Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to an existing basement steel strand anchor cable anti-buoyancy reinforcement sealing anchor seepage prevention device and seepage prevention anchor structure. Background Technology

[0002] With the increasing demand for underground space development, basement uplift accidents are occurring frequently. Currently, anti-buoyancy anchors are commonly used for reinforcement. However, when steel strands are used as anchor reinforcement, groundwater can seep into the basement structure through the gaps between the steel strands, affecting the normal use of the basement.

[0003] Based on the above problems, this application proposes an anti-buoyancy reinforcement and sealing anchor anti-seepage device for existing basement steel strand anchor cables. Utility Model Content

[0004] The purpose of this utility model is to provide an existing basement steel strand anchor cable anti-buoyancy reinforcement sealing anchor seepage prevention device and seepage prevention anchor structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An existing basement steel strand anchor cable anti-buoyancy reinforcement and sealing anti-seepage device includes an anchor plate, a steel pipe waterstop sleeve, a waterstop ring, and a waterproof cover. The steel pipe waterstop sleeve is fitted on the upper end of the anchor bolt bundle. There are one or more waterstop rings, which are set on the outer wall of the steel pipe waterstop sleeve. The anchor plate is set on the top of the steel pipe waterstop sleeve. The waterproof cover is set on the upper end of the anchor plate and covers the anchor bolt.

[0007] Furthermore, the water-stop ring is a reinforcing bar circumferentially welded to the outer wall of the water-stop sleeve of the steel pipe.

[0008] Furthermore, at least two water-stop rings are provided on the upper and lower outer walls of the steel pipe water-stop sleeve.

[0009] Furthermore, the waterproof cover is filled with waterproof grease.

[0010] This utility model also provides a seepage-proof anchor structure, including an anchor bundle, the upper end of which is provided with the existing basement steel strand anchor cable anti-buoyancy reinforcement sealing anchor seepage-proof device as described above.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1) The leakage problem at the anchorage of the post-installed anti-buoyancy anchor rod was solved.

[0013] 2) It solved the leakage problem caused by the gap between the bottom of the anti-buoyancy anchor plate and the foundation concrete. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 and Figure 2 An existing basement steel strand anchor cable anti-buoyancy reinforcement sealing and seepage prevention device includes an anchor plate 1, a steel pipe waterstop sleeve 2, a waterstop ring 3, and a waterproof cover 4. The steel pipe waterstop sleeve 2 is sleeved on the upper end of the anchor rod bundle 5. There are one or more waterstop rings 3, which are set on the outer wall of the steel pipe waterstop sleeve 2. The anchor plate 1 is set on the top of the steel pipe waterstop sleeve 2. The waterproof cover 4 is set on the upper end of the anchor plate 1 and covers the anchor rod 500.

[0019] Continue reading Figure 2 In one embodiment of this utility model, two water-stop rings 3 are provided on the outer wall of the steel pipe water-stop sleeve 2. The water-stop rings 3 are steel bars welded circumferentially to the outer wall of the steel pipe water-stop sleeve 2.

[0020] It should be noted that the number of the aforementioned water-stopping rings 3 can be adjusted as needed.

[0021] Continue reading Figure 2 In one embodiment of this utility model, the waterproof cover 4 is filled with waterproof grease 6, which is a known waterproof material and will not be described in detail.

[0022] Please see Figure 1 and Figure 2 This utility model also provides a seepage-proof anchor structure, including an anchor bundle 5, with the upper end of the anchor bundle 5 provided with the existing basement steel strand anchor cable anti-buoyancy reinforcement sealing anchor seepage-proof device as described above.

[0023] The specific implementation method of this utility model is as follows:

[0024] Step 1: Install a steel pipe waterstop sleeve 2 and a waterstop ring 3 at the connection between the anchor rod and the base plate 8;

[0025] Step 2: Weld and fix the steel pipe waterstop sleeve 2 to the anchor plate 1;

[0026] Step 3: After the steel strands are tensioned, install a waterproof cover and seal it with waterproof sealant.

[0027] Generally, there are two ways for anti-buoyancy anchor bolts to leak. The first way is that groundwater seeps along the steel strand protective sleeve from the anchor sealing point. This invention directly seals and prevents seepage by using a waterproof cover 4 and waterproof sealant 6. The second way is that gaps easily appear between the anchor plate and the basement floor slab due to the lack of integral casting, allowing groundwater to seep out from the bottom of the anchor plate 1 along the steel strand protective sleeve. This invention extends the leakage path by setting a steel pipe water-stop sleeve 2 and a water-stop ring 3, making the leakage path more than three times that of a typical anchor head, thus greatly reducing the probability of leakage. Furthermore, the steel pipe water-stop sleeve 2 and water-stop ring 3 are directly embedded in the anchor sealing concrete and cast as a single unit, eliminating gaps between the water-stop sleeve and the concrete, thereby achieving the purpose of seepage prevention.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
