Abstract

PURPOSE:To facilitate arrangement of pipes by a method wherein a plurality of pipe bodies bundled together by means of a tube bed are placed on a truck comprising casters protruded from the under surface of a bed plate toward both sides and a stay sliding over a guide groove formed in the lowermost part of a tunnel and moved in the tunnel for arrangement of pipes, in arrangement of pipes in a tunnel for a covering pipe for an electric wire. CONSTITUTION:A truck 8 comprises casters 8B protruded from the under surface of a bed plate 8A toward both sides and provided at a lower end with respective rollers 81B; and a stay 8C protruded downward from the central part of the bed plate 8A. A truck 8 is moved in a tunnel 1 in a state that the rollers 81B are brought into contact with the peripheral wall 1A of the tunnel 1 and the T-shape part 8D of the tip of the stay 8C is fitted in the guide groove of a rail 9 installed on the peripheral wall 1A. A plurality of pipe bodies 5A and 5B bundled together by means of tube beds 4A and 4B are placed on the truck 8 and moved in the tunnel 1 by means of the casters 8B and the stay 8C for arrangement of pipes.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of piping a plurality of pipes in a tunnel.

[0002]

BACKGROUND OF THE INVENTION 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. 4, a rail (2) is laid on the uppermost part of the tunnel (1), and a rope (3) is hung from the rail (2) to a nozzle (4). Multiple bundled tubes
(5) is supported and guided by the rail (2) through the rope (3) to move the pipe body (5) in the tunnel (1), or as shown in FIG. Fill the bottom of 1) with earth and sand or concrete (6) to make the top flat, and place the nozzle on it.
A method of running a trolley (7) on which a plurality of pipes (5) bundled in (4) are mounted was adopted.

[0004]

However, in the method shown in FIG. 4, 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 work of suspending the pipe body (5) and the nozzle (4) is also dangerous and difficult, and with the method shown in Fig. 5, it takes time and effort to put soil and concrete (6) on the bottom of the tunnel (1). Work is required.

[0005]

[Means for Solving the Problems] As a means for solving the above-mentioned conventional problems, the present invention provides a carriage (8) for a plurality of pipe bodies (5A, 5B) focused by a pipe base (4A, 4B). In the piping construction method in which the carriage is mounted on and moved in a tunnel (1) with a circular cross section, the carriage (8) is a base plate (8A) and casters that are extended from the bottom left and right sides of the base plate (8A). (8B) and a pillar (8C) extending from the center, and the pillar (8C) slides in the guide groove (9A) of the rail (9) laid at the bottom of the tunnel (1). It is intended to provide a piping method that is freely inserted.

[0006]

[Operation] A plurality of pipes (5A, 5B) are bundled on the pipe base (4A, 4B) and mounted on the carriage (8), and the carriage (8) is passed through the casters (8B) to the tunnel (1). ) Move inside. The caster (8B) of the truck (8) abuts on the peripheral wall (1A) of the tunnel (1), and the column (8C) fits into the guide groove (9A) of the rail (9) of the tunnel (1).
(8) Prevent left and right swing. It is easy to increase the strength of the dolly (8) and it is possible to use heavy pipes (5A, 5B)
Withstands (4A, 4B).

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to one embodiment shown in FIGS. 1 to 3. (1) is a tunnel cut in the ground G,
A concrete surrounding wall (1A) is enclosed. A rail (9) having a guide groove (9A) is laid at the bottom of the tunnel (1). (8) is a dolly, which is a base plate (8A), casters (8B) with rollers (81B) attached to the lower ends of the base plate (8A) and rollers (81B) at the lower end, and a support (8C ) And the caster (8B) is in contact with the concrete peripheral wall (1A) of the tunnel (1), and the tip T-shaped portion (8D) of the column (8C) is the tunnel.
It is fitted in the guide groove (9A) of the rail (9) of (1).

(5A, 5B) is a flexible corrugated tube made of plastic, which is focused by a nozzle (4A, 4B), and the nozzles (4A, 4B) are piled up in two stages to trolley (8 ) Is mounted on the base plate (8A) and is bound by the wire (10).

In the above construction, the pipe (4A,
The carriage (8) on which a plurality of flexible tubes (5A, 5B) bundled by 4B) are mounted is moved, and the flexible tubes (5A, 5B) are piped. At this time, the rollers (81B) of the casters (8B) should be on the tunnel (1).
Abut on the concrete peripheral wall (1A) of the
The T-shaped part (8D) of C) is the guide groove (9) of the rail (9) of the tunnel (1).
Insert into A) to prevent the bogie (8) from swinging left and right.

[0010]

Therefore, in the present invention, the piping into the tunnel can be extremely easily and easily performed, and the construction period can be shortened.
