Abstract
The utility model relates to a barrel type foundation single column structure with a loading tank for supporting platforms, which comprises a barrel foundation. The utility model is characterized in that the barrel foundation adopts a reverse cup type structure. The space above the barrel foundation and below the water surface is a single column with a variable cross section. A ballast tank matches with the single column structure. The center part of the ballast tank is provided with a hole, and the single column structure can pass through the hole. The tank bottom is arranged on the top cover of the barrel foundation. The utility model has the advantages of simple structure of the column body and easy fabrication. The barrel foundation is provided with the ballast tank to carry out the water filling and ballasting processes to satisfy the initial mud entering and sealing conditions, and the whole barrel foundation is ensured to be arranged at the right position. The barrel type single column foundation structure with a loading tank for supporting platforms can be assembled easily and simply and can be moved.
Description
The utility model belongs to the bucket base single pillar structure that has ballast tank that is used for support platform in offshore engineering structure and basic engineering and the construction.
Traditional base form of ocean platform has two kinds of long stake formula and block bottom-sitting types.The advantage of the long pile foundation jacket structure of tradition is prefabricated simple and easy, and it is wide to adapt to soil property; Shortcoming is that the marine set-up time is long, and structure can not be reused.The advantage of gravity type foundation structure is double oil storage and can moves; Shortcoming is prefabricated site requirements height, and it is narrow to adapt to soil property.Adopt bucket formula basis to have advantage rapid, simple and easy and that can move is installed.Bucket base can adopt the suction method to install, but in the top layer soil property under the hard or Very Shallow Water condition, the suction that limited deadweight and Natural Depth can provide is not enough to form the initial penetration into mud air-proof condition and whole basis is in place.
The purpose of this utility model is to design a kind of bucket base single pillar structure that has ballast tank that is used for support platform, and it can not reuse the marine set-up time length of the long pile type foundation of the above-mentioned tradition of mentioning, structure; The prefabricated site requirements height of gravity type foundation, to adapt to soil property narrow; Firmly or under the Very Shallow Water condition bucket base is installed at topsoil, the suction that deadweight that it is limited and Natural Depth can provide is not enough to form the problem that initial penetration into mud air-proof condition so that whole basis can't be in place and is able to more satisfactory solution, is adoptable desirable approach in offshore engineering structure and basic engineering and the construction.
The technical solution of the utility model: a kind of bucket base single pillar structure that has ballast tank that is used for support platform, comprise bucket base, it is characterized in that said bucket base adopts down cup type structure, bucket base is above to below the water surface being the only cylinder of variable cross-section; Have a ballast tank to match with the single pillar structure of bucket base, said ballast tank be shaped as a cylinder, the ballast tank center drilling can pass single pillar structure, a jar end, be seated on the top cover of bucket base.
Using method of the present utility model: before installation, generally ballast tank and single pillar structure are assembled, the one lifting is transferred.Along with the bucket base dive the end promptly in ballast tank water filling make bucket base constantly in the injection soil, in case obtain enough to go into the mud degree of depth and form and apply the just turn on pump operation of drawing water of the required initial sealing condition of suction, be in place up to the basis.
The superiority of the bucket base single pillar structure that has ballast tank that is used for support platform that the utility model is related is: 1. by a ballast tank being installed on bucket base and being satisfied the initial penetration into mud air-proof condition as water injection ballast, guarantee whole basis is in place; 2. foundation structure is simple, makes easily; 3. install rapid, simple and easy and can move.
Be described further below in conjunction with drawings and Examples.
Fig. 1 is the related only post overall structure of the bucket base front elevational schematic that has ballast tank of the utility model.
Fig. 2 is the related bucket base single pillar structure of the utility model vertical cross section figure.
Fig. 3 is the vertical cross section figure of the related ballast tank structure of the utility model.
Wherein 1 is the only cylinder of variable cross-section, and 2 is ballast tank, and 3 is bucket base, and 4 is the inner floor of bucket base, and 5 is the ballast tank centre bore.
Embodiment: a kind of bucket base single pillar structure that has ballast tank (seeing Fig. 1,2,3) that is used for support platform, comprise bucket base 3, it is characterized in that said bucket base adopts down cup type structure, there was deep floor 4 inside when the bucket base yardstick was big; Bucket base is above to below the water surface being the only cylinder 1 of variable cross-section; Have a ballast tank 2 and single pillar structure to match, said ballast tank be shaped as a cylinder, ballast tank center drilling 5 passes single pillar structure, the shape of institute's perforate can be the cylindrical or turbination of variable cross-section, a jar end, be seated on the top cover of bucket base.
Claims (3)
