In view of the environmental problems of highway construction, people have been exploring how to combine road construction with environmental protection under the guidance of the theory of sustainable development, thus proposing the concept of ecological highway. Ecological highway is a combination of ecology and highway construction. Its development should follow the natural ecological laws and the development requirements of regional highways. Ecological highway lighting should of course also meet the requirements of ecological environment protection and energy saving and low carbon construction.
1. Project background
1.1 Project Overview
The project is located in the southern part of a resource-based city in northern China. The area was originally a coal mining subsidence area. It is a submerged sunken wetland with a total area of ​​2,000 hectares. It used to be a messy and harsh environment. After years of comprehensive management, it has now The city's central ecological park with unique northern garden landscape features will be built. The project name is the ecological park surrounding the lake ecological landscape highway. The project runs through the surrounding water bodies of the lake area and becomes an important basic project for the development of wetland ecotourism in the city.
The project includes the main line around the lake and the various branch lines and connecting lines, with a total length of 33.7km and a total investment of 230 million yuan. In order to protect the integrity of the wetland ecosystem, the builders have shown extraordinary environmental concerns for the project. The project has adopted the goal of environmental protection and energy conservation by adopting advanced design and construction and ecological environmental protection technologies, realizing road construction and ecological environment protection and gardening. The effective coordination of the landscape not only achieves the construction orientation of “the road has a road, the road is the scenery, the integrationâ€, but also meets the strict requirements of engineering cost, construction period, quality and safety. The successful construction of the project is greatly supplemented. It enriches the design concept of ecological highways and becomes a model of environmental friendliness, resource conservation, and coordination of people, roads and environment. The project proposal was awarded the “2009 Third Prize of Excellent Engineering Consulting Achievements of Hebei Provinceâ€, and the construction drawing design won the “2009 Hebei Province Excellent Engineering Survey and Design First Prizeâ€.
1.2 Ecological Highway Lighting Requirements
As we all know, the ecological highway is based on the mutual coordination of traffic development and environment. Based on the natural virtuous cycle of ecosystems, we comprehensively consider the whole process of decision-making, design, construction, operation and management, and integrate the environment within a certain area. A road system established with economic and social development. In order to create a good visual environment for visitors and ensure traffic safety, the project has set up functional lighting.
First of all, ecological highway lighting must meet functional requirements. All kinds of lighting equipment and energy-saving measures must meet the requirements of safe, reliable, scientific and reasonable, economical use and convenient maintenance. In actual work, it should be designed according to the scale and economic strength of the project in strict accordance with the standard design and construction according to the plan. It is necessary to ensure that the lighting system functions to achieve various technical indicators and energy-saving effects, and to prevent the pursuit of energy-saving at the expense of lighting effects.
Secondly, ecological highway lighting should pursue ecological energy conservation goals. At present, building a conservation-oriented society and a low-carbon economy has become an important national policy of China. The “Eleventh Five-Year Plan for Urban Green Lighting Project†issued by the Ministry of Construction requires an annual energy saving target of 5% for road lighting. In 2010, the total power saving should reach 25%, so power saving has become an important indicator of road lighting.
