Anchor cable device

Abstract

The utility model provides an anchor cable device, which relates to the technical field of engineering construction equipment and comprises a free section, an anchoring section, a wiring ring and a water swelling rubber gasket, and the water swelling rubber gasket is positioned on one side, close to the anchoring section, of the wiring ring at the joint of the free section and the anchoring section of an anchor cable body. And the water-swelling rubber gasket is provided with an exhaust hole, a grouting hole and a steel strand hole which correspond to the wiring ring. The length of the free section of the anchor cable can be effectively controlled, after grout is injected into the anchor cable body and makes contact with the water-swelling rubber gasket at the joint of the anchoring section and the free section, the water-swelling rubber gasket automatically swells to seal the exhaust hole and nearby gaps after meeting water, grouting pressure is obviously increased, grouting can be stopped, and the grouting efficiency is improved. At the moment, the grout is always located at the anchoring section and cannot flow into the free section, the length of the free section of the bonded pre-stressed anchor cable is guaranteed, therefore, external force is better applied to the steel strand in the free section, and then the pre-stress index of the anchor cable meets the design requirement.

Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction equipment, in particular to an anchor cable device. Background Art

[0002] The anchoring section of the bonded prestressed anchor cable is easily affected by geology, groundwater, grouting volume, etc. during the grouting process. The anchoring length is uncontrollable during construction, and slurry often enters the free section, which can easily lead to insufficient free section length or no free section, making it inconvenient to apply external force to the steel strands in the free section. This will result in the prestressing being unable to meet the design requirements. In the case of deformation of the anchor, shrinkage of the prestressed tendons, and deformation caused by external forces, the prestressing loss is large, resulting in a decrease in structural strength.

[0003] Therefore, there is an urgent need for an anchor cable device to solve the problem that the anchoring section length of the existing bonded prestressed anchor cable is uncontrollable, which easily leads to insufficient or no free section length, making the prestress application unable to meet the design requirements. Utility Model Content

[0004] The utility model provides an anchor cable device, which solves the problem that the anchoring section length of the existing bonded prestressed anchor cable is uncontrollable, which easily leads to insufficient free section length or no free section, and the prestressing cannot meet the design requirements.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An anchor cable device, comprising:

[0007] An anchor cable body, the anchor cable body comprising a free section and an anchoring section, and the anchor cable body can be placed in the anchor cable hole;

[0008] A wire-hanging ring, wherein a plurality of wire-hanging rings are provided, and the plurality of wire-hanging rings are respectively provided on the anchor cable body and at the junction of the free section and the anchor section and on the anchor section, and are used to evenly distribute the steel strands on the anchor cable body, so that the steel strands are located in the middle of the anchor cable hole when installed; the wire-hanging ring is provided with an exhaust hole, a grouting hole and a steel strand hole;

[0009] A water-swellable rubber gasket is located at a side of a wire ring at a junction of a free section and an anchoring section of the anchor cable body close to the anchoring section, and the water-swellable rubber gasket is provided with exhaust holes, grouting holes and steel strand holes corresponding to the wire ring.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0011] During actual use, the utility model can effectively control the length of the free section of the anchor cable. When the slurry is injected into the anchor cable body and contacts the water-swellable rubber gasket at the junction of the anchor section and the free section, the water-swellable rubber gasket automatically expands and closes the exhaust hole and nearby gaps after coming into contact with water. The grouting pressure is significantly increased, and the grouting can be stopped. At this time, the slurry is always in the anchor section and will not flow into the free section, thereby ensuring the free section length of the bonded prestressed anchor cable, thereby better applying external force to the steel strands in the free section, and then the prestress index of the anchor cable meets the design requirements.

[0017] The utility model is described in detail below in conjunction with the accompanying drawings.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] This embodiment provides an anchor cable device, such as Figure 1-Figure 3 As shown, including:

[0020] Anchor cable body, the anchor cable body comprises a free section 201 and an anchoring section 202, and the anchor cable body can be placed in the anchor cable hole 1;

[0021] A wire-hanging ring 3, wherein a plurality of wire-hanging rings 3 are provided, and the plurality of wire-hanging rings 3 are respectively provided on the anchor cable body and at the junction of the free section 201 and the anchor section 202 and on the anchor section 202, and are used to evenly distribute the steel strands on the anchor cable body, so that the steel strands are located in the middle of the anchor cable hole 1 when being installed; the wire-hanging ring 3 is provided with an exhaust hole, a grouting hole and a steel strand hole;

[0022] The water-swellable rubber gasket 4 is located at the side of the cable ring 3 at the junction of the free section 201 and the anchor section 202 of the anchor cable body, close to the anchor section 202. The water-swellable rubber gasket 4 is provided with an exhaust hole 5, a grouting hole 6 and a steel strand hole 7 corresponding to the cable ring 3.

[0023] During actual use, when the grouting reaches the expansion rubber gasket 4, the expansion rubber gasket 4 expands and seals the vent hole 5 and the gap at the end of the anchor section 202. Once the vent hole and the gap are sealed, the grouting pressure increases significantly, and the grouting length is calculated based on the grouting amount to meet the requirements and the grouting can be ended. In this way, excess slurry will not flow into the free section 201 of the anchor body during the grouting process, effectively solving the problem of the prestress not meeting the design requirements due to the insufficient length of the free section 201 of the anchor with bonding prestress.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
