Description

Technical Field

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

[0002] An anchor bolt is a component used to reinforce soil and rock masses, mainly composed of a free section and an anchored section. One end of the anchor bolt is connected to the engineering structure, while the other end extends into the ground. Prestressing is applied to enhance the stability of the soil and rock mass. Anchor bolts are not only used in mines but also widely applied in engineering technologies such as slope, tunnel, and dam reinforcement. The free section is the area that transmits the tensile force at the anchor head to the anchor body; its function is to apply prestress to the anchor bolt. The anchored section is the area where cement grout bonds the prestressing tendons to the soil layer; its function is to increase the bonding friction between the anchor body and the soil layer, increase the bearing capacity of the anchor body, and transmit the tensile force of the free section deep into the soil.

[0003] When using existing anchor bolts for support, they are prone to floating and deformation when subjected to excessive or uneven radial pressure, affecting the anchoring effect. Therefore, this does not meet the current requirements. To address this, we propose an anti-buoyancy anchor bolt with a reinforced structure. Utility Model Content

[0004] The purpose of this invention is to provide an anti-buoyancy anchor rod with a reinforced structure to solve the problem mentioned in the background art that when existing anchor rods are used for support, they are prone to floating and deformation when subjected to excessive or uneven radial pressure, thus affecting the anchoring effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-buoyancy anchor rod with a reinforced structure, comprising a rod body, a grouting ring fixedly installed on the outer side of the upper end of the rod body, a sealing arc seat rotatably connected to the upper end face of the grouting ring, multiple grouting holes provided on the upper end faces of both the grouting ring and the sealing arc seat, multiple reinforcing rings installed below the grouting ring on the outer side of the rod body, multiple connectors installed on the outer side of each reinforcing ring, a reinforcing sleeve fixedly installed on the outer side of the bottom end of the rod body, multiple annular unfolding units installed on the outer side of the reinforcing sleeve, and a conical plug installed at the bottom end of the reinforcing sleeve.

[0006] Preferably, the upper end of the rod is rotatably connected to the sealing arc seat, the grouting ring and the multiple grouting holes on the upper end face of the sealing arc seat are coaxial, the diameter of the grouting ring is the same as that of the reinforcing sleeve, and a grouting cavity is provided between the reinforcing sleeve and the grouting ring on the outside of the rod.

[0007] Preferably, the plurality of reinforcing rings are disposed inside the grouting cavity, the rod body is fixedly connected to the plurality of linearly arranged reinforcing rings, and the plurality of connectors are arranged circumferentially relative to the axis of the reinforcing rings.

[0008] Preferably, the annular unfolding unit consists of a positioning ring and multiple swing rods. The multiple swing rods are arranged circumferentially relative to the axis of the positioning ring. A torsion spring is provided between the positioning ring and the bottom end of the multiple swing rods. The positioning ring and the swing rods are rotatably connected by the torsion springs.

[0009] Preferably, the bottom end of the rod passes through a reinforcing sleeve and is fixedly connected to a conical plug, and the plurality of the annular unfolding units are arranged linearly along the axis of the reinforcing sleeve.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses the same diameter of the grouting ring and the reinforcing sleeve to form a grouting cavity in the middle of the rod body between the reinforcing sleeve and the grouting ring in the soil layer. Multiple reinforcing rings fixedly fitted on the outside of the rod body are linearly arranged inside the grouting cavity. Grouting holes are provided on the upper end face of the grouting ring and the sealing arc seat, so that grouting is performed in the grouting cavity through the grouting holes to form a grouting layer. After grouting is completed, the sealing arc seat is rotated so that the grouting holes on the grouting ring and the sealing arc seat are staggered. The sealing arc seat facilitates the sealing of the grouting ring and maintains the stability of the grout. Multiple reinforcing rings and multiple connectors on the reinforcing rings can fully contact the grouting layer, thereby improving the stable connection between the rod body and the grouting layer. Furthermore, the reinforcing sleeve and the grouting layer can maintain the anchoring effect of the rod body and effectively avoid floating and deformation due to radial force. 2. In this invention, the positioning rings and swing rods in multiple linearly arranged annular unfolding units are connected by torsion springs. Under the torque of the torsion springs, the multiple swing rods unfold outward relative to the axis of the positioning rings. The swing rods on the positioning rings in the multiple annular unfolding units provide reverse support for the offset of the rod body, effectively maintaining the anchoring strength of the rod body.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Please see Figure 1 and Figure 2 This utility model provides an embodiment of an anti-buoyancy anchor rod with a reinforced structure, comprising a rod body 1, a grouting ring 4 fixedly installed on the outer side of the upper end of the rod body 1, a sealing arc seat 5 rotatably connected to the upper end face of the grouting ring 4, and multiple grouting holes 6 provided on the upper end faces of both the grouting ring 4 and the sealing arc seat 5. The upper end of the rod body 1 is rotatably connected to the sealing arc seat 5, and the multiple grouting holes 6 provided on the upper end faces of the grouting ring 4 and the sealing arc seat 5 are coaxial. A reinforcing sleeve 2 is fixedly installed on the outer side of the bottom end of the rod body 1. The diameter of the grouting ring 4 and the reinforcing sleeve 2 are the same. A grouting cavity is provided between the reinforcing sleeve 2 and the grouting ring 4 on the outer side of the rod body 1. Grouting is performed in the grouting cavity through the grouting holes 6 to form a grouting layer. After grouting is completed, the sealing arc seat 5 is rotated so that the grouting holes 6 on the grouting ring 4 and the sealing arc seat 5 are misaligned, thereby facilitating the sealing of the grouting ring 4 through the sealing arc seat 5 and maintaining the stability of the grout.

[0015] Please see Figures 1 to 3 Multiple annular unfolding units 7 are installed on the outer side of the reinforcing sleeve 2. The multiple annular unfolding units 7 are linearly arranged along the axis of the reinforcing sleeve 2. The annular unfolding unit 7 consists of a positioning ring 701 and multiple swing rods 702. The multiple swing rods 702 are arranged in a circle relative to the axis of the positioning ring 701. A torsion spring is provided between the bottom end of the positioning ring 701 and the multiple swing rods 702. The positioning ring 701 and the swing rods 702 are rotatably connected by the torsion spring. The multiple swing rods 702 are in an outward unfolding state relative to the axis of the positioning ring 701. Then, the swing rods 702 on the positioning ring 701 in the multiple annular unfolding units 7 provide reverse support for the offset of the rod 1.

[0016] Please see Figure 1 and Figure 3 A tapered plug 8 is installed at the bottom end of the reinforcing sleeve 2. The bottom end of the rod 1 passes through the reinforcing sleeve 2 and is fixedly connected to the tapered plug 8. Multiple reinforcing rings 3 are installed below the grouting ring 4 on the outside of the rod 1. Multiple connectors 9 are installed on the outside of each reinforcing ring 3. The multiple reinforcing rings 3 are located inside the grouting cavity. The rod 1 is fixedly connected to the multiple linearly arranged reinforcing rings 3. The multiple connectors 9 are arranged circumferentially relative to the axis of the reinforcing rings 3. Through the multiple reinforcing rings 3 and the multiple connectors 9 on the reinforcing rings 3, the rod 1 can fully contact the grouting layer, thereby improving the stable connection between the rod 1 and the grouting layer. Thus, the reinforcing sleeve 2 and the grouting layer can maintain the anchoring effect of the rod 1.

[0017] In summary, when using anchor bolts for support, the bottom end of the rod 1 is inserted through the reinforcing sleeve 2 and fixedly connected to the conical plug 8, so that the rod 1 synchronously drives the conical plug 8, the reinforcing sleeve 2, the reinforcing ring 3 and the grouting ring 4 to be inserted into the soil layer in sequence. The diameter of the grouting ring 4 is the same as that of the reinforcing sleeve 2, so that the middle part of the rod 1 and the soil layer between the reinforcing sleeve 2 and the grouting ring 4 form a grouting cavity. Multiple reinforcing rings 3 fixedly fitted on the outside of the rod 1 are arranged linearly on the inside of the grouting cavity. Grouting holes 6 are provided on the upper end face of the grouting ring 4 and the sealing arc seat 5, so that grouting operation is performed in the grouting cavity through the grouting holes 6 to form a grouting layer. After grouting is completed, the sealing arc seat 5 is rotated so that the grouting ring 4 and the grouting hole 6 on the sealing arc seat 5 are misaligned. This allows the sealing arc seat 5 to easily seal the grouting ring 4 and maintain the stability of the grout. Multiple reinforcing rings 3 and multiple connectors 9 on the reinforcing rings 3 can fully contact the grouting layer, thereby improving the stable connection between the rod body 1 and the grouting layer. Furthermore, the reinforcing sleeve 2 and the grouting layer can maintain the anchoring effect of the rod body 1 and effectively prevent floating and deformation caused by radial force. When the rod 1 is subjected to axial pressure, the positioning rings 701 and the swing rods 702 in the multiple linearly arranged annular expansion units 7 are connected by torsion springs. Under the torque of the torsion springs, the multiple swing rods 702 are in an outward expansion state relative to the axis of the positioning rings 701. In turn, the swing rods 702 on the positioning rings 701 in the multiple annular expansion units 7 provide reverse support for the offset of the rod 1, effectively maintaining the anchoring strength of the rod 1.
