Description
Technical field
The utility model relates to a kind of bearing platform type blower foundation, and especially a kind of have the blower foundation that pressure dispersing type arranges high-strength prestressed anchor bar/anchor cable.Be applicable to land, Oversea wind power generation industry.
Background technology
Bearing platform type blower foundation main part is made up of foundation pile (material such as steel pipe pile or PHC) and concrete bearing platform usually, according to the relativeness in cushion cap and sea bed face, low pile cap basis and High-Rise Pile Cap Foundation can be divided into, the former can be applicable to land or intertidal zone fan is basic, and the latter can be used for offshore wind turbine foundation.
For bearing platform type blower foundation, the connection of concrete bearing platform and foundation pile is the key point designed, particularly increase with Wind turbines single-machine capacity, fan loads magnitude constantly promotes, bearing platform type blower foundation designs, particularly the importance of the design of cushion cap and foundation pile connecting portion more highlights, and foundation pile conveniently embeds concrete bearing platform and coordinates the arrangement of reinforcement measures such as reinforcing cage, cushion cap engineering quantity relatively large (specification has the requirement of insert depth).
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing, there is provided that a kind of structure is simple, easy construction, lower-cost there is the blower foundation that pressure dispersing type arranges high-strength prestressed anchor bar/anchor cable, to improve the switching performance of bearing platform type blower foundation foundation pile and cushion cap, and reduce cushion cap engineering quantity.
The technical scheme that the utility model adopts is: a kind of have the blower foundation that pressure dispersing type arranges high-strength prestressed anchor bar/anchor cable, comprise cushion cap, circumferentially equidistantly the stake of many foundation is arranged bottom cushion cap, cushion cap top connects tower of wind generating set cylinder, it is characterized in that: described foundation pile inside is separated into upper and lower two parts by shrouding, shrouding take upper part as slip casting section, anchor plate is positioned at the different depth position of stake injecting cement paste, in described slip casting section, some anchor plates are set, the high-strength prestressed anchor pole of scattering device many groups or anchor cable in slip casting section, often organize anchor pole or the corresponding anchor plate of anchor cable, anchor pole or anchor cable lower end are fixedly linked by slip casting and foundation pile in anchor plate and slip casting section, anchor pole or anchor cable upper end are anchored in cushion cap top, described high-strength prestressed anchor pole or anchor cable outsourcing plastic bushing.
Described foundation pile inwall arranges shear connector.
Described foundation pile is steel pipe pile or PHC stake.
8 foundation stakes are arranged bottom described cushion cap.
Described high-strength prestressed anchor pole or anchor cable are coated with bag anticorrosion grease outward.
The beneficial effects of the utility model are: structure of the present invention is simple, easy construction, cost are lower, by the high-strength prestressed anchor bar/anchor cable of step-by-step arrangement in foundation pile many groups, is connected by foundation pile, enhances switching performance, and reduce cushion cap engineering quantity with cushion cap.

Fig. 2 is the layout plan of Fig. 1.
Fig. 3 is the structural representation on low pile cap basis in embodiment 2.
Detailed description of the invention
Embodiment 1: as shown in Figure 1 and Figure 2, the present embodiment is High-Rise Pile Cap Foundation, comprises cushion cap 2 and foundation pile 3 (being generally steel pipe pile), and cushion cap 2 higher than sea bed face 9, and according to design needs, determines the relativeness on itself and sea level 8.Wherein cushion cap 2 comprises first phase bottom concrete 2.1 and the second stage of main body concrete 2.2, and cushion cap 2 top is connected with tower of wind generating set cylinder 1, and many (the present embodiment is 8) foundation piles 3 are circumferentially equidistantly arranged in bottom.Foundation pile 3 inside arranges shrouding 7, foundation pile 3 inner space is separated into upper and lower two parts by shrouding 7, shrouding is that slip casting section (also can according to design needs with upper part, certain depth place under mud face or mud in slip casting to stake), two pieces of anchor plates 5 (or anchor head is set in slip casting section, concrete quantity can need to determine according to design), two anchor plates 5 (or anchor head) are positioned at slip casting section differing heights.Scattering device two groups of high-strength prestressed anchor poles or anchor cable 4 in slip casting section, often organize anchor pole or the corresponding one piece of anchor plate 5 (or anchor head) of anchor cable, anchor pole or anchor cable lower end are fixedly linked with foundation pile 3 by corresponding anchor plate 5 (or anchor head) and the slip casting 6 be poured in slip casting section, and anchor pole or anchor cable upper end are anchored in cushion cap 2 top.In cushion cap 2 and foundation pile 3 slip casting section according to relevant Regulations requirement, carry out arrangement of reinforcement.In this example, high-strength prestressed anchor pole or anchor cable 4 outside scribble anticorrosion grease and be surrounded by plastic bushing outside them.
The present embodiment is in work progress, first carry out foundation pile 3 pile sinking, then according to the high-strength prestressed anchor pole of design arrangement or anchor cable 4 and anchor plate 5 (or anchor head), carry out the construction workings such as the concreting of relevant reinforcing cage, first phase bottom concrete 2.1 and the second stage of main body concrete 2.2 of slip casting and cushion cap 2 in foundation pile 3 again, after cushion cap 2 intensity reaches designing requirement, prestressed stretch-draw and locking, anchoring are carried out to the high-strength prestressed anchor pole arranged in advance or anchor cable 4, and carries out the protection at anchor head position.
Embodiment 2: as shown in Figure 3, the present embodiment is low pile cap basis, be applicable to land and intertidal belt wind electric field, the present embodiment structure is substantially the same manner as Example 1, difference is only that cushion cap 2 is for low cushion cap, and namely cushion cap is positioned near sea bed face 9 (intertidal zone) or ground (land); Foundation pile 3 material can be steel pipe pile or PHC stake usually.
