SHIELDING DEVICE AND SHIELDING METHOD FOR PREVENTING INFLOW OF POLLUTED UPPER GROUNDWATER AND FOR BLOCKING SECTION
The present invention relates to a shielding device and a shielding method for preventing the inflow of polluted upper groundwater and for blocking a section, wherein the shielding device is used in order to prevent the inflow of polluted upper groundwater by using the advantages of an expansion tube and a compression tube such that shielding is enabled similar to the compression tube even though the expansion tube is damaged like the expansion tube, and that a shielding function can be obtained by an autonomous operation even if a lower end of a casing does not come in contact with the bottom of a borehole, and also, a section is capable of being blocked even in a middle position of the borehole. One or more shielding devices of the present invention, for preventing the inflow of polluted upper groundwater and for blocking a section, can be provided in a casing by comprising: a compression tube (20) which is provided on the circumferential part of the casing installed inside an underground borehole (1), and which is compressed so as to come into close contact with a hollow wall of the borehole by an external force; a spring for enabling the compression tube to come into close contact with the hollow wall of the borehole so as to seal the upper and lower parts around the compression tube; and a release means (40) which fixes the spring in a state of an elastic force opposite to an elastic force for enabling the compression tube to come into close contact with the hollow wall of the borehole, and which releases the fixed spring so as to generate the elastic force for enabling the compression tube to come into close contact with the hollow wall of the borehole.

GEOTHERMAL COIL PIPE HEADER DEVICE, VERY DEEP VERTICAL CLOSED-TYPE GROUND-COUPLED HEAT EXCHANGER USING SAME, AND METHOD FOR INSTALLING THE HEAT EXCHANGER
The present invention relates to a very deep vertical closed-type ground-coupled heat exchanger that uses geothermal energy without taking in underground water, and to a method for installing the heat exchanger. More particularly, an anchor connected to a rope is disposed in a very deep geothermal excavation hole formed to use geothermal energy, then a header device is installed on one end of a U-bend geothermal coil pipe, then the geothermal coil pipe is coupled to the rope, and then the rope is pulled and wound using a winch on the ground. Accordingly, the U-bend geothermal coil pipe, which is made of polyethylene (PE) and has poor rigidity, can be forcibly inserted down to the very deep bottom of the geothermal excavation hole, thereby increasing the heat transfer area of the heat exchanger.
