APPARATUS AND METHOD FOR OBTURATING A TUBULAR WELL

摘要

A disposal apparatus for an abandoned well of underground water using an urethane foam packer is provided to prevent the pollution of underground water and to preserve underground water resources by abandoning a deep well of underground water economically using an urethane foam packer. The disposal apparatus for an abandoned well of underground water using an urethane foam packer contains an urethane material injection pipe(20) inserted to a deep well(10) of underground water to be abandoned, a primary packer(30) and a secondary packer(31) installed on the urethane material injection pipe at regular intervals and expanded when injecting an urethane material to seal up an installation site of the deep well, an impermeable material injection pipe(40) installed to inject an impermeable material to a space between the primary packer and the secondary packer via the primary packer, and an air exhaust pipe(50) installed via the primary packer to discharge air and impurities staying in the space between the primary packer and the secondary packer when injecting an impermeable material through the impermeable injection pipe.
