GROUND IMPROVEMENT MATERIAL INJECTION SYSTEM AND COLUMN ROW TYPE CONTINUOUS WALL CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To provide a ground improvement material injection system and a column row type continuous wall construction method that are operable using a single pump.SOLUTION: A ground improvement material injection system 1 used for a column row type continuous wall construction method comprises: a single pump 2 for supplying ground improvement material by using pulsation; a single switching valve 3 that is provided at a branch point of a path for the ground improvement material supplied from the pump 2 and switches the path for the ground improvement material in synchronization with the ground improvement material's pulsation; and a plurality of rods 7a, 7b, 7c that are in a straight-pipe shape and rotatably and vertically movably arranged so as to be laterally aligned, function as a path for injecting the ground improvement material having passed through the switching valve 3 into a hole of the ground, and stir the ground improvement material having been injected in the hole of the ground into in-situ soil.SELECTED DRAWING: Figure 1
【課題】１台のポンプで対応可能な地盤改良材の注入システム及び柱列式連続壁工法を提供する。【解決手段】柱列式連続壁工法に用いる地盤改良材の注入システム１は、地盤改良材を脈動で供給する１台のポンプ２と、ポンプ２から供給された地盤改良材の経路の分岐点に設けられ、地盤改良材の脈動に同期して地盤改良材の経路を切り替える１個の切替弁３と、直管状で鉛直に且つ回転及び昇降可能に各々が横に並ぶように配置され、切替弁３を経由した地盤改良材を地盤の穴に対して注入する経路として機能すると共に、地盤の穴に注入された地盤改良材を原位置土と撹拌する複数のロッド７ａ，７ｂ，７ｃと、を備えている。【選択図】図１
