Triangular measurement weir
The invention discloses a triangular measurement weir. The triangular measurement weir comprises a catchment weir groove, a water gauge and a weir plate, wherein the catchment weir groove is composed of two parallel weir bodies, the section of the catchment weir groove is a rectangular groove, and the water gauge and the weir plate are arranged at the inner side of the tail end of the catchment weir groove. The triangular measurement weir is characterized in that a splayed key wall is arranged at the head end of the catchment weir groove, and surrounds a sedimentation pool; a small-opening end of the splayed key wall is in butt joint with two weir bodies of the catchment weir groove; the catchment weir groove and the splayed key wall are both made from C35 concrete, and the foundations thereof are made from C35 fine-grain concrete masonries; and a V-shaped weir opening is formed in the middle part of the top end of the weir plate. The triangular measurement weir made from rubble concrete, which is disclosed by the invention is simple in structure, convenient to produce, small in floor area, low in rubble concrete filling volume, and low in engineering cost; and moreover, the triangular measurement weir is capable of accurately measuring a flow by virtue of a weir head, high in measurement precision and accuracy, convenient and labour-saving in operation, and high in mountain torrent scouring capacity.
