摘要： PROBLEM TO BE SOLVED: To surely pull out an existing pile when it is damaged, destroyed or ruptured. SOLUTION: This cylindrical casing for pulling out the existing pile has an excavating claw at a lower edge, and has an inside diameter larger than an outside diameter of the existing pile to be pulled out. In the casing, the plurality of claws are provided at regular spaces in a circumferential direction among them on a peripheral wall near a lower end of the casing. Each of the claws is journaled in such a manner as to be swingable between a position to be brought about almost along the peripheral wall of the casing by earth pressure in the casing during the normal rotation of the casing, and a position to be raised almost in a centripetal direction by the earth pressure in the casing during the reverse rotation of the casing. Additionally, each of the claws has a length which is set so that the claw in the position to be raised in the centripetal direction can be locked to a lower end of the existing pile when the casing is jacked into the outer periphery of the existing pile.

摘要： PURPOSE:To lessen an earth removing amount and to construct a bearing pile with one continuous stage of work by inserting an auger into a hollow hole of a pile to make the force-fit of the auger into the hole while making excavation, making excavation larger than an diameter of the pile when it reaches a bearing layer, and constructing a bulb while injecting a foot protection agent to penetrate the lower end of the pile into the bulb. CONSTITUTION:An auger 2 is inserted into a concrete pile 1, and an excavation device 3 is mounted to the lower end thereof and is settled into the ground 11. At that time, most part of excavated moving earth is consolidated in a hollow hole of the pile 1. After that, the lower end of the pile 1 is made to reach a bearing layer 12, and a diameter of a wing 4 is widened to excavate a forming section of a bulb 13. Cement milk is injected to construct the bulb 13. Then, the force-fit of the lower end of the pile 1 is made. According to the constitution, the pile having strong bearing force can be quickly executed with one continuous stage of work.

摘要： PROBLEM TO BE SOLVED: To provide a locking means in place of a conventional guide cutter to prevent an enlarging cutter from spreading radially. SOLUTION: The enlarging excavator is structured so as to make an excavation head 3 connected to the lower end of an excavation rod 2 and inserted into a pipe casing 1 that is forced out from the pipe casing by normal rotation and axial force fitting and the enlarging cutter 11 of the excavation head 3 spreads radially in the enlargement direction. In such case, it is structured by providing locking hardware 15 to prevent the enlarging cutter 11 from spreading in the excavation head 3 when the excavation head 3 is in the pipe casing 1, and by fixing a shear ring 16 to take out the locking hardware 15 from the excavation head 3 to the inside perimeter of the lower end of the pipe casing 1 when the excavation head 3 is pushed out from the lower end portion of the pipe casing 1.
