A remote adjustment device for the amount of air intake for a siphon water supply system that allows remote adjustment of the opening amount of the air intake port of the air intake member, a siphon water supply system equipped with this remote adjustment device, and a water supply construction method using the siphon water supply system.

Abstract

This invention provides a remote air intake volume adjustment device for a siphon water supply system that prevents the siphon tube (tube member) from becoming blocked by allowing external air to flow into the tube member according to the degree of negative pressure inside the tube member. [Solution] The remote air intake volume adjustment device 100 for the siphon water supply device is connected on one end to the air intake port 110 of an air intake member 90 provided on a part of the pipe member 10 that constitutes the siphon water supply device 200, and on the other end, the opening size of the valve-equipped opening with a handle is operated remotely from a safe location. By doing so, outside air is automatically drawn into the pipe member 10 in accordance with the amount of increase in negative pressure inside the pipe member 10 due to the siphon action, thereby mitigating the negative pressure inside the pipe member 10 so that it does not become so large as to block the pipe member 10, and preventing the pipe member 10 from becoming blocked.
