The invention provides a winter construction method. The winter construction method comprises the following steps that S1, an earthwork backfilling area is determined, and earthwork backfilling is conducted on the earthwork backfilling area according to design requirements; S2, steel bars are laid in the area where earthwork backfilling is completed according to the design requirements; S3, after the steel bars are laid, a concrete forming formwork is installed, the concrete forming formwork is a composite wood formwork, the middle layer of the composite wood formwork is formed by compressing and bonding wood chips, and the outer layer of the composite wood formwork is a three-ply board; S4, after the concrete forming formwork is installed, pouring of a raft is started, and a specially-assigned person is arranged to be matched in a steel bar frame to lay temperature measuring pipes during concrete pouring; and S5, after the concrete is poured, construction of a masonry project is started when the strength of the concrete meets the design requirement, masonry is stopped when an environment temperature is lower than-10 DEG C, the temperature of mortar used for the masonry is T1, the temperature of mortar mixing water is T2, and when the masonry height exceeds 1.8 m, a scaffold is in lap joint to assist the masonry.
本发明提出一种冬季施工方法，包括如下步骤：S1:确定土方回填区域，根据设计要求对所述土方回填区域进行土方回填；S2：在已经完成土方回填的区域按设计要求铺设钢筋，S3:所述钢筋铺设完成后，安装混凝土成型模板，所述混凝土成型模板采用复合木模板，所述复合木模板中间层由碎木屑压缩粘接而成，外层为三合板；S4:所述混凝土成型模板安装完成后，开始浇筑筏板，混凝土浇筑时设专人配合在钢筋框架内布设测温管；S5:混凝土浇筑后，待混凝土强度达到设计要求开始砌筑工程的施工，当环境温度低于‑10℃时停止砌筑，砌筑使用的砂浆的温度为T1，砂浆拌合水的温度为T2，当砌筑高度超过1.8m时搭接脚手架辅助砌筑。
