METHOD AND DEVICE FOR DISPENSING DEICING LIQUID AT FIXED POSITION

摘要

<P>PROBLEM TO BE SOLVED: To provide a method and a device for dispensing a deicing liquid at a fixed position. Ž<P>SOLUTION: A large number of spraying spots are provided on a roadway surface for spraying the deicing agent on a traffic road surface. Since these spraying spots are spraying bodies embedded in the paved surface of the roadway, a vehicle can pass over the spraying spots. Each of the spraying bodies ejects two deicing agent jets 2 and 3 in an illustrated embodiment or 2 and 3' in the other embodiment. These deicing-agent jets are ejected obliquely to traveling directions of each lane. A plurality of spraying bodies are supplied with the deicing agent through a plurality of pipes 4 and 5. These pipes are extended to each spraying body at the side of the roadway or in the paved face of the roadway. A tank 6 for the deicing agent is installed for the deicing agent. A plurality of the pipes 4 and 5 communicating with the respective spraying bodies 1 are supplied with the deicing agents from the tank for the deicing agent by a pump 7.
