【発明の詳細な説明】
（産業上の利用分野）
本発明は振動を伴わない小径杭の施工法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for constructing small diameter piles without vibration.
（従来の技術）
従来において杭の施工には振動を伴うことか多く改良の
余地かあった。(Prior art) In the past, pile construction often involved vibration, and there was room for improvement.
（発明か解決しようとする課題）
本発明は以上の従来の課題を解決し振動を伴わず施工出
来る小径杭の施工法の提供を目的とする。(Problems to be Solved by the Invention) The present invention aims to solve the above-mentioned conventional problems and provide a method for constructing small-diameter piles that can be constructed without vibration.
（課題を解決するための手段）
本発明は以上の目的達成のために
１、外管か嵌着された状態で土中に小径の杭芯を圧入し
た後外管を引き抜いてモルタル、セメントミルク等を杭
芯の孔から土中に浸透させる小径杭の施工法
を提案するものである。(Means for Solving the Problems) In order to achieve the above-mentioned objects, the present invention includes: 1. After press-fitting a small-diameter pile core into the soil with the outer tube fitted, the outer tube is pulled out and mortar and cement milk are poured into the soil. This paper proposes a construction method for small-diameter piles in which the materials penetrate into the soil through holes in the pile core.
（作用）
（１）本発明の施工法は特に小径の杭芯を用いるため施
工時に振動を伴わない。(Function) (1) Since the construction method of the present invention uses a particularly small diameter pile core, there is no vibration during construction.
（２）本発明の施工法は特に圧入時には外管を用いるた
め土か杭芯内に入ることはない。(2) Since the construction method of the present invention uses an outer pipe especially during press-fitting, soil does not enter the pile core.
（実施例）
以下本発明の小径杭の施工法を図面に示す実施例に従い
説明する。(Example) The method for constructing a small diameter pile of the present invention will be described below according to an example shown in the drawings.
第１図は本発明の施工法に用いる小径杭の杭芯を示し、
該杭芯（２）は底板（３）によりその底面か閉し・られ
及Ｕその側壁に複数個の孔（４）を有するバイブである
。Figure 1 shows the pile core of a small diameter pile used in the construction method of the present invention,
The pile core (2) is a vibrator whose bottom surface is closed by a bottom plate (3) and has a plurality of holes (4) in its side wall.
該杭芯（２〉の外周には外管（６）が嵌着されて孔（４
）から土か杭芯（２）内に入ることを防止している。An outer tube (6) is fitted to the outer periphery of the pile core (2) and the hole (4)
) to prevent soil from entering the pile core (2).
すなわち杭芯（２）は例えば６０＋＋＋ｅ直径の小径の
パイプが用いられるため土中への圧入は振動を伴わず圧
力で挿入すればよく極めて容易である″。That is, since the pile core (2) is a small-diameter pipe with a diameter of, for example, 60+++e, it is extremely easy to press it into the soil by applying pressure without vibration.
この土中への圧入時に外管（６）かあるため孔（４）か
ら土が杭芯（２）内に入ることが防止される。During this press-fitting into the soil, the presence of the outer pipe (6) prevents soil from entering the pile core (2) through the hole (4).
杭芯（２）の土中への圧入液外管（６）が土中から引き
抜かれる。The outer pipe (6) of the liquid injected into the soil of the pile core (2) is pulled out from the soil.
次に第２図に示す様に杭芯（２）の上端にキャップ（５
）を装着しモルタル、セメントミルク等を杭芯（２）内
に送り込む。Next, as shown in Figure 2, attach the cap (5) to the top of the pile core (2).
) and feed mortar, cement milk, etc. into the pile core (2).
これによりモルタル、セメントミルク等は杭芯（２）の
孔（４）から土中に浸透し第３図に示す様に浸透部（７
）を形成し小径杭の施工は完了する。As a result, mortar, cement milk, etc. permeate into the soil through the hole (4) of the pile core (2), and as shown in Fig.
) and the construction of small diameter piles is completed.
（発明の効果）
本発明の小径杭の施工法の実施例は以上の通りでありそ
の効果を次に列記する。(Effects of the Invention) The embodiments of the small diameter pile construction method of the present invention are as described above, and the effects thereof are listed below.
（］）本発明の施工法は特に小径の杭芯を用いるため施
工時に振動を伴わない。(]) The construction method of the present invention uses particularly small-diameter pile cores, so there is no vibration during construction.
（２）本発明の施工法は特に圧入時には外管を用いるた
め土か杭芯内に入ることはない。(2) Since the construction method of the present invention uses an outer pipe especially during press-fitting, soil does not enter the pile core.
