RAINWATER STORAGE TANK FORMED BY BURYING MULTIPLE STORAGE TANKS UNDERGROUND

摘要

PROBLEM TO BE SOLVED: To provide rainwater storage tanks formed by burying multiple storage tanks underground, allowing use of a large amount of rainwater for home garages, parks, kitchen gardens or vinyl houses in preparation for water shortage in the global warming era.SOLUTION: Storage tanks 2 are formed by providing water-passing connections 3 at lower parts of four sides of box-type tanks 1 and vent holes 5 on upper faces, and the storage tanks 2 are connected to water collecting drains 6 by using water collecting drain connection members 7. Storage tank connection members 8 are used for connecting the multiple storage tanks 2, and the water-passing connections 3 not used for connection are blocked with cutoff plates 12. Each of the connection faces is blocked and fixed with bolts 11 sandwiching a block packing 10. Rainwater storage tanks needing no installation place, free in forms and having large capacities can be structured by burying underground rainwater storage tanks 13 formed by connecting the water collecting drains 6 to the multiple storage tanks 2.SELECTED DRAWING: Figure 1
