EARTH REMOVING THREE-SHAFT DEEP MIXING TREATMENT DEVICE, AND THREE-SHAFT DEEP MIXING TREATMENT METHOD
To make it possible to suppress displacement of surrounding natural ground, cope with displacement distribution in a laminated ground, improve construction efficiency in an improvement area formed by three rotating shafts and further remove earth without mixing of a component of a solidification material.SOLUTION: An earth removing three-shaft deep mixing treatment device comprises: three rotating shafts 11A, 11B, 11c including agitating blades 14 at its tip portion and disposed in parallel; spirals 12 provided on respective outer peripheral surfaces of the three rotating shafts 11A, 11B, 11c; and solidification material discharge ports 13 discharging a solidification material from the tip portions of the rotating shafts 11A, 11B, 11c to the ground; in which the central rotating shaft 11B is configured to be able to rotate faster than the side rotating shafts 11A, 11C and to rotate in an opposite direction to those of the side rotating shafts 11A, 11C.SELECTED DRAWING: Figure 2
【課題】周辺地山の変位を抑制し互層地盤での変位分布にも対応することができ、かつ３軸の回転軸により形成される改良面積において施工効率の向上でき、さらに固化材の成分を混入させずに排土することができる。【解決手段】先端部に撹拌翼１４を備え並列に配置された３軸の回転軸１１Ａ、１１Ｂ、１１Ｃと、３軸の回転軸１１Ａ、１１Ｂ、１１Ｃの各外周面に設けられたスパイラル１２と、回転軸１１Ａ、１１Ｂ、１１Ｃの先端部から地盤に向けて固化材を吐出させる固化材吐出口１３と、を備え、中央回転軸１１Ｂは、側方回転軸１１Ａ、１１Ｃよりも高速で回転することが可能に設けられ、かつ側方回転軸１１Ａ、１１Ｃとは逆回転されるように設定されている構成の排土式３軸深層混合処理装置を提供する。【選択図】図２
