解決方法：聲測管變形堵管給檢測工作帶來了很大的困難，甚至無法進行檢測。為此基樁澆灌后檢測前發(fā)現(xiàn)聲測管堵塞時，應采取有效措施進行通管確保超聲波檢測的順利進行，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；采用鉆機配小鉆頭進行掃孔。當堵塞嚴重無法通管時，必須遵循以下處理原則：當為某橋的頭一根樁時，必須進行鉆芯檢測；當為某橋的非***根樁時，施工單位申報變更檢測方法，使用低應變反射波法或高應變動測法，并經監(jiān)理、業(yè)主代表和質監(jiān)負責人簽名后，予以實施；若某橋多次出現(xiàn)堵管問題，須適時進行鉆芯檢測。昆明聲測管廠家供應液壓聲測管，云南貿軒商貿有限公司。</p><div

style="text-indent:25px">聲測管材質的選擇，以透聲率較大、便于安裝及費用較低為原則。聲脈沖從發(fā)射換能器發(fā)出，通過耦合水到達水和聲測管管壁的界面，再通過管壁到達聲測管管壁與混凝土的界面，穿過混凝土后又需穿過另一聲測管的兩個界面而到達接收換能器。因此，聲測管形成4個界面，每個界面的聲能透過系數可按下式計算：式中：——某界面的聲能透過系數；——界面兩側介質的聲阻抗率發(fā)射和接收換能器之間4個界面的總透聲系數為聲阻抗率較低，用做聲測管具有較大的透聲率，通?？捎糜谳^小的灌注樁，在大型灌注樁中使用時應慎重，因為大直徑樁需灌注大量混凝土，水泥的水化熱不易發(fā)散：鑒于塑料的熱膨脹系數與混凝土的相差懸殊，混凝土凝固后塑料管因溫度下降而產生徑向和縱向收縮，有可能使之與混凝土局部脫開而造成空氣或水的夾縫，在聲通路上又增加了更多反射強烈的界面，容易造成誤判。聲測管的直徑，通常比徑向換能器的直徑大l0mm即可，常用規(guī)格是內徑50-60mm。管子的壁厚對透聲率的影響很小，所以，原則上對管壁厚度不作限制，但從節(jié)省用鋼量的角度而言，管壁只要能承受新澆混凝土的側壓力，則越薄越省。</p><p style="text-indent:25px">超聲波檢測：（三）樁外孔透射法當樁的上部結構已施工或樁內沒有換能器通道時，可在樁外緊貼樁邊的土層中鉆一孔作為檢測通道，檢測時在樁頂面放置一發(fā)射功率較大的平面換能器，接收換能器從樁外孔中自上而下慢慢放下，超聲波沿樁身混凝土向下傳播，并穿過樁與孔之間的土層，通過孔中耦合水進入接收換能器，逐點測出透射超聲波的聲學參數，根據信號的變化情況大致判定樁身質量。由于超聲波在土中衰減很快，這種方法的可測樁長十分有限，且只能判斷夾層、斷樁、縮頸等。液壓聲測管現(xiàn)貨供應，云南貿軒商貿有限公司。</p><div

1、在樁基下鋼筋籠的時候很關鍵，聲測管在跟鋼筋籠綁到一起拾一定要結實，聲測管安裝好后用管帽或者木塞封死，以防止雜物的進入。 </p> <p> 2、鋼筋籠放入樁孔時應防止扭曲，管子應保持一致，聲測管與鋼筋籠分開安裝。 </p> <p> 3、聲測管的上端，應高于灌注樁頂面300mm~500mm，同一根樁的聲測管的高度相同。 </p> <p> 4、焊接鋼筋時，應該避免焊流液蹦到聲測管的管子上，螺旋式聲測管絲扣損壞是致命傷。 </p> <p> 5、聲測管檢測時注入清水，如果是污水，會導致結果不穩(wěn)定。昆明聲測管源頭好貨，云南貿軒商貿有限公司。昆明螺旋式聲測管批發(fā)13888426708</p><p style="text-indent:25px">螺旋式聲測管廠家直銷，云南貿軒商貿有限公司。昆明聲測管廠家供應</p><p
