Water Supply And Drainage Engineering Design for A Certain Office Building of ShanghaiGeneral Illustrate of the DesignI. Source of the designThe target of the design is water supply and drainage engineering of a certain office building of Shanghai. The task is entrusted by the “Tunnel Project Tunnel Administration Center of East Fu Xing Road”, appointed to design by the “Tunnel Project Track Traffic Design Research Institute of Shanghai”.II. Design standardThe water supply and drainage engineering design is processed according to the design specification, “Code for Design of Building Water Supply and Drainage” (GB50015-2003) strictly, while the fire-fighting system design is according to the “Code for Design of Water Extinguishing System Of Civil Buildings” (DGJ08-94-2001).III. Design principle 1. Design considerations and range of the designingAccording to the design trust deed and written instructions or comments of the related departments given by the owner, the design of the water supply and drainage system and fire-fighting system in the room is carried out according to current design specification and relevant regulations. 2. Water supply and drainage systemBecause the pressure of the municipal water supply pipe network is insufficient throughout the year, the life water supply system is the pond - the water supply system of the water pump originally. The pond and the water pump concentrate on locating the basement. 15T roof water tank is used in fire control only, storing indoor fire control water consumption of 10min. The water is supplied by the life water pump. The life water pump is started automatically.In this project, it is adopted dirty to abolish moisture discharged to shed in principle. 3. Fire-fighting systemThe indoor fire hydrant system adopts the temporary high-pressure system. The water consumption of fire control is 20L/s. Two fire pumps which are set up in the pump house for fire control (standby for each other) suck the feed pipe of municipal fire control directly. Two sets combining device of water pumps are set up. 4. Equipment and pipe fittings (1) Capital equipment and fittings meet the capital equipment and material form. (2) Pipe material and valvea. Feed pipes adopt PP-R pipes, hot to melt and join; the drainage pipes adopt UPVC pipes;b. Penstock, outlet pipes, blowdown pipes of the water tank and pond, and the pipes since water tank and pond to valves also adopt PP-R pipes all. The pond inboard wall sticks to the ceramic tile;c. The fire control pipeline adopts cast iron pipe, the flange is joined;d. Valves on the water pipe, DN50, adopt the stop valve of the Model J11T-10, while DN50, adopt the floodgate valve of the Model Z45T-10. 5. The pipeline and rig up(1) Pipeline level prop hanger should set up live according to need, concrete method pay respects to national standard S161. All pipelines should try best to be installed stick to the floor , roof beam, the post.(2) See national standard 99S304 in domestic hygiene rig up.(3) The slope of the indoor drainage pipeline:De50i = 0.035De75i = 0.025De110i = 0.020(4) Drainage pipeline should adopt 45 three direct links or four direct links and 90oblique three direct links or oblique four direct links.(5) All cleaners and polishes are taken by oneself or related trap .(6) The pipeline passes through the floor, roofing place , its space part adopts the detailed stone concrete of C10 two times to smash really, the bottom should adopt the cement mortar of M10. The width of bricks laying are not smaller than 30mm, and the height of water blocking ring is not smaller than 25mm. Sleeve pipe root inlay in ground making level layer in conformity with nest.(7) Give drainage pipeline wear roof beam , floor ,etc., it should reserve holes in a utensil, unit in charge of construction must cooperate with the building construction closely in front of the concrete in casting, check the localization and size of reserving holes.(8) Indoor fire hydrant case have wall office to put the others inlay wall install , each fire hydrant case is to see 2001 Shanghai S313 to install.(9) The adapter type of the water pump, for the SQ type on the ground fire control water pump adapter (taking the relief valve). 6. Pipeline equipment painting and warm keeping(1) PaintingRoom metal equipments that reveal prop up hanger , are needed to be brushed two layers of red lead after eliminating, and two layers of antirust paint.(2) Warm keepingThe water supply pipeline that will be exposed installation in the room adopts the ultra thin glass wool to keep warm , the thickness of heat preservation is 30mm. Outside make glass cloth to be waterproof, the concrete method can be looked up from national standard 87S159. 7. Pressure in pipelines test(1) After the supply water pipeline is installed in the room, it should be tested by 1.5 times of working pressure. The fire-fighting pipeline pressure test is processed by 1.6MPa.(2) The drainage pipeline of the ground is put or buried secretly in the room , must be poured water to test before being concealed. It should highly not be lower than the height of ground floor to pour water. Pouring water for 15 minutes after the surface of water drops, fill with and last 5 minutes , it is qualified not to drop to the liquid .(3) Drain off water and set up and is in charge of needing to make open ball of open water to test.Originally prove that has not been stated, deal with the additional remarks on the drawing according to the pertinent regulations of state.This design drawing is except that elevation is counted with the rice, the others are counted with mm. , level ground elevation is the relative elevation inside and outside the room, regard inland level ground elevation of room of ground floor as basic elevation . The feed pipe refers to in charge of the centre elevationing , the drain pipe refers to the bottom elevation while managing.IV. Architectural design materials 1. Construction design material(1) The plane figure of every storey of the building, elevation, the big master drawing of the bathroom.(2) This offi
