Construction Project Overview: The project is generally laid from north to south, starting from Fengle River on the northeast side of Qianrenqiao Town, Shucheng County. It connects with the Hefei section of Huainan-Tongcheng Expressway under construction and ends at G0321 Deshang Expressway near Longtou Village, Daguan Town. The total length of the route is about 43.907 kilometers, including 33.193 kilometers in Lu'an and 10.714 kilometers in Anqing. The whole line of the project adopts the standard construction of expressway, with two-way four lanes, design speed of 120 km/H, roadbed width of 27 meters, and asphalt concrete pavement; There are 3 super-large bridges, 24 large bridges, 14 medium bridges, 4 interchanges of Qianren Bridge, Shucha, Xiaoguan and Daguan (hub), 2 overpasses, 4 ramp toll stations, 1 service area, 1 maintenance area, 1 traffic police barracks and other necessary traffic engineering and supporting facilities. During the construction period, temporary works such as 7 construction production and living areas, 3 borrow areas, 3 spoil grounds, 8 temporary soil storage yards and 37.533 km construction access roads will be set up.
Main environmental impacts and countermeasures to prevent or mitigate adverse environmental impacts:
1. Atmospheric environment. The main impacts during the construction period are construction dust, vehicle mechanical exhaust, cutting and welding smoke, asphalt smoke, etc. The main prevention and control measures are as follows: according to the requirements of "six hundred percent", take measures such as enclosure, covering, sprinkling and vehicle washing; select construction vehicles and machinery that meet the environmental protection standards; adopt closed dust removal facilities for concrete mixing station devices; The asphalt heating waste gas and mixing unloading waste gas of the asphalt mixing station are combined and directly combusted in the drying drum, and then discharged together with the collected vibration screening particles of the dryer and the natural gas combustion waste gas of the burner after reaching the standard through the secondary activated carbon adsorption treatment of the cyclone dust collector and the bag dust collector; the asphalt paving operation is standardized, and the asphalt smoke is collected and treated. During the
operation period, the maintenance and management of road surface and traffic facilities will be strengthened, the oil fume purification devices will be installed in the ancillary facilities along the line, and the oil and gas recovery devices will be built in the gas stations.
2. Water environment. During the construction period, the main impacts are the discharge of construction production wastewater and domestic sewage, and the disturbance of water body caused by bridge construction. The main prevention and control measures are as follows: the waste water in the construction site is reused after oil separation and sedimentation, and the excess waste water is used for vehicle washing, dust suppression and sprinkling; the domestic sewage in the construction camp is used for greening and road cleaning after being treated by the buried integrated biochemical treatment facility to meet the standard, and is treated by the pipe with the pipe receiving conditions; the pile foundation slurry water of the pier is treated by the slurry sedimentation tank and reused for sprinkling and dust suppression; The drilling slag shall be cleared and backfilled in time. It is strictly prohibited to pile up on the beach and abandon the water body. It is prohibited to discharge the production wastewater directly. The impact on the surface water environment during the
operation period mainly comes from the sewage discharge from toll stations and maintenance work areas. The main prevention and control measures are as follows: the sewage from Shucha interchange toll station is connected to Shucheng Zhengyuan Sewage Treatment Plant after pretreatment, the sewage from Shucha open service area is connected to Shucha Town Domestic Sewage Treatment Plant after pretreatment, and the sewage from Qianrenqiao interchange toll station is connected to Qianrenqiao Town Sewage Treatment Plant after pretreatment. The sewage from Xiaoguan Interchange Toll Station is used for greening and road cleaning after being treated by regulating pool and buried sewage treatment station.
3. Acoustic environment. During the construction period, the acoustic environmental impact is mainly the noise radiated by construction machinery and transport vehicles. The main prevention and control measures are as follows: reasonably arrange the construction site, give priority to the selection of low-noise processes and equipment, do a good job in equipment vibration prevention and noise reduction, and reduce the noise source intensity; strengthen the transportation management, reasonably arrange the construction time, and prohibit construction at night in principle near the acoustic environmental protection target; set up temporary sound barriers and enclosures for noise reduction in some sections, and strengthen the noise monitoring and construction management during the construction period. The noise during the
operation period mainly comes from vehicle traffic. It is predicted that the medium-term operation will have a greater impact on 117 acoustic environmental protection targets along the line. The main prevention and control measures are as follows: after considering the terrain and the characteristics of the protected targets, the installation of sound barriers shall be given priority. If the sound barriers cannot be installed due to the terrain and other reasons, sound insulation windows shall be installed. Sound barriers shall be set for 116 acoustic environmental protection targets, totaling 39320 linear meters, and sound insulation windows shall be installed for 1 acoustic environmental protection target (5 households). Carry out tracking and monitoring during the operation period, and improve noise prevention and control measures according to the monitoring results.
4. Ecological environment: The main impacts are the change of land use pattern, the destruction of vegetation, the disturbance of wildlife, soil erosion, biomass loss and other impacts. The main protection measures are as follows: optimize the site layout, strictly control the construction land occupation; reasonably arrange the construction plan, avoid special protection periods such as breeding, overwintering, migration and migration of important species, adopt low-noise and low-vibration construction technology, and adopt cofferdam construction for wading bridges to reduce the impact; implement the requirements of water and soil conservation, separate stripping and stockpiling of surface soil, and timely carry out ecological restoration.
5. Soil, groundwater environment and solid waste management. Solid wastes mainly include construction spoil, pile foundation drilling slag and mud, construction waste, domestic waste, waste engine oil, etc. The main prevention and control measures are as follows: spoil, drilling residue and mud shall be transported to the waste disposal area, construction waste shall be recycled first, and those that cannot be recycled shall be transported to the compliance disposal area. It is strictly prohibited to dump at will, discard along the ditch and fill the river channel. Domestic waste shall be collected and treated by the local environmental sanitation department. Waste engine oil and sludge shall be stored temporarily and regularly handed over to qualified units for treatment and disposal. During the construction and operation period, key anti-seepage measures shall be taken in the temporary storage of hazardous wastes, sewage treatment areas, mechanical equipment maintenance and other places to avoid the pollution of groundwater and soil environment in the region.
6. Risk prevention: The risk scenarios are mainly the leakage of mechanical oil products from vehicles during the construction period, the leakage of dangerous goods from traffic vehicles during the operation period, resulting in water pollution, and the leakage, fire or explosion of gas stations in the service area. The main preventive measure are: preparing contingency plan for environmental emergencies, conducting regular drills, ensuring emergency response capabilities, and taking emergency measures in time after an accident occurs; setting up emergency supplies such as oil absorption felts and oil containment booms on the construction site; Runoff collection system and accident emergency pool shall be set on the bridge deck across Fengle River, Hangbu River and Shulu Trunk Canal, and warning signs, monitoring system and emergency telephone shall be set on sensitive sections, so as to reserve sufficient environmental emergency materials; gas stations shall be constructed and operated in a standardized manner. Opinions of
relevant departments: the approval of the development and reform department on the feasibility study of the project and the approval of the transportation department on the preliminary design of the project.
