Triangular Water Measuring Weir
Abstract A triangular water measuring weir, which comprises a water collecting weir groove, a water gauge and a weir plate. The water collecting weir groove is composed of two parallel weir bodies, and the cross section of the water collecting weir groove is a rectangular groove. A water gauge and a weir plate are provided at the inner side of the tail end of the water collecting weir groove, which is characterized in that, a splayed cut-off wall is provided at the head end of the water collecting weir groove, and the splayed cut-off wall encloses a sedimentation tank; the small mouth end of the splayed cut-off wall is butted with the two weir bodies of the water collecting weir groove; both the water collecting weir groove and the splayed cut-off wall are made of C35 concrete, and the foundation is made of C35 fine-grained concrete masonry; a V-shaped weir is provided in the middle of the top end of the weir plate. The triangular water measuring weir of rubble concrete of the invention has simple structure, convenient production, small floor area and filling amount of rubble concrete and low engineering cost; and the use of weir head can accurately measure the flow rate, with high measurement precision and accuracy, convenient and labor-saving operation and strong ability to resist mountain torrent erosion.
