Description

Technical Field

[0001] The utility model relates to the field of anchor rods, and more specifically to a foundation bottom plate anti-floating anchor rod node waterproof structure. Background Art

[0002] The underground part of the nuclear island is often very large due to earthquake resistance and nuclear leakage prevention. The conventional island is adjacent to the nuclear island. Due to the deep burial of the circulating water pipes, the underground structure is often also very deep. The part above the ground cannot resist the buoyancy generated by the deep pit, and anti-floating anchors must be installed. However, the part below the ground of the conventional nuclear power island is waterproof level 1, and no water seepage is allowed. Waterproof membranes are often required. The anti-floating anchors are anchored in the concrete base plate. If they penetrate the waterproof membrane, it is easy to create waterproof weak points.
