Concrete Overflow Drain Details With 0.60 m Channel Section.

This drawing presents a concrete overflow drain detail with channel section prepared in AutoCAD files for water discharge and drainage structure construction. The overflow system shows the structural configuration used to control excess water flow at headwall structures. The section illustrates a curved overflow channel with a width of 0.60 m that directs water toward the discharge outlet. A perforated plate is positioned at the overflow inlet to regulate water entry and prevent debris from entering the drainage system. The drawing also identifies the overflow tray made of wood, which guides water into the drainage channel before it reaches the concrete discharge pipe.
