Abstract
The invention discloses a kind of marine steel pipe pile sinking construction technology, and it includes following job step：Measurement prepares, pile driving barge is in place, pile tube lifting, positioning pitching pile, fuller injection, checks absolute altitude, unloads hammer and pile frame displacement.Penetration power of the present invention is strong, efficiency of construction is high, vertical missing degree is small, can be applicable various rough seas, meet needed for engineering construction.
Description
Technical field
The present invention relates to ocean engineering construction technique field, and in particular to a kind of offshore steel
Pile tube sinking construction technology.
Background technology
Since 20 middle of century, the ocean offshore engineerings such as mobile semi-submerged platform, jack-up unit, oil and gas prospect production platform, seadrome and ton harbour are constantly risen, also more and more higher, particularly carrying foundation stone-steel pipe pile foundation are particularly important for requirement for engineering foundation construction.The distance that steel-pipe pile sinks to b.s.l. is deeper, directly subjects the heavy burden of superstructure and the etch of seawater, therefore the requirement to itself quality is relatively strict outer, and it is also to ensure the premise of construction quality to take rational pipe pile construction method or construction technology.
The content of the invention
It is applicable various rough seas it is an object of the invention to provide a kind of, meets marine steel pipe pile sinking construction technology needed for engineering construction.
In order to solve the above technical problems, the technical scheme is that：A kind of marine steel pipe pile sinking construction technology, it includes following job step：Measurement prepares, pile driving barge is in place, pile tube lifting, positioning pitching pile, fuller injection, checks absolute altitude, unloads hammer and pile frame displacement.
Further, the measurement preparation process includes surveying before sweeping sea, engineering and material prepares.
Further, pile driving barge step in place is driven into including stake ship, GPS location and cast anchor.
Further, the positioning pitching pile step carries out stake position-finding using ship as reference with laser ranging instrument on ship.
Further, in 30~35cm of stake top laying thickness sandalwood before the fuller injection.Beneficial effect：Penetration power of the present invention is strong, efficiency of construction is high, vertical missing degree is small, can be applicable various rough seas, meet needed for engineering construction.
Embodiment
In order to deepen the understanding of the present invention, the present invention is described in further detail with reference to embodiment.
Marine steel pipe pile sinking construction technology, it includes following job step：Measurement prepares, pile driving barge is in place, pile tube lifting, positioning pitching pile, fuller injection, checks absolute altitude, unloads hammer and pile frame displacement.
The measurement preparation process includes surveying before sweeping sea, engineering and the preparation of material.
The pile driving barge step in place is driven into including stake ship, GPS location and casts anchor.
The positioning pitching pile step carries out stake position-finding using ship as reference with laser ranging instrument on ship.
In 30~35cm of stake top laying thickness sandalwood before the fuller injection.
Specific implementation process
First, observing and controlling is carried out using total powerstation according to the stake point that owner provides, establishes this engineering construction Control coordinate system system, and report higher level's management department to check and accept accreditation.
2nd, it is dragged to according to the data that double-frequency GPS-RTK GPSs are shown on pile driving barge, pile driving barge by tugboat near stake point, the admiral anchor for being thrown into 6 10 tons of counterpoises carries out precise positioning.
3rd, pile transport ship approaching pile driving barge side, after two center line of boat are vertical, gantry stile on pile driving barge is tilted to the diameter center of the suspension hook alignment pile tube to be hung, put down after major-minor suspension hook is firmly linked with pile tube, main suspension hook rises, and secondary suspension hook declines, and is reached to a certain degree with rising to, secondary suspension hook solution is gone, and makes pile tube into erectility.
4th, hypsokinesis gantry stile, make pile tube and pile frame into after parallel shape, pile tube is embraced using pile gripper and is locked, in OPS pile frame gradient is adjusted by observing the angel measuring instrument on rangefinder and console on pile driving barge, stake is set to reach design attitude, main suspension hook is slowly put down, pile gripper is opened, makes pile tube automatically instrument under gravity.
5th, main suspension hook is released, in 30~35cm of stake top laying thickness sandalwood, first hammer tip-tap, with anti-slip stake, hammer force degree is progressively increased after injection is normal, in pile driving process, the change of stake position can be finely adjusted in the range of allowable error, abnormal if there is injection, and pile body inclining is excessive or during shifting phenomena, pile sinking should be stopped immediately, and reported to project supervision department and designing unit.
6th, pile tube stops hammering after reaching designed elevation, and carries out pile penetration check.
7th, unload and hammer and remove pile frame into shape.
