To provide a work-execution method and a work-execution device for a road surface sign line having water permeability, and indicating superior drainability even when executed on drain pavement, by supplying a proper quantity of paint for executing the road surface sign line, by regulating the excessive outflow of the paint even on an inferior road surface and the draining pavement.
This work-execution method of the road surface sign line, constructs the road surface sign line 3 by continuously forming a state of supplying no excessive paint to an outflow port 5, by using a device as a construction device having a paint hopper 1 for storing the heated and melted paint 2, a coating film thickness regulating plate 4 installed on the lower end of a paint hopper rear surface, the outflow port 5 formed of the lower end of the coating film regulating plate 4 and a lower opening part of the paint hopper 1, and a delivery quantity adjusting tank 6 arranged in the paint hopper 1 above the outflow port 5, that is, the delivery quantity adjusting tank 6 arranged so as to form a space between the outflow port 5 and the delivery quantity adjusting tank 6.
