Keywords: environmental protection of highway construction
In the past ten years, Wuyishan City has accelerated the construction of transportation infrastructure, mainly highway construction, which has made great achievements. Due to the emphasis on environmental protection, the completed Gaoxing Highway, 0# Highway in the resort and the combat readiness highway from Shixiong to Yangzhuang have strengthened the greening and beautification of the highways, adding beautiful scenery and vitality to Wuyishan.
Wuyishan City has the first batch of national key nature reserves, the first batch of national key scenic spots and national tourist resorts, and is the first batch of excellent tourist cities in China. More importantly, Wuyishan successfully declared World Cultural and Natural Heritage 1999 and 65438+February, and has a world-class tourism management brand. Good ecology and unique resources are the advantages of Wuyishan's development and the biggest capital. Developing ecological economy and realizing sustainable development is the necessity of social development and the expression of human civilization and progress. The ecological environment has a "one-vote veto" in Wuyishan City. No matter how good the investment project is, as long as it pollutes the environment, it is absolutely forbidden.
1, the significance of environmental protection in Wuyishan highway construction
Environmental protection is the general name of various measures taken by human beings to solve real or potential environmental problems, coordinate the relationship between human beings and the environment, ensure the sustainable development of economy and society, and protect human survival and health. The ecological environment of Wuyi Mountain is not only the heritage of ancestors, but also the wealth of future generations. In highway construction, we only have the responsibility to protect the construction environment, and we can't and have no right to spend it at will. Environment gives people an image and benefits; The environment is attractive and productive.
1. 1 is the need of the work in Wuyishan city center.
Tourism is the pillar industry of Wuyishan City, and "international tourism and holiday city" is the overall positioning goal of Wuyishan City. Good ecology and unique tourism resources are the guarantee for the survival and development of Wuyishan. In highway construction, we should pay attention to environmental protection along the route, give priority to the possible damage to the ecological environment caused by highway construction, and take corresponding countermeasures to avoid the damage to the ecological environment and human landscape as much as possible. The expressway in Wuyishan will be built into a green corridor running through the city, making a road a beautiful landscape, inciting the city's ecological environment, tourism environment and improving the investment environment.
1.2 is the need of highway construction itself.
In the process of highway construction, a large amount of land is occupied, and vegetation is dug, cut and destroyed in a large area, which leads to changes in geological structure, soil erosion and ecological environment, landslides and mudslides, resulting in serious damage and interruption of highways. In highway construction, soil erosion can be effectively prevented by taking measures such as saving land, balancing filling and excavation, protecting water conservancy facilities and adopting various methods for slope protection and greening. Reduce highway water damage and ensure highway safety.
2. Environmental protection countermeasures in highway construction
The leaders of Wuyishan City believe that Wuyishan is a double heritage of the world and should protect the environment at all costs. No matter how much money you spend, it is better than a piece of scenery. When building the Fufen Line (from Shixiong to Yangzhuang), it cost 300,000 yuan more to save a thousand-year-old camphor tree.
In highway construction, we should put environmental protection work in an important position, make overall planning and implement it conscientiously, so as to keep pace with the environment. Where roads are built, environmental protection work will follow. Environmental protection will not be forgotten in construction, which will promote construction and cherish every grass, tree, mountain, water and human landscape. Environmental protection will not be ignored because of highway construction, or even the damage to the environment along the highway will be sacrificed, resulting in the loss of ecological resources and new environmental pollution.
The highway projects built and under construction in Wuyishan City mainly adopt the following environmental protection countermeasures.
2. 1, strengthen the protection work in subgrade construction, and prevent the excavated and blasted earthwork from falling into river farmland. Many highways in Wuyishan City are laid along river valleys. In the process of construction, a large number of earth and stone are easy to roll down the river valley and farmland, blocking the river course and destroying farmland. Therefore, in the construction, retaining walls should be built on both sides of the river and farmland villages, and blasting should be controlled to prevent earthwork from falling into valley farmland. Those that fall into the valley or farmland should be cleaned up and transported away in time to restore the original appearance of the valley farmland.
2.2, deal with waste earth and stone in highway construction. Wuyishan mountains overlap and valleys are vertical and horizontal. Roads are mostly winding along the mountain, and the amount of earth and stone excavation is large. Except for some used for filling subgrade, most of the abandoned earth and stone should be properly disposed to avoid littering on site and causing new environmental damage. The best way is to choose the valley with less farmland and less soil erosion as the spoil ground, transport the spoil to the fill ground for unified stacking, roll it with a roller to achieve a certain degree of compaction, and then plant trees, grass, green and beautify it to restore the ecological environment.
