聲測(cè)管主要是由接頭和直管焊接在一起的，在進(jìn)行焊接的時(shí)候一定要注意以下幾點(diǎn)。1、焊條使用時(shí)應(yīng)保持干燥，鈦鈣型應(yīng)經(jīng)150℃干燥1小時(shí)，低氫型應(yīng)經(jīng)200-250℃干燥1小時(shí)(不能多次重復(fù)烘干，否則藥皮容易開(kāi)裂剝落)，防止焊條藥皮粘油及其它臟物，以免致使焊縫增加含碳量和影響焊件質(zhì)量。樁基聲測(cè)管焊接時(shí)，受到重復(fù)加熱析出碳化物，降低耐腐蝕性和力學(xué)性能。焊后硬化性較大，容易產(chǎn)生裂紋。若采用同類型的焊條焊接，必須進(jìn)行300℃以上的預(yù)熱和焊后700℃左右的緩冷處理。若焊件不能進(jìn)行焊后熱處理，則應(yīng)選用鉻鎳不銹鋼焊條。2、為改善聲測(cè)管耐蝕性能及焊接性而適當(dāng)增加適量穩(wěn)定性元素Ti、Nb、Mo等，焊接性較好一些，采用同類型的鉻不銹鋼焊條時(shí)，應(yīng)進(jìn)行200℃以上的預(yù)熱和焊后800℃左右的回火處理。若焊件不能進(jìn)行熱處理，則應(yīng)選用鉻鎳不銹鋼焊條。要求控制曲率半徑。比如半徑長(zhǎng)度為，那么曲率半徑必須在所要求的公差范圍之內(nèi)。由于這些管件大多數(shù)用于焊接，為了提高焊接質(zhì)量，端部都車成坡口，留一定的角度，帶一定的邊，昆明質(zhì)量聲測(cè)管廠家，這一項(xiàng)要求也比較嚴(yán)，昆明質(zhì)量聲測(cè)管廠家，邊多厚，角度為多少和偏差范圍都有規(guī)定，昆明質(zhì)量聲測(cè)管廠家，幾何尺寸上比管件多了很多項(xiàng)。樁基聲測(cè)管表面質(zhì)量和機(jī)械性能基本和管子是一樣的。為了焊接方便。云南聲測(cè)管哪個(gè)廠家好，云南貿(mào)軒商貿(mào)有限公司。昆明質(zhì)量聲測(cè)管廠家</p><div

(1)聲測(cè)管接頭或管口、管底密封不嚴(yán)，在施工過(guò)程中漏進(jìn)泥漿或水泥漿造成堵管。(2)聲測(cè)管在安裝、灌注過(guò)程中因鋼筋扭曲或碰撞使聲測(cè)管接頭錯(cuò)位、變形或管壁變形。出現(xiàn)這種情況主要原因是選用過(guò)薄壁的聲測(cè)管。(3)灰?guī)r地區(qū)，沖孔成孔不好，鋼筋籠下沉困難時(shí)使用非常規(guī)手段使聲測(cè)管變形堵塞。(4)破樁頭時(shí)由于工人的不注意掉進(jìn)小混凝土塊引起的堵管。 </p> 解決方法：聲測(cè)管變形堵管給檢測(cè)工作帶來(lái)了很大的困難，甚至無(wú)法進(jìn)行檢測(cè)。為此基樁澆灌后檢測(cè)前發(fā)現(xiàn)聲測(cè)管堵塞時(shí)，應(yīng)采取有效措施進(jìn)行通管確保超聲波檢測(cè)的順利進(jìn)行，通管一般有以下三種方法：用粗長(zhǎng)鋼筋捅通聲測(cè)管；用高壓水沖洗清管；采用鉆機(jī)配小鉆頭進(jìn)行掃孔。<p> 一般遇到這樣的問(wèn)題，基本都是因?yàn)闃痘暅y(cè)管之間的連接不緊密造成的，但是因?yàn)榇藭r(shí)樁基聲測(cè)管已隨鋼筋籠下到樁內(nèi)，要想找到是那里的接頭連接不緊密，并且修正的話，其實(shí)是很難的，而一般常見(jiàn)的解決辦法雖然也能完成，但是十分繁瑣，好的辦好就是在下管前就能進(jìn)行檢查，及早發(fā)現(xiàn)，及早解決。 </p> <p> 工人師傅因?yàn)殚L(zhǎng)期機(jī)械勞動(dòng)，在樁基聲測(cè)管連接時(shí)，容易發(fā)生操作不到位的情況，但是很多時(shí)候工人師傅是自己無(wú)法察覺(jué)到的(如果是有意識(shí)的，那就是另一個(gè)問(wèn)題了)，如果在樁基聲測(cè)管與樁基聲測(cè)管連接的過(guò)程中，在樁基聲測(cè)管內(nèi)注入清水，那些連接不牢的地方就會(huì)出現(xiàn)滲水，這時(shí)就比較容易發(fā)現(xiàn)問(wèn)題，而一但發(fā)現(xiàn)問(wèn)題，處理起來(lái)就相對(duì)而言容易的多。如果是使用的惠世達(dá)樁基聲測(cè)管，因?yàn)槭鞘褂玫挠⒅茦?biāo)準(zhǔn)螺紋，只需用扳手簡(jiǎn)單加緊就可以解決啦。簡(jiǎn)單快捷，即不會(huì)影響工程的進(jìn)度，又相當(dāng)了檢查了一遍樁基聲測(cè)管接口的質(zhì)量，一舉兩得。昆明聲測(cè)管價(jià)格，云南貿(mào)軒商貿(mào)有限公司。</p><div
