Fan cylindrical foundation composed of underground diaphragm wall and construction method
The invention relates to a fan cylindrical foundation composed of an underground diaphragm wall and a construction method. The fan cylindrical foundation comprises a reinforced concrete bearing platform and the underground diaphragm wall, wherein the reinforced concrete bearing platform is connected with a fan tower; the underground diaphragm wall is embedded into the bottom face of the reinforced concrete bearing platform and connected with the bottom face of the reinforced concrete bearing platform into a whole; the underground diaphragm wall is in a polygonal cylinder shape; reinforced concrete guide walls playing a role in guiding and fixing during construction are arranged on the inner side and the outer side of the underground diaphragm wall; and the underground diaphragm wall comprises a plurality of unit wall sections which are evenly arranged along the circumference and connected end to end in a closed-loop mode. Compared with the prior art, the problem that undisturbed soil is damaged during heavy excavation or open caisson construction can be avoided, and compared with a conventional pile foundation, the construction period is short, and economical efficiency is good.
本发明涉及一种由地下连续墙组成的风机筒形基础及施工方法，所述风机筒形基础包括钢筋混凝土承台和地下连续墙，所述钢筋混凝土承台与风机塔筒连接，所述地下连续墙嵌入钢筋混凝土承台的底面，连接为整体，所述地下连续墙呈多边形筒状，内外侧设有在施工时起到导向和固定作用的钢筋混凝土导墙，所述的地下连续墙包括沿着圆周均匀布置、且首尾连接闭环的若干单元墙段。与现有技术相比，本发明不仅可以避免大开挖、或沉井施工时破坏原状土的问题，而且相比常规的桩基础工期短、经济性良好。
