CONTINUOUS CONSTRUCTION METHOD OF REVETMENT, AND METHOD OF WIDENING RIVER OR THE LIKE

摘要

PROBLEM TO BE SOLVED: To provide a construction method for efficiently repairing a revetment of a river or a dike by continuously pressing in steel pipe piles without needing a large-scale temporary device, and to provide a method of widening the river or the like utilizing the construction method.;SOLUTION: In this continuous construction method of the revetment, equipment such as a crane is arranged ready to work on a steel pipe pile line PL, and the steel pipe pile line PL is constructed at the concrete revetment using a steel pipe pile press-in device 11 capable of rotationally pressing in the steel pipe piles P. While obtaining reaction from the steel pipe pile line PL, the steel pipe piles P are rotationally pressed in to construct a continuous wall. The continuous wall is constructed using this method, and then a working device or the like for carrying out widening work is disposed near the steel pipe pile line PL to remove sediment or the like on the river side or to dredge the nearby water bottom.;COPYRIGHT: (C)2005,JPO&NCIPI
