工程根據(jù)設(shè)計(jì)要求選用OVM15系列錨具。其中張拉端錨具采用OVM15-6及OVM15-7錨具，固定端采用Pm15-1錨具。 </p> <p> 金屬波紋管的質(zhì)量要求工程采用φ75～80mm雙波金屬波紋管，是由寬36mm、厚0.3mm的鋼帶經(jīng)過(guò)輥軋及連續(xù)咬口彎邊而制成。 </p> <p> 金屬波紋管不得破損，進(jìn)場(chǎng)后應(yīng)認(rèn)真檢驗(yàn)，妥善保護(hù)，搬運(yùn)時(shí)應(yīng)輕拿輕放，不得拋甩或拖拉。 </p> <p> 總結(jié) </p> <p> 在金屬波紋管工程的使用中，必須注意金屬波紋管配套使用的鋼絞線、錨具和金屬波紋管的質(zhì)量要求，注重產(chǎn)品質(zhì)量，才能保證**終工程的質(zhì)量。 </p>造成金屬波紋管管道壓漿不密實(shí)的 <p> 金屬波紋管管道壓漿直接關(guān)系到預(yù)應(yīng)力混凝土的結(jié)構(gòu)強(qiáng)度，在預(yù)應(yīng)力橋梁施工中必須保證金屬波紋管的壓漿密實(shí)度，否則會(huì)嚴(yán)重的影響橋梁的結(jié)構(gòu)。 </p> <p> 造成金屬波紋管管道壓漿不密實(shí)的原因主要有七個(gè)： </p> <p> 在金屬波紋管管道壓漿過(guò)程中，突然停電，管道中已經(jīng)存在漿體，但未從出漿口出漿，調(diào)運(yùn)發(fā)電機(jī)，發(fā)電機(jī)安裝不及時(shí)，致使無(wú)法補(bǔ)漿，然后只能從出漿口和0號(hào)塊處預(yù)留的排氣孔進(jìn)行補(bǔ)漿。 </p> <p> 金屬波紋管在0號(hào)塊處的排氣孔(安裝不牢固或堵塞)未冒漿，但出漿口連續(xù)滿管出漿，且進(jìn)漿稠度與出漿稠度相同。 </p> <p> 錨墊板上的壓漿孔在混凝土施工中未堵塞好，進(jìn)漿后無(wú)法鑿開的，且開洞難度大無(wú)法施工。金屬波紋管管道計(jì)算壓力應(yīng)取計(jì)算溫度下對(duì)應(yīng)的操作壓力。</p><div

金屬波紋管管道的應(yīng)力計(jì)算中所采取的溫度和壓力稱為計(jì)算溫度和壓力。 </p> <p> 由于金屬波紋管管道在絕大多數(shù)時(shí)間是在正常操作狀態(tài)下運(yùn)行，所以可將計(jì)算溫度和壓力取為操作溫度和操作壓力，但應(yīng)考慮到**不利的情況。當(dāng)設(shè)計(jì)溫度和設(shè)計(jì)壓力與操作溫度和操作壓力相差不大時(shí)，也可將計(jì)算溫度和計(jì)算壓力取為設(shè)計(jì)溫度和設(shè)計(jì)壓力。 </p> <p> 根據(jù)金屬波紋管的相關(guān)標(biāo)準(zhǔn)，對(duì)金屬波紋管的溫度和壓力的計(jì)算方法有如下規(guī)定。 </p> <p> 對(duì)于無(wú)隔熱層管道，介質(zhì)溫度低于65℃時(shí)，取介質(zhì)溫度為計(jì)算溫度，介質(zhì)溫度等于或高于65℃時(shí)，取介質(zhì)溫度的95%為計(jì)算溫度。 </p> <p> 對(duì)于有外隔熱層管道，除另有計(jì)算或經(jīng)驗(yàn)數(shù)據(jù)外，應(yīng)取介質(zhì)溫度為計(jì)算溫度。金屬波紋管常見(jiàn)的失效形式有以下情況。昆明鍍鋅金屬波紋管直銷</p><p
