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: referring to Fig. 5, this load-reducing back-wave flood control embankment structure comprises a section of main arc line segment BC in the section line of the flood control embankment facing the water side, and the main arc line segment BC consists of a section Or a plurality of arcs or curves, the centers of curvature of the arcs or curves are on the water side of the main arc segment BC, and the lower end of the arc segment passes through a section of load-reducing reverse bending arc Section CD connects the slope line at the bottom of the flood control embankment, and the said lower recurved arc segment CD is composed of one or more circular arcs or a curve, and all the centers of curvature of said circular arcs or curves are at On the backwater side of the line segment CD, the said down-bending arc line segment CD is located at the flood water once in the design year. The once-in-a-lifetime flood level in the desi...

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 control dike structure, in particular to a load-reducing and return-wave flood control dike 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] The embankment is shown in Figure 1. The section of the embankment is designed as a trapezoid with oblique lines on both sides. [0005] When the flood hits the embankment, at the moment of impact, the flood wi...
