解決方法：聲測管變形堵管給檢測工作帶來了很大的困難，甚至無法進(jìn)行檢測。為此基樁澆灌后檢測前發(fā)現(xiàn)聲測管堵塞時，應(yīng)采取有效措施進(jìn)行通管確保超聲波檢測的順利進(jìn)行，通管一般有以下三種方法：用粗長鋼筋捅通聲測管；用高壓水沖洗清管；采用鉆機(jī)配小鉆頭進(jìn)行掃孔。當(dāng)堵塞嚴(yán)重?zé)o法通管時，必須遵循以下處理原則：當(dāng)為某橋的頭一根樁時，必須進(jìn)行鉆芯檢測；當(dāng)為某橋的非***根樁時，施工單位申報(bào)變更檢測方法，使用低應(yīng)變反射波法或高應(yīng)變動測法，并經(jīng)監(jiān)理、業(yè)主代表和質(zhì)監(jiān)負(fù)責(zé)人簽名后，予以實(shí)施；若某橋多次出現(xiàn)堵管問題，須適時進(jìn)行鉆芯檢測。 </p><p style="text-indent:25px">3.聲測管的材料質(zhì)量控制聲測管的材料質(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 聲測管的外觀要求聲測管應(yīng)順直，彎曲度不大于5 mm/m；聲測管兩端截面應(yīng)與其軸線垂直，并應(yīng)無毛刺；不允許有裂縫、結(jié)疤、折疊、分層、搭焊缺陷存在；管內(nèi)應(yīng)暢通無異物。3．2 聲測管的材質(zhì)要求要求有足夠的機(jī)械強(qiáng)度，保證在灌注混凝土過程中不會變形且與混凝土粘結(jié)良好，不致在聲測管和混凝土間產(chǎn)生縫隙包裹不佳，影響測試結(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管。液壓聲測管源頭好貨，云南貿(mào)軒商貿(mào)有限公司。</p><div

style="text-indent:25px">安裝質(zhì)量控制：超聲波法檢測對聲測管總體要求是：接頭牢靠不脫開，密封不漏漿；管壁平整不打折，平順無變形；管體豎直不歪斜；管內(nèi)暢通無異物。5．1 埋設(shè)聲測管埋設(shè)深度應(yīng)埋設(shè)至灌注樁的底部，其上端應(yīng)高于灌注樁頂面300 mm～500 mm，同一根樁的聲測管外露高度宜相同。5．2 密封聲測管的底部應(yīng)采用焊接盲蓋或鋼板來保證密封不漏漿；聲測管安裝完畢后應(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2 m，其中聲測管底端和接頭部位宜設(shè)固定點(diǎn)。對于無鋼筋籠的部位，聲測管可用鋼筋支架固定。為了保證聲測管的相互平行，可以在聲測管間點(diǎn)焊三角形鋼筋架支撐。昆明聲測管哪個廠家好，云南貿(mào)軒商貿(mào)有限公司。昆明正規(guī)聲測管廠家批發(fā)</p><p

樁底聲測管彎曲因施工不當(dāng)，造成樁底聲測管向內(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 樁身聲測管傾斜或彎曲變形聲測管綁扎不牢或綁扎間距過大，在澆筑混凝土過程中，聲測管受混凝土擠壓發(fā)生傾斜或彎曲變形，管間距離變大或變小，直接影響檢測結(jié)果的分析判定，甚至無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，影響正常的施工。<span style="display:none;"></span>昆明正規(guī)聲測管廠家批發(fā)</p><p
