Abstract
The invention discloses an intertidal belt submarine cable paving method which comprises the following steps: (1) at high tidal level, drawing a shallow draught flat-bottomed barge with cable to a starting position of circuit in which submarine cable is needed to be paved; (2) placing a cable guiding cage located at barge tail between seawater and beach face; (3) releasing the submarine cable to the beach face from the cable guiding cage through a guiding and twisting rack on the barge; and (4) burying the submarine cable to needed depth through a paving device. By the intertidal belt submarine cable paving method, the problem of intertidal belt submarine cable paving is solved, construction cost is greatly lowered, and submarine cable construction process is simultaneously optimized.
Description
Technical field
The present invention relates to the ocean engineering industry of offshore wind farm industry, relate in particular to sea, a kind of intertidal zone cable laying method.
Background technology
The intertidal zone is between the high and low tidal level of spring tide, the area that is submerged and exposes with tiding.According to preresearch estimates, the intertidal zone annual mean wind speed can reach the 6-7 meter per second, so possesses utilizable wind energy in the intertidal zone.
Wind energy turbine set gets between blower fan and the blower fan in the intertidal zone, needs to connect through submarine cable (extra large cable), and its buried depth degree of depth is all more than 2 meters.But, overbank that flood tide in the intertidal zone, the beach is revealed in ebb, and the depth of water only has the characteristic of 3-5 rice at the incoming tide, has determined sea, conventional coastal waters cable construction technology not to be suitable for the intertidal zone.
Therefore, need provide sea, a kind of intertidal zone cable laying method to address the above problem.
Summary of the invention
In order to address this problem, the invention discloses sea, a kind of intertidal zone cable laying method, said method comprising the steps of: (1) utilizes the start bit of hawser traction shallow draft flat-bottomed barge to the circuit that needs the extra large cable of laying when high tide level; The fairlead cage that (2) will be arranged in stern is put into seawater to beach face; (3) extra large cable being turned round frame through leading on the barge puts from fairlead cage to beach face; (4) bury extra large cable underground the degree of depth through installation apparatus to needs.
Preferably, the installation apparatus in the said step (4) is the waterpower burying machine, and said waterpower burying machine is arranged on an end of said fairlead cage.
Preferably, in the said step (4), utilize the high pressure water impact beach face of waterpower burying machine ejection, extra large cable is buried underground the degree of depth of needs.
Preferably, the installation apparatus in the said step (4) is a crawler-mounted excavator.
Preferably, in the said step (4), utilize crawler-mounted excavator to bury extra large cable underground the degree of depth when revealing the beach on the ebb to needs.
Sea, intertidal zone of the present invention cable laying method has solved the problem that the extra large cable in zone, intertidal zone is laid, and has reduced construction cost greatly, has optimized extra large cable construction technology simultaneously.
In the summary of the invention part, introduced the notion of a series of reduced forms, this will further explain in the embodiment part.Content part of the present invention does not also mean that key feature and the essential features that will attempt to limit technical scheme required for protection, does not more mean that the protection range of attempting to confirm technical scheme required for protection.
Below in conjunction with accompanying drawing, specify advantage of the present invention and characteristic.
