DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
An embodiment of a construction method using the method will be described with reference to FIGS.
I will tell. FIG. 1 is an external view of a segment, and FIG.
FIG. 1 is a sectional view taken along line II-II of FIG. 1, and FIG.
4 is an enlarged view of the main part of FIG. 3, and FIG.
FIG. 5 is a sectional view taken along line VV of FIG. 4.

As shown in FIG. 1, in the direction connecting one side and the other side, that is, in FIG. , A hollow portion 51a is formed.

Accordingly, the specific gravity of the segment 51 is reduced.

[0013]

As shown in FIG. 3, a gantry 21 is provided on the ground 100. On the gantry 21, a housing 31 is provided. Inside the housing 31, there is provided a driving device 32 whose axis is oriented in the vertical direction.
The rotation shaft 33 of the driving device 32 has a cylindrical shape. A cutter head 34 is provided on the tip side of the rotating shaft 33. A cutter 35 is provided on a front surface of the cutter head 34. A diameter-enlarging cutter 36 is provided on the peripheral edge of the front surface of the cutter head 34 so that the diameter of the shaft 101 can be enlarged. A discharge pipe 37 for discharging earth and sand is connected to the rotation shaft 33 near the drive device 32 so as to be slidable with the rotation shaft 33 in a direction of an axis crossing the axis of the rotation shaft 33. A pump 38 is connected to the discharge pipe 37.

Accordingly, when the driving device 32 is driven, the cutter head 34 rotates, excavating the ground 100, and
8 is driven, the generated earth and sand is
Is discharged from the discharge pipe 37 to the outside. As a result, the shaft 101 is formed on the ground 100.

The gantry 21 is provided with a rail 1 for connecting the outside of the gantry 21 and the vicinity of the rotary shaft 33. The rail 1 is provided with a hoist 2 that can run along the rail 1. Hoist 2 has segment 5
A hook 2a for holding the hook 1 is provided so as to be able to move up and down.

Accordingly, the hoist 2 conveys the segment 51 to the vicinity of the rotating shaft 33.

In this embodiment, the rail 1, the hoist 2, and the like constitute a transfer device.

As shown in FIG. 4, a tubular guide pipe 3 is suspended from the gantry 21 so as to surround the rotation shaft 33. Outside the guide pipe 3 of the gantry 21, a cylindrical frame 4 is vertically provided so as to be coaxial with the guide pipe 3. An elevating body 5 that can move up and down along the guide pipe 3 is fitted to the outer peripheral surface of the guide pipe 3. The elevating body 5 is formed with a flange portion 5a. A frame 4 is mounted on the flange 5a of the lifting body 5.
Is attached to a tip end of a lifting jack 6 provided at the front end.

Therefore, by driving the lifting jack 6, the lifting body 5 moves up and down.

As shown in FIG. 5, on the outer periphery of the elevating body 5,
The bearing 7 is fitted. A rotating shaft 33 is provided on the outer ring of the bearing 7.
There are provided two telescopic jacks 8 for moving the moving arm 8 a in a direction intersecting the axis of the rotary shaft 33 so as to be symmetrical with a line passing through the axis of the rotating shaft 33. The distal ends of the movable arms 8a of the telescopic jacks 8 are connected to ends of support arms 9 bent in a concave shape, respectively. A gripping device 10 for gripping the segment 51 is provided on the distal end side of the support arm 9, that is, below in FIG. A motor 11 that rotates the elevating body 5 around the same axis as the rotation shaft 33 is provided on the flange portion 5 a of the elevating body 5.

Accordingly, the gripping device 10 is turned around the same axis as the rotation shaft 33 by driving the motor 11, and the gripping device 1 is driven by driving the telescopic jack 8.
0 moves along the radial direction of the rotating shaft 33.

In this embodiment, the guide pipe 3, the frame 4, the elevating body 5, the jack 6, the bearing 7, the telescopic jack 8, the support arm 9, the gripping device 10, the motor 11, and the like constitute a lining assembly device in this embodiment. It is doing.

As shown in FIG.
Along the periphery of 2, while holding the segment 51,
A plurality of lining molding devices 12 that can expand and contract in the vertical direction are provided at predetermined intervals.

Therefore, the lining forming apparatus 12 performs lining on the anti-wall 103 of the upright 101 by sending the held segment 51 downward.
In addition, in the figure, 22 is a cart and 104 is water.

An embodiment of a lining construction method using such lining construction equipment will be described below.

The segment 51 transported by the carriage 22 is picked up by the hook 2 a of the hoist 2, moved along the rail 11, and transported to the vicinity of the gripping device 10. The segment 51 is gripped by the gripping device 10, the segment 51 is turned around the rotation shaft 33 by driving the motor 11, and the segment 51 is moved radially outward of the rotation shaft 33 by driving the telescopic jack 8. The segment 51 is lowered by driving the lifting jack 6, and the segment 51 is moved downward.
Is attached to a predetermined lining molding device 12. By repeating this, the segment 51 is assembled so as to form an annular shape along the periphery of the opening 102. The ring-shaped segment 51 is fed into the stand 101 by the lining forming device 12 and provided on the stand wall 103 of the stand 101.

By repeating these series of operations,
The ring-shaped segment 51 is fed into the upright 101 to lining the upright wall 103.

Accordingly, by assembling the segment 51, the lining is applied to the anti-wall 103 of the upright 101, so that not only the transportation of the members required for the lining becomes very easy, but also the hollow portion 51a is formed in the segment 51. Is formed, the specific gravity of the segment 51 is reduced,
The insertion into the water 104 in the stand 101 is also very easy. As a result, the lining can be easily constructed even with a small output device.

Further, the anti-wall 1 is formed while forming the uprights 101.
03 can be lined with the anti-wall 103
This eliminates the need for work such as fixing the ground 100 around the stand 101 for stabilizing the work, and thus greatly simplifies the work and significantly reduces the construction period.
