Problems solved by technology

Therefore, for this type of flood control embankment, when the flood velocity is high, due to the action of centrifugal force, the water will rush out from point B of the "sharp edge", and the direction of the flood rushing out will be against the water, which will not cause the flood to overflow , but due to the large centrifugal force, the "sharp edge" B has to bear a large force, resulting in the destruction of the "sharp edge"

Embodiment Construction

[0031] A preferred embodiment of the present invention is: see Figure 5 , the structure of the load-reducing and returning-wave flood control embankment includes a section of main arc BC in the section of the flood control embankment facing the water side, and the main arc section BC is composed of one or several arcs or curves. All the curvature centers of the arcs or curves are on the water-facing side of the main arc segment, and the lower end of the arc segment is connected to the slope line at the lower part of the flood embankment through a load-reducing anti-bending arc segment. The recurved arc segment is composed of one or more circular arcs or a curve, and all the curvature centers of the said garden arcs or curves are on the backwater side of the lower recurved arc segment, and the said lower recurved arc The section is located at the place where the flood water occurs once in the design year. The once-in-a-lifetime flood level in the design period is the flood le...

Abstract

A load-decreasing, wave-reflecting and antiflood dyke features that its cross-section has an arc segment at its one side close to water and the lower end of said arc segment is linked with the lower slope of said dyke via a reverse arc segment for decreasing load. Said arc segment is composed of one or more arcs or curves whose curvature center is at the side close to water. Said load-decreasing reverse arc segment is composed of one or more arcs or one curve whose curvature center is at the side far from water.

Description

technical field [0001] The invention relates to a flood protection embankment structure. In particular, the utility model relates to a load-reducing and wave-returning flood protection embankment structure. technical background [0002] In recent years, the state has also stepped up its efforts in the regulation of large rivers and the construction of urban flood dykes. The construction of large rivers, large rivers and urban flood dykes to avoid and reduce the loss of people's lives and property and national production caused by flood disasters is an important aspect of social development. It is also the urgent desire and demand of the people. [0003] The construction of flood control levee usually requires that the levee can resist the catastrophic flood once in 50, 60 or even 100 years. conventional [0004] embankment such as figure 1 As shown, the cross section of the embankment is designed as a trapezoid with oblique lines on both sides. [0005] When the flood h...
