Gravity type fan foundation and construction method thereof
The invention relates to the technical field of fan foundations, and provides a gravity type fan foundation and a construction method thereof. The main body is arranged on the cushion layer, and a cylindrical first core filling area is arranged in the middle of the main body; the second core filling area is cylindrical, is arranged between the cushion layer and the main body and is used for filling a light material, and the second core filling area and the first core filling area are coaxially arranged and have the same section radius; the second core filling area used for being filled with the light materials is additionally arranged in the center of the bottom of the main body, the stress mode of the bottom of the foundation is changed, stress distribution of the bottom of the foundation is converted into annular bottom face distribution from traditional circular full-area distribution, the center area does not transmit loads to the foundation any more, the loads are concentrated in the annular area of the edge of the foundation, and therefore the foundation is protected. The load density of the unit area in the annular area is increased, the minimum pressure of the bottom of the foundation is effectively improved, the stability of the foundation is enhanced, and the risk that the bottom of the foundation is disengaged is reduced.
本发明涉及风机基础技术领域，提供一种重力式风机基础及其建造方法，重力式风机基础，包括：垫层；主体，设置在垫层上，主体的中部设置有圆柱形的第一填芯区；第二填芯区，设置为圆柱状，且设置垫层与主体之间，用于填充轻质材料，第二填芯区与第一填芯区同轴设置且截面半径相同；本发明通过在主体的底部中心处增设用于填充轻质材料的第二填芯区，改变了基础底部的受力模式，基础底部的受力分布从传统的圆形全面积分布转变为环形底面分布，中心区域不再传递载荷到地基，载荷被集中在基础边缘的环形区域，环形区域内的单位面积上的载荷密度增加，有效地提高了基础底部的最小压力，增强了基础的稳定性，减少了基础底部脱开的风险。
