How do stone columns of safety protection facilities enhance their protective effect through unique structural design?
Publish Time: 2025-02-11
Stone columns of safety protection facilities play an important protective role in public places such as urban roads, bridges, and parks. Through unique structural design, these stone columns can significantly enhance their protective effect while ensuring beauty and durability.
1. Material selection
Highly weather-resistant materials: Select high-quality stones such as granite and marble, which have high weather resistance and corrosion resistance and can maintain performance for a long time in various weather and environments.
Composite materials: Some stone columns use composite materials, such as adding steel bars or fiber reinforcements inside the stone to increase its strength and toughness.
2. Shape design
Cylindrical: When a cylindrical stone column is hit, it can evenly disperse the impact force, reduce the risk of excessive local force, and improve the protective effect.
Polygonal: Polygonal stone columns (such as hexagons, octagons, etc.) can provide stronger protection in certain directions while maintaining a certain aesthetics.
Conical or stepped: Conical or stepped stone columns can guide vehicles or pedestrians to gradually slow down when hit, reduce impact force and improve safety.
3. Size and weight
Reasonable height: The height of the stone column should be designed reasonably, which can effectively prevent pedestrians and small vehicles from passing through, but not too high to affect the sight and appearance.
Appropriate diameter: The diameter of the stone column should be moderate. If the diameter is too small, it is easy to break, and if the diameter is too large, it will affect the appearance and space utilization.
Increase weight: By increasing the weight of the stone column, its stability can be improved and the risk of being easily moved can be reduced. For example, heavy materials such as concrete or metal can be added to the base.
4. Foundation design
Deep foundation: The foundation of the stone column should be buried deep underground to increase its stability and impact resistance. Usually the foundation depth should exceed one-third of the height of the stone column.
Reinforcement measures: Use concrete or other reinforcement materials to wrap around the foundation of the stone column to improve the strength and stability of the foundation.
Connection method: Ensure that the connection between the stone column and the foundation is firm. Pre-buried steel bars, anchors and other connection methods can be used to prevent the stone column from loosening or collapsing when impacted.
5. Surface treatment
Smooth surface: The smooth surface can reduce the friction of pedestrians or vehicles during collision and reduce the risk of injury.
Anti-slip treatment: Anti-slip treatment is performed on the upper part of the stone column or the part that pedestrians can touch to increase safety.
6. Structural optimization
Internal structure: The interior of the stone column can be designed as a hollow or filled structure. The hollow structure can reduce weight and reduce costs, and the filled structure (such as filled concrete) can increase strength and stability.
Modular design: The modular design can facilitate the installation and maintenance of the stone column. The modularly designed stone column can be spliced and combined to form a continuous protective facility to enhance the overall protective effect.
7. Shape and layout
Interval setting: Reasonable setting of the spacing between the stone columns can effectively separate and protect, and will not be too crowded to affect the appearance and traffic.
Curved design: In curved sections or intersections, stone columns can be designed into curved shapes to better adapt to the curve of the road and improve the protection effect.
Segmented design: In longer protective facilities, stone columns can be designed in segments, and each segment is fixed by connectors to enhance the overall stability and protection ability.
Through material selection, shape design, size and weight, foundation design, surface treatment, structural optimization, shape and layout, intelligent design, and the combination of aesthetics and function, safety protection facilities stone columns can significantly enhance their protection effect while maintaining beauty and durability. These design points not only improve the safety performance of stone columns, but also optimize the overall quality of the urban environment and the happiness of residents.
