摘要 |
<P>PROBLEM TO BE SOLVED: To provide a vertical drainage channel structure with a small animal intrusion preventive function for preventing a small animal from intruding into an expressway along a vertical drainage channel arranged on a slope of the expressway. <P>SOLUTION: The vertical drainage channel structure is formed by combining an inclined vertical drainage channel 10 formed on the slope 20 between the expressway 21 and a general road 22 existing at a position lower than that of the expressway, and a channel cover 1 placed at the vertical drainage channel 10. A shielding screen 2 rotatable in a longitudinal direction of the vertical drainage channel 10 and downward only is hung from a rear face of the channel cover 1. The shielding screen 2 comprises a rotary shaft 3 and a plurality of plate members 4 arranged at equal intervals like a bamboo blind. The plate members 4 are longer than the depth of the vertical drainage channel 10, and the shielding screen 2 is restricted from rotating upward. <P>COPYRIGHT: (C)2011,JPO&INPIT |
