Abstract
The invention discloses an offshore construction method for a large-diameter single pile fan foundation structure. A device used in the construction method comprises a crane ship and a U-shaped transportation pontoon. Devices assembled on the crane ship comprise a crane, a pile gripper and a pile hammer. Devices assembled on the U-shaped transportation pontoon comprise a left fixed clamping ring, a right fixed clamping ring and a sliding groove rail. The construction method includes the specific steps that firstly, after a fan installation machine of the crane ship is in place, the U-shaped transportation pontoon transports a single pile fan foundation structure to a fan pile foundation position, and an anchor is dropped in place; one end of a steel tube pile is hoisted through an upper lifting hook of the crane; the crane is started, and the single pile can rotate around the right fixed clamping ring so that the single pile can be erected; the position of the steel tube pile and the position of the pile gripper on the crane ship are adjusted through the sliding groove rail, the single pile structure is constrained through the pile gripper, and finally piling construction is carried out through the pile hammer. The offshore construction method can meet the requirement for offshore hoisting and construction of offshore large-diameter single piles, and the construction requirements of an offshore wind power plant are met.
Description
Technical field
The present invention relates to a kind of fan foundation structure offshore construction method, particularly relate to a kind of large-diameter pile fan foundation structure offshore construction method.
Background technology
Single-pile foundation structure has simplicity of design, and it is convenient to build, and is easy to construction, the advantage such as to reduce investment outlay.Therefore, offshore wind turbine foundation structural shape is mainly single-pile foundation structure the current stage.Increase along with marine high-power blower unit development and the wind-powered electricity generation site depth of water, large-diameter pile fan foundation structure diameter becomes large, wall thickness increases, the long growth of stake, the weight of single pile structure is increasing, thus to marine transportation equipment and lifting boats and ships equipment requirement more and more higher, finally cause existing construction equipment can not meet the requirement of offshore construction.
Due to construction ship shortage of resources, suitable construction equipment also be there is no for major diameter overweight single pile structure, cause selecting other types foundation structure form to substitute single-pile foundation structure, add offshore construction time and cost of investment accordingly.Thus delayed offshore construction speed, be unfavorable for marine wind electric field construction.
Summary of the invention
In order to solve the weak point existing for above-mentioned technology, the invention provides a kind of large-diameter pile fan foundation structure offshore construction method.
In order to solve above technical problem, the technical solution used in the present invention is: a kind of large-diameter pile fan foundation structure offshore construction method, and the equipment that construction method uses comprises lifting ship and U-shaped transport barge; The equipment that lifting ship assembles comprises loop wheel machine, pile gripper and pile hammer, and the equipment that U-shaped transport barge assembles comprises left fixing snap ring, right fixing snap ring and chute track;
The concrete steps of construction method are as follows:
First, lifting ship is after assembling machine is in place, and U-shaped transport barge transport single pile fan foundation structure casts anchor in place to blower fan pile foundation position; Use hook hoisting steel pile tube one end of loop wheel machine;
Snap ring is determined on a left side of removing on U-shaped transport barge;
Start loop wheel machine, single pile can be determined snap ring and rotate around the right side, realize single pile and stand;
By the position of chute rail adjustment steel pipe pile with pile gripper on lifting ship, realize pile gripper to single pile structural constraint, carry out piling construction finally by pile hammer.
The present invention is based on existing offshore lifting construction equipment, by the ships that transport of particular design, adopt and be comparatively simple and easy to the facility of processing and manufacturing, realize the marine transportation of large diameter single pile foundation structure and lifting, piling work; Without the need to single pile structure of slinging completely from transport barge, realize the rotation of single pile structure by the snap ring on ships that transport and vertically stand, then being fixed by pile gripper on lifting ship, finally carry out piling work; Offshore lifting and the construction operation of marine large-diameter pile can be met, meet the construction requirement of marine wind electric field.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
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: 1, lift by crane ship; 2, U-shaped transport barge; 11, loop wheel machine; 12, dress device is embraced; 21, snap ring is determined on a left side; 22, snap ring is determined on the right side; 23, chute track.
Detailed description of the invention
As shown in Figure 1-Figure 3, equipment used in the present invention comprises lifting ship 1 and U-shaped transport barge 2; On lifting ship 1, the equipment of assembling comprises loop wheel machine 11, pile gripper 12 and pile hammer etc., and on U-shaped transport barge 2, the equipment of assembling comprises left fixing snap ring 21, right fixing snap ring 22 and chute track 23 etc.;
Concrete construction method is:
Lifting ship 1 is after assembling machine is in place, and U-shaped transport barge 2 transports single pile fan foundation structure and casts anchor in place to blower fan pile foundation position; Use hook hoisting steel pile tube one end of loop wheel machine 11, snap ring 21 is determined on a left side of removing on U-shaped transport barge; Start loop wheel machine, single pile can be determined snap ring 22 and rotate around the right side, realize single pile and stand; Regulate steel pipe pile and the position of pile gripper 12 on lifting ship 1 by chute track 23, realize pile gripper 12 pairs of single pile structural constraints, carry out piling construction finally by pile hammer.
Can be realized the offshore construction of overweight large diameter single pile foundation structure by above-mentioned constructure scheme, current stage offshore construction boats and ships crane capacity is about 800 tons, and single pile construction weight is increasing, and the development speed of construction ship does not catch up with construction requirement.Adopt time this kind of constructure scheme can make full use of existing construction equipment, and single pile structure need not be lifted by crane completely, at boats and ships crane capacity lower than completing single pile construction when single-pile foundation weight, saving Potential Working Time For Operation At Sea, improving the safety of operation on the sea.
Above-mentioned embodiment is not limitation of the present invention; the present invention is also not limited in above-mentioned citing; the change that those skilled in the art make within the scope of technical scheme of the present invention, remodeling, interpolation or replacement, also all belong to protection scope of the present invention.
