Code for Design of Roads in Factories and Mines is formulated to make the road design in factories and mines implement the relevant national policies and meet the requirements of safety, reliability, durability, advanced technology, economy, rationality, environmental protection and energy saving.
Design regulations in Code for Design of Roads in Factories and Mines:
4.2. 1 The width of subgrade and pavement of off-site roads shall be as specified in Table 4.2. 1.
Note: 1) Pavement width refers to roadway width;
2) The values in the table are determined according to the overall dimensions of the designed vehicle in Table 3.3. 1- 1; The width of subgrade and pavement of off-site roads for large vehicles with a vehicle width exceeding 2.65 m can be calculated and determined with reference to Articles 4.2.4 and 4.2.5.
3) In the road section with more pedestrians and non-motor vehicles, the roadbed and pavement can be widened appropriately, and the slow lane can be set;
4) The pavement width of the off-site road near the enterprise gate should be compatible with the pavement width of the off-site road with the same diameter;
5) For the secondary roads outside the factory in plain and hilly areas where the traffic volume is close to the lower limit, the pavement width can be 7m and the subgrade width can be10m; ;
6) For off-site roads with an annual average daily two-way traffic flow of slightly more than 200 vehicles, when the long-term traffic flow is not developing greatly, four-level off-site road technical indicators can be adopted, but the pavement width should be 6m and the subgrade width should be 7m;
7) Class IV off-site roads, the subgrade width can be 4.5m in sections with arduous projects or small traffic flow;
8) For auxiliary roads with less traffic and arduous projects, the pavement width can be 3m; The width of the auxiliary road leading to the explosive magazine should be 3.5m, and the width of the subgrade should be 5m.
9) For roads outside the factory in cold, frozen and snowy areas, especially sections with large longitudinal slopes, the width of subgrade can be appropriately widened according to specific conditions.
4.2.2 The paving width of roads in the factory area shall be adopted according to the numerical range listed in Table 4.2.2.
Note: 1) Enterprises are divided as follows:
A class of enterprises-large joint ventures, steel mills, ports, etc. ;
Second-class enterprises-heavy machinery (including metallurgical mining machinery, power generation equipment, heavy machine tools, etc. ), non-ferrous smelting, oil refining, chemical industry, rubber, shipbuilding, rolling stock, automobile and tractor factories, etc. ;
The third category of enterprises-light industry, textile, instrumentation, electronics, thermal power generation, building materials, food, general machinery, post and telecommunications equipment, medicine, refractories, forest products (industry), mineral processing, commercial warehouses, open pit mine maintenance sites and mine wellhead sites.
2) The values in the table are determined according to the overall dimensions of the designed vehicle in Table 3.3. 1- 1; The width of subgrade and pavement of off-site roads for large vehicles with a vehicle width exceeding 2.65 m can be calculated and determined with reference to Articles 4.2.4 and 4.2.5.
3) The division of large, medium and small factories and mines shall be implemented according to the existing relevant regulations;
4) When the mixed traffic interference is large, the upper limit should be adopted; When the mixed traffic interference is small or sidewalks are set along the main roads, the lower limit should be adopted.
4.2.3 The width of the shoulder in the factory should be 1.0m or1.5m. Depending on the site conditions, the width of the shoulder can be 0.5m or 0.75m.. ..
