This Architectural Drawing is AutoCAD 2d drawing of Pier type 7 For canal type in AutoCAD, Dwg files. A canal outlet is a structure built at the head of the tertiary unit to deliver water from the canal to the field watercourses. Water is taken from the field watercourses for irrigating individual fields. A pier is a raised structure that rises above a body of water and usually juts out from its shore, typically supported by piles or pillars, and provides above-water access to offshore areas. Frequent pier uses include fishing, boat docking and access for both passengers and cargo, and oceanside recreation. For more details and information dowmnload the drawing file.
