Zusammenfassung:	The present invention relates to an impeded drainage device for an underground structure, the device comprising: a drainage body which is inserted into a bored hole (core hole) formed in the bottom surface of an underground structure, and which has a water-permeable part provided in an inner space part, has a valve mounting part provided on the water-permeable part, and has a filter mounting part provided on the valve mounting part; a leakage prevention pad for covering the gap between the upper portion of the drainage body and the bored hole provided in the bottom surface of the underground structure; a leakage prevention cover provided on the leakage prevention pad such that the leakage prevention pad is pressed toward the bottom surface of the underground structure by means of anchor bolts; a backflow prevention valve inserted into the valve mounting part to prevent backflow; and a filter inserted into the filter mounting part to remove foreign material. La présente invention concerne un dispositif de drainage entravé pour une structure souterraine. Ledit dispositif comprend : un corps de drainage qui est inséré dans un trou foré (trou central) formé dans la surface inférieure d'une structure souterraine, et qui présente une partie perméable à l'eau disposée dans une partie d'espace interne, une partie de montage de soupape disposée sur la partie perméable à l'eau, et une partie de montage de filtre disposée sur la partie de montage de soupape; un tampon de prévention de fuite pour recouvrir l'espace entre la partie supérieure du corps de drainage et le trou foré disposé dans la surface inférieure de la structure souterraine; un couvercle de prévention de fuite disposé sur le tampon de prévention de fuite de telle sorte que le tampon de prévention de fuite est pressé vers la surface inférieure de la structure souterraine au moyen de boulons d'ancrage; une soupape de prévention de reflux insérée dans la partie de montage de soupape pour empêcher un reflux; et un filtre inséré dans la partie de montage de filtre pour éliminer un matériau étranger. 본 발명은 지하구조물용 지연배수장치에 관한 것으로서, 지하구조물의 바닥면에 천공된 천공홀(코어홀)에 삽입되는 것으로, 내부 공간부에 투수부가 구비되며, 상기 투수부의 상부에 밸브 안착부가 구비되고, 상기 밸브 안착부의 상부에는 필터 안착부가 구비된 배수 몸체, 상기 배수 몸체의 상부와 상기 지하구조물의 바닥면에 구비된 천공홀 사이의 틈을 덮도록 구비된 누수방지 패드, 상기 누수방지 패드의 상부로 앵커 볼트에 의하여 상기 누수방지 패드가 상기 지하구조물의 바닥면을 향하여 가압되게 구비된 누수방지 덮개, 상기 밸브 안착부에 삽입되어 역류를 방지하는 역류 방지밸브, 및 상기 필터 안착부에 삽입되어 이물질을 제거하는 필터를 포함한다.
