Description
Technical field
The utility model relates to cushion cap blower foundation, particularly a kind of cushion cap anchoring type blower foundation.
Background technology
Wind energy turbine set basic engineering field at sea, when the depth of water is comparatively dark, complex geologic conditions time, the highrise pile cap blower foundation adopted is due to top employing cast-in-situ concrete cushion cap, foundation structure is comparatively thick and heavy, cushion cap stiffness by itself is larger, taper pile is to structure stress and resist horizontal movement advantageously, and compare other foundation pattern, cushion cap blower foundation is obviously dominant in structural shape, construction ability, construction costs etc.In intertidal belt wind electric field basic engineering field, because the depth of water is more shallow, seabed mostly is Muddy Bottoms, the impact of wet dilation ebb, during this marine site sea bed, expose sea, time and below the water surface.Construction ship limits by the depth of water construction of cannot marching into the arena, and the foundation pattern such as single pile, jacket is difficult to adopt, and the land blower foundation of routine is because of reasons in structure, and blower fan tower barrel is easily intake, foundation bed is washed.The low stake high important actor blower foundation scheme adopted is due to bottom employing PHC pile foundation, top adopts cast-in-situ concrete cushion cap and important actor, foundation structure is comparatively thick and heavy, cushion cap stiffness by itself is larger, compare other foundation pattern, the high important actor blower foundation of low stake is obviously dominant in structural shape, construction ability, construction costs etc.
Present stage, wind-power electricity generation acc power improved rapidly, and each blower fan manufacturer has all released one after another the blower fan model machine of 3MW, 5MW, 6MW, and more powerful blower fan is also in the middle of development.Along with the raising of power of fan, the load of blower fan is also doubled and redoubled.The blower fan tower barrel flange in the bottom diameter of the sharp wind-powered electricity generation 3MW110m of China is more than 5m, and the ultimate bending moment of tower cylinder base load reaches 160,000 kNm, and the ultimate bending moment of 5MW110m offshore fan tower barrel base load is close to 220,000 kNm.The increase of blower fan load, brings the increase of the blower foundation cushion cap scale of construction.
Existing blower foundation all to adopt in concrete bearing platform pre-embedded foundation ring to connect concrete bearing platform and concrete bearing platform top tower cylinder, for ensureing that discharge ring buried depth causes the structure stress of concrete bearing platform unreasonable, and a large amount of reinforcing bar must be configured and meet force request, reinforcing bar and concrete amount are large, blower foundation construction quality and programming low.
Summary of the invention
The purpose of this utility model is, not enough for prior art, provides a kind of cushion cap anchoring type blower foundation, and integral rigidity is large, saves reinforcing bar and concrete amount, makes blower foundation construction quality and programming all obtain larger raising.
The technical solution of the utility model is, a kind of cushion cap anchoring type blower foundation, comprise concrete bearing platform, concrete bearing platform bottom for support concrete bearing platform stake, for connecting the bindiny mechanism of concrete bearing platform and concrete bearing platform top tower cylinder, described bindiny mechanism comprises many groups and vertically embeds bolt assembly in concrete bearing platform, and all bolt assemblies are rounded centered by the vertical central axis of concrete bearing platform in concrete bearing platform is uniformly distributed.
Utilize bolt assembly to substitute discharge ring to realize tower cylinder and be connected with foundation platform, when blower foundation bears the eccentric bending moment transmitted from tower cylinder, tension side, blower foundation end face side pressurized.Bolt assembly is by pull transfer to foundation bed, and pressure is delivered to whole concrete bearing platform by basic end face concrete.Adopting the form of structure of bolt assembly, basic engineering buried depth can be made to change more flexible, the sacrificial structure receive strength rationality because adjusting embedded depth of foundation can not being caused as pre-embedded foundation ring, and a large amount of reinforcing bar must be configured meet force request.
The top of described stake embeds the inside of concrete bearing platform from the bottom surface of concrete bearing platform, described stake is symmetrical with the vertical central axis of concrete bearing platform, stake can select steel pipe pile, and stake can be and vertically arranges or be obliquely installed, and guarantees the stable support to concrete bearing platform.
The end anchoring ring that described bolt assembly comprises stone bolt, is located at the top anchoring ring of concrete bearing platform end face, is located at concrete bearing platform inside, the bottom of the pre-buried structure Transducers Embedded in Concrete cushion cap of described stone bolt, and the screw rod of stone bolt is through end anchoring ring and by fastening nuts, between described top anchoring ring and end anchoring ring, connecting bolt is installed.Dacroment preservative treatment is carried out to stone bolt surface, and the sharp edge of removably foot bolt and annex thereof.Before the concrete of concreting cushion cap, first stone bolt is installed and location in foundation bottom.During installation, need, between the nut located on the downside of end anchoring ring and anchoring ring, packing ring is installed.
Often organize bolt assembly and include two connecting bolts, and two connecting bolts are that axisymmetrical is installed with stone bolt, arrange the stability that two connecting bolts can ensure often to organize bolt assembly.
Cushion cap anchoring type blower foundation described in the utility model, can be used for highrise pile cap anchoring type blower foundation and low pile cap anchoring type blower foundation.
Cushion cap anchoring type blower foundation described in the utility model, integral rigidity is large, construction technology is ripe, good endurance, adopt bolt assembly than the blower foundation of pre-embedded foundation ring, reinforcing bar and concrete amount can be saved to a certain extent, blower foundation construction quality and programming all obtain larger raising, improve stability and the economy of whole foundation structure, and the diameter of tower cylinder root stack shell can be reduced to a certain extent, solve a transport difficult problem for tower cylinder, make High-Rise Pile Cap Foundation be promoted in offshore wind farms field and apply.
