Gallery split-flow port type of multi-section water delivery system of high-water-head ship lock
The invention relates to a gallery split-flow port type of a multi-section water delivery system of a high-water-head ship lock, which belongs to the field of navigation buildings, and is an improvement on the split-flow port type in the prior art. The middle of a first-stage branch gallery is connected with a second-stage split-flow port, the second-stage split-flow port is of a trisection type, the upper layer and the lower layer are equally divided, the equally-divided upper layer is connected with a bidirectional 180-degree horizontal symmetrical turn, and two second-stage branch galleries are divided on a plane; the equally-divided lower layer adopts a second-stage straight gallery, and a third-stage split-flow port is formed in the tail end of the equally-divided lower layer. A novel staged split-flow port configuration is provided, so that the problem of large resistance coefficient difference caused by different turning types of the upper-stage split-flow port of the branch gallery is effectively reduced; the uniformity of outflow of the branch galleries of the four sections of the lock chamber is effectively improved, then the water surface slope of the lock chamber and the mooring force of ships in the lock chamber are reduced, and the mooring safety of the ships of the high-water-head ship lock is guaranteed.
本发明涉及一种高水头船闸多区段输水系统的廊道分流口型式，属于通航建筑物领域。是对现有技术分流口型式的改进。包括：一级分支廊道在中部接二级分流口，所述的二级分流口为三分体型，上下层等分，其中等分后的上层接双向180°水平对称转弯，在平面上分为两个二级分支廊道；等分后的下层采用二级直进廊道，在末端设置三级分流口。本发明的优点在于：提出了一种新型式的分级分流口配置，有效地减小了分支廊道由于上一级分流口转弯型式不同造成的阻力系数差异大的问题；有效地提高了闸室四个区段的分支廊道出流的均匀性，进而减小闸室水面坡降和闸室内船舶系缆力，保障高水头船闸船舶的停泊安全。
