The present invention relates to a trough for embedding cables and a construction method thereof, and in particular, a method of installing optical cables by installing 28-30 sets of inner pipes inside a trough in parallel with a road boundary stone or separately installed in a sidewalk block and a road section. It is about.

In general, communication cables are installed on electric poles or buried in the ground in order to maintain and maintain safety.

However, as communication equipment has developed, installation in Jeonju has reached its limit.

Thus, the method of embedding in the ground using cable troughs is expanding.

The conventional cable trough is composed of a main body 2 and a cover 4 having a rectangular cross section with an open top, as shown in FIG. 1, and are manufactured to a certain length using reinforced concrete to increase strength.

The construction of the conventional cable trough made of the configuration as described above is embedded in a plurality of main body in the longitudinal direction on the ground, and after installing the cable, cover the cover to pile up the soil to be the same height as the ground.

Since the reinforced concrete cable trough is heavy and difficult to transport and install, it is easy to be damaged by impact, and its durability is drastically degraded by freezing and melting after installation.

In addition, the cover must be frequently opened and closed for the maintenance of the cable, the cover made of reinforced concrete has a problem that it is difficult to open and close the cover to about 50kg in weight.

Since cables are usually tangled inside the trough, there is a risk of cable disconnection and short circuits when installing or repairing a new cable. There is a problem that is not easy.

In order to solve the problems described above, the trough is installed in parallel with the road boundary stone in the sidewalk block road section, or the trough is installed alone, and 28-30 sets of inner tubes are installed inside the trough for optical cables. The construction work is simple and easy, and the construction input cost is reduced by about 67% of the asphalt section, about 79% of the sidewalk block (marble), and about the sidewalk block (small high-pressure block). It is a 65% reduction construction, and it has good scalability by laying inner pipe of the trough that can be laid easily when laying optical and coaxial cables. Can be installed quickly, and underground cable is easy to install at low cost for processing such as KEPCO, and it is not exposed to the outside. It is a clean environment-friendly facility, and can prevent re-excavation by expanding underground pipelines, and it can be reused when removing troughs, installing optical and coaxial cables by expanding roads, etc. The purpose of the present invention is to provide a cable embedding trough and a construction method thereof.

The cable embedding trough according to the present invention for achieving the above object is a main body consisting of a top plate is open, the bottom plate horizontally integrally formed at the lower end of the left and right side walls and left and right installed at predetermined intervals. And a straight member formed of a cover made of a predetermined cross-sectional shape covering an upper portion of the main body;

The main body is fixedly installed on the left and right side walls of the straight member, the upper part is open, and the left and right side walls are installed on the left and right sides at predetermined intervals, and the bottom plate is integrally formed horizontally with the lower end of the left and right side walls and the upper part of the main body. Left and right rotation connecting member consisting of a cover made of a predetermined cross-sectional shape to cover the;

The main body is fixedly installed on the left and right side walls of the linear member, the upper portion of which is opened, and the left and right side walls are installed at left and right sides at predetermined intervals, and the bottom plate is integrally formed at the bottom with a predetermined length from the top of the left and right side walls. A vertical rotation connecting member configured;

The vertical rotation connecting member is installed, the upper and the left side and the front side wall which is divided in three directions as the opening and the bottom member formed of a main body consisting of a bottom plate horizontally integrally formed at the lower end of the left and right side walls It is done.

In addition, the cable laying trough construction method according to the present invention for achieving the above object comprises the steps of manufacturing each member constituting the trough; Transporting each trough member to an installation site; Digging the installation site to a certain width and depth; Installing a trough body in the trench and reinforcing the free space outside the body of the trough by pouring concrete; Characterized in that the cover is made to cover the trough body.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.
