Title:
CONSERVATION METHOD FOR STRUCTURE SUCH AS PAVED ROAD FOR DRAINAGE
Document Type and Number:
Japanese Patent JP3291653
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To carry out road work more easily by adhering an aqueous solution for improvement having the soil configuration comprising cationic organic high polymer to the road surface and then removing dirt with static electricity.
SOLUTION: An aqueous solution of an aggregated agent for improvement of soil configuration 3 comprising cationic organic high polymer is jetted and adhered to the top surface of a paved road for drainage of a road 1, and a dirt 5 adhered to the surface of the paved layer 2 is aggregated by the action of static electricity of the aggregated agent. Next, when rain water or the like is supplied to the layer 2, the dirt 5 is peeled off from the surface of granular aggregates of the layer 2 and flows inside the gap of the layer 2 and then flows out toward the gutter 10. Next, dirty water containing the dirt 5 flowed to the gutter 10 is sucked by a pump 16 placed on a road control vehicle and separated by a separator, and washing water remained in the water tank 14 is stored in a water tank and used again as the aqueous solution of aggregated agent. By doing this, dirt clogged in the gap in a water drain layer can be removed easily without using conventional machines and tools.
