Description

Technical Field

[0001] This utility model relates to the field of power, communication, water supply and other line crossing technology, and in particular to a line protection device that can be directly laid on the road. Background Technology

[0002] Currently, power, communication, and water supply lines typically cross roads using the open-cut and buried method. This method has many drawbacks, such as traffic disruption, long construction periods, and severe road surface damage. Therefore, there is an urgent need for an innovative road crossing technology that can be deployed quickly, has a stable structure, and does not damage the road surface. Utility Model Content

[0003] The purpose of this utility model is to provide a line protection device that can be directly laid on the road, which effectively solves the problems of traffic interference and road surface damage caused by traditional excavation methods. The device has a reasonable structure, efficient installation, and strong load-bearing capacity, and is suitable for various road environments, especially for line protection needs under heavy traffic scenarios.

[0004] To achieve the above objectives, this utility model provides a road protection device that can be directly laid on roads, including a pipe body, modular connecting components, and an anchoring structure. The pipe body is designed with a flat bottom and an upper arc-shaped cross-section, and has an internal cavity for laying the line. An internal support structure is provided inside the cavity and welded to the pipe body. Several pipe bodies are detachably connected through the modular connecting components. The pipe body is fixedly connected to the roadbed through the anchoring structure. Both ends of the pipe body are provided with sealed end caps, which are connected to the pipe body by bolts.

[0005] Preferably, the internal support structure is made of H-beams or angle steel, and includes multiple sets of vertical steel supports and diagonal steel supports. The vertical steel supports are welded vertically to the top and bottom of the cavity, and the diagonal steel supports are welded to the top and bottom of the cavity, forming a triangular support structure with the vertical steel supports and the top wall of the cavity.

[0006] Preferably, the modular connection assembly includes a plug groove, a bolt hole, and a rubber gasket disposed in the bolt hole. Adjacent pipe bodies are fitted together through the plug groove and locked by bolts. A sealing strip is provided at the connection of the plug groove to enhance the connection sealing.

[0007] Preferably, the anchoring structure includes connectors and anchors disposed on both sides of the road. The connectors are fixedly connected to the main body of the pipeline and fixedly connected to the roadbed through the anchors.

[0008] Preferably, the sealed end is a flange end cover, the sealing surface of the flange end cover is provided with an annular groove, a rubber sealing ring is embedded in the annular groove, and the flange end cover is sealed to both ends of the pipe body by bolts to block rainwater and dust.

[0009] Preferably, the flat bottom of the pipe body is provided with anti-slip texture.

[0010] The beneficial effects of this utility model are as follows:

[0011] (1) The line protection device of this utility model adopts a flat bottom + semi-circular arc steel structure cross section design, which can effectively distribute vehicle load and enhance compressive strength and balance. The arched upper part resists vertical pressure through structural bending, while the flat bottom structure ensures the stability of placement and anti-slip performance, giving the device good structural stability;

[0012] (2) The vertical and diagonal steel supports installed inside the main body of the pipeline effectively prevent the top of the pipeline from sinking or the sidewall from deforming, greatly improving the stability and durability of the overall structure under long-term load, and can adapt to the environmental requirements of frequent traffic flow.

[0013] (3) Adopting a modular design concept, prefabricated standard sections can be produced in the factory and only need to be quickly assembled and connected on the construction site, which significantly shortens the construction cycle and reduces traffic interference, making it suitable for rapid construction tasks under high-density road networks in cities.

[0014] (4) The closed structure set at both ends of the main body of the pipeline can effectively block the influence of external factors such as rainwater and dust on the pipeline, and improve the safety and stability of the pipeline operation;

[0015] (5) The anchoring structures set at both ends of the road can prevent the main body of the pipeline from shifting due to factors such as temperature changes and traffic vibrations, ensuring that the main body of the pipeline is fixed in the designated position, enhancing its resistance to displacement and pull-out, and improving the overall safety performance of the system.

The pipe body 1 is designed with a flat bottom and an upper arc-shaped cross-section. The flat bottom and the upper arc-shaped steel structure of the pipe body 1 are integrally formed by rolling or welding to ensure uniform stress. The flat bottom design allows the pipe body 1 to be placed stably on the road surface, preventing rolling and ensuring uniform stress. The upper arc structure improves the resistance to external pressure through the arch effect and adapts to vehicle loads. It has a cavity for laying the line inside, and an internal support structure 4 is installed in the cavity. The internal support structure 4 is welded to the pipe body 1 to enhance the stability and load-bearing capacity of the arched part and prevent structural collapse or deformation. Several pipe bodies 1 are detachably connected by modular connecting components 5. The pipe body 1 is fixedly connected to the roadbed by the anchoring structure 3. Sealed end caps 2 are provided at both ends of the pipe body 1, and the sealed end caps 2 are connected to the pipe body 1 by bolts.

[0029] Figure 7 For the use of this device in heavy traffic sections, the arrow indicates the direction of traffic flow. For heavy traffic sections, the device also includes a solid filling structure 12, which is foamed lightweight soil or other fluid solidification material, used to fill the cavity to form a solid structure, thereby further improving the load-bearing capacity and rigidity of the main body of the pipeline 1 and ensuring its long-term safe operation under complex load conditions. After filling, both ends of the main body of the pipeline 1 are sealed to prevent material loss and maintain structural integrity.

[0030] The internal support structure 4 is made of H-beams or angle steel. The internal support structure 4 includes multiple sets of vertical steel supports 41 and diagonal steel supports 42. The vertical steel supports 41 are welded vertically to the top and bottom of the cavity, respectively. The diagonal steel supports 42 are welded to the top and bottom of the cavity, respectively. The diagonal steel supports 42, the vertical steel supports 41 and the top wall of the cavity form a triangular support structure.

[0031] The modular connection assembly 5 includes a plug groove 52, a bolt hole 51, and a rubber gasket set in the bolt hole 51. Adjacent pipe bodies 1 are fitted together through the plug groove 52 and locked by bolts. A sealing strip 6 is provided at the connection of the plug groove 52 to enhance the connection sealing.

[0032] Modular connection component 5 supports three assembly modes: ① flange bolt connection can be used for permanent use; ② interlocking groove 52 can be used for rapid construction; ③ welding can be used for high-strength requirements. The most suitable assembly mode can be selected according to the actual use situation.

[0033] Anchoring structures 3 are installed at both ends of the road to prevent displacement or slippage of the main pipe body 1 due to temperature changes, vehicle pressure, or other external forces. Anchoring structures 3 include connectors 32 and anchors 31 installed on both sides of the road. Connectors 32 are fixedly connected to the main pipe body 1 and to the roadbed via anchors 31. The sealed end 2 is a flange end cap. The sealing surface of the flange end cap has an annular groove 7, within which a rubber sealing ring 8 is embedded. The flange end cap is bolted to both ends of the main pipe body 1 for sealing, isolating the internal wiring system from the external environment and preventing debris and rainwater from entering. The flat bottom of the main pipe body 1 has anti-slip textures 9.

[0034] Therefore, this utility model provides a line protection device that can be directly laid on the road using the above-mentioned structure, which effectively solves the problems of traffic interference and road surface damage caused by traditional excavation methods. The device has a reasonable structure, is efficient to install, and has strong load-bearing capacity.
