Adjustable casting die for high-position pool

The utility model belongs to building construction equipment, and particularly relates to an adjustable casting die for a high-position pool, and a reinforced concrete chimney in an electric power construction project is a high-rising building and a landmark building of the whole power plant project. In the chimney building process, vertical transportation of reinforced concrete chimney construction is the main process in the whole construction, the problem that vertical transportation mostly adopts a slip-form construction process is solved, automation is achieved, and when concrete is solidified, the distance between an outer mold and an inner mold can be increased by starting a first motor; at the moment, the solidified concrete cannot be scratched in the rising process, and the surface cannot be damaged; when different buildings with different diameters are cast, the first motor can be started for adjustment; and along with the increase of the casting height, materials on the ground can be conveyed to the
