摘要： PURPOSE:To reduce noise pollution by manufacturing a concrete sheet pile in which feeding passages of the high pressure water and the compressed air are provided, and respectively feeding the high pressure water and the compressed air from the upper end, and jetting out them from the lower end, and pressing the sheet pile in the ground with a press-in machine. CONSTITUTION:A high pressure water feeding passage 2 and a compressed air feeding passage 2' are provided in a concrete sheet pile main frame from the upper end to the lower end to enable the filling from upper end openings 3, 3' of these passages and jetting out from lower end openings 4, 4' respectively. Chucking of a press-in machine positioned near the press-in position and the concrete sheet pile are performed, and the ground of the lower end surface is drilled by jet of the high pressure water, and cut pieces mixed in the water are pulled up to the upper along a side wall of the sheet pile by the compressed air, and while the concrete sheet pile is pressed-in the ground deep by the press-in machine. Sheet pile press-in work with low noise pollution, high perfor mance, and high efficiency can thus be performed.

摘要： PURPOSE:To secure the safety of the ground by providing high pressure water supply lines and compressed air supply lines lengthwise to the insides of concrete sheet pile bodies and pouring respectively high pressure water and compressed air from openings of their upper ends to make it possible to spout them from openings of their lower ends. CONSTITUTION:A prestressed concrete (PC) sheet pile A is manufactured as stretcher shaped sheet pile bodies 1 having a U-shaped section and overall length of about 20m of the PC. High pressure water supply lines 2, 2 and compressed air supply lines 2', 2' are provided to the insides of right and left sides of the sheet pile bodies 1 respectively lengthwise extending from the upper ends to the lower ends, and the high pressure water and compressed air are poured from openings 3, 3' of the upper ends of each supply lines 2, 2' to make it possible to spout openings 4, 4' of the lower ends. Cutting pieces are pushed down along a side wall by the compressed air while cutting the ground of the lower ends of the sheet pile bodies 1 by high pressure water force, and they are pushed deeply into the ground. According to the constitution, they can be inserted with a low noise, high efficiency and high ability.

摘要： PURPOSE:To reduce noise when a pile is driven as well as raise the efficiency of driving operation by a method in which a concrete sheet pile having a water- conveyance hole from upper end to the lower end is driven into the ground while jetting high-pressure water by means of a vibration-type pile driver. CONSTITUTION:A prestressed concrete sheet pile A of a nearly U-shaped cross section is driven into the ground by means of a vibration-type pile driver. In this case, high-pressure water is supplied to water-conveyance holes 2 and 2' formed from upper end openings 3 and 3' to lower end openings 4 and 4' of both sides of the pile 1 and jetted from the openings 4 and 4'. The flow rate and pressure of the high-pressure water and the driving force of the vibration- type pile driver are regulated according to the characteristics of the ground layer. Grout is also injected into the lower end portion of the sheet pile A by using the holes 2 and 2' for foot protection.

摘要： PURPOSE:To bury a concrete sheet pile deeply in the ground and, at the same time, to make it possible to execute the consolidation of foundation of the lower end of the concrete sheet pile. CONSTITUTION:A sheet pile main body 1 having the approximately U-shaped section is constituted of a flat plate-like sheet pile base 1e extended in the vertical direction and sheet pile projections 1f and 1f projected to both ends of the sheet pile base 1e and is molded of concrete. Water-conveyance holes 2 and 2' extended to the vertical direction are provided in the sheet pile projections 1f and 1f, at the same time, upper end openings 3 and 3' of water- conveyance holes 2 and 2' are projected into a recessed space S formed of the sheet pile base 1e and sheet pile projections 1f and 1f, high pressure water or grout is fed from the upper end openings 3 and 3', and such water-conveyance holes are obtained as high pressure water or grout can be injected directly downward.
