Described suction pile top is provided with gas exhaust piping, water injecting pipeline, is connected with pump valve waterborne and control system, can realize exhaust and drown oneself and real-time leveling function.
The mounting method of described suction pile settling type self elevating platform, comprises the following steps:
(1) upper brace and mat are under build the side after water, from floating in water, by tugboat towage to anchorage, with crane barge by suction pile and mat group to and be mechanically connected, by overall to upper brace, mat and suction pile towage to installing marine site, and carry out water surface location;
(2) upper brace transfers spud leg by lifting gear, and suction pile relies on it to reentry mud, after reaching stake soil air-proof condition, opens suction pile top vent pipeline, makes suction pile under suction function in injection ocean bottom soil;
(3), by controlled suction stake top vent pipeline and water injecting pipeline, adjust the driving depth of each suction pile, thus adjustment upper brace, mat and and the levelness of suction pile entirety;
(4), after suction pile is in place, by lifting gear upper brace risen to design height and by pile leg locking.
Beneficial effect of the present invention: the present invention, owing to adopting technique scheme, by adopting suction pile basis, can be used as the requirement of fixed platform by implementation platform, ensure that platform bears the safety of environmental forces effect for a long time; By adopting suction pile and mat combining form, achieving platform machine and moving transfer ability, easy for installation and expense is lower, and had the advantage of movable type with fixed platform concurrently simultaneously, extend self elevating platform function, improve the safety of platform operation on the sea, can reuse, high financial profit; By adopting exhaust and water injecting pipeline, achieving suction pile exhaust and drowning oneself, and the Integral levelling of structure in suction penetration process.
