Abstract:
The present invention relates to an infiltration/retention tank for water circulation, wherein not only rainwater introduced by a rainwater infiltration facility installed near the ground surface during a rain, but also spilt groundwater that has infiltrated underground is automatically introduced into the infiltration/retention tank, thereby substantially improving the water circulation ratio. An infiltration/retention tank for water circulation according to the present invention has an automatic groundwater introduction device for an infiltration/retention tank, the automatic groundwater introduction device comprising: a chest-shaped concrete structure (21) installed on a reinforced concrete floor (1) of an infiltration/retention tank laid underground, the concrete structure (21) having a space (20) therein; an underground water introduction passage (22) having the shape of a perforated tube, which is surrounded by a crushed stone aggregate (41) and connected to the inner space (20) of the chest-shaped concrete structure (21); a valve housing (23) for automatically introducing groundwater, which is laid in the reinforced concrete floor (1) of the infiltration/retention tank and connected to the inner space (20) of the chest-shaped concrete structure (21); and a valve (12) for automatically introducing ground water, which is detachably mounted on the valve housing (23) for automatically introducing groundwater so as to automatically introduce the spilt groundwater introduced into the inner space (20) of the chest-shaped concrete structure (21) into the infiltration/retention tank. The infiltration/retention tank for water circulation according to the present invention is advantageous in that, by utilizing spilt groundwater, the effective amount of water can be increased by 150-350% compared with conventional infiltration/retention tanks depending on the groundwater level.
