Horizontally-layered narrow-slit energy dissipater
The invention discloses a horizontally-layered narrow-slit energy dissipater. The horizontally-layered narrow-slit energy dissipater comprises a bottom plate, side walls symmetrical with the two sidesof the bottom plate, an equal-width section and a narrow-slit section, the equal-width section and the narrow-slit section are sequentially connected in the water flow direction, the positions, on the equal-width section, of the bottom plate are equal in width, and the positions, on the narrow-slit section, of the bottom plate is gradually shrunk from a narrow-slit starting end to a narrow-slit outlet end; a plurality of through grooves transversely penetrating through the side walls are transversely formed in the side walls of the two side walls of the narrow-slit section, so that a plurality of tooth piers are formed on the side walls, the through grooves and the tooth piers on the left side wall and the right side wall are symmetrically arranged, the left tooth pier and the right toothpier which are symmetrical are taken as one layer to form multiple layers of tooth piers, and horizontal layering is conducted while overflowing water is ejected. The problems that due to the fact that the outlet water depth of an existing narrow-slit energy dissipater is high, a side wall is too high, the dynamic water pressure of the side wall is too large, the stability of the side wall is threatened, a nappe is unstable, the horizontal length of the nappe is too large, and the project investment of a plunge pool is increased are solved.
本发明公开了一种水平分层的窄缝消能工，包括底板和底板两侧对称的边墙，沿水流方向为依次相接的等宽段和窄缝段，所述等宽段的底板各处等宽，所述窄缝段的底板自窄缝起始端到窄缝出口端逐渐收缩；窄缝段的两边墙侧壁横向设置有若干横向贯通侧壁的通槽，从而在侧壁上形成若干齿墩，左右两侧壁上的通槽和齿墩分别对称设置，以左右两个对称齿墩为一层，形成多层齿墩，实现在将过流水体挑射的同时进行水平分层。解决现有窄缝消能工因出口水深较高，导致边墙过高，侧壁动水压强过大威胁边墙稳定，以及水舌不稳定性，挑距过大增加水垫塘的工程投资等问题。
