A feature of the present invention is a catch basin attachment to be suspended from a crane and inserted beneath bridge decks during demolition of a bridge deck to catch crushed concrete and pieces of reinforcing bars in such bridge deck removal and demolition operations.
The crane suspending the basin may be located on a river bank adjacent the bridge being repaired or on a barge below the bridge, as well as being located on a truck on the bridge or on a road passing under the bridge.
An open end 30 of the tray-like basin 11 is formed by a pair of distal oblique lateral edges 31, 32 of respective sidewalls 15, 16 and by a distal substantially horizontal lateral edge 33 of the floor 19.
Underwater inspection of se ven bridges using both scuba and hard hat surface supply diving to inspect for the presence of scour, evaluate the foundation integrity and confirm the rehabili tation of structures.
The bridge was 77-feet in width with the continuous superstructure being AASHTO, Type IV I-beams and the simple spans being steel plate girder to accommodate the truss center span.
Survey of 3500 feet of approach roadway, bridge measurements, preparation of right-of-way documents and design of the roadway approaches along the Belt Parkway for the total rehabi litation of 520 foot long, 105 foot wide eleven span bridge carrying six lanes of the Belt Parkway over Gerritsen Inlet in Brooklyn, New York.
