Abstract

PURPOSE: To attain the captioned method wherein the capability to collect underground water is large, the enlargement of the working range of the ground layer to which the method is applied and the energy-saving for the worked wells are enabled, and the constitution is simpler than that in a vacuum deep-well method.
CONSTITUTION: A screen area 5 is formed in the lower part of a well casing 3 and the casing 3 is inserted in a hole. Meanwhile, an underwater pump 7 used as a deep well pump is set in the bottom part inside the well casing 3, and the water-lifting pipe 8 of the underwater pump 7 is led out on to the ground surface. Next, in the position above a screen area 5 an intercepting wall 10 is formed so as to enclose air- tightly the inside of the well casing 3. As a result, when the water lifting is started by driving the underwater pump 7, the level of the underground water inside the casing 3, especially in the part below the intercepting wall 10, lowers and produces the phenomenon of negative pressure, thereby the underground water in the surrounding ground being collected forcedly.
