<br> <br> Summary: this article on multiple layers of residential construction and drainage design selection of water pipes, pipe laying, water meter out home settings, the settings of the heater and air-conditioning condensation water discharge to explore issues and made .some specific observations. <br> <br> Multistoried buildings to its facilities in the simple, low cost, easy to property management, is very popular with small and medium-sized cities real estate developers and the general public. How to press 2000, .comfortable residence Tech Engineering residential planning design guideline requirements and increase the level of residential design, as each household to create a comfortable living space, every designer's responsibility. The heart of a residential building-kitchen, bathroom, is a function of the complex, health ., safety and comfort demands high, and create complex, high technical requirements. As a result, designers must be based on overall design concepts and methods, considering the kitchen, the bathroom drainage pipes and equipment installation. Here's high-rise residential drainage design selection .of water pipes, pipe laying, water meter out home settings, the settings of the heater and air-conditioning condensation water emission issues and discussion with colleagues. <br> <br> (A) water pipes selection problems <br> <br> .Traditional water pipe materials generally use galvanized steel pipe, galvanized pipe easy rust, short life, used for transportation of water does not meet the quality standards of health, Ministry of construction, such as disadvantage is to promote the application of plastic pipes. Many cities .have been expressly prohibited the use of galvanized pipe design, promote the use of plastic pipes. Plastic pipes compared with metal pipe, with light weight, pressure intensity, conveying liquid low resistance, resistance to chemical corrosion resistance strong, easy to install, energy- .saving in steel, long life and other advantages. Plastic pipes for water supply: rigid PVC (PVC-U), high-density polyethylene (HDPE), cross-linked polyethylene (PEX), pp (PP-R, PP-C) ., polybutene (PB), aluminum-plastic composite pipe (PE-AL-PE, PEX-AL-PEX) and steel-plastic composite pipe, etc. The following table are the several kinds of water supply pipe performance comparison. Pipe performance advantages .disadvantages of long-term use of short-term use of temperature temperature of PVC pipe (PVC-U) corrosion resistance strong, hard texture, easy with UPVC monomers and additives exudate, fitting adhesive technologies require high, the curing time length ≤ 400C- .pp (EN-US) PP-R, PP-C) heat resistance good resistance to creep properties, construction is simple, only with a metal pipe connection; flow local head loss, not recycling reuse 900C950C aluminum-plastic composite pipe (PEX- .AL-PEX) good heat-resistance, heat preservation performance (EN-US) at the same pressure and temperature conditions, pipe wall thickness, using hot-melt most, need special connections tool ≤ 600C ≤ 900C aluminum-plastic composite pipe (PE .-AL-PE) easy bending, oxygen permeability, completely fire coefficient of linear expansion is small, easy tube thickness thin uneven, pipeline connection with copper pipe fittings, water current local head loss big ≤ 400C - Note: <br> <br> .1) long-term working temperature means the pipes in this temperature range service life up to 30 ~ 50 years <br> <br> 2) short-term temperature means the pipes in this temperature range service life up to 10-20 years < .br> <br> Tubing selection is the process of economic and technical comparison, technically from the pressure, temperature, use environment, installation method, etc. for consideration in conjunction with the requirements of owners and residential grades, conduct economic and technical comprehensive consideration .determined. The plastic water pipe can be used as residential living water supply pipe. Affordable housing reconciliation trapped room main face of the vast number of middle-income residents, the choice of sanitary PVC pipe (PVC-U) as water supply, to reduce .the cost of high-end commercial housing available in aluminum-plastic composite pipe (PE-AL-PE, PEX-AL-PEX) or other plastic water supply pipes as the water supply pipe. Domestic distribution point hot water temperature not exceeding 600C, .so the above pipe except PVC pipe (PVC-U) and aluminum-plastic composite pipe (PE-AL-PE), most of the pipe can be used as residential hot water pipes. <br> <br> (2) pipe laying .problem <br> <br> 1. to the drainage pipe laying General following ways. <br> <br> 1) prescribed in the kitchen, the bathroom corner. In the past residential design more this kind of laying, construction convenient, but .Ming Lu pipeline hindered House beautiful, households in the second most used when decoration light material given to hidden. <br> <br> 2) Ming installed in exterior corner office. This method applies only to a warm southern climate, the winter minimum temperature .not lower than 0 ° c to prevent the tube water freezes into ice, expansion crack pipe, households use. Pipeline laying in the exterior wall, the impact of building beautiful, is not easy for future management and maintenance. <br> <br> .3) laying in the pipe shaft. In this way make the room clean and beautiful, but pipeline logging consumes the bathroom area, and pipeline construction, maintenance is difficult. Bathroom set up centralized piping wells, pipes, the pipes are concentrated in the pipeline .well arranged, this is a comfortable residential kitchen, bathroom living embodiment of civilization. In my opinion: in upscale commercial building design should be considered when setting the toilet pipe wells, so that to improve the quality of the bathroom, but also solve the PVC .-u drainage pipe flow noise problems, improve the quality of indoor environment; for bathrooms smaller economic housing reconciliation trapped rooms, a warm areas in the South to the drainage pipe may consider laying in the exterior wall, to increase the use of bathroom space; .pipeline Ming installed indoors should be without prejudice to the kitchen, bathroom and the use of the sanitary equipment features. <br> 2. water supply branch pipe laying <br> <br> Domestic water supply pipes diameter battle de ≤ 32mm, small pipe .diameters of plastic pipes, domed State, residential water pipes to medium to adoption. Water-supply pipes Embedment way are: <br> <br> 1) Dim located in brick lane.Construction in brick walls open pipe Groove, pipe Groove width of .the outer diameter de + 20mm, depth of the outer diameter pipeline directly embed de, ducts and pipes will be fixed in pipe Groove child. <br> <br> 2) for small diameter water pipe may de ≤ 20mm located at floor-dark .(land)-screed. The construction of the floor (ground), plate surface open pipe Groove, Groove width as de + 10mm, deep 1/2de, half pipe, embedded ducts and pipes will be fixed in the ducts of the pipe. .Aluminum-plastic composite pipe and cross-linked polypropylene pipe, pipe with metal pipe connections, use Dim to be established to increase pipe Groove dimensions and flow of a large local head losses. For the kitchen and the bathroom sanitary ware layout relative concentration of residential ., can be used to connect water separator, water separator is a multiple-branch fitting, health apparatus water pipes were received from water separator. This can avoid the buried pipe fittings seepage problem. Also reduces local head loss, reducing network costs. <br .> <br> 3) drainage pipe laying <br> <br> Residential Interior horizontal drainage pipe yishe in this layer, so that the horizontal drainage pipe penetration can avoid wastewater pollutants such as entering the adjacent, pipeline maintenance also does not affect the normal .life of the neighbouring farmers. <br> <br> Kitchen sinks of horizontal drainage pipes in General in the floor surface access drainage pipe; floor drain drainage pipes shall be laid underlayer space. Now many peers are considered: kitchen floor tile, clean all .the time not to be set flush, no leakage, the kitchen is not set to leak, so that both avoid cross-drainage pipe into the adjacent, and increase the use of space in the kitchen. Toilet drainage in horizontal pipes laid in this layer .are: specific measures <br> <br> 1) improving the the bathroom floor. Ground potential high 150mm, using the back row-type toilet, washbasin, bathtub and floor drain of horizontal drainage pipe buried within the cushion. <br> < .br> 2) with sunken bath. Bathroom floor surface subsidence 350mm, health apparatus horizontal drainage pipe buried in the sinking space. <br> <br> Both of these practices and bring bathroom cross-drainage pipe laying this layer of the ground and not .into the adjacent. Buried pipeline installation, construction quality must be strict, experience your qualified before the construction of the bathroom floor, so as not to leave for future use. Bathroom floor construction can fill the ash and other lightweight materials, may also adopt the .brick construction aerial laying the ground plate, ground waterproofing treatment to be done, can reference the roof waterproofing treatment, as do two oil a fabric waterproof rubber ointment. <br> <br> (3) water meter outdoor settings problem <br> < .br> Water meter located indoors, meter reading of heavy workload, and the residential security and privacy is greatly reduced. The residence of the household water or a heat meter shows yishe outdoors. Multi-storey residential meter outdoor settings have the following form: < .br> <br> 1. the use of remote water meter <br> <br> The ordinary water meters for remote water meter, by a signal wire connection to water <br> <br> Tables and data acquisition machine, and then to .intelligent management (PC). Its advantage is that a lot of manpower to meter, accurate data, the disadvantage is the high cost. <br> <br> 2. the use of magnetic meter <br> <br> Users advance purchase water .company e-card, then put it into the memory of water meters, water is the amount on the card is automatically deducted, this way users need prepaid water, water meter higher prices. <br> <br> 3. using ordinary water meter .is located in the outdoor <br> <br> 1) meter, located in the staircase rest platform niches. Household water supply pipes after the water meter measurement into the kitchen and bathroom. This method implements the meter out room settings, project equivalent low ., but water standpipe and a meter is in effect at the stairs. It applies to the South are warm areas, kitchen, bathroom layout location close to the stairs of the House. <br> <br> 2) meter set located in the water .(water meter box). Down to-water supply, on the ground floor are located the meter (water meter box), each household water supply pipes in pipeline well laid, South area is also available on the building exterior corner office along the route .; follow to-water supply, you can set the roof water meter (water meter box). In this way increase water supply branch pipe laying length, pipe laying along exterior walls of buildings and beautiful effect. Water meter out home layout choices, be .combined with the kitchen, the bathroom floor features and developer of the specific requirements of the above several feasibility plan for economic and technical comparison. <br> <br> Residential property management perfect upscale housing in the community may be remote water meter, it is .a future application development direction for meter; property management not perfect residential district of high-end commercial House, use a magnetic meter (in the water company of this business area can design) or centrally set meter (case); in the southern region of .modular homes available ordinary water meter is located in the stairs of rest platform to reduce cost. <br> (4) the set of household water heater <br> <br> Residential design time should be reserved for the installation of water supply facilities in .conditions, or set the hot water supply facilities. So there is no centralized hot water supply of houses, consideration should be given to the installation location for household water heaters and hot and cold water piping layout. Home water heater are gas, electricity, solar .energy, etc. Gas water heater and water heater general installation in the kitchen or bathroom, building drainage design time should be reserved for a water heater installation location and hot and cold water pipe interface to make it easy for users to install their own decoration. .Solar water heater is easy to use, without the need for fuel and power, low operating cost, long life, no pollution, is very popular with our users, in the last few years many residential area in the design and construction is fully installed on .solar water heater. <br> <br> Solar water heater general installation on the roof, so that you need in the bathroom and roof water heater between hot and cold water pipes, residential design, if it does not consider the installation of solar water .heaters, household installations can only be hot and cold pipes laid along the walls, this increases the difficulty of installing households, increasing pipeline investment, and architectural beautyView. Therefore, in the water system design requires that you first consult the developer comments, whether uniform .design, construction of solar water heaters; or just reserve a solar water heater and hot and cold water piping installation location. Solar water heaters and hot water pipes can be laid in pipeline well; no pipeline well, you can bathe in the toilet near the .corner of a root of UPVC pipes de110 as solar water heaters and hot water pipe casing, in each household hygiene spacing a ground 1m Department de110 × 75 tees, as hot and cold water inlet. <br> <br> (5) air- .conditioning condensation water emissions <br> <br> In recent years, the air conditioning gradually into the millions, air-conditioning condensation water fugitive emission pollution in the external walls of buildings, is a beautiful living area. Water system design should consider air- .conditioning condensation water discharge of organized. Specific practices can reserve air conditioning outside the machine location side condensation water drain, drainage pipe selection PVC-U drain de40, the height of each layer air conditioners for easy drainage three reserved air conditioners and drainage hose direct access .. <br> <br>.
