DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material stocking apparatus and a material transferring method, and more particularly to a material stocking apparatus and a material transferring method for stocking materials in a shaft in a shield method.

[0002]

BACKGROUND ART The role of a shaft in a conventional shield method is mainly to be used as a starting and reaching base of a shield excavator. It is used as a passage to carry various equipment such as segments, rails, sleepers, etc. into the tunnel.

[0003] Further, such equipment is generally temporarily placed in a plane in a stock yard provided on the ground of a shaft base, and is generally carried into a tunnel as required.
Under such circumstances, in order to reduce the space of the shaft shaft base, a tunnel shaft structure as disclosed in Japanese Patent No. 2524904 has been proposed.

In this tunnel shaft structure, a wall of an appropriate thickness made of concrete or the like is formed on the peripheral wall surface of the shaft, and a ring-shaped horizontal partition wall is formed on the inner peripheral surface of the wall at appropriate intervals in the vertical direction. The partition wall is formed as a storage room for materials for tunnel construction.

[0005] A stacker crane is arranged in the shaft, and the material transported by the bogie to the supply port at the upper end of the shaft is received by a fork member of the stacker crane, and the stacker crane is moved in the circumferential direction along the rail in the shaft. By transporting the material to the target partition wall, the material is stored in the target partition wall with the fork member of the stacker crane, and at the time of removal, the stacker crane is moved up and down while moving in the circumferential direction, The material is taken out by extending the fork member at the intended partition wall and supplied to the bottom of the shaft.

However, in the case of using such a stacker crane and a fork member to supply a material to a partition wall of a shaft, the sectional shape of the shaft is limited to a circle, and the material is placed in a shaft having an arbitrary shape. It is difficult to store.

[0007] Further, since the stacker crane moves in the circumferential direction in the shaft, space in the vertical shaft equipment such as an elevator, an emergency stair, a path for carrying in and out of soil and the like for employees to enter and exit the shaft. Can not be secured.

Further, when the material is transported into the shaft, the material is taken into the stacker crane by using a fork member from the bogie at the supply port at the upper end of the shaft, and further, each partition wall is formed by using the fork member from the stacker crane. It is necessary to take the material stored in the partition wall into the stacker crane with a fork member, transport the material to the bottom of the shaft, and then transfer it to the bottom side of the shaft with a fork member. Requires a great deal of time and effort.

Further, in such a transport state, when stocks are to be stocked by effectively utilizing the empty space on the ground or the like, it is necessary to transfer the stock from the stock position to the bogie further, and the time and effort for the transfer are further increased. It will increase.

[0010] It is an object of the present invention to reduce the area of ground land by efficiently storing materials in a shaft of an arbitrary shape while sufficiently securing a space necessary for use in other applications in the shaft. It is to plan.

Another object of the present invention is to enable loading and unloading between ground equipment and a stock area and between a stock area and a bogie below a shaft without reloading materials.

Still another object of the present invention is to make it possible to stock a shaft in an arbitrarily arranged shaft and to make effective use of empty space.
