Waterproof structure of anti-floating anchor rod

The utility model relates to the technical field of building waterproofing, in particular to a waterproof structure of an anti-floating anchor rod. The anti-floating anchor rod waterproof structure comprises a galvanized water stop steel pipe, a water swelling water stop strip and a water stop seal. The bottoms of the galvanized water-stop steel pipes are located at the bottoms of the circular pits. The water swelling strip is annularly adhered to the bottom end of the galvanized water stop steel pipe; the water stop seal is arranged in the circular pit and located on the outer side of the galvanized water stop steel pipe. The anti-floating anchor rod waterproof structure can prevent underground water from leaking upwards. 本实用新型涉及建筑防水技术领域，尤其是涉及一种抗浮锚杆防水结构。本抗浮锚杆防水结构，包括镀锌止水钢管、遇水膨胀止水条和止水密封；镀锌止水钢管底部位于圆形凹坑底部；遇水膨胀止水条环向黏贴于镀锌止水钢管底端；止水密封设置在圆形凹坑内，且位于镀锌止水钢管外侧。该抗浮锚杆防水结构能够防止地下水向上渗漏。
