Field of the Invention The present invention relates to a foundation construction machine such as a ground suspension water wall construction machine or a ground improvement machine, a boring machine, etc., for connecting a plurality of shafts and penetrating them into the ground. Of the device.

継ぎ足されながら地中へ貫入される。2. Description of the Related Art Generally, a long shaft is often used in a foundation construction machine as described above. For example,
In the ground agitation type ground improvement device, agitation shafts of several tens of meters are installed vertically. Since such a long shaft is extremely difficult to manufacture and transport as it is, it is generally divided into a plurality of parts in the axial direction and appropriately inserted at the construction site to penetrate into the ground.

送及び貫入を一度に行うことができる利点がある。Therefore, in recent years, various devices have been proposed for automatically connecting shafts and penetrating them. For example, in Japanese Unexamined Patent Publication No. 2-243817, while stirring the stirring shaft stored in the stirring shaft holding device portion by the stirring shaft gripping mechanism portion, the stirring shaft portion is swung to move the stirring shaft to the front surface of the guide frame, and sequentially. It is shown to be replenished and supplied to a fixed position. In addition, Japanese Patent Publication No. 3-441
In Japanese Patent Publication No. 98, a joint holder provided at the tip of an arm grips two shafts stored in a storage position at a time, and then these shafts are moved from the storage position as the arm rotates. It is shown that it is moved horizontally to the penetration position at the same time. This device has the advantage that the two shafts can be transferred and penetrated at the same time.

複雑化は避けられず、その分、装置の重量及びコストは
増大する。In each of the devices disclosed in the above publications, the shaft is gripped by the tip of the turning member such as an arm, and the turning of the turning member causes the shaft to move from its storage position to the shaft of the shaft penetrating means. Since it is to be handed to the gripping part, the shaft is gripped from the side by the agitation shaft gripping mechanism part, the additional holder and the like. Therefore, when the outer diameter of the shaft is large, it is necessary to increase the size of the attachment holder and the like in accordance with this, and when the shape of the shaft is complicated,
For example, when the shaft is an excavating shaft having a screw over the entire circumference and the entire length, it is necessary to design in consideration of avoiding interference with the holder by joining the screw and the like. In these cases, the size of the joint holder is increased,
Complexity is unavoidable, and the weight and cost of the device increase accordingly.

Connecting the upper end to the penetrating device,
It is necessary to separate the shaft and the joint holder, and to connect and disconnect the shaft and other members many times from the time when the shaft is taken out to the time when the shaft is inserted.

の安定性にも問題が生じる。Further, in order to improve the efficiency of the shaft penetrating work, it is preferable that a large number of shafts can be penetrated at the same time. However, in the above-mentioned conventional apparatus, a large number of shafts are supplied to the shaft penetrating means at once. The strength of the swiveling member must be increased until the weight of these shafts can be withstood, and the weight increase due to the reinforcement is inevitable. In addition, there is a problem in the stability of the device when the shaft is conveyed.

It is an object of the present invention to provide a shaft penetrating device capable of performing the above-mentioned operation, and more preferably to provide a shaft penetrating device suitable for simultaneously adding and penetrating a plurality of shafts.

The shaft driving device 92 and the respective excavating shafts 6 held by the shaft driving device 92 are set at predetermined penetration positions. In this state, by operating the excavation drive motor to rotate each excavation shaft 6 around its own axis and operating the winch in the pulling down direction, the five excavation shafts 6 are arranged in the mutually penetrating arrangement direction. And it can penetrate underground at the same time. Then, by stopping the excavation drive motor and the winch in a state in which most of the excavation shafts 6 have entered the ground 10, that is, a state in which only the upper portion of each excavation shaft 6 projects from the ground 10, The penetration operation of the excavation shaft 6 in the row is ended.

供給位置に供給することができる。During the pulling operation of the shaft driving device 92, the excavation shafts 6 are fed by the first transfer means 50 and the second transfer means 70 on a row basis on the side of the shaft storage means 14. That is, by operating the transfer motor, the rear sprocket 62 is rotated in the direction of the arrow in FIG. 8 to drive the chain 64. By this drive, each carriage 54 connected to the chain 64 travels on the guide rail 53. Then, when the carriages 54 move by one pitch in the line, the driving by the transfer motor is stopped. As a result, the excavation shaft 6 in the second row from the front can be transferred to the front row. Therefore, by contracting the hydraulic cylinder 15 again from this state and advancing the shaft accommodating means 14, the excavation shafts 6 newly fed to the front row can be respectively supplied to the shaft supply positions.

る。After the above-mentioned supply, the turntable 82 and the entire penetrating / pulling-out means 18 are again rotated 90 ° counterclockwise in FIG. 7 to move the shaft driving device 92 from the penetrating position to the shaft supplying position. Then, as in the first penetration operation, each excavation shaft 6 is held by the shaft joint 96 of the shaft drive device 92, the shaft drive device 92 is pulled up to the upper limit position by the operation of the winch, and the hydraulic cylinder 15 is extended. After retracting the shaft accommodating means 14 by rotating the turntable 82 and the penetrating / extracting means 18 in the clockwise direction in FIG. 7, the excavating shafts 6 held by the shaft driving device 92 are already moved. It can be located above each excavation shaft 6 that has penetrated the ground 10 at the penetration position.

Until then, the shaft drive device 92 is lowered, and the shaft attaching / detaching device 20 is operated from this state, so that the upper end of the already penetrated excavation shaft 6 and the lower end of the excavation shaft 6 supplied this time are connected. Thereafter, the winch is further operated in the unwinding direction, and the excavation drive motor is operated to add and penetrate the excavation shaft 6 in the same manner as the excavation shaft 6 in the first row. Hereinafter, by repeatedly performing such an operation, the excavation shaft 6
It is possible to proceed with the penetration while successively adding up.

Therefore, once the relative positions of the shaft housing means 14 and the penetrating and extracting means 18 are determined, the shaft driving device 92 can be simply rotated thereafter.
Can be automatically and accurately positioned at the penetration position and the shaft supply position. Moreover, since the excavation shaft 6 can be fed by the first transfer means 50 while the excavation shaft 6 is being penetrated, the efficiency is good and the working time can be shortened. Further, since all the excavation shafts 6 are stored in the upright state, the storage space thereof is small, and even if the shaft length of the excavation shafts 6 is increased in order to reduce the number of shaft additions, the storage space described above is reduced. Does not increase.

The space required to install the is reduced. In particular, when the number of times of addition (that is, the number of shaft groups) is large, there is a disadvantage that the linear transfer type shaft storage means 14 shown in the second embodiment has a large protrusion size in the storage arrangement direction.
According to the device shown in the third embodiment, the shaft storing means 110
There is an advantage that the installation space can be distributed in the turning direction of the shaft drive device 5. This effect becomes more remarkable when the number of shafts to be excavated at one time (the number of shafts in each shaft group; three in the illustrated example) is small.
