Underground engineering post-cast strip waterproof construction method
The invention discloses an underground engineering post-cast strip waterproof construction method. The waterproof construction method comprises the steps that 1500-2000 mm of a post-cast strip is reserved in the design position of the post-cast strip, and the post-cast strip sinks 100 mm to serve as a slag collecting groove of the post-cast strip; a sunken cushion layer is arranged in the post-cast strip, and bottom ribs are arranged; pre-laid coiled materials are continuously laid on the cushion layer, and a half-seam isolation piece is additionally arranged on the pre-laid coiled materials in the middle of the post-cast strip; a concrete protection layer is arranged on the pre-laid coiled materials, reinforcing steel bars which are bent upwards to be as high as the bottom plate body are arranged in the protection layer, disassembly-free mesh templates are arranged on the two sides of the post-cast strip and used for interface shaping of the post-cast strip, mesh templates are arranged on the upwards-bent reinforcing steel bars in a spot welding mode, and the mesh templates extend downwards to the inclined face of a slag collecting groove of the post-cast strip according to needs and are fixed in a spot welding mode; the mesh templates are provided with water swelling adhesive tapes; and the protection layer and the bottom plate body are poured simultaneously. According to the invention, the post-cast strip pre-paved coiled material is continuously sealed, and the method can adapt to large deformation, resist floating water pressure in a short time and facilitate slag removal.
本发明公开了一种地下工程后浇带防水构造方法，包括：在后浇带的设计位置预留1500㎜～2000㎜并下沉100㎜作为后浇带的集渣槽；在后浇带内设置下沉式垫层并配置底筋；垫层之上连续铺设预铺卷材并在后浇带居中位置之预铺卷材之上加置半缝隔离片；预铺卷材之上设置砼保护层，保护层内配置上弯至与底板主体同高的钢筋，后浇带两侧设置免拆网孔模板用于后浇带界面定型，网孔模板点焊在上弯的钢筋之上，网孔模板根据需要下延至后浇带的集渣槽的斜面处并点焊固定；网孔模板设置有遇水膨胀胶条；保护层与底板主体同时浇筑。本发明使后浇带预铺卷材连续密封、能适应较大变形、短时抗上浮水压及方便清渣。
