Viaducts blooming all year round
What is the three-dimensional greening of viaduct guardrail?
Based on the original guardrail, combined with plant containers, three-dimensional greening was carried out on the top or bottom, one side or both sides of the guardrail.
In fact, many problems may appear in the three-dimensional greening project of viaduct. Take the green flower box of viaduct as an example
1. The hanging plastic container for greening is easy to be aged in the outdoor sun and rain, with poor safety and short service life;
2. Plastic and glass fiber reinforced plastic containers are heavy in weight, poor in heat resistance, large in thermal expansion rate, easy to burn and produce toxic gases when burning;
3. The container itself has no water storage function. The water, soil and fertilizer are stored for a short time and are easy to be lost;
At the same time, there are many problems in the fixed structure of the green flower box with viaduct: the exposed structure of the fixed structure is large, easy to rust and not beautiful. The container and structure are lack of fixed parts, the wind in the factory is strong, it is easy to move, and there are safety risks; the overall steel consumption is large, and there are a lot of solder joints.
Therefore, the three-dimensional green flower box design of viaduct should be considered from the combination of safety and functionality.
Because viaduct involves different slopes, the current technical specifications also put forward clear requirements for different grades of water supply system. If the inclined road surface is particularly prone to ponding, the water volume must be controlled. In places where it is difficult to digest, water will be released more slowly. In this way, the overflow situation can be effectively solved.
Which aspects are used to design the three-dimensional greening of viaduct?
First of all, the safety design of viaduct green box should consider the weight of greening equipment must be light, and the connection with viaduct should be firm and easy to overhaul. Therefore, it is necessary to customize the professional fixing method and steel structure design.
Secondly, the function design of viaduct green box should consider the need of providing plant growth environment and saving maintenance cost. It's not only short-lived and beautiful to plant, but also short-lived. Sustainability and ecological impacts.
Generally, the viaduct green box should have the following characteristics:
First of all, the breakthrough fixed system can be easily installed and disassembled without any mechanical equipment, thus reducing the construction difficulty and overall cost.
Secondly, the use of standardized stainless steel or plastic parts, no need for field welding, no risk of rust, solve the high construction costs and safety risks;
Thirdly, the integration of water and fertilizer and the standardization of pipeline and pipeline installation have solved the construction difficulties and overall beauty.
Fourth, the breakthrough structural design of the container solves the following problems:
1. Rainwater collection and reuse function to solve the phenomenon of water leakage and overflow, and realize the concept of ecological construction;
2. Ensure that there is no dead corner for watering and fertilizing, form natural transpiration, plant growth is uniform, and maintain a good growth pattern;
3. It can slow down the heat transfer, warm in winter and cool in summer, protect the healthy growth of plants and reduce the maintenance cost.
5. Combining with lighting function, it can decorate and beautify the city, and improve the safety of driving at night;
Sixth, intelligent water and fertilizer system, LED lighting control system, optional remote Wi Fi control system to reduce maintenance costs.
Recently, the "garden" of viaduct is in full bloom with "Fenghua rose" and "yellow hat", so you can pay more attention to the beautiful scenery on the side of the viaduct. With this standard, I believe that in the future, the maintenance of flowers will be more systematic and professional. At the same time, Baozhen green station also said that it will continue to improve the design of flowers and green plants, so that the viaduct greening will become the unique charm of Baozhen city landscape.
