Abstract
The present invention relates to a barrel-type foundation air-water lifting platform, consisting pile column and ship body with pile column lifting holes, in which the pile column is equipped with rack bar, on the ship body there is a pile-fixing frame with matched toothed pin, the interior of the ship body possesses a balance water cabin. It is characterized by that the lower end of the described pile column possesses barrel-type foundation, and on the barrel-type foundation the charging and discharging air-water pipeline is mounted, and its advantages lie in that it utilizes barrel-type foundation and its charging and discharging air-water pipeline to implement platform lift, can save complex electric hydraulic or mechanical lifting device and matched power equipment of traditional platform, can reduce cost, and can be easily mounted and quickly moved.
Description
The invention belongs to a kind of novel self-lifting type platform in the marine oil and gas development tool.
Traditional jack-up platform general-duty jacking apparatus is electric hydraulic and electric gear rack-and-pinion, these two kinds of jacking apparatus complex structures, and need to be equipped with big power facility, involving great expense, the during-operation service expense is also high.
The objective of the invention is to design a kind of air and water lift platform with barrel-shaped footing, save habitual jacking apparatus, the problem that the complicated jacking apparatus of above-mentioned traditional jack-up platform is produced is satisfactorily resolved.
Technical scheme of the present invention: a kind of air and water lift platform with barrel-shaped footing, form by some piles and hull with pile lift span; Tooth bar is arranged on the pile, wedge bracket and alligator are arranged on the hull, the balance sump is arranged in the hull, it is characterized in that there is bucket base described pile lower end, be equipped with at the bucket base top can be to filling the pipeline of exhaust-water in the bucket.
Principle of work of the present invention: this platform is in towage, pile sinking, jacking and final fixing whole job procedure, and flat-bed hull and relative motion between the pile all are to rely on to fill exhaust-water and cooperate pile and the operation of hull nog realizes in the bucket base of pile.The bucket base that fills exhaust-water plays the hydraulic cylinder effect at this, presses decision jacking ability in it, and its traverse determines top lifting height one time.During the platform towage, the bucket base inflation is from floating, and the hull drinking water is shown in Fig. 3-a.When hull casts anchor enforcement pile sinking in place, then to the bucket base exhaust, make down and put into mud, the step-down of drawing water then makes it to sink to the seabed, shown in Fig. 3-b.Hull jacking subsequently can have dual mode to select, the one, from the seabed jacking, the 2nd, from water surface jacking, shown in Fig. 3-c: from the seabed jacking is to appoint to get one group of diagonal angle pile, pins hull with alligator, then to setting-out in the bucket base that sinks to the seabed, with it from seabed jack-up certain distance, thereby make upper post and hull jacking corresponding height, to go deep into the seabed motionless for another group diagonal angle bucket base in this process, and pile play the guiding role on it.From water surface jacking also is to appoint to get one group of diagonal angle pile, the floating nearly water surface place of its bucket base inflation further to bucket in plenum, with hull jack-up certain altitude, this mode can repeat under the alligator operation cooperates, until satisfying required top lifting height with its surplus buoyancy.In dual mode jacking process, the center of gravity of hull can be harmonious with the centre of form through the adjustment of balance sump, thereby keeps the steady of jacking.Be that the diagonal angle bucket base sinking that will carry out jacking resets and sinks to the seabed at last, with alligator hull and pile locked simultaneously that platform installs and is fixed in the sea and enters normal working, shown in Fig. 3-d.
But the preceence of air and water lift platform with barrel-shaped footing involved in the present invention is 1. bucket bases itself and intrinsic fills the just implementation platform jacking of exhaust-water pipeline, thereby save complicated jacking apparatus and relevant power facility, can reduce the platform cost greatly; 2. platform structure is simple makes easily; 3. platform is installed rapidly, is convenient to resettlement.
Be described further below in conjunction with drawings and Examples

Embodiment: a kind of air and water lift platform with barrel-shaped footing (is seen Fig. 1,2), form by pile (2) and hull (1) with pile lift span, tooth bar (4) is arranged on the pile, there is wedge bracket (5) to be furnished with alligator on the hull, balance sump (6) is arranged in the hull, it is characterized in that there is bucket base described pile lower end, be equipped with at the bucket base top can be to filling the pipeline of exhaust-water in the bucket.Fill exhaust-water lines and comprise diving pump, valve, flexible pipe, link operating console on the hull, belong to the conventional equipment that to buy from the city of interim installation, do not give illustrating among the figure by the bucket base top.The flat-bed hull is the steel structure that plate-girder is formed, and pile and the bucket base thin walled steel structure for being made by steel plate, bucket base top board generally have rib system to strengthen.Flat-bed erection procedure of the present invention is seen Fig. 3-a to Fig. 3-d.
