Protection measures
Environmental protection measures during the construction period
(1) materials such as fly ash, lime, cement and so on must be compacted during transportation, and the filling height should not exceed the protection rail of the hopper, so as to avoid spilling and causing the secondary dust pollution;
(2) water should be sprinkled regularly in the lots passing through the sensitive points during the highway construction, and the stacking of powdered construction materials should be covered with canopies in order to reduce the Dust;
(3) asphalt mixing materials should be mixed in a centralized site, and it is appropriate to use closed mixing, the use of advanced closed asphalt boiling equipment, and the distance from the sensitive points should not be less than 300m, and should be located in the direction of the local dominant wind direction downwind;
(4) prohibit the construction of night construction and construction machinery and equipment for the construction of the necessary and effective measures to reduce or isolate the noise;
(5) Construction workers should take protective measures to prevent noise damage to the human body during construction. In the area close to the sensitive points along the route, the construction needs to be based on the specific circumstances, to reduce the impact on the normal life and production of residents;
(6) construction camps, building materials yard should be as far as possible away from the river, construction wastewater collected by the unified precipitation can be discharged, sewage should be discharged into the city sewage network;
(7) construction site to set up a centralized garbage dumping points and timely transportation, construction In the process of earth balance, timely excavation and timely backfill, and in advance to clarify the location of the disposal site and soil extraction site;
(8) bridge construction dredging and mud throwing operations, silt should be centralized treatment, is strictly prohibited to be thrown into the river;
(9) the construction period should be as far as possible to protect the trees on both sides of the highway, woodland, do not arbitrarily destroy, are not allowed to cut down the soil and water protection forests and river and canal embankment protection forests, and minimize the impact on the grass around the work area, shrubs and bushes. Damage to grass and bushes around the operation area shall be minimized.
Operation period environmental protection measures
(1) After the project is completed and operated, the influence of vehicle traffic noise on some sensitive points along the route will be larger, so sound insulation barriers should be added on the side of sensitive buildings in close proximity;
(2) In the planning and development of plots of land on both sides of the road, a reasonable layout should be carried out to avoid the influence of traffic noise on the residential areas or cultural and educational facilities and medical institutions and other environmentally sensitive points. Institutions and other environmentally sensitive points of influence;
(3) in the night should be limited to the passage of large vehicles, in order to reduce the degree and scope of the impact of noise;
(4) both sides of the road to set up green belts, especially near the sensitive points should be planted with more trees and shrubs, not only purification and absorption of automobile exhaust, and also beautify the environment and improve the landscape along the highway;
(5) to strengthen the motor vehicle Transportation management, strictly prohibit vehicles that do not meet the environmental requirements on the road;
(6) highway waste shall not be discarded in the river or fishponds or placed in villages, schools and other environmentally sensitive points, in order to avoid secondary environmental pollution caused by waste;
(7) to take precautions against the risk of water pollution: in the west of the river and other waters of the road section construction of the side ditch, reinforcement of the protective wall and the installation of hazardous materials vehicle speed limit through the warning signs; strengthen the intelligent construction of highway operation and management, so as to improve the efficiency of the use of highway transportation resources and system security, and reduce the occurrence of pollution accidents.
