Description
Technical Field
The invention relates to the technical field of submarine cable laying, in particular to a transit platform for pulling a cable logging in an intertidal zone and an installation method thereof.
Background
Submarine cables are important power and signal transmission facilities that communicate between offshore and land facilities. Submarine cables are generally divided into an offshore section and a landing section according to different environmental conditions in which the submarine cables are laid. Each section adopts different targeted technical equipment and construction methods. Laying the cable of the offshore section by a cable laying ship for burying construction; the cable laying of the landing section usually adopts a traction mode: anchoring the cable laying ship near the landing point; pulling the end of the submarine cable on the cable laying ship to a land facility terminal along a designed route; and then carrying out the burying operation of the logging-in section cable. After the landing section cable is laid, the cable laying ship lays the offshore section cable.
In order to realize the cable traction of the landing section, a cable traction channel is arranged along the cable route of the landing section, and a plurality of groups of traction power equipment are arranged at the inflection point and other necessary positions of the cable route. For a landing section featuring a dike, the inter-tide section distance is short, and a set of traction power equipment is arranged on land without risk of flooding. For landing sections characterized by natural tidal flats, where the distance between the intertidal zones is long, several sets of traction power equipment need to be arranged in the intertidal zones, thus risking flooding. In order to avoid flooding equipment and to enable the plane elevation of the cable traction channel to be above the water surface even at the highest water level during traction construction, a temporary scaffold operation platform and a temporary scaffold channel need to be erected. The cable pulling channel of the intertidal zone is generally composed of a channel erected by a scaffold, a steel plate paved on the channel, and V-shaped riding wheels and H-shaped riding wheels fixed on the steel plate. The traction power equipment of the intertidal zone generally comprises a wringing machine, a traction machine and a generator, which are arranged in a dispersed or concentrated manner on a temporary operating platform of the upper laying steel plate which is erected on a scaffold.
The weight of the single bodies of the wringing machine, the traction machine and the generator serving as traction power equipment is large, and the lifting installation of the wringing machine, the traction machine and the generator needs large transportation vehicles to be matched with a crane. Because the natural beach topography is complicated and muddy, the road is usually required to be paved to the designed installation position by the cushion soil along the way, so that the requirements of transportation and hoisting installation of traction power equipment can be met. The common practice of transportation and installation from land is that the construction earthwork is large, and the method is influenced by tide, so that the effective working time is short, the construction period is long, and the economic cost and the time cost are high; meanwhile, the on-site installation, alignment and debugging of the traction power equipment also correspondingly increase the construction period and the cost; in addition, a large amount of earthwork can have serious influence on the ecology of the natural wetland, and considerable time cost and economic cost are required for the repair. In addition, because of the limited draft of the vessel, the traction power plant cannot be transported from the offshore direction to the design installation location for installation.
Therefore, providing a solution to the cable pulling equipment at the landing section of the intertidal zone is an important technical problem to be solved by the person skilled in the art.
