Problems solved by technology

[0004] The inventors have found that the storage and cross-seasonal utilization of water resources are currently mostly carried out by building dams for surface water storage, which occupies a large surface area, high construction costs, and serious evaporation losses of surface water bodies; because it is an open water storage, Susceptible to the influence of various pollution sources, the water quality of the water storage area is affected, and additional special purification equipment is required when taking it, which further increases the construction cost and the difficulty of utilization, and it is difficult to meet the existing requirements for water resource storage and trans-spanning. Demand for seasonal use

Abstract

The invention provides a method and system for storing water resources through an underground alluvial-proluvial fan, and relates to the field of water resource utilization. The method comprises the steps: determining the range and the form of an alluvial-proluvial fan area by determining an engineering site selection area and carrying out detection; obtaining water storage space reserves according to hydrogeological parameters; observing and analyzing the relation between the alluvial-proluvial fan area and surrounding hydraulic power, and determining a re-injection water rate; and accordingto the hydrogeological parameters, determining a water pumping rate during a test water pumping test. The alluvial-proluvial fan serves as an underground water storage space, the underground water regulation and storage effect is fully achieved, urban flood season rainwater or surplus recycled water is stored and purified to meet the standard and then recharged into a water storage area of the alluvial-proluvial fan, the part of water source is pumped as urban water in dry seasons, and the problem of urban seasonal water shortage is solved.

Description

technical field [0001] The present disclosure relates to the field of water resources utilization, in particular to a method and system for storing water resources by using underground alluvial fans. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] The alluvial fan is a fan-shaped accumulation body that spreads out from the mountain mouth when the slope of the mountain river drops suddenly, the water flow suddenly disperses, and a large amount of material accumulates, which is called an alluvial fan. Before the river exits the mountain mouth, there is generally a certain thickness of Quaternary sand pebble gravel covering layer, which has strong water permeability and large porosity, and the surface water is quickly converted into underground water. The alluvial-diluvial fan circle zone is composed of clay layer and fine sand layer, whic...
