Abstract

PROBLEM TO BE SOLVED: To preserve a large amount of outer tanks in a narrow place and to improve the efficiency of piling work for preservation by a method in which in the outer tanks for a sewage septic tank having a nearly square opening surface, one or more piling ribs are formed on opposite side walls of one pair out of two pairs of side walls in which the outer tanks are opposing on the inside. SOLUTION: A capsule type sewage septic tank is formed by joining the opening part flange surface of an upper tank 10 and the opening part flange surface of a lower tank 12. The upper tank 10, the lower tank 12, i.e., outer tanks 10 and 12 are preserved by piling stages. Piling ribs 11 and 13 are formed integrally on the inside walls of the outer tanks 10 and 12. The ribs 11 and 13, when the outer tanks 10 and 12 were piled, are formed from bottom walls 10b and 12b to a height so that the side surfaces of both are not contacted and set up to have a wall thickness and dimensions to be able to bear a mounting load. The ribs 11 and 13 are also ribs for preventing the deformation of the outer tanks 10 and 12. In this way, the outer tanks can be piled easily, and a large amount of the outer tanks 10 and 12 can be preserved in a narrow place.
