Pingdingshan Section of the Middle Route of South-to-North Water Transfer Project

General situation of Pingdingshan section of the middle route project of South-to-North Water Transfer Project

The main canal of the Middle Route of South-to-North Water Transfer Project enters Baoan Town, Ye County, Nanyang, passes through Ye County, Lushan County, Baofeng County, Jiaxian County 18 Township (town), crosses the He Lan River in Anliang Town, Jiaxian County, and enters Yuzhou City, Xuchang, with a total length of 1 15.53 km, including Ye County and Lushan County. There are large and small river ditches 1 13, and there are more than 200 aqueducts, culverts, inverted rainbows, bridges and other buildings. Among them, the larger crossing projects are: Lihe Aqueduct, Shahe Aqueduct and Beiru River Inverted Siphon Project. The main canal in our city covers a total area of 58,400 mu, including 24,000 mu permanently and 34,400 mu temporarily, with 4 170 people resettled and 654,380+006,900 square meters of houses demolished.

The cross section of the main canal of the South-to-North Water Diversion Project in our city is trapezoidal. The designed canal bottom is 25m wide, the water depth is 7m, and the water front slope is 1:2~ 1:3.5 and1:/0.5. The width of the upper mouth varies with the terrain, and the water surface width is generally 60m. The inner slope is protected by cast-in-place concrete, the outer slope is protected by turf, and the local slope is protected by masonry. The top of the dike is 5m wide, and the toe of the dike is provided with 5m drainage ditch and 8m shelterbelt, covering an area of about 130m.

In order to ensure the safety of water quality, according to the Notice of the State Council South-to-North Water Diversion Office, Ministry of Water Resources, State Environmental Protection Administration and Ministry of Water Resources on Delineating Water Source Protection Zones on both sides of the Main Canal of the Middle Route of South-to-North Water Diversion Project, the outer edges of non-open channel sections (including tunnels, culverts, inverted siphons, aqueducts and other water conveyance facilities) extend 50 meters to both sides, and the secondary water source protection zone is the channel section with the groundwater level lower than the bottom extending outward 150 meters. For the canal section where the groundwater level is higher than the bottom of the canal, according to the different drainage methods, the outer drainage section and the inner drainage section of the first-class water source protection area extend from the sideline of the project management scope to both sides 100 m and 200 m respectively; The cross section of the sewage outlet of the secondary water source protection area extends from the sideline of the project management scope to the left and right respectively not less than 2000m and1500m; The left and right sides of the inner row section extend not less than 3000m and 2500m.

The water supply supporting project plans to set up five outlets in our city, including four outlets in Yexian, Baofeng, Jiaxian and urban areas, and four outlets in Luohe and Zhoukou 1. The annual distribution of water supply in our city is 250 million cubic meters, including 20170,000 cubic meters in urban areas (including 70 million cubic meters in new urban areas), 26 million cubic meters in Yexian, 0/23,000 cubic meters in Baofeng/kloc and 0/00,000 cubic meters in Jiaxian/kloc. The total length of water pipes (canals) in our city's water supply supporting project is 74 kilometers, involving four counties and two districts 19 townships (towns), namely Ye County, Lushan, Baofeng, Jiaxian County, Xinhua and zhanhe. The water supply supporting project covers a total area of 3,209.38 mu, including permanent 123.58 mu, temporary 3 185.8 mu, and demolished houses of 26 13.56 square meters.

According to the budget estimate in the preliminary design stage, the total investment of the main canal and water supply supporting projects in our city is more than 654.38+0.2 billion yuan.

The middle route project of South-to-North Water Transfer Project has brought rare opportunities and challenges to the economic and social development of our city, and its far-reaching influence will gradually emerge in the construction and operation of the project. First, it is conducive to improving the total amount of urban water resources and regulation capacity, enhancing water supply security, and promoting the improvement of the ecological environment along the route. The average water allocated to our city by the Middle Route of South-to-North Water Transfer Project for many years accounts for more than 1/3 of the total urban industrial and domestic water consumption in the water receiving area in 2030. The second is to stimulate economic growth. The middle route project of South-to-North Water Transfer Project, the annual investment intensity of our city exceeds 3 billion yuan. According to the calculation of relevant departments, the construction period will boost the city's economy by at least one percentage point every year. Third, the project has formed many landscapes, which can further promote the development of tourism and cultural industries along the route in harmony with the existing landscapes. The fourth is to expand employment. According to the estimate that every investment of 50,000 ~ 6,543,800 yuan will create an employment opportunity, 30,000 ~ 60,000 employment opportunities will be added to our city every year during the construction period. Fifth, it provides great opportunities for the development of many industries in our city, such as construction, building materials, power supply, transportation, catering, tertiary industry, real estate development and so on. According to preliminary estimation, the main canal project of South-to-North Water Diversion Project in Henan Province needs about 2.5 million tons of cement, 445,000 tons of steel, and aggregate130,000 cubic meters, which can directly create a profit of about 500 million yuan for building materials enterprises, and the construction tax, building materials tax and other taxes in the province are more than 654.38 billion yuan, and our city will also occupy a very considerable share in it.
