摘要

PURPOSE:To correct the position of a pipe buried under the ground by movement by a method in which a vibrator is set in the pipe being buried and vibration is applied by the vibrator to the pipe to cause a fluidizing phenomenon is the surrounding soil of the pipe. CONSTITUTION:In case where the surrounding soil layer B of a pipe is not saturated with water, water is supplied through a pipe P to the soil. A vibrator 1 is moved by wire, etc., and a regulating arm 5 is jacket up through a hose 11 by oil pressure, whereupon a contact part 6 comes into contact with the top ceiling of the pipe. When power is applied to a vibrator 4 to generate vibration, the pipe A is vibrated through a plate spring leg 3 and the contact part 6 to give the vibration to the soil layer B. The soil layer B saturated with water is then fluidized, heavy objects such as stone, etc., in the soil settle down, and the sunken pipe A floats slowly up to the position of level L.
