Abstract
PURPOSE: To increase durability by arranging a spacer to vary smoothly the cross sectional shape of a cutoff member in the inside of a cutoff member perpendicular to the axis of a covered conduit between the corners of the covered conduit and the cutoff member and a sealing compound between the spacer and the covered conduit. CONSTITUTION: A spacer 18 conforming to the corners of a box culvert 11 is arranged between the corners of the box culvert 11 forming a covered conduit and a flexible joint 14. The spacer 18 varies smoothly the cross sectional shape of the flexible joint 14 in the side perpendicular to the axis of the box culvert 11. In addition, a sealing compound 16 made up of a water expandable rubber is arranged between the spacer 18 and the box culvert 11, thereby eliminating the need for local great pressing bend in the corners of a covered conduit or open conduit and controlling sufficiently an occurrence of a defect and an abnormal deformation.
