Landscape guardrail is one of the most common landscape guardrails in the city. It is an essential safety measure to ensure the driving safety of people and vehicles and prevent falling or collision. It is also a part close to pedestrians. The shape design of landscape guardrail will directly affect the beauty of the bridge. Landscape guardrail style is rich, mainly divided into four types, fence type, fence board, lattice format and mixed type. In the design of landscape fence, we should pay attention to the following two points:
1、 The scale of landscape fence. This is a very important point, because the most important role of railings is to ensure the safety of people and vehicles. If there is no sense of security, there will be no sense of beauty. Therefore, this requires that the landscape fence must be strong enough to withstand congestion and collision, and bring a sense of security and dependability to people.
Another point is that the height of the railing should not be too high to hinder people's vision. The height of the railing can be determined according to the water outlet distance of the bridge deck. Generally, when the clearance distance is more than three meters, the hand support surface of the railing is about one meter. When the clearance distance is less than three meters, the height of the railing can be appropriately reduced.
For a wide bridge deck, the height and end face size of railings can be slightly larger to increase the sense of stability of landscape guardrails.
2、 The diversity and unity of styles. At present, the design of landscape guardrail is mainly based on simple and lively style, but the pattern modeling of the components of the railing can be flexible and changeable, which can not only avoid monotony, but also maintain the harmony and unity of the railing, without affecting the main body of the bridge.
