【正文】 I 中 文 摘 要 同昌水閘、泵站重建工程位于珠海市香洲區(qū) 南屏鎮(zhèn)同昌村,石豆涌(也稱掛錠角排洪渠)下游, 珠海大道南側(cè), 南屏鎮(zhèn)西側(cè)約 10km 處,水閘、泵站出口與 廣昌涌連通 ,原有水閘已不能滿足排澇需求,因此重建 。 泵站設(shè)計流量為 ,設(shè)計揚(yáng)程 ,最大揚(yáng)程 , ,選用 3 臺潛水軸流泵( 800QZ- 135),單臺泵工況為: 葉片安裝角為 +4176。, Q=, H= , n=590r/min,效率 η =%, 配套軸功率 , 電機(jī)容量 132KW, 總裝機(jī)容量 KW。 水泵 采用混凝土 制 井筒 懸吊式安裝 ,主要建筑物包括泵房、隔墩、進(jìn)水池、出水池、后墻,主廠房,副廠房等 ,設(shè)計 內(nèi)容包括水泵的選型,主要建筑物設(shè)計,穩(wěn)定計算,結(jié)構(gòu)計算等 。 水閘設(shè) 2 孔,每孔凈寬 3m,總凈寬 6m, 開敞式閘室,鋼筋混凝土結(jié)構(gòu),閘室順?biāo)鞣较蜷L 5m,垂直水流方向?qū)?, 本次設(shè)計包括水閘尺寸的計算、消力池的計算、防滲的計算、穩(wěn)定計算、結(jié)構(gòu)計算以及配筋計算。 該 水閘、 泵站的興建,將對抗旱灌溉及防洪排澇發(fā)揮重要作用。 關(guān)鍵詞: 水閘 泵站 堤防 穩(wěn)定計算 結(jié)構(gòu)計算 II Preliminary design of Tongchang gate station Song Wensheng College of Water conservancy and Civil engineering, South China Agricultural University, Guangzhou 510642, China ABSTRACT: Tongchang sluices and pumping station reconstruction project is located in zhuhai xiangzhou district has injected with chang village nanping town, Stone bean chung hang (also called spindle Angle having canal) downstream, Zhuhai avenue south, Nanping town west side about 10 km, Connect to GuangChang chung sluices, pumping station exit, Original sluices can not meet the demand of draining, so rebuilding. The pump station design flow of / s, design head , the maximum head . Use 800QZ- 135Vertical axial flow pump,a single pump working condition is: the blade installation angle of + 4 176。, Q=, H= , n=590r/min, The efficiency of η = %, supporting shaft power KW, the motor capacity of 132 KW, the total installed capacity of KW. Pump by concrete shaft suspension type installation, main buildings include pump room, lie between block, into the pool, the pool and back wall. Main workshop, deputy factory building, etc., design contents include the selection of pump, the main structure design, stability calculation, structure calculation, etc. Lock set 2 holes, each hole width of 3 m, the total width of 6 m, open type chamber, reinforced concrete structure, the lock chamber at the flow direction of 5 m long, m wide, vertical flow direction, the design includes size calculation, the calculation of stilling basin of the gate, the calculation of seepage control, stability calculation, structure calculation and reinforcement calculation Key Words: waterlocks pumping station embankment stability analysis stress analysis.
