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.
Floating body guide pile in the present embodiment can be used for beacon, buoy, drilling platforms, exploration, dredger, marine ship code
The positioning and fixing of the marine structures such as head, the harbor, man-made island construction, the quantity of floating body guide pile can also be according to actual needs
It is configured.But it is not limited only to above-mentioned application.
To sum up, the inline pass of the floating body guide pile in the present embodiment is subject in ocean using pile body buoyancy and gravity
System, realizes the effect and purpose of positioning and fixing of the pile body in ocean, and floating body guide pile can be realized without locking bolt and fix not
