Permeable ecological spur dike
The invention discloses a permeable ecological spur dike. A plurality of permeable holes are formed in a dike body of the spur dike in a penetrating mode, the permeable holes are horizontally formed, and the axes of the permeable holes deflect towards the direction of a river deep groove. The angle of the axes of the permeable holes deflecting towards the direction of the river deep groove is 10-12 degrees. According to the permeable ecological spur dike, the permeable holes are formed in the dike body, the local scouring strength of the dike body is reduced, and the stability of the structure is facilitated; the permeable holes penetrate through the dike body and are arranged in the mode of deflecting towards the direction of the river deep groove, a turbulent structure near the dike body can be effectively slowed down, and flow slowing and siltation promotion are facilitated; and the permeable holes can provide a certain habitat for aquatic animals such as fishes and shrimps, and the local micro-habitat of a river is improved. Compared with a solid spur dike, the permeable spur dike has a certain permeable rate, the scouring strength of a dike head is smaller than that of the solid spur dike, and the safety of the structure is high. In addition, the permeable holes can provide a certain habitat environment for the animals, and the improvement of a river micro-ecosystem is facilitated.
本发明公开了一种透水生态丁坝，该丁坝的坝体上设置有若干贯穿的透水，所述透水孔水平设置、轴线向河流深槽方向偏斜。所述透水孔的轴线向河流深槽方向偏斜的角度为10‑12°。本发明通过在坝体上设置透水孔，减轻了坝体局部冲刷强度，有利于结构自身稳定；透水孔贯穿坝体、向河流深槽方向偏斜设置，可有效减缓坝体附近的紊流结构，有利于缓流促淤；透水孔可为鱼虾等水生动物提供一定的栖息地，改善河流局部微生境。相对于实体丁坝，透水丁坝由于具有一定的透水率，坝头冲刷强度小于实体丁坝，结构本身的安全性高。此外透水孔洞可为动物提供一定的栖息环境，有利于河流微生态系统的改善。
