Designing of water supply and wastewater disposal
Our design organization has completed the design and installation of the water supply and wastewater disposal section of the water supply and drainage (sewage) complex of the training center in Moscow.
Details under the cut.
DESIGN OF WATER SUPPLY AND DRAINAGE
GENERAL INSTRUCTIONS OF DESIGN
1. This album of the working documentation of the brand ”VK” was developed in accordance with the requirements of ecological sanitary and hygienic, fire safety standards in force in the territory of the Russian Federation.
The safety of the attendants and the safety of technical means are ensured while observing the measures provided for by the project and the rules for the operation of sanitary equipment.
2. When laying plumbing communications, it is prohibited to violate the integrity of the walls and the ventorob.
3. All devices are connected according to the passport, instructions or documentation of the factory - manufacturer.
1. WATER DESIGN
1.1 The water supply source of the building is the city water supply. Water supply is carried out
in the basement. To account for the total water consumption, a water meter unit is provided with a meter DN 40 mm.
1.2 In the project, the system of cold and hot water supply is adopted as a dead end.
Pipes are placed under the ceiling and are installed from water-gas pipes GOST 3262-75D. Liners to sanitary appliances and technological equipment are made of plastic pipes using flexible connections.
Installation and acceptance of sanitary-technical devices to produce In accordance with the UN SP 3.05.01-85;
SP41 - 109–2005; SP40-102-2000.
1.3 All pipelines are isolated from Moisture condensation using “Energoflex” insulation
Insulation thickness for B1 system pipes with a diameter of up to 25mm - 6mm; diameter over 25mm-9mm.
The thickness of the insulation of trunk pipelines with a diameter of 50 mm -13 mm.
For TK system pipes with a diameter of up to 25mm, insulation thickness is 13 mm.
1.4 For the Possibility of emptying systems, trunk pipelines and distributing sections should be laid with a slope of at least 0.002.
1.5 The system is emptied through devices located in the basement.
1.6 Have All shut-off valves provide a detachable connection for replacement.
1.7 Hot Water is taken with forced circulation and is prepared in the IHP.
2. DRAINAGE PROJECT
2.1 Installation of the sewage system to produce In accordance with the requirements of SNiP 3.05.01-85; SP40-107-2003.
2.2 The sewage system in the building and the outlet is mounted from cast iron pipes SML company "DUKER. Outlets to the devices. Are mounted from plastic pipes manufactured in Russia.
2.3 When using plastic and cast iron pipes for sewage systems, follow SNiP 2.04.01-85-D
2.4 The pipes of pipes and fittings (except for double-socket couplings) must be directed against the movement of Water.
2.5 Testing Domestic sewage systems Perform by the method of water proliferation, by opening 75% of sanitary appliances connected to the tested area, During the Burden required for inspection.
2.6 Testing of sections of sewage systems that are hidden during subsequent work Perform by the Strait of Water until they are closed and draw up an inspection certificate for hidden works in accordance with the mandatory Annex 6 of SNiP 3.01.01-85
2.7 When installing branches, use only oblique tees and branch pipes.
2.8. Turns of pipelines and attachment to the riser to perform smoothly with the help of two branches of 135 degrees or oblique tee.
