Abstract

The invention relates to the field of prevention and control of gully head erosion, and provides a gully head protection structure for developing an erosion gully and a construction method thereof. The gully head protection structure for developing the erosion gully comprises a grit chamber, a slow flow tank, a draft tube, a stilling basin and a fixing screen which are arranged in sequence and arein communication in sequence along the water flow direction, wherein the grit chamber and the slow flow tank are arranged on the surface outside a gully head; the stilling basin and the fixing screenare arranged at the gully bottom in the gully head; one end of the draft tube is in communication with the slow flow tank; the other end of the draft tube is in communication with the stilling basin;and the two sides outside the grit chamber are provided with interception gullies for introducing runoff water into the grit chamber respectively. Through the adoption of the gully head protection structure, the problems of single prevention measure, relatively high treatment cost, high land disturbance, great occupation and relatively weak rain flood resistance in an existing treatment method are solved.

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...
