</p><p style="text-indent:25px">2 聲測管對檢測的影晌常見檢測時聲測管會發(fā)生以下質(zhì)量問題：2．1 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行檢測，影響正常的施工。<span

1超聲波檢測原理常用的基樁動測方法包括低應(yīng)變反射波法、高應(yīng)變動測法、超聲波法、動測法等。超聲波法檢測基樁由于檢測精度高、不受樁長、樁徑條件限制、測試無盲區(qū)等優(yōu)點，在混凝土基樁檢測中應(yīng)用越來越普及。其檢測原理是對計劃采用超聲波法檢測樁身質(zhì)量的基樁，施工時在樁身中埋入聲測管，檢測時發(fā)射換能器和接收換能器分別置于兩根管道中，由聲測管底部開始，發(fā)射探頭在某一個聲測管中邊上升邊發(fā)射高頻信號，該高頻信號穿過混凝土被另一個聲測管中同步移動的接收換能器所探測。隨著探頭沿整個樁長提升，依次測取各測點超聲脈沖穿過兩管道之間的混凝土，通過實測超聲波在混凝土介質(zhì)中傳播的聲時、波幅和頻率等參數(shù)的相對變化來檢測聲測管之間混凝土的缺點位置及影響程度，判定樁身完整性類別?；炷潦怯啥喾N材料組成的多相非勻質(zhì)體。對于正常的混凝土，聲波在其中傳播的速度是有一定范圍的，當(dāng)傳播路徑遇到混凝土有缺點時，如斷裂、裂縫、夾泥和密實度差等，聲波要繞過缺點或在傳播速度較慢的介質(zhì)中通過，聲波將發(fā)生衰減，造成傳播時間延長，使．聲時增大，計算聲速降低，波幅減小，波形畸變，利用超聲波在混凝土中傳播的這些聲學(xué)參數(shù)的變化，來分析判斷樁身混凝土質(zhì)量。昆明正規(guī)聲測管廠家13888426708</p><p
