摘要： PROBLEM TO BE SOLVED: To facilitate not only the manufacturing of a unit side drain body having a cross-section equal to or larger than the unit side drain body forming a plurality of stream outlets in the upper side but also the construction in accordance with conditions of a site and to provide a drain cover of the side drain equipped with the steam outlets capable of reducing thereby manufacturing cost and construction cost of the side drain. SOLUTION: Since stream outlets 5 connected to a channel 7 in a side drain are formed in at least the end sides of a boundary block 4, it is safe also for a walker and, at the same time, fluid such as rainwater, etc., flowing down on the road surface can be smoothly collected. In respect of manufacturing and construction work, a conventional core is not required, the steam outlets 5 can be easily molded because of a narrow molding area, and manufacturing cost or construction cost of the side drain can be reduced since construction in accordance with conditions of a site is facilitated.

摘要： PROBLEM TO BE SOLVED: To provide a side ditch with running-water ports, in which the manufacturing cost of the side ditch can be reduced by easily manufacturing the side ditch, in which a plurality of the running-water ports are formed to an upper side face, and a ditch cover for the side ditch. SOLUTION: Since running-water ports 4 are formed at the end section of at least a unit side ditch body 1, the side ditch 1 is molded easily because cores excepting a core for the running-water port 4 for forming the running-water port 4 in an intermediate section as seen in conventional devices are made unnecessary. Dangerousness such as the falling of a leg can be avoided even to a pedestrian because the running-water ports 4 are formed to side faces, and the efficiency of water collection is improved because a fluid such as rainwater flowing down on a road surface can be collected.

摘要： PROBLEM TO BE SOLVED: To improve water collectivity of a collecting side ditch, and cleaning workability of a culvert-type side ditch linearly connected to the collecting side ditch, by attaching, in one body, a curb structure on an upper surface of a grating openably attached to the upper opening of a collecting side ditch, via attaching tools. SOLUTION: Metal fittings 8 are set on the rear surface of a grating G beforehand in a manner corresponding to through holes of seating portions 5a, 5b of a curb structure 4 and aligning with curbs 2b, 3b of respective culvert- type side ditches 2, 3. Then, the curb structure 4 is mounted on the upper surface of the grating G which is adjusted such that the through holes of the seating portions 5a, 5b are opposed to through holes of the metal fittings 8. Then, a connecting bolt 9 is inserted from each through hole of the metal fitting 8 and through each through hole of the seating portion 5a, 5b. Next, the front end of the bolt 9 is inserted into a flat washer 11 and screwed into a nut 10. When the side ditches 2, 3 are cleaned, the grating G is rotated via a hinge 7, thereby carrying out cleaning through an opening 1b. Thus, cleaning workability can be improved.
