Abstract

A device for capturing and removing substantially all debris that falls into a manhole includes a flexible, substantially circular folded disk that is inserted into the manhole prior to performance of the debris-creating work, and is unfolded by an unfolding mechanism until the rim of the disk rests against the manhole bounding wall. Semi-rigid rods are secured to eyelets adjacent to the perimeter of the disk and terminate above the disk at a common junction, to which a removal and insertion mechanism can be attached. The device may be left inside of the manhole, separated from the insertion and removal mechanism, during performance of the debris creating work, and then folded and removed after the work is completed, thereby trapping and removing the debris. In embodiments, the unfolding mechanism includes supports radiating outward from the center of the disk and attached to the disk along their entire lengths.
