Abstract
The invention discloses a kind of spud leg pile extension under water technique for broken stone pile offshore engineering platform, by control and the grasp of tidal fluctuations to platform, two merging precisions of spud leg are determined according to spud leg latch centerline hole.The present invention solves the problems, such as that hypervelocity cannot be closed up on building berth, that is, meet final required precision, also shortens the production cycle, has saved production cost.
Description
Technical field
The present invention relates to a kind of pile extension under water technique, specifically a kind of spud leg water for broken stone pile offshore engineering platform
Lower pile extension technology, belongs to shipbuilding processing technique field.
Background technology
The structure type of pile legs of self-elevating drilling platform is triangle, truss transmission pattern, and weight is all at 150 tons -220 tons
Between.The liter ship pile extension technology of existing pile legs of self-elevating drilling platform segmentation is that the stake in outfitting quay will be transported to ocean crane ship
Leg segmentation is stood up, then in the sliding guide rail frock being lifted on self-elevating drilling platform deck with ocean crane ship, then adopt
Pile extension technology method is slid with the straight line for a liter ship → slide → position → close up.The method has following shortcoming：1st, building expense
With higher, 2 are influenceed larger by natural cause, 3, spud leg folding when safety coefficient it is low.
The content of the invention
The technical problems to be solved by the invention are the shortcomings for overcoming prior art, there is provided one kind is used for broken stone pile ocean
The spud leg pile extension under water technique of operation platform, solves the problems, such as that hypervelocity cannot be closed up on building berth, that is, meet final
Required precision, also shortens the production cycle, has saved production cost.
In order to solve the above technical problems, the present invention provides a kind of spud leg for broken stone pile offshore engineering platform connecing under water
Stake technique, comprises the following steps：
(1) the spud leg of separate unit tower crane erect：In tower crane lifting coverage, the softer place of geology, ground soft object is by stake
Leg pad is good, and spud leg is kept flat on the ground, and the suspension ring installed installed in spud leg top are hooked by the suspension hook of tower crane, slowly lifts by crane
Spud leg is erect；
(2) the influence that tower crane operator is risen/fallen to ship height by tidewater, so the length to tower crane steel wire rope influence, see
The change of loop wheel machine lifting weight data table is examined, the hook of tower crane is operated when less than actual weight, when more than actual weight
When operation tower crane suspension hook decline；
(3) the ship that control is swum on the water surface is in relative plateau, is absorbed water according to corner, takes ballast tank of ship ballast
Ship is adjusted to level by the mode of water, and hawser is fixed on harbour checking bollard；
(4) when constructing, before 1# spud legs are lifted, change is brought to ship center of gravity according to the spud leg weight center of gravity for being lifted, taken
The corresponding ballast water of injection in the ballast tank of diagonal storage spud leg；Similarly, ballast tank when lifting 2# spud legs in the storage of 3# spud legs is noted
Enter corresponding ballast water；During lifting 3# spud legs, now need the water in ballast tank at 2# spud legs to extract corresponding amount out, lift 4# spud legs
When, the water in the ballast tank of 1# spud legs storeroom need to be extracted out corresponding amount；Ship is in horizontal after keeping a piece leg of lifting
State；
(5) spud leg on ship declines, and 5-6 meter of fixed pile chamber deck is only stretched out in spud leg end, i.e., 3 length of pin hole, when needing to lift
Spud leg placing flat on the ground when, find out laterally adjacent latch centerline hole, and carry out mark, from top from top to down,
Steel wire is drawn to easy to remember point, the center line of upper end spud leg is aligned with bottom spud leg latch centerline hole, you can according to center
Line completes alignment pile extension.
Further, the spud leg pile extension under water technique of broken stone pile offshore engineering platform, the soft object are previously described for
It is rubber tyre.
The beneficial effects of the invention are as follows：Present invention eliminates the use of ocean crane ship, by environment and inside even from weather
Small, job area is small, and lifting operation is more steady, improves safety coefficient during spud leg folding, greatly save the engineering time and
Construction cost, the scale requirements that the outfitting quay and basin moored is stayed to platform are low, it is ensured that spud leg turns to the suitable of sliding pile extension technology
Profit is implemented.Solve the problems, such as that hypervelocity cannot be closed up on building berth, that is, meet final required precision, also shorten production
In the cycle, production cost is saved.
Specific embodiment
Embodiment 1
