Abstract

PURPOSE:To facilitate arrangement of pipes by a method wherein a plurality of pipe bodies bundled by means of a tube bed is placed on a truck having casters arranged on both sides of the under surface of a bed plate and expandably in a radial direction from the center of a tunnel and brought into contact with the peripheral wall of the tunnel and the pipe bodies are moved within the tunnel for pipings in arrangement of covering pipes for an electric wire. CONSTITUTION:A truck 8 comprises a bed plate 8A; and casters 8B protruded in a radial direction from the both sides of the under surface of the bed plate 8A and expandable. The caster 8B is expandably formed by using a main pipe 81B, a slide lever 83B having a roller 82B located at its tip, and a stopper screw 84B, and moved in a tunnel 1 in a state to bring the roller 82B into contact with the peripheral wall 1A of the tunnel 1. A plurality of flexible tubes 5A and 5B bundled together by means of tube beds 4A and 4B are placed on a truck 8 and are moved in the tunnel 1 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. 5, 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 (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. 5, the tubular 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 dangerous and difficult, and with the method shown in Fig. 6, it is troublesome to put earth and sand or 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 plumbing method in which the vehicle is mounted on the bridge and moved inside the tunnel (1) with a circular cross section, the carriage (8) is pulled out from the base plate (8A) and the left and right sides of the bottom surface of the base plate (8A). (1) consists of casters (8B) that come into contact with the peripheral wall (1A), and the left and right casters (8B) are the caverns.
(1) A pipe construction method is provided which is arranged on the parabola L from the center P and is expandable and contractible.

[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 casters (8B) on the left and right of the carriage (8) are tube bodies (5A, 5B) focused on the tube base (4A, 4B).
The length is adjusted according to the dimension of (1) and the length is adjusted, and then contacted with the peripheral wall (1A) of the tunnel (1). The casters (8B) on the left and right are tunnels
Since it is located on the parabola L from the center P of (1), the load of the truck (8) is evenly applied to the left and right casters (8B). Therefore, the carriage (8) is balanced on the left and right during movement and does not swing.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to one embodiment shown in FIGS. 1 to 4. (1) is a tunnel cut in the ground G,
A concrete surrounding wall (1A) is enclosed. (8) is a trolley, which is composed of a base plate (8A) and casters (8B) extended from the left and right sides of the lower surface of the base plate (8A), and the casters (8B)
Is a stem pipe (81B), a sliding rod (83B) with a roller (82B) slidably fitted to the stem pipe (81B), and is screwed to the stem pipe (81B) Stopper screw (84B)
2 and are arranged on a parabola L from the center P of the tunnel (1) and open at an equal angle θ. The roller (82B) of the caster (8B) is in contact with the concrete peripheral wall (1A) of the tunnel (1).

Reference numerals (5A, 5B) are flexible corrugated tubes made of plastic, which are bundled by the nozzles (4A, 4B), and the nozzles (4A, 4B) are bound by the band (4C). And the nozzle (4A, 4B) is mounted on the base plate (8A) of the carriage (8),
It is bound by wires (10).

In the above structure, a plurality of flexible tubes (5A, 5B) bundled by the nozzles (4A, 4B) are placed on the carriage (8). ), The sliding rod (8B) of the caster (8B) depends on the dimensions of the flexible tube (5A, 5B).
3B) to the trunk pipe (81B) and slide the stopper screw
(84B) tightens and fixes the caster (8B) to expand and contract to adjust the length, and then the carriage (8) is closed.
(1) Move the inside to pipe the flexible tubes (5A, 5B). At this time, the roller (82B) of the caster (8B) is the cutaway (1).
Although it rolls by contacting the concrete peripheral wall (1A), the caster (8B) is located on the parabola L from the center P of the tunnel (1). )
The load is evenly distributed, the left and right sides of the carriage (8) are balanced, and swinging is prevented.

[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.
