Water storage structure capable of improving moisture content in underground soil of urban street trees

Abstract

The invention relates to a water storage structure capable of improving moisture content in underground soil of urban street trees. The water storage structure comprises water seepage and storage pools and overflowing pipelines; each water penetration and storage pool comprises a pool body upper cover and a composite penetration layer; each pool body upper cover is a container of which the upper end is closed and the lower end is open; overflowing openings are formed on the inner walls of the pool body upper covers; the composite penetration layers are arranged at the openings at the lower ends of the pool body upper covers, and water penetration and storage cavities capable of accommodating rainwater are formed between the composite penetration layers and the pool body upper covers; the overflowing openings of the adjacent water penetration and storage pools are communicated with the overflowing pipelines. The water storage structure has the advantages that the water storage structure has both water penetration and storage functions; rainwater in urban rainwater wells can be collected by the water penetration and storage pools; the rainwater is stored in the water penetration and storage cavities, and slowly penetrates and supplements underground water through the composite penetration layers; penetrating rainwater can be adsorbed by the street trees, and the street tress do not need to be irrigated by municipal water resources. A volume of water for municipal greening and irrigation is reduced.

Description

technical field [0001] The invention relates to an urban drainage pipe network system, in particular to a water storage structure capable of improving the moisture content of underground soil of urban street trees. Background technique [0002] The emergence of the urban heat island effect has led to an increase in the probability of urban rainstorms and concentrated precipitation. At present, cities are basically traditional hardened drainage facilities, which only have the function of "drainage", that is, rainwater is quickly drained away through underground sewers. This can cause the following problems: [0003] 1. When a heavy rain comes, the underground pipe network is difficult to handle a large amount of flood immediately, which can easily cause urban waterlogging and cause losses to people's lives and properties. [0004] 2. When the rainstorm comes, the rainwater will flow away quickly and will not enter the underground soil layer. The soil layer cannot collect th...

Problems solved by technology

[0003] 1. When the rainstorm comes, the underground pipe network is difficult to handle a large amount of flood immediately, which can easily cause urban waterlogging and cause losses to people's lives and property.

[0004] 2. When the rainstorm comes, the rainwater will flow away quickly and will not enter the underground soil layer. The soil layer cannot collect the water well

This will result in a long-term water shortage state where "urban soil usually has no water supply, and the water that falls during heavy rains cannot be collected", resulting in dry soil.
