Description

CABLE PROTECTING DUCT USING SUB-PROTECTING DUCTS HAVING THE SAME STRUCTURE

The present invention relates to cable sheaths, in particular submarine cable sheaths, and more particularly to cable sheaths which improve the working efficiency by using sub-sheaths of the same structure.

Cable sheaths, for example submarine cable sheaths, mean tubes that protect cables installed on the seabed.

In general, the cable sheath consists of two sub sheaths, and the sub sheaths are fastened using a plurality of bolts or the like. Here, the sub-protection tube has a different structure, and thus the manufacturing cost is increased and the joining operation is not easy, such as using different casting molds.

In submarine cable construction, for example, the length of the cable is significant, which continues to connect a large number of cable sheaths. To this end, sub-protection tubes having different structures are separately disposed on the seabed, and the sub-protection tubes are combined to form cable protection tubes, and the cable protection tubes are continuously connected.

In this process, since the sub-protection pipes are arranged separately and combined to find and combine the sub-protection pipes, the coupling work is inconvenient and the cable construction time may be delayed.

It is an object of the present invention to provide a cable sheath which is easy to combine and can reduce working time.

In order to achieve the above object, the cable protective tube according to an embodiment of the present invention includes a first sub protective tube having a first protrusion and the first receiving portion; And a second sub protective tube coupled to the first sub protective tube and having a second protrusion and a second receiving portion. Here, the first sub-tubes and the second sub-tubes are coupled by the first protrusion is accommodated in the second receiving portion and the second protrusion is received in the first receiving portion, the first protrusion is the second protrusion It has the same structure as the protrusion, and the first accommodating portion has the same structure as the second accommodating portion.

Sub protection tube of the cable protection tube implemented by combining the sub protection tubes of the same structure according to an embodiment of the present invention is a body portion; A first connection part formed at one end of the body part; And a second connection portion formed at the other end of the body portion. Here, a protruding portion is formed at one side of the first connecting portion, and an inverted “c” shaped receiving portion is formed at the other side of the first connecting portion.

Since the sub-protective tubes used in the cable protective tube according to the present invention have the same structure, the production cost is reduced as well as a single casting mold is required, and the operation can be convenient.

In addition, since the sub protection tubes can be combined with a simple operation of inserting the protrusions of the sub protection tubes into the corresponding receiving portions, the coupling can be considerably easy and the working time can be considerably shortened.
