Water-stacked landscape discharge chute

Abstract

The invention discloses a stacked water landscape discharge chute which comprises a stacked water discharge chute body and a water conveying system. The water stacking discharge chute comprises a bottom plate, a side wall, a drop sill and a water collecting sill; the side walls are located at the bottom and on the two sides of the stacked water discharge chute, and the drop sill is located on the upper portion of the bottom plate. The drop sill comprises an L-shaped plate, an anchor bolt and a rubber gasket, the L-shaped plate is fixed to the surface of the bottom plate through the anchor bolt, the rubber gasket is clamped between the L-shaped plate and the bottom plate, and water leakage is reduced. The water collecting ridge is located at the head end of the water stacking discharge chute and stores water stably on the initial water surface. The water delivery system comprises a water delivery pipe, a water intake, a vacuum pipe, a control valve and a submersible pump, and the water intake, the vacuum pipe, the control valve and the water delivery pipe form a siphon for self-flowing water diversion when the normal water level of the reservoir is higher than the water collecting ridge; the submersible pump is located at the front end of the water conveying pipe and used for pumping water to the sump when the reservoir normal water level is lower than the sump. The method has the advantages that the surface landscape of the discharge chute is improved, the landscape effect under the dam is improved, channels for discharging ecological flow are enriched, flood discharge is basically not affected, and construction is convenient.

Description

technical field [0001] The invention relates to a chute structure in a water conservancy and hydropower project, in particular to a chute structure with the effect of overlapping water landscape by upgrading and transforming a chute on a steep slope of a conventional spillway. Background technique [0002] The spillway chute is the main building in the reservoir hub, and it is the channel for the flood discharge of the reservoir. It is generally in an anhydrous drought state during most of the non-flood seasons or dry seasons. [0003] At present, more and more reservoir projects are being developed in combination with ecological landscape tourism. Conventional chutes are in a state of cut-off for a long time due to the low frequency of flood discharge through spillways. When the vegetation on both sides of the bank slope spillway is well covered, the large-area exposed concrete structure on the bottom of the chute has a greater impact on the landscape. As the requirements f...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings of the existing spillway chute, such as the low frequency of flood discharge and the poor ecological landscape effect of exposed concrete, and proposes a discharge that meets the requirements of ecological flow discharge, has the effect of cascading waterfall landscape, can discharge all year round, and is easy to construct. groove structure
