5．4聯(lián)接鋼筋籠放人樁孔時應(yīng)防止扭曲，聲測管一般隨鋼筋籠分段安裝。將帶有底蓋的聲測管固定在頭一節(jié)鋼筋籠上，其余的暫時固定在制作好的待下的鋼筋籠上，下鋼筋籠時將聲測管的上一節(jié)對接好后插上，同時把聲測管綁扎在鋼筋籠上，依次而做。每段之間的接頭可采用反螺紋套筒接口或套管焊接方案，反螺紋套筒接頭應(yīng)采用軟性的橡膠密封圈，套管聯(lián)接可選一段長80mm左右的鋼套筒，內(nèi)徑略大于聲測管外徑，將兩根聲測管套起來，用電焊將套筒與聲測管上下兩端焊結(jié)起來。無論哪種接頭方案都必須保證接頭有足夠的強度，保證聲測管不致受力彎曲脫開；在較高的靜水壓力下聯(lián)接部位密實不漏漿，接口內(nèi)壁應(yīng)保持平整，不應(yīng)有焊渣、毛刺等物，以免妨礙換能器的自如移動。若聲測管需截斷，宜用切割機切斷，切割后對管口進行打磨消除內(nèi)外毛刺，不宜以電焊燒斷；焊接鋼筋時，應(yīng)避免焊液流濺到管體上或接頭上。昆明質(zhì)量聲測管現(xiàn)貨云南聲測管生產(chǎn)廠家直銷，云南貿(mào)軒商貿(mào)有限公司。</p><div

</p> <p> 1、工地特別偏或是離工廠特別近，沒法進行配貨，這種情況下不得不包車。 </p> <p> 2、體積達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。 </p><p 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。螺旋式聲測管廠家直銷，云南貿(mào)軒商貿(mào)有限公司。</p><div

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。昆明質(zhì)量聲測管現(xiàn)貨</p><p
