Embodiment

[0023] Such as figure 1 As shown, a sponge city rainwater alternate utilization system includes a number of hollow ceramic pot half-rings 1 which form a circular ring. Plants are planted in the circular ring, and the The semi-rings of the earthenware pot are arranged in several, rather than a single circular ring, in order to avoid affecting the development of plant roots due to the existence of the circular ring during plant growth. The side of several earthenware pot half-rings 1 in contact with the water-permeable and water-retaining layer 2 is a water-permeable layer 5. The water-permeable and water-retaining layer 2 is made of sand, that is, the inner ring of the earthenware half-ring body 1 is water-permeable, and the outer ring is impermeable. The ring body 1 is hollow, so that the clay pot half ring body 1 can store and seep water. A plurality of said clay pot semi-ring bodies 1 form a circular ring body, in which a water-permeable and water-retaining layer 2 and a wate...

Abstract

The invention discloses an alternate rainwater utilization system for a sponge city. The system comprises multiple hollow ceramic jar semi-rings which form a round ring, a water seepage and retentionlayer and a water use layer are sequentially arranged in the round ring, the water use layer is arranged in the inner center of the round ring, and a seepage-proof water retention layer is arranged onthe periphery of the round ring; and one side, making contact with the water seepage and retention layer, of the multiple ceramic jar semi-rings is a water seepage layer. The multiple hollow ceramicjar semi-rings are arranged, one side, making contact with the water seepage and retention layer, of the multiple ceramic jar semi-rings is the water seepage layer, so that alternate utilization of rainwater in the sponge city is realized, automatic moisture preservation of soil is facilitated, the irrigation frequency is effectively reduced, energy saving and emission reduction effects are realized, and self-maintenance of urban green land is facilitated.

Description

Technical field [0001] The invention relates to the field of urban and rural planning sponge cities, in particular to a sponge city rainwater alternate utilization system. Background technique [0002] Sponge city means that the city can be like a sponge and has good "flexibility" in adapting to environmental changes and responding to natural disasters. It absorbs, stores, seeps, and purifies water when it rains, and releases the stored water when needed. use. The construction of sponge cities should follow the principle of ecological priority, combine natural methods with artificial measures, and maximize the accumulation, infiltration and purification of rainwater in urban areas under the premise of ensuring the safety of urban drainage and flood prevention, and promote the use of rainwater resources And ecological environment protection. [0003] When planting slope green plants under the background of sponge cities, especially in relatively arid areas, there are technical pro...
