H-SHAPE STEEL PILE AND ROTATIONAL PENETRATION METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To make practical use of an H-shape steel pile weak in torsional rigidity compared with a steel pipe pile while being reducible in cost in view of problems in the structure of fitting the end shoe of a short steel pipe to the lower end of the H-shape steel pile, wherein members such as the short steel pipe and screw blades are required and many machining man-hours are required to increase a construction cost, which results in making no great difference from using the steel pipe pile, and in an existing example of welding the screw blades over the whole flange part region in the width direction of the H-shape steel pile, wherein the embrittlement of the H-shape steel pile caused by a weld burn is unavoidable. ;SOLUTION: This H-shape steel pile 1 is provided with inclined guide blades 5 stuck across both side flanges 9, 9 of H-shape steel. The inclined guide blades 5 are provided in units of two to four parallel slanting blades. A bridge plate 14 is directly fitted between the flanges 9, 9 by welding, or the inclined guide blades 5 are provided at a square pedestal plate stuck between the flanges 9, 9.;COPYRIGHT: (C)2003,JPO
