Chapter one. Water supply and drainage pipeline installation instructions
One, this chapter apply to indoor and outside simulation subsequently water supply, drainage, rainwater pipe installation, a sum of 289 Buddhism.
Second, the boundaries:
1. The feed water pipe:
(1) inside and external boundary: the approach set is bounded to the valve, the valve without valve by a building outside wall 1.5 m;
(2) and municipal pipe descent by a water meter well, no water meter well, to meet following municipal pipeline is bounded.
2. Pipes:
(1) indoor and external to leave home the first drainage inspection Wells is bounded.
(2) the external pipeline and municipal pipe origin to meet in imitation of municipal pipeline is bounded.
Three, external pipe installation irrespective of the pitch and bury, every use the similar quota.
Four, this chapter includes the considering content:
1, pipe fittings and parts installation.
2, water supply pipe hydraulic exam and disinfection washing, drainage pipe irrigation experiment.
3, indoor water supply and drainage and rainwater pipe (except for the indoor cast iron feed pipe and DN 200 pipes or higher) have been included pipe clamp (seat), hook, descent hanging bracket to Ann and paint derusting.
4, indoor and uncovered water supply carbon steel pipe, cast iron pipe and the rainwater pipe including indoor drainage cleaning brush paint, the paint or coating is calculated separately according to the design requirements. external drainage cast iron pipe including derusting, brush paint anticorrosion primer and asphalt, shall not be repeated calculation.
Five, steel rain storm sewer quota includes in the steel pipe production, installation, must not be repeated. new rain water bucket is included in the rainwater pipe installation.

Chapter two, indoor water supply aluminous model combination tube, plastic tube, etc., if the design rule wall or floor (ground) surface dark apply, norm exaggerated multiplied by the coefficient of 0.80, while in genuine adjusting pipe fittings and pipe clamp, buckle, the dosage of scaffold materials.

Chapter three, the quota does not enlarge the gone contents:
1. The pipe installation does not count up the flange, valve installation, according to this project shall be calculated accordingly.
2. The uncovered water supply pipe, indoor water supply cast iron pipe and DN 200 pipes or not including pipe support, occurs according to the first chapter the pipe hold project is calculated.
3. The pipe heat preservation heat insulation and thermal insulation outer protective layer, according to the eleventh of the corresponding computation program.
4. The pipe wall (floor) set in the works the steel casing, pipeline crossing the basement wall, uncovered wall and wall of reservoir using waterproof casing, calculated at the sixth volume of corresponding project.
5, water supply cast iron pipe (including the feed water of cast iron pipe storm sewer) according to pronounce past asphalt anticorrosive coating, if the actual ring corrosion support or increase antisepsis, calculated separately according to the design requirements.
6, indoor and outdoor pipeline laying, pipeline foundation, earthwork, with ease (ground) and the wall surface dark apply pipe glue mortar layer, etc should be calculated separately according to the corresponding project construction consumption quota.
