施工缝渗水怎么办

 文章来源:http://www.jnldfs.com/ 发布时间:2022-03-04   

墙体水平施工缝不应留在剪力或底板与边墙交接处,而应留在墙体上,高出底板表面不小于500mm。避开地下水和裂隙水较多的地段。
The horizontal construction joint of the wall shall not be left at the shear force or the junction between the bottom plate and the side wall, but shall be left on the wall, which shall not be less than 500mm higher than the surface of the bottom plate. Avoid areas with more groundwater and fissure water.
垂直施工缝浇筑混凝土前,应将表面凿毛、清理干净,涂刷界面剂,及时浇筑混凝土;
Before pouring concrete for vertical construction joints, the surface shall be roughened and cleaned, the interface agent shall be applied, and the concrete shall be poured in time;
水平施工缝浇筑混凝土前,应清理干净表面浮浆及杂物,直至坚实部分。先涂水泥浆或界面剂,然后铺30~50mm厚1:1水泥砂浆,调整相对平整度。安装膨胀止水胶,及时浇筑混凝土。
Before pouring concrete into the horizontal construction joint, the laitance and sundries on the surface shall be cleaned until the solid part. First apply cement slurry or interface agent, then pave 30 ~ 50mm thick 1:1 cement mortar, and adjust the relative flatness. Install expansion water stop glue and pour concrete in time.
钢边橡胶止水带施工技术要求与预埋钢边橡胶止水带变形缝施工技术要求相同。
The technical requirements for the construction of steel edge rubber waterstop are the same as those for the construction of deformation joint of embedded steel edge rubber waterstop.
止水胶应采用专用注胶器挤出,注胶器应连续、均匀、饱满、无气泡和孔洞。止水胶应紧密附着在施工缝的基面上,中间不存在空鼓、分离等现象。一旦止水胶提前损坏或膨胀,应将其切断,并在切断处重新粘贴止水胶。
The water stop glue shall be extruded with a special glue injector, which shall be continuous, uniform, full and free of bubbles and holes. The water stop glue shall be closely attached to the base surface of the construction joint, and there shall be no hollowing, separation and other phenomena in the middle. Once the water stop adhesive is damaged or expanded in advance, it shall be cut off and the water stop adhesive shall be pasted again at the cut-off point.
挤出成型后,养护期一般为24小时,并提前做好临时防护,避免水膨胀或施工损坏。止水橡胶表面干燥后,方可进行混凝土浇筑。
After extrusion molding, the curing period is generally 24 hours, and temporary protection shall be done in advance to avoid water expansion or construction damage. Concrete pouring can be carried out only after the surface of water stop rubber is dry.
