style="text-indent:25px">超聲波檢測(cè)：聲測(cè)管安裝好之后，按照超聲波換能器通道在樁體中的不同的布置方式，超聲波透射法基樁檢測(cè)主要有三種方法：（一）樁內(nèi)跨孔透射法此法是一種較成熟可靠的方法，是超聲波透射法檢測(cè)樁身質(zhì)量的**主要形式，其方法是在樁內(nèi)預(yù)埋兩根或兩根以上的聲測(cè)管，在管中注滿(mǎn)清水，把發(fā)射、接收換能器分別置于兩管道中。檢測(cè)時(shí)超聲波由發(fā)射換能器出發(fā)穿透兩管間混凝土后被接收換能器接收，實(shí)際有效檢測(cè)范圍為聲波脈沖從發(fā)射換能器到接收換能器所掃過(guò)的面積。根據(jù)不同的情況，采用一種或多種測(cè)試方法，采集聲學(xué)參數(shù)，根據(jù)波形的變化，來(lái)判定樁身混凝土強(qiáng)度，判斷樁身混凝土質(zhì)量，跨孔法檢測(cè)根據(jù)兩換能器相對(duì)高程的變化，又可分為平測(cè)、斜測(cè)、交叉斜測(cè)、扇形掃描測(cè)等方式，在檢測(cè)時(shí)視實(shí)際需要靈活運(yùn)用。 </p><p> 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(lèi)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(lèi)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(chē)成坡口，留一定的角度，帶一定的邊，這一項(xiàng)要求也比較嚴(yán)，邊多厚，角度為多少和偏差范圍都有規(guī)定，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。螺旋式聲測(cè)管源頭好貨，云南貿(mào)軒商貿(mào)有限公司。</p><div
