Description

TECHNICAL FIELD

[0001] The utility model relates to anti -floating anchor rod technical field, specifically a kind of anti -floating anchor rod end waterproof structure. BACKGROUND

[0002] The existing anti-floating anchor rod head waterproof construction method uses waterproof rubber sleeve ring, after the waterproof construction of bottom plate is completed, water-swelling water-stopping cement is filled in the waterproof rubber sleeve ring, to achieve the effect of anti-floating anchor rod head waterproof.

[0003] However, for the case that the thickness of basement bottom plate bottom layer reinforcement waterproof protection layer is inconsistent, various specifications need to be used, and for the case without corresponding size specifications, customized waterproof rubber sleeve ring needs to be carried out, which causes difficulty in procurement and management of waterproof rubber sleeve ring materials, and the corresponding procurement cost is higher. At the same time, after the basement bottom plate cushion layer is poured, it is difficult to achieve complete surface flatness, and after the waterproof rubber sleeve ring is installed, the gap between the waterproof rubber sleeve ring and the coiled material makes it difficult to play a good sealing role, and there is a water seepage risk, therefore, we propose a kind of anti-floating anchor rod end waterproof structure.

[0019] EMBODIMENT

[0020] Please refer to Figs. 1-3In this embodiment of the utility model, a waterproof structure for the end of an anti-buoyancy anchor rod includes an installation sleeve 1. A plurality of telescopic rods 2 are evenly arranged on the inner wall of the installation sleeve. A limiting block 4 is provided at the end of the telescopic arm of each telescopic rod 2. A plurality of anchor rod reinforcing bars 5 are also evenly arranged inside the installation sleeve 1. The inner wall of the limiting block 4 contacts the anchor rod reinforcing bars 5. Under the action of the limiting block 4, the installation quality of the anchor rod reinforcing bars 5 is ensured, thereby guaranteeing the quality of the anti-buoyancy anchor rod to a certain extent. A return spring 3 is sleeved on the outer side of each telescopic rod 2. One end of the return spring 3 is connected to the inner wall of the installation sleeve 1, and the other end is connected to the limiting block 4. Under the action of the return spring 3, the installation quality of the anchor rod reinforcing bars 5 by the limiting block 4 is ensured. The anchor rod reinforcing bars 5 are connected by a fixed welded pipe, thereby ensuring the quality of the anti-buoyancy anchor rod.

[0021] An anchor rod body 6 is provided at the bottom of the installation sleeve 1, and the anchor rod body 6 is connected to the base plate 10. Under the action of the anchor rod body 6, the anti-buoyancy anchor rod can be better connected to the base plate 10, thereby ensuring the installation quality of the anti-buoyancy anchor rod. A corrugated pipe collar 7 is also provided at the top of the installation sleeve 1. The corrugated pipe collar 7 is filled with micro-expansion waterproof mortar. Under the action of the micro-expansion waterproof mortar, not only is the connection quality between the anchor rod steel bar 5 and the corrugated pipe collar 7 guaranteed, but the waterproof quality of the anti-buoyancy anchor rod is also improved. Under the action of the corrugated pipe collar 7, it is convenient to connect the anchor rod steel bar 5 to the outside, thereby ensuring the efficiency of the anti-buoyancy anchor rod.

[0022] The corrugated pipe collar 7 is provided with a first waterproof layer 8. Under the action of the first waterproof layer 8, the anti-buoyancy anchor rod can play a certain waterproof role. A second waterproof layer 9 is also provided on the outside of the first waterproof layer 8. Under the action of the second waterproof layer 9, the waterproof performance of the anti-buoyancy anchor rod is further improved.

[0023] The base plate 10 is a cement-based penetrating crystalline layer. Cement-based penetrating crystalline silicone ions diffuse into the concrete along with the surface water, and react chemically with calcium ions in the concrete to generate water-insoluble calcium silicate hydrate. The crystals fill the capillary pores and bond with the concrete to form a whole, blocking the capillary channels inside the concrete, thereby making the concrete dense and preventing water leakage. Moreover, once it comes into contact with water, it can continuously produce chemical reactions, and the generated crystals continue to grow and fill the capillary pores inside the concrete. Therefore, even if the concrete structure is locally damaged and leaks, it will crystallize and repair itself after encountering water.

[0024] In actual use, clean the anti-buoyancy anchor rods thoroughly, pour the basement floor slab cushion layer, break the cement slurry at the anchor rod ends to make them flush with the cushion layer, and clean the ends again; apply cement-based penetrating crystalline waterproof coating to the anchor rod ends, and extend 100mm outward from the anchor rod ends towards the cushion layer to form a circular waterproof layer; lay waterproof membrane, and cut circular holes in the membrane at the anchor rod ends according to the diameter of the anchor rod body to ensure that the membrane can fit into the anchor rod body; use corrugated pipes of the same diameter as the anti-buoyancy anchor rods, cut rings according to the thickness requirements of the bottom reinforcement protective layer of the basement floor slab and the flatness of the cushion layer, and fit them into the anchor rod body; after positioning, fill with micro-expansion waterproof mortar, compact, and seal. By implementing the above steps, the waterproof construction of the anti-buoyancy anchor rod ends is completed. After the micro-expansion waterproof mortar has solidified, the subsequent construction of the basement floor slab can proceed.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
