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.

Abstract: A method and apparatus for a board game for two to four players relating to highway construction, the object of which is to be first to complete the sequence of operations of a highway construction project. An inner track on the game board depicts the operations of the construction project which must be completed in sequence by purchasing the necessary equipment for each operation.
