摘要： PROBLEM TO BE SOLVED: To make fastening tight and correct by a method wherein a plurality of chuck pieces to be held to holding notches provided at intervals in the longitudinal direction of splines of an excavating shaft are detachably provided at a rotative cylindrical holder supported with a rotative driving device. SOLUTION: While an excavating/agitating shaft is rotated with chuck pieces 27 held with holding notches 24 of splines, the weight of a lower carrier and a lower rotative driving device 10 is applied as excavation load through a holder 25 to an external shaft 12 rotatively driven by the chuck pieces 27. As the chuck pieces 27 are held with the holding notches 24, the external shaft 12 can be prevented from slipping in the axial direction. As the driving device 10 descends to the lowest position, a cam-lifting oil-hydraulic cylinder 39 is driven, and the chuck pieces 27 are thereby separated from the holding notches 24 while the driving device 10 is lifted through the lower carrier. Then, the chuck pieces 27 are held with the upper holding notches 24, and excavation is made again with excavation load applied, and the excavating shaft can be held certainly while excavation load and thrust force are applied certainly.

摘要： PROBLEM TO BE SOLVED: To contrive to reduce both size and weight by mounting a cylinder which moves an operation cylinder vertically on a cylinder which is designed to rise freely in a non-rotary state, on a support material and pressing a lock claw lever with the vertical movement, thereby engaging the lever with or disengaging the lever from a locked projection. SOLUTION: In the case when an outside shaft 11 is separated, an operation cylinder 29 is adapted to rise with a hydraulic cylinder 31 connected to a non-rotary holder 4. When a passive projection 27 is pushed up against the force of a spring 24 with an operation ring 30, the tip of a toe 21 of each claw lever 20 is disengaged from a locked projection 26, thereby canceling the locked state water a male joint 18 is pulled from a female joint 14, thereby separating an outside shaft 11. In the case when a new outside shaft is connected to the female joint 14, the male joint 18 of the outside shaft 11 is fitted in the female joint 14, thereby lowering the operation cylinder 29 with the hydraulic cylinder 31. When the operation ring 30 is separated from the passive projection 27, the claw lever 20 is rocked by the spring 24 so that the tip of the claw tip 21 may be locked with the locked projection 26, thereby locking the outside shaft 11.

摘要： PROBLEM TO BE SOLVED: To contrive to reduce unsteady load applied on a mast by providing a spare rod rack on the lower part of the mast and pivoting a holder turnably on the upper part of the mast and moving freely forward and backward a movable rod which hangs a rod hanger. SOLUTION: A spare rod rack 16 is provided on the side surface of the lower part of a mast 2 while a holder is turnably pivoted on the upper part of the mast 2. When an excavation and agitation rod 11 is diggingly advanced for one rod, an outside rod 12 and an inside rod 12a are separated from each other, thereby lifting up the whole upper carrier 4. The forward and backward moving track of a mobile rod 23 slidingly held on the holder 22 is set on the central line of a spare rod rack case 19, thereby hanging up and transferring the rod to a rod addition position with the mobile rod 23. After the positional adjustment is over, the lower end of the spare rod 11 is connected to the preceding excavation and agitation rod 11, thereby connecting the upper end to an output shaft of an upper part rotary drive device 9.

摘要： PROBLEM TO BE SOLVED: To prevent a drive device from falling down even when a wire is cut by advancing a holding arm preliminarily so that it may come in contact with a drop inhibition block when executing rod adding work in a state in which a drive device is supported with the wire. SOLUTION: After almost the whole length of an excavation and agitation rod 7 has been diggingly advanced underground, a drive device 4 is separated from the agitation rod 7, thereby lifting up the drive device 4 to the uppermost higher position of a mast 2 by winding up a wire 6. Then, a movement drive hydraulic cylinder of a drop preventive device A is driven, thereby advancing a holding arm 15 to a lift preventive position. After a drop preventive inhibition block 18 comes into contact with the holding arm 15, the wire 6 is slightly loosened. In this state, a new rod is connected between the drive device 4 and the preceding agitation rod 7. During this work, since the wire 6 is loosened, there is no danger that the wire 6 is cut down. Even if the wire 6 is rewound by an operational failure, the drive device is supported on the holding arm 15, which makes it possible to protect the drive device 4 from falling down.

摘要： PROBLEM TO BE SOLVED: To prevent the entangling of wires by winding up a weight with a bit in an excavating casing, dropping it by the tare weight for an excavation, and making the weight and the wires independently rotatable around the axis via a swivel joint. SOLUTION: An excavating casing 4 is rotated by the hydraulic cylinder of a driving device and pressed into the ground. The winding up of wires 12 by a winch and the release of a clutch are conducted in turn, and the ground is excavated via the ascent and drop of a weight 11. When the excavating casing 4 is rotated, the sediment in the casing 4 is rotated together with the casing 4, and the weight 11 is also rotated together. A swivel joint 31 is inserted between the weight 11 and the wires 12 not to convey the rotation of the weight 11 to the wires 12, and the entangling of the wires 12 is prevented.

摘要： PROBLEM TO BE SOLVED: To construct a diaphragm wall and excavate the inside of a cylinder simulta neously and construct a durable extremely large and deep shaft at a low cost and in a short time. SOLUTION: An excavating machine body 4 is inserted in a guide column 3 vertically erected in the ground and hung by a crane to freely move up and down to make it possible to adjust the vertical pressure and excavate the ground while reversely turning peripheral rotary arms and an excavating rotary cutter 6 at the front end at about 180 degrees. The peripheral rotary arm is further provided with circumferential tractive bits 7 to control the circumferential transfer speed. The guide column 3 can be omitted. In this case, a sheave for underground is fitted to the center of excavating machine to sound the position of a buoy on the ground and adjust an excavating machine guide plate for the control of the excavating accuracy. In this way, reinforced concrete is placed in a stable liquid 8 in the shaft to form a cylindrical impervious wall 10. And further, a preventive member 11 against falling is pressed on the shaft wall and the second stage is excavated bellow the first stage shaft and the impervious wall 12 is formed in the same way. These processes are repeated to construct an extremely large and deep shaft.

摘要： PROBLEM TO BE SOLVED: To miniaturize an equipment while easily acquiring data at several places continuously or at every fixed place. SOLUTION: In this method, a sensor is charged into a ground excavation pit 20 from the outside, and information in the excavation pit 20 is obtained. A probe 30 having at least the sensor and a memory, in which information detected by the sensor is stored, is charged into the excavation pit 20 from the outside, and information detected by the sensor at a specified place is stored in the memory. The probe 30 is recovered to the outside from the inside of the excavation pit 20, and excavation information at every place is acquired by reading stored information in the memory on the outside of the excavation pit 20 while collating depth data recorded on the ground and data from another ground timer.

摘要： PURPOSE:To effectively remove slime, by arranging an injection pipe at one side of outer sides of a reinforcement cage of a prior element and oppositely arranging a suction pipe for the injected slurry of the injection pipe at the other side. CONSTITUTION:A slurry infection pipe A is arranged at one of the outer sides of a reinforcement cafe 4 erected in a prior element B Next, a suction pump 5 is connected to the other side and a suction pipe C provided with a reverse pipe 6 at the front end thereof is arranged. At that time, the front injection nozzle of the slurry injection pipe A is positioned to face the reverse pipe 6. The slurry is sucked by the suction pipe C through the reverse pipe 6 while injecting the slurry from the injection nozzle 2 and the slime on the groove bottom is sucked gradually with the slurry stream. In this way, slime can be removed even in the treatment from the outside of the reinforcement cage 4.
