Description
Technical field
The utility model relates to the basic engineering technical field of offshore wind farm industry, particularly relates to a kind of prestressed anchor embedding rock offshore wind turbine High-Rise Pile Cap Foundation.
Background technology
The maximum difference of Oversea wind power generation and land wind-power electricity generation is the position that both are residing, because the basis of offshore wind farm unit is in sea, add much extra load and uncertain factor, thus design comparatively complicated, the form of structure also variation due to different sea situations.What the fixed basis of batholith sea bed offshore wind farm unit was the most frequently used has 2 kinds, embedding rock formula single pile, gravity.But embedding rock formula single-pile foundation needs to use large-scale embedding rock drilling machine, and domestic do not have similar equipment; Gravity type foundation needs to use large-scale " centipede car " for transporting in precasting yard, and the equipment such as large-scale floating crane, and this type of equipment domestic lacks.
Therefore, need to provide a kind of prestressed anchor embedding rock offshore wind turbine High-Rise Pile Cap Foundation to solve the problems referred to above.
Utility model content
In order to solve this problem, the utility model discloses a kind of prestressed anchor embedding rock offshore wind turbine High-Rise Pile Cap Foundation, it solve and use domestic existing weaponry and equipment and traditional construction skill, in the problem of the large megawatt blower foundation of batholith sea bed construction, use prestressed anchor technique simultaneously, decrease marine embedding rock engineering quantity, improve work efficiency, reduce construction cost.A kind of prestressed anchor embedding rock offshore wind turbine High-Rise Pile Cap Foundation, its composition comprises: steel pipe pile (1), concrete bearing platform (2), pile tube (3), crashproof component (4), cat ladder (5), outer platform (6), steel pipe pile upper end concrete (7), steel pipe pile lower end concrete (8), sea level (9), sea bed (10), mud (11), chiltern viscous soil horizon (12), completely decomposed granite (13), strong weathered granite layer (14) and middle weathering sial (15), it is characterized in that, described concrete bearing platform (2) is cylinder, be connected between steel pipe pile (1) and pile tube (3), described crashproof component (4) is arranged on the surface of concrete bearing platform (2), described cat ladder (5) is arranged on the surface of concrete bearing platform (2) and pile tube (3), nine cylindrical steel pile tubes (1) are arranged under described concrete bearing platform (2), under steel pipe pile (1) lower end pile sinking to sea bed (10), squeeze into mud (11), chiltern viscous soil horizon (12), completely decomposed granite (13), strong weathered granite layer (14), steel pipe pile (1) interior upper and lower side pours into steel pipe pile upper end concrete (7), steel pipe pile lower end concrete (8) respectively, prestressed anchor upper end is fixed in steel pipe pile (1), and lower end is fixedly installed on middle weathering sial (15).
Preferably, the utility model adopts embedding rock+High-Rise Pile Cap Foundation scheme, and for improving work efficiency, uses the embedding rock of prestressed anchor Substitute For Partial in bottom.
The beneficial effects of the utility model are:
The utility model makes domestic employing traditional handicraft and common construction equipment complete the construction of batholith sea bed offshore wind turbine foundation, and stake can bear horizontal force and axial force, and bore diameter is little, efficiency of construction high advantage.
Advantage of the present utility model and feature is described in detail in conjunction with following.
Accompanying drawing explanation
Fig. 1 is organizational styucture schematic diagram of the present utility model;
Detailed description of the invention
Below embodiment of the present utility model is described in detail.
With reference to shown in Fig. 1, a kind of prestressed anchor embedding rock offshore wind turbine High-Rise Pile Cap Foundation, its composition comprises: steel pipe pile (1), concrete bearing platform (2), pile tube (3), crashproof component (4), cat ladder (5), outer platform (6), steel pipe pile upper end concrete (7), steel pipe pile lower end concrete (8), sea level (9), sea bed (10), mud (11), chiltern viscous soil horizon (12), completely decomposed granite (13), strong weathered granite layer (14) and middle weathering sial (15), it is characterized in that, described concrete bearing platform (2) is cylinder, be connected between steel pipe pile (1) and pile tube (3), described crashproof component (4) is arranged on the surface of concrete bearing platform (2), described cat ladder (5) is arranged on the surface of concrete bearing platform (2) and pile tube (3), nine cylindrical steel pile tubes (1) are arranged under described concrete bearing platform (2), under steel pipe pile (1) lower end pile sinking to sea bed (10), squeeze into mud (11), chiltern viscous soil horizon (12), completely decomposed granite (13), strong weathered granite layer (14), steel pipe pile (1) interior upper and lower side pours into steel pipe pile upper end concrete (7), steel pipe pile lower end concrete (8) respectively, prestressed anchor upper end is fixed in steel pipe pile (1), and lower end is fixedly installed on middle weathering sial (15).
Preferably, the utility model adopts embedding rock+High-Rise Pile Cap Foundation scheme, and for improving work efficiency, uses the embedding rock of prestressed anchor Substitute For Partial in bottom.
Preferably, the loose earth on bedrock surface in stake and completely decomposed granite, part strong weathered granite, after pile foundation pile sinking completes, are removed clean, concreting bed course on stake stomidium by the utility model, and levelling.Carry out drilling construction after concrete cushion is located each anchor hole center, should guarantee that the anchoring section of prestressed anchor is arranged in intact basement rock.After boring terminates, petrosal foramen is cleaned up, rear grout injection, finally after the outer anchor pier of concrete and grouted part injecting cement paste compressive strength all reach design strength, stretch-draw can be carried out to prestressed anchor; Prestressed anchor anchoring must anchor in micro-weathered rock formation, and in strongly weathered sand-rock, boring needs to carry out retaining wall, to prevent collapse hole.
