Technical Examples

This invention refers to a method for removing a part of concrete construction that comprises a base concrete; a reinforced concrete formed on the base concrete; rebars embedded in the base concrete and upwardly extending through the reinforced concrete; the method comprising the steps of: forming a slit in the reinforced concrete and disconnections at an intermediate of the rebars; applying an expansion force on opposite surfaces of the slit in the reinforced concrete to simultaneously break a boundary plane of the reinforced concrete; and removing the moved portion of the reinforced concrete from the base concrete as a scrap. Also, the present invention provides a flat jack suitable to break boundary planes of the scrap wherein the flat jack comprises two metallic plates joined to each other, and an inlet for introducing into the jack pressurized fluidic material to inflate the jack in order to produce a great expansive force.
