A kind of specific embodiment on offshore boosting station jacket basis as illustrated in fig. 1 and 2, including infrastructure, bottom
End is fixed in sea bed 4, and the part inside the infrastructure beyond sea level 3 is integrated with cable floor 1.
Above-mentioned offshore boosting station jacket basis can carry out each collection electric line and submitting after the completion of infrastructure construction
The Landing Construction of sea cable reduces the at sea activity duration of sea cable 6, to accelerate the progress of wind farm grid-connected power generation, simultaneously
The construction organization effect of Construction of Wind Power can be optimized from the processes such as blower foundation construction, blower lifting construction and submarine cable operation
Rate obtains better economic benefit.
Specifically, the infrastructure can be single-pile foundation containing changeover portion, underwater first stake method card edge type jacket
Stake method shoe formula jacket basis or rear stake method brace type jacket basis waterborne etc. after basic, underwater.As shown in Figure 1, lower part
The bottom on basis can be embedded in sea bed 4 by steel-pipe pile 9, to guarantee the firmness and reliability of construction.
As a kind of specific embodiment, above-mentioned cable floor 1 is located at the position inside the infrastructure close to top.
Specifically, the cable floor 1 is located on sea level 3, and absolute altitude need to meet the variation of period tidal level, limit wave height and air gap in place
Deng marine fixed platform related request.
Above-mentioned cable floor extends from the center of place plane to the direction far from the infrastructure, until beyond under described
Portion basis.I.e. the cross-sectional area of cable floor be greater than place plane respective lower basis cross-sectional area, to increase cable floor 1
Loaded area, it is convenient to lay other necessary devices at an upper portion thereof.
In order to further increase the anti-seismic performance and structure stress intensity of cable floor, extend in above-mentioned cable floor 1 described
The periphery lower part of infrastructure is provided with several supporting elements 7, and several supporting elements 7 are evenly distributed on the circumferential direction of infrastructure, described
The other end of supporting element 7 is fixed on the infrastructure.Specifically, above-mentioned supporting element 7 be both ends respectively with the cable floor 1
Lower surface and the infrastructure sidewall weld steel construction brace, welding can be previously-completed in factory, be applied with reducing
Work difficulty improves construction efficiency.Angle between above-mentioned brace and the cable floor 1 is 30-70 °.
Inside above-mentioned infrastructure, and it is located above the cable floor and is provided with construction supporting layer 2.The construction support
Layer 2 is embedded in inside the infrastructure.Construct the structure that supporting layer 2 can make infrastructure be located at 1 above section of cable floor
It is more stable.
Above-mentioned infrastructure is the jacket 8 being made of several steel pipes being welded to each other, and several steel pipes include several vertical
Steel pipe, several lateral steel pipes and the inclined tube for connecting vertical steel pipe and lateral steel pipe simultaneously, two neighboring inclined tube is arranged in a crossed manner,
To improve the integral firmness and stability of infrastructure.J-type pipe is provided between the two neighboring horizontally disposed steel pipe
5, and the top of the J-type pipe 5 is located in the cable floor 1.
Cable floor 1 can be anchored in by passing through after J-type pipe 5 logs in sea cable 6 in this way, at the same sea cable 6 itemize after leader cable and
Optical cable is capable of fixing in sea cable bracket 12, and being arranged in for sea cable bracket 12 meets the same of sea cable laying minimum bending radius requirement
When, also meet upper chunk lifting rear main sea cable in place and connect workload minimum with main transformer, GIS.
