い。The drainage hole is provided to the invention Problem to be Solved] Conventional gutter upper, intended to underdrain inset lid is usually an inner diameter 3
For 0 to 40 cm, use a lid plate with a thickness of about 10 cm
The gutter body matches the lid receiving small step to store the lid plate and the lid thickness
The upper part of the side wall which rises from the lid receiving step and forms a pavement stop
In this case, the thickness of the rising part is required
It is restricted to a minimum. Pavement stop
The drain hole to be drilled corresponds to the drainage pavement thickness of 5-6cm and the side wall
It is installed at almost the middle height of the upper rise, so from the side wall
Since the clogging of the drainage through the gap between the lid plate above the lid receiving step and the inside of the gutter and discharging to the gutter cannot be expected, the drainage function cannot be expected, and the maintenance is not sufficient.

い側溝暗渠を得ることを目的としている。The present invention relates to a method of installing a culvert in a ditch on a falling side as a vertical drainage pipe along a pavement side end to treat rainwater permeated into a drainable pavement and road surface water that does not permeate.
Infiltration water is discharged along the length of the road into the gutter without clogging in the shortest distance, and at the same time, surface water that does not permeate falls down from the upper surface and drains, and sufficient drainage continues along the road even if the surface water becomes heavy due to heavy rain. The purpose is to obtain a gutter culvert that has the capacity and is less likely to cause flooding on the road surface.
