Water consumption for greening; 4 Water consumption for water features and recreational facilities; 5 Water consumption for roads and squares; 6 Water consumption for public utilities; 7 Unforeseen water consumption and leakage of water from pipeline network; 8 Water consumption for fire-fighting. Note: Fire fighting water consumption is only used for checking the calculation of pipe network, and is not a normal water consumption. 3.1.2 Residential water consumption of residential community, according to the population of the community and Table 3.1.9 of the maximum daily residential water consumption quota is determined by calculations. 3.1.3 Residential community water consumption of public **** building should be used according to the nature of its use, scale, using the water consumption quotas in Table 3.1.10 is determined by calculations. 3.1.4 Greening watering in residential community, according to the nature of its use, scale, using the water consumption quota in Table 3.1.10 is determined by calculations. .4 The water consumption quota for greening watering in the residential area can be calculated according to the watering area of 1.0~3.0L/m2 d. The water consumption quota for watering in the public swimming pool can be increased according to the nature of use and scale. The water consumption of communal swimming pool, water swimming pool and water feature shall be determined according to the provisions of 3.9.17, 3.9.18 and 3.11.2. 3.1.5 The water consumption quota for watering of roads and squares in residential area can be calculated according to the watering area of 2.0~3.0L/m2 d. 3.1.6 The water consumption and pressure for fire-fighting in residential area as well as the fire duration shall be determined in accordance with current "Fire Prevention Code for Building Design" and "Fire Prevention Code for High-rise Buildings". Code for Fire Protection in Building Design" and "Code for Fire Protection in Design of High-rise Civil Buildings". 3.1.7 The sum of leakage water and unforeseen water in pipe network of residential community can be calculated as 10%~15% of the maximum daily water consumption. 3.1.8 Water consumption of utilities in residential community should be provided by the management of the facility, and when there is no major utility, no additional water consumption will be counted. 3.1.9 Maximum daily water consumption for residential The daily domestic water consumption quota and the hourly variation coefficient can be determined according to Table 3.1.9, depending on the type of residence, building standard, degree of perfection of sanitary appliances and area. Table 3.1.9 Residential maximum daily domestic water consumption quota and hourly variation coefficient residential category sanitary apparatus 3.1.11 Building indoor and outdoor fire fighting water consumption, water supply extension time, water supply pressure, etc., should be in accordance with the current relevant fire fighting norms. 3.1.12 Industrial enterprise building, management personnel of the domestic water consumption quota can be taken as long as the shortcomings of the 30 ~ 50L / person class; workshop workers of the domestic water consumption quota should be determined according to the nature of the workshop, generally appropriate to adopt the workshop water consumption quota. The nature of industrial enterprise building, generally appropriate to use 30 ~ 50L / person class; water time for 8h, hourly variation coefficient of 1.5 ~ 2.5. Industrial enterprise building shower water quota, should be based on the "industrial enterprise design health standards" in the workshop of health characteristics of the grading to determine the general can be used for 40 ~ 60L / person times, the continuation of the water supply time of 1h. 3.1.13 car washing water quota, should be based on the vehicle Use, road ...... >>
Question 7: real estate construction What is the extranet The extranet refers to the pipeline, electrical, communication and other facilities within the district, outside the building.
Question 8: What information is needed for the construction of the heat external network Construction program, drawings, start report, construction technology transfer records, site temporary agreement visas, hidden project inspection records, construction inspection records, valve test reports, unit project quality acceptance report, material quality testing witness records, divisional project quality acceptance report, sub-construction project quality acceptance report, steel pipe inspection acceptance records, Industrial pipeline installation records, heating pipeline hydrostatic test records, heating pipe network project completion of the handover letter, heating pipe network project strength, tightness test records, heating pipe network project cleaning nail inspection records, heating pipe network project test run records, pipe weld welding records, pipe trench base trench bottom project inspection and acceptance records, completion report, completion acceptance certificate, construction program, the main raw materials and components factory certificate.
Question 9: Hello, I would like to ask, what is included in the power grid project, can you tell me in detail? This I do not understand very much want to understand! Street light control cabinets, semi-rigid plastic pipe buried laying, cable trench digging, rectifier power transformers, power cables, garden lights, lawn lamps, floodlights.
Power substation, box variable equipment procurement, installation, commissioning and from the park opening and closing station to the substation, box variable high-voltage cable laying and the park substation, box variable to the low-voltage distribution cabinets within the low-voltage cable laying of the single project.
Question 10: Which seniors point out the construction process of the external network? Construction process: according to the map measurement, placement, piling → digging pipe trench → trench bottom matting treatment → review elevation → pipe prefabrication, corrosion → pipe under the pipe to find the right → pipe mouth connection → part of the soil backfill → check before the pressure test → segmented system test → hidden check → backfill → the system of the final water pressure test.
