た。＠As a method of constructing underground piles while suppressing noise and vibration, conventional methods involve rotating the pile cylinder and excavating the vicinity of the tip of the cylinder with an earth auger inserted into the pile cylinder. A method is adopted in which the cylinder is inserted. However, in this case, as the cylindrical body advances (the soil near its tip is first discharged by the earth auger), it is not possible to obtain sufficient supporting coal from the surrounding ground of the pile, and the discharged soil is There was a problem in that the amount was large and the BiK process required time and effort.

It is recommended to eject a fluid such as air or pressurized water from the through hole (3), and eject the ejected fluid from the through hole (3) to remove adhered soil and make the insertion easier. ,
If the insertion resistance of the cylinder (1) increases due to the ground breaking when inserting the cylinder, air or a fluid such as water is injected from the nozzle μ (6), and the pressure of the fluid increases the pressure of the cylinder. It may also be helpful in transporting the patient out of the body, making it easier for people to transport it.

率よく構築させることが可能になった。In other words, the soil near the tip of the cylinder is removed by the earth removal tool.
) Since the cylinder is inserted while pressing against the surrounding ground, the soil around the shoulders of the cylinder becomes hard and dense, so the cylinder +11
The amount of soil that must be removed is reduced due to the support provided by the ground surrounding the tube, and the amount of soil that enters the inside of the cylinder due to insertion is reduced. less. Even if earth and sand adhere to the earth ejector (2) when inserting the cylinder, the earth ejector (2) is cleaned and as much of the adhering earth and sand as possible is removed before the consolidation material is injected.
) can be easily and forcefully injected into the vicinity of the tip of the cylindrical body with a comparatively lower pressure. Place the discharge tool (2) into the caking material (
Since it is located inside the cl and is used to connect the cylinder (1) and the bulb (d), the cylinder can be firmly supported by the bulb (d) K. Therefore, the support is by the surrounding ground, the bulb (4) is by K, 0 "qli" et al. 11 "row 6
It has become possible to construct underground piles efficiently from both the spring processing and the injection of solidifying material.

Earth removal tool (2)
1, and a bottomed cylinder (4) for earth auger use, which is the same as the pile cylinder (1) and has a 6-ply or 5-concentric shape, from the tip of the pile cylinder (11). The excavated earth 74 is fixedly installed in a protruding state, and the soil removed 74 is fixedly installed in a local part of the bottom cylinder body (4) with -
