Description
Technical field:
The utility model is related to field of ocean engineering, more particularly, to a kind of marine large diameter pile with ice resistant structure
Basis.
Background technology:
China's Liaodong Wan, Bohai Sea Gulf and Laizhou Wan freezed in winter, ice condition is different according to the depth of water and offshore distance.Far
Bank profundal zone is floating ice, and offshore phytal zone is coast ice, and then can form hummocked ice in pole shallow sea, intertidal zone and beach area(Ice
Ridge).Liaohe ice condition is heavier, and 50 year return period, fixing ice thickness was 50cm, and floating ice maximal rate is 1.0 ~ 1.1m/s.The Liao Dynasty
Eastern gulf on January 11st, 2010 floating ice maximum border line once reached 131km, and individual layer sea ice thickness is more than 30cm.2010, claimed
For Yingkou situ Piles in Rock Filled Stratum in Bayuquan in the most northern ice-free port of China, local sea ice is the thickest to reach 1m, and the thickest ice sheet of Dalinghe River mouth reaches 1m, little Ling
River mouth offshore ice sheet average thickness is 30 ~ 50cm, and ice sheet doubles than past annual.
Marine structure(As marine large fan engineering, ocean platform)Mostly adopt large-diameter pile foundation.In high latitude
Marine site, sea ice is a greatly threat to marine large-diameter pile foundation.Two, Cook Inlet simple platform is pushed over by ice within 1963;
" Hai Erjing " drilling platforms collapses under huge sea ice thrust within 1969;The beacon tower of 1977 " Hai Sijing " is also extra large
Ice pushes over;The Central-South platform of JZ20-2 in 2000 occurs natural gas leaking to be forced to stop production under sea ice effect.2010, it is located at
The huge port tidal zone oilfield sea area ice condition in Bohai Sea Gulf is serious, and Offshore Units and platform are besieged by ice, and the offshore wellhead of 9 mouthfuls of wells is in heavy ice
Push lower disappearance.It can be seen that, the marine large-diameter pile foundation being threatened by sea ice needs protecting of ice resistant device.
Generally, the ice resistant structure of pile foundation is designed as a pyramidal structure, for large diameter pile, according to taper knot
Due to being relatively large in diameter, structure, causes that centrum volume is big, quantities is larger, constructional difficulties.

Specific embodiment:
Referring to accompanying drawing:
There is the marine large-diameter pile foundation of ice resistant structure, symmetrically, equably welded by a number of anti-ice standard component 1
Form around steel pile foundation.The anti-ice standard component being welded on around steel pile foundation be provided with each other main stiffened panel 7 with
Upper and lower two passage stiffened panels 8, to improve the lateral rigidity of anti-ice standard component.Anti-ice standard component 1 is evenly distributed in pile foundation week
Enclose, axisymmetricly state, and open ice blade 2 radially outward, thus forming ice resistant structure.
Anti-ice standard component 1 is structure symmetrical above and below, and outside symmetrically sets the arc that twice concave and opens ice blade 2, ice-cutter
Sword 2 be in cutting edge shape, when sea ice with open ice blade 2 contact action when, because the area that contacts with each other is less, on contact surface produce stress
Concentration makes sea ice easily disrumpent feelings, thus improving the effect that opens ice.
On anti-ice standard component 1, symmetrically arranged two blades 2 that open ice are in the arc shape that concaves, oblique with traditional conical surface
Face is compared, and the contact area (normally only rear and front end contact) when sea ice slides on arcwall face is less, easily produces stress collection
In and disrumpent feelings;
The two ends of anti-ice standard component 1 are symmetrically arranged gear ice male member 3, so that sea ice is slided on arc opens ice blade 2, fracture
Afterwards, from gear ice male member 3 at upset, come off, make sea ice cannot directly contact, damage large diameter pile 6.
Two triangle holes 4 are symmetrical arranged on anti-ice standard component 1, so that overall steel using amount is reduced;Anti-ice standard component is mutual
Between be provided with main stiffened panel 7 and two passage stiffened panels 8, integral rigidity is big.
Main stiffened panel 7 is welded at the axle symmetrical above and below of anti-ice standard component 1 adjacent two-by-two, its not with large diameter pile 6 phase
Mutually contact, anti-ice standard component is played with the effect of cross-brace.
Secondary stiffened panel 8 is symmetrically welded on the outside of the triangle hole 4 of anti-ice standard component 1 adjacent two-by-two, its with big
Diameter stake 6 is also welded to each other connection.
Anti-ice standard component 1 is evenly distributed in around pile foundation, makes sea ice when any direction acts on large diameter pile 6,
Typically there are 1 ~ 3 anti-ice standard component and sea ice front face, anti-ice effect is good.
The height of anti-ice standard component 1 is determined with low tide according to the high tide level intending fender pile place marine site.
Preferably, the top of anti-ice standard component 1 keeps off the high tide level that ice male member 3 is in large diameter pile 6, anti-ice standard component 1
Bottom keeps off the low tide that ice male member 3 is in large diameter pile 6, should be flat in large diameter pile 6 at the axle symmetrical above and below of anti-ice standard component 1
All tidal level.
Preferably, the crosspoint (i.e. peak) of two blades 2 that open ice and gear ice male member 3 minimum point on anti-ice standard component 1
Line and plumb line angle between 20 ° ~ 60 °.
Preferably, symmetrical around large diameter pile 6, equably welding anti-ice standard component 1 quantity is between 12 ~ 24.Stake footpath
Get the small value when less, stake footpath takes large values when larger.
Connection between anti-ice standard component 1, main stiffened panel 7, secondary stiffened panel 8, large diameter pile 6 is all using welding manner.
Particular location on large diameter pile 6 for the anti-ice standard component 1, by the embedded depth of stake, sea water advanced, high tide level, low
The parameters such as tidal level determine jointly.
After anti-ice standard component 1 is welded on large diameter pile 6 surrounding formation ice resistant structure, it no affects on the construction of pile foundation;
Because ice resistant structure has cutting edge, should wrap up during pile foundation construction, protect cutting edge, prevent its collision deformation.
The utility model compared with prior art, has the advantage that:The blade that opens ice on anti-ice standard component, makes sea ice produce
Raw stress concentration is easily disrumpent feelings, and the effect that opens ice is good;The blade that opens ice is in the arc shape that concaves, and is also beneficial to the disrumpent feelings of sea ice;Gear ice
Male member forces sea ice upset, comes off, and makes sea ice cannot contact pile foundation;Anti-ice steel for standard part amount is few, weld main stiffened panel with
After secondary stiffened panel, integral rigidity is big;Anti-ice standard component is axisymmetricly distributed around pile foundation, can resist the sea ice of any direction
Effect.
The utility model is not limited to above-mentioned specific embodiment, according to the above, according to the ordinary skill of this area
Knowledge and customary means, under the premise of without departing from the utility model above-mentioned basic fundamental thought, the utility model can also be made
The equivalent modifications of other various ways, replacement or change, all fall within protection domain of the present utility model.
