Description

Technical Field

[0001] The utility model relates to the technical field of ground anchors, in particular to an embedded anchor rod assembly. Background Art

[0002] As a key engineering structural element, embedded anchor bolts play an important role in the reinforcement and enhancement of geotechnical engineering structures such as deep foundation pits and tunnels. It interacts with the soil through cohesion and friction. When subjected to load or force, it transfers force to the soil using prestress or anchoring force, thereby providing the necessary support and stability.

[0003] During the construction process, it is crucial to select the appropriate anchor type and specifications. Subsequently, the drilling tool is used to perform precise drilling operations at the predetermined location, and the anchor is inserted into the hole to ensure that it is accurately positioned and firmly fixed. After that, the grouting operation will ensure that the anchor is closely integrated with the surrounding rock and soil, further enhancing its anchoring effect.

[0004] However, embedded anchors also have some potential problems. First, larger holes will reduce the contact area between the anchor and the surrounding rock and soil, thereby reducing friction and adhesion, and thus affecting its stability. Second, holes that are too large may destroy the original structure of the rock and soil, reduce its overall strength, and may even cause safety hazards such as collapse or landslides. In addition, since the side rods of embedded anchors are fixed, their adaptability is relatively limited. When the geological conditions are complex or change greatly, they may not be able to effectively cope with the deformation and displacement of the rock and soil, resulting in a decrease in stability performance. Utility Model Content

[0005] The main purpose of the utility model is to provide an embedded anchor rod assembly, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] An embedded anchor rod assembly comprises an outer sleeve, a lateral anchor rod and a drill rod, the side wall of the outer sleeve is provided with a plurality of notches, the lateral anchor rod is installed at the notches of the outer sleeve through a connector, the upper end opening of the outer sleeve is a threaded opening, a connecting stud is connected through the threaded opening, a handle and a base rod are respectively provided at the upper and lower ends of the connecting stud, and the lower end of the base rod is connected to the drill rod, and the drill rod is drilled into the ground;

[0008] The side wall of the base rod is provided with a side hole, and the upper end of the side hole is connected to an arc-shaped elastic strip, the free end of the arc-shaped elastic strip is a tightening strip, the base rod is rotated downward and presses against the lateral anchor rod through the arc-shaped elastic strip and the tightening strip, the lateral anchor rod extends out to form an angle with the outer sleeve, and the outer sleeve and the base rod are stabilized underground by the lateral anchor rod.

[0009] As a further preferred embodiment of the present invention, a hanging hole is provided on the end surface of the handle, and a rope is inserted into the hanging hole;

[0010] As a further preferred embodiment of the present invention, a plurality of the notches are evenly distributed on the outer sleeve, and each group of notches is opposite to each other;

[0011] As a further preferred embodiment of the present invention, the lateral anchor rod and the connector are designed as one piece, and the cross-sections of the connector and the lateral anchor rod are designed in an "L" shape. The side wall of the connector is provided with a rotating shaft, which is inserted into the notch opening and connected to the outer sleeve.

[0012] As a further preferred embodiment of the present invention, the connecting stud, base rod, drill rod and handle are designed as one piece, and the connecting stud is threadably matched with the threaded opening, and the cross-section of the connecting stud and the base rod is designed in a "T" shape;

[0013] As a further preferred embodiment of the present invention, the arc-shaped elastic strip and the clamping strip are designed as one piece, and both are made of elastic metal material. The arc-shaped elastic strip is welded and fixed on the side hole of the base rod, and the clamping strip squeezes and pushes the lateral anchor rod and the connecting head to move outward.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, the arc-shaped elastic rod and the lateral anchor rod are combined to form a stable support system. When the base rod rotates downward, the arc-shaped elastic rod uses its excellent elastic properties to smoothly push the lateral anchor rod out, ensuring that it forms a stable angle with the outer sleeve and is firmly anchored in the soil or rock. This design enables the anchor rod assembly to effectively resist external forces, such as wind force, earthquake force, etc., thereby maintaining the stability and safety of the structure.

[0016] In addition, considering that the texture and strength of soil or rock may vary depending on the environment, a single anchor structure may be difficult to adapt to various complex geological conditions. However, the synergy of the arc-shaped elastic rod and the lateral anchor rod shows excellent flexibility and adaptability. The elasticity of the arc-shaped elastic rod can be customized according to actual needs to adapt to the hardness of different soils or rocks. At the same time, the extension length and angle of the lateral anchor rod can also be adjusted according to the specific situation to achieve the best fixing effect.

[0017] Compared with traditional anchor installation methods, the embedded anchor assembly is easier and faster to install. Operators only need to drill the assembly into the soil or rock, and then rotate the base rod to extend the lateral anchor rod without the need for additional fixing equipment or cumbersome steps. This efficient installation method not only saves time costs, but also reduces the skill requirements for operators.

[0018] Finally, the arc-shaped elastic rod and the lateral anchor rod together build a strong support network, which can jointly bear the external force, thereby significantly improving the bearing capacity of the entire anchor rod assembly. This makes the embedded anchor rod assembly more widely applicable in engineering applications such as bridges, tunnels, and building foundations, providing strong support guarantees for various projects.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 - Figure 4 As shown, an embedded anchor assembly is composed of multiple key components, including an outer sleeve 1, a lateral anchor 3, a drill rod 12 and a connector 4, etc. Each component has its unique function and role, and together they achieve a stable installation of the anchor assembly.

[0026] The outer sleeve 1 is the main part of the assembly, and a plurality of notches 2 are cleverly opened on its side wall. These notches 2 are evenly spaced, and each group of notches 2 is opposite to each other, providing an ideal position for the installation of the lateral anchor rods 3. The lateral anchor rods 3 are closely connected to the outer sleeve 1 through the connector 4. The connector 4 and the lateral anchor rod 3 are designed as an integral whole, and their cross-section is "L" shaped to ensure the stability of the connection. The side wall of the connector 4 is provided with a rotating shaft, which can be easily inserted into the opening of the notch 2 and reliably connected to the outer sleeve 1.

[0027] The upper opening of the outer sleeve 1 is designed as a threaded opening 5, which allows the connecting stud 7 to be easily connected to the outer sleeve 1. The upper and lower ends of the connecting stud 7 are respectively provided with a handle 6 and a base rod 8, and the handle 6 is convenient for the user to operate during the installation process. The lower end of the base rod 8 is connected to the drill rod 12, and the entire anchor assembly can be easily drilled into the ground by rotating and pushing the drill rod 12.

[0028] In order to further enhance the stability of the anchor rod assembly, a side hole 9 is provided on the side wall of the base rod 8. The upper end of the side hole 9 is connected with an arc-shaped elastic strip 10, and the free end of the arc-shaped elastic strip 10 is a tightening strip 11. When the base rod 8 is rotated downward, the arc-shaped elastic strip 10 and the tightening strip 11 will work together to press against the lateral anchor rod 3, so that it extends and forms a certain angle with the outer sleeve 1. In this way, the lateral anchor rod 3 can effectively stabilize the outer sleeve 1 and the base rod 8 in the ground to prevent them from loosening or shifting.

[0029] In order to facilitate carrying and transportation, a hanging hole 13 is further provided on the end surface of the handle 6, and the user can pass a rope through the hanging hole 13 to hang the anchor rod assembly at a suitable position.

[0030] The entire embedded anchor assembly is exquisitely designed and reasonably structured, which is not only easy to install, but also stable and reliable. Through the synergistic effect of various components, the anchor assembly can be effectively and firmly installed underground, providing a solid foundation for various projects.

[0031] Usage process: The entire embedded anchor assembly needs to be prepared. The assembly mainly includes key components such as outer sleeve 1, lateral anchor 3, drill rod 12 and connector 4. Make sure each component is intact so that the subsequent installation work can be carried out smoothly.

[0032] Next, we connect the lateral anchor rod 3 to the outer sleeve 1 through the connector 4. The side wall of the connector 4 is provided with a rotating shaft, which can be easily inserted into the opening of the notch 2 on the side wall of the outer sleeve 1. During the insertion process, it is necessary to ensure that the connection between the connector 4 and the outer sleeve 1 is firm and reliable to prevent loosening or falling off during the subsequent installation process.

[0033] Then, we connect the connecting stud 7 to the upper end of the outer sleeve 1 through the threaded opening 5. The upper and lower ends of the connecting stud 7 are respectively provided with a handle 6 and a base rod 8, which is convenient for us to operate. At this point, the entire anchor assembly has been preliminarily assembled.

[0034] Next, we use the drill rod 12 for installation. The drill rod 12 is connected to the lower end of the base rod 8, and then the entire anchor assembly is drilled into the ground by rotating and advancing the drill rod 12. During the drilling process, it is necessary to keep the drill rod 12 vertical and stable to ensure that the anchor assembly can enter the ground smoothly.

[0035] After the anchor rod assembly is drilled to a predetermined depth, we need to unfold the lateral anchor rod 3. At this time, by rotating the base rod 8, the base rod 8 is rotated downward. During the downward rotation of the base rod 8, the arc-shaped elastic strip 10 and the tightening strip 11 will work together to resist the lateral anchor rod 3, so that it extends and forms a certain angle with the outer sleeve 1. In this way, the lateral anchor rod 3 can effectively stabilize the outer sleeve 1 and the base rod 8 in the ground.

[0036] Finally, we need to fix and inspect the anchor rod assembly. Make sure that the lateral anchor rod 3 has been fully deployed and firmly fixed to the ground, and check whether the outer sleeve 1 and the connecting stud 7 are tightly connected and not loose. If necessary, a rope can be used to pass through the hanging hole 13 on the handle 6 to hang the anchor rod assembly in a suitable position for subsequent work.

[0037] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0038] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
