In general, with the increase of buildings and the increase of the land surface pavement rate, rainwater frequently flows into sewers or rivers during rainy season during heavy rains during rainy season.

Exceeding the allowable inflow of rainwater causes flooding leading to flooding of roads and flooding of houses and buildings. On the contrary, when the inflow of rainwater decreases, the water quality of the stream deteriorates. There is a problem of depletion, and a technique has been developed for a storage tank for temporarily storing the above rainwater in the basement to adjust the amount of outflow into the river.

As a technology of such a storage tank, in the case of an excellent storage tank (patent registration number 485742) filed and filed by the applicant, the pillars are provided at right angles at four right angles at the front, rear, left, and right sides of the top plate and the bottom plate, respectively. Openings are formed on four surfaces by the plurality of holes, and through holes are formed in the upper and lower portions of the pillars, respectively, and through holes are formed in the inner side, respectively, and the plurality of grooves in which the couple guide pins are inserted, respectively.
