Description

Technical Field

[0001] The utility model belongs to the field of construction engineering, in particular to a waterproof structure suitable for anti-floating anchor rod parts. Background Art

[0002] Anti-floating anchor rods are a kind of anti-floating measures for underground structures in construction projects. Anti-floating anchor rods refer to structural components set up to resist the upward displacement of the buildings above them. They are related to the height and changes of the groundwater level and are opposite to the force direction of the compression piles.

[0003] The existing patent number is CN205502001U, and the patent name is a utility model patent for an anti-floating anchor waterproof structure, which records that the patent includes an anchor, a water stop strip, asphalt paste, a concrete platform, a penetrating crystallization coating, a waterproof protective layer and a positioner; the concrete platform is arranged at one end of the anti-floating anchor device; the water stop strip is arranged just above the middle of the concrete platform; the asphalt paste is tightly attached to the middle of the water stop strip and the concrete platform; the penetrating crystallization coating is arranged under the concrete platform and is closely connected to the concrete platform; the waterproof protective layer is arranged at the lower end of the penetrating crystallization coating and is close to the penetrating crystallization coating; the anchor is arranged in the middle of the entire device and is placed vertically to penetrate the entire device; the positioner is arranged at the lower end of the anchor and is embedded in the anchor; the anti-floating anchor waterproof structure shortens the construction period, saves construction costs, waterproofs the anchor nodes, effectively solves the leakage problem of the anti-floating anchor, and is suitable for popularization and use.

[0004] When the above-mentioned device is used, the waterproof treatment of the anti-floating anchor reinforcement is mostly carried out with coiled material + water-expandable water stop ring + waterproof sealant. This method cannot ensure the tightness of the coiled material and the anchor reinforcement, the density of the sealant filling, and the construction is difficult. Once the anti-floating anchor leakage is improperly handled, on the one hand, the leakage at the root of the anchor cannot be cured, and on the other hand, since the waterproofing coiled material is not tightly combined with the raft, there is a risk of water leakage, and the specific leakage point cannot be found, and the subsequent treatment is very troublesome;

[0005] In summary, the existing waterproof structure suitable for the anti-floating anchor rod part has certain drawbacks when used and does not meet people's use requirements. Therefore, we propose a waterproof structure suitable for the anti-floating anchor rod part. Summary of the invention
