Description
Technical field
The utility model relates to a kind of marine foundation structure of installing, particularly about a kind of pile foundation type foundation structure that is applicable to the various ocean engineerings of shallow water area.
Background technology
The ocean engineering of shallow water area especially offshore wind turbine foundation structure Design will be considered the influence of geological structure, offshore distance, sea turn, unrestrained load and ocean current, the ice etc. of sea bed, be divided into gravity, pile foundation type and bucket foundation formula etc. from form of structure, wherein be most widely used with pile foundation type foundation structure.Pile foundation type is divided into jacket-type and concrete bearing platform formula, and the concrete bearing platform formula generally is applied in the bridge pier structure, although cost is low, but because of its marine engineering amount big, cycle is long, can't overcome marine boisterous influence, is not therefore adopted by other offshore engineering structures.Jacket-type is widely used in the offshore engineering structure, be divided into several patterns such as three of only legs, three legs, four legs, it is the steel work prefabricated, the welding of carrying out steel work in land factory is prefabricated, arrive the installation site by barging, water under lifting of general employing crane barge or the slippage uses hydraulic pile hammer that piling bar is driven into the following projected depth of mud face, and connecting duct frame and piling bar at last are in the milk.The jacket-type supporting capacity is higher, and the depth of water scope of application is wider, but cost is very high, and spud leg is many, and the offshore construction cycle is still a bit long, for the compliance of marine harsh weather certain problem is arranged also.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides that a kind of cost is low, short construction period be applicable to the especially offshore wind turbine pile foundation type foundation structure of installing of ocean engineering.
For achieving the above object, the utility model is taked following technical scheme: a kind of pile foundation type foundation structure that is applicable to ocean engineering, it comprises an end stake of vertically squeezing in the mud face of seabed, it is characterized in that: an end that exposes the sea in the stake of the described end, be arranged with transition spool piece, be perfused with glue/slurry in the gap of described transition spool piece and end stake, be provided with radially shutoff in the bottom in described gap; Top in described transition spool piece is provided with equipment platform, and outer wall is provided with goes on board cat ladder and lean on ship spare, cable protecting tube and grouting pipeline.
The stake of the described end is a high strength steel pile tube, adopts sacrificial anode protection to carry out anticorrosion.
Described transition spool piece external surface has passed through the japanning preservative treatment.
Described transition spool piece and equipment platform are formed in one.
Described equipment platform is provided with the flange that is used to connect superstructure.
The utility model is owing to taked above technical scheme, it has the following advantages: 1, single pile foundation structure is to be the most frequently used, topmost foundation structure form in the domestic and international marine wind electric field construction, what the utility model provided is descending by stake of single end support, in last form of structure of being set for this platform by the grouting sleeve transition and linkage, reliable through facts have proved sound construction, and cost is low, economical rationality.2, single pile foundation structure operation is simple, and end stake can be prefabricated in precast yard, saves the offshore construction activity duration.At sea end stake is squeezed into the sea under fix after, again in the sheathed transition spool piece in pile body top, and by grouting sleeve pipe is fixed, because grouting is operation across the sea, so can adjust the verticality of sleeve pipe in the filling process at any time, thereby guarantee the levelness of sleeve pipe top equipment platform, for the equipment installation provides safeguard.3, the depth of water scope that is suitable for of single pile foundation structure of the present utility model is wide, goes for 0-30m depth of water scope according to a preliminary estimate, and it is big to promote development potentiality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, the utility model main body adopts a foundation stake to support, and therefore is referred to as the single pile basis.End stake 1 is a high-strength anti-corrosion steel pipe pile, during piling, and end stake 1 vertical entry, a part is inserted under the mud face fixing, and a part is exposed on the water surface.In the upper end of end stake 1, an end that promptly surfaces is arranged with a transition spool piece 2, is perfused with high strength cement mortar or epoxy mortar 3 in the gap of transition spool piece 2 and end stake 1, is provided with radially shutoff 4 in the bottom in gap.
In the foregoing description, the caliber of transition spool piece 2 can be bigger than end stake 1, transition spool piece 2 outer being enclosed within the end stake 1; The caliber of transition spool piece 2 also can be littler than end stake 1, in be enclosed within the end stake 1.
In the foregoing description, radially shutoff 4 can be an annular supporting plate of welding radially in the bottom of transition spool piece 2 or end stake 1, and annular supporting plate is filled up the gap between transition spool piece 2 bottoms and the end stake 1; Radially shutoff 4 also can be the mechanical packer that is provided with in the gap of transition spool piece 2 bottoms and end stake 1.
On the outer wall of transition spool piece 2, be fixed with the cat ladder of going on board, lean on ship spare and encapsulating/slurry pipeline 5, be connected with equipment platform 6 at the top of transition spool piece 2.The last plane of equipment platform 6 will remain level, and reaches certain required precision, in order to equipment such as installation blower fan tower barrels on equipment platform 6.Generally speaking, transition spool piece 2 and equipment platform 6 part that is formed in one is with the guaranteed strength requirement.Equipment platform 6 is a large-sized flange dish sometimes or flange is installed on platform.
Because transition spool piece 2 and top annex thereof directly contact with the sea, so the external surface of transition spool piece 2 need do preservative treatment, adopts the coating method anticorrosion usually.
The utility model is the assembled on site part, and it is integral prefabricated in land enforcement to be divided into 2 two parts of end stake 1 and transition spool piece, and uses ship to go to sea.Offshore construction must adopt self lift type to hang ship or ship is hung in seat end operation.When at sea constructing, at first make self lift type hang the ship emersion water surface or a seat end operation is hung at the bottom of the ship seat, guarantee that hull does not shake, with loop wheel machine end stake 1 is sling, and put into and hang on the ship default pile clamping device, vertically inserting in the mud and by deadweight and block back excision suspension hook by pile clamping device, the loop wheel machine hydraulic pile hammer of slinging is driven into design attitude under the mud face with end stake 1, carry out the verticality monitoring of end stake 1 in the injection process, guarantee that it is in scope of design.After treating that piling is finished, hang the ship transition spool piece 2 of slinging, be sleeved on end stake 1 top, implement leveling by default suspender, after reaching the design accuracy requirement, by encapsulating or cement mortar in the gap of encapsulating/slurry pipeline between end stake 1 and transition spool piece 2 of prepackage on the transition spool piece 2.Institute's encapsulating/slurry requires to solidify fast (being generally in 1-2 hour).Can extract suspension hook after solidifying fully.
