PURPOSE: A pressing plate fixing structure for reinforcing a structure base is provided to prevent ground disturbance and to check internal force of micro-pile in real time. CONSTITUTION: A pressing plate(20) fixing structure for reinforcing a structure base comprises: a bottom plate(30), a core hole(35), a micro-pile, and a hydraulic cylinder. The core hole is vertically punched at the bottom plate. The micro-pile is mounted at the core hole. A plurality of sub core holes(36) are punched around the core hole along the columnar direction. The coupling part of a first nut is fixed using concrete.

PURPOSE: A structure lifting apparatus using insertion and excavation and a structure lifting method using the same are provided to easily lift a structure by easily inserting an insertion body into the bottom of the structure. CONSTITUTION: A structure lifting apparatus using insertion and excavation comprises a reaction support body(200), an insertion body(300), an insertion unit(400), a lifting unit, and an excavator(600). The reaction support body is composed of a pair of box bodies. The box bodies are separated from each other to form an inner space(S) in the bottom plate(110) of a structure(100). The insertion body is set in the inner space and is inserted into the ground through the bottom plate of the structure. The insertion unit comprises lower and upper insertion blocks(420,430), an insertion block connection member(440), and a pressure jack(410). The insertion block connection member connects the lower and upper insertion blocks to each other. The pressure jack presses the lower insertion block downward. The excavator excavates the ground around the front end of the insertion body using an excavation bit(610). [Reference numerals] (AA) Support protrusion
摘要:
An energy anchor is provided to use geothermal energy inside or around the anchor by installing a geothermal heat exchanger on a perforation hole for installing the anchor or an installation hole in which the anchor is installed. In an energy anchor, a geothermal heat exchanger(1) is installed at a perforation hole for installing an anchor(3) and an installation hole(5) in which the anchor is installed. The anchor comprises a rock anchor, an earth anchor, a buoyancy preventive anchor, a rock bolt, and a soil nailing. The geothermal energy around or inside the anchor is used through the geothermal heat exchanger installed at the perforation hole or the installation hole.
