一种侧堰式溢洪道

Side-weir-type spillway

Abstract

The utility model relates to a side-weir-type spillway, and aims to provide a side-weir-type spillway which is simple in structure and convenient to construct in order to guarantee that a hole body section of a discharge chute has enough discharge capacity to enable the discharge capacity of the hole body section to be equal to or slightly higher than the discharge capacity of a side groove section. According to the technical scheme, the side-weir-type spillway is provided with a side weir and the side groove section is arranged behind the side weir. The side-weir-type spillway is characterized in that the side groove section is joined with the hole body section of the discharge chute through a gradually-changing contraction section, the side, close to the side weir, of the gradually-changing contraction section is an arc gradually-changing face and the other side of the gradually-changing contraction section is a torsion face. The side-weir-type spillway is applicable to flood discharge buildings in water conservancy and hydropower engineering.
本实用新型涉及一种侧堰式溢洪道。本实用新型的目的是提供一种结构简单、施工方便的侧堰式溢洪道,以保证泄槽洞身段具有足够的泄流能力,使其与侧槽段的泄流能力基本相当或略大。本实用新型的技术方案是:一种侧堰式溢洪道,具有侧堰,其后为侧槽段,其特征在于:侧槽段经渐变收缩段衔接泄槽洞身段,渐变收缩段靠侧堰侧为圆弧渐变面,另一侧为扭曲面。本实用新型适用于水利水电工程泄洪建筑物。
