Abstract

The invention discloses a simple saline-alkali region water resource collection and utilization system. The simple saline-alkali region water resource collection and utilization system comprises a soil body and an air vent hole; the soil body comprises a planting soil layer, a water-permeable membrane layer, an aquifer layer, a waterproof layer and a saline-alkali soil layer which are arranged from top to bottom in sequence; the planting soil layer and the aquifer layer are separated by the water-permeable membrane layer; the aquifer layer and the saline-alkali soil layer are separated by thewaterproof layer; the junction of the outer side of the soil body and surrounding buildings or structures is reversely wrapped with a lateral waterproof layer; and the air vent hole extends downward from the planting soil layer of the soil body to the water-permeable membrane layer. The simple saline-alkali region water resource collection and utilization system can effectively collect rainwater which infiltrates into the planting soil layer after rainfall, and does not cause salt in the saline-alkali soil layer to be returned to the planting soil layer; in addition, the simple saline-alkali region water resource collection and utilization system can further reduce the greening elevation of saline-alkali land, reduce the amount of earthwork and reduce runoff pollution to roads and other surrounding facilities; and in a saline-alkali water shortage zone, each drop of water infiltrated into soil cannot be drained.

Description

technical field

[0001] The invention belongs to the field of collection and utilization of water resources in saline-alkali areas, and in particular relates to a simple system for collecting and utilizing water resources in saline-alkali areas. Background technique

[0002] my country's per capita water resource consumption is only 30% of the world level, and most areas are short of water or severely short of water. In recent years, with the further deepening of urbanization, the demand for water resources is increasing. How to develop efficiently Utilization of water resources has become a challenge that the whole society needs to face together.

[0003] In order to explore the path of sponge city construction under different natural environments and urban forms, the country has carried out two batches of 30 sponge city pilot projects. At present, the construction of sponge cities has been carried out in full swing across the country, and different rainwater is used for diff...
