Abstract

The utility model discloses a kind of taper Blade fence, comprising steel drum, steel discharge ring, gutter, crab-bolt, it is characterized in that: steel drum lower open end diameter is slightly larger than upper closed end, steel drum sidewall symmetry welds two also can be used to mooring floating structure crab-bolt for lifting steel drum, steel drum upper weld has the steel discharge ring for connecting superstructure, steel drum top discharge ring bilateral symmetry arranges two drain holes, drain hole is installed the gutter with switch.The utility model basic infrastructure openend diameter is slightly larger than upper closed end, the structure that this foundation side wall tilts can increase the passive earth pressure that basis produces inside and outside bucket when being subjected to displacement, add the lifting surface area on basis during basic bearing load, improve the frictional force of foundation side wall and ground, effectively enhance barrel base supporting capacity.

Description

A kind of taper Blade fence
Technical field
The utility model relates to ocean platform and offshore wind turbine foundation, is specially a kind of taper Blade fence.
Background technology
Along with the increase day by day of marine resources development demand, the development of ocean wind power engineering, ocean engineering construction also gets prosperous with every passing day, and barrel base just arises at the historic moment, and is a kind of Novel ocean platform architecture basics pattern.Barrel base compensate for the deficiency increased considerably with the depth of water from great, construction costs of the shallow sea offshore engineering structures such as traditional pile supported platform and gravity platform, there is low, the reusable advantage of cost, the ocean engineering field such as be now applied to offshore wind power foundation gradually, ocean platform builds, floating marine structure is fixing.Because ocean platform and offshore wind farm pylon bear huge superstructure deadweight and the effect of wind load and wave force, significant consideration when therefore Vertical Load and horizontal loading are ocean engineering working designs.
When being subject to uplift load, uplift load is resisted mainly through staving own wt and the frictional force between bucket wall and the interior outside soil body in conventional barrel basis, and when basis is subject to uplift load straight up, basis is easily pulled out, and causes base integral to destroy.When being subject to horizontal loading, the horizontal loading of superstructure generation is offset mainly through the basis passive earth pressure that horizontal force side produces dorsad in conventional barrel basis, it produces the side that drag position is mainly basic top horizontal force dorsad, the passive earth pressure produced is less, even loses efficacy in basis easily run-off the straight.Therefore, in order to improve the supporting capacity of suction barrel base, promoting the exploitation of marine energy sources resource, needing to propose the higher novel barrel base of a kind of supporting capacity.
Summary of the invention
In order to solve barrel base by producing vertical displacement and horizontal movement and the problem causing basis to be lost efficacy that rotates when vertical load and horizontal loading, the utility model provides a kind of taper Blade fence, the passive earth pressure that this basis produces inside and outside bucket when being subjected to displacement by increasing basis, add the lifting surface area on basis during basic bearing load, improve the frictional force of foundation side wall and ground, effectively enhance barrel base supporting capacity.
For achieving the above object, the utility model discloses a kind of taper Blade fence, comprising steel drum, steel discharge ring, gutter, crab-bolt.It is characterized in that: steel drum lower open end diameter is slightly larger than upper closed end, steel drum sidewall symmetry welds two also can be used to mooring floating structure crab-bolt for lifting steel drum, steel drum upper weld has the steel discharge ring for connecting superstructure, steel drum top discharge ring bilateral symmetry arranges two drain holes, drain hole is installed the gutter with switch.
The beneficial effects of the utility model are:
(1) taper suction type foundation lower open end diameter is slightly larger than upper closed end, and the structure that this foundation side wall tilts can increase the passive earth pressure that basis produces inside and outside bucket when being subjected to displacement;
(2) taper Blade fence can make full use of the soil pressure of the barrel base side wall upper part soil body and basis and the frictional force of the soil body, based on the ability of opposing uplift load is provided;
(3) increase bucket base bearing surface area when load is straight down born on basis, meanwhile, because bucket wall is low wide and up narrow, when there is vertical displacement, the compactness of the basic internal soil body significantly improves, and improves the ability that load is straight down resisted on basis;
(4) increase basis and produces the contact area in passive earth pressure region with ground, reduce the horizontal movement and rotation displacement that produce when horizontal loading is born on basis, effectively improve the ability that barrel base resists horizontal loading.
Accompanying drawing explanation
Fig. 1 is the sectional drawing of a kind of taper Blade fence of the utility model;
Fig. 2 is the top view of a kind of taper Blade fence of the utility model;
Marginal data: 1-steel discharge ring; 2-gutter; 3-steel drum; 4-crab-bolt.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
As shown in Figure 1, a kind of taper Blade fence, comprising steel drum 3, steel discharge ring 1, gutter 2, crab-bolt 4.It is characterized in that: steel drum 3 lower open end diameter is slightly larger than upper closed end, steel drum 3 sidewall symmetry welds two also can be used to mooring floating structure crab-bolt 4 for lifting steel drum 3, steel drum 3 upper weld has the steel discharge ring 1 for connecting superstructure, steel drum 3 top discharge ring 1 bilateral symmetry arranges two drain holes, drain hole is installed the gutter 2 with switch.
Detailed description of the invention of the present utility model is: taper Blade fence is heavy pass through installation before, first flatten seabed foundations plane, barrel base is lifted again by crab-bolt 4, barrel base is placed in heavy position of passing through according to basis, first utilize barrel base to conduct oneself with dignity and carry out heavy passing through, when barrel base no longer declines under Gravitative Loads, recycling suction pump connects gutter, drawn water by gutter 2 pairs of basic internal, steel drum 3 inside water pressure is declined, pressure differential is produced with steel drum 3 outside, namely suction penetration is carried out to basis, namely the construction of novel foundation is completed to steel drum 3 end face and sea bed either flush.
