[0002]

2. Description of the Related Art Drainage boxes are installed on a road at regular intervals, and a top made of a drainage box is covered with a grating. In such a grating drainage basin,
If left unattended, a foul odor will be generated, so deodorant equipment using activated carbon is placed inside the drainage basin to take deodorant measures.

[0003]

However, in such a deodorizing device, there is a problem that the activated carbon has to be replaced once a year, so that the cost is high. Also,
In spite of the deodorizing measures as described above, there is also a problem that the deodorizing effect is not obtained so much because the grating lid is used so that the inside of the drainage basin and the ground are in communication with each other. Further, during the winter period, the heat generated from the drainage trench melts the snow around the drainage compartment to form a hole, which poses a problem that it is a dangerous state for traffic.

Therefore, according to the present invention, it is possible to easily prevent a foul odor from being generated from the grating drainage basin, and to prevent the snow around the drainage basin from melting during the winter period to hinder traffic. An object of the present invention is to provide a drainage basin heat insulation deodorizing device and method.
