A Mobile Stream Diversion System for Hazardous Materials Spills Isolation

摘要

A program was conducted to design and develop a prototype mobile system for quick diversion of a stream flow around a contaminated area. Spill scenarios were analyzed to establish design criteria for a self-contained, independent system that would maintain flow continuity around a region undergoing decontamination. The design utilized stock items available nationwide, to provide easy maintenance and replaceability. To provide flexibility and reliability, the system was assembled as two independent units, mounted on trailers so that spills would be readily accessible via state or interstate highways. A quick unloading feature provided capability for air shipment to more distant locations. Once onsite, the system could be assembled and placed in operation by a crew of five in a matter of hours. Unit operation and ability to deliver a flow rate of 0.35 m3/s a distance of 0.3 km over unprepared ground were evaluated in a shakedown test.
