Layered orientation permeable partition dike
The invention relates to the field of water engineering and shipping engineering, and discloses a layered orientation permeable partition dike. The layered orientation permeable partition dike comprises a permeable partition dike body, a plurality of permeable holes communicating with an approach channel and a riverbed are formed in the horizontal direction of the permeable partition dike body side by side, a water diversion partition plate for uniformly dividing the permeable holes into a plurality of layers of permeable openings from top to bottom is arranged in each permeable hole, each permeable hole is located at the downstream of a riverbed opening, of an opening of the approach channel, each permeable opening is located below the riverbed opening, of the opening of the approach channel, projections of the permeable holes on a horizontal plane form an included angle alpha with axes of the approach channel, included angle alpha is 30 degrees to 60 degrees, projections of the permeable openings on a vertical face form a dip angle beta with a vertical line, and the dip angle beta is 45 degrees to 60 degrees. According to the layered orientation permeable partition dike, the influence of bad flow states such as cross flow, backflow and whirlpool of an entrance area of the approach channel is alleviated, the navigation condition of the entrance area is effectively improved, meanwhile, the surface flow state in the approach channel cannot be deteriorated, and meanwhile, other greater costs are not required to be paid.
本发明涉及水利工程和航运工程领域，公开了一种分层定向透水式隔流堤，包括透水式隔流堤主体，透水式隔流堤主体在水平方向上并排开有若干个连通引航道和河床的透水孔，每个透水孔内设有将透水孔由上至下平均分为若干层透水孔洞的导水隔板，每个透水孔洞位于引航道开口在位于河床开口的下游，每个透水孔洞位于引航道开口在位于河床开口的下方，且透水孔在水平面上的投影均与引航道轴线形成夹角α，为30°～60°，透水孔洞在立面上的投影与竖直线形成倾角β，为45°～60°。本发明分层定向透水式隔流堤，减轻引航道口门区横向流、回流及泡漩等不良流态影响，有效改善口门区通航条件的同时，不会恶化引航道内的表面流态，同时不需要付出较大的其他代价。
