摘要： PURPOSE:To construct a high yield-strength cast-in-place concrete pile having large end bearing force by forming a projection to be rotated to the upper section of the inner circumferential surface of a pile body, mounting a side face cutter and a spiral projection to the lower section of an outer circumference and installing an end cutter at a front end section protruded while penetrating the pile body. CONSTITUTION:When a compaction pile is intruded to an end ground and compacted, a connector 3 is inserted into the hollow section 5 of a pile body 1 from an upper section, and the pile body 1 is turned slightly under the state, in which the constricted sections 10 of the connector 3 are fast stuck onto the inner circumferential surface of the lower end section of the hollow section 5. Consequently, the hanging sections 9 of the connector 3 creep to the lower ends 7a of the projections 7 to be rotated of the compaction pile 1 and are brought to a caught state, and the pile body 1 is borne under a hung state. An intrusion rod is operated under such a state, and the pile body 1 is intruded into the end ground in a glass pipe in an excavated pit. When the pile body 1 is penetrated completely, the pulling-up operation of the intrusion rod is conducted while the inside of the end ground is impregnated with cement milk from a discharge opening 7 through the impregnating hole of the intrusion rod.

摘要： PURPOSE:To increase the forward end supporting force so as to exhibit a compaction effect in the ground by forming a saw-toothed step part on the outer periphery of the upper part of a compaction pile, and intruding the compaction pile in the hole bottom ground until it is intruded into the hole bottom ground. CONSTITUTION:Conical saw-toothed step parts 1a tapered downward are formed in plural stages on the outer periphery of the upper part of a compaction pile 1. Plural annular check valves 3 having through holes in their centers are installed on the inner surface of the lower end part of a guide pipe 2. While the check valves 3 are curved downward and deformed, the compaction pile is inserted in the through holes and passed therethrough. The compaction pile 1 is intruded into the hole bottom ground 4. The inside diameter part of the nonreturn valve is locked in the saw-toothed step part 1a. Thus, the compaction pile which is once intruded in the hole bottom ground 4 is mechanically fixed, so that the forward end supporting force is increased to exhibit a compaction effect in the hole bottom ground 4.

摘要： PURPOSE:To obtain a guide pipe used to intrude a compaction pile to increase a top end holding power into the top end ground (hole bottom ground) in a structure of a buried pile and others using a cast-in-place concrete pile, a continuous underground Wall or a conventional concrete pile. CONSTITUTION:A soil overturning plate 10 to shield the top end opening part of a guide pipe 4 which consists of a steel pipe having its inside diameter slightly larger than the outside diameter of a compaction pile 6 and having its length more than the same of the depth of a pile hole and others is installed. This soil overturning plate 10 is provided with a through hole 11 of the roughly same diameter as the top end diameter of the compaction pile 6 on its central part, and a plural number of cut grooves 9 are formed and arranged radially from the central part. The soil overturning plate 10 is constituted free to break along the cut grooves 9 by the compaction pile 6. Consequently, it is possible to work easily and well in workability without being interrupted by drilling mud in the hole in building work of the guide pipe or a conventional pile. It is possible to prevent soil discharged at the time of intrusion of the compaction pile 6 from intruding into the guide pipe and the conventional pile.
