Method for capacity increasing transformation of existing wind power plant fan foundation
The invention relates to the technical field of wind power generation, and particularly discloses a method for capacity increasing transformation of an existing wind power plant fan foundation, which comprises the following steps of: S1, destroying concrete on the periphery of a pier in the original fan foundation, excavating to the lower part of a foundation bottom plate, and installing a first anchor rod; s2, a plurality of supporting columns of reinforced concrete structures are installed on the periphery and in the middle of the foundation middle pier; s3, a plurality of groove holes are horizontally dug in the outer side concrete in the radial direction of the original foundation ring, and second anchor rods are installed; s4, a plurality of inner ring bolts are installed on the top of the original foundation ring; s5, a new foundation ring with the diameter larger than that of the original foundation ring and smaller than that of the foundation middle pier is installed on the outer side of the original foundation ring; s6, an upper bearing plate is fixedly installed on the foundation middle pier; and S7, a gradienter is installed on the side wall of the upper bearing plate. According to the method, deep excavation damage to the original fan foundation in the transformation process can be avoided, the construction difficulty is reduced, the construction efficiency is improved, and the construction is more feasible.
本发明涉及风力发电技术领域，具体公开了一种对既有风电场风机基础进行增容改造的方法，包括以下步骤：S1、破坏原风机基础中墩外围的混凝土，开挖至基础底板下方，安装第一锚杆；S2、在基础中墩外围以及中部安装若干钢筋混凝土结构的支撑柱；S3、沿原基础环径向在外侧混凝土上水平开凿出若干槽孔，安装第二锚杆；S4、在原基础环顶部安装若干内圈螺栓；S5、在原基础环外侧安装一个直径大于原基础环并小于基础中墩的新基础环；S6、在基础中墩上固定安装一块上承板；S7、在上承板侧壁安装水平仪。本发明可避免改造过程中对原风机基础的深度开挖破坏，降低施工难度，提高施工效率，使施工更具可行性。
