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(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?？捎糜谳^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。</p><p> 按照鐵道部“關(guān)于做好客運專線鐵路基樁檢測工作的通知”(鐵建設(shè)函[2006]464號)的技術(shù)要求，對混凝土灌注樁應(yīng)按其基樁總數(shù)的****做無損檢測。當(dāng)基樁混凝土強度達到設(shè)計強度的70%，且不小于15MPa，方可進行無損檢測。對于地質(zhì)變化異常復(fù)雜地聲測管區(qū)的混凝土灌注樁，樁身質(zhì)量應(yīng)采用聲波透射法進行檢測及驗收。

聲測管的工藝質(zhì)量控制4．1 聲測管的埋置數(shù)量聲測管的埋置數(shù)量，交通和建筑規(guī)范略有區(qū)別，交通部公路工程基樁動測技術(shù)規(guī)程規(guī)定如表1規(guī)定。4．2 聲測管的直徑超聲波檢測放入聲測管中的換能器直徑一般為30 mm左右或更小，規(guī)范規(guī)定聲測管內(nèi)徑比換能器直徑宜大10 mm～20 mm，因此選用聲測管宜選用直徑40 mm～60 mm鋼管。4．3 聲測管的壁厚聲測管的壁厚要求，除能滿足工藝性能外，還要確保安全使用，宜符合表2要求。聲測管的材料質(zhì)量控制主要從外觀質(zhì)量和材質(zhì)要求兩方面進行控制液壓聲測管現(xiàn)貨供應(yīng)，云南貿(mào)軒商貿(mào)有限公司。昆明質(zhì)量聲測管批發(fā)市場</p><p

聲測管的材質(zhì)要求要求有足夠的機械強度，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。 </p> <p> 3．3 裝卸和貯存要求聲測管聲測管在裝卸搬運過程中，應(yīng)采用機械或人工將聲測管抬起運送至制定地點，嚴禁拋擲和滾動，以防聲測管變形彎曲。吊裝時宜用纖維吊裝帶并注意輕拿輕放，不能一頭著地，以防泥土阻塞聲測管。聲測管在工地存放時，宜放入倉庫或料棚內(nèi)，以防雨淋生銹。室外堆放時，應(yīng)存放在干燥的地方，下墊枕木，上方不可壓重物，并有遮蓋物防雨防潮，存放時間不宜超過一個月。昆明質(zhì)量聲測管批發(fā)市場</p><p
