In recent years, with the increase of buildings and the increase of the packing rate of the surface, the tendency of the rainwater to flow directly into the sewer or the river without infiltration into the underground is increasing. In addition, flooding may occur if the flow rate to the sewer or river exceeds the allowable amount due to the amount of precipitation. On the other hand, if the amount of water penetrated into the ground is small, the underground water becomes insufficient. This causes problems such as the drought, and the water quality of the river is reduced due to the dry season.

In recent years, a rainwater storage tank capable of storing rainwater and allowing it to flow out into a river when necessary is provided.

The rainwater storage tank as described above has a method of installing concrete by placing concrete on site and a method of assembling the manufactured concrete storage blocks in the field. However, the method of constructing the concrete by installing the concrete on the site increases the construction time, increases the construction cost, and increases the probability of occurrence of the safety accident.
