Measuring weir with super discharge capacity and arrangement method
The invention discloses a measuring weir with super discharge capacity and an arrangement method, the measuring weir is composed of a top rectangular section and a bottom Parshall groove, and the bottom Parshall groove can measure the flow during small-flow water passing; when large-flow flood is discharged, the flood is discharged through the top rectangular section and the bottom Parshall groove together; an upstream flood discharge open channel is connected through the inlet transition section, and a downstream flood discharge open channel is connected through the outlet transition section. A traditional water measuring facility is improved to become the water measuring weir, and the problem that a traditional water measuring weir cannot serve as a flood discharge open channel at the same time is solved. The small flow of water passing during irrigation can be measured, large-flow flood can also pass through, and damage to the measuring weir is avoided. Irrigation water can be provided according to the water demand condition of crops, the water amount can be measured, and the drainage efficiency can be improved through large flow during flood discharge. The method is reasonable in design, high in practicability and convenient to popularize and apply.
本发明公开了一种具有超泄能力的量水堰及布置方法，该量水堰由顶部矩形段、底部巴歇尔槽组成，底部巴歇尔槽可量测小流量过水时的流量；下泄大流量洪水时，通过顶部矩形段和底部巴歇尔槽共同排泄洪水；通过进口渐变段连接上游泄洪明渠，由出口渐变段连接下游泄洪明渠。对传统的量水设施的改进以成为本发明的量水堰，解决了传统的量水堰不可兼做泄洪明渠的难题。既可以量测灌溉时过水的小流量，又可以通过大流量洪水，而不造成量水堰的损害。本发明可以根据作物需水情况提供灌溉用水并量测水量，也能通过泄洪时的大流量进而提高排水效率。本方法设计合理、实用性强、便于推广和应用。
