Abstract:
PURPOSE: To construct the pit of an underground water storage tank readily at a low cost even in the soft ground containing underground water by closing the lower opening of a tubular body provided as a kettle part, and finally providing the pit.
CONSTITUTION: When the ground G, where an underground water storage tank 1 is provided, is dug, a kettle part, which is provided at the excavation bottom, is formed of a tubular body 4, which is opened at the upper and lower sides. When the excavation reaches the required depth, a bottom plate 8 of the water storage tank 1 is fixed to the tubular body 4 so as to form a unitary body. Then, the level of the ground water is lowered by the draining of the water from the tubular body 4. Thereafter, the lower opening of the tubular body 4 is closed with a closing plate 9.
