Broken line type energy dissipation and drainage channel for power transmission line
The broken line type energy dissipation drainage channel for the power transmission line comprises a drainage channel body, a pebble bed is laid on the surface of the drainage channel body, and a cement mortar layer is arranged on the surface of the pebble bed; a water outlet at the end part of the drainage channel extends outwards to form a water outlet section, and an inclined apron ramp for draining water is arranged behind the water outlet; a water outlet of the drainage channel is provided with a weir, the weir is of a triangular structure connected end to end, and the axis of the top of the weir is in a continuous broken line shape; the flow velocity of water is reduced, the drainage front edge of the drainage channel is increased, the scouring effect of hydraulic power on a soil body and the drainage channel structure is reduced, and water and soil loss is avoided.
本发明一种折线式输电线路用消能排水渠，包括排水渠，所述排水渠表面铺设有卵石层，卵石层表面设置有水泥砂浆层；所述排水渠端部的出水口处向外延伸有出水段，出水口后设置有用于泄水倾斜的散水坡道；所述排水渠出水口处设置有水堰，水堰形状为首尾相连的三角形结构，水堰顶部轴线形状为连续的折线；本发明降低了水的流速，增加了排水渠的泄水前沿，减小了水力对土体和排水渠结构本身的冲刷作用，避免水土流失。
