An apparatus for protecting a tubular well and guiding the discharge of subterranean water is provided to facilitate the installation of a discharge guide pipe to an extension pipe by forming a vertical groove line on the inside wall. An apparatus for protecting a tubular well and guiding the discharge of subterranean water comprises an extension pipe(210) connecting with the tubular well, closing the upper part of the tubular well by closing one end, and having a first projection(213) on the inside wall and a fitting sill(215) opposite of the first projection; a discharge guide pipe(260) formed with a second projection(261) and a fitting projection(263) mounted on the surface corresponding to the first projection and the fitting sill, mounted in the extension pipe by combining the first projection and fitting sill with the second projection and the fitting projection, and installed to connect with an underwater motor pump so as to discharge subterranean water to the side surface of the extension pipe provided with the fitting sill; and a vertical groove line(280) vertically recessed with a size in which the fitting projection fits from the fitting sill on the inside wall of the extension pipe to a seal end in order to guide the installation of the discharge guide pipe. |
