Urban ponding monitoring oscillation eliminating structure based on underflow energy dissipation and energy dissipation method thereof

Abstract

The invention discloses an urban ponding monitoring oscillation eliminating structure based on underflow energy dissipation and an energy dissipation method thereof. The urban ponding monitoring oscillation eliminating structure comprises a stilling pool arranged in a monitoring well, one end of the stilling pool is communicated with the water inlet through a slope, and the other end of the stilling pool has a 90-degree slope; and monitoring equipment is arranged in the monitoring well close to the 90-degree slope side of the stilling pool. The stilling pool structure is arranged in the ponding monitoring well based on the underflow energy dissipation principle, water flow is promoted to generate hydraulic jump when entering the monitoring well, energy is consumed through internal friction, air entrainment and impact of the water flow, fluctuation and impact of ponding are weakened, the influence on ponding monitoring equipment is reduced, impact and fluctuation of accumulated water on monitoring equipment can be effectively weakened, so urban road surface accumulated water monitoring is more stable and accurate.

Description

Technical field [0001] The present invention belongs to the technical field of oscillation cancellation monitoring of the water depth of urban floods, and specifically, the present invention relates to an urban water monitoring oscillator elimination structure and its dual energy method based on ground-flunging. Background technique [0002] With the increasing impact of climate change and urbanization, urban flood disasters have become more frequent, giving urban normal operation and economic and social development, and residents have serious affected and even losses. Effectively correspond to one of the means of urban floods, using monitoring ways to perceive water depth, using water monitoring data in urban management, such as road pass warning, drainage rescue, simulation forecast, etc., in water monitoring, usually based on pressure Sensing and floating water level gauges are mounted in easy-to-pending point, and the water flow is passed through the monitoring pool. After th...
