1、摘要江蘇省白水蕩原屬排澇泵站裝機(jī)容量小，排澇能力低，遠(yuǎn)不能滿足整個(gè)排區(qū)的需要。本泵站的興建能確保該地區(qū)的排澇灌溉要求，有力地促進(jìn)該地區(qū)工農(nóng)業(yè)生產(chǎn)及經(jīng)濟(jì)發(fā)展。本泵站采用2臺(tái)套900ZLB-85型軸流泵，泵站設(shè)計(jì)排澇流量為4.6m3/s，正向進(jìn)水，正向出水，具有抽排功能。本設(shè)計(jì)可概括為四個(gè)部分，第一部分：機(jī)組選型；第二部分：整體布置；第三部分：穩(wěn)定計(jì)算；第四部分：結(jié)構(gòu)計(jì)算。泵站系由站身段、上游連接段及下游連接段等三部分組成。站身段包括底板、閘墩、泵房、進(jìn)水池、工作橋等；上游連接段包括前池、上游翼墻及上游護(hù)坡等三部分組成；下游連接段包括出水池、下游翼墻及下游護(hù)坡等三部分組成。本泵站的泵型為立式
2、軸流泵，泵房形式采用墩墻式濕室型泵房，泵站場(chǎng)地土類別為Ⅲ類，不能滿足穩(wěn)定要求和地基力要求，本泵站采用鉆孔灌注樁來解決此問題。在工程上部結(jié)構(gòu)施工中和投入使用后應(yīng)進(jìn)行地基沉降觀測(cè)。關(guān)鍵詞：泵站立式軸流泵設(shè)計(jì)流量排澇墩墻式濕室型AbstractBaishuidangDrainagePumpingStationProcincehadinstalledsmallcapacityofpumpunitsinjurongofJiangsu,thedrainagecapacityofthepumpingstationwasfarfrombeingabletomeetthedrainageneedsofth
