Abstract
The invention discloses a simple cylindrical foundation platform capable of being installed separately. The simple cylindrical foundation platform comprises three or four cylindrical foundations. The cylindrical foundations are detachably matched with jacket legs in the axial direction, and the jacket legs are connected to form a jacket. An upper-portion module is arranged on the top of the jacket. According to the simple cylindrical foundation platform, the cylindrical foundations and the jacket capable of being installed separately can be separately built. In the installation process, the cylindrical foundations at the lower portion are installed firstly, then the jacket is installed in a hoisting mode, the jacket legs are inserted into guide vertical columns through horn mouth structures, and finally, grout is poured in the bracket legs to fix the bracket legs. According to the simple cylindrical foundation platform capable of being installed separately, the cylindrical foundations at the lower portion and the jacket can be installed separately, and therefore use of large floating crane resources is avoided, engineering operation is relatively simple and convenient, the engineering investment is lowered, and the economic benefit is increased.
Description
Technical field
The present invention relates to a kind of cylindrical foundation simple platform being removably installed, belong to field of ocean engineering.
Background technology
Along with increasing considerably of China's oil resources consumption, national energy strategy is subject to very large challenge, and fast Development China coastal seas petroleum resources receive much concern cost-effectively.Multi-bucket is because its construction cost is lower and the advantage such as can reuse, more and more being applied in the object of construction production that in limit, coastal waters, small field and some trial production modes are developed oil field.
At present, the multi-bucket using is both at home and abroad mostly three leg platforms, and jacket leg and bottom cylinder base are welded to connect, because the weight of cylinder base is also larger, cause like this jacket gross weight generally larger, need to employ large-scale floating crane resource, increase jacket installation construction cost.Therefore design a kind of multi-bucket being removably installed and be undoubtedly necessaryly, can save large-scale floating crane resource, from sea, install cost saving, China's exploitation of oil-gas field is had great importance.
Summary of the invention
The object of this invention is to provide a kind of cylindrical foundation simple platform being removably installed, cylindrical foundation simple platform of the present invention can be saved construction ship resource, reduces engineering comprehensive cost, increases economic benefit.
The cylindrical foundation simple platform being removably installed provided by the present invention, comprises 3 or 4 cylindrical foundations;
Described in each, the axially upper of cylindrical foundation can be dismantled and coordinate with jacket leg, and formation jacket is connected between described jacket leg; The top of described jacket is provided with upper chunk.
In described cylindrical foundation simple platform, described in each, the axial of cylindrical foundation is provided with a guide upright post, and described jacket leg is inserted in described guide upright post, and the effect of described guide upright post is location and fixing described jacket.
In described cylindrical foundation simple platform, the upper end open of described guide upright post is tubaeform, is convenient to the installation docking of described jacket.
In described cylindrical foundation simple platform, described guide upright post is fixed on by several floors in the cavity of described cylindrical foundation, as can by floor as described in 8 by as described in cylindrical foundation inwall and as described in the outer wall of guide upright post be welded to connect.
In described cylindrical foundation simple platform, between a plurality of described guide upright posts, by horizontal bars, support, above-mentioned setting can increase the rigidity of described bucket foundation and stability, and then forms an overall structure with described cylindrical foundation.
In described cylindrical foundation simple platform, described cylindrical foundation is 3, and 3 described cylindrical foundations are triangularly arranged, to increase the stability of described simple platform.
In described cylindrical foundation simple platform, described cylindrical foundation is 4, and the arrangement that is square of 4 described cylindrical foundations, to increase the stability of described simple platform.
In cylindrical foundation simple platform of the present invention, the cylindrical foundation being removably installed and jacket can separately be built, in installation process, first the cylindrical foundation of bottom is installed, then jacket is installed in lifting, jacket leg inserts in guide upright post by bell-mouth structure of air, and in last jacket leg, grouting is fixing.
Cylindrical foundation simple platform tool of the present invention has the following advantages:
The cylindrical foundation simple platform that the present invention is removably installed, bottom cylindrical foundation and jacket can be distinguished independent installation, thereby avoid using large-scale floating crane resource, relatively simple and convenient in engineering operation, reduce construction investment, increase economic benefit.
