The invention relates to a construction method of adhesive frozen joints for an existing railway line steel rail in an alpine region. The construction method comprises the following steps: setting up a warm shed on a construction site; mounting a heating furnace in the warm shed; using a blow lamp to heat the steel rail at the joints; coating and brushing an anti-rusting paint on high-strength joint bolts; polishing the steel rail and high-strength joint clamping plates clean; using a die to coat an adhesive on the surface of glass fiber cloth in the warm shed and further sticking the glass fiber cloth on the high-strength joint clamping plates layer by layer; tightly pushing the joints of the steel rail and tightly extruding rail gaps; and bonding the clamping plates with adhesive layers with the steel rail and the like. As for the construction method of the adhesive frozen joints for the existing railway line steel rail in the alpine region provided by the invention, the warm shed is constructed on the construction site, and the heating furnace is arranged in the warm shed, thereby enabling the temperature in the warm shed to achieve the temperature of 18-25 DEG C required for adhesive freezing, enabling the ordinary method for the adhesive frozen joints of the steel rail to be also suitable in the alpine regions, further overcoming the limitations on use and having a positive effect on popularization and application.
