Pipeline thermal insulation material mounting tool and using method thereof

The invention provides a pipeline thermal insulation material installation tool and a using method thereof.The installation tool comprises a steel plate piece capable of being flexibly bent, a plurality of rib rods arranged in parallel are arranged on the steel plate piece and arranged in the curling direction of the steel plate piece, and the same side end of each rib rod is hinged to a pressing rod; the length of the pressing rod is equal to that of the rib rod; the hinged ends of the rib rods exceed the edges of the steel plates, so that each pressing rod can rotate around the hinged shafts to approach the rib rods; a push-pull handle is arranged on the edge of one side, close to the hinge shaft of the pressing rod, of the steel plate piece. According to the mounting tool, the thermal insulation material is compressed and deformed, then the thermal insulation material is pushed into the gap between the through-wall steel pipe and the sleeve along with the mounting tool, and then the mounting tool is withdr
