Water collecting system of sponge park

Abstract

The invention discloses a water collecting system of a sponge park. The water collecting system sequentially comprises an organic covering material layer, an organic soil layer, a water permeating layer and a drainage layer from top to bottom. The drainage layer comprises a plurality of water pipes, the water pipes are positioned below the water permeating layer, drainage holes are formed in the upper portions of the water pipes, the water pipes are connected with one another by connecting pipes and are gathered and communicated with a header drainage pipe, and an output end of the header drainage pipe is communicated with a water storage device. The water collecting system of the sponge park has the advantages that rainwater can be stored, permeated and purified by the water collecting system to the greatest extent, and accordingly rainwater resource utilization and ecological environmental protection can be promoted; water can be effectively stored by the water collecting system, thewater collecting system further can cover bare soil, flying dust can be suppressed by the water collecting system, accordingly, the air quality can be improved, and activity spaces can be enlarged for people; soil structures can be improved, the fertility of soil can be enhanced, heat preservation and moisture preservation effects can be realized for the soil, the watering frequencies for plantedvegetation can be obviously reduced, and the water collecting system has important significance in increasing the utilization rate of organic waste, saving energy, protecting environment and carryingout ecological management.

Description

technical field [0001] The invention relates to the technical field of sponge park construction, in particular to a water collection system for a sponge park. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water. use. [0003] The so-called sponge park is to use the sponge city concept to transform the park, such as an ecological rain garden disclosed in CN107447839A. However, there are still many deficiencies in the construction process of the sponge park at present. For example, collecting rainwater by building drainage ditches or low-lying places, this method requires the soil to be saturated before overflowing into the ditch, and the collection amount is very limited. Another example is that in order to collect a large amount of rainwater or surface water, water-permeable m...

Problems solved by technology

However, there are still many deficiencies in the construction process of the sponge park at present. For example, collecting rainwater by building drainage ditches or low-lying places, this method requires the soil to be saturated before overflowing into the ditch, and the amount of collection is very limited.

Another example is that in order to collect a large amount of rainwater or surface water, the surface is made of permeable materials. Although the water permeability and collection capacity are improved, the area for greening and flower planting is reduced, and the ecological environment is destroyed.
