APPARATUS AND METHOD FOR EXCAVATING DEEP WELL

摘要

The present invention relates to a deep well excavation apparatus and a deep well excavation method. The deep well excavation apparatus includes: a cylindrical well which is empty; a support plate which is pressurized and supported on an inner diameter of an end part of the well; an upper support part to support an outer diameter of the well on the ground; a water supply part to supply water into the well; a bit module which is rotatably supported on the support plate by being extended through a center of the support plate, and has an excavation head excavating the land; a water spraying part to spray water in the well to an excavation surface through the bit module; a protruded bit which is installed at the bit module, and can move between a protrusion position protruded in a circumferential direction rather than a side end part of the excavation head and an accommodation position in the side end part of the excavation head; a sludge exhaust path which is extended through the support plate to exhaust an excavation sludge; and a sludge exhaust pump to provide an exhaust pressure to exhaust the excavation sludge while being installed closely to the support plate. According to the configuration, the present invention can provide the deep well excavation apparatus and the deep well excavation method wherein an excavation driving part can bury a facility capable of performing stable power delivery and storing water closely to the excavation surface at the same time as the excavation, while preventing collapse of an inner wall of an excavation hole.
