PURPOSE:To prevent deformation and breakage of a wall part due to an earth pressure, by a method wherein the upper opening part of a lower container body is connected to the lower opening part of an upper container to form a large inner peripheral part, and a cubic skelton shelf form body is fitted in a large inner peripheral part. CONSTITUTION:An upper opening part 2 of a lower container 1 having an inner peripheral part, the upper part of which is larger than a lower part thereof, is connected to a lower opening part 4 of an upper container 3 having an inner peripheral part, the lower part of which is larger than an upper part thereof, by means of flanges 10 to form a semiunderground containing chamber A. Cubic skelton shelf form bodies 9, coupled together by an upper shelf form 6, a lower shelf form 7, and a vertical form 8 and having configuration about equal to the size of the large inner peripheral part 5, is fitted in the large inner peripheral part 5. This permits prevention of deformation and breakage of a containing chamber due to an earth pressure and concrete-placing pressure, and enables prevention of entrance of underground water. |
