The invention discloses a leakage plugging structure for a post-cast strip of a civil air defense basement bottom plate and a construction method thereof. The leakage plugging structure comprises a primary water stopping space located on the lower portion and a secondary water stopping space located on the upper portion, the primary water stopping space is of a primary water stopping structure formed by injecting a polyurethane foaming filling layer into a foundation slab post-cast strip construction joint leakage gap; the secondary water stop space is of a secondary water stop structure formed by arranging a U-shaped groove anti-seepage structure layer on the primary water stop space, during construction, a seepage point is determined, a hole is punched along a seepage gap to install a grouting pipe head, the primary water stop space of the polyurethane foaming filling layer is formed in the seepage gap, after grouting is completed, observation is carried out for 8-15 days, after no seepage exists, a grouting groove hole is repaired, after construction of a coiled material waterproof layer is completed, surface layer garbage is cleared away, an isolation layer and a concrete protection layer are constructed from bottom to top, construction of the U-shaped groove anti-seepage structure layer is completed, and the secondary water stop space is formed.
本发明公开了一种人防地下室底板后浇带渗漏封堵结构及其施工方法，包括位于下部的一次止水空间与位于上部的二次止水空间，所述一次止水空间为“通过在基础底板后浇带施工缝渗漏缝隙中注入聚氨酯发泡填充层”形成的一次止水结构；所述二次止水空间为“在一次止水空间上设置U型槽防渗漏结构层”形成的二次止水结构，施工时确定渗漏点，沿渗漏缝隙部位打孔安装注浆管头，在渗漏缝隙中形成聚氨酯发泡填充层一次止水空间，注浆完成后，观察8‑15天，无渗漏后，修补注浆槽孔，在卷材防水层施工完毕后，清理表层垃圾，从下之下施工隔离层，混凝土保护层，完成U型槽防渗漏结构层施工，形成二次止水空间。
