Pervious concrete pipeline system for reducing rainwater pollutant content

Abstract

The invention discloses a pervious concrete pipeline system for reducing rainwater pollutant content. The pervious concrete pipeline system comprises a concrete pipe, wherein a water filtering layer is wrapped outside the concrete pipe; the concrete pipe comprises a plurality of pervious walls and impervious walls, the pervious walls are mainly made of pervious concrete added with adsorbates, and the impervious walls are mainly made of impervious concrete. According to the invention, when the drainage volume is small, all the rainwater can be completely drained through impervious parts of the concrete pipe, and then concentrated; when the drainage volume is large, a part of rainwater can be completely drained through the impervious parts, and the other part of rainwater can be drained to surrounding media through the pervious parts to improve the drainage capacity of the pipeline; furthermore, the adsorbates can adsorb heavy metals in osmotic water to lower the pollution of the heavy metals to the environment; the water filtering layer can adsorb dissolved organic matters in osmotic water to reduce the influence of the organic matters on the environment.

Description

technical field [0001] The invention relates to a permeable concrete pipeline system for reducing the content of rainwater pollutants, and belongs to the technical fields of environment, construction and water conservancy. Background technique [0002] The urban rainwater pipe network is an important part of urban infrastructure construction. The urban rainwater pipe network needs to meet a certain amount of drainage to meet the requirements of urban drainage. However, due to the rapid development of urbanization and the impact of global climate change, the drainage capacity of urban rainwater pipe network often cannot meet the actual needs, especially in flood season or rainy season, urban waterlogging is often closely related to the short-term drainage capacity of rainwater pipe network. On the other hand, as rainwater enters concrete pipes through concrete pavement, etc., and is discharged into rivers, the ability of cities to store rainwater is getting weaker and weaker....

AI Technical Summary

Problems solved by technology

At present, the rainwater pipelines in the project are still mainly made of concrete pipes, which cannot meet the changing requirements of the drainage volume in different seasons, and cannot replenish the urban water environment in time. When the drainage capacity of the pipeline network is insufficient and the urban rainwater cannot be discharged in time, it will not only cause waterlogging and other disasters, it will also carry industrial and domestic pollutants to pollute the urban environment
