Description
Technical field
The utility model relates to bottom cable laying technical fields, lead in particular to for intertidal zone land cable
The transfer platform of drawing.
Background technique
Submarine cable is the important power transmission being connected between Offshore Units and land facility and signal transmission facilities.According to
Environmental condition where bottom cable laying construction is different, and submarine cable is usually divided into coastal waters section and logs in section.Each section of difference
Using different targeted technical equipments and construction method.The cable laying of coastal waters section carries out deposited buried construction by paving cable ship；
The cable laying for logging in section generallys use drawing mode: paving cable ship approaches debarkation point anchoring；The submarine cable on cable ship will be spread
End is pulled to land facility terminal along design routing；Then carry out logging in the deposited buried operation of section cable.Log in a section cable laying
After completion, paving cable ship carries out coastal waters section cable laying.
A section cable drawing is logged in order to realize, needs logging in a section cable routing ascender line setting cable drawing channel, and
Inflection point is routed in cable and other necessary position setting several groups pull power-equipment.For logging in characterized by dykes and dams
Section, for section apart from short, one group of drawing power-equipment is arranged in the land of no water logging risk between tide.For being with natural beach
Feature logs in section, and intertidal zone distance needs to arrange several groups drawing power-equipment in intertidal zone, therefore has water logging risk.
In order to avoid water logging equipment, and make cable drawing channel plane absolute altitude when pulling construction period peak level
More than the water surface, need to set up scaffold temporary operating platform and scaffold access.The cable drawing channel of intertidal zone is usually by foot

Power-equipment generally includes to be twisted machine, dragger and generator, dispersion or that concentrates be arranged in scaffold building, upper laying steel
On the temporary operating platform of plate.
The monomer weight for being twisted machine, dragger and generator as drawing power-equipment is larger, and handling installation needs
Biggish haulage vehicle and crane is wanted to cooperate.Since natural beach is with a varied topography and muddy, it usually needs on the way pad soil pave the way to
Installation site is designed, the needs of the transport of drawing power-equipment and lifting installation are just able to satisfy.It is this to transport and pacify from land direction
The usual way of dress, construction earth volume is big, and by tidal effect, the effective time is short, long in time limit, economic cost and time
It is at high cost；In-site installation, contraposition and the debugging for pulling power-equipment simultaneously have also accordingly increased duration and cost；In addition a large amount of
Earthwork the ecology of natural wetland can be caused to seriously affect, again repair be also required to sizable time cost and economy
Cost.Further, since be limited to drauht, can not will drawing power-equipment from marine direction transport to design installation site into
Row installation.
Therefore it provides a kind of intertidal zone logs in a section cable pulling apparatus solution, becomes those skilled in the art and wanted
The important technological problems of solution.
