CONSTRUCTION METHOD FOR COVERED CONDUIT

PROBLEM TO BE SOLVED: To provide a construction method for a covered conduit capable of letting cross sectional gradient of a road paved surface agree with an upper face of the covered conduit easily and preventing flow on one side in a flowing water hole in the covered conduit easily by tilting an upper face of a foundation panel properly in the direction of width. SOLUTION: In this construction method for the covered conduit 3, the covered conduit 3 is constructed in an end part 2 in the direction of cross section of a paved road 1. A bottom panel 6 whose gradient of an upper face 6a is substantially equal to the cross sectional gradient of the road paved surface 1a is constructed in a bottom part 4a in a recessed part 4 in which the covered conduit 3 is constructed. The covered conduit 3 is provided on the upper face 6a of the bottom panel 6 in such a way that its upper face 3a is substantially flush with the road paved surface 1a. COPYRIGHT: (C)2003,JPO
