Large-size building foundation construction method
The invention discloses a large-size building foundation construction method which includes the steps of step 1, fixing and supporting a formwork required by foundation pouring through a supporting rod, firmly fixing the foundation formwork through an external supporting structure, setting a certain prestress change range for the formwork at a vertical part, and ensuring the foundation concrete pouring molding size to meet design requirements. The construction method has the beneficial effects that heat preservation is conducted through a heat preservation pad and a heat preservation film, so that the large-size building foundation construction method is improved; and when construction is conducted in a low-temperature environment, the outer layer of a concrete foundation of a building is isolated from an external low-temperature environment through the heat preservation pad and the heat preservation film, so that water in concrete is prevented from freezing and expanding the concrete, the outer layer of the foundation is prevented from cracking, and the forming quality of the foundation is guaranteed.
本发明公开了一种大体积建筑基础施工方法，它包括以下步骤：步骤1：将基础浇筑需要的模板通过支撑杆进行固定支护，基础模板通过外部支撑结构固定牢固，垂直部位的模板设定一定的预应力变化范围，确保基础混凝土浇筑成型尺寸满足设计要求。有益效果在于：本方法通过保温垫和保温膜进行保温的施工方法，使得大体积建筑基础施工方法得到改善，在遇到低温环境的情况下施工时，建筑的混凝土基础外层通过保温垫和保温膜与外部低温环境隔离，避免混凝土中的水分结冰将混凝土撑开，进而避免基础外层出现裂缝，保证基础的成型质量。
