DYNAMIC BARRIER USED TO SOLVE A LARGE CONSTRUCTION DEWATERING PROBLEM

This paper provides a description of a dynamic barrier installed between a railroad trench under construction and an existing toxic plume floating on the surface of groundwater adjacent to an oil recycling facility. The Alameda Corridor Transportation Authority, in April 2002, completed construction of a 32-km railroad transport project that ranks as one of the largest freight transport projects ever undertaken. 16 km of surface tracks and a 16-km below-surface trench section along Alameda Street were constructed. The trench portion will carry 2 railroad tracks beneath existing streets. During trench construction, significant quantities of toxic waste were encountered in soil and groundwater from adjacent facilities. This paper describes one such occurrence and the solution selected to avoid costly construction delays while providing for environmental safeguards.
