The present invention relates to a water collecting facility that collects and stores ground water, and has a storage tank (20) supported on the basis of hollow piles (10) on top of a plurality of hollow piles (10) located in aquifers (층 水 層). Then, the water supply pipe 30 connected to the pump 35 is installed in the hollow pile 10, the groundwater introduced into the hollow pile 10 is pumped to the water supply pipe 30 is stored in the storage tank (20).

지하수 취수 시설은 대수층의 구조 등 지반 여건을 고려하여 다양한 방식으로 구축될 수 있는데, 대수층 상측에 불투수층이 형성된 피압대수층의 경우 관정(管井) 형식이 주로 적용되고, 상대적으로 취수 심도가 깊지 않은 자유수면 대수층의 경우 집수정(集水井) 형식이 주로 적용되며, 이러한 지하수 취수 시설 관련 종래기술로는 특허 제690396호를 들 수 있다.
Underground water intake facilities can be constructed in various ways in consideration of the ground conditions such as the structure of the aquifer.In the case of the aquifer aquifer with an impermeable layer formed above the aquifer, the well type is usually applied, and the free water surface has relatively low intake depth In the case of aquifers, a sump type is mainly applied, and the prior art related to the groundwater intake facility is Patent No. 690396.

특허 제690396호에서와 같이, 방사상(放射狀) 집수정으로 대표되는 종래의 자유수면 대수층 지하수 집수 시설은 광범위한 지역에 함양된 지하수를 효율적으로 취수할 수 있는 장점이 있으나, 시공 및 유지관리에 있어서 다양한 문제점을 가진다.As in Korean Patent No. 690396, the conventional free water aquifer groundwater collecting facility represented by a radial water collecting well has an advantage of efficiently collecting groundwater contained in a wide area, but in terms of construction and maintenance, There are various problems.
