DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0025] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment one:

[0027] Reference Figure 1-5 A soil nail combination connection structure includes a soil nail body 14, a first positioning plate 1 and a second positioning plate 2. The top surface of the first positioning plate 1 is provided with a lubricating oil hole 3, and the inner surface of the lubricating oil hole 3 is installed with a sealing plug 5. The center of the first positioning plate 1 is provided with a soil nail positioning hole 4. The bottom of the first positioning plate 1 is provided with a second positioning plate 2. The surface of the second positioning plate 2 is provided with a mounting threaded hole 6. The top of the second positioning plate 2 is provided with a first spring bellows 9. The middle surface of the second positioning plate 2 is provided with a second spring bellows 10. The mounting bracket is passed through the soil nail positioning hole 4. When connected with other equipment, the second spring bellows 10 at the bottom of the first positioning plate 1 and the first spring bellows 9 installed on the surface of the shock-absorbing guide rod 11 will bear the load on the mounting bracket and play a shock-absorbing effect. The top baffle 12 fixedly connected to the top surface of the shock-absorbing guide rod 11 can prevent the first positioning plate 1 from detaching from the shock-absorbing guide rod 11. The shock-absorbing guide rod 11 enables the mounting bracket to move vertically when subjected to load, so that the first spring bellows 9 and the second spring bellows 10 are fully compressed and can be lubricated from the lubricating oil hole 3 located on the top of the first positioning plate 1 Pour the lubricating oil into the oil sealing cavity 13 inside the shaft seat 1. The lubricating oil in the oil sealing cavity 13 can realize real-time lubrication of the soil nail positioning hole 4 in the middle of the first positioning plate 1, reducing manual workload. The pressure sensor 8 located between the second positioning plate 2 and the first spring bellows 9 can detect the pressure borne by the mounting bracket in real time. When the pressure borne by the mounting bracket exceeds the range, because the pressure sensor 8 is electrically connected to the threaded pressure gauge 7, the threaded pressure gauge 7 has a built-in whistle component, and the whistle component includes a controller and a buzzer electrically connected to the controller. The pressure sensor 8 is electrically connected to the threaded pressure gauge 7. When the data collected by the pressure sensor 8 is abnormal, the user can be notified by the built-in whistle component of the threaded pressure gauge 7, thereby avoiding the mounting bracket from being used beyond the load for a long time, which can increase the service life of the mounting bracket. The threaded pressure gauge 7 between the threaded holes 6 on the surface of the second positioning plate 2 can detect the pressure in the mounting threaded hole 6. When the bolt in the mounting threaded hole 6 is loose, the mounting threaded hole 6 can remind the user through the whistle component after detecting it. Specific embodiment two:

[0029] Reference Figure 1-5 , a rubber pad can be installed on the bottom surface of the first positioning plate 1. When the load borne by the shock-absorbing mounting bracket is very large, it is difficult for the first spring bellows 9 and the second spring bellows 10 alone to withstand the load, and after bearing the load, the first spring bellows 9 and the second spring bellows 10 will be severely damaged and it will be difficult to continue to play a shock-absorbing role. Therefore, a rubber pad of a certain thickness can be installed on the bottom surface of the first positioning plate 1. When facing general loads, the first spring bellows 9 on the surface of the shock-absorbing guide rod 11 and the second spring bellows 10 on the top surface of the second positioning plate 2 can buffer part of the pressure. When the load is large, after the first spring bellows 9 and the second spring bellows 10 bear the load, the rubber pad with a certain thickness installed on the bottom surface of the first positioning plate 1 can withstand the impact of the large load and relieve the pressure, thereby playing a shock-absorbing role, avoiding damage to the mounting bracket, and improving the service life of the mounting bracket. Specific embodiment three:

[0031] Based on the technical solution of the specific embodiment 1, the following content is further disclosed. When further work is carried out, the soil nail body 14 is inserted into the corresponding soil nail positioning hole 4. The inner wall of the soil nail positioning hole 4 is embedded with a rubber ring, which can further clamp the soil nail body 14. Then, the entire connection structure is nailed to the corresponding soil wall position. Then, the connection structure at the adjacent position is directly fixed through the guide positioning rod 15. The fixing method can be direct welding or bolted positioning. The adjacent connection structures can be connected together. If an uneven soil wall surface is encountered, some elastic rods or metal rods can be used to weld the adjacent connection structures together. In this way, when carrying a large load or encountering an unexpected load, the soil nails at adjacent positions can simultaneously provide load-bearing force to disperse the bearing capacity of the soil nails in a single area, thereby making the load-bearing capacity of the entire geowall stronger. Even if a part of the cost is increased, the overall safety is greatly improved, and the occurrence of geowall collapse and the like is basically eliminated, ensuring the absolute safety of construction.

[0032] It should be noted that the electronic products in this connection structure all use an external power supply (battery. If it needs to be reused, a device can be used to convert the mains power into low voltage for power supply). The power supply uses an Arduino circuit board for programming or a power chip to directly distribute power. The cost of the Arduino circuit board is relatively high, while the power chip only needs to realize the simplest circuit on and off, and the cost is extremely low. The power is distributed to the corresponding electronic components such as the buzzer without the need for complex control.

[0033] In summary:

[0034] The soil nail assembly connection structure primarily consists of a first positioning plate and a second positioning plate. The top surface of the first positioning plate features a lubrication hole for lubricating internal components, and a sealing plug is installed on its inner surface to prevent lubricant leakage. A soil nail positioning hole is located in the center of the first positioning plate for precise positioning of the soil nail and connection to other equipment. The bottom of the first positioning plate is fixedly connected to the second positioning plate to ensure the stability of the overall structure.

[0035] The second positioning plate is equipped with multiple threaded mounting holes on its surface, facilitating secure connection to the bracket or other components. A first spring bellows is mounted on the top of the second positioning plate. This bellows effectively absorbs impact and reduces vibration during load-bearing, ensuring smooth operation of the mounting bracket under load. A second spring bellows is also located in the middle of the second positioning plate to further enhance the shock absorption effect.

[0036] The shock-absorbing guide rod is connected to the second spring bellows at the bottom of the first positioning plate, providing both load-bearing and shock-absorbing functions. The mounting bracket connects to other equipment through the soil nail positioning holes. The second spring bellows at the bottom of the first positioning plate and the first spring bellows jointly bear the load applied by the mounting bracket and effectively reduce vibration. A baffle fixed to the top of the shock-absorbing guide rod prevents the first positioning plate from detaching from the shock-absorbing guide rod, ensuring overall structural stability.

[0037] The lubrication system injects lubricating oil into the seal cavity through a lubrication hole located at the top of the first positioning plate. This ensures real-time lubrication of the soil nail positioning holes, significantly reducing manual maintenance workload. A pressure sensor located between the second positioning plate and the first spring bellows monitors the pressure applied to the mounting bracket in real time. If the pressure exceeds a safe range, the pressure sensor activates a built-in alarm component through an electrical connection to the threaded pressure gauge, sounding an alarm to ensure safe operation.

[0038] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
