Fish passage with suitable habitat and construction method thereof
The invention discloses a fish passing channel with a suitable habitat and a construction method of the fish passing channel, and belongs to the field of river aquatic organism protection. The fish passing channel comprises a channel and a fish passing structure; a first deep water slow flow area, a dredged river section and a second deep water slow flow area are sequentially arranged on the bottom wall of the channel. The part above the dredging line of the dredged river section is excavated to form a dredged riverbed; the power generation tail water outlet is formed in the side wall of the channel at the position of the first deep water slow flow area; the fish passing structure is embedded in the dredged riverbed, the upstream end of the fish passing structure extends into the downstream face of the first deep water slow flow area, and the downstream end of the fish passing structure extends into the upstream face of the second deep water slow flow area; the fish passing structure is provided with a plurality of channels, and holes used for building fish rest and hole building structures used for reducing the water flow speed in the channels are arranged in the channels. The fish passing structure is embedded in the dredged riverbed, the dredged riverbed is repaired while the hydroelectric generation water head is increased, and resting, hiding and upstream channels are created for fishes.
本发明公开一种具有适宜生境的过鱼通道及其施工方法，属于河流水生生物保护领域。过鱼通道包括渠道和过鱼结构；在渠道的底壁上依次设置有第一深水缓流区、被疏浚河段、以及第二深水缓流区；被疏浚河段疏浚线以上部分开挖后形成被疏浚河床；发电尾水出口设置在第一深水缓流区位置处的渠道侧壁上；过鱼结构嵌在被疏浚河床内，过鱼结构的上游端伸入至第一深水缓流区下游面，下游端伸入至第二深水缓流区上游面；过鱼结构上具备多个通道，并在通道内设置有用于营造鱼类休憩孔隙、以及降低通道内水流速度的孔隙营造结构。本发明通过将过鱼结构嵌在被疏浚河床内，实现增加水力发电水头的同时，修复了被疏浚河床，为鱼类营造休憩、藏匿和上溯通道。
