Description
Technical field
The utility model relates to marine Construction of Support Platform technical field, especially a kind of jacket basis with suction tube
Structure.
Background technique
Currently, jacket is most common structure type in the structure type on ocean engineering basis, it acts as to upper
Portion's facility provides support, and keeps stable, at present predominantly steel structure truss.Jacket-type ocean engineering basis is by jacket
It is placed in mud face, lower end is connect with the pile foundation buried, and the superstructure of ocean engineering is built in the top of jacket.It is in mud face
Below using pile foundation as supporting structure, the embedded depth of pile foundation is bigger, and engineering cost is more high and its construction is complex, applies
Work is long in time limit.For this purpose, someone devises novel foundation structure, the Chinese utility model such as application number 201720012291.5 is special
Benefit, more base truss-like offshore wind power foundation structures of open one kind, including sub-truss, sub-truss top are connected to operating platform
With the mounting flange for connecting superstructure, sub-truss lower end is uniformly connected to several steel suction tubes, the steel suction tube
For the semi-closed structure of top cover and barrel composition, steel suction tube open end is arranged downwards, vertically, the top of the steel suction tube
Cover water flowing and the venthole being equipped with for connecting suction pump valve.Foundation structure disclosed in the patent is easy for installation, is suitable for
A variety of geological conditions, construction efficiency are high, are able to satisfy production needs substantially, still, since its jacket and suction tube are fixed companies
It connects, it is uneven due to being settled in multiple suction tube sinking watchings, it is easy to produce stress rupture jacket overall structure, is influenced whole
Body performance.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, a kind of stable structure, convenient construction are provided
And the not easily damaged jacket frame foundation structure of structure in process of construction.
To achieve the goals above, the technical solution adopted in the utility model is: a kind of jacket frame foundation structure, including inhales
Power cylinder and jacket, it is characterised in that: the suction tube includes main body cylinder and the taper connection cylinder that is connected in main body cylinder, is being bored
Shape connecting cylinder upper end is equipped with first flange disk, and the jacket is made of frame body and the conduit leg being connected on frame body, in conduit
The top of leg is equipped with second flange disk, and the conduit leg is inserted into taper connection cylinder, first flange disk and second flange disk
Between be bolted and be additionally provided with a rubber washer between the two.
Further, the suction tube is made of Steel material.The suction tube is equipped with 3 or 4.
The beneficial effects of the utility model are: structure is not easily damaged in stable structure, convenient construction and process of construction.Specifically
It is and the setting taper connection cylinder by being connected between suction tube and jacket by two ring flanges with rubber pad, it can be with
Allow suitably to deform between jacket and suction tube, jacket is generated due to unbalance stress in reduction suction tube sinking watching
Adverse effect.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the enlarged diagram of part A in Fig. 1.
Fig. 3 is the schematic cross-section of B-B in Fig. 1.
Specific embodiment
As shown in Figure 1-3, a kind of jacket frame foundation structure of the utility model, including suction tube 1 and jacket 2.Its
In, suction tube 1 includes main body cylinder 11 and the taper connection cylinder 12 being connected in main body cylinder, is equipped with first in taper connection cylinder upper end
Ring flange 13.The jacket 2 is made of frame body 21 and the conduit leg 22 being connected on frame body.It is installed on the top of conduit leg 22
There is second flange disk 23, the conduit leg 22 is inserted into taper connection cylinder 12.First flange disk 13 and second flange disk 23 it
Between connected by bolt 3.The rubber washer of an extrudable deformation is additionally provided between first flange disk 13 and second flange disk 23
4。
Specifically, the suction tube 1 is made of Steel material.In addition, the suction tube 1 is equipped with 3 or 4.Certainly, suction
The number of cylinder 1 can also be arranged according to the actual situation.
The mass-type foundation of the utility model can make assembling by land, reduce foundation construction difficulty, be suitable for compared with flood
Sea area deep, supporting course buried depth is shallower.When construction, entire jacket frame foundation structure is transported to sea by cargo ship and is applied
Work scene, plays base position using crane ship tune, suction tube is sunk down into designed elevation by the way of vacuumizing, due to more
A suction tube is easy to appear the non-uniform situation of sedimentation in sinking watching, can generate stress, in the process, rubber washer 4
Meeting extrusion, conduit leg 22 can shake in taper connection cylinder 12, can reduce in suction tube sinking watching due to stress
Adverse effect of the unevenness to jacket.After equal suction tubes sink down into designed elevation, then to conduit leg 22 and taper connection cylinder 12 it
Between the annular space that is formed carry out underwater grouting mortar 5 and connect, made to be formed one between conduit leg 22 and taper connection cylinder 12 just
Property it is whole.
The above content is only to illustrate the technical solution of the utility model, and those skilled in the art are practical new to this
The simple modification or equivalent replacement that the technical solution of type carries out, all without departing from the essence and model of technical solutions of the utility model
It encloses.
