Saline-alkali region water resource regulation and storage utilizing system containing storage and permeation pipes

Abstract

The invention discloses a saline-alkali region water resource regulation and storage utilizing system containing storage and permeation pipes. The saline-alkali region water resource regulation and storage utilizing system comprises a soil body and water storage wells; the soil body comprises a planting soil layer, a permeable membrane layer, a water storage layer, waterproof layers and a saline-alkali soil layer which are sequentially arranged from top to bottom; a trench protruding into the saline-alkali soil layer is formed in the lower surface of the water storage layer and internally provided with a concealed conduit; the water storage wells are formed in the soil body at intervals; cobble ditches are formed in the upper surfaces of junctions of the planting soil layer and structuressuch as surrounding roads or squares, and fully filled with cobbles; and a water collecting opening is formed in the surface of the planting soil layer, the water storage pipe is arranged below the water collecting opening of the planting soil layer, the lower part of the water collecting opening communicates with the water storage pipe through a pipeline, and the side of the water storage pipe isprovided with the multiple permeation pipes. According to the saline-alkali region water resource regulation and storage utilizing system, rainwater collected into the planting soil layer after precipitation can be very effectively collected, and salt return of the saline-alkali soil layer to the planting soil layer is avoided; and the greening elevation of saline-alkali land can further be lowered, and the earth volume is decreased.

Description

technical field [0001] The invention belongs to the field of water resources treatment in saline-alkali areas, and in particular relates to a system for regulating, storing and utilizing water resources in saline-alkali areas with seepage pipes. 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 dif...

Problems solved by technology

However, the disadvantage of the existing method of "flooding with stone chips" and "salt drainage through hidden pipes" to control saline-alkali land is that after the rainwater infiltrates into the soil, it enters the saline-alkali layer through the stone chip layer, or is directly discharged into the municipal water. Drainage pipe network, rainwater cannot be effectively used, and at the same time, a large amount of nutrients such as nitrogen, phosphorus, and potassium are also discharged into the municipal rainwater system during the fertilization process, which also causes eutrophication of downstream water bodies; surface runoff that does not have time to infiltrate during rainfall Rainwater flows into low-potential areas such as surrounding roads, which increases road drainage pressure and waterlogging risk. At the same time, the green land soil washes the road surface with the runoff, causing runoff pollution such as mud left on the road after rain; the amount of land for greening is large and uneconomical
