APPARATUS FOR PREVENTING LANDSLIP INFLOW OF STEEL PIPE AND STEEL PIPE PROPULSION METHOD OF CONSTRUCTION USING THE SAME |
摘要 |
PURPOSE: A device for preventing soil flow into a steel pipe in a landslip and a pipe ramming method using the same are provided to prevent soil flow into a large diameter steel pipe in a landslip by performing hilling in a safe hilling position while checking a hilling guiding part. CONSTITUTION: A device for preventing soil flow into a steel pipe in a landslip comprises a hilling guiding part (100) formed on the inner circumference of the front end of a steel pipe or the inner circumference of a leading pipe. The hilling guiding part guides a safe hilling position in which soil does not collapse in the hilling into the steel pipe or the leading pipe. The hilling guiding part functions as a stopper in order to prevent soil flow into the pipes in a landslip. The hilling guiding part is moved in the longitudinal direction of the steel pipe and the leading pipe. The hilling guiding part includes a guide rail (110) and a carrying body (120). |
