Abstract
The utility model relates to a cylindrical negative pressure based device with an internal sack made of steel, which is used for building platforms in very shallow sea areas or intertidal zone regions within 5-meter water-depth line in sea charts. The cylindrical negative pressure based device is composed of a platform 1, a conduit frame 2, and cylinder bases 3, wherein, the platform 1 is positioned on the conduit frame 2 for supporting the platform; the lower part of the conduit frame 2 is respectively connected with four cylinder bases 3. The utility model can implement float and wet drag through characteristics of self structure; the platform can completely keep self stability, and can be dragged by a minor operating ship; the drag force is small. The utility model can completely enter shallow sea water areas that conventional offshore operating ships are difficult to enter, and can enter intertidal zone regions by taking tide.
Description
The utility model belongs to ocean engineering, relates to a kind of at the capsula interna steel barrel shape negative-pressure foundation device of 5 meters fathom curves of sea chart with interior utmost point shallow sea area or area, intertidal zone construct platform.
At 5 meters fathom curves of sea chart with interior utmost point shallow sea area or area, intertidal zone, has its special environmental quality, be that the depth of water is shallow, tidal range is big, ground is soft, alluvial is serious, general marine operation ship, crane barge are because drinking water is bigger, basically can't enter this waters, make this zone become the area in hardship of offshore oil exploration and exploitation.No matter drilling platform (ship), still oil production platform (ship), enter this marine site all needs special design and equipment, as shallow draft design, seat beach operation etc.Especially 2 meters depth of waters with interior area, but almost do not have the ship of construction operation to enter at present.Den Norske Stats Oljeselskap a.s. (Statoil Group) has used bucket foundation in 1994 on the four leg stake Europipe 1611-E platforms of the 70m depths in the North Sea, producing negative pressure by pump suction cylinder maritime interior waters sinks in the mud, replaced original marine pile foundation, but state's outer platform generally is applied to than the territory, deep-sea, and construction operation ship that all need be bigger carries out construction operation, must be with crane barge etc. as the deck barge of shipping platform, platform base, and these ships can not pass through in the shallow water territory.
It is a kind of at the capsula interna steel barrel shape negative-pressure foundation device of 5 meters fathom curves of sea chart with interior utmost point shallow sea area or area, intertidal zone construct platform that the purpose of this utility model is to provide.
The utility model is achieved in that by platform 1, jacket 2, bucket base 3 to be formed, and platform 1 is arranged on the jacket 2, and jacket 2 bottoms are connected with bucket base 3.
The utility model also adopts following technical scheme: in the bucket base 3 air bag 4 is arranged.
Air bag in the bucket base 3 can be one, also can be more than one.
On the bucket base 3 security strip 7 is arranged.
Buoyancy aid when advantage of the present utility model is to utilize the staving of cartridge type negative-pressure foundation self to drag as platform is wet.In bucket, add interior air bag, the pressure that keeps barrel interior gas, make and guarantee a certain amount of space in the bucket, provide a certain amount of buoyancy to platform, so that enforcement towage, can regulate the balance and stability in flat-bed draft and the platform towage, to adapt to the different depth of waters in different waters by regulating the pressure of air bag simultaneously.In addition, the inflation floating after also can realizing at the bottom of the barrel shape negative-pressure foundation seat, and then the displacement of implementation platform and repeated usage.
The characteristics that the utility model can have by self structure realize floating, wet dragging, and platform can keep the stable of self fully, adopt less workboat just can drag platform, and gradeability is less.Can enter the shallow water along the coast that conventional marine operation ship is difficult to enter fully and take advantage of tide to enter the area, intertidal zone.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model bucket base;
Fig. 3 is the birds-eye view of the utility model bucket base.
Below in conjunction with accompanying drawing the utility model is further described:
Be made up of platform 1, jacket 2, bucket base 3, platform 1 is arranged on the jacket 2, in order to support platform, jacket 2 bottoms are connected with four bucket bases 3 respectively.
In the staving of bucket base, be provided with and the essentially identical air bag 4 of staving diameter, the height of air bag 4 is slightly shorter than the height of bucket base, main like this is when guaranteeing in air bag 4 inflation, air bag 4 can not given prominence to bucket base 3, air bag 4 can not touch the end prior to bucket base 3 than the towage of shallow water territory the time, avoids the sharp objects in seabed that air bag 4 is punctured.
Air bag in the bucket base 3 can be one, also can be more than one.
On the bucket base 3 security strip 7 is arranged.
