A reservoir water system and thereof installation method for groundwater inflowing into the reservoir

摘要

An installation method of a water storage system for inflow of underground water into a storage tank is disclosed. The water storage system according to the present invention comprises: a storage tank which is provided in the ground; and a water collection unit which is positioned at a lower portion of the storage tank and collects surrounding underground water. The storage tank includes a plurality of frame blocks which are assembled and laminated, reinforcement members which are inserted along the inside of struts provided in the frame blocks, and a blocking sheet which surrounds the storage tank. The reinforcement members are formed to be extended to the inside of the storage tank and the water collection unit while penetrating the blocking sheet surrounding the storage tank and are configured in a pipe shape having a hollow inner portion such that underground water flowing into the water collection portion moves upwards. The underground water flows upwards along the inner passage of the reinforcement member when buoyancy is generated in the storage tank by the underground water flowing into the water collection unit.
