Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, in particular to a sluice and weir system suitable for narrow rivers. Background Art
[0002] Urban rivers are not only important flood discharge channels, but also need to meet the ecological requirements of water storage to create landscape water surfaces. Therefore, the integrated structure of sluice gates combined with overflow weirs is often adopted, and the "single-line" scheme is adopted, that is, the two are located in a straight line, and the sluice gates are concentrated on one side of the bank, which is generally asymmetrical. When storing water, the gates are always closed, and the excess water flows away from the overflow weir to form a stable water storage level. When discharging floods, the gates are always open, and water can flow away from the sluice gates and overflow weirs.
[0003] When the sluice gate has not yet reached the conditions for flood discharge, the upstream water must flow away from the overflow weir. Under the design conditions of small water depth and large flow, the overflow weir requires a longer flow length. However, urban rivers are generally narrow and lack space, making it difficult to meet the "one-line" layout requirements. Buildings on both sides of the river need to be demolished for expansion. The asymmetric overall layout causes the water flow to flow down to one side, causing serious local scouring, affecting the structural safety of the sluice gate and overflow weir and the safety of river flood discharge.

[0035] There are two overflow pathways for river water.
