DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to relates to a carriage for use in method for pipe a plurality of pipes into the tunnel.

[0002]

BACKGROUND ART When a pipe body such as a covering pipe for covering an electric wire, a communication line, an optical fiber or the like is laid in the ground, a tunnel is excavated by, for example, a shield construction method, and a concrete wall is stretched on the tunnel. However, a construction method in which a pipe is piped is adopted.

[0003]

2. Description of the Related Art Conventionally, as shown in FIG.
The rail (2) is laid on the top of the rail (2), and the rope (3) suspended from the rail (2) supports a plurality of tube bodies (5) that are focused on the nozzle (4), and the rope (3) ) Via a rail (2) to move the pipe (5) in the tunnel (1), or as shown in Fig. 6, place concrete (6) on the bottom of the tunnel (1). Flatten the upper surface, and stub (4) on it
A method of running a trolley (7) on which a plurality of pipes (5) that are focused on each other are placed was adopted.

[0004]

However, in the method shown in FIG. 5, the tube body supported by the strength of the rope (3) is used.
The weight of the (5) and the nozzle (4) is limited, and the rope (3)
The operation of suspending the pipe body (5) and the nozzle base (4) is also dangerous and it is difficult to move the pipe body (5) in the tunnel (1). In that case, it takes a lot of work to put concrete (6) on the bottom of the tunnel (1).

[0005]

Means for Solving the Problems As a means for solving the above-mentioned conventional problems, the present invention mounts a plurality of bundled pipe bodies (5A, 5B) on a carriage (8) and has a circular cross section. With a trolley (8) used for the piping method of moving and piping inside the tunnel (1)
I Oh,該台wheel (8) is a base plate and (8A), and casters (8B) which Sashidesa from該台plate (8A), surrounding frame provided on the base plate (8A) and (8C), the The present invention provides a trolley for use in a piping construction method , which comprises a support frame (8D) that is extended from the four corners of a surrounding frame (8C) and can be expanded and contracted.

[0006]

[Operation] A plurality of pipes (5A, 5B) are bundled on a pipe base (4A, 4B) and mounted on a carriage (8), and a pillar (8D) of a frame (8C) of the carriage (8) Is stretched and brought into contact with the peripheral wall (1A) of the tunnel (1), and the carriage (8) is moved in the tunnel (1) via the casters (8B). The casters (8B) of the carriage (8) and the columns (8D) of the surrounding frame (8C) contact the peripheral wall (1A) of the tunnel (1) to prevent the carriage (8) from swinging left and right. It is easy to increase the strength of the dolly (8) and it can withstand heavy pipes (5A, 5B) and pipe stubs (4A, 4B).

[0007]

EXAMPLES The present invention will be described with reference to one example shown in FIGS. 1 to 4. (1) is a tunnel cut in the ground G, which is surrounded by a concrete peripheral wall (1A). (8) is a dolly, and is a caster (8B) with a base plate (8A) and a roller (81B) attached to the lower end of the base plate (8A) from the left and right sides of the bottom surface of the base plate (8A).
And the surrounding frame (8C) assembled on the base plate (8A) and the surrounding frame (8C).
C) and the pillars (8D) that are extended from the four corners, and the surrounding frame
(8C) consists of both side frames (81C) and upper frame (82) C, the casters (8B) abut the concrete peripheral wall (1A) of the tunnel (1),
The column (8D) is a base tube having a thread groove inside as shown in FIG.
(81D), a screw rod (82D) screwed to the base pipe (81D), and a bearing (83D) attached to the tip of the screw rod (82D).
D) and the length of the strut (8D) is adjusted by the screwing degree of the screw rod (82D) with respect to the base pipe (81D), and the bearing (83D) of the strut (8D) is connected to the tunnel (1). Make sure it touches the concrete wall (1A).

(5A, 5B) is a flexible corrugated tube made of plastic, which is focused by a nozzle (4A, 4B), and the nozzles (4A, 4B) are stacked in two stages to trolley (8 ) Is mounted on the base plate (8A) and is supported by the surrounding frame (8C).

In the above structure, the pipe (4) is installed in the tunnel (1).
A carriage (8) carrying a plurality of flexible tubes (5A, 5B) bundled by A, 4B) is moved to pipe the flexible tubes (5A, 5B). At this time, the roller (81B) of the caster (8B) and the bearing (83D) of the column (8D) of the surrounding frame (8C) come into contact with the concrete peripheral wall (1A) of the tunnel (1) and roll to move the bogie (8). Prevents left and right swings.

[0010]

[Effects of the Invention] Therefore, in the present invention, piping into the tunnel can be performed very easily and easily, and the construction period can be shortened.
