SAND CUSHIONED RAFT FOUNDATION FOR RETROFIT ELECTROSTATIC PRECIPITATORS IN THERMAL POWER PLANTS TO AVOID DISMANTLING OF EXISTING FOUNDATIONS

摘要

A sand cushioned raft foundation (1) for retrofit electrostatic precipitators comprising - a sand cushion (2) provided over existing foundation footing (4), - a plurality of pedestals (6) which support the columns of the retrofit electrostatic precipitator and - a cantilever (5) from an outer pedestal (6), characterized in that the said raft foundation makes installation of retrofit electrostatic precipitators possible without dismantling of existing foundations.
