【考案の詳細な説明】 （産業上の利用分野） この考案は、側壁及び拡底部に透孔を設けたコンクリー
トくいに関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a concrete pile having a through hole in a side wall and a bottom.
（従来の技術） 従来知られているコンクリートくいには何れも透孔が無

補強はできなかった。(Problems to be solved by the invention) Since there is no through hole in the conventionally known concrete pile, there is no communication between the hollow part of the pile and the inner wall of the pile hole.
There was no means other than pushing up the stabilizing liquid on the inner wall of the pit and pushing it from the bottom of the pit or injecting from the top of the pit. Therefore, in the medium excavation method, since there is no means for filling cement milk or the like between the outer wall of the pile and the inner wall of the pile hole, the bottom drilling pier cannot be used. Further, since the inner wall of the pile and the hollow portion of the pile cannot be connected, even if cement hollow was filled into the hollow portion of the pile, the outer wall of the pile could not be reinforced by this.

強できるようにしたのである。(Means for Solving the Problems) However, according to the present invention, since the lateral wall of the shaft portion is provided with a plurality of lateral through holes and the lateral wall of the expanded bottom portion is provided with a longitudinal through hole, the stake is buried in the pierced hole. When you do, firmly connect the inside and outside of the pile,
Alternatively, the gap between the outer wall of the pile and the inner wall of the pile hole can be filled with cement milk or the like without leakage so that the bearing capacity of the pile can be further enhanced.

とを特徴とするコンクリートくいである。That is, according to this invention, a plurality of lateral through holes are provided in a side wall of the hollow piling body having a shaft portion and a bottom expanding portion, and a plurality of vertical through holes are provided in a side wall of the bottom expanding portion. It is a concrete pile that is characterized by that.

ができる。Through holes provided in the pile body are, for example, 4 to 1 for each 1m of pile length.
Staggered at 0 places and a diameter of 2 cm to 10 cm. This through-hole should be accurately drilled in a specified number of places by placing a synthetic resin pipe or metal pipe of a specified diameter in an appropriate place in the mold during centrifugal molding of concrete piles. You can

Further, when the cement milk hardens, the inside and outside can be integrated.
（実施例） 図面に基づき、この考案の実施例を説明する。(Example) The Example of this invention is described based on drawing.
軸部１の下部に拡底部５を連設すると共に、上下全長に

３の軸部１側壁へ透孔６、６を半径方向で放射状に、軸
方向で一定間隔かつ千鳥状に設ける（第１図、第２
図）。In a pile body 3 having a hollow portion 2 extending over the entire vertical length, a bottom portion 5 is continuously provided below the shaft portion 1, and through holes 6, 6 are radially formed in the sidewall of the shaft portion 1 of the pile body 3 in the radial direction. , Staggered in the axial direction (Figs. 1 and 2)
Figure).
また、くい本体３の下部の拡底部５にも縦方向（軸方
向）の透孔７、７を設ける（第１図、第３図）。以上の
ようにして、コンクリートくい４を構成する（第１
図）。Further, through holes 7, 7 in the vertical direction (axial direction) are also provided in the expanded bottom portion 5 at the bottom of the pile body 3 (FIGS. 1 and 3). The concrete pile 4 is configured as described above (first
Figure).

枠内へ支持すればよいことになる。尤もこの場合には、
管体８、９の両端部に栓をして、セメントミルクなどの
流入を防ぐことが好ましい。In the figure, 8 and 9 are tube bodies made of synthetic resin tubes or iron tubes, and any of the through holes 6 and 7 are formed by the tube bodies 8 and 9. In order to provide the through holes 6 and 7, it is sufficient to support the tubular body 8 of a predetermined length (same as the wall thickness) and the tubular body 9 of a predetermined length in the mold during centrifugal molding of the pile. . But in this case,
It is preferable to plug both ends of the pipes 8 and 9 to prevent the inflow of cement milk or the like.

複合くいができる。When the concrete pile 4 is inserted into the pile hole 10, since the through holes 6 and 7 are connected and opened in the gap 11 between the outer wall 4a of the concrete pile 4 and the inner wall of the pile hole 10, the pile hole is formed. The bottom and the hollow part of the pile communicate with the gap 11. Therefore, if the hollow portion 4b is pressure-filled with cement milk, the cement milk flows into the gap portion 11, and the hollow portion 4b and the gap portion 11 are integrated to form a strong composite pile.

Therefore, if the hollow part is pressurized and filled with cement milk, it can easily flow into the gap between the outer wall of the pile and the cement milk can be filled without leaking, and the gap between the inner wall of the pile hole and the outer wall of the concrete pile can be filled. Since it is possible to construct a composite pile that integrates the hollow part of the concrete pile, the bottom of the pile, and the concrete pile, it is possible to increase the bearing capacity of the pile.
