State fixed guide pipe 6, and go deep into seabed first set depth.
The strand probing positioning system that the present embodiment provides combines pontoon positioning dress by using described sleeve pipe compensator
Put the combination application restricted in probing ore deposit in strand, ensure that pontoon located lateral under the conditions of stormy waves is steady by pontoon positioner
Fixed, vertically can both may be used by the sleeve pipe that casing expander realizes drilling tool two sections different-diameter with the vertical heave of tidewater fluctuation
Stretch with the free heave of tidewater fluctuation and can seal well again.In a word, the technical scheme structure that the present embodiment provides is simple, processing
Convenient, quick for installation, a large amount of while completing strand probing task can reduce engineering times and cost, realize benefit maximum
Change.
The operation principle of the technical scheme that the present embodiment provides is as follows：
Floating drilling barge located lateral and vertical heave：By being fixed on press-in seabed one in the fixed guide pipe outside hull
The steel-pipe pile of depthkeeping degree carries out to pontoon forcing horizontal, vertical positioning, ensures that floating drilling barge realizes transverse direction base under the conditions of stormy waves
This is not subjected to displacement, vertically can be with tidewater fluctuation vertical heave activity.Wherein, fixed guide Gutron is crossed clip to be fixed on probing floating
Outside the hull of ship.
The vertical heave of drilling tool：The sleeve pipe realizing two sections different-diameter by casing expander both can with tidewater fluctuation certainly
Stretched and good seal by heave.
Need exist for illustrate be：Described sleeve pipe compensator in the present embodiment two can directly adopt above-described embodiment one
The casing expander of middle offer, concrete implementation structure can be found in the corresponding contents in the various embodiments described above, and here is omitted.
Further, described pontoon positioner may also include：Pin.Wherein, described pin is arranged on described positioning steel
On pile tube, it is used for hitching rope.In the specific implementation, described pin may be provided at positioning steel tube stake top subordinate 100mm.I.e. steel
At 100mm under pile tube top, the eyelet of radial direction air exercise Φ 50mm, penetrates described pin, carries out in order to hitch steel wire rope connection jack
Pressurization, operational error positioning steel tube stake when being also prevented from installing slips in globigerina.
Further, the internal diameter 3～5mm bigger than the external diameter of described positioning steel tube stake of described fixed guide pipe.
Further, the first set depth is 2～5m.
Further, the length of described positioning steel tube stake is more than or equal to described floating drilling barge pimsoll line with upper hull
Height, the depth of water and described first set depth sum.
In specific embodiment, the choosing of the physical dimension of each part and setting quantity in the present embodiment pontoon positioner
Take specifically to adopt and realize with the following method：
Positioning steel tube stake should be according to regioselective steel-pipe piles such as the size of pontoon, water line, sea water tidal range, wave forces
Quantity, diameter, wall thickness, length.For example, after the flood tide of marine site water level in below 6m, pontoon platform gross weight 800-1000t, optional
With 6 Φ 168mm seamless steel pipes as positioning steel tube stake, positioning steel tube stake long more than 10m, wall thickness 12mm, grade of steel are more than No. 20.
The material of positioning steel tube stake, specification are checked from preferably carrying out correlation.The length computation of positioning steel tube stake refers to formula：Positioning steel
Length >=the pimsoll line of pile tube enters the 2 meters=10m in seabed with upper hull high 2m+ depth of water 6m+；Positioning steel tube stake bending resistance meter
Calculation refers to equation below：
The transverse horizontal active force to every positioning steel tube stake for the work area wave：
F=0.5 × (the sea water severe × smooth coefficient × mean wave height of gentle slope coefficient × ripple) × mean wave height × captain
÷ positioning steel tube stake radical
=0.5 × (10kN/m3 × 1.37 × 1.06 × 0.8m) × 0.8m × 20m ÷ 6=15.4kN/ root
Bending resistance checks：Transverse horizontal active force × mean depth≤positioning steel tube stake the bending resistance of every positioning steel tube stake of M=
Intensity
=15.4kN/ root × 5m=77kN M ＜ 86kN M
Pin：The eyelet of positioning steel tube stake top subordinate's 100mm outer radial air exercise Φ 50mm, penetrates pin, in order to hitch steel
Cord connects jack and is pressurizeed, and operational error positioning steel tube stake when being also prevented from installing slips in globigerina.
Fixed guide pipe：Every positioning steel tube stake is equipped with and one saves long 2m, wall thickness 10mm, internal diameter be more than steel-pipe pile external diameter 3～
The fixed guide pipe of 5mm.
Clip：2 sets of processing has the clip that some strength can clamp fixed sleeving, and clip is inside and outside hemizygous form.In block
Hoop is welded on hull, and welding is from the iron plate of thick 20mm.Outside collar is held tightly even with fixed guide pipe using the bolt more than M35
Connect.
The assembling flow path of the pontoon positioner that the present embodiment provides：
Step 201, clip in clip is welded on floating drilling barge.
Step 202, using bolt by outside collar and inner clamp connection, and by screwing described bolt by fixed guide Guan Gu
It is scheduled in described clip.
Step 203, positioning steel tube stake is lifted, and insert in fixed guide pipe.
Step 204, at the stake position determining, positioning steel tube stake is pressed into seabed first set depth.
Step 205, rise pull out positioning steel tube stake, pontoon form is displaced to next hole position.
Flow process is explained in detail：Determine the position of positioning steel tube stake in the both sides of pontoon, first inner clip be welded on floating drilling barge,
Respectively weld one in the vertical direction of pontoon water line and the side of a ship up and down, welding must be firm.Outside fixed sleeving after welding
Clip is clamped, and then with crane, positioning steel tube stake is hung and is inserted in fixed guide pipe, and positioning steel tube stake utilizes ordinary casing clamping plate
(joining two for every, fixing use of can substituting), height clamped on demand, processed choosing of high 2.5m near positioning steel tube stake aboard ship
Bar (is possible with the higher side of a ship), hangs 5t chain sling, pulls out positioning steel tube stake in order to be pressed into and to rise.
As shown in figure 4, drill the schematic flow sheet of localization method for the strand that this utility model embodiment three provides.This reality
The methods described applying example offer is the method realized based on the casing expander that the various embodiments described above provide.Wherein, described strand
Probing localization method, including：
Step 101, floating drilling barge positioning after the completion of, by lower end drilling seabed second set depth of first order sleeve pipe.
Wherein, described second set depth is the length more than 10m.
