Land wind power foundation structure capacity expansion method adopting external water tank
The invention relates to a land wind power foundation structure capacity expansion method adopting an external water tank, an original wind power foundation structure is a common wind power expansion foundation, the original wind power foundation structure comprises an original foundation ring with annular anchor plates welded on the upper portion and the lower portion, and the inner side of the original foundation ring is poured to form an original center stand; the outer side of the original foundation ring is poured to form an original external stand; an extension flange, an extension tower drum flange and a new tower drum are sequentially and fixedly installed on an original foundation ring, a plurality of tower drum cross arms and a plurality of annular water tanks communicated with the tower drum cross arms are evenly arranged on the peripheral side of the extension flange, and a new middle stand used for fixing the tower drum cross arms is formed on the outer side of the extension tower drum flange in a pouring mode. An extension plate is mounted outside the original extended foundation, and a supporting rod is fixedly mounted at the lower part of the annular water tank; according to the wind power foundation structure, the bearing capacity and the anti-overturning performance of the foundation are improved mainly through the prefabricated water tank filled with water, the extension plates, the rod pieces and the inhaul cables, so that foundation capacity expansion is achieved, construction is more convenient and rapid, and the material cost and the construction cost are reduced.
本发明涉及一种采用外加水箱式的陆上风电基础结构扩容方法，原有的风电基础结构为常见的风电扩展基础，包括上下焊接有环形锚板的原基础基础环，原基础基础环内侧浇筑成型为原中心台柱，原基础基础环外侧浇筑成型为原外部台柱；在原基础基础环上依次固定安装有扩建法兰、扩建塔筒法兰和新塔筒，扩建法兰周侧均匀布置若干根塔筒横撑和与塔筒横撑贯通的若干个环状水箱，扩建塔筒法兰外侧浇筑成型有用于固定塔筒横撑的新中部台柱，原扩展基础外安装有扩建板，环状水箱下部固定安装有支撑杆；该风电基础结构主要通过预制水箱装填水、扩建板、杆件及拉索提高基础的承载能力及抗倾覆性能来实现基础扩容，更加方便快速施工且减少了材料成本及施工成本。
