mm～500 mm，同一根樁的聲測(cè)管外露高度宜相同。5．2 密封聲測(cè)管的底部應(yīng)采用焊接盲蓋或鋼板來(lái)保證密封不漏漿；聲測(cè)管安裝完畢后應(yīng)將上口加蓋或加塞封閉，以免澆灌混凝土?xí)r落人異物，致使孔道堵塞。5．3 固定聲測(cè)管可直接用點(diǎn)焊或鐵絲綁扎的方法固定在鋼筋籠內(nèi)側(cè)上，固定點(diǎn)的間距一般不超過(guò)2 m，其中聲測(cè)管底端和接頭部位宜設(shè)固定點(diǎn)。對(duì)于無(wú)鋼筋籠的部位，聲測(cè)管可用鋼筋支架固定。為了保證聲測(cè)管的相互平行，可以在聲測(cè)管間點(diǎn)焊三角形鋼筋架支撐。聲測(cè)管價(jià)格，云南貿(mào)軒商貿(mào)有限公司。</p><div style="width:100%;text-align:

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)管廠家直銷(xiāo)，云南貿(mào)軒商貿(mào)有限公司。昆明聲測(cè)管詢(xún)價(jià)13888426708</p><p
