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，昆明螺旋式聲測(cè)管廠家直銷13888426708、耐壓扁性能、密封耐壓性能應(yīng)滿足規(guī)范要求，昆明螺旋式聲測(cè)管廠家直銷13888426708，昆明螺旋式聲測(cè)管廠家直銷13888426708。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。液壓聲測(cè)管哪個(gè)廠家好，云南貿(mào)軒商貿(mào)有限公司。昆明螺旋式聲測(cè)管廠家直銷13888426708</p><div

聲測(cè)管對(duì)檢測(cè)的影晌常見(jiàn)檢測(cè)時(shí)聲測(cè)管會(huì)發(fā)生以下質(zhì)量問(wèn)題：2．1 樁底聲測(cè)管彎曲因施工不當(dāng)，造成樁底聲測(cè)管向內(nèi)彎曲，間距變小，使發(fā)射與接收換能器不保持平行，超聲脈沖聲速異常偏高，波幅降低，聲速曲線不正常。由于樁底是缺陷易發(fā)生部位，根據(jù)此類曲線很難判定樁底是否存在缺陷，很可能發(fā)生漏判、誤判，給工程留下安全隱患。2．2 樁身聲測(cè)管傾斜或彎曲變形聲測(cè)管綁扎不牢或綁扎間距過(guò)大，在澆筑混凝土過(guò)程中，聲測(cè)管受混凝土擠壓發(fā)生傾斜或彎曲變形，管間距離變大或變小，直接影響檢測(cè)結(jié)果的分析判定，甚至無(wú)法給出樁身完整性類別，只能采取鉆芯或其他可靠的方法進(jìn)行檢測(cè)，影響正常的施工。<span
