Preferably, the distance between described warning line segment and vulnerable section of described submarine optical fiber cable is 100 meters.
Another technical scheme of the present invention there is provided a kind of construction method of submarine optical fiber cable special protection paragraph warning line guard system described above, it is characterized in that, comprises the following steps:
The first step, mark on submarine optical fiber cable need warning vulnerable section, be positioned at the route of the warning line segment of its both sides according to the Position Design of vulnerable section;
Second step, cement pouring weight are connected with the release device on cable construction operation ship by FS final spice release, and cement pouring weight is also provided with signal transducer, and wire rope or the one end of submarine optical fiber cable had no value for use are connected with cement pouring weight; By release device, cement pouring weight is released on the route location being positioned at vulnerable section of side of design;
3rd step, according to warning length adjustment wire rope corresponding to route or the length of submarine optical fiber cable that has no value for use;
4th step, the operation process release wire rope adopting twisting resistance release or the other end of submarine optical fiber cable had no value for use, connect this end and another block cement pouring weight, another block cement pouring weight is connected with the release device on cable construction operation ship by FS final spice release equally, another block cement pouring weight is also provided with signal transducer, by release device, cement pouring weight is released on the route location being positioned at vulnerable section of side of design;
5th step, employing complete the construction operation of the warning line segment of the opposite side of vulnerable section to submarine optical fiber cable with second step to the method that the 4th step is identical;
6th step, use underwater robot carry out a backlash to two sections of warning line segments and bury operation, to ensure that the depth of burying is shallower than vulnerable section.
Preferably, after said first step, and before described second step, also comprise: utilize underwater robot to detect route.
Preferably, described cement pouring weight is also provided with ball float.
The present invention has set up warning line segment in the both sides of vulnerable section of submarine optical fiber cable, accurately can protect submarine optical fiber cable like this, substantially increase the safety of submarine optical fiber cable.
Accompanying drawing explanation
Fig. 1 is the layout schematic diagram of warning line segment;
Fig. 2 is cement pouring weight release schematic diagram.
Detailed description of the invention
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
As shown in Figure 1; a kind of submarine optical fiber cable special protection paragraph warning line guard system provided by the invention; comprise the warning line segment 2 of vulnerable section of 1 both sides being positioned at submarine optical fiber cable; guard against the wire rope that line segment 2 comprises a predetermined length or the submarine optical fiber cable had no value for use, be respectively equipped with cement pouring weight 3 at wire rope or submarine optical fiber cable two ends for every section.
The Specific construction step of above-mentioned warning line guard system is:
The first step, before cable ship leaves female port, start pre-cast concrete pouring weight 3, cement pouring weight 3 need be installed and be convenient to cable ship and be released in suspension ring on sea bed.
Second step, cable ship, after receiving the requirement of submarine optical fiber cable fault restoration, load the cement pouring weight 3 needed for warning line, and can be used for drawing the wire rope of several kilometers of warning line or short-range submarine optical fiber cable.
3rd step, cable ship carry out normal submarine optical fiber cable repair after arriving fault in-situ.
4th step, after the reparation section of submarine optical fiber cable uses underwater robot punching to bury, mark vulnerable section 1 of required warning.
5th step, according to above route list, in 100 meters, the side of vulnerable section 1 of submarine optical fiber cable, release underwater robot carry out route exploration.
6th step, the release device used on cable ship, and the FS final spice release 4 be connected on cement pouring weight 3 and signal transducer 5, be discharged on the route location of design by cement pouring weight 3, cement pouring weight 3 be also connected with ball float 6.
