Rock collection pipe well construction method
According to the present invention, a method for constructing a water sampling pipe well in rock comprises: a core excavation member preparation step of fixing a lower end of a foundation well, having the same inner diameter as an underground collecting well for construction and having an outer diameter smaller than that of a ring-shaped core excavation member having a diameter greater than that of the underground collecting well for construction and having a tapered portion tapering to the outside of the inner circumferential surface thereof, to the upper surface of the core excavation member; a surface layer excavation step of excavating a surface layer to a predetermined diameter to form the underground collection well; a core excavation member installation step of vertically installing the core excavation member in a portion excavated in the surface layer excavation step; a core excavation member lowering step of moving the core excavation member in a vertical underground direction by excavating the lower surface of the core excavation member in a state in which the core excavation member is installed; a core excavation member grouting step of blocking the inflow of water between the upper surface of an underground rock layer and the core excavation member by grouting the contact area between the upper surface of the underground rock layer and the core excavation member by using the core excavation member and forms while the core excavation member contacts the upper surface of the underground bedrock layer by repeating a well connection step of connecting a well to an upper portion of the foundation well in a state in which the foundation well is inserted into the excavated portion from the ground; a rock layer excavation step of excavating the underground rock layer in the interior partitioned by the core excavation member; and a water sampling well drilling step of radially forming a water sampling well for sampling bedrock water by using an excavator for a water sampling well. Therefore, the quality of bedrock water can be increased.
