には撹拌翼４が突設されている。(Specific Description of the Invention Based on Drawings) In FIG. 1, which is an overall view of the device of the present invention, a rotary shaft 1 is hollow and extends downward from a rotary drive machine 3 suspended from a working machine 2 so as to be movable up and down. , a stirring blade 4 is provided protruding from its lower end.
撹拌翼４の数は任意であり、また、図示のよう
に１段ではなく、上下に間隔をおいて多段に設け
てもよい。 The number of stirring blades 4 is arbitrary, and instead of one stage as shown in the figure, they may be provided in multiple stages at intervals vertically.

になつている。 Some of the stirring blades 4 are configured as hollow bodies with only the bottom surface open, and the soil improvement agent is supplied from the ground into the internal space (the second
In the case shown in the figure, the ground improvement agent is in the form of powder and granules, and is mixed with compressed air and placed on the rotating shaft.
The tip opening 6 of the supply pipe 5 facing the inside of the stirring blade 4 is oriented in a direction in which the mixed fluid moves forward while swirling, so that the mixed fluid passes through the stirring blade. While moving toward the tip of the stirring blade 4, the soil improving agent that has moved to the outside due to the action of centrifugal force comes into contact with the ground soil at the lower open part of the stirring blade 4 and adheres thereto. The separated air is agitated and mixed with the ground soil as it rotates, while the separated air is collected on the ground via a collection pipe 7 protruding from the stirring blade 4 and a collection passage 8 inside the rotating shaft 1 that communicates with the collection pipe 7. It's getting old.

中と同じ態様で開放部に向かつて地盤改良剤を吐
出し供給することもできる。 As mentioned above, the illustrated example uses a powder-like ground improvement agent and separates it from compressed air using centrifugal force. By extending the mixing fluid to the tip of the stirring blade 4 and providing a jet hole for the mixed fluid downward in this extended part, the mixed fluid can collide with the ground soil at the open part of the stirring blade 4, and only the ground improvement agent can be attached to the ground soil. In addition, when using a slurry as a soil improvement agent, for example, by applying the required air pressure in the stirring blade 4, the soil improvement agent can be directed toward the open area in the same manner as in the atmosphere. It can also be dispensed and supplied.

る。 In FIGS. 3 and 4, reference numeral 9 denotes a lid provided on the open part of the stirring blade 4, and one side edge in the width direction is pivoted 10 to the outer lower end of one side wall of the stirring blade 4. When the rotating shaft 1, through which the soil improvement agent is supplied, rotates in the forward direction, it rotates in the direction of arrow A to open, and when it rotates in the opposite direction, it rotates in the opposite direction to close.

パ１１を設けるのが好ましい。 The lid 9 opens and closes automatically due to the resistance of the soil acting on it, but in order to effectively apply the opening and closing force, the free edge of the lid 9 is made to slightly protrude outside the stirring blade 4, and the shaft is It is preferable to provide a stopper 11 at the stopper 10 to prevent the lid 9 from rotating further than the position indicated by the chain line in FIG.

ので、その実用性は極めて高い。(Effects of the invention) As described above, in the present invention, since the stirring blade is configured as a hollow body with only the bottom open, it is possible to supply the soil improvement agent in a preferable manner regardless of the type of soil improvement agent. Not only can effective ground improvement be expected, but the provision of a lid on the open part of the stirring blade that can be rotated to open and close by switching the rotating direction of the rotating shaft between forward and reverse directions eliminates the need to supply soil improving agents. in some cases,
The rotating shaft can be rotated in the direction in which the lid closes to close the open part with the lid to prevent ground soil from entering the internal space of the stirring blade.Also, when supplying the soil improvement agent, the rotating shaft can be rotated in the opposite direction. Its practicality is extremely high because it can be rotated to open the lid and supply soil improvement agent without any problems.
