PRECAST REINFORCED CONCRETE PILE AND EARTH RETAINING WALL BODY CONSTRUCTION METHOD USING SAME
The present invention relates a circular precast reinforced concrete pile sequentially inserted and installed into the ground to form an earth retaining wall body, wherein the pile comprises: a guide groove that is formed on one side of the pile in a longitudinal direction; injection grooves for injecting grout that are formed in the other side of the pile or in the guide groove in the longitudinal direction; a plurality of axial rebars that is arranged inside the pile; and a spiral rebar that surrounds the plurality of axial rebars. According to the present invention, regardless of a pile coupling direction, the injection grooves are provided at intended injection positions, and thus effects wherein grouting injection methods are varied and the water barrier properties of the earth retaining wall body are excellent may be provided.
La présente invention concerne un pieu en béton armé préfabriqué circulaire inséré et installé de manière séquentielle dans le sol pour former un corps de paroi de retenue de terre, le pieu comprenant : une rainure de guidage qui est formée sur un côté du pieu dans une direction longitudinale ; des rainures d'injection destinées à injecter du coulis qui sont formées dans l'autre côté du pieu ou dans la rainure de guidage dans la direction longitudinale ; une pluralité de barres d'armature axiales qui sont disposées à l'intérieur du pieu ; et une barre d'armature en spirale qui entoure la pluralité de barres d'armature axiales. Selon la présente invention, indépendamment d'une direction d'accouplement de pieu, les rainures d'injection sont prévues à des positions d'injection voulues, offrant ainsi des effets variés en matière d'injection de coulis et d'excellentes propriétés de barrière à l'eau du corps de paroi de retenue de terre.
본 발명은 지반에 연속적으로 삽입 설치되어 흙막이 벽체를 형성하는 원형의 프리캐스트 철근콘크리트 말뚝에 있어서, 상기 말뚝의 일측면에 길이방향으로 형성되는 가이드홈; 상기 말뚝의 타측 또는 상기 가이드홈에 길이방향으로 형성되에 그라우트를 주입하기 위한 주입홈; 상기 말뚝 내부에 배근되는 복수의 축철근; 및 상기 복수의 축철근을 감싸는 나선철근;을 포함하는 프리캐스트 철근콘크리트 말뚝에 관한 것이다. 본 발명을 통해, 말뚝의 결합방향에 관계없이 주입홈이 주입하고자 하는 위치에 존재하게 되어 그라우팅 주입방법이 다양하고 흙막이 벽체의 차수성이 우수한 효과를 제공할 수 있다.
