A structure and energy dissipation method for urban ponding monitoring oscillation elimination based on bottom flow energy dissipation

Abstract

The invention discloses an urban water monitoring oscillation elimination structure and energy dissipation method based on bottom flow energy dissipation, comprising a stilling pool arranged in a monitoring well; one end of the stilling pool is connected to a water inlet through a slope, and the other end of the stilling pool is The slope is 90°; monitoring equipment is installed in the monitoring well near the 90° slope side of the stilling pool. In the present invention, the structure of the stilling pool is set in the water accumulation monitoring well based on the principle of bottom flow energy dissipation, so that the water flow enters the monitoring well to generate a hydraulic jump, and the internal friction of the water flow, aeration and impact consume energy, and the fluctuation and impact of the accumulation water Weakening, in order to reduce the impact on the water monitoring equipment, can effectively reduce the impact and fluctuation of water on the monitoring equipment, so that the urban road surface water monitoring is more stable and accurate.

Description

technical field [0001] The invention belongs to the technical field of vibration elimination for water depth monitoring in urban floods, and in particular relates to an urban water monitoring oscillation elimination structure and an energy dissipation method based on bottom flow energy dissipation. Background technique [0002] With the increasing impact of climate change and urbanization, urban flood disasters have become more frequent, causing serious impacts and even losses on the normal operation of cities, economic and social development, and the normal lives of residents. One of the means to effectively deal with urban floods is to use monitoring methods to perceive the depth of accumulated water, and apply the accumulated water monitoring data to urban management, such as road traffic early warning, drainage and rescue, simulation forecasting, etc. In the monitoring of accumulated water, pressure-based Sensor-type and float-type water level gauges are installed at poi...
