Problems solved by technology

[0004] In actual engineering, due to the large single-width flow rate and high flow velocity at the outlet of the diversion box culvert, direct access to the upper pool may cause large and uneven fluctuations in the water surface of the upper pool. Therefore, it is necessary to design a reasonable and beautiful hydraulic connection project for the water outlet. Provide the landscape effect of calm water surface for Shangtan

Embodiment 1

[0028] (1) Preliminary design of the outlet connection section of the Niulanjiang-Dianchi Lake water replenishment project. The outlet box culvert adopts a closed rectangle with variable cross-section. The flow velocity distribution of the water outlet is consistent, but due to the design of the steep sill, the flow velocity in the local area before the sill is low, and the body shape needs to be optimized.

[0029] (2) Change the steep slope to a gentle slope, and at the same time raise the bottom plate of the water outlet near the box culvert by 15cm, raise the half-distant ones by 10cm and 5cm, and maintain the original elevation of the two furthest ones.

[0030] (3) Considering the influence of the 70° turn of the water diversion box culvert on the outlet flow, the maximum difference between the flow rates of each outlet is 0.399m 3 / s, the flow distribution of each water outlet is relatively uniform, and the 70° turn of the diversion box culvert causes a certain head los...

Abstract

The present invention is an application of "Kowloon Exit" in the outlet connection section of hydraulic engineering and hydraulic engineering. The water outlet and outlet box culvert adopt a variable cross-section closed rectangle to ensure that the outflow of the nine outlets is basically the same. The application of the present invention makes the flow volume of each outlet consistent, and the water surface on the beach is calm, which not only makes full use of water energy, ensures the consistent flow state of each outlet, realizes a good outflow effect of the outlet connection section, but also ensures the landscape of the calm water surface It has good social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of hydraulic connection engineering of water outlets, in particular to the application of "Kowloon outlet" in the outlet connection section of hydraulic engineering and hydraulic engineering. Background technique [0002] Ecological hydraulics and landscape hydraulics are currently emerging hot topics in international research, and are an emerging interdisciplinary subject that interacts between hydrodynamics and ecological landscape theory. Judging from the current research status, the research objects of landscape hydraulics are generally large-scale water conservancy landscapes in complex real environments, and the calculation requirements of its hydraulic characteristics are different from traditional hydraulics such as flood discharge and overflow. On the one hand, there is a lack of corresponding regulations and specifications On the other hand, due to the large scope of landscape engineering, various ...
