摘要： PROBLEM TO BE SOLVED: To efficiently embed a screwed type steel pipe pile with a blade having large bearing power. SOLUTION: A spiral blade 5 for screwing, having a broad width and a large diameter extending over the inside and outside of a steel pipe 1, is fixed at the lower end of the steel pipe 1, and a leading cylinder 7 is fixed onto the inner circumference of the spiral blade 5 and provided droopingly. When the steel pipe pile A is embedded at this time, an auger in which a screw having a small diameter is installed to a lower section is inserted into the steel pipe pile A, disposed upright on a ground, and the steel pipe pile A is rotational- pressed in, excavating the ground by the screw.

摘要： PROBLEM TO BE SOLVED: To lessen the insertion resistance of a steel pipe pile by fixing a spiral wing over substantially one winding on the lower end of a steel pipe making the body of the pile, hanging a leading cylinder fixed on the inner periphery of the spiral wing and projected downward thereof, and projecting a plurailty of window holes and excavation plates on the peripheral wall of the leading cylinder. SOLUTION: When the steel pipe pile is pushed into ground while rotating it, the excavation plate 9 of the leading cylinder 7 excavates the ground. A part of soil and sand is made into flow to the leading cylinder 7 from the window hole 8, and the other part of soil and sand is moved to the lower face of an inner wing part 5b along the conical face of the leading cylinder 7. Next, the spiral wing 5 is cut into the outside ground of the leading cylinder 7, and screwed by the reaction force of the ground acting on the upper face of the spiral wing 5 to promote insertion. Soil and sand entering a gap 6b is consolidated on the peripheral ground while sliding on the upper face of the wing of spiral inclination. Lower side soil and sand and soil and sand excavated by the excavation plate 9 are made to flow in to be pumped into the steel pipe 1. Thus, the pile can be inserted and promoted only by rotating it by slight push pressure force, and can be buried without removing soil.

摘要： PURPOSE:To eliminate exposed parts of steel sheet piles on the ground to improve a scenic view, by covering the exposed parts of steel sheet pile driven in the ground with concrete or the like. CONSTITUTION:The upper ends of steel sheet piles 1 driven side by side are adjusted to be at the same level and the middle of horizontal part 3 of a number of reversely L-shaped plates 2 is placed on the upper end thereof and further, several bolts 6 are suspended at the rear of horizontal part 3. The lower part of bolts 6 are buried in concrete 7 filled at the upper rearpart of the steel sheet pile 1 and 10 the lower side of horizontal part. And a stuffing filler 9 is charged in the clearance between the vertical part 4 of the reversely L-shaped plate 2 and the upper front face of the steel sheet pile 1.

摘要： PURPOSE:To manufacture a double steel tube high in flexible rigidity by a simple means. CONSTITUTION:A band steel sheet having a hollow rectangular cross-section is spirally wound by spiral steel tube manufacturing devices 8, 9 and 10 and the end edges 1a and 1a are welded 13 and 14 by an inner welding torch 11 and outer welding torch 12. Thus, the double spiral steel tube A is manufactured. An arbitrary modulus of section of the double steel tube is freely obtained by adjusting the clearance between pinching rollers 6 and 6 when the band steel sheet is traveling.

摘要： PROBLEM TO BE SOLVED: To lessen the insertion resistance of a steel pipe pile by fixing a spiral wing over substnaitally one winding on the lower end of the steel pipe making the body of the pile, fixing it on the inner periphery to overlap a leading cylinder projected downward, and providing a small diameter spiral wing over substantially one winding on the lower end of the leading cylinder. SOLUTION: A steel pipe is pushed into ground while rotating it, an inner diameter spiral wing 8a is cut into the ground, and soil and sand are made to flow from a through hole 9 and a gap 10 into the leading cylinder 7 to be pumped upward. Next, the spiral wing 5 is cut into the outside ground of the leading cylinder 7, screwed by the reaction force of the ground acting on the upper face of the spiral wing 5, and insertion is promoted. Soil and sand entering the gap 6a of the outer wing part 5a of the spiral wing 5 is consolidated while sliding the wing upper face of a spiral inclination. The soil and sand entering the gap 6b of the inner wing part 5b is made to flow into the steel pipe, merged with the soil and sand made to flow in from the lower end of the leading cylinder 7 to be pumped upward. Thus, the insertion of the pile can be promoted only by rotating the pile by slight push pressure, and burying can be performed without removing soil.
