PROBLEM TO BE SOLVED: To enhance workability, efficiency and productivity by virtue of rapid performance of work by providing an additional soil spray tank with a radio control device and enabling serial maintenance determining a conduction driving machine of a coupling system structure. SOLUTION: Security, safety, prevention of an accident, the workability, the efficiency and the productivity can be enhanced by the additional soil spray tank which achieves labor savings by centralized operations using radio control, in the cases where operations are stopped by trouble with the additional soil spray tank and where working conditions are full of hazards.
