In the embodiment shown in fig. 4, each of first resistance piece 111 extends to another from one end of connecting column 110 End, it is identical as connection column length.Wherein, each point of the first resistance piece 111 can be located on same axial plane, can also position In in axially different plane, i.e., the first resistance piece 111 can be planar, be also possible to curved, wherein preferably planar.
In some embodiments, it is equipped in the axial external surface of connecting column 110, between adjacent two first resistance piece 111 Multiple second resistance pieces 112, for increasing seawater to the resistance of connecting column, specifically, being to increase seawater to moving down on pile body Resistance when dynamic.Multiple second resistance pieces 112 are arranged along the prolonging direction interval of connecting column 110, multiple second resistance pieces 112 Each of be fixedly connected with connecting column 110 and adjacent two first resistance piece 111, each of multiple second resistance pieces 112 with The axial external surface of connecting column 110 is in the nonparallel angle of cut, each of multiple second resistance pieces 112 and the first resistance piece 111 In the nonparallel angle of cut.Second resistance piece can be plate-like, and the plate face of the second resistance piece 112 can be perpendicular to the axial direction of connecting column Outer surface.If the first resistance piece 111 and the second resistance piece 112 are plate-like, the plate face of the second resistance piece is perpendicular to the first resistance The plate face of part.
Wherein, each point of the second resistance piece 112 can be located on same sagittal plane, and it is flat can also to be located at different radial directions On face, i.e., the second resistance piece 112 can be planar, be also possible to curved, wherein preferably planar.
The setting of first resistance piece 111 and the second resistance piece 112 can need to carry out according to the intensity of pile body.In some realities It applies in example, the first resistance piece 111 can be set 4, and the circumferential direction along connecting column 110 is uniformly distributed, and every two adjacent At interval of 4.75 meters of settings, one the second resistance piece 112 between first resistance piece 111, along 110 prolonging direction of connecting column.
It, can also be in connecting column 110 when such as preceding floating body guide pile has deposit cabin 150 and 160 structure of truss The first resistance piece 111 of upper setting and the second resistance piece 112, this will not be detailed here.
As before, it can be steel construction that ocean positioning 100 is whole.In some other embodiment, ocean positioning 100 is whole It can be reinforced concrete structure, it may be assumed that connecting column 110, buoyancy compartment 120 and ballast tank 130 are reinforced concrete structure, this The technique of kind material is more mature and manufacture difficulty is lower, and pile body overall structure size can be bigger at this time, such as buoyancy The total displacement in cabin 120 can be greater than 5000t (1t=1000Kg).
With continued reference to Fig. 5, in some embodiments, when floating body guide pile is reinforced concrete structure, since connecting column 110 is horizontal It is larger to size, channel 140 can also be set, and channel 140 is located in connecting column 110 and extends along connecting column 110, through connection Column 110 and buoyancy compartment 120, channel 140 is for loading ballast, when floating body guide pile works in the seawater, channel 140 One end on sea is connected to 140 ambient atmospheres, one end of the immersion seawater in channel 110 is connected to seawater, channel 140 and buoyancy Cabin gas is not connected to.
Since the lateral dimension of the floating body guide pile of reinforced concrete structure can be relatively large, the size in channel 140 It can also be larger.For example the diameter in channel 140 can be 10m and be formed in connecting column 110 that the lower end in channel 140 is for filling out Pressurising loading increases the quality of pile body, can serve as the effect of ballast tank, thus in the shorter situation of 110 length of connecting column, It can guarantee the quality of entire floating body guide pile and keep the center of gravity G of floating body guide pile lower, increase centre of buoyancy away from (i.e. center of gravity G and floating The distance between heart M) so that floating body guide pile is stable in the seawater.Ballast can be stone, the biggish object of iron block isodensity Matter, it is contemplated that iron block is easy by seawater corrosion, and stone is preferable.
Bottom wall (not shown) can also be set on one end of the immersion seawater in channel 140, through-hole can be set on bottom wall, led to Hole is for allowing channel 140 to be connected to seawater.
For the floating body guide pile of reinforced concrete structure, can complete to build by cast in situs across the sea.
The working principle of the floating body guide pile of the embodiment of the present invention is as follows, with continued reference to Fig. 1, when floating body guide pile is not by cross Outward force (is parallel to the active force in the direction of sea level S, such as the power applied by wind or wave, the movement of ocean current is very Slowly, can be ignored for the power that floating body guide pile applies is relative to wind-force) effect when, perpendicular to sea level S, In original state;When being acted on by lateral external forces, lateral external forces will generate heeling moment, according to Ship Statics, floating body The gravity of guide pile itself will generate righting moment;In addition, pile body is in underwater part also by hydraulic pressure (pressure of seawater) Effect, hydraulic pressure will generate resistance torque.Righting moment and resistance torque can resist heeling moment, promote floating body guide pile Return back to reset condition.
By taking the floating body guide pile of reinforced concrete structure as an example, lower surface analysis under the action of the wind, floating body guide pile by Power situation.Referring to Fig.1, wind-force acts on into floating body guide pile the part for being exposed to sea level S or more, defines in wind-force effect The heart is wind-force center P.
When only considering wind-force effect, it is assumed that floating body guide pile tilts 0.1 ° (angle), by wind-force, gravity and seawater The active force of three aspect of pressure (seawater pressure for only considering centre of buoyancy to bottom part here), specific force analysis are as follows:
Defining distance of the wind-force center P apart from centre of buoyancy M is H1, distance of the center of gravity G apart from centre of buoyancy M is H2, hydraulic pressure be (seawater Pressure) centre distance centre of buoyancy M distance be H3, definition wind-force is FP, buoyancy FM, gravity FG
In some embodiments, buoyancy compartment 120, connecting column 110 are disposed as the cylinder that cross section is square, wherein floating Power cabin 120 is that cross-sectional width is 40m, is highly 10m, and the cross-sectional width of connecting column 110 is 10 meters, and a height of 40 meters, floating body positions The distance of stake bottom end b to top a is 50m, and gross mass may be configured as 8000t up to 6610t, the displacement of buoyancy compartment 120.
By calculating, when unloaded, floating body guide pile draft is about 44m, and buoyancy compartment 120 is exposed to sea level S or more Height be about 6m, wind area B=240m2, height of the center of gravity G apart from bottom end b is about 29m, height of the centre of buoyancy M apart from bottom end b Degree is about 42m, and the height of hydraulic pressure center to bottom end b is 14.7m;Then H1=5m, H2=13m, H3=27.3m.The above numerical value is Approximation.
Assuming that under the action of the wind, 0.1 degree of floating body guide pile tilt angle, then force analysis is as follows:
The heeling moment T that wind-force generatespAbout are as follows:
Tp=FP·BC·H1
The righting moment T that gravity generatesGAbout are as follows:
TG=FG·H2·Sin0.1°
The torque that hydraulic pressure generates is defined as TW, as a simplification example, the resistance torque T of waterWFollowing formula can be used It calculates:
TW=ρ VTH3
Wherein ρ is density of sea water, and V is the volume for the water pushed open when entire pile body tilts (it is contemplated herein that centre of buoyancy M is extremely in pile body The volume for the water that the part bottom end b arranges), H3For the distance of hydraulic pressure center to centre of buoyancy M, T is hydraulic pressure coefficient (when the floating body of 50 meters of depths When guide pile is fully immersed in seawater, suffered average water pressure is equivalent to 2.5 atmospheric pressure, i.e. hydraulic pressure coefficient is 2.5.Here Take T=2).
When only considering gravity, when floating body guide pile tilts 0.1 degree, it should at least meet Tp=TG, it may be assumed that
FP·BC·H1=FG·H2Sin0.1 ° (formula one)
Wherein B is wind area, and C is coefficient of streamline shape (C=0.5).
In formula one, C can be saved in order to increase safety coefficient.
Above-mentioned parameter is substituted into formula one, then obtains FP≈0.25t/m2
When only considering hydraulic pressure, when floating body guide pile tilts 0.1 degree, it should at least meet Tp=TW,
FP·BC·H1=ρ VTH3(formula two)
Each parameter is substituted into above-mentioned formula two, then obtains Fp=1.5t/m2
When comprehensively considering gravity and hydraulic pressure, in the present embodiment, if floating body guide pile tilts 0.1 degree, the wind-force needed At least FP=1.75t/m2.Inclined angle is bigger, then the wind-force needed is bigger.
Under normal circumstances, the wind-force maximum on sea is only capable of reaching 1t/m2, because people will be by when every square metre of arrival 1t It blows to and goes in the air, the wind pressure greater than every square metre of 1t is seldom.When pile body is used as buoy, since it is for steady Qualitative requirement is not strict (such as 1 degree of inclination also has no relations, as long as not being displaced), and above-mentioned pile body completely may be used To meet the requirements;When the stability requirement to pile body is stringenter, such as drilling platform, man-made island etc. It, then can be by increasing ballast into connecting column or increasing pile body length to increase the centre of buoyancy of pile body away from Huo Zhetong when positioning It crosses and adds the first, second flaps to increase in a manner of seawater resistance etc., to reinforce the stability of pile body.
In other embodiments, the gross mass of floating body guide pile can be that other values then should but if being bar construction 5000t should be not less than if it is reinforced concrete structure not less than 50t;If necessary to increase the load of floating body guide pile Amount and stability, then can by increase the total length of floating body guide pile, centre of buoyancy away from and increase its gross mass and buoyancy compartment Displacement is realized.For the floating body guide pile of steel construction, calculation method is similar, since the size of steel production is not too large, For its floating body guide pile with reinforced concrete structure in some differences of pile body, the connecting column of the floating body guide pile of steel construction may ratio It is relatively thin, in order to increase the total quality of floating body guide pile, the connecting column of the steel construction be made to it is long, such as can be with It is 350 meters, to increase quality, lower the center of gravity to improve stability.Floating body positioning pile material described above is steel or reinforcing bar Concrete can also be other materials, underline herein, should not cause to limit to the present invention in other embodiments.
