Flood water storage recycling system for sponge city and construction method thereof

Abstract

The invention discloses a flood water storage recycling system for a sponge city and a construction method thereof; the flood water storage recycling system comprises a flood storage pond, a flood recycling pond, a shunt and a purifying device; the flood storage pond is connected with an urban ditch through an open ditch, a trash filtering device is arranged on the open ditch, the bottom end of the flood storage pond is connected with the flood recycling pond through a first draining pipe; a water suction pump is arranged on the first draining pipe; a settling pond is arranged between the flood recycling pond and the urban ditch; the shunt is arranged in the settling pond, and both sides of the shunt are respectively connected with the urban ditch and the flood recycling pond through a water inlet pipe and a water outlet pipe. The construction method includes steps of measurement and sampling, flood storage pond construction, flood recycling pond construction, settling pond construction, purifying device construction, and test running of the flood storage recycling system. The flood water storage recycling system can well prevent flood and effectively recycle flood, thus the system and method improve the utilization rate of water resource, reduce the flood influence on city and avoid urban inland inundation.

Description

technical field [0001] The invention relates to a flood storage and recycling system in a sponge city and a construction method thereof. Background technique [0002] Flood is a natural phenomenon caused by natural factors such as heavy rain, rapid melting of ice and snow, storm surge and other natural factors. But for most cities, due to the extremely destructive power of floods, it will not only cause urban waterlogging, but also seriously affect people's travel and personal safety. It will take a long time for the floods to recede, so the entire city will be paralyzed. [0003] In the prior art, there is no method that can effectively and quickly reduce the water level of urban rivers. Therefore, when a flood occurs, the impact range is very wide, which will pollute the water quality of urban rivers, affect the normal water delivery of the municipal pipe network, and easily cause water resources. of waste. SUMMARY OF THE INVENTION [0004] The purpose of the present i...

[0003] In the prior art, there is no method that can effectively and quickly reduce the water level of urban rivers. Therefore, when a flood occurs, the range of influence is very wide, which will pollute the water quality of urban rivers, affect the normal water delivery of the municipal pipe network, and easily cause water resource pollution. waste of
