Referring to Fig. 10, the construction method on the jacket basis in an embodiment, comprising the following steps:
S100 provides suction bucket, and the first truss structure is built on suction bucket, to form marine pile.
Suction bucket can be and directly buy existing suction bucket, or build in build the side.First truss structure can be
It is vertically built on suction bucket.
S200 builds the second truss structure.
Step S100 can be carried out before step S200, alternatively, step S100 can be carried out after step S200, or
Person, step S100 and step S200 can be carried out simultaneously.Step S100 can be carried out from step S200 in different build the sides, with drop
The low requirement to build the side, so that existing build the side domestic at present be made to can satisfy the construction requirement on jacket basis.
Certainly, step S100 and step S200 can also successively be carried out in same build the side.In the present embodiment, when construction, marine pile
It needs vertically to build and general assembly, the second truss structure can select vertical or horizontal direction to build according to build the side and construction ability
It makes.
S300 respectively transports marine pile and the second truss structure to engineering sea area.Distinguished using different ships that transports
Marine pile and the second truss structure are transported to engineering sea area, to reduce the requirement to the transport capacity of ships that transport, to make
Domestic existing ships that transport can satisfy the transport requirement on jacket basis at present.It is of course also possible to utilize same cargo ship
Oceangoing ship successively transports marine pile and the second truss structure.In the present embodiment, marine pile is using vertical transport.Second truss structure can
According to the arc manipulation part out of the performance of ships that transport and build the side, vertical transport or horizontal direction transport are selected.
S400 lifts by crane marine pile, marine pile is made to sink.Specifically, hoist cable is connect with the first lifting lug, so that under marine pile
It is heavy.During marine pile is sunk, seawater injects in the outer tube between plugging plate and bearing partition via water injection pipe, in order to set
It is placed in marine pile sinking.When suction bucket is sunk down near sea bed, the intracavitary seawater of bucket is discharged in draining pump, passes through side bucket wall gradually
Enter fixed in sea bed.
S500 lifts by crane the second truss structure, is inserted in interior bar in grouting chamber.In the second truss structure sinking watching,
Valve is opened, seawater injects in hollow cavity via water inlet pipe, so as to the sinking of the second truss structure.Second truss structure sinks, with
Interior bar is set to be inserted in grouting chamber.After interior bar is inserted in grouting chamber, valve is closed, on the one hand prevents seawater from continuing to inject
In hollow cavity, the cavity wall of hollow cavity is on the other hand prevented to be corroded.
Marine pile is successively lifted by crane with the second truss structure, to reduce the requirement of the crane capacity to lifting ship, to make
Existing lifting ship domestic at present can satisfy the lifting requirement on jacket basis.
S600 makes interior bar and outer tube be in the milk and connects.Interior bar and outer tube grouting connect, and connect marine pile and the second truss structure
At an entirety, in order to which blower is arranged on the second truss structure.In the present embodiment, 28d compression strength is greater than
The high-intensitive grouting material of 120MPa pours into grouting chamber, until overflowing from grouting chamber.After grouting, water injection pipe is equal with water inlet pipe
It is blocked by grouting material.
Figure 11 is please referred to, the construction method on the jacket basis in another embodiment, with the jacket base in the present embodiment
The main distinction of the construction method of plinth is:
Further include step S410 after step S400, setting of the leveling ring in interior bar is adjusted according to the elevation of supporting element
Position.By measuring the elevation of supporting element, it can determine whether marine pile tilts.If marine pile does not tilt, ring is leveled
It is horizontally placed in interior bar；If marine pile tilts, level ring also and should be obliquely installed in interior bar, to guarantee the vertical of blower
Axis is vertical.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
