Gully head protection structure for developing erosion gully and construction method thereof
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.
本发明涉及沟头侵蚀防治领域，提供发育侵蚀沟的沟头防护结构及其施工方法。该发育侵蚀沟的沟头防护结构包括沿水流方向依次设置且连通的沉砂池、缓流池、导流管、消力池和固定网；所述沉砂池和所述缓流池设于沟头外的地表，所述消力池和所述固定网设于所述沟头内的沟底，所述导流管的一端连通所述缓流池，所述导流管的另一端连通所述消力池；所述沉砂池外的两侧分别设有用于将径流水引入所述沉砂池的截水沟。本发明解决了现有治理方式存在的防护措施单一，治理成本较高，对土地扰动强、占用多，雨洪抗御能力较弱的问题。
