る方法(特願昭55−183736号)を提案している。 The present applicant has already discovered that as a method suitable for constructing a basement in particular in soft ground, a columnar hole is excavated while the internal soil is stirred, and at the same time, the soil and a soil hardening agent are mixed to form a column in the ground. At the same time, adjacent columns partially overlap each other to form a row of columns defining the periphery of the basement to be formed, and this row of columns hardens to form a column underground. We have proposed a method (Japanese Patent Application No. 183736/1983) of forming a basement by digging roots inside the underground wall after it becomes a wall.

5に傾斜が生じないようにする。 The invention will now be described with reference to the illustrated embodiments. The main frame 1 in the form of a portal canine is movable on endless tracks 2, 2 provided on the left and right sides of its lower end, and its length L in the running direction is set larger than its width W. A pair of hydraulic cylinder devices 3 are erected at the front and back of the upper end of the main frame 1, and at the lower end of the downwardly projecting piston rod 4 is a support base 5 which is flat and located at the center of the main frame in the width direction. is supported in suspension. Therefore, the support base 5 moves up and down by supplying and discharging pressure oil to the hydraulic cylinder device 3. In this example, the hydraulic cylinder device 3 directly suspends and supports the support base 5 in a vertically movable manner, but the main frame 1 may be provided with a vertical movement guide for the support base 5. Of course, the supply and discharge of pressure oil to a pair of hydraulic cylinder devices 3 or a larger number of hydraulic cylinder devices 3 is controlled so that all piston rods 4 move at the same speed and height, so that the support base 5 does not tilt. .

も同様の下端部14が設けられている。 Below the stirring rods 8, stirring blades 10 are arranged in series, each projecting in the radial direction. This stirring blade 10 excavates and stirs the ground by rotating the stirring rod 8, and at the same time mixes a milky soil hardening agent into the stirred soil, so it has a plurality of discharge ports at different radial positions. 11 is opened. This discharge port 11 communicates with a soil hardening agent pressure pump 13 outside the stirring mixer via a stirring blade passage, a shaft passage of the stirring rod 8 (both not shown), a swivel joint 9, and a high-pressure flexible hose 12. ing. A similar lower end portion 14 is also provided at the lower end of the stirring rod 8.

撹拌ロツドを互いに反対方向とする。 The length of the stirring blade 10 is set such that a columnar hole dug by the stirring blade partially overlaps a columnar hole dug by an adjacent stirring blade, and stirring blades of adjacent stirring rods do not interfere with each other. The height positions are different from each other. The rotating directions of the stirring rods 8 are opposite to each other in order to prevent the wall surfaces of adjacent excavated columnar holes from collapsing and to perform stirring and mixing in a stable state.

わち地中壁の強度は一様で強くなるのである。 Accordingly, in this stirring mixer having the above configuration, the main frame 1 is run on the endless tracks 2, 2 on the ground where the underground wall is to be constructed, and then the stirring rod 8 is rotated by the hydraulic motor 6. At the same time, when the support base 5 is lowered by the hydraulic cylinder devices 3, 3, a columnar hole is bored in the ground by the stirring blades 10, and at the same time, the excavated earth and sand in the columnar hole is stirred.
The depth of the columnar hole is determined by the amount of descent of the support base 5, so when the depth of the columnar hole reaches the desired depth, the support base 5 is raised. ) During the rising operation, the pressure pump 13
is driven to eject milky soil hardening agent from the discharge ports 11 and 14. Then, the soil hardening agent and the excavated soil are well stirred and mixed in the columnar hole by the stirring blades 10, so that the strength of the columnar array, that is, the underground wall, which is later naturally hardened, becomes uniform and strong.

論である。 In this embodiment, an underground column row is formed in which four adjacent columns overlap each other at a time.
Before this underground column array hardens, the endless tracks 2, 2
By moving the main frame 1 using A middle wall can be formed. FIG. 4 shows an example of a columnar hole 15 and its formation line B when a basement is formed in the ground surrounded by a straight line A. It goes without saying that the device of the present invention can be used not only for forming basements but also for forming underground walls for purposes such as construction.
