(1)屋頂防水混凝土施工應保證延續澆筑,盡量少留施工縫。當必須留置時,墻體水平施工縫不應留在剪力與彎矩最大處或底板與側墻的交接處,應留在高出底板外觀不小于300㎜高的墻體上;當墻體有預留孔洞時,施工縫距孔洞邊緣不小于300㎜,垂直施工縫應避開地下水和裂隙水較多的地段,并應與交形縫相結合。

(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)水平施工縫澆筑混凝土時,應將其外觀的浮漿和雜物消滅,先鋪凈漿,再鋪30~50㎜厚的1:l水泥砂漿或涂刷混凝土界面處理劑,并要及時撓筑混凝土。

(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)垂直施工縫澆筑混凝土時,應將其外觀清理干凈(網絡營銷培訓),涂刷混凝土界面處理劑,并及時澆筑混凝土。

(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)施工縫采用遇水膨脹橡膠膩子止水條時(新疆人事考試),要將止水條牢固地安放在縫外觀預留槽內。

(4) construction joints by water swellable rubber putty sealing strip, sealing strip should be firmly placed in the joint surface of the reserved groove.
