<p>The tank (1) has similar bubble-shaped tank modules (3-5) with a sector shaped cross section concentric to a center. The modules are formed by two inner walls aligned at an obtuse angle to each other, a cylindrical mantle section (10), a lower base (11), an upper base (12) and a pin (13) with a man hole that is closed by a cover (14). The mantle section is reinforced by horizontal circumferential beadings (18) and vertical longitudinal beadings (19). The inner walls have vertical ribs which are provided to vertical beadings for assembling the modules and for reinforcing the inner walls.</p> |
