Prefabricated assembly and cast-in-place concrete combined type fan foundation
The invention discloses a prefabricated assembly and cast-in-place concrete combined type fan foundation. The prefabricated assembly and cast-in-place concrete combined type fan foundation comprises a prefabricated assembly part and a cast-in-place concrete part, the prefabricated assembly part is annular and embedded in the cast-in-place concrete part, and bolts are embedded in the prefabricated assembly part. In combination with the stress characteristics of the fan foundation, the technological characteristics and advantages of prefabricated concrete and cast-in-place concrete are fully utilized, high-strength concrete factory prefabrication is adopted in a main stress area of the foundation structure, so that difficulties that construction points of a wind power plant are scattered, the construction condition is poor, and the construction quality control and supervision difficulty is large are overcome; compared with all cast-in-place construction, the concrete strength pouring quality of the key stress area is well guaranteed; cast-in-place concrete is adopted in a non-main stress area, a lower concrete strength grade is adopted on the premise that the design requirement is met, the construction operation condition is well adapted, and the engineering cost is reduced; the on-site concrete pouring volume is reduced by about 30%, and the construction efficiency of a project site is improved.
本发明公开了一种预制装配与现浇砼组合式风机基础，包括预制装配部分和现浇砼部分，预制装配部分为环形，预制装配部分嵌入现浇砼部分中，预制装配部分预埋螺栓；本发明结合风机基础的受力特点，充分利用了预制砼和现浇砼的工艺特点和优势，在基础结构主要受力区采取高强度混凝土工厂预制，克服了风电场施工点分散、施工条件差、施工质量控制和监管难度大等困难，比全部采取现浇施工更好保证关键受力区混凝土强度浇筑质量；在非主要受力区采取现浇砼，满足设计要求的前提下采取较低混凝土强度等级，更好适应施工作业条件并降低工程成本；现场混凝土浇筑方量减少约30％，提高了项目现场的施工效率。
