ABSTRACT:
A well device comprising a vertially installed suction pipe and a plurality of horizontal water collecting pipes horizontally provided in a water layer, the horizontal water collecting pipes being provided with a number of water collecting holes. With this construction, a sufficiently large area of water collecting holes may be obtained and a flow speed of groundwater is reduced and therefore, a loss of well does not occur, entry of earth and sand is prevented, dewatering of the water layer is restricted, and durable years of well may be considerably increased.
