Pier tail structure of double-conveyance aqueduct
The invention provides a pier tail structure of a double-conveyance aqueduct. The pier tail structure comprises a narrow tail pier, a middle partition wall, an aqueduct left ditch, an aqueduct right ditch, an open channel gradual-changing section. The aqueduct left ditch and the aqueduct right ditch are disposed with the central line of the middle partition wall as the symmetry axis. The tail endof the middle partition wall is connected with the narrow tail pier. The narrow tail pier is disposed with the central line of the middle partition wall as the symmetry axis. The middle partition wall, the narrow tail pier and the open channel gradual-changing section are all disposed with the central line of the middle partition wall as the symmetry axis. The widths from the head end to the tailend of the narrow tail pier gradually decrease, so that separation of water flow boundary layers attached to the left and right side walls of the narrow tail pier becomes slow. Compared with a traditional dual-conveyance aqueduct pier tail structure, the pier tail structure can prevent water flow from fluctuating drastically during aqueduct water conveyance, improve stress characteristics of the aqueduct structure and improve the water conveyance capacity of the aqueduct, and has guidance significance in designing the dual-conveyance aqueduct during a water diversion project.
本发明提供一种双线输水渡槽的墩尾结构，包括窄尾墩、中隔墙、渡槽左槽、渡槽右槽、明渠渐变段，渡槽左槽和渡槽右槽以中隔墙的中心线为对称轴布置，中隔墙的末端连接窄尾墩，窄尾墩以中隔墙的中心线为对称轴布置，所述中隔墙、窄尾墩、明渠渐变段均以所述中隔墙的中心线为对称轴布置，所述窄尾墩首端到尾端的宽度逐渐减小，以使贴附于所述窄尾墩左右两侧壁的水流边界层分离变缓。本发明与传统的双线渡槽墩尾结构相比，能够避免渡槽输水时出现水流大幅波动，改善渡槽结构受力特性，提高渡槽输水能力，本发明对调水工程双线渡槽设计具有指导意义。
