JPH03270613A - Method for underground wiring of communication wire by using fluid transport pipe - Google Patents

Abstract

PURPOSE:To reduce the cost of underground wiring and to shorten a term of works by laying a communication wire in a hole or space which is made along a longitudinal direction in a part of a body of a fluid transport pipe such as a sewerage, aqueduct, etc., or in a part of a space of the pipe. CONSTITUTION:A communication wire is passed through a hole 5b which is made in a longitudinal direction in a pipe wall of a fluid transport pipe 5 such as a sewerage, aqueduct, etc., or through a space 5a which is made in a longitudinal direction in a part of a space of the pipe. A main track of the communication wire and an incoming line to a consumer 7 are connected at a manhole or handhole 4 and the incoming line is passed in a conduit 6 for the consumer 7.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an underground wiring method for communication lines using fluid transport pipes.

(Prior Art) Conventionally, as a method for wiring communication lines such as telephones to customers underground, there have been two methods: burying communication line pipes underground as shown in Figure 5, and burying pipes for communication lines underground as shown in Figure 6. In Figure 0, where a method of accommodating communication lines in a cable box is used, 1
2 indicates a communication line, 2 indicates a buried pipe that accommodates the communication line, and 3 indicates a cable box.

In the method of burying communication line pipes underground as shown in Figure 5, roads are excavated and the pipes are buried, which requires a large amount of money and requires a long construction period. It took time and caused trouble for traffic and nearby residents. Furthermore, when a new customer arises, it is necessary to excavate the road and bury the pipe again, which takes time to install the communication line.

In the method of burying the cable box shown in Figure 6,
Because a large box is buried in a sidewalk where water, sewer, electricity, gas, etc. pipes are buried, existing pipes must be relocated, and a large amount of excavation is required, requiring a large amount of time and money for construction. was.

(Problems to be Solved by the Invention) The present invention was proposed in order to improve the above-mentioned drawbacks, and its purpose is to provide communication lines to customers in a short time and economically without having to dig the roads again. The purpose is to provide a method for underground wiring.

(Means for solving problems) To achieve the above object, the present invention provides a sewerage system.

Utilizing a fluid transport pipe characterized in that a space is provided along the length in a part of the pipe body or a part of the pipe interior space of a fluid transport pipe such as water supply pipe, and a communication line is arranged in the space. The gist of the invention is a method for underground wiring of communication lines.

(Function) The present invention provides a space for accommodating a communication line in a part of a fluid transport pipe such as a water pipe or a sewer pipe, and by accommodating the communication line in this space, for example, a sewer pipe can be arranged. By doing so, the communication line can be easily installed from underground to the customer without the need to install a pipe for the communication line.

(Example) Next, an example of the present invention will be described. Note that the embodiments are merely illustrative, and it goes without saying that various changes and improvements can be made without departing from the spirit of the present invention.

FIG. 1 shows an embodiment of the present invention, in which 4
is a manhole or handhole for interconnecting communication lines inside, 5 is a transport pipe that accommodates the communication lines and fluid explained in Figure 2 and below, 6 is a storage pipe that accommodates only communication lines, and 7 is a demand pipe. Show the house.

FIG. 2 shows a transport pipe accommodating communication lines and fluid used in the present invention. In the figure, transport pipe 5 is made of concrete, metal such as iron, or plastic, and there is a Hole 5a for water or sewage to flow
A space 5b is provided along the length of the transport pipe. 1 indicates a communication line contained within the space.

As for the work, the communication line that has been laid by the communication line and the transport pipe 5 that accommodates the fluid is branched into the communication line to be distributed by the consumer 7 through a manhole or handhole 4 near the consumer 7. The communication line is wired through a communication line accommodation pipe 6 attached to the customer 7.

Figures 3 and 4 show other embodiments of the transport pipe,
FIG. 3 shows an example in which a space 5b for accommodating a communication line is provided by partitioning the inner surface of the pipe body, and FIG. This is an example.

(Effects of the Invention) As explained above, according to the present invention, a space is provided along the length direction in a part of the pipe body or a part of the pipe interior space of a fluid transport pipe such as a sewer water supply pipe, and the above-mentioned By arranging communication lines in the space, communication lines can be brought from underground to customers at the same time as the construction of fluid transport pipes such as water and sewage lines, resulting in a significant cost reduction when wiring communication lines underground. It also has the effect of shortening the construction period and reducing inconvenience to traffic and surrounding residents.
