Construction camp wastewater has two kinds, one is the construction of persons living in sewage, the main pollution factors of BOD5, COD, NH3-N, fecal coliforms count; another is the site of surface rainfall runoff water, after a wastewater mainly contains a small amount of sediment, environment without adverse effects.

Construction camp wastewater is mainly affected by life on surface water environment sewage disorderly discharge of polluting effect. Especially for environmental capacity, limited impact will be relatively large.

The construction cmaps will be located within the airport site, which produces sewage to sedimentation tank for collecting and treatment, effluent can be used in construction site dust sprinkler suppression, on water environment basic ignorance of developing sound.

Construction site to produce a small amount of domestic garbage, peak of construction site construction personnel is generally 1000 people, living garbage generated by the 0.5kg/•d, then the garbage output is 500kg/d.

Construction site has set trash, and in the season of spring and summer lime spray or buying drugs disinfection, domestic waste bagging collection, by the local sanitation departments to collect send each district living garbage disposal field of harmless disposal, construction personnel and the surrounding environment to protect the health of life, can effectively control the construction personnel and the surrounding environment for municipal soldi waste induced the incidence of infectious disease.

By adopting the measures for prevention and control of pollution, construction garbage’s impact on the environment can be reduced to the minimum, the environment can be accepted.

Construction site centralized supply of drinking water by the person responsible for the management, water containers must be cleaned every day, disinfection, the use must be stamped, and must not be placed in the prone to dust, waste gas or wastewater local impact.

Strengthen the construction of staff diet and drinking water safety and health education, must wash hands before meals, prevention of disease enters by the mouth.
4.11.5 Disease control of construction site

Construction site setting select or part-time sanitation workers in construction sites, reasonable arrangement of trash, garbage box should be timely cleaning and disinfection (sprinkled the lime powder spraying disinfectant, etc.), forbidden occurrence garbage overflow phenomenon, at any corner should not be stacked rubbish.

Construction site centralized supply of drinking water by the person responsible for the management, water containers must be cleaned every day, disinfection, the use must be stamped, and must not be placed in the prone to dust, waste gas or wastewater local impact.

For the construction personnel as the main service targets small businesses and places of entertainment, are to be obtained from the local administration of industry and Commerce Department approval, for the prevention and control of infectious diseases.

The Contractor shall have a variety of emergency medicine, and strictly control the purchase channels, regularly check the inventory situation, in order to prevent counterfeit and expired drug use.

4.12 Impact analysis and measures of rural road reconstruction

Proposed Sanqingshan airport is located in Houmentang in south of Shangrao, seated at the junction of four townships of Mao Jialing, Zaotou, Zunqiao, Chating, now the roads around the airport are: the transmeridional Zaozhou highway, two township roads from north to south. Parts of villages of Zunqiao and Zaotou mainly depend on the two township roads to Shangrao, which is connected with Ye Ting Avenue in the urban area, while Shangyu highway to the urban area in Zaotou town is far away from villages around the airport, so it is not convenient for the villagers to go out. Due to the construction of Sanqingshan airport, the roads to the urban area in parts of villages in Zaotou and Zunqiao towns are blocked.

4.12.2 Measures proposed

The rural road restoration project provides the solutions for the villagers to go out, which involves such villages as: Wan Li, Shi Gu, Mao Wan, Wan Di, Zhou Shi, Luo Shiwan, Fang Cun, Da Shanpai, Peng Jiashan, Zun Gongqiao, Wu Jiatang, Xia Wutang, Shang Huangwu, Huangwu Luojia, Gao Shanqiao, Shang Wan, Zhou Wucun and Zunqiao Jizhen.

Combined with the main roads construction of the airport, reroute construction of 320 national highway, as well as the development strategy plan of Sanjiang Xinchen, consider it in the long run and combine with the future and current to connect the two township roads that are recovery reconstruction this time with the urban area to make it convenient for people to travel. The following is the analysis and comparison of two plans of the route selection.

1. The comparison of route selection plan of the planning I in the east side of Sanqing airport:

According to Sanjiang Xincheng development strategy plan, extends Ye Ting Avenue all the way to connect with Zaozhou highway, the extension of the avenue not only has solved the recovery construction of the original road, simultaneously has also connected with the urban area of Shangrao to avoid the redundant construction after the urban development, also this path runs according to the mountain and it is convenient to be constructed.

According to the field survey and the opinions of Zaotou township government and the local village commission, there are two plans for the connection of the road and Zaozhou highway: (1) The west route plan is the suggested plan by the local government and the village committee, considering that the villagers travel with less distance, it is suggested that the connection should be in the west of Zhou Shi village, however, this route style does not favor the future road expansion and improvement of the traveling capability, also does not favor the expansion of the airport; (2) The east route plan is recommended by the program, it not only has a smoother route style, but also avoids redundant construction of the long-term development, also leaves room for the expansion of the airport. Taking the time sequence of road construction into consideration, in the near future, villagers can travel by the connection of this road and 320 national highway, and then transfer to the airport road to the urban area.

2. The comparison of route selection plan of the planning II in the west side of the airport:

Route selection is studied with the combination of the 320 national highway and the main roads of airport. This road section connects Zaozhou highway with the 320 national highway, villagers can travel by by the connection of this road and 320 national highway, and then transfer to the airport road to the urban area. According to the field survey and the opinions of Zunqiao town government and the local village committee, there are 3 plans of route selection. (1) The east route plan, considering the near access to travel for the villagers, Zunqiao township governments and the local village committee take the chance of reconstructing the road, extend Jizhen road to the north, so they suggest connecting from Jizhen main road. However, the connection will without doubt introduce vehicles into Jizhen, and increase the traffic pressure and bring traffic safety hazard, and limit the development of Jizhen. (2) The middle route plan, the plan will be connected at the brickyard in Gao Shanqiao, it has a smooth route style and avoids the traffic impacts on Jizhen, leaves room for the development of Jizhen, Zunqiao, therefore, this plan is recommended in this program. (3) The west route plan, it is connected from a col farmland in the west side of Gao Shanqiao, considering that it is vertical to Zaozhou highway, and there is a subgrade of tractor road, so the plan is for reference, however, the connection is far away from Jizhen, Zunqiao according to the plan and occupies too much farmland.

Combinind with the analysis and comparison of above plans, recommend the east plan of Planning I (Zunqiao route, 3.1 km, 6 +2 * 0.5) and the midline route plan of Planning II as preferred plans (Zhou Shi route, east of Zhou Shi village committee, Zaozhou Highway - Planning 320 national highway, 2.9 km, 6 + 2 * 0.5). At the same time, the plan suggests re-routing Jizhen section in Zuan Qiao of Zaozhou highway, to deviate from Jizhen, passing from the north side of it, and relieve traffic hidden danger, improve the traffic capacity, also leaves room for the development of Jizhen.

4.12.3 The trend of road and design parameters

Therefore, the subgrades of the two re-routed township roads are determined as 7 meters wide, and specifically 6 meters wide of two-lane pavement, with 0.5-meter-wide road shoulders on both sides. The east route plan of the Planning I of Zunqiao route is the preferred plan, which is 3.1 km long. The middle route of the Planning II of Zhou Shi route is the preferred plan, which is 2.9 km long, the specific trend of the route is shown as the following figure.
