Navigation safety maintenance method for junction of canal main flow and branch flow
The navigation safety maintenance method is characterized in that energy dissipation treatment is conducted on river water of a canal branch before the river water flows into a main stream, the river water is guided to change the direction when the river water flows out of the branch, and the river water deflects towards the downstream direction and flows into the canal main stream. According to the method, the transverse flow velocity of the channel in the cross-basin canal main and tributary intersection area can be reduced, the channel water flow direction is adjusted to achieve the effect of improving the poor flow state of the intersection area, and the navigation safety of the artificial canal main and tributary river channel intersection is greatly improved.
本发明公开了一种运河干支流交汇处通航安全维护方法，其特征在于，对运河支流的河水在流入干流之前进行消能处理并引导其在流出支流时改变方向，使其往靠向下游的方向偏转出水流入到运河干流。本发明能够起到减小跨流域运河干支流交汇区航道横向流速、调顺航道水流方向，以达到改善交汇区不良流态的效果，极大地提高了人工运河干支流河道交汇处的通航安全性。
