And holes are punched at the positions corresponding to the bolt holes on the outer surface of the arc-shaped cone, the tail end parts of the pulp blocking plates are bent inwards by 90 degrees, one end of the cavity is blocked by the bent parts, and the lengths of the bent parts at the tail parts of the two pulp blocking plates are equal. The end part of the conical core is provided with a conical core circular ring for disassembly.

When the climbing cone is installed, a proper amount of lubricating oil is coated on the surface of a thread to reduce friction, then the cone core is fixed between the two arch-shaped cones under the action of the thread, then the outer part of the slurry blocking plate is fixed through the bolt, the middle part and the tail part of the slurry blocking plate are fixed through the binding wire, and proper glue is coated at the joint of the slurry blocking plate and the arch-shaped cones to further prevent concrete slurry from flowing in.

The utility model has the following advantages:

the cone core is positioned between two arch cones, the cone core is in threaded connection with the arch cones, the slurry blocking plate is fixed between the two arch cones, and a cavity is formed among the cone core, the arch cones and the slurry blocking plate. The friction force when the climbing cone is pulled out is converted into the axial action for overcoming the bonding action of concrete so as to achieve the aim of convenient disassembly.
