Description

Technical Field

[0001] The utility model relates to the technical field of anti - floating anchor rods, and particularly to an anti - floating fixed - diameter anchor head that overcomes the problem. Background Technique

[0002] An anti - floating anchor rod is an anchoring structure used in underground engineering to resist the buoyancy of groundwater. It usually consists of steel bars, prestress, enlarged anchor heads, etc. Its main function is to resist the floating of the structure through the frictional resistance between the anchor rod and the foundation soil when the groundwater level rises, ensuring the safety and stability of the structure. In order to prevent possible deformation, displacement and other problems of the anchor rod during construction and use, and ensure that the anchor rod can effectively overcome the buoyancy in various environments and maintain the stability of the structure, here, the utility model proposes an anti - floating fixed - diameter anchor head that overcomes the problem.

[0003] According to the search, the Chinese patent document, publication number: CN209114516U, discloses an external anchor head and its connecting piece of an anti - floating self - locking anchor rod. By setting a top steel backing plate, a bottom steel backing plate and several stiffening plates, the contact area with the ground is increased, and it can bear large - tonnage prestress; at the same time, the anchor head has high strength, is not easy to deform and bend, has good durability, the construction process is simple and convenient, saving a large amount of manpower and material resources. However, in the actual use process of this device, the anchor head cannot generate frictional force or biting action with the soil body or rock, so the anchor rod cannot bear a large tensile force, thus reducing its anti - floating effect; in addition, when filling the filling material, this device can only fill the voids in the anchor rod hole to form a preliminary anchor body, but after the filling material such as cement slurry initially solidifies, it will shrink to form new voids, and there may be defects such as cracks in the construction process, reducing the anti - pulling force and stability of the anchor rod.

[0005] Aiming at the deficiencies of the prior art, the utility model provides an anti - floating fixed - diameter anchor head that overcomes the problem, which has the advantages of stable structure, simple operation, effectively improving the anti - floating force and stability of the device, and solves the above - mentioned technical problems.

[0006] (2) Technical Solutions

[0007] To achieve the above purpose, the utility model provides the following technical solution: an anti - floating fixed - diameter anchor head that overcomes the problem, including an anchor rod body, an anchor fixture is fixedly installed on the bottom surface of the anchor rod body, an anchor head is fixedly installed at the bottom of the anchor fixture, a groove is opened on the outer side surface of the anchor fixture, a baffle is installed inside the groove, a spring, a telescopic stabilizing rod and a first limiting sleeve are fixedly installed on the inner side surface of the baffle, a limiting rod is installed inside the first limiting sleeve, a second limiting sleeve is fixedly installed on the outer side surface of the anchor rod body, and a grouting pipe is installed inside the second limiting sleeve.

[0008] Preferably, the number of the grooves and the baffles is three each, the number of the springs and the telescopic stabilizer bars is multiple, and one ends of the springs and the telescopic stabilizer bars away from the baffles are connected to the inside of the grooves.

[0009] Through the above technical solution, when inserting components such as the anchor rod body and the anchor fittings into the inside of the anchor rod hole, the three baffles can be abutted against the soil body or rock under the reaction force of multiple springs respectively. Therefore, the friction between the device and the inside of the anchor rod hole can be effectively increased. At the same time, multiple telescopic stabilizer bars can enhance the stability between the baffle and the anchor fittings, further improving the overall anti-floating effect.

[0010] Preferably, a plurality of limiting guide rails are arranged inside the groove, a plurality of limiting grooves are arranged on the outer side surface of the baffle, and the limiting guide rails are correspondingly installed inside the limiting grooves.

[0011] Through the above technical solution, when installing the baffle inside the groove or removing the baffle from the groove, the multiple limiting guide rails can effectively limit the position of the baffle to prevent its position from shifting and other situations. At the same time, it is also convenient for the staff to install it before operation, improving the overall stability and convenience of the device.

[0012] Preferably, the number of the first limiting sleeves is multiple, the number of the limiting rods is three, and three limiting holes are respectively formed on the top surface of the anchor fitting and inside the groove, and the limiting rods are correspondingly inserted into the limiting holes.

[0013] Through the above technical solution, when installing the baffle, push it into the inside of the groove and compress the multiple springs, and then insert the limiting rods into the limiting holes and the first limiting sleeves correspondingly to fix the position of the baffle. Additionally, when the whole device is placed inside the anchor rod hole, the limiting rods can be pulled out from the top end. Therefore, the baffle can be abutted against the inside of the anchor rod hole under the reaction force of the springs, improving the overall stability and practicality of the device.

[0014] Preferably, the number of the anchor rod bodies is three.

[0015] Through the above technical solution, the material of the anchor rod body is usually selected as structures such as steel bars.

And it also simplifies the construction process, meeting the requirements of engineering design and application.

[0016] Preferably, the number of the second limiting sleeves is multiple, and the number of the grouting pipes is two.

This grouting is mainly to fill the voids inside the anchor hole and form a preliminary anchor body, ensuring good adhesion between the device and the surrounding soil, and laying a foundation for subsequent grouting. After the first grouting starts to set, connect the other grouting pipe to equipment such as a high-pressure grouting machine to perform secondary grouting on the anchor hole. By adopting the high-pressure grouting method, it is ensured that the grout can penetrate deep into the anchor hole and combine with the anchor body formed by the first grouting to form a more solid whole.

At the same time, multiple telescopic stabilizing rods can enhance the stability between the baffle plate and the anchor, further improving the overall anti-floating effect. Through multiple limiting guide rails, the position of the baffle plate can be effectively restricted to prevent its position from shifting, etc. At the same time, it is also convenient for the staff to install it before operation, improving the overall stability and convenience of the device.

[0026] Please refer to Figures 1-3 , a floating resistance fixed diameter anchor head, including an anchor rod body 1, an anchor fixture 2 is fixedly installed on the bottom surface of the anchor rod body 1, an anchoring head 3 is fixedly installed at the bottom of the anchor fixture 2, a groove 4 is opened on the outer side surface of the anchor fixture 2, a baffle 5 is installed inside the groove 4, a spring 6, a telescopic stabilizer bar 7 and a first limit sleeve 8 are fixedly installed on the inner side surface of the baffle 5, a limit rod 9 is installed inside the first limit sleeve 8, and a second limit sleeve 10 is fixedly installed on the outer side surface of the anchor rod body 1, and a grouting pipe 11 is installed inside the second limit sleeve 10.

[0027] Specifically, the number of the grooves 4 and the baffles 5 are both set to three, the number of the springs 6 and the telescopic stabilizer bars 7 are both set to be multiple, and one end of the springs 6 and the telescopic stabilizer bars 7 far away from the baffle 5 are both connected to the inside of the groove 4. The advantage is that when inserting components such as the anchor rod body 1 and the anchor fixture 2 into the anchor rod hole, the three baffles 5 can be abutted against the soil or rock under the reaction force of the multiple springs 6 respectively. Therefore, the friction between the device and the inside of the anchor rod hole can be effectively increased, and at the same time, the multiple telescopic stabilizer bars 7 can enhance the stability between the baffle 5 and the anchor fixture 2, further improving the overall anti-floating effect.

[0028] Specifically, a plurality of limiting guide rails 12 are arranged inside the groove 4, and a plurality of limiting grooves 13 are arranged on the outer side of the baffle 5, and the limiting guide rails 12 are correspondingly installed inside the limiting grooves 13. The advantage is that, through this structure, when the baffle 5 is installed inside the groove 4 or the baffle 5 is removed from the groove 4, the plurality of limiting guide rails 12 can effectively limit the position of the baffle 5 to prevent its position from being offset, etc., and it can also facilitate the staff to install it before the operation, thereby improving the overall stability and convenience of the device.

[0029] Specifically, the number of the first limiting sleeves 8 is multiple, the number of the limiting rods 9 is three, and the top surface of the anchor 2 and the inside of the groove 4 are each provided with three limiting holes 14, and the limiting rods 9 are correspondingly inserted into the inside of the limiting holes 14. The advantage is that, through this structure, when the baffle 5 is installed, it is pushed into the inside of the groove 4 and the multiple springs 6 are compressed, and then the limiting rods 9 are correspondingly inserted into the limiting holes 14 and the inside of the first limiting sleeve 8 to fix the position of the baffle 5; in addition, when the device is placed inside the anchor hole as a whole, the limiting rods 9 can be pulled out from the top, so that the baffle 5 can abut against the inside of the anchor hole under the reaction force of the springs 6, thereby improving the overall stability and practicality of the device.

[0030] Specifically, there are three anchor rod bodies 1. The advantage is that the material of the anchor rod body 1 is usually selected as a structure such as a steel bar, and the three anchor rod bodies 1 can not only improve the stability and bearing capacity of the structure, but also better distribute the force, so that the force of a single anchor rod body 1 is more balanced, and the construction process is simplified to meet the needs of engineering design and application.

[0031] Specifically, the number of the second limiting sleeves 10 is multiple, and the number of the grouting pipes 11 is two. The advantage is that the positions of the two grouting pipes 11 can be effectively limited and fixed by the multiple second limiting sleeves 10. When the device is placed inside the anchor hole as a whole, the anchor hole can be grouted by connecting one of the grouting pipes 11 to a grouting pump and other equipment. The grouting this time is mainly to fill the gap in the anchor hole and form a preliminary anchor body to ensure good bonding between the device and the surrounding soil, and lay the foundation for subsequent grouting; after the first grouting is initially set, another grouting pipe 11 is connected to a high-pressure grouting machine and other equipment to perform secondary grouting on the anchor hole.

Then, insert the limit rod 9 into the limit hole 14 and the first limit sleeve 8 correspondingly to fix the position of the baffle 5. After that, when the whole device is placed inside the anchor rod hole, the limit rod 9 can be pulled out from the top. Under the reaction force of the spring 6, the baffle 5 can abut against the soil or rock. Therefore, the friction between the device and the inside of the anchor rod hole can be effectively increased. At the same time, multiple telescopic stabilizing rods 7 can enhance the stability between the baffle 5 and the anchor 2, further improving the overall anti-floating effect. Through multiple limit guide rails 12, the position of the baffle 5 can be effectively restricted to prevent its position from shifting and other situations. At the same time, it is also convenient for the staff to install it before operation, improving the overall stability and convenience of the device. Through multiple second limit sleeves 10, the positions of the two grouting pipes 11 can be effectively restricted and fixed. When the whole device is placed inside the anchor rod hole, by connecting one of the grouting pipes 11 to equipment such as a grouting pump, the anchor rod hole can be grouted. This grouting is mainly to fill the voids in the anchor rod hole and form a preliminary anchor body to ensure good adhesion between the device and the surrounding soil and lay a foundation for subsequent grouting. After the first grouting starts to set, connect the other grouting pipe 11 to equipment such as a high-pressure grouting machine to perform secondary grouting on the anchor rod hole. By adopting the high-pressure grouting method, it is ensured that the grout can penetrate deep into the anchor rod hole and combine with the anchor body formed by the first grouting to form a more solid whole. Therefore, the anti-pulling force and stability of the device can be effectively improved.
