PROBLEM TO BE SOLVED: To save labor and expense for exchanging work and to make it possible to simply burn up by providing the cylindrical part of a buried bracket having a tube part, a bottom part and a rotation checking member fitted to the tube part with a burnable pole. SOLUTION: A buried metal bracket 4 is buriedly provided in the earth G, and a pole 1 is inserted in the tube part 3a of the bracket 3. Next a gap 4 is formed between the inner periphery of the tube part 3a and the outer periphery of the inserted pole 1, and a sealing agent 5 such as a silicon sealant is applied in the upper end of the gap 4. In the case of the damage of the pole 1 or the exchange of a control sign for a different one, after removing of a sealing agent 5, a damaged pole 1 or the like is drawn out of the tube part 3a of the bracket buried in the earth G. After that, a new pole 1 is inserted into the tube part 3a, and the sealing agent 5 is applied in the upper end of the gap between the inner periphery of the tube part 3a and the outer periphery of the pole 1. Thus, the invasion of rain and a dust into the tube part 3a and the easy drawing off of the pole 1 can be prevented, and the working ability of the execution of a traffic control sign can be improved. |
