style="text-indent:25px">聲測管材質(zhì)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(dá)水和聲測管管壁的界面，再通過管壁到達(dá)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(dá)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(shù)可按下式計算：式中：——某界面的聲能透過系數(shù)；——界面兩側(cè)介質(zhì)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(shù)為聲阻抗率較低，用做聲測管具有較大的透聲率，通常可用于較小的灌注樁，在大型灌注樁中使用時應(yīng)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(shù)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(chǎn)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(nèi)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(cè)壓力，則越薄越省。昆明專業(yè)聲測管生產(chǎn)廠家云南聲測管廠家直銷，云南貿(mào)軒商貿(mào)有限公司。</p><div

src="http://tyunfile.71360.com/UpLoadFile/ynmaoxuan/2020/1/637140040587274356/6371400405872743566519434.jpg"></div><p style="text-indent:25px">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。2．3 聲測管連接處套管過長由于鋼套管過長，焊接質(zhì)量較好，密封在內(nèi)部的空氣不能排出，聲波信號要繞行很長距離或穿過空氣層才能被接收到，造成聲波信號的嚴(yán)重異常，影響樁身完整性的判定。2．4 聲測管管徑過大一般假設(shè)換能器位于聲測管的中心位置，如果聲測管的直徑較大，換能器在管內(nèi)擺動范圍較大，使耦合水層延遲增大，對聲波傳播的時問影響也更大，對檢測結(jié)果的影響就較大。</p><p 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焊或鐵絲綁扎的方法固定在鋼筋籠內(nèi)側(cè)上，固定點的間距一般不超過2 m，其中聲測管底端和接頭部位宜設(shè)固定點。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，可以在聲測管間點焊三角形鋼筋架支撐。液壓聲測管源頭好貨，云南貿(mào)軒商貿(mào)有限公司。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

聲測管的其他用途聲測管除了用作檢測通道及取代一部分鋼筋截面外，還可作為樁底壓漿的管道。試驗證明，經(jīng)樁底漿處理的灌注樁，可大幅度提高其承載力。同時聲測管還可作為事故樁缺陷沖洗與壓漿處理的管道，這時需采取措施把需壓漿的缺陷部位的管道打穿。超聲波透射法檢測，對聲測管總體的要求是：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。當(dāng)聲測管材料或安裝工藝較差時，可能造成漏漿、堵管、斷裂、彎曲、下沉、變形等事故的發(fā)生，對超聲波透射法進(jìn)行樁基完整性檢測產(chǎn)生較大影響，甚至于無法進(jìn)行超聲波透射法檢測。

聲測管的運輸方式一般都是采用汽運方式，考慮多種因素的問題選擇汽運配貨(配貨)和整車汽運(包車)兩種方式。下面聲測管廠家就來說說運輸方式的選擇。 </p> <p> 整車運輸聲測管的情況： </p> <p> 1、工地特別偏或是離工廠特別近，沒法進(jìn)行配貨，這種情況下不得不包車。 </p> <p> 2、體積達(dá)到或接近車輛能夠容納的體積(一般為鉗壓式聲測管)，這樣車輛同樣不能夠配其他貨物，繼承配貨造成運輸本錢更高或是超載。 </p> <p> 3、噸位達(dá)到或接近車輛載重量(一般是螺旋式聲測管)。假如再裝別得貨就超載，這種情況下只能包車采用整車運輸?；蛘呤侵荒軌蚺涮貏e少的貨，這種情況下司機多地卸貨本錢太高，也必需包車。 </p> <p> 4、工地特別著急使用，要求運輸時間短，必需包車才能夠按要求運抵工地。 </p> <p> 反之，則采用配貨運輸聲測管。主要知足以下前提，配貨比較利便，聲測管裝完之后車輛的噸位和體積遠(yuǎn)低于載重，工地施工聲測管不是很著急。昆明正規(guī)聲測管廠家直銷13888426708</p><p
