<p>PURPOSE:To reduce the cost, and to minimize any hazard due to overflow of stored liquid by engaging a holding member installed on the outside of the spherical shell with the engaging area provided on the inner surface of the high liquid preventive dike, and by making the high liquid preventive dike to hold the spherical shell directly. CONSTITUTION:The spherical shell 3 is directly held on the high liquid preventive dike 7 with an engaging part 13 istalled on the inner surface of a high liquid preventive dike 7, and a holding member 20 installed on the outside of spherical shell 3, the holding member 20 engaged with the engaging area 13. Thus, since the liquid preventive dike 7 occupies a small area, the cost can be reduced, and even if stored liquid leaks and flows out, the liquid can be confined in the liquid preventive dike 7, to reduce the latated hazard.</p> |
