    1、基础要求
    1. Basic requirements
    强度达建筑混凝土C20强度以上,平整度为3m直尺误差≤3mm,有一定排水坡度(一般横向≤8‰,纵向≤2‰),混凝土浇铸后必须保水养护不少于7天,总养护期不少于28天.

    The strength of the building concrete is above C20 strength, the levelness is 3M straight ruler error less than 3mm, and there is a certain drainage gradient (general transverse < 8 per thousand, longitudinal less than 2 per thousand). The concrete casting must maintain water maintenance for not less than 7 days, and the total maintenance period is not less than 28 days.

    2、切割温度缝
    2, cutting temperature seam
    新水泥基础浇铸后必须切割合理温度伸缩缝,原则以不大于6×10m为一方块切割,浇铸施工板块间必须切割温度缝,温度缝宽为5~8 mm,缝深不少于20 mm,以保证基础热胀冷缩能集中在温度缝中变化,不导致基础其它地方开裂。
    After the new cement foundation casting, the reasonable temperature expansion joint must be cut, the principle is not more than 6 x 10m for one square block, the casting construction plate must cut the temperature seam, the temperature seam width is 5~8 mm, the seam depth is not less than 20 mm, in order to ensure the foundation thermal expansion and cold contraction can be concentrated in the temperature seam, and do not cause the cracks in other parts of the foundation.
    3、酸洗
    3. Pickling
    以清水润湿基面,用8%左右的稀盐酸泼洒并洗刷基面,再用清水冲洗干净,并圈划出积水处,清洗干燥后基面应无白色粉化物及浮松物。
