Description

Underground structure for adjusting soil humidity of real grass playground according to rainfall condition

Technical Field

The utility model relates to a sponge city underground water storage drainage system technical field, in particular to adjust real grass playground soil moisture's underground structure according to the precipitation condition.

Background

The sponge city is a city which can adapt to the change of the city environment like a sponge, and is an innovative expression of the development of low-carbon cities in a new era.

The ground (mainly green land) drainage system in the sponge city only considers how to quickly drain accumulated water under heavy rain conditions and has no function of irrigating green land under drought conditions. And accumulated water is discharged as waste water, which is very waste. The water source used by the water-saving irrigation technology of the underground drip irrigation is all supplied with water from the outside, and the regulation function of self-storing or releasing redundant rainwater is not provided. Therefore, there is a need for an underground structure that adjusts the soil moisture of a real grass playground according to precipitation conditions.
