发明名称 STATIC PRESS-IN METHOD FOR SHAPE STEEL
摘要 PURPOSE:To enable economically superior static press-in of a shape steel with high working efficiency, by a method wherein, when the shape steel is pressed in, a lubricant, such as suspension of clay mineral, is fed by pressure through a piping, and is discharged into a space between the recess surface of the shape steel and bedrock therearound. CONSTITUTION:A 2-piece set of steel sheet piles 4 are respectively formed with a recess part 4a, a web 4b and a flange 4c. A elbow 10 for piping is secured to the inner surface of the web 4b at the lower end of the steel sheet pile 4 in a manner that the one opening 10a is turned upward and the other opening 10b is turned sideward. A piping 12 is extended upward along the sheet pile 4, and is coupled to a flexible hose 14 connected to a grout pump 13. A lubricant, such as suspension of clay mineral, high water absorption properties high molecular water dispersion forming a granular elastic material, is fed by pressure with the aid of a pump 13. This prevents arising of a problem in which the ground therearound is sunk, and sharlpy improves the working efficiency of a free-vibration and free-noise static press-in method.
