Chapter One. Installation instructions for the water supply and drainage pipe

One, this chapter applies to indoor and outdoor life with water supply, drainage, rainwater pipeline installation, a total of 289 Buddhism.

Second, the limits:

1. The feed water pipe:

1. inner and outer limit: the input assembly is limited to the valve, the valve without valve by an exterior wall of the building of 1.5 m;

2. and the municipal pipe line by a good water meter, without water meter, to meet the municipal pipeline is limited.

2. Tubes:

1. Interior and exterior to leave home the first Wells drainage inspection is limited.

2. the outdoor pipeline and the municipal pipe line to meet with the municipal pipeline is limited.

Three, installation of outdoor piping regardless of soil and burying, all use the same quota.

Four, this chapter includes the following content:

1. installation of pipe fittings and parts.
2. hydraulic test of water supply pipe and washing disinfection, irrigation experiment of drainage pipe.
3. water supply pipe and indoor drainage and rain water (except for the indoor cast iron feeding tube and DN 200 or higher pipes) have been included tube clamp (seat), hook, line hanging bracket Ann and deoxidation of paint.
4. indoor and outdoor water supply carbon steel pipe, cast iron pipe and rain water pipe including interior drain cleaning brush paint, paint or coating is calculated separately according to the requirements of design. The cast iron pipe for outdoor drainage that includes deoxidation, anticorrosive paint for paint with brush and asphalt, the calculation should not be repeated.

Five, the stormwater sewer fee includes in the production of steel pipe, installation, should not be repeated. Another bucket of rainwater is included in the rainwater pipe installation.

Chapter two, multiple indoor water supply aluminum plastic tube, plastic tube, etc., if the wall of the design rule or the dark (ground) floor surface is applied, artificial norm multiplied by the coefficient of 0, 80, while in actual fit pipe fittings and buckle pipe clamp, the dose of scaffolding materials.

Chapter three, the quota does not include the following contents:

1. The pipe installation does not include the flange, the installation of the valve, according to this project will be calculated accordingly.
2. The exterior water supply pipe, the indoor water supply cast iron pipe and the DN 200 pipe or without pipe support, is produced according to the first chapter that the pipe support project is calculated.
3. Heat insulation of pipe heat preservation and external thermal insulation protective layer, according to the eleventh of the corresponding calculation program.
4. The wall of the pipe (floor) establishes the steel casing, the pipe through the basement wall, the outer wall and the wall of the tank with a waterproof casing, calculated in the sixth volume of the corresponding project.
5. cast iron water supply pipe (including the feed water of the cast iron pipe culvert) according to the anti-corrosive coating of asphalt, whether the actual field corrosion protection or strengthening antisepsis, calculated by Separated according to the design requirements.
6. placement of interior and exterior pipes, foundation of pipes, earthworks, well (soil) and the surface of the dark wall apply layer of cement mortar of pipe Find the article, etc. it must be calculated separately according to the construction consumption quota of the corresponding project.
