VK Court Project

General Data

This project provides for internal water supply and sewerage of the administrative building of the Federal Arbitration Court at St. Petersburg,

st. Yakubovich, d. 6.

This project is based on the following materials:

Specification of State Unitary Enterprise "Vodokanal St. Petersburg" No. 50/09/120 707/08-0-1 from 07.04.08

- design tasks

- architectural and construction drawings of normative materials

The project has been completed in accordance with the following regulatory documents:

SNip 2.04.0185 * - "Internal water supply and sewerage of buildings"

SNiP 3.05.0185 - "Internal Sanitary and Technical Systems"

SNiP 2.08.0289 * "Public buildings and structures";

Initial data for the designed building:

Total building area - 4302.3 m2

Construction volume - 14200 m3

Storey - 7 floors

Number of office employees - 70 people

Office operation mode - 8 hours

Cafe for judges - 100 p.m.

The cafe's running time is 12 hours.

The source of cold water supply of the building is the public water supply system from ul. Yakubovich Du = 150 mm. Source of hot water supply - from heating networks.

Hot Water Supply System

Hot water is supplied to the administrative building from heating networks. Internal hot water supply networks with inducement circulation. The circulation of the network is provided separately for each riser and main line .

Air vents are installed at the upper points of the system. Drain devices are provided at the lower points.

Hot water supply networks are performed: risers and main ones made of fusiotherm plastic pipes, supply to the sun. technical equipment made of Rehau metal plastic pipes.

The lines are isolated by a Thermaflex layer with a thickness of 9 mm. The project provides for the installation of shutoff valves.

Pressure requirements for hot water supply:

N of =31.50 m, where

19.5 m - geometric height of the design instrument

5.0 m - free head at washbasin

7.00 m - total head loss in internal networks

Internal hot water supply networks shall be laid together with cold water supply pipes.

Domestic sewage system

Waste water removal from the sun. technical instruments are carried out by gravity with subsequent connection to sewage risers. Prefabricated main pipelines pass in the structure of the insulated floor of the 3rd floor (above the arch), as well as under the slab of the 1st floor.

The network is equipped with revisions, cleaners.

Pipe material: risers, lines and outlets from Duker cast iron pipes, discharge from the sun. instruments - polypropylene " Uponor."

All pipelines are attached by clamps with rubber gaskets to prevent pipe damage.

Pipelines at the intersection of floors, internal walls and partitions are laid in sleeves. The places of passage of sewage risers through the inter-storey floors are sealed with cement mortar for the entire thickness of the ceiling of at least 200 mm (before horizontal drainage) and a width of at least 300 mm. Before sealing, pipes are wrapped with roll waterproofing material without clearance.

Exhaust parts of sewage risers are removed at a distance of 0.3 m from flat non-operated roof and heat insulated with a layer of mineral wool 50mm, including a unit of passage through the roof.

Domestic wastewater discharge is carried out according to the designed output into the inspection well of the internal yard network of municipal sewerage and further into the general alloy street communal sewage Du = 300 mm on the street. Yakubovich .

Production sewage system

The production water is drained from the kitchen equipment by gravity with subsequent connection to the sewage risers. Prefabricated main pipelines from the cafe pass in the structure of the insulated floor of the 3rd floor (above the arch), as well as under the floor slab of the 1st floor.

The network is equipped with revisions, cleaners.

Pipe material: risers, lines and outlets from Duker cast iron pipes, discharge from the sun. instruments - polypropylene " Uponor."

All pipelines are attached by clamps with rubber gaskets to prevent pipe damage.

Pipelines at the intersection of floors, internal walls and partitions are laid in sleeves. The places of passage of sewage risers through the inter-storey floors are sealed with cement mortar for the entire thickness of the ceiling of at least 200 mm (before horizontal drainage) and a width of at least 300 mm .

Before sealing, pipes are wrapped with roll waterproofing material without clearance.

The exhaust part of the sewage riser of the production sewage system is removed at a distance of 0.3 m from the flat non-operated roof and is heat insulated with a layer of mineral wool 50mm, including a unit for passage through the roof.

The discharge of production water is carried out according to the designed release to the fat separator, then to the inspection well of the internal pit network of municipal sewerage and then to the general alloy street municipal sewage Du = 300 mm on the street. Yakubovich .

Fat separator EuroREK Omega NS7 (Labko). Domestic and industrial sewers have different releases.

Internal Water Drain

The discharge of rain and meltwater from the roof of the building through the system of internal drains is provided for by the projected release into the inspection well of the internal pit network of communal sewage and further into the general alloyed street communal sewage Du = 300 mm on the street. Yakubovich .

The drainage network is equipped with revisions and cleaning. Duker cast iron pipes, pressure.
