Sleeper renewal method for wooden sleeper installed on concrete bed

摘要

The present invention relates to a replacement construction method for converting a wooden sleeper turnout installed on a concrete road to an RC sleeper turnout, the object of which is to minimize the movement of the rail and removal of the concrete road, while minimizing the movement of the concrete road, and a wooden sleeper installed on the concrete road It is to provide a replacement construction method that can be replaced with a sleeper. The present invention for this purpose is to dismantle the fastening device that binds the wooden sleeper and the rail of the wooden sleeper turnout installed on the concrete road (S10); Removing the wooden sleeper and the dustproof box (S20); Chipping the bottom and side surfaces of the grooves exposed due to the removal of the wooden sleeper and the dustproof box (S30); Applying a new and old concrete adhesive to the inner surface of the groove and the bottom surface of the RC sleeper to be newly installed (S40); Arranging the RC sleeper under the rail using the space between the groove and the rail, and binding the RC sleeper and the rail with a fastening device (S50); Installing on the concrete road so that the binding tools that limit the movement of the reinforcing bar strands protruding to the left and right sides of the RC sleeper are located on the left and right sides of the RC sleeper (S60); And after the installation of the fastening tool is completed, injecting the super fast light mortar into the groove, but placing the super fast light mortar so that the super fast light mortar rises to the road surface on the concrete road (S70); on the concrete road, characterized in that it consists of Provides a replacement construction method to change the installed wooden sleeper turnout to an RC sleeper turnout.
