An intelligent urban rainwater regulation and storage system and its construction method

Abstract

The invention discloses an intelligent urban rainwater storage regulation system and a construction method thereof. The system comprises a rainwater storage regulation tank, a water through device, a filter device and a water distribution tank. A first water level sensor and a second water level sensor are arranged on the inner side of a park pool, and the water through device is positioned between the first water level sensor and the second water level sensor and close to the second water level sensor. A silt clearing tank is arranged at the top of the park pool, the filter device is connected with a residence region and a road surface through a first water inlet pipe and a second water inlet pipe respectively, and the rainwater storage regulation tank is connected with the residence region and the water distribution tank through a first water drain pipe and a second water drain pipe respectively. The method includes steps of survey setting-out, rainwater storage regulation tank construction, filter device construction, water distribution tank construction, road surface construction, pipeline connection arrangement and rainwater storage regulation system commissioning. The construction method is simple in step, rainwater quick drainage and storage are facilitated, flood or waterlogging is prevented, and stored rainwater can be used for irrigation and domestic water.

Description

technical field [0001] The invention relates to an intelligent urban rainwater regulation and storage system and a construction method thereof. Background technique [0002] Water is an irreplaceable resource for human survival and development, an important material basis for sustainable social and economic development, and an indispensable controlling factor for the ecological environment. However, with the acceleration of urbanization and industrialization, the concentration of population and economic activities has changed the drainage performance and landform of the basin, changed the characteristics of rainwater runoff, and increased the impermeable area of ​​the city, such as streets, roofs, and parking lots. etc., so that a considerable part of the watershed is covered by impervious surfaces, so that rainwater cannot directly infiltrate into the ground, the water storage in depressions has been greatly reduced, and the flood disasters caused by urban storm runoff have...

AI Technical Summary

Problems solved by technology

However, with the acceleration of urbanization and industrialization, the concentration of population and economic activities has changed the drainage performance and landform of the basin, changed the characteristics of rainwater runoff, and increased the impermeable area of ​​the city, such as streets, roofs, and parking lots. A considerable part of the watershed is covered by impermeable surfaces, which prevents rainwater from directly infiltrating into the ground, greatly reducing water storage in depressions, and causing floods caused by urban storm runoff to become more serious. These changes in land use greatly shorten the time from rainfall to confluence , increasing the speed and runoff of the confluence, making the flood discharge capacity of the original urban pipelines overwhelmed, and the frequency of waterlogging or water netting also greatly increased

[0003] Although the rainwater regulation and storage system in the prior art can quickly discharge the water collected on the roof and road surface, the rainwater after discharge cannot be used, resulting in a waste of water resources
