DEEP LAYER MIXING APPARATUS
PROBLEM TO BE SOLVED: To provide a deep layer mixing apparatus which can establish a desired columnar improvement body easily by eliminating unevenness in pressure applied to the side part of an improvement body.SOLUTION: A deep layer mixing apparatus comprises: a rod 20 which has a middle pipe with an excavation tooth 23 and a solidification material discharge port at the lowermost end part and an outer pipe installed outside the middle pipe and that rotationally drives the middle pipe and the outer pipe in the contrary direction mutually; an agitation mixing part 26 which has a middle pipe agitating blade 27 installed at the lower end of the rod 20 and rotating integrally with the middle pipe and an outer pipe agitating blade 28 rotating integrally with the outer pipe and which agitates and mixes an excavated ground and a solidification material; and a mixed soil guide part 34 which is installed in the agitation mixing part 26 and which can guide in-situ soil and a solidification material mixed in the agitation mixing part 26 to the side of the center position of the rod 20.SELECTED DRAWING: Figure 13
【課題】改良体の側方に与える圧力のムラを無くし、所望する円柱状をした改良体を容易に造成できる深層混合処理装置を提供する。【解決手段】最下端部に掘削歯２３及び固化材吐出口が設けられた中管と該中管の外側に装着された外管とを有し、中管と外管とが互いに相反する方向に回転駆動されるロッド２０と、ロッド２０の下端部に設けられていると共に中管と一体に回転する中管攪拌翼２７と外管と一体に回転する外管攪拌翼２８とを有し、掘削された地盤と固化材とを攪拌混合する攪拌混合部２６と、攪拌混合部２６内に設けられ、攪拌混合部２６内で混合された原位置土と固化材をロッド２０の中心位置側へ誘導可能な混合土誘導部３４と、を設けた。【選択図】図１３
