ルセメント連続壁は採用し得ないこともあった。(Problems to be solved by the invention) In the conventional method of constructing a concrete pile, while a solid concrete pile can be constructed, the discharge amount of excavated mud becomes enormous, so the construction cost for the treatment increases significantly, In addition, it causes a delay in the construction period, and at the present time, there are few treatment places for industrial waste, and there is a limit to new development, so there was a problem such as difficulty in treating excavated mud. In addition, when mud is soil-cemented in an excavation hole, the strength of the soil-cement pile or the soil-cement continuous wall is significantly different depending on the position in the depth direction, so it is often unusable. It was Because the cement milk is injected during excavation or stirring, it is possible to inject the necessary amount according to the amount of mud, but the mixed state is not always uniform and it is difficult to adjust the water content. Yes, and even if it is stirred, it is impossible to vertically stir over the entire length of the long pile (for example, 20m to 40m).
At a certain position, the cement milk was low, and sometimes the cement milk was completely absent. For example, the reliability of strength of soil cement piles was extremely low, and it was extremely difficult to detect this. Therefore, as a countermeasure against these problems, it is often the case that an excessive amount of cement milk is used to generate a large amount of residual soil and soil discharge, and structures requiring high strength include soil cement piles or continuous soil cement walls. Was not possible in some cases.

An excavating blade 12 provided with a stirring rod 9, a kneading drum 10 and an excavating blade 11 is used to excavate a pile hole while kneading mud produced by excavation into a hole wall. The mud that flows out as the excavation progresses is collected in the stirring tank 3, and an appropriate amount of cement and additives (for example, the amount of cement is about 15% of the excavated soil) and, if necessary, water are added to the stirring tank 3 and stirred. By doing so, a homogeneous soil cement 4 is produced. The soil cement 4 is sequentially filled from the bottom of the excavation hole 2 upward by the transfer pipe 5. Therefore, when the soil cement 4 is hardened, a homogeneous soil cement pile 7 is constructed.

In the above, since the excavated soil is mostly used as the material of the soil cement 4, the amount of excavated soil is drastically reduced (for example, the amount of excavated soil is 30% or less of the excavated soil). In the above, the excavated soil is turned into mud and is conveyed to the stirring tank by the suction pipe 24, for example.

時間を著しく節減することができる。Therefore, as the excavating rod 12 advances, the excavated soil is stirred by the stirring rod 9 to be mud, and is kneaded into the hole wall by the kneading drum 10. In this case, if a small amount of pressurized water is jetted from the tip of the rotary shaft 8, the excavated soil becomes a mud with an appropriate amount of water and can be easily kneaded (provided that groundwater does not come out). In this way, when the drilling hole 2 reaches the predetermined depth, the soil cement 4 is sequentially fed from the drilling rod 12 from the bottom of the piling hole to replace the mud, and the soil cement 4 is filled into the drilling hole 2. After that, it can be hardened to build the soil cement pile 13. Soil cement 4 is prepared by mixing an appropriate amount of cement and additives into the muddy water generated by the above replacement,
By filling the second drill hole 2, by repeating this process, the amount of excavated soil will be extremely small (about 10% of excavated soil), and the waste disposal labor, cost and time will be significantly reduced. You can

While excavating 15 with three excavating rods 12a, 12b, 12c at the same time,
The excavated soil is turned into mud, and a part of it is converted into each drum 10a, 10b, 10c.
To dig into the hole wall. When the drill hole 15 reaches the intended depth in this way, the soil cement 4 made by mixing the soil and the cement produced by the excavation in the agitation tank 3 on the ground has hoses 19a, 19b, 19c. Through the drilling rods 12a, 12b, 12c, respectively, from the bottom of the drilling hole.

Since the soil cement was mixed with additives and turned into soil cement, and this soil cement was returned to the inside of the drill hole and hardened integrally with the reinforcing material inserted in the drill hole, the hole wall was leveled with the kneaded mud. It is also reinforced and it does not collapse during construction,
This has the effect of forming a homogenized and strengthened drill hole. Furthermore, since soil cement is generated on the ground, it will be possible to homogenize it, and quality control will be facilitated.Therefore, it will be possible to dramatically increase the strength reliability of the soil cement pile or continuous wall due to its hardening. is there.
