摘要： PROBLEM TO BE SOLVED: To provide a construction method of a screw pile for improving efficiency of screwing-in intrusion, reducing rotation torque greatly, and obtaining large tip supporting force and to provide the screw pile used in this method.
SOLUTION: In this construction method for giving rotation force to a pile body 1 by a pile driving machine 30 by utilizing wood screw action of a blade 10 fixed substantially to a tip part of the hollow pile body 1 and ground digging action of an auger 20 and giving rotation force to a head part of the auger 20 to penetrate a pile into the ground by rotating it, a motor for rotating the pile and a motor for rotating the auger can rotate in the opposite directions to each other. When a tip part of the pile body 1 reaches a part close to a supporting layer, the auger 20 is inserted into the pile body 1 to give rotation force to the auger 20. A hardening fluid material is injected into the supporting layer from an auger head 22 while the pile body 1 rotates to stir and mix sediment and the hardening fluid material up to a predetermined depth, and then the pile body 1 is left and the auger 20 is pulled out to solidify sediment softened in accordance with elapse of time.

摘要： PROBLEM TO BE SOLVED: To provide an execution method of a screw pile and the screw pile used therefor capable of promoting efficiency of screw penetration, at the same time, greatly reducing rotational torque and obtaining high front end bearing force. SOLUTION: An execution method of a screw pile is so constituted that operation as a wood screw of a wing 10 fixed to the front end of a hollow pile body 1 and ground excavation softening operation of an auger 20 inserted into a hollow section of the pile body 1 are used to provide torque to the pile through a motor 32 to rotate the pile in the ground to penetrate. In that case, the motor 32 has two rotary shafts capable of rotating them in the opposite direction each other, one rotary shaft is connected to a pile head section, the other rotary shaft is connected to the auger head to rotate them, and hardening fluid is spouted from the auger head 22. Earth and sand and hardening fluid are stirred and mixed by the rotation of the wing 10 and auger head 22, and when stirring and mixing up to a specific depth are completed, the pile is left behind to pull out the auger 20, and earth and sand softened with the elapse of time are solidified.

摘要： PROBLEM TO BE SOLVED: To expand a screw type steel pipe pile in diameter and to improve its function and execution property by connecting a large-diameter upper steel pipe with a specific outer diameter size to the upper end of a lower steel pipe having vanes at the tip section. SOLUTION: An upper steel pipe 3 having the outer diameter 1.15-1.6 times the outer diameter of a lower steel pipe 2 and 60-90% of the outer diameter of vanes 10 is connected to the upper end of the lower steel pipe 2 provided with the vanes 10 at the tip to form a screwed type steel pipe pile 1. When the pile 1 is rotated and intruded into the ground, the sediment below the vanes 10 is moved to the outer periphery of the pile 1 and compressed, however the pile 1 is intruded without receiving large frictional resistance because the gap water pressure is increased immediately after stirring, then the shearing resistance of sediment is recovered by the recovery of the soil grain bonding strength and the reduction of gap water pressure, and the peripheral frictional force is increased. Or, the steel pipe 3 welded with an inverse truncated conical short tapered steel pipe may be welded to the driven steel pipe 2 at the site. Intrusion torque can be reduced, a pile head section can cope with large bending moment, and the bending stress and horizontal displacement quantity at the time of an earthquake can be suppressed.

摘要： PROBLEM TO BE SOLVED: To inexpensively apply a head part expanded steel pipe pile in design execution work by forming an outside diameter of an upper steel pipe in an outside diameter or less of a blade, and setting an outside diameter of a joining member almost equal to the outside diameter of the upper steel pipe. SOLUTION: Steel blades 11a, 11b are placed on an installing part by covering a tip opening part of a lower steel pipe 2 to be slantingly installed in the mutually opposite directions by welding to constitute a blade 10. In that case, an outside diameter D2 of an upper steel pipe 3 is set to about 1.15 to 1.6 times an outside diameter D1 of the lower steel pipe 2. An outside diameter D3 of the blade 10 is set to about 1.4 to 2.1 times the outside diameter D1 of the lower steel pipe 2 to improve balance in load resistant performance. The outside diameter D2 of the upper steel pipe 3 is set not more than the outside diameter D3 of the blade 10 to reduce driving torque for screwing in/intruding a steel pipe pile 1 to smoothly intrude the head part expanded screwing-in type steel pipe pile 1. Thus, bending stress intensity and horizontal displacement quantity at earthquake time can be restrained in response to the large bending moment generated in the vicinity of a pile head part of the steel pipe pile 1.
