Title (EN) LEADING PIPE AND PRESS-IN METHOD USING SAME
(FR) TUYAU D'ATTAQUE ET PROCÉDÉ D'ENFONCEMENT UTILISANT UN TEL TUYAU
(KO) 선도관체 및 이를 이용한 지중압입공법
Abstract: front page image
(EN)The present invention relates to a leading pipe (100) used in a press-in method, the leading pipe comprising: a tubular main body (110); a rotary member (120) connected to a wire saw (210) led in through a front opening part of the main body (110), and mounted on the main body (110) to rotate together with the wire saw (210). The leading pipe (100) of the present invention facilitates the press-in work of a pipe even when there is an underground obstacle, and further prevents settlement of an upper ground by accurately excavating only the ground of the position where the pipe is to be press-in.
(FR)La présente invention concerne un tuyau d'attaque (100) utilisé dans un procédé d'enfoncement, le tuyau d'attaque comprenant: un corps principal de forme tubulaire (110); un élément rotatif (120) relié à une scie à fil (210) dirigé à travers une partie d'ouverture avant du corps principal (110), et monté sur le corps principal (110) pour être entraîné en rotation conjointe avec la scie à fil (210). Le tuyau d'attaque (100) selon la présente invention facilite le travail d'enfoncement d'un tuyau même lorsqu'il y a un obstacle souterrain, et empêche également le tassement d'une masse supérieure par excavation précise uniquement du sol de la position où le tuyau doit être enfoncé.
(KO)본 발명은 지중압입공법에 사용되는 선도관체(100)에 관한 것으로서, 관 형상의 본체(110); 상기 본체(110)의 전방 트임부를 통해 인입된 와이어쏘(210)에 연결되어, 상기 와이어쏘(210)와 함께 회전하도록 상기 본체(110)에 장착된 회전부재(120);를 포함하는 것을 특징으로 하는 선도관체(100)를 제시함으로써, 지중장애물이 있더라도 관체의 압입작업을 용이하게 하도록 함과 아울러, 관체가 압입될 위치의 지반만을 정확히 굴삭하여 상부지반의 침하를 방지하도록 한다.
