Description

Technical Field

[0001] This utility model relates to the field of buried pipeline protection technology, specifically a vibration reduction protection device to mitigate the impact of tunnel blasting construction on buried pipelines. Background Technology

[0002] Tunnel blasting is a method of excavating tunnels using controlled blasting technology. It is mainly used in underground engineering construction in fields such as transportation (railways, highways), water conservancy, and mining. Its core is to use the explosive energy of explosives to break up rock masses, and to ensure construction safety, efficiency, and quality through scientific design.

[0003] During tunnel blasting, the explosion of explosives generates vibrations and shock waves. These vibrations and shock waves propagate through the surrounding rock and soil to the buried pipeline, causing significant vibrations, displacement, or deformation of the pipeline and resulting in damage. Therefore, vibration reduction and protection devices are needed to protect the pipeline from vibration.

[0004] However, most existing methods of protecting buried pipelines involve wrapping the outside of the pipeline with vibration-damping material. But shock waves and vibrations can propagate to the buried pipeline through the surrounding soil and rock. Wrapping the pipeline with vibration-damping material alone is not effective in reducing vibration, which can easily lead to breakage at the welded joints and deformation of the pipeline.

[0005] Based on this, a vibration reduction and protection device is now provided to mitigate the impact of tunnel blasting on buried pipelines, which can eliminate the drawbacks of existing devices. Utility Model Content

An anti-corrosion and wear-resistant layer is installed on the top of the rubber pad.

[0025] In one embodiment, such as Figures 1-4 As shown, a vibration reduction and protection device for mitigating the impact of tunnel blasting construction on buried pipelines includes a lower clamping groove 1, with lower connecting plates 11 installed on the top of both sides of the lower clamping groove 1, and connecting bolts 12 threadedly connected to the inside of the lower connecting plates 11.

[0026] A vibration damping component is slidably connected inside the lower clamping groove 1. The vibration damping component includes a lower rubber groove 13, which is slidably connected inside the lower clamping groove 1. A lower rubber plate 14 is installed inside the lower rubber groove 13, and a lower silicone groove 15 is installed inside the lower rubber plate 14.

[0028] In this embodiment, the lower clamping groove 1 and the upper clamping groove 21 are connected by the connecting bolt 12 and the threaded connection between the lower connecting plate 11 and the upper connecting plate 2, so that the lower silicone groove 15 and the upper silicone groove 24 clamp the pipe body 112. The rubber material of the lower rubber plate 14 and the upper rubber plate 23 supports the lower silicone groove 15 and the upper silicone groove 24, and their deformation plays a role in buffering and vibration reduction.

[0029] In one embodiment, such as Figure 1 and Figure 2As shown, the lower connecting groove 16 clamps and connects the pipe body 112.

[0030] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the clamping assembly includes an upper connecting plate 2, which is threadedly connected to the upper half of the connecting bolt 12. An upper clamping groove 21 is installed between the two upper connecting plates 2. An upper rubber groove 22 is slidably connected inside the upper clamping groove 21. An upper rubber plate 23 is installed inside the upper rubber groove 22. An upper silicone groove 24 is installed inside the upper rubber plate 23. Two upper connecting grooves 25 are installed on both sides of the upper silicone groove 24. The clamping assembly, the lower clamping groove 1, and the vibration damping assembly inside them work together to clamp and buffer the pipe body 112 for protection.

[0031] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, both the lower connecting groove 16 and the upper connecting groove 25 are fitted with wrapping components, which wrap the outside of the pipe body 112.

[0032] In one embodiment, such as Figure 1-4 As shown, the wrapping assembly includes a first splicing groove 3, which is fitted into the lower connecting groove 16 and the upper connecting groove 25. A rubber pad 31 is installed on one side of the first splicing groove 3, and a second splicing groove 32 is installed on one side of the rubber pad 31. An anti-corrosion and wear-resistant layer 33 is installed on the top of the rubber pad 31. By using the two wrapping assemblies together, the upper and lower sides of the pipe body 112 are clamped and wrapped. The device is installed by the fitting connection between the first splicing groove 3 and the lower connecting groove 16 and the upper connecting groove 25, and by the fitting connection between the second splicing groove 32 and the lower connecting groove 16 and the upper connecting groove 25 of another device.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, a buffer assembly is installed at the bottom of the lower clamping groove 1 to dampen the bottom of the device.

[0034] In one embodiment, such as Figure 1 and Figure 2As shown, the buffer assembly includes a vibration damper 17, which is installed at the bottom of the lower clamping groove 1. A support plate 18 is installed at the bottom of the vibration damper 17, a rubber block 19 is installed at the bottom of the support plate 18, and a base plate 110 is installed at the bottom of the rubber block 19. Mounting rivets 111 are slidably connected around the base plate 110. The base plate 110 is installed by the mounting rivets 111. The rubber block 19 buffers the horizontal vibration of the device, and the vibration damper 17 buffers the vertical vibration, thereby improving the vibration reduction and protection effect of the device.

[0035] The above embodiment discloses a vibration reduction and protection device for mitigating the impact of tunnel blasting construction on buried pipelines. The device involves wrapping the lower part of the pipeline body 112 with a lower silicone groove 15, inserting mounting rivets 111 through the perimeter of a base plate 110 into the ground to fix the base plate 110, and using threaded connections between connecting bolts 12 and the lower connecting plate 11 and upper connecting plate 2 to wrap and clamp the outer side of the pipeline body 112. The lower silicone groove 15 and upper silicone groove 24 adhere to the pipeline body 112, thus buffering vibration. The rubber material of the upper rubber plate 23 and lower rubber plate 14 deforms and bends during vibration, facilitating vibration absorption and buffering, thereby improving the vibration reduction and protection effect of the device. The sliding connection between the upper rubber groove 22 and the upper clamping groove 21, and the sliding connection between the lower clamping groove 1 and the lower rubber groove 13 further enhance the device's vibration reduction and protection effect. The device features a dynamic connection, facilitating the replacement of its internal structure and improving its convenience. It connects to the first splicing groove 3 via the lower connecting groove 16 and the upper connecting groove 25, enabling the installation of the wrapping components. The cooperation of the upper and lower wrapping components wraps the outside of the pipe body 112, enhancing its vibration damping protection. The rubber pad 31 absorbs impact forces and is protected by an anti-corrosion and wear-resistant layer 33. It connects to the other side via the second splicing groove 32, facilitating the connection of multiple devices. The vibration damper 17 buffers vertical impact forces and vibrations, while the rubber block 19 at the bottom of the support plate 18 buffers lateral swaying, further improving the device's vibration damping protection and preventing damage to buried pipelines caused by shock waves and vibrations during tunnel blasting.
