The present invention relates to a hydrant system that is projected over the ground while being buried in the underground. The hydrant system comprises a sluice valve (20) connected to a water-guide tube (10) within a manhole M, the sluice valve having a first opening/shutting shaft (21) disposed therein; a female cylinder (30) having a drain valve (31) that is opened when the sluice valve (20) is locked and that is locked when the sluice valve (20) is opened, and a bracket (36) having a through-hole; a male cylinder (40) having a piston (45) for opening/shutting the bottom of the male cylinder (40) as a piston rod (44) is rotated in the forward or reverse direction; a rod (50) for limiting a projection range of the male cylinder (40) protruded against the female cylinder (30); a manhole cover (60) having a sub hole (62) through which the male cylinder (40) passes; a second opening/shutting shaft (61) for rotating the first opening/shutting shaft (21); and a universal joint (70), which connects the first opening/shutting shaft (21) and the second opening/shutting shaft (51). |
