US 2020/0024834 A1 · NON-POWERED SEAWATER PUMPING SYSTEM FOR REDUCING SEAWATER INTRUSION, AND APPARATUS AND METHOD FOR OPTIMAL DESIGN OF WELL IN THE SAME SYSTEM

Abstract

Disclosed is a non-powered seawater pumping apparatus for reducing seawater intrusion in a land in which an aquifer with a seawater-fresh water boundary surface is formed, the apparatus including a pumping pipe having opposite open end portions, a first end portion of the opposite open end portions being positioned below a sea level and a second end portion being positioned below a seawater-fresh water boundary surface in the land, and a well disposed to surround a lateral surface of a land-buried portion of the pumping pipe, which is buried in the land, so as to space away the land-buried portion of the pipe from the land, wherein seawater is filled in the pumping pipe, and the well includes a screen having a plurality of through holes formed along a circumference of the well at a lower end portion of the well.

Dependent claims

A non-powered seawater pumping apparatus for reducing seawater intrusion in a land in which an aquifer with a seawater-fresh water boundary surface is formed, the apparatus comprising:

a pumping pipe having two open end portions, a first end portion of the open end portions being positioned below a sea level and a second end portion being positioned below the seawater-fresh water boundary surface in the land;
and
a well disposed to surround a lateral surface of a land-buried portion of the pumping pipe, which is buried in the land, so as to space away the land-buried portion of the pipe from the land,
wherein:
the pumping pipe is filled with seawater;
and
the well comprises a screen having a plurality of through holes formed along a circumference of the well at a lower end portion of the well.

4 more elements

A hydraulic model device for simulation of a boundary surface of first fluid and second fluid with smaller specific gravity than the first fluid, the device comprising:

a water tank comprising a sand reservoir configured to at least partially accommodate sand and a first fluid reservoir and a second fluid reservoir, which are disposed at opposite sides of the sand reservoir and configured to store the first fluid and the second fluid, respectively;
a first screen interposed between the sand reservoir and the first fluid reservoir and having a plurality of through holes formed therein;
a second screen interposed between the sand reservoir and the second fluid reservoir and having a plurality of through holes formed therein;
a discharged water reservoir configured to store the first fluid discharged from the water tank;
a first water level adjustment device configured to adjust a water level of the first fluid reservoir;
and
a second water level adjustment device configured to adjust a water level of the discharged water reservoir at the same level as the water level of the first fluid reservoir.
