摘要： PURPOSE:To obtain a method of constructing a foundation by which a large supporting force can be obtained and a large and long pile can be constructed and industrial waste is reduced. CONSTITUTION:A front end shoe 2c having an excavating function is attached to the front end of an inside-excavating auger shaft 2 to excavate ground while going ahead of a pile 1. The excavated soil is discharged from the inside of a friction cutter 2b to the upper side by an air lift and the soil and sand in a pile chamber is conveyed to the upper side by an auger screw 2a. After the front end shoe 2c has reached a specified level of ground, the front end shoe 2c is struck by an air hammer equipped in the inside of the auger shaft to stiffen the front end ground 3. After a specified striking energy has been given, the front end shoe 2c is separated from the auger shaft 2. And the auger shaft is pulled up and the front end shoe 2c is solidified with the pile 1 as a unit by cement milk or the like.

摘要： PURPOSE:To increase the bearing force of a foot protection pile, by arranging rings, disks, spiral springs, materials increasing the shearing resistance, tension rods, etc., under the pile or providing protrusions or grooves on the outer periph eral face of the pile. CONSTITUTION:The ground is excavated and soil cement is charged in the excavated hole 1 and an existing pile 2 is inserted to fix in the bearing ground. On constructing this foot protection pile, materials 8 increasing the shearing resistance like rings 3 or disks 5 having a larger outer diameter than pile or steel rods, struts, cloths, etc., are arranged in advance in the soil cement under the inserted pile 2. Or a spiral spring 7 is wound at the lower end of pile 2 and the pile is inserted in the released state thereof. Or protrusions 2a, grooves 2b, tilting pile protrusions 2c, tension rods 9, etc., are provided at the outer periphery of the pile 2. In this way, it can withstand punch breaking or split breaking forces acting on the soil cement.

摘要： PURPOSE:To facilitate construction of a foundational pile by forming a cone buried on the plane of a hole excavated in the ground in a circular cone waveform, and giving a function capable of making force-fit of the cone easily into the hole thereto. CONSTITUTION:After a hole having a specific depth is excavated in the ground 12, a bucket 26 is suspended with a wire 27 to eliminate slime in muddy water after the elapse of specific time, and a conical cone 28 is placed to the bottom of the hole. The cone 28 is formed of a conical section 30, a screw section 32 and a leading projection 34 and, at the same time, an interlocking gutter interlocked with a shaft 20 of an excavator is provided to a conical flat surface. After that, screwing-in work of the cone 28 is such that the lower end of the shaft 20 is interlocked with the interlocking gutter of the flat surface of the cone 28, proper rotation and force-fit of the shaft 20 act on the excavator in such a state and that the cone 28 is rotated to screw it in the bottom of the hole so as to move no earth of the ground 12, and after that, reinforcing bars are arranged to the hole to place concrete.

摘要： PURPOSE:To widen an enlarging blade so that enlargement and excavation can be made by a pile end, confirm such a state from the ground and surely withdraw the enlarging blade to an original state. CONSTITUTION:An excavating blade 12 is provided to a cylindrical shaft 11, and both upper and lower bits 1a and 1b divided into two parts so as to cross an excavation bit 1 forming an excavating blade 13, a connection joint 6 inserted to the insides of cylinders of the upper bit and lower bit, a guide shaft 7 freely inserted into a slot 115 formed in the cylindrical shaft 11 of the lower bit and fixed to the connection joint 6, an enlarging blade 3 mounted to the lower bit 1b and a link mechanism 4' connecting the guide shaft 7 and the enlarging blade 3 are provided to the lower end of the excavating blade 12. When the upper bit 1a is forwarded, both upper and lower bits maintain the shape of the excavating blade in a state prior to the division, and while the link mechanism 4' stores forcedly the enlarging blade 3 in the excavating blade, when the upper bit 1a is reversed, the enlarging blade 3 is projected outward of the excavating blade 12, and the guide shaft 7 is interlocked with the other end of the slot 115 in order to maintain a projection state.

摘要： PROBLEM TO BE SOLVED: To establish a method to inspect whether a bearing pile, etc., constructed underground is in the sound condition, from over the ground surface while the positioning remains in the initial. SOLUTION: At least two metal members 3 for inspection are installed in such a way as elevating to over the ground surface from the head of a pile concerned, and after curing of the pile, a sensor 5 of an inspection system 4 is installed on the top of one of the metal members 3 protruding over the ground surface, while the top of the other metal member 3 is excited, and the vibratory propagation in the pile 1 and the situation of reflected waves are recorded and displayed by the inspection system 4. The obtained vibratory propagation and the situation of reflected waves are observed, and inspection and/or check is made if there is any damage in the pile 1 and the position if any.

摘要： PURPOSE:To inspect an existing pile itself and also inspect whether or not the consolidation of a foundation part which is stuck integratedly with the base edge part of the existing pile is sufficiently constructed quantitatively. CONSTITUTION:The head part of an existing pile 54 is struck by an striking body 2, and vibration from a pile body caused by striking is detected by the vibration detector 1 of the head part of the existing pile 54, and an electric signal corresponding to the vibration caused by a striking impulse is outputted by the vibration detector 1. The electric signal is memorized in a charge amplifier 3 and transmitted to a personal computer 5 through an A/D converter 4, and if a waveform 6 is displayed during vibration, the periods of time until the respective peaks of the reflection of the existing pile 54 and the reflection of a base bottom part are detected from the peak of the striking impulse can be measured based on the waveform 6. Therefore, the length of the foundation consolidation agent 52 which is integrated with the existing pile 54 itself and the base edge part of the existing pile 54 can be measured, thus it is possible to inspect the quality of piling work quantitatively.
