APPARATUS AND METHOD FOR DIGGING WELL BY RECYCLE UNDER GROUND WATER

摘要

The present invention relates to an eco-friendly excavation apparatus and method for groundwater and geothermal resources through recycling of excavated effluent water, and more particularly, to an excavation apparatus and method for excavating an underground excavation hole (all holes in the ground such as underground water wells, In the excavation process, the mixed water drainage water discharged from the excavation process is sorted by type on the ground and the separated groundwater is re-injected into the excavation hole or other excavation hole to remove the contamination of the surrounding river due to excavation drainage. And to preserve the environment. The eco-friendly excavation drilling apparatus for ground water and geothermal resources through excavated drainage recirculation injection according to the present invention is characterized in that excavation bit, at least one connection rod connected to the excavation bit, and excavation is performed by rotating the excavation bit through the connection rod (10) which is formed on the connection rod and includes an air compressor for injecting high-pressure air and punctures the digging hole in the ground; An underground water separator (20) for separating the slurry discharged from the excavator into groundwater and slurry; (30) for re-injecting groundwater selected through the underground water separating tank into the excavation hole, wherein the pressurizing means includes a pressurization pump (31) for pressurizing groundwater separated from the slurry through the underground water screening tank, A pressurization injection pipe (32) connected to the pressurization pump for injecting groundwater under pressure fed by the pressurization pump into the excavation hole, an injection port for removably connecting the pressurization injection pipe And a tube support.
