The common basic knowledge of building electrical engineering and building water supply and drainage: (1) The task of building water supply system is to economically and reasonably transport water from the outdoor water supply pipe network to various water distribution faucets, production water equipment or fire-fighting equipment installed indoors, so as to meet the user's rapid elimination of water quality and quantity.

The common basic knowledge of building electrical engineering and building water supply and drainage resistance: (1) The task of building water supply system is to economically and reasonably transport water from the hail lead of the outdoor water supply pipe network to various distribution faucets, production water equipment or stall spring fire fighting equipment installed indoors, so as to meet the user's rapid elimination of water quality and quantity.

2..The system consists of a water supply project that includes an outdoor water source inlet, a water supply and return riser, a water supply horizontal branch pipe, a water appliance, a valve, a casing, a fire ring, a water meter, a support, an earthwork and filling, etc.

Answer]: cThe knowledge points assessed in this question are the classification of building drainage systems. According to the nature of waste and sewage accepted by the system, the building drainage system can be divided into the following categories.

1) Domestic drainage system: exclude waste and sewage from residential buildings, public buildings and factories.

2) Industrial waste and sewage drainage system: eliminate waste and sewage generated in the production process.

3) Roof rainwater drainage system: collect and remove rainwater and ice and snow melt water from the roof cover.

The above systems can be set up separately, and waste and sewage with similar properties can be discharged together. In general, the roof rainwater system should be set separately.

The general components of the internal drainage system of the building are: sanitary appliances, drainage pipe system, ventilation pipe system and cleaning equipment.

1. Sanitary appliances: Sanitary appliances, also known as sanitary ware, sanitary equipment, are containers or devices that supply water and accept and discharge sewage or dirt. Sanitary appliances are the starting point of the internal drainage system of the building, and are used to meet various sanitary requirements in daily life and production process, and to collect and remove sewage and wastewater;

2. Drainage pipeline system: composed of appliance drainage pipe, drainage horizontal branch pipe, drainage riser and discharge pipe, etc.;

1) Appliance drain pipe: Appliance drain pipe refers to the short pipe connecting sanitary ware and drainage cross branch pipe. Except for toilets, water seals should be installed on the drains of other appliances;

2) Drainage horizontal branch pipe: The function is to transfer the sewage sent by the drainage pipe of the appliance to the riser. There should be a certain slope, slope to the riser;

3) Drainage riser: used to collect the sewage discharged from each horizontal branch pipe connected to it, and then discharge it to the discharge pipe;

4) Discharge pipe: It is used to collect the sewage discharged from one or several risers and discharge it into the outdoor drainage pipe network. The discharge pipe is the connecting pipe section between the indoor drainage riser and the outdoor drainage inspection well, and its pipe diameter shall not be less than the maximum riser pipe diameter to which it is connected.

3. Snorkel system: The function of the snorkel is to discharge the harmful gases generated in the pipeline into the atmosphere, so as not to affect the indoor environmental hygiene, reduce the corrosion of waste water and waste gas to the pipeline, and supply air to the pipe when draining, reduce the change of air pressure in the riser, prevent the water seal of the sanitary ware from being damaged, and ensure the smooth flow of water;

4. Cleaning equipment: In order to dredge the drainage pipeline, in the indoor drainage system, it is generally necessary to set up cleaning equipment, inspection ports, inspection wells and other cleaning equipment.

Legal basis

Article 4 of the Design Standards for Building Water Supply and Drainage.

The layout of indoor drainage pipes should comply with the regulations of hail excavation

1) The distance from the sanitary appliances to the outdoor inspection well should be the shortest, and the pipeline should have the least turn;

2) The drainage riser should be close to the drainage point with the largest drainage volume or the worst water quality;

3) Drainage pipes shall not be laid in food and valuable commodity warehouses, ventilation rooms, electrical machine rooms and elevator machine rooms;

4) Drainage pipes shall not pass through deformation joints, flues and air ducts; When the drainage pipe must pass through the deformation joint, corresponding technical measures should be taken;

5) Drainage buried pipelines shall not be arranged in places that may be crushed by heavy objects or pass through the foundation of production equipment;

6) Drainage pipes and ventilation pipes shall not pass through the living room, dining room, and source core drainage riser should not be close to the interior wall adjacent to the bedroom;

7) The drainage pipe should not pass through the window, wall cabinet, and shall not pass through the storage room;

8) Drainage pipes should not be arranged in places that are susceptible to mechanical impact. When it cannot be avoided, protective measures should be taken;

9) Plastic drains should not be arranged near heat sources. When it cannot be avoided and causes the heating temperature of the pipe surface to be greater than 60 degrees, thermal insulation measures should be taken;

10) When the outer surface of the drainage pipe may condense, anti-condensation measures should be taken according to the nature of the building and the requirements of use.
