Patent number: 9658147Abstract: A apparatus for measuring saturated hydraulic conductivity of unsaturated porous media in an unsaturated zone of the earth. The measuring apparatus includes a cylinder member inserted into the porous media in a position in which the upper and lower ends of the cylinder member are open, a means for supplying a constant flow rate of water to the cylinder member, and a pressure measuring means for measuring the hydraulic head in response to water flowing into the cylinder member. The measuring apparatus can easily measure the vertical hydraulic conductivity of a foundation based on Darcy's Law in the field. It is possible to accurately measure the hydraulic conductivity of a sedimentary layer in the natural state and easily determine geological characteristics of the soil. It is possible to obtain very accurate information regarding the process of dispersion and movement of contaminants.Type: GrantFiled: September 10, 2015Date of Patent: May 23, 2017Assignee: KOREA INSTITUTE OF GEOSCIENCE AND MINERAL RESOURCESInventors: Bong-Joo Lee, Ji-Hoon Lee

Patent number: 9274039Abstract: A permeameter for in-situ measurement of saturated hydraulic conductivity is presented. The permeameter includes a chamber fixedly installed into streambed sediment such that the inside of the chamber is filled with a medium, sediment at water-sediment interface. First and second hydraulic head-measuring lines are respectively connected to upper and lower portions of an outer circumferential surface of the chamber, these are designed for measuring a hydraulic head difference of the inside of the chamber. A flexible tube is interconnected the chamber with the storage pipe. A storage pipe is designed to regulate a hydraulic head difference from the chamber and to measure a quantity and a flow rate of water introduced from the chamber under the streambed.Type: GrantFiled: April 10, 2013Date of Patent: March 1, 2016Assignee: KOREA INSTITUTE OF GEOSCIENCE AND MINERAL RESOURCESInventor: Bong Joo Lee

Patent number: 8522629Abstract: The present invention relates to a sequential groundwater sampler and a sampling method thereof, and more particularly, the sampler is constructed with a first pipe, a second pipe, a first cylinder unit and a second cylinder unit. The first pipe plays a role as a container for vacuum sample bottle. The first pipe is fixedly inserted to the second pipe. The second pipe is connected to the two cylinders to be moved up and down vertically while surrounding the first pipe by an advance and retreat of the second cylinder unit. The second pipe plays a role of, passing a syringe needle amounted at the end of a first piston in the first cylinder unit through a rubber plug of a vacuum sample bottle at the bottom end of the first pipe, or separating the syringe needle from the vacuum sample bottle, by an advance and retreat of the first cylinder unit. If the second cylinder and the first cylinder sequentially advance, groundwater is injected to the vacuum sample bottle at the bottom end of the first pipe.Type: GrantFiled: August 26, 2010Date of Patent: September 3, 2013Assignee: Korea Institute of Geoscience and Mineral ResourcesInventors: Bong Joo Lee, Yong Je Kim

Patent number: 8429986Abstract: There are provided an apparatus and method for groundwater sampling, using a hydraulic coupler according to the present invention. In more particular, in the groundwater sampler which is positioned at multiple depths within a groundwater borehole to simultaneously take groundwater samples at the multiple depths, couplers are each connected to both ends of a water sampling pipe made of a metal pipe material. In case of positioning the sampler at a targeted depth, a socket and a plug forming each coupler are connected to each other, so that the both ends of the water sampling pipe—to lead groundwater to freely flow in/out. Thereafter, at the targeted depth, the sockets or plugs are permitted to be separated in the couplers at the both ends of the water sampling pipe by using a lift device, so that the both ends of the water sampling pipe are sealed to simultaneously taking groundwater samples at multiple depths.Type: GrantFiled: October 14, 2010Date of Patent: April 30, 2013Assignee: Korea Institute of Geoscience and Mineral ResourcesInventors: Bong Joo Lee, Kyung Seok Ko
