COMPOSITE CORRUGATED PIPE ASSEMBLY PREVENTING WATER FROM LEAKING THEREFROM

Disclosed is a composite corrugated pipe assembly which prevents water from leaking therefrom. The disclosed composite corrugated pipe assembly, which prevents water from leaking therefrom, comprises: a corrugated steel pipe (10) which is obtained by forming a steel sheet into a circular pipe shape and has a corrugation comprising convex ridges and concave grooves formed thereon in the thickness direction, the corrugation being spirally formed in the longitudinal direction; an inner pipe (20) which is obtained by forming a soft material into a circular pipe shape and is inserted into the corrugated steel pipe (10); and a filler (30) which is filled between the inner surface of the corrugated steel pipe (10) and the outer surface of the inner pipe (20) to integrate the corrugated steel pipe (10) and the inner pipe (20) with each other, wherein the inner surface of the inner pipe (20) is formed as a smooth surface so as to minimize flow resistance. L'invention concerne un ensemble tuyau ondulé composite qui empêche les fuites d'eau. L'ensemble tuyau ondulé composite de l'invention, qui empêche les fuites d'eau, comprend : un tuyau en acier ondulé (10) qui est obtenu en donnant à une tôle d'acier une forme de tuyau circulaire et comporte une ondulation comprenant des crêtes convexes et des rainures concaves formées sur celui-ci dans la direction de l'épaisseur, l'ondulation étant formée en spirale dans la direction longitudinale ; un tuyau intérieur (20) qui est obtenu en donnant à un matériau souple une forme de tuyau circulaire et est inséré dans le tuyau en acier ondulé (10) ; et une garniture (30) qui remplit l'espace entre la surface intérieure du tuyau en acier ondulé (10) et la surface extérieure du tuyau intérieur (20) pour solidariser le tuyau en acier ondulé (10) et le tuyau intérieur (20) l'un à l'autre, la surface intérieure du tuyau intérieur (20) étant de la forme d'une surface lisse de façon à réduire au minimum la résistance à l'écoulement. 누수가 방지되는 파형복합관 조립체가 개시된다. 개시된 누수가 방지되는 파형복합관 조립체는, 강판으로 원형 파이프 형상으로 형성되되, 두께 방향의 볼록부와 오목홈으로 이뤄진 파형이 길이방향에 대해 나선형으로 형성된 파형강관(10); 연성 재질로 원형 파이프 형상으로 형성되어 상기 파형강관(10) 내부에 삽입되는 내부관(20); 및 상기 파형강관(10)의 내측면과 내부관(20)의 외측면 사이에 충진되어 파형강관(10)과 내부관(20)을 일체화하는 충진재(30);를 포함하며, 상기 내부관(20)의 내측면은 매끈한 표면으로 형성되어 유동저항을 최소화하는 것을 특징으로 한다.
