Title:
DRIVING METHOD OF STEEL PIPE SHEET PILE
Document Type and Number:
Japanese Patent JP3245126
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve construction precision and to solve conventional problems such as delay of a construction period, loss of construction cost, lowering of safety at the time of construction, deterioration of quality, etc., by preventing rotation of a steel pipe sheet pile by setting rotation preventive jigs on both sides.
SOLUTION: A steel pipe sheet pile 30 is driven by using a vibrohammer in a state of setting rotation preventive jigs 50, 50 on both sides. Even if the steel pipe sheet pile 30 is about to rotate due to vibration of the vibro hammer, coupling pipe fixing ports 500, 500 of the rotation preventive jigs 50, 50 set on its both sides restrain a coupling pipe 20 and prevent its rotation. In this case, it is possible to set the rotation preventive jigs 50 on the both sides of the steel pipe sheet pile 30 by previously driving the steel pipe sheet piles 30 with an interval of one each of them each.
