Abstract

The invention provides a governing system for underground water subjected to seawater intrusion, and a construction method of the governing system. According to the conditions of geology, topography,an underground quaternary aquifer and the natural slope of the aquifer from the upstream part of an underground water area to a seawater intrusion water inlet section, a seawater-preventing dike is constructed at a seawater intrusion water inlet, and a plurality of automatic opening-closing valves are distributed on the seawater-preventing dike; and under the condition of the seawater normal waterlevel elevation or tidal wind wave water level elevation, the seawater-preventing dike can thoroughly block a seawater intrusion water inlet channel, thus seawater cannot invade the inner side of theseawater-preventing dike in an intrusion mode, and water on the inner side of the seawater-preventing dike utilizes natural hydraulic kinetic energy generated by upstream underground water of the underground water area through the downstream slope to break through valve plates of the automatic opening-closing valves to be discharged. According to the governing system, the self-cleaning function of a seawater intrusion area is achieved, thus the governing problem of the seawater intrusion area is solved, ecological self-restoration is achieved, the environment is protected, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of environmental protection water supply engineering and underground water conservancy engineering, and in particular relates to a control system and a construction method for groundwater backflow by seawater. Background technique [0002] In recent years, the melting of glaciers in the north and south poles of the earth has accelerated, and the water level of seawater has continued to rise. Groundwater in many countries has been polluted more and more by seawater intrusion, but no good solution has been found yet. This is a big issue related to drinking water for humans and animals, industrial and agricultural development, afforestation, and environmental climate improvement in many countries. It is particularly important and urgent to speed up the research on the control of groundwater intrusion by seawater. [0003] At present, there is not yet a complete set of treatment methods for the treatment of groundwater b...
