SUCTION APPARATUS FOR CLOGGING SUBSTANCE IN PAVEMENT, REMOVING DEVICE FOR CLOGGING SUBSTANCE IN PAVEMENT AND FUNCTION MAINTAINING CAR FOR DRAINING PAVEMENT

摘要

PROBLEM TO BE SOLVED: To provide a sucking apparatus for clogging substances in a pavement efficiently sucking and removing the clogging substances penetrated into the voids of the pavement. ;SOLUTION: The sucking apparatus 120 for the clogging substances to the pavement has generating sections 121 and 122 generating a swirling current ascending from a road surface at negative pressure generated by a negative pressure generator 110 and an air supply section 123 supplying air swirling along the interior-wall surfaces of the generating sections 121 and 122 and promoting the generation of the swirling current. Negative pressure is increased by promoting the generation of the swirling current, and the clogging substances clogging in the voids of the pavement are sucked.;COPYRIGHT: (C)2004,JPO
