A Dam Foundation That Can Resist Extraordinary Floods

Abstract

A novel dam foundation capable of resisting a catastrophic flood is characterized by comprising a dam foundation body, wherein a water inlet is formed in the inner end of the dam foundation body; a water outlet is formed in the outer end of the dam foundation body; the length of the water inlet is designed to be m; the length of the water outlet is designed to be n; the length m of the water inlet is 2-10 times of the length n of the water outlet; the dam foundation body is divided into a front part and a back part by a middle boundary line between the water inlet and the water outlet; an automatic storage and discharge board is arranged on the middle boundary line; the water inlet of the dam foundation body consists of three rectangles which are connected together; the water inlet is inclined; the included angle between the water inlet and the horizontal plane is 40-50 degrees; the water outlet consists of two rectangles; grasping nails are installed on the two sides of the water inlet; the dam foundation body is fixed by the grasping nails, so that the dam foundation is more firm.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a novel dam foundation capable of resisting extreme floods. Background technique [0002] It is reported that hundreds of dam foundations (reservoirs, lakes, etc. above small and medium-sized) have been washed away (some are almost uprooted) due to severe floods in the country's water conservancy projects in the past 20 years. People's lives and properties have caused immeasurable losses. According to relevant materials and news media reports, the main reasons for the heavy losses are: 1) more than 60% of the dam foundations are not scientifically designed and the structure is not reasonable enough; 3) 5% belong to irresistible catastrophic disasters, such as earthquakes, mudslides, landslides, etc. [0003] For example, on October 26, 2011, I disclosed an automatic storage and discharge device suitable for dams, the publication number being CN202273213U, ...
