Project name: Quanjiao to Lukou Expressway Construction site of Anhui Highway Section
: Quanjiao County, Chuzhou City Maanshan City and
County Construction Unit: Anhui Quanlu Expressway Co., Ltd.
Environmental Assessment Unit: Shanghai COSCO Shipping Environmental Technology Co., Ltd.
Construction Project Overview: The project is generally laid from north to south, starting from the northeast side of Xianghe Town, Quanjiao County, and connecting with S98 Chuzhou Branch Line. The terminal point is located near Xiaobao Village, Shiyang Town, Hexian County, and ends at the boundary of Anhui and Jiangsu provinces, connecting the Jiangsu section of Lukou-Quanjiao Expressway, with a total length of about 22.359 kilometers. The whole line of the project adopts the standard construction of two-way six-lane expressway, with a design speed of 120 km/H, a subgrade width of 34.5 meters for the integral subgrade section, and an asphalt concrete pavement; There are 2 super-large bridges, 8 large bridges, 5 medium and small bridges, 22 passages, 39 culverts, 4 interchanges, 2 separated interchanges, 2 toll stations, 1 maintenance work area, 1 management sub-center and other necessary traffic engineering and supporting facilities. During the construction period, temporary works such as 8 construction production and living areas, 6 borrow areas and 33.3 km construction access roads will be set up.
Main environmental impacts and countermeasures and measures to prevent or mitigate adverse environmental impacts:
1. Water environment. The main impacts during the construction period are the discharge of production wastewater and domestic sewage, the disturbance of water body by bridge construction, and the possible discharge of drilling slag, spoil, mud, etc. The main prevention and control measures are as follows: set up and improve wastewater collection and disposal measures in the construction site, build a rain and sewage diversion system, reuse the wastewater after oil separation and sedimentation, and use the excess wastewater for vehicle washing, dust reduction and sprinkling, etc; The construction process of steel cofferdam is adopted. The waste mud and drilling slag are collected and transported to the mud tank on the bank for temporary storage. After sedimentation treatment in the sedimentation tank, the supernatant is reused for construction. It is not allowed to precipitate and discard in the river channel. The domestic sewage in the area with pipe acceptance conditions is treated by pipe acceptance. The domestic sewage in the construction camp is used for greening and road cleaning after being treated by the box-type integrated biochemical treatment facilities. The impact on the surface water environment during the
operation period mainly comes from the discharge of domestic sewage from toll stations, maintenance work areas, management sub-centers, etc. The main prevention and control measures are: self-built integrated treatment facilities, temporary storage pool, and reuse after treatment up to standard.
2. Acoustic environment. The noise during the construction period mainly comes from the operation of construction machinery and vehicle transportation in construction activities such as excavation, drilling, piling and concrete pouring. 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 mid-term operation will have a greater impact on 29 acoustic environmental protection targets along the line. The main prevention and control measures are as follows: noise reduction measures of noise barriers are adopted in 21 places, and the total length of noise barriers is about 6070 meters; sound insulation windows are adopted in 3 places and about 16 households; Sound barrier and sound insulation window measures are taken in 5 places, of which the total length of sound barrier is about 1989 meters and the height is 4 meters. At the same time, sound insulation window measures are taken for 187 households within the evaluation scope and 1 Quanjiao County Glorious Home/Quanjiao County Relief Management Station/Quanjiao County Children's Welfare Home and Social Welfare Home/Boai Senior Apartment.
3. Atmospheric environment. The main impacts during the construction period are construction dust, asphalt fume, welding fume, vehicle mechanical exhaust, etc. The main prevention and control measures are as follows: according to the requirements of "six hundred percent", measures such as enclosure, covering, watering and vehicle washing are taken to suppress dust; the mixer in the mixing station is fully closed, dust removal and purification facilities are installed, and local smoke and dust collection devices are set in the prefabrication yard and reinforcement processing yard; the asphalt paving operation is standardized, and the asphalt smoke and dust are collected and treated; the construction vehicles and machinery that meet the environmental protection standards are selected. During the
operation period, the maintenance and management of road surface and traffic facilities shall be strengthened, and the kitchen of ancillary facilities along the line shall be equipped with lampblack purification measures.
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. Construction management should be strengthened to reduce the encroachment and destruction of surrounding vegetation. The main protection measures are as follows: strictly delimit the construction scope and define the construction red line; reasonably arrange the construction plan, avoid the special protection periods such as breeding, wintering, migration and migration of important species, and strictly prohibit the construction personnel from hunting and destroying wild animals and plants in the construction area; implement the requirements of water and soil conservation, strip and stockpile the surface soil separately, and carry out ecological restoration in time.
5. Soil, groundwater environment and solid waste management. The main types of solid waste are construction waste, engineering waste dregs, bridge construction mud, domestic waste, waste engine oil, etc. The main prevention and control measures are as follows: the domestic garbage shall be collected and disposed by the local environmental sanitation department; the waste soil, mud and construction waste shall be recycled first, and those that cannot be recycled shall be transported to the compliant spoil ground for disposal; the waste engine oil and oil sludge shall be temporarily stored according to the specifications and shall be regularly handed over to the qualified unit for 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 oil spill accidents caused by wading construction, oil spill or cargo leakage caused by vehicle overturning on the highway, etc. The main preventive measure are as follows: prepare contingency plan for environmental emergencies, carry out drills regularly, ensure emergency response capability, and take emergency measures in time after an accident occurs; prepare emergency materials such as adsorption materials and quarantine interception materials on the construction site; set up runoff collection systems and emergency pools for accidents on the bridge decks across Chuhe River, Xianghe River and Zhaodian River. Opinions of
relevant departments: the reply of the development and reform department on the feasibility study of the project, the reply of the transportation department on the preliminary design of the project, and the reply of the competent forestry department of Quanjiao County on the project crossing Nanping Mountain Provincial Forest Park.
