Abstract
PURPOSE: To remove underground water partially to control subsidence of surrounding ground by using such a simple device that keeps compressed air pressure by the ground lying from the surface of land to the surface of underground water lowered by the compressed air supplied through many airpipes with exhaust orifices on their tip laid in the ground.
CONSTITUTION: A number of airpipes 1 are laid at a given interval in the ground planned to be cut open. In addition, sheet pile for stop water 4 is struck in along the outer periphery of the site of excavation to intercept outflow of compressed air to the outside of sheet pile range, if required for the conditions of ground. Compressed air is supplied for airpipe 1 which is connected with compressor 2 through airhous 3. By compressed air supplied the underground water is pushed upward, downward and to the side. The underground water pushed upward gushes out to the surface of land, but after a certain quantity of it gushing out, only compressed air is to run out. The underground water pushed downward makes bondary on its surface with the compressed air. Excavation is commenced when or before such a stationary state is attained.
