Branched channel type approach channel arrangement method giving consideration to ecological and navigation benefits
The invention discloses a branch channel type approach channel arrangement method giving consideration to ecological and navigation benefits. A connecting section diversion embankment is arranged between an upper lock head of a ship lock and the tail of a river center; the connecting section diversion dike comprises a solid diversion dike end section, an overflow dam section and a bottom permeable dike section; wherein the bottom permeable part of the bottom permeable embankment section is an underflow and bottom aquatic organism channel, and the overflow dam section is a surface flow and floating object channel. According to the technology, a dredging and blocking combined arrangement method is adopted, a ship lock upstream approach channel diversion embankment is arranged at a branch branch outlet section to be of a structural style that the bottom is open and is combined with an overflow dam section, the open part of the bottom of the diversion embankment is mainly an underflow and aquatic organism channel, and the overflow dam section is mainly a surface flow and floating object channel; the water flow condition in the approach channel where the branched river reach is located can meet the standard requirement limit value, the branched river reach cannot be changed into a long dead water river reach, the flowability and the self-purification capacity of the river reach are kept, and the ecological balance of the river reach is maintained.
本发明公开了一种兼顾生态与通航效益的汊道型引航道布置方法，在所述船闸的上闸首与所述江心洲的洲尾之间设置有连接段导流堤；所述连接段导流堤包括实体导流堤端段、溢流坝段、以及底部透空堤段；其中所述底部透空堤段的底部透空部位为底流及底部水生生物通道，所述溢流坝段为表流及漂浮物通道。本发明技术采用疏堵相结合布置方法，在支汊出口段将船闸上游引航道导流堤布置为底部透空与溢流坝段相结合的结构型式，导流堤底部透空部位主要为底流及水生生物通道，溢流坝段主要为表流及漂浮物通道，使支汊河段所处引航道内水流条件即能满足规范要求限值，又不至于将支汊变成较长的死水河段，保持河到的流动性及自净能力，维持其生态平衡。
