MOMOTANI YOSHITSUGU / NAKAMURA TAKAHISA / NOMURA SEIJUN

PROBLEM TO BE SOLVED: To provide a method for preventing flowing of ballast for a track by using an inexpensive polymer aqueous solution that enables easy execution of work and track repair.SOLUTION: A method for preventing flowing of ballast for a track by using a polymer aqueous solution includes the steps of: (a) forming a water-soluble reaction agent in which a reaction agent is dissolved in water; (b) spraying half of the water-soluble reaction agent on the ballast; (c) spraying the polymer aqueous solution, in which a biodegradable polymeric material is used as a principal ingredient, on the ballast on which half of the water-soluble reaction agent is sprayed; and (d) spraying the rest of the water-soluble reaction agent in the step (b).SELECTED DRAWING: Figure 1
