Eccentric annular foundation of clinker warehouse and construction method thereof
The invention discloses an eccentric annular foundation of a clinker warehouse and a construction method of the eccentric annular foundation. A prestressed steel strand is arranged between a fixed endanchorage device and a tensioning end anchorage device between adjacent tensioning wall columns, the prestressed steel strand is positioned in a ring beam framework to connect the tensioning wall columns into a whole, the tensile performance of reinforced concrete is improved, the foundation ring beam is eccentrically arranged, and the additional bending moment and shearing force generated by stored materials in the warehouse on the foundation ring beam can be effectively reduced. The prestressed steel strand is arranged outside the section centroid of the foundation ring beam, so that the generation and development of cracks can be effectively resisted, the foundation is prevented from being damaged due to insufficient rigidity, meanwhile, the usage amount of non-prestressed steel bars can be obviously reduced by using the prestressed steel strand, the construction difficulty is effectively reduced, and the construction cost is reduced.
本发明公开了一种熟料库的偏心环形基础及其施工方法，相邻张拉壁柱之间的固定端锚具和张拉端锚具之间设置有预应力钢绞线，预应力钢绞线位于环梁骨架内将张拉壁柱连成一体，提高钢筋混凝土抗拉性能，基础环梁呈偏心设置，可有效降低进而避免库中贮料对基础环梁产生的附加弯矩和剪力，预应力钢绞线布置在基础环梁截面形心外侧，可以有效地抵抗裂缝的产生及发展，避免基础因刚度不足而产生破坏，同时预应力钢绞线的使用可以明显降低非预应力钢筋使用量，有效降低了施工难度，减少施工成本。
