直插式連接使用的卡簧插入式連接，在聲測(cè)管兩端分別焊有子接口和母接口，輕輕插入就再也拔不出來(lái)了，所以在插入前務(wù)必檢查密封圈是否夾帶在子接口上。其操作是**為簡(jiǎn)單，密封性比套筒式強(qiáng)，價(jià)格比螺旋式高，是這3種里**貴的。底管：一端焊接有底堵，另一端焊接有焊接有直插式接頭的母管管件。接頭母管件外部形狀類(lèi)似于套筒，內(nèi)部構(gòu)造類(lèi)似于汽車(chē)發(fā)動(dòng)機(jī)缸體，有鍵槽。 </p> <p> 中管：一端焊有接頭子管管件，形狀類(lèi)似于汽車(chē)活塞，并且上邊有兩道密封圈，一道卡簧，可以與底管的母管件完美對(duì)接，輕輕按入就可卡入鍵槽。另一端焊有母管件，以便于下一只管子相連。 </p> <p> 頂管：一端焊有接頭子管管件;另一端無(wú)接頭，加配有管帽，防止雜物落入。 </p> <p>

style="text-indent:25px">3.聲測(cè)管的材料質(zhì)量控制聲測(cè)管的材料質(zhì)量控制主要從外觀質(zhì)量和材質(zhì)要求兩方面進(jìn)行控制。3．1 聲測(cè)管的外觀要求聲測(cè)管應(yīng)順直，彎曲度不大于5 mm/m；聲測(cè)管兩端截面應(yīng)與其軸線垂直，并應(yīng)無(wú)毛刺；不允許有裂縫、結(jié)疤、折疊、分層、搭焊缺陷存在；管內(nèi)應(yīng)暢通無(wú)異物。3．2 聲測(cè)管的材質(zhì)要求要求有足夠的機(jī)械強(qiáng)度，保證在灌注混凝土過(guò)程中不會(huì)變形且與混凝土粘結(jié)良好，不致在聲測(cè)管和混凝土間產(chǎn)生縫隙包裹不佳，影響測(cè)試結(jié)果。其力學(xué)性能、抗彎曲性能、耐壓扁性能、密封耐壓性能應(yīng)滿足規(guī)范要求。鋼薄壁聲測(cè)管的優(yōu)點(diǎn)是便于安裝，可直接固定在鋼筋籠內(nèi)側(cè)上，固定方式可用電焊或綁扎；鋼管剛度較大，埋置后可基本上體質(zhì)其平行度和平直度。所以一般混凝土灌注樁推薦使用鋼薄壁聲測(cè)管。云南聲測(cè)管生產(chǎn)廠家直銷(xiāo)，云南貿(mào)軒商貿(mào)有限公司。昆明正規(guī)聲測(cè)管現(xiàn)貨</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。東川區(qū)聲測(cè)管</p><p
