ている。When installing steel pipe piles to be used as anchors for buildings and civil engineering (i4 structures), the method of driving them using diesel engines was initially adopted; however, there are three driving methods. The noise and ground vibration are large, and although it is possible to reduce the noise by using a soundproof bar, the ground vibration is low or impossible.
Therefore, it is becoming difficult to adopt the driving method in urban areas.

As a construction method, there is a rotary press-in method in which the steel pipe pile is press-fitted into the ground while rotating.

たかなり高価なドリルシューを埋殺すことになるので、
打込杭と比べてコスト面で不利である。The shape of the drill shoe is configured to push the soil around the pile, so the contact area between the drill shoe and the soil is large, resulting in a large mouth-transfer press-fit resistance, so the press-fit speed is faster than that of a driven pile. The problem is that it's slow. Also, since you will be burying a fairly expensive drill shoe,
It is disadvantageous in terms of cost compared to driven piles.

As a result, the soil corresponding to the wall thickness of the steel cylinder 1 is pushed to the outside m++ and inside of the steel cylinder 1, and the soil inside the steel cylinder 1 enters the steel pipe pile 6 without being disturbed much. left behind. Further, since the inclined blade 4 cuts into the ground just like the thread of a wood screw cuts into wood, the rotational force of the pile is converted into a thrust force.

の効果が得られる。According to this invention, a blade having an inclined front surface 2 for pushing that extends in the vertical direction is provided at the lower part of the rounded body 1, and a blade is provided from the lower end of the inclined front surface 2 to the rear in the direction of rotation of the cylinder. The 1ζI oblique blade 4 that rises obliquely (on its own) is fixed, and the blade 5 is formed 11-1 into the annular drill.
The upper end of the drill head 5 is made of copper' [? Since the lower end of the pile 6 is attached, the narrow arc-shaped inclined blade 4 provided at the lower part of the steel cylindrical body 1 is cut into the ground, and the IA of the It is only necessary to push a small amount of soil corresponding to the surface in the horizontal direction using the inclined front surface 2 for pushing of the blade 3. Therefore, compared to conventional rotary press-fit type steel pipe piles, the same rotational force is used. When press-fitting steel pipe piles, it is recommended to increase the press-fitting speed. Also, when press-fitting with the same press-fitting material, a small rotational press-in force is required, so power costs can be reduced and small-sized rotary press-fitting is possible. Rotary press-fitting can be performed using the same press-in speed, or if the same rotary press-in force is used at the same press-in speed, larger diameter copper tubes can be repeatedly press-fitted. Furthermore, by using the cutting intrusion effect of the inclined blade 4, a part of the rotational force of the shoulder pipe pile can be converted into thrust force, and the thrust force of the pile can be increased. It is now possible to insert three piles into the ground, and the slanted blade 4 allows for
Since the ground contact area in the σ direction increases, the lead bearing capacity increases, and the lifting capacity also increases when the pulling blade acts on the steel pipe pile. In comparison, the structure is relatively □d5 ri and the material is
Since the amount of glue used is small, effects such as low cost production can be obtained.
