摘要

The present invention relates to an upper protection pipe for an underground water pipe well for connecting an underground pump pipe (C) to a water intake pipe connected to a water intake destination at an upper portion of a pipe well casing (L) installed for taking underground water. The upper protection pipe comprises: an outcasing pipe (10) in which an upper opening, which has a flange portion at both ends thereof and is formed in a pipe shape, is exposed on the surface of the ground, a lower end thereof is connected to an upper end of the pipe well casing, and an upper end thereof is coupled to a lower portion of an upper case (60); and a water pipe (20) which has an L-shaped pipe shape and is integrally formed on one side of the inner circumference of the outcasing pipe (10) and in which a water pipe outlet portion (22) connected to the pipe for sending water to the water intake destination is formed at a lower end thereof, and a water pipe inlet portion (21) to which a meter outlet portion (71a) of a meter portion (70) is connected at an upper end thereof is provided. Therefore, the upper protection pipe is easy to manufacture, install, and maintain. And the cost is cheap.
