摘要： An inflatable collection basket, tethered from a bridge superstructure, and including an airline leading thereto. Upon introduction of air into the deflated mechanism, the basket inflates to define a four sided cone having an upper inflated wall portion, descending to a centrally located port, wherein a recovery line leads into for retrieval of the waste and cuttings. There is further included a plurality of inflatable "fingers" extending from each of the corners of the upper border of the cone down to the lower ring, for defining the rectangular cone wherein the cuttings would flow. The cone further includes a material layer around its interior, for serving to confine any cuttings which fall into the cone and flow the cuttings down into the retrieval line. Upon inflation of the cone border and the plurality of fingers, the cone, would be elevated to a position adjacent the superstructure to be sandblasted, and the upper border of the cone would be secured to the superstructure via a plurality of lines or the like therefore securing the upper border of the cone against the superstructure. In other embodiments, the cone may be rectangular shaped or include a pair of cones, to cover a broad area. The retrieval line would be attached to a vacuum pump or the like so that any of the materials falling into the retrieval cone would immediately be suctioned out of the cone through the line and into a retrieval tank or truck located away from the blasting site.
