More Information
Summary:The present invention relates to an underground common duct using a corrugated steel pipe and a construction method thereof, which can prevent damage to facilities by securing water tightness. Corrugated steel pipes are arranged in an underground burying space while opened connection ends of the corrugated steel pipes face each other. Diaphragms have an opened middle portion and a flat lower end and are joined around the connection ends of the corrugated steel pipes. Gaskets are arranged between the diaphragms and maintain water tightness between the diaphragms as the diaphragms are coupled. Main post apparatuses are arranged along the inside of the corrugated steel pipes to support the corrugated steel pipes. Each main post apparatus includes a lower main post erected while the lower end of the lower main post is fixed on the bottom in the corrugated steel pipes, and an upper main post erected while the upper end of the upper main post is fixed on the ceiling in the corrugated steel pipes, and coupled to be lifted with respect to the lower main post by inserting the lower end portion of the upper main post into the upper end portion of the lower main post. Trays are coupled to the main post apparatuses to load facilities thereon. 본 발명은 파형강관을 이용한 지하공동구 및 그 시공방법에 관한 것이다. 파형강관들은 개구된 연결단끼리 상호 마주한 상태로 지하 매설 공간에 배열된다. 격판들은 중앙이 개구되고 하단이 편평한 형태로 각각 이루어져 파형강관들의 연결단 주변을 따라 각각 접합된다. 개스킷들은 격판들 사이에 각각 배치된 상태로 격판들의 결합에 따라 격판들 간에 수밀을 유지시킨다. 메인 포스트 기구들은 파형강관들의 내부를 따라 배열되어 파형강관들을 지지하는 것으로, 하단이 파형강관의 내부 바닥에 고정된 상태로 세워진 하부 메인 포스트와, 상단이 파형강관의 내부 천장에 고정된 상태로 세워지고 하단 부위가 하부 메인 포스트의 상단 부위에 끼워져 하부 메인 포스트에 대해 승강 가능하게 결합되는 상부 메인 포스트를 각각 구비한다. 트레이들은 메인 포스트 기구들에 결합되어 시설물을 탑재한다.
