Title:
GROUND IMPROVEMENT DEVICE
Document Type and Number:
Japanese Patent JP3665306
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a ground improvement device for homogeneously dispersing an improving material by solving the problem that there is anxiety for reliability due to being unable to sufficiently confirm whether or not such kneading is surely and uniformly performed because excavating earth and the improving material are mixed and kneaded conventionally in the ground.
SOLUTION: This ground improvement device has an excavating shaft body extending in the vertical direction and an excavating blade body formed by extending in the radial direction from a lower end part of the excavating shaft body. An improving material delivery passage is arranged in the extending direction in the excavating blade body, and the improving material is delivered over almost the whole width of an extending width of the excavating blade body via the improving material delivery passage. Thus, the improving material can be delivered over almost the whole width of the extending width of the excavating blade body so that the improving material can be already homogeneously dispersed in a stage of being delivered in the excavating soil.
