RESILIENT CUSHION FOR COVER OF UTILITY-PIPE CONDUIT AND CONSTRUCTION METHOD FOR SAME

摘要

The present invention relates to a resilient cushion for a cover of a utility-pipe conduit which is an underground tunnel accommodating various types of cables, gas pipes, and the like; a cover of an improved utility-pipe conduit; and a construction method for a cover of a utility-pipe conduit using the resilient cushion and cover. According to the present invention, reduction in noise when a vehicle passes is possible; and prevention of deformation and breakdown of the cover of the utility-pipe conduit is also possible. The resilient cushion for a cover of a utility-pipe conduit comprises: an upper protrusion head portion which protrudes upwards in a semi-circular shape inserted into the cover of the utility-pipe conduit; an intermediate step integrally connected to an upper protrusion head portion, protruding outwards to be caught by the cover of the utility-pipe conduit; and a bottom recess portion integrally connected to an intermediate step and recessed in a direction of the protrusion head portion to be folded for easy insertion at the time of being inserted to a mold plate to manufacture the cover of a utility-pipe conduit on a bottom thereof, wherein both sides between the upper protrusion head portion and the intermediate step are configured with first side concave grooves.;COPYRIGHT KIPO 2016
