(1)屋顶防水混凝土施工应保证延续浇筑，尽量少留施工缝。当必须留置时，墙体水平施工缝不应留在剪力与弯矩最大处或底板与侧墙的交接处，应留在高出底板外观不小于300㎜高的墙体上；当墙体有预留孔洞时，施工缝距孔洞边缘不小于300㎜，垂直施工缝应避开地下水和裂隙水较多的地段，并应与交形缝相结合。
(1) waterproof concrete construction should ensure continuous casting, as far as possible to keep the construction joints.When must keep, should not stay at the junction of the shear force and bending moment at the maximum or the bottom plate and the side wall of the horizontal seam wall construction, should stay in the high floor surface of not less than 300 mm high on the wall; when the wall has reserved holes, construction joints of not less than 300 mm from the edge of the hole, should avoid more groundwater and fissure lot of water seam vertical construction, and should pay and slot combination.
(2)水平施工缝浇筑混凝土时，应将其外观的浮浆和杂物消灭，先铺净浆，再铺30～50㎜厚的1：l水泥砂浆或涂刷混凝土界面处理剂，并要及时挠筑混凝土。
(2) the horizontal construction joint pouring concrete, should be on the surface of the mud and debris removal, spreading the paste, then 30 ~ 50 mm thick 1:l coating of cement mortar or concrete interfacial treatment and timely deflection of concrete.
(3)垂直施工缝浇筑混凝土时，应将其外观清理干净(网络营销培训)，涂刷混凝土界面处理剂，并及时浇筑混凝土。
(3) when the concrete is poured in the vertical construction joint, the surface should be cleaned up, and the concrete interface treatment agent should be brushed, and the concrete will be poured in time.
(4)施工缝采用遇水膨胀橡胶腻子止水条时(新疆人事考试)，要将止水条牢固地安放在缝外观预留槽内。
(4) construction joints by water swellable rubber putty sealing strip, sealing strip should be firmly placed in the joint surface of the reserved groove.
