ１１と、貯水槽１０内の水を排出する排水ポンプ２８とを備え、エジェクターポンプ１１の吸引ポートに吸水パイプ５を連通させ、エジェクターポンプ１１により吸水パイプ５内を減圧させて吸引した水を貯水槽１０内に吐出させ、貯水槽１０内の水をエジェクターポンプ１１の駆動水として循環使用し、エジェクターポンプ１１の吸引ポート２７を貯水槽１０内の水面下に位置させ、排水ポートを水面上に開口させる。【選択図】図１
