摘要： PURPOSE:To obtain a pile having high yield strength against bending moment by setting a spiral or annular horizontal restraint bar between the periphery of a vertical reinforcing bar group and the periphery of a pile. CONSTITUTION:PC steels 2 are set in the longitudinal direction of a pile to form a vertical reinforcing bar group, aud a spiral or annular horizontal restaint bar 3 is set between the periphery of the vertical reinforcing bar group and the periphery of the pile. A prestressed concrete pile 1 is formed by centrifugal forming in such a way as to bury the reinforcing bar group. The pile 1 having high strength against bending moment can thus be obtained.

摘要： PURPOSE:To obtain the arch culvert of even density or the like, by placing concrete at the both side sections and the arch section, after concrete is placed at the bottom section of a mold for the arch culvert, via an internal frame for the bottom section which is freely opened and closed. CONSTITUTION:An internal frame 7 for the bottom section of a mold 4 for an arch culvert is freely opened and closed in the direction A, and an external frame 14 for the arch section is freely opened and closed in the direction B. To produce the arch culvert, first the internal frame 7 is opened and concrete 30 is placed at the bottom section, and the compaction and formation are carried out by vibration. Then, after the external frame 14 is opened and concrete 18 is placed at the both side sections and compacted, an external frame 17 at the top section is fitted and concrete is cast at the arch section through the injection slot 16. By this method, the concrete can be smoothly flowed in, and the arch culvert of even density or the like can be obtained.

摘要： PURPOSE:To prevent a foreign matter from interposing into an inner circumferential surface by eliminating wavy unevenness of the surface by a method wherein concrete is placed within a concrete form by setting a leverlike body to an arrangement position of a reinforcing steel material and the leverlike body is pulled out under a state where the concrete is not solidified. CONSTITUTION:A leverlike body 2 as a concrete form for molding of a sheath part for piercing through a main line of a pillar constituted of a steel pipe possessing a form corresponding to a section of the same sheath is set up to the sheath part in the concrete form 1 for manufacture of a precast concrete pillar member. Then after arrangement of necessary reinforcing iron rods such as reinforcing hoop iron rods have been performed, concrete 4 is placed within the concrete frame 1, the leverlike body 2 is pulled out under a state where the same placed concrete 4 is not solidified and the sheath part is molded. Accuracy of the sheath part can be secured without performing a displacement or a deformation through external force at the time of placement of the concrete, by constituting the leverlike body of a member possessing sufficient strength.

摘要： PURPOSE:To curtail the cost of an excavator by a method in which a rotary shaft is thrust and projected from a supporting frame, a second supporting arm is pivotally attached to both ends of a first supporting arm pivotally attached to the rotary shaft, and a bit to be driven by the rotary shaft is attached to the outer end of the arm. CONSTITUTION:A center bit 14 is attached to the lower end of a drill pipe 3 set in a well 2, and a first supporting arm 5 is pivotally attached to the upper part of the pipe 3. A second supporting arms 8 and 9 are pivotally attached to both ends of the arm 5 in a bendable manner, and outer ring bits 12 and 13 are attached to the end of the arm 5. At he beginning of excavation, the arms 5, 8, and 9 are bent and the bits 12 and 13 are contacted with the inner wall of the well 2 to excavate the inside ground of the well 2 in conjunction with the center bit 4. When the bits 12 and 13 reach the cutting edge of the well 2, the second arms 8 and 9 are opened, the excavating radius of the bits 12 and 13 is increased, thereby excavating the ground below the cutting edge of the well 2.

摘要： PURPOSE:To improve a resistance force against the pull-out force, lateral slipping, and negative friction of a pile, by burying an anchor member fixed at the lower end of the pile, into a bulb due to cement milk. CONSTITUTION:A pile 1 is erected, and ground is excavated by a spiral auger 4, and at the same time, the pile 1 is sunken and set. After the pile 1 is sunken and set to a specified depth, ground is excavated to an given depth by the spiral auger 4, and then the spiral auger 4 is hoisted and at the same time, cement milk is jetted under varied pressure from the auger 4. By this method, excavated sediment in ground is mixed with cement milk to form a bulb 5 for the consolidation of the foundation at the lower end of the pile 1. Besides, an anchor member 2 fixed at the lower end of the pile is buried in the bulb 5, and by solidifying the bulb 5, a resistance force against the pull-out force, lateral slipping, and negative friction of the pile 1 can be improved.

摘要： PURPOSE:To perform rapid sinking and installation of a well caisson, by a method wherein the well caisson is secured to a second support beam, the second beam is engaged with the upper surface of a first support beam to support the well caisson, and the second support beam is disposed to the under surface of the first support beam to press in the well caisson. CONSTITUTION:The upper end of a well caisson W is secured to the undersurface of a second support beam 10, the second support beam 10 is engaged with the upper surface of the first support beam 7, and this causes supporting of the well caisson W to a support frame 1. After, with this, a ground in the vicinity of the lower end of the well caisson W is excavated down to a given depth, the second support beam 10 is removed from the well caisson W. After the first support beam 7 is raised by means of a hydraulic jack 8, the second support beam 10 is secured to the well caisson W again, and the first support beam 7 is lowered with the aid of the hydraulic jack 8 to press the well caisson W into a ground. This enables to perform supporting and pressing-in of the well caisson W only through engagement of the second support beam with the first support beam, and permits rapid sinking and installation of the well caisson W.
