Description

Technical Field

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

[0002] CN220166997U discloses a waterproof structure for the root of an anti-buoyancy anchor, comprising a concrete layer with a waterproof membrane laid on top. This invention allows for the pre-laying of the waterproof membrane at the anti-buoyancy anchor location, marking the anchor's position, cutting a hole, and inserting the membrane into the anchor from top to bottom. The position of the waterproof membrane at the root is adjusted to ensure even distribution between the pre-drilled hole and the anchor. A water-swellable sealing ring is used around the anchor, and its lower part is secured to the waterproof membrane with double-sided butadiene tape. An adhesive layer is then filled into the water-swellable sealing ring, with the adhesive layer height preferably lower than the sealing ring. After filling, the coating is allowed to cure naturally. The water-swellable sealing ring adheres firmly and tightly to the waterproof membrane, and the non-oil-permeable creep rubber waterproof coating exhibits good durability, effectively preventing water seepage at the membrane bonding point.

[0003] While this waterproofing structure for the root of an anti-buoyancy anchor bolt offers excellent waterproofing and durability, its drawbacks are also more pronounced. For example, it solves the leakage problem at the root of traditional anchor bolts through multiple layers of protection, including anti-corrosion layers, metal water-stop rings, and rust-proof layers. It combines rigid and flexible waterproofing characteristics, is easy to construct, and highly durable, making it suitable for various underground anti-buoyancy projects. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a waterproof structure for the root of anti-buoyancy anchor bolts. This structure, through multiple layers of protection including an anti-corrosion layer, a metal water-stop ring, and a rust-proof layer, solves the leakage problem at the root of traditional anchor bolts. It combines rigid and flexible waterproofing characteristics, is easy to construct, and boasts high durability, making it suitable for various underground anti-buoyancy projects.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof structure at the root of an anti-buoyancy anchor rod, comprising an anchor rod, wherein an anti-corrosion layer for increasing corrosion resistance is attached to the outer surface of the anchor rod, a waterproof membrane is fixedly connected to the bottom of the anti-corrosion layer, a protective component is provided at the bottom of the waterproof membrane, a segmented rod is fixedly connected to the bottom of the anchor rod, a fixing rod is fixedly connected to one side of the outer surface of the segmented rod, and reinforcing rods are fixedly connected to the top of the fixing rod in a circular array at equal intervals.

[0006] In one specific embodiment, the protective component includes a metal water-stop ring welded to the other side of the anchor bolt surface. The top of the metal water-stop ring is provided with an anti-rust layer, and a waterproof coating is fixedly connected to the other side of the anchor bolt surface. The protective component improves the water seepage prevention of the anchor bolt.

[0007] In one specific embodiment, an expansion waterstop is wound around the other end of the anchor rod, and an anti-oxidation sleeve for increasing anti-oxidation properties is fitted on the other side of the expansion waterstop surface. With the installation of the expansion waterstop, when the anchor rod leaks water, the expansion waterstop expands upon contact with water, thereby stopping the water source and improving the waterproofness of the anchor rod.

[0008] In one specific embodiment, a cross groove is provided at the center of the other end of the anchor rod, and the inner wall of the cross groove is coated with a waterproof coating. The cross groove improves the toughness of the anchor rod and prevents it from breaking.

[0009] In one specific embodiment, the top of the anchor rod is provided with a cavity, and a grouting pipe is provided inside the cavity. The structural design of the grouting pipe facilitates the later grouting and repair of the bottom of the anchor rod.

[0010] In one specific embodiment, a plug is threaded to the bottom of the grouting pipe, and an anti-slip film is attached to the outer surface of the plug to increase its anti-slip properties. The plug facilitates the subsequent opening of the grouting pipe by personnel.

[0011] In one specific embodiment, the outer surface of the anchor rod is covered with reinforcing ribs to increase toughness, and the outer surface of the reinforcing ribs is covered with an anti-oxidation film. The anti-oxidation properties of the reinforcing ribs are improved through the combined use of the anti-oxidation films.

[0012] Compared with the prior art, this utility model provides a waterproof structure for the root of an anti-buoyancy anchor bolt, which has the following beneficial effects:

[0013] In the technical solution disclosed in this utility model, the protective components, anchor bolts, and waterproof membrane are used in combination. When personnel use the anchor bolts, the waterproof membrane and metal water-stop ring can isolate the source of water seepage when the anchor bolts are leaking, thereby improving the waterproof effect of the anchor bolts and increasing their service life.

[0014] The other end of the anchor rod provided by this utility model is wrapped with an expansion waterstop. An anti-oxidation sleeve for increasing anti-oxidation properties is sleeved on the other side of the expansion waterstop. A cavity is opened at the top of the anchor rod, and a grouting pipe is installed inside the cavity. When the anchor rod needs to be repaired, the personnel can unscrew the plug to open the grouting pipe. Then, the maintenance personnel can place the output end of the grouting equipment at one end of the grouting pipe and then put the repair liquid inside the anchor rod, thereby playing a role in the subsequent maintenance of the anchor rod.
