Description
Technical field
The present invention relates to a kind of fan foundation structure offshore construction method, more particularly to a kind of large-diameter pile blower foundation
Structure offshore construction method.
Background technology
Single-pile foundation structure has design simple, builds convenient, it is easy to construct, the advantages of reducing investment outlay.Therefore, current rank
Section offshore wind turbine foundation structural shape is mainly single-pile foundation structure.Along with the development of marine high-power blower unit and wind-powered electricity generation
The site depth of water increases, and large-diameter pile fan foundation structure diameter becomes big, and wall thickness increases, stake growth long, the weight of single pile structure
It is increasing, so as to marine transportation equipment and lifting ship equipment requirement more and more higher, ultimately result in existing construction equipment
The requirement of offshore construction can not have been met.
Due to construction ship shortage of resources, for the overweight single pile structure of major diameter also without suitable construction equipment, cause
Single-pile foundation structure can only be substituted from other types foundation structure form, accordingly increase the offshore construction time and invested into
This.So as to delay offshore construction speed, it is unfavorable for marine wind electric field construction.
The content of the invention
In order to solve the weak point existing for above-mentioned technology, the invention provides a kind of large-diameter pile blower foundation knot
Structure offshore construction method.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of large-diameter pile blower foundation knot
Structure offshore construction method, the equipment that construction method is used includes lifting ship and U-shaped transport barge；The equipment assembled on lifting ship
Including loop wheel machine, pile gripper and pile hammer, the equipment assembled on U-shaped transport barge include left fixing clasp, right fixing clasp and
Chute track；
Construction method is comprised the following steps that：
First, after assembling machine is in place, U-shaped transport barge transports single pile fan foundation structure to blower fan stake to lifting ship
Base position is cast anchor in place；Steel-pipe pile one end is lifted by crane using the hook of loop wheel machine；
Release the left fixing clasp on U-shaped transport barge；
Start loop wheel machine, single pile can rotate around right fixing clasp, realize that single pile is stood；
The relative position of steel-pipe pile and pile gripper on lifting ship is adjusted by chute track, realizes pile gripper to single pile structure
Constraint, piling construction is carried out finally by pile hammer.
The present invention is based on existing offshore lifting construction equipment, by the ships that transport of particular design, using relatively simple
The facility of easy processing manufacture, realizes marine transportation and lifting, the piling work of large diameter single pile foundation structure；Need not be from transport
Sling completely on barge single pile structure, by the snap ring on ships that transport realize the rotation of single pile structure and it is vertical stand, then
Fixed by lifting by crane pile gripper on ship, finally carry out piling work；Disclosure satisfy that the offshore lifting of marine large-diameter pile and apply
Work industry, meets the construction requirement of marine wind electric field.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of U-shaped transport barge.
Fig. 2 is lifting view.
Fig. 3 is the view that pile gripper fixes piling.
In figure：1st, ship is lifted by crane；2nd, U-shaped transport barge；11st, loop wheel machine；12nd, dress device is embraced；21st, left fixing clasp；22nd, right fixation
Snap ring；23rd, chute track.
Specific embodiment
As shown in Figure 1-Figure 3, equipment used in the present invention includes lifting ship 1 and U-shaped transport barge 2；Filled on lifting ship 1
Including loop wheel machine 11, pile gripper 12 and pile hammer etc., the equipment assembled on U-shaped transport barge 2 includes left fixing clasp to the equipment matched somebody with somebody
21st, right fixing clasp 22 and chute track 23 etc.；
Concrete construction method is：
After assembling machine is in place, U-shaped transport barge 2 transports single pile fan foundation structure to blower fan pile foundation to lifting ship 1
Cast anchor in place plinth position；Steel-pipe pile one end is lifted by crane using the hook of loop wheel machine 11, the left fixing clasp on U-shaped transport barge is released
21；Start loop wheel machine, single pile can rotate around right fixing clasp 22, realize that single pile is stood；Steel-pipe pile is adjusted by chute track 23
With the relative position of pile gripper 12 on lifting ship 1, realize that pile gripper 12, to single pile structural constraint, is beaten finally by pile hammer
Pile driving construction.
Can realize the offshore construction of overweight large diameter single pile foundation structure by above-mentioned arrangement and method for construction, the current stage sea apply
Work ship crane capacity is 800 tons or so, and single pile construction weight is increasing, and the development speed of construction ship does not catch up with construction
It is required that.Existing construction equipment can be made full use of using secondary this kind of arrangement and method for construction, and without lifting by crane single pile structure completely, in ship
Oceangoing ship crane capacity saves Potential Working Time For Operation At Sea less than single pile construction is completed in the case of single-pile foundation weight, improves operation on the sea
Security.
Above-mentioned implementation method is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
Change, remodeling, addition or replacement that the technical staff in domain is made in the range of technical scheme, also belong to this hair
Bright protection domain.
