Combined energy dissipator

Abstract

The invention discloses a combined energy dissipator. The combined energy dissipator comprises a plurality of energy dissipator bodies which are arranged side by side, and each energy dissipator bodycomprises an overflow dam, energy-dissipation steps, flaring piers and a stilling pool, wherein the step profile of each energy-dissipation steps is shaped like the lower part of an ellipse, the upperend of the energy-dissipation steps is connected with the top of the overflow dam, the lower end of the energy-dissipation steps is connected with the front ends of the flaring piers, and the rear ends of the flaring piers are connected with the stilling pool through inverted arc sections. Gate piers are arranged between the energy dissipator bodies, and the gate piers keep extending to the rearends of the flaring piers from the front ends of the overflow dams. By means of the combined energy dissipator, the lengths between the energy-dissipation steps and the stilling pool can be effectively reduced, the engineering quantity is reduced, the engineering cost is reduced, and energy loss can be efficiently reduced.

Description

technical field [0001] The invention belongs to the technical field of flood discharge and energy dissipation for water conservancy and hydropower projects, and in particular relates to an energy dissipation tool. Background technique [0002] The problem of energy discharge is often a major and complex scientific and technical problem in the design of large-scale water conservancy and hydropower projects. It requires comprehensive consideration of the relationship and rational layout of water-retaining buildings, water-discharging buildings and building-making buildings. And according to the topography, geology and hydrological conditions of the dam site, the form of the discharge structure and the safe and reliable energy dissipation method are reasonably selected. The traditional energy dissipation methods commonly used mainly include wide tail piers, energy dissipation steps, stilling pools, etc. or a combination thereof. Two combinations, but the traditional energy diss...

Problems solved by technology

[0002] The problem of energy discharge is often a major and complex scientific and technical problem in the design of large-scale water conservancy and hydropower projects. It requires comprehensive consideration of the relationship and rational layout of water-retaining buildings, water-discharging buildings and building-making buildings. And according to the topography, geology and hydrological conditions of the dam site, the form of the discharge structure and the safe and reliable energy dissipation method are reasonably selected. The traditional energy dissipation methods commonly used mainly include wide tail piers, energy dissipation steps, stilling pools, etc. or a combination thereof. Two combinations, but the traditional energy dissipation method of single or pairwise combination requires the energy dissipation worker to be too large, which has the disadvantages of high cost, large amount of engineering, and low energy dissipation efficiency
