Construction process｜Water Storage Tank for firefighting purpose

Construction process

	１．Installation preparations ● Construct flat foundation with concrete.(Foundation may be unnecessary depending on soil quality and groundwater level) ● Lay rubber sheet to prevent damage to tank.	２．Delivery ● Deliver unitary tank by 10-ton truck or low-bed trailer.

３．Installation ● Attach designated wire and hooks to lifting lugs on tank and suspend it. ● Crane capacity must be at least 20 tons.(Varies depending on work radius)	４．Back filling ● Use earth and sand suited to site or soil generated from excavation or otherwise and exercise caution with back filling. ● Add water while sufficiently compacting backfill. ● Do not drive heavy machinery directly over water tank when back filling.

	1. Excavation at installation location and delivery ● Excavate burial site with excavator. ● Perform base leveling on installation surface and make it flat. ● Deliver divided tank with small truck.	2. Suspension ● As with solid type, suspend tank from hangers. ● Crane capacity must be at least 7.5 tons.

3. Assembly ● Weld parts together and make solid piece with FRP on inside and outside.	4. Base/top plate installation ● After getting down to position, attach base/top plates.
