Immigrant population in subsidence area

Textbook P 122

1) Selection requirements for construction land (site): ① Save land, occupy less cultivated land and reduce land compensation fees. In the construction of the project, try to choose the site in wasteland, poor land, mountain and open space, so as not to occupy or occupy less cultivated land and strive to save land. At the same time, we should also pay attention to saving land compensation fees and reducing the project cost.

(2) Reduce the number of resettlement. The site selection and route selection of project construction should focus on less demolition and relocation, and try not to approach or cross densely populated towns or residential areas, so as to reduce or avoid the demolition and resettlement costs and reduce the project cost. If resettlement is needed, a detailed resettlement plan for land-expropriated immigrants should be formulated, and the number of immigrants, resettlement methods, compensation standards, resettlement workload and required funds should be fully considered as the investment cost of the project.

(3) It should be selected in areas with good engineering geological and hydrogeological conditions as far as possible, and the earth resistance pressure should meet the requirements of the proposed plant area. It is strictly forbidden to select on faults, lava, quicksand layers and useful mineral deposits, as well as flooded areas, mine subsidence areas and landslide areas. The groundwater level of the construction site (site) should be as low as possible below the datum level of underground buildings.

(4) Conducive to the rational layout and safe operation of the factory. The land area and shape of the factory can meet the needs of factories and various structures, and it is suitable for arranging factories and structures according to scientific technological processes to meet the requirements of safe production. The terrain of the plant area should be flat and slightly inclined (generally 5% ~ 10%), so as to reduce the earthwork volume of leveled land, save investment and facilitate ground drainage.

⑤ Be as close as possible to places with good traffic conditions and good water and electricity supply. The construction site (site) should be close to railways, highways and waterways to shorten the transportation distance and reduce the construction investment and future operating expenses; The construction site (site) should be located in a place where cooperation conditions such as power supply and heating are easy to obtain, which is conducive to the satisfaction of construction conditions and the normal operation during the project operation. ⑥ Minimize environmental pollution.
