【正文】 1 小區(qū)多層建筑給水排水工程設(shè)計(jì) 摘 要 本設(shè)計(jì)為小區(qū)多層建筑給水排水工程設(shè)計(jì)，設(shè)計(jì)的內(nèi)容主要包括：建筑給水系統(tǒng)設(shè)計(jì)，建筑排水系統(tǒng)設(shè)計(jì)，建筑雨水系統(tǒng)設(shè)計(jì)，消火栓給水系統(tǒng)設(shè)計(jì)，自動(dòng)噴淋系統(tǒng)設(shè)計(jì)。 本建筑地上 6 層加躍層，建筑總高度為 米，一層層高 米，二層層高 米，其余層高為 米。一層為商場，二層左側(cè)為辦公室，右側(cè)為住宅，三層到躍層為住宅。 小區(qū)給水水源采用市政管網(wǎng)給水，市政管網(wǎng)壓力為 ,經(jīng)管網(wǎng)水力計(jì)算，采用管網(wǎng)直接供水和水箱聯(lián)合供水方式。在完成管網(wǎng)布置后，通過計(jì)算確定室內(nèi)給水管網(wǎng)的 管徑 、管內(nèi)流速和管段水頭損失，并選擇的合適的加壓水泵、分戶水表和總水表。 排水方式選用污廢水分流制排放的方式。直接排放進(jìn)入小區(qū)污水管道，再排放入城市下水道。 確定生活排水系統(tǒng)布置形式并通過計(jì)算確定室內(nèi)排水管網(wǎng)管徑和坡度。 雨水排水方式采用普通外排水方式。 通過計(jì)算屋頂?shù)膮R水面積，確定了雨水管的管徑。 消防系統(tǒng)，住宅、辦公室采用消火栓給水滅火系統(tǒng)，商場采用自動(dòng)噴淋滅火系統(tǒng)。 關(guān)鍵詞 ： 給水系統(tǒng)；直接供水；普通外排水；自動(dòng)噴淋 2 The Water Supply and Drainage Engineering Design of Anshan Jinfu Garden Highrise Residential Building Abstract The design is water supply and drainage engineering design of Anshan City Garden highrise residential building. The content of my design includes the design of the building w ater s upply system, the building w ater drainage system, the building stormw ater system, the hydrant w ater supply system and the automatic sprinkler system. The present building on 6 floors with the thermocline, the building height of meters, a layer of meters high, two layers upon layer meters tall, the layer is meters high. A layer is a shopping mall, tw o floors and on the left for the office, the right to housing, three layer to layer for residential. District w ater supply w ater source uses the municipal w ork water supply, the pressure of the municipal pipe work is , administered by the w ork hydraulic calculation, using direct w atersupply pipe and tank joint w ater supply mode. At the pletion of the w ork layout, determined by calculation of indoor w ater supply pipe system, the diameter of the flow velocity in the tube and tube w ater head loss, and select the suitable pressurized water pumps, individual w ater meter and total w ater meter. Drainage mode selects the way of sewa ge and w aste water discharged in separation. Direct discharge into the sew age pipe, and then discharged into the city sewer. Determine the life water system layout and determined 3 through calculation of indoor drainage pipe w ork and slope. Rainwater drai nage use the way of mon external drainage. Through the calculation of the roof of the catchment area, determined the rain w ater pipe diameter. Fire control system, residential and office use the fire hydrant extinguishing w ater supply system, market ado pts the automatic sprinkler system. Key wo rds： Water supply system。Direct water supply。Common drainage。 Automatic sprinkler 4 目 錄 前 言 ................................................................1 1 總 論 ..............................................................8 設(shè)計(jì)概況 ........................................................9 原始資料 ........................................................9 設(shè)計(jì)依據(jù) ........................................................9 設(shè)計(jì)任務(wù) ........................................................9 建筑內(nèi)部給水系統(tǒng)設(shè)計(jì)任務(wù) ....................................9 建筑內(nèi)部排水系統(tǒng)設(shè)計(jì)任務(wù) ...................................10 建筑內(nèi)部消防系統(tǒng)設(shè)計(jì)任務(wù) ...................................10 2 室內(nèi)給水系統(tǒng)設(shè)計(jì) ...................................................10 給水水源 .......................................................11 給水系統(tǒng)選擇 ...................................................11 給水系統(tǒng)的組成 .................................................11 管道布置與敷設(shè) .................................................11 水表 ...........................................................12 水表的設(shè)置條件 ..............................................12 常用水表的類型、特征 .......................................12 管段保護(hù)措施 ...................................................12 室內(nèi)給水系統(tǒng)計(jì)算 ...............................................13 計(jì)算目的 ...................................................13 計(jì)算方法與步驟 .............................................13 計(jì)算公式 ...................................................14 5 用水量計(jì)算 .....................................................16 最不利管段計(jì)算 .................................................18 建筑內(nèi)給水系統(tǒng)所需壓力 ........................................30 其他給水管道水力計(jì)算 ...........................................31 3 室內(nèi)排水設(shè)計(jì) .......................................................47 排水系統(tǒng)選擇 ...................................................47 排水系統(tǒng)組成 ...................................................47 管道、管材的布置和鋪設(shè) .........................................47 最小管徑、當(dāng)量和坡度 ...........................................48 最小管徑 ...................................................48 排水管徑坡度 ...............................................48 衛(wèi)生器具排 水當(dāng)量 ............................................49 通氣管的安裝應(yīng)注意 .............................................49 計(jì)算公式 .......................................................49 排水管 WL3水力計(jì)算過程 ........................................50 其他排水管網(wǎng)水力計(jì)算 ...........................................54 雨水排水系統(tǒng) ...................................................64 排水方式的選擇 .............................................64 雨水量計(jì)算公式 .............................................64 設(shè)計(jì)暴雨強(qiáng)度和匯水面積 .....................................64 普通外排水系統(tǒng)計(jì)算 .........................................65 4 建筑消防給水系統(tǒng)計(jì)算 ...............................................68 消火栓系統(tǒng) .....................................................68 自動(dòng)噴淋系統(tǒng) ...................................................68 6 消火栓給水系統(tǒng)計(jì)算 .............................................69 計(jì)算公式 ...................................................69 消火栓的布置 ...............................................72 水槍噴嘴處水壓 .............................................73 水帶水頭損失 .....................................
