Deep groove-shallow structure suitable for urban river channel hydrodynamic improvement
The invention discloses a deep groove-shallow structure suitable for urban river channel hydrodynamic improvement. The structure comprises a deep groove and a shallow, wherein the deep groove is provided in one side of a river channel, and the deep groove is sunk from an original riverbed of the river channel; and the shallow is arranged on the other side, opposite the deep groove, of the river channel, and comprises a gabion spur dike vertical to a river channel revetment, the two sides of the upstream part and the downstream part of the gabion spur dike are provided with arc-shaped wood pilewalls, one ends of the two arc-shaped wood pile walls are both fixedly connected to a jetty head of the gabion spur dike, the other ends of the two arc-shaped wood pile walls are fixedly connected tothe river channel revetment, a dam front region and a dam rear region are formed on the upstream and downstream sides of the gabion spur dike, the dam front region is filled with a shallow beach soilbody to form a dam front shallow, and the dam rear region is filled with a shallow beach soil body to form a dam rear shallow. The structure is stable in structure, simple in structure, remarkable inwater power improvement effect, capable of greatly reducing development damage to a riparian zone to a great extent, capable of effectively improving hydrodynamic force of the river channel at the same time, and achieving diversified water flow conditions and diversified biological habitats.
本发明公开了一种适用于城镇河道水动力改善的深槽‑浅滩结构，包括深槽和浅滩；深槽设置在河道的其中一侧，深槽自河道的原河床下凹；浅滩设置在河道的与深槽相对的另一侧，浅滩包括垂直于河道护岸布置的石笼丁坝，石笼丁坝的上、下游两侧均设置有弧形木桩墙，两个弧形木桩墙的一端均与石笼丁坝的坝头处固定连接、另一端均与河道护岸固定连接，在石笼丁坝的上、下游两侧形成坝前区域和坝后区域，坝前区域内填充浅滩土体形成坝前浅滩、坝后区域内填充浅滩土体形成坝后浅滩。本发明结构稳定，构造简单，水动力改善效果显著，可以在很大程度上减少对河岸带的开发破坏，同时有效改善河道水动力，实现水流条件多样化与生物栖息地多样化。
