Flood discharge, energy dissipation, grit sedimentation and sand discharge integrated multifunctional structure pool

Abstract

The invention relates to a flood discharge, energy dissipation, grit sedimentation and sand discharge integrated multifunctional structure pool. The flood discharge, energy dissipation, grit sedimentation and sand discharge integrated multifunctional structure pool comprises a bottom plate, a first wall, a second wall, a third wall and a fourth wall, the first wall, the second wall, the third walland the fourth wall are arranged side by side on the bottom plate, the first wall and the second wall are perpendicular to the third wall and the fourth wall, a water inlet is formed in the first wall, a water outlet and a flushing opening are formed in the second wall, the water outlet and the water inlet are correspondingly distributed, and the flushing opening is located at the upper portion of one side of the bottom plate; and two trapezoidal baffles are arranged side by side at the position of the flushing opening in the inner side of the second wall, and a flushing gate capable of beingopened and closed is hinged between the two trapezoidal baffles in a matched manner. The flood discharge, energy dissipation, grit sedimentation and sand discharge integrated multifunctional structure pool well solves the problems that a baffle structure applied to instant high flow rate, large-flow along-way line longitudinal slope drainage projects of a pluvial region at present has energy dissipation, the using effect is greatly reduced, high-speed water flow scours and abrades the structure pool or is splashed out of the structure pool, and surrounding backfill and surrounding building stability and the like are affected.

Description

technical field [0001] The invention relates to the field of water transport and energy dissipation in channels, tunnels, and water conservancy and hydropower projects, in particular to a multifunctional structural pool integrating flood discharge, energy dissipation, sand settling, and sand discharge. Background technique [0002] Water diversion projects generally exist in water conservancy and mining fields. When water diversion projects are located in mountainous areas, where the terrain is relatively steep and the water sources are concentrated, in order to avoid damage to the building structure caused by excessive water diversion speed and reduce the threat of scouring to the outside of the structure, the actual During the construction process, stilling pools are generally added to the water inlet and outlet to reduce the flow rate of water diversion. Most of the existing stilling basins use "open concrete stilling basin with multiple inlets and single outlet", "rectan...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above problems, the object of the present invention is to provide a multi-functional structure pool integrating flood discharge, energy dissipation, sand settling and sand discharge, which better solves the problem of instantaneous high flow velocity, large flow, and along the The stilling structure pool of the steep longitudinal slope drainage project of the route line has energy dissipation in the stilling structure pool, and there are different degrees of scour wear and tear on the bottom plate and side wall of the stilling pool, difficulty in overhauling the large-scale stilling structure, and sedimentation in the energy dissipation section of the stilling pool, which leads to shortened service life. A large drop, the high-speed water flow scours and wears the structure or splashes out of the structure pool, which in turn affects a series of problems such as backfill around and the stability of surrounding structures
