Abstract

The invention relates to the field of ditch head erosion prevention, and provides a ditch head protection structure for developing erosion ditch and a construction method thereof. The ditch head protective structure with developed erosion ditch includes grit chambers, slow flow ponds, diversion pipes, stilling ponds and fixed nets arranged and connected in sequence along the water flow direction; the grit chambers and the slow flow ponds are located at The surface outside the ditch head, the stilling pool and the fixed net are arranged at the bottom of the ditch inside the ditch head, one end of the diversion pipe is connected to the slow flow pool, and the other end of the diversion pipe is connected to The stilling tank; the two sides outside the grit chamber are respectively provided with intercepting ditches for introducing runoff water into the grit chamber. The invention solves the problems of single protective measures, high treatment cost, strong land disturbance, large occupation and weak rainwater resistance ability in the existing treatment methods.

Description

technical field [0001] The invention relates to the technical field of ditch head erosion prevention and control, in particular to a ditch head protection structure with developed erosion ditch and a construction method thereof. Background technique [0002] Gullies and gullies are large-scale erosion channels formed by continuous and concentrated erosion of slope surface confluence during heavy rain or meltwater, accompanied by gravity collapse. In the black soil region of Northeast my country, the loess region of Northwest China and the red soil region of South China, the developed erosion gullies and the gully heads of collapsed hillocks are the main sources of sediment production in the basin, and the intensity of water and soil loss is extremely high. If it is not controlled in time, it will continue to occur Shuoyuan and downcut erosion, accompanied by collapse, lead to rapid expansion of gully depth and width, destroying land and restricting mechanical farming. Especi...
