摘要： PURPOSE:To reinforce the bearing force at the front end without use of a compaction pile. CONSTITUTION:After a concrete body has generated its strength, a compactor 4 having the size and shape equivalent to a compaction pile is inserted in a hide pipe 2 by an intrusion rod 8 to insert to a required depth in the bearing ground to form a hollow 6. The compactor 4 is raised and cement milk is charged into at least the hollow 6. A compacted pile 9 having almost the same shape with the hollow 6 and the sufficient compressive strength to prevent the peripheral ground of the follow from loosening, is inserted in the guide pipe 2 and buried in the position of the hollow 6. While raising the intrusion rod 8, cement milk is charged in the guide pipe 2. Accordingly, a high yield strength cast-in-place concrete pile or the like can be driven by burying an inexpensive compacted pile and the construction cost can be reduced. And the compacting effect at the ground of the front can be securely obtained.

摘要： PURPOSE:To withdraw a guide pipe simply and quickly to reuse by placing the guide pipe for penetration of a compaction pile into an excavated hole for a cast-in-place concrete pile, etc., and applying a slipping agent to the peripheral surface of the guide pipe. CONSTITUTION:Excavation is made up to the front ground 7 to form an excavated hole 1, and a guide pipe 2 for penetration of a compaction pile 6 is placed into the excavated hole 1. At that time, a slipping agent reducing adhesion with a placed concrete 5 is applied to the peripheral surface of the guide pipe 2, and the peripheral surface of the guide pipe 2 is isolated from the concrete 5. The guide pipe is pulled out after required strength of the placed concrete 5 is exhibited. According to the constitution, the guide pipe is simply and quickly withdrawn to reuse, and a construction cost can be greatly reduced.

摘要： PURPOSE:To prevent muddy water or the like from erupting while a compaction pile is driven in by a method wherein the front end of a guide pipe is shielded watertightly with a covering material equipped with a plurality of cut grooves, and a plurality of such guide pipes are integrally attached to a reinforcing bar basket to be used for construction of a continuous underground wall. CONSTITUTION:A guide pipe 1 is constructed in such structure that the front end thereof is shielded watertightly with a cover 12. A number of cut grooves 15 are formed on the cover 12 so that the grooves extend radially from the center of the cover, and thereby breaking of the cover by driving-in of a compaction pile 2 is made easy. A reinforcing material in upside-down conical shape in 45 deg. inclination is provided to the inside of the guide pipe for making correction to centering of the compaction pile 2 easy. Then a specified number of guide pipes 1 are integrally attached to appropriate positions of a reinforcing bar basket 4 for cast-in-place concrete 3, and are inserted together with the reinforcing bar basket 4 into an excavated hole. Thereby the compaction piles 2 can be driven correctly into point ground and water accompanying excavation and underground water erupting around the compaction piles can be prevented from flowing backward.

摘要： PURPOSE:To attempt increase of compaction and a bearing power of the top edge ground of a structure of an embedded pile using a cast-in-place pile, a conventional concrete pile and others or a structure such as an underground continuous wall. CONSTITUTION:A compaction pile of a placing or a push-in type has a length L which is roughly same as the top end diameter of a cast-in-place concrete pile and others, and a diameter d2 of the top end part is about 5-30cm, a diameter of the upper end d1 is about 10-60cm, and it is formed in a convergent tapered shape of about l/5-1/20 as a whole. The compaction pile of a rotary press fitting type is based on this dimensional specification, and a plural number of top end cutters 3 are installed on the top end part of the pile, and side cutters 4 the maximum diameter d3 of the addendum of which is smaller than the upper end part diameter d1 are provided on a plural number of points on the outer peripheral surface of a tapered part 1. Additionally, a spiral projected line 5 is provided in the range which does not exceed 1/2 of the overall length L of the tapered part 1 above the top end part of the pile. Accordingly, as there is no harmful discharge of soil at the time of intrusion, a remarkable force is displayed for increase of a bearing power.

摘要： PURPOSE:To drive a high proof stress cast-in-place concrete pile or the like having increased a bottom support force when constituting cast-in-place concrete pile, embedded pile, and continuous underground base. CONSTITUTION:The work consists of three stages; a state in which a guide pipe 4 with its end opening closed with a lid plate 7 capable of being knocked out is made to reach the bottom ground 5 in approximately upright attitude before driving a main body 11, a stage in which a tightening pipe 6 is dropped after the completion of the main body 11 from above the ground to knock out the lid plate 7 and drive the pile 6 down to a required depth, and then a stage in which the guide pipe 4 is filledwith mortar column 1 to fix the tightening pile 6. The time required for driving the tightening pile 6 is very short and the work is made with a high efficiency. The work can be made easily by any person without much skill. A high proof stress cast-in-place concrete pile is provided with a great tightening hardening of the bottom ground and a great bottom supporting force by means of the tightening pile 6.

摘要： PURPOSE:To increase the horizontal resistance of a buried pile in a pile foundation. CONSTITUTION:A poor subsoil is improved extending over a horizontal range B1 in the extent of several times as large as a pile diameter B2 and a depth range L1 in the extent from several times to several dozen times as large as the horizontal range in peripheral grounds near the pile heads of buried piles 1 driven to the poor subsoil, and the horizontal resistance of the piles is increased by ground improved sections. Accordingly, the grounds near the pile heads are improved in spite of the minimum pile diameter B2 corresponding to vertical bearing power, thus suppressing the cost increase without augmenting the pile diameter and the number of the piles, then elevating the horizontal resistance of the piles.

摘要： PURPOSE:To reinforce the supporting force through the compaction of the foundation ground. CONSTITUTION:Concrete is placed in a direct foundation part 4 with through holes 3 for constructing compaction piles 2 on the excavated foundation ground 1. After the manifestation of strength of the placed concrete in the direct foundation part 4, the compaction piles 2 are passed into the foundation ground 1 using the through holes 3. After the penetration of the compaction pile 2, concrete 5 or the like is filled in the through holes 3 to fix the compaction piles 2, and a structure 7 is completed on the direct foundation part 4. The quaggy foundation ground 1 is thereby compacted easily and positively to reinforce the supporting force, and the sinking of the structure can be suppressed to a minimum so as to contribute largely to the improvement of safety and to the construction of the reliable structure.

摘要： PURPOSE:To ensure that a compaction effect is exhibited without adversely affecting the penetrating state of a compaction pile at all by promptly and surely collecting a penetration rod without easing its penetrating state. CONSTITUTION:A back face portion 3a, as determined in relation to the direction of rotation of a male hook portion constituting a bayonet mechanism at the end of a penetration rod 1, is formed into an inclined face with a gradient theta suitable for rotational pushing and extraction. The side portion 4a of a female claw portion 4 constituting a bayonet mechanism at the end of a compaction pile is formed into an inclined face with roughly the same gradient theta as the gradient theta of the back face portion 3a, and the compaction pile 2 is forced to reach end ground with the hook portion 3 of the end of the penetration rod locked to the claw portion 4 of the compaction pile. After the pile 2 has reached the end ground, the compaction pile is driven into the end ground while the penetration rod is rotated in the direction in which the back face portion 3a of the penetration rod abuts to the side face portion 4a of the claw portion 4 of the compaction pile. Even after being driven to a predetermined depth, the penetration rod is rotated and pulled upward and is thereby separated from the compaction pile.
