Title:
DRAINAGE STRUCTURE
Document Type and Number:
Japanese Patent JP2788617
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To prevent the infiltration of rainwater into a habitable room and the generation of the leaking of rain in the habitable room in an underfloor section even when a drain inlet is closed by refuse clogging, etc.
SOLUTION: Two drain inlets 3 are formed to the base of a horizontal gutter 1, drain cylinders 7, in which the height of water-receiving ports 5 differs, are connected to these drain inlets 3 respectively, and secondary drain cylinders 7, in which the water-receiving ports 5 are placed at high positions, consist of drain cylinder bodies 8 erected from the drain inlets 3 and shade-shaped eaves 9 having diameters larger than the diameters of the drain cylinder bodies 8 and covering the whole circumferences of the upper edges of the drain cylinder bodies 8. Consequently, since the two drain inlets 3 are formed to the base of the horizontal gutter 1 and the drain cylinders 7, in which the height of the water-receiving ports 5 differs, are joined to these drain inlets 3 respectively, rainwater collected in the horizontal gutter 1 can be drained from the secondary drain cylinders 7, in which the water-receiving ports 5 are placed at high positions, when the drain cylinders, in which the water-receiving ports are low, are closed by refuse clogging, etc. Accordingly, the infiltration of rainwater into a habitable room and the generation of the leaking of rain in a habitable room in an underfloor section can be prevented.
