Description

Technical Field

[0001] This utility model relates to the field of anti-buoyancy anchor technology, specifically to a composite waterproof structure for anti-buoyancy anchors. Background Technology

[0002] In underground structures of building engineering, in order to resist the buoyancy caused by the rise of groundwater level and resist the upward displacement of the building, anti-buoyancy anchors (also called anti-buoyancy piles) are usually used as anti-buoyancy measures for underground structures to ensure the safety and stability of the building.

[0003] The existing technology, such as the waterproof structure of the anti-buoyancy anchor rod with application number "202123363915.3", uses two opposing clamping plates to clamp the anti-buoyancy anchor rod, and fixes the two clamping plates relative to each other with fasteners. The clamping block is inserted into the groove of the clamping plate, and the clamping plate limits the clamping block, reducing the shaking of the anti-buoyancy anchor rod, thereby reducing the cracking of the waterproof coating and the occurrence of water seepage. However, in actual use, the above technical solution uses clamping plates to limit the movement of the floating anchor rods. However, since the anchor rods are supported by support rods located within the waterproof area, they cause greater damage to the waterproof structure when deformation occurs.

[0004] Therefore, a composite waterproof structure for anti-buoyancy anchors is proposed. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a composite waterproof structure for anti-buoyancy anchor bolts.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A composite waterproof structure for anti-buoyancy anchors includes an anchor head embedded in a base layer and an anti-buoyancy anchor fixedly connected thereto. A stabilizing member and a multi-layer waterproofing assembly are sequentially fitted onto the body of the anti-buoyancy anchor. The stabilizing member includes a radial support mechanism to improve the structural stability of the anti-buoyancy anchor and prevent cracking of the waterproofing assembly. An annular waterproofing plate is welded to the top of the anti-buoyancy anchor for axial positioning of the stabilizing member. A concrete protective layer is poured on top of the waterproofing assembly, and a water-swellable sealant is applied to the anchor head between the concrete protective layer and the waterproofing plate to form a double-sealed structure.

[0007] Furthermore, the radial support mechanism consists of a support frame sleeved around the anti-buoyancy anchor rod, four sets of support rods radially hinged to the circumference of the support frame, and a planar connecting seat hinged to the outer end of each support rod. The inner cavity of the support frame is filled with a high-strength concrete stabilizing layer to form an integral support system.

[0008] Furthermore, the waterproof component is a multi-layer composite structure, comprising, from bottom to top, a cement-penetrating crystalline waterproof coating bonded to the substrate, a first layer of waterproof coating applied thereon, a fully covered waterproof membrane, an annular waterproof rubber collar fitted onto the anti-buoyancy anchor, a second layer of waterproof coating applied inside the waterproof rubber collar, and a waterproof membrane reinforcement layer covering the top.

[0009] Furthermore, the waterproof rubber collar forms an interference fit with the anti-buoyancy anchor rod, and its inner cavity is filled with the second layer of waterproof coating to achieve interface sealing.

[0010] Furthermore, both the cement-penetrating crystalline waterproof coating and the waterproof membrane reinforcement layer have a stepped cross-section, forming an interlocking waterproof interface.

[0011] Furthermore, both the first and second waterproof coatings are made of non-curing waterproof asphalt materials with excellent high-temperature stability.

[0012] The beneficial effects of this utility model are as follows: This invention uses a radial support mechanism consisting of a support frame and radial support rods to distribute the stress on the anchor rods, avoiding local stress concentration that could lead to cracking of the waterproof layer. At the same time, the multi-layer waterproof component uses cement-penetrating crystalline waterproof coating, non-curing waterproof asphalt layer, waterproof membrane, and stepped interlocking structure to form a composite seal. Combined with the axial limiting of the annular waterproof board and the double protection of water-swellable sealing adhesive, it not only improves the stability of the anti-buoyancy anchor rods but also effectively reduces the damage to the waterproof system caused by structural deformation, significantly enhancing the overall waterproof durability.

[0019] like Figure 1-6As shown, a composite waterproof structure for anti-buoyancy anchors includes an anchor head 2 pre-embedded in a base layer 1 and an anti-buoyancy anchor 201 fixedly connected thereto. A stabilizing member 3 and a multi-layer waterproof component 5 are sequentially fitted onto the body of the anti-buoyancy anchor 201. The stabilizing member 3 includes a radial support mechanism to improve the structural stability of the anti-buoyancy anchor 201 and prevent cracking of the waterproof component 5. An annular waterproof plate 6 is welded to the top of the anti-buoyancy anchor 201 to axially limit the stabilizing member 3. The design of the annular waterproof plate 6 prevents the stabilizing member 3 from shifting or loosening during use, ensuring its stability and reliability. A support frame 301 is fitted around the outer periphery of the anti-buoyancy anchor 201, serving to fix and support it. The support rod 303 is radially hinged to the support frame 301 around the perimeter, extends outward and is hinged to the planar connecting seat 304 to form a three-dimensional support system. This structure can effectively disperse the external force on the anti-buoyancy anchor rod 201, improve its structural stability, and prevent the anti-buoyancy anchor rod 201 from deforming or being damaged due to external forces during construction or use. This also prevents the waterproof component 5 from cracking due to uneven stress. Because the support rod 303 has a large support range, it can avoid damage to the waterproof component 5. The top of the waterproof component 5 is filled with a concrete protective layer 4, and the anchor pile head 2 between the concrete protective layer 4 and the waterproof board 6 is covered with water-swellable sealing glue 7 to form a double sealing structure.

[0020] like Figure 6 As shown, the radial support mechanism consists of a support frame 301 sleeved around the anti-buoyancy anchor rod 201, four sets of support rods 303 radially hinged to the circumference of the support frame 301, and a planar connecting seat 304 hinged to the outer end of each support rod 303. The inner cavity of the support frame 301 is filled with a high-strength concrete stabilizing layer 302 to form an integral support system. Specifically, the concrete has high compressive strength and can form a solid support system together with the support frame 301, support rods 303, and other components to ensure the stability of the anti-buoyancy anchor rod 201 during use and provide reliable protection for the waterproof component 5. The connecting seat 304 has a through hole, which can be fixed by using anchor bolts or limit bolts to limit the position of the support frame 301.

[0021] like Figure 2-5As shown, the waterproof component 5 is a multi-layer composite structure, comprising, from bottom to top, a cement-penetrating crystalline waterproof coating 501 bonded to the base layer 1, a first waterproof coating 502 applied thereon, a fully covered waterproof membrane 503, an annular waterproof rubber collar 505 fitted onto the anti-buoyancy anchor 201, a second waterproof coating 504 coated inside the waterproof rubber collar 505, and a waterproof membrane reinforcement layer 506 covering the top. Specifically, the cement-penetrating crystalline waterproof coating, as the bottom layer of the waterproof component 5, is tightly bonded to the base layer 1. It is a new type of waterproof material that works by penetrating into the capillaries and cracks inside the concrete to form crystals, blocking seepage channels and achieving a waterproof effect. This coating has strong adhesion to the base layer 1 and can effectively prevent groundwater from seeping upwards from the base layer 1. The waterproof membrane is a common waterproof material with good flexibility and waterproof performance, effectively preventing water penetration. Its combination with the non-curing waterproof asphalt layer further enhances the overall performance of the waterproof layer.

[0022] like Figure 2-4 As shown, the waterproof rubber collar 505 and the anti-buoyancy anchor rod 201 form an interference fit, and the inner cavity is filled with a second layer of waterproof coating 504 to achieve interface sealing; specifically, the annular waterproof rubber collar 505 is sleeved on the anti-buoyancy anchor rod 201 and forms an interference fit with the anti-buoyancy anchor rod 201. This design can ensure that the waterproof rubber collar 505 and the anti-buoyancy anchor rod 201 are tightly fitted.

[0023] like Figure 4 As shown, the cross-sections of both the cement-penetrating crystalline waterproof coating 501 and the waterproof membrane reinforcement layer 506 are stepped, forming an interlocking waterproof interface. Specifically, the cross-sections of both the waterproof membrane reinforcement layer 506 and the cement-penetrating crystalline waterproof coating 501 are stepped, forming an interlocking waterproof interface. This design can further enhance the integrity and sealing of the waterproof layer and prevent moisture from penetrating from the edges of the waterproof layer.

[0024] like Figure 4 As shown, both the first waterproof coating 502 and the second waterproof coating 504 are made of non-curing waterproof asphalt material with excellent high-temperature stability. Specifically, the non-curing waterproof asphalt material has good adhesion and waterproof properties, and can form a good bond with the cement penetrating crystallizing waterproof coating. It has excellent high-temperature stability and will not flow or deform even in high-temperature environments, ensuring the durability of waterproof performance.

[0025] In summary: This anti-buoyancy anchor composite waterproof structure uses pre-embedded anchor pile heads 2 and anti-buoyancy anchors 201 as its foundation. It utilizes stabilizing components 3, including a support frame 301, radial support rods 303, and a concrete stabilizing layer 302, fitted onto the rod body to disperse external forces and enhance structural stability. The multi-layer waterproof component 5, from bottom to top, employs cement-penetrating crystalline waterproof coating 501, a non-curing waterproof asphalt layer, waterproof membrane 503, an interference-fit waterproof rubber collar 505, and a stepped interlocking reinforcing layer to form multiple seals. Combined with the top concrete protective layer 4 and water-swellable sealing adhesive 7, it achieves double sealing. The annular waterproof membrane 6 is an axially limiting stabilizing component. The entire structure, through the synergistic effect of rigid support and flexible waterproof materials, effectively resists groundwater buoyancy and prevents leakage.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
