An underground water extraction device is disclosed. The present invention comprises: an underground water extraction pipe inserted into a drilling pipe for underground development to be connected to an underground water layer underground; an air injection pipe inserted into the underground water extraction pipe, and connected from the inside of the underground extraction pipe to the underground water layer to inject air into the underground water layer; and an air compressor connected to the air injection pipe to continuously inject air with the air injection pipe. No additional pump is installed in an end of the air injection pipe and the end of the underground water extraction pipe to reduce installation costs; and the present invention has low maintenance costs, and is easily managed as a pump is not required to periodically be replaced. |
