Elevator foundation platform construction method
The invention discloses an elevator foundation platform construction method. The method comprises the following steps that a foundation pit is excavated, the bottom of the foundation pit is bulldozed,and all sundries in the foundation pit are removed; a packing layer is laid at the bottom of the foundation pit, wherein the packing layer is formed by mixing gravels and plain soil; the packing layer is rammed and compacted through a rammer; and a plurality of longitudinal reinforcing steel bars are laid in the length direction of the foundation pit, a plurality of transverse reinforcing steel bars are laid in the width direction of the foundation pit, the overlapping positions of the longitudinal reinforcing steel bars and the transverse reinforcing steel bars are bound together through metal wires, concrete is poured into the foundation pit and flattened, and an elevator foundation platform is formed after the concrete is condensed. By the adoption of the technical scheme, the compaction effect is improved by laying the packing layer in a layered manner and conducting dynamic compaction in a layered manner, later settlement can be reduced, the structural strength and bearing capacity of the concrete layer are enhanced by selecting high-strength-grade concrete, arranging a reinforcing mesh in the concrete layer and the like, the stability of a foundation is guaranteed, and the foundation safety is improved.
本发明公开了一种升降机基础承台施工方法，包括以下步骤：挖掘基坑，推平基坑坑底并清除基坑内所有杂物；在基坑坑底铺设一层填料层，填料层由碎石和素土混合而成；通过夯锤夯击压实填料层；分别沿着基坑长度方向铺设多根纵向钢筋，沿着基坑宽度方向铺设多根横向钢筋，再将纵向钢筋与横向钢筋交叠处使用金属丝绑扎在一起，再向基坑内浇筑混凝土并摊平，待混凝土凝结后形成升降机基础承台。采用本发明的技术方案，通过采用分层铺设填料层、分层强夯的方式，提升了压实效果，可以减少后期的沉降，还通过选用高强度等级的混凝土，在混凝土层内设置钢筋网等措施，增强混凝土层的结构强度和承载能力，保证了地基的稳定，提高地基安全性。
