Advanced water stop construction method for post-cast strip of foundation slab
The invention discloses an advanced water stop construction method for a post-cast strip of a foundation slab. The advanced water stop construction method comprises the steps that earth excavation is conducted in a front water stop area; constructing a foundation concrete cushion layer; a waterproof coiled material is laid in the advanced water stop area; a water stop belt is arranged; binding reinforcing steel bars in an advanced water stop area; a water stop caulking is filled; the advanced water stop area is sealed by concrete; a waterproof roll is laid in the foundation pre-pouring area; binding steel bars in the pre-pouring area and the pre-pouring area; mounting a water stop steel plate and a steel wire mesh; pouring concrete in a foundation pre-pouring area; the waterproof coiled material is directly laid on the concrete cushion layer in an empty mode, and the coiled material sand-coated surface is tightly combined with the concrete structure layer, so that the coiled material and the concrete generate high adhesive force, the traditional water channeling problem is solved, a coiled material protection layer does not need to be arranged, the working procedure is simplified, construction is convenient, and the front water stopping area and the foundation pre-pouring area are poured separately; the construction is firstly carried out, the advanced water stopping area can be closed early, the exposure time of the advanced water stopping area is shortened, and the advanced water stopping effect is achieved as soon as possible.
本发明公开了一种用于基础底板后浇带超前止水施工方法，包括前止水区土方开挖；施工基础混凝土垫层；超前止水区铺设防水卷材；设置止水带；超前止水区钢筋绑扎；填充止水嵌缝；超前止水区混凝土封闭；基础先浇区铺设防水卷材；先浇区和先浇区钢筋绑扎；止水钢板及钢丝网安装；基础先浇区混凝土浇筑；基础后浇区封闭，其中，采用防水卷材直接空铺在混凝土垫层上，并通过卷材覆砂面与混凝土结构层紧密结合，使卷材与混凝土产生较强的粘附力，解决传统窜水问题，无需设置卷材保护层，工序简化，施工方便，前止水区与基础先浇区分开浇筑，率先施工，能够较早的封闭超前止水区，减少超前止水区的暴露时间，从而尽早实现超前止水效果。
