Tech drawings for sewage and water supply systems of a car checkpoint
Design techical solutions of water supply and sewage system for checkpoint.
Design of water supply and sewage
The initial data for the development of this section of the project were:
- Terms of reference for the development of the project;
- Master plan, executed on the geo-base M1: 500;
- Technical conditions for connection to the centralized system of surface wastewater disposal;
- Architectural and construction drawings;
Works, tests and commissioning should be conducted in accordance with SP 73.13330.2012, in compliance with safety standards, as well as in accordance with instructions and passports of manufacturers of materials and equipment. Pipelines are insulated with Thermaflex pipes. Color of pipelines to accept in accordance with GOST 14202 - 69. Installation and installation of imported equipment is allowed only with the availability of a Technical Certificate (certificate of conformity) issued by certification bodies GOST R (Decree of the Government of the Russian Federation of December 12, 1997 N 1636). installation is necessary registration of acts of the performed works and drawing up executive documentation.
Internal water drains
Removal of rain and melt water from the roof of the building is carried out by the system of internal drains. For the reception of rainwater on the roof of buildings are installed drain funnels 110mm TechnoNIKOL with crimp flange. In the pavilion, funnels DN 75 of type HL62.1 / 7 (manufactured by HUTTERER & LECHNER) with a sheet catcher are installed. Release of drains provided for the blind area, then trays in the urban stormwater network. Outlets at the intersection with the outer wall should be insulated min. wool or other insulating layer, the hole from the inner and outer sides is sealed with cement mortar. On releases to provide an emphasis, the dimensions of the stops to determine the place. To ensure a positive temperature in the drain funnels and in the outlets for the blind area at negative ambient temperature, they are heated to a temperature of + 5 ° C - + 10 ° C. The installation of gutters is carried out hidden in mines, channels made of polypropylene (PP-N) sewer pipes 50-110 mm TU 4926-010-41989945-98 with a device of opening hatches for access to revisions and cleanings. The K2 system also receives conditionally clean drains - drainage from ventilation systems and conditioning. Connect to the K2 system with a jet break.
