Abstract
The utility model relates to a suction pile mat type self-lifting platform which comprises an upper-portion platform, a mat and a pile foundation. By adopting the suction pile foundation, the requirement for using the platform as a fixed platform can be met, and the safety of the platform bearing the environmental force effect for a long period of time is ensured. By adopting a mode that suction piles and mats are combined, the mobile transfer capacity of the platform is achieved, and the platform is convenient to install and low in cost. In addition, the platform has the advantages of movable and fixed platforms, functions of the self-lifting platform are increased, the safety of marine operation of the platform is improved, the platform can be recycled, and the economic benefit is high. By adopting exhausting and water injection pipelines, exhausting and self sinking of the suction piles and overall structure leveling in the suction force injection process are achieved.
Description
Technical field
The utility model relates to a kind of self elevating platform, particularly about a kind of self elevating platform with suction pile and settling type structure.
Background technology
Along with offshore oil resource is continually developed, self elevating platform has obtained the wide application of sending out.Traditional self elevating platform adopts shoe or mat basis, driving depth is more shallow, and skid resistance is poor, is difficult to bear larger environmental forces, therefore generally, only as mobile drilling platform or supporting platform, migrate to other marine site at several Nian Houzai of a certain marine site operation and work on.Some settling type self elevating platforms are provided with anti-skid pile, but as adopted driving into type stake, the marine set-up time is long, and have reduced the moving transfer ability of platform machine; As adopted, machinery is heavy pulls out formula anti-skid pile, mechanical device complexity, and expense is very high; As adopted the sinking formula anti-skid pile that draws water, need the underwater units such as submersible pump and relevant underwater operation.Shoe or mat adopt the method being directly pressed into, and it is larger that driving depth is affected by soil property, enter mud too shallow, can not meet the requirement of opposing environmental forces operation; Enter mud too dark, the migration of pile pulling in the future can run into larger difficulty.
Present patent application has proposed a kind of structural shape and mounting method of suction pile settling type self elevating platform just under this background.
Utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of suction pile settling type self elevating platform, by adopting suction pile basis, can implementation platform as the requirement of fixed platform, ensured that platform bears the safety of environmental forces effect for a long time; By adopting suction pile and mat combining form, realize the moving transfer ability of platform machine, easy for installation and expense is lower, and had advantage portable and fixed platform concurrently simultaneously, and expand self elevating platform function, improve the safety of platform operation on the sea, can reuse, economic benefit is high; By adopting exhaust and water injecting pipeline, realize suction pile exhaust and drowned oneself, and the Integral levelling of structure in suction penetration process.
The purpose of this utility model is realized by following technical scheme:
Suction pile settling type self elevating platform, includes upper brace, mat, pile foundation, and upper brace is provided with several lifting gears, is provided with several spud legs in lifting gear
,it is characterized in that described spud leg bottom is connected with described mat, described mat and described pile foundation upper group to and be connected mechanically, described pile foundation adopts suction pile, the overall structure that described suction pile and described upper brace, described mat are combined to form, can realize in suction penetration process for described integrally-built leveling.
Described suction pile can be used as anti-skid pile and long-time bearing basis, thereby makes described upper brace can be used as fixed platform.
Described suction pile and described mat can be used according to depth of water various combination with described upper brace, use described upper brace and described mat in shallow water, and described mat, as basis, is not used described suction pile; In deep water, use described upper brace, described mat and described suction pile, described suction pile is as basis.
Described suction pile top is provided with gas exhaust piping, water injecting pipeline, is connected with pump valve and control system waterborne, can realize exhaust and drown oneself and real-time leveling function.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, by adopting suction pile basis, can implementation platform as the requirement of fixed platform, ensured that platform bears the safety of environmental forces effect for a long time; By adopting suction pile and mat combining form, realize the moving transfer ability of platform machine, easy for installation and expense is lower, and had advantage portable and fixed platform concurrently simultaneously, and expand self elevating platform function, improve the safety of platform operation on the sea, can reuse, economic benefit is high; By adopting exhaust and water injecting pipeline, realize suction pile exhaust and drowned oneself, and the Integral levelling of structure in suction penetration process.
Below in conjunction with drawings and Examples, the utility model is described further.
