2. Description of the Related Art With respect to a structure used as a fire prevention water storage tank (hereinafter, referred to as a water tank), the Ministry of Home Affairs, Fire and Disaster Management Agency has indicated the standard of fire protection and waterproofing. As a material for the aquarium, it has the required strength against load and deformation to meet such standards,
Durable and watertight are required,
Conventionally, reinforced concrete, prestressed concrete, steel or a composite thereof has been used.

One example of such a conventional water tank is shown in FIG.

In the case of this water tank, a substantially cylindrical body portion 51 is composed of a plurality of reinforced concrete blocks 51a each having the same shape. Therefore, since each block is large enough to be transported by a medium-sized truck, there is an advantage that the transportation cost is firstly low.

[0005] However, there is a disadvantage that the following complicated work is required during assembly on site.

[0006] That is, the block 51a transported to the installation site of the water tank is joined at the site (on the ground) and further subjected to waterproofing to produce the body 51.

The joining process is performed by adjoining blocks 51a by bolting the joining plate 52 to the outer surface of the block 51.
Is temporarily fixed to the outer surface of the block 51a, and after the inside diameter of the body is measured and it is confirmed that a predetermined size is obtained, the main tightening must be performed, which is complicated and requires skill. Moreover, because it is bolted to concrete,
There are difficulties in earthquake resistance. The waterproofing process includes: (a) a step of performing a base treatment (application of a primer) on a waterproof construction site;
(B) filling the joint with a caulking agent; and (c)
The process involves a step of injecting a urethane resin or the like into the joint, which is extremely complicated, requires time to cure the caulking agent, and requires skill.

When the body 51 assembled as described above is swiveled to a predetermined place while being lifted by a crane without a bottom plate, it is settled to a predetermined depth while excavating the ground. At this time, the body 51 sinks while being shaken, so that the body 51 receives an impact. Therefore, there is a problem that if the waterproofing is not sufficient, a gap is generated at the joint.

An object of the present invention is to solve the above-mentioned conventional problems, and to provide a container excellent in earthquake resistance, easy and reliable in assembly, and excellent in waterproofness.
