Underground water level observation device

摘要

A groundwater level observation apparatus is provided to confirm the level of the groundwater by observing the groundwater flowed through a groundwater inlet through a transparent tube. A groundwater level observation apparatus comprises: a manhole connecting part(10) combined in a part of a manhole; a groundwater inlet(20) which is formed in the front of the manhole connecting part and is buried in the soil; and a transparent tube(40) perpendicularly installed at the behind of the manhole connecting part. In the groundwater inlet, a plurality of through-holes(22) are formed to flow the groundwater in.
