Description

Technical Field

[0001] This application relates to the field of pipeline protection technology, and in particular to a buried pipeline protection device. Background Technology

[0002] Buried pipelines are the "lifeline of the city," playing a vital role in people's daily lives. Water, oil, gas, electricity, and internet access are all transmitted through buried pipelines. These pipelines are typically laid in shallow soil layers, and various construction methods inevitably disturb the soil, causing heave, settlement, and lateral displacement. This can also cause deformation of nearby existing buried pipelines. After road construction, due to the creep effect of the foundation soil, under the long-term action of its own weight and traffic loads, the foundation soil will undergo slow creep deformation and be squeezed out to both sides, further deforming the buried pipelines. Damage to the pipelines will seriously affect roadbed safety and social production. The impact of soil deformation on buried pipelines is mainly reflected in two aspects: First, excessive deformation of the surrounding soil causes excessive deformation of the pipeline, resulting in loss of transmission function; second, the stress on the pipeline exceeds the design stress value of the pipeline material due to soil compression, leading to localized cracking.

[0003] Traditional buried pipeline protection measures mainly rely on digging protective trenches around the pipeline, backfilling with sand and gravel, or setting up rigid retaining walls. However, these methods have problems such as high construction difficulty, high cost, and limited protection effect. Especially under complex geological conditions, these traditional measures often fail to achieve the ideal protection effect, and the risk of pipeline damage due to soil deformation remains high.

[0004] Therefore, this application provides a buried pipeline protection device. Utility Model Content

It aims to solve the problem that traditional buried pipeline protection measures mainly rely on digging protective trenches around the pipeline, backfilling with sand and gravel, or setting up rigid retaining walls. However, these methods have problems such as high construction difficulty, high cost, and limited protection effect. Especially under complex geological conditions, these traditional measures often fail to achieve the ideal protection effect, and the risk of pipeline damage due to soil deformation remains high.

[0006] To achieve the above objectives, this application provides the following technical solution: a buried pipeline protection device, comprising a main frame, a composite buffer layer disposed inside the main frame, an installation hole being provided in the middle of the composite buffer layer, the composite buffer layer comprising a high-density polyurethane foam base layer located inside the main frame, the high-density polyurethane foam base layer being wrapped with a latex layer, the latex layer being wrapped with a wear-resistant rubber layer, support units disposed on both sides of the composite buffer layer, the support units comprising several sets of hydraulic rods, the several sets of hydraulic rods being fixedly installed on both sides of the composite buffer layer, and the telescopic ends of the several sets of hydraulic rods being installed on the inner wall of the main frame.

[0007] By adopting the above technical solution, the pipeline is installed inside the main frame through mounting holes. When the pipeline is affected by soil deformation, the wear-resistant rubber layer first absorbs the impact energy. Due to its excellent resilience, the wear-resistant rubber layer can effectively reduce the direct impact of soil deformation on the pipeline. Then, the latex layer further enhances the buffering effect of the composite buffer layer. Finally, the wear-resistant rubber layer enhances the elasticity of the composite buffer layer. At the same time, the wear-resistant rubber layer also provides additional wear resistance and tear protection. The hydraulic rod can automatically adjust its extension length according to the soil deformation to maintain the stable position of the pipeline. Through the composite buffer layer and support unit, it effectively copes with different types of soil deformation, enhances the adaptability and reliability of the device, effectively reduces the direct impact of soil deformation on the pipeline, and improves the safety and stability of the pipeline.

[0009] By adopting the above technical solution, the fixing holes facilitate the insertion of rods and other components to firmly embed the main frame into the soil, and the perforations facilitate the installation of pipelines, thus improving its practicality during use. The sealing cover separates the main frame from the external soil and moisture, reducing the erosion and damage of the composite buffer layer, support unit and pipelines caused by the external soil and moisture, which helps to extend the service life.

[0010] As a preferred technical solution of this application, a number of first reinforcing ribs are fixedly installed at the upper end of the main frame, and a number of second reinforcing ribs are fixedly installed at the lower end of the main frame.

[0011] By adopting the above technical solution, the structural strength of the main frame is enhanced through the design of the first and second reinforcing ribs, making it more stable and reliable, and improving the deformation resistance of the main frame.

[0012] As a preferred technical solution of this application, the front surface of the sealing cover is provided with two sets of ventilation holes, and the two sets of ventilation holes are respectively located on both sides of the perforation.

[0013] By adopting the above technical solution, ventilation holes ensure air circulation inside the main frame, preventing wiring problems caused by excessive temperature and improving safety during use.

[0014] As a preferred technical solution of this application, a filter screen is fixedly installed on the front surface of the sealing cover at both sets of ventilation holes.

[0015] By adopting the above technical solution, the filter screen can block external impurities, insects, etc. from entering the main frame without affecting ventilation at the ventilation holes, thus maintaining the cleanliness and safety of the main frame.

[0016] As a preferred technical solution of this application, the outer surfaces of several sets of hydraulic rods are coated with an anti-corrosion coating.

[0017] By adopting the above technical solution, the impact of moisture on the hydraulic rod is reduced through the anti-corrosion coating, which helps to improve the corrosion resistance of the hydraulic rod and extend its service life.

[0018] As a preferred embodiment of this application, the number of hydraulic rods is at least 12 sets.

[0019] By adopting the above technical solution, with at least 12 sets of hydraulic rods, the stability and reliability of the support unit are ensured, enabling it to adapt to strong soil deformation pressure.

[0020] The beneficial effects of this application are:

[0021] 1. The pipeline is installed inside the main frame through mounting holes. When the pipeline is affected by soil deformation, the wear-resistant rubber layer first absorbs the impact energy. Due to its excellent resilience, the wear-resistant rubber layer can effectively reduce the direct impact of soil deformation on the pipeline. Then, the latex layer further enhances the buffering effect of the composite buffer layer. Finally, the wear-resistant rubber layer enhances the elasticity of the composite buffer layer and provides additional wear resistance and tear protection.
