1超聲波檢測(cè)原理常用的基樁動(dòng)測(cè)方法包括低應(yīng)變反射波法、高應(yīng)變動(dòng)測(cè)法、超聲波法、動(dòng)測(cè)法等。超聲波法檢測(cè)基樁由于檢測(cè)精度高，昆明螺旋式聲測(cè)管經(jīng)銷商、不受樁長(zhǎng)、樁徑條件限制、測(cè)試無(wú)盲區(qū)等優(yōu)點(diǎn)，在混凝土基樁檢測(cè)中應(yīng)用越來(lái)越普及。其檢測(cè)原理是對(duì)計(jì)劃采用超聲波法檢測(cè)樁身質(zhì)量的基樁，施工時(shí)在樁身中埋入聲測(cè)管，檢測(cè)時(shí)發(fā)射換能器和接收換能器分別置于兩根管道中，由聲測(cè)管底部開(kāi)始，發(fā)射探頭在某一個(gè)聲測(cè)管中邊上升邊發(fā)射高頻信號(hào)，該高頻信號(hào)穿過(guò)混凝土被另一個(gè)聲測(cè)管中同步移動(dòng)的接收換能器所探測(cè)。隨著探頭沿整個(gè)樁長(zhǎng)提升，依次測(cè)取各測(cè)點(diǎn)超聲脈沖穿過(guò)兩管道之間的混凝土，通過(guò)實(shí)測(cè)超聲波在混凝土介質(zhì)中傳播的聲時(shí)，昆明螺旋式聲測(cè)管經(jīng)銷商、波幅和頻率等參數(shù)的相對(duì)變化來(lái)檢測(cè)聲測(cè)管之間混凝土的缺點(diǎn)位置及影響程度，判定樁身完整性類別。混凝土是由多種材料組成的多相非勻質(zhì)體。對(duì)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(diǎn)時(shí)，如斷裂、裂縫、夾泥和密實(shí)度差等，聲波要繞過(guò)缺點(diǎn)或在傳播速度較慢的介質(zhì)中通過(guò)，聲波將發(fā)生衰減，造成傳播時(shí)間延長(zhǎng)，昆明螺旋式聲測(cè)管經(jīng)銷商，使．聲時(shí)增大，計(jì)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(lái)分析判斷樁身混凝土質(zhì)量。聲測(cè)管價(jià)格，云南貿(mào)軒商貿(mào)有限公司。昆明螺旋式聲測(cè)管經(jīng)銷商</p><div

(3)防止聲測(cè)管鎖口中心線位移，可在打樁進(jìn)行方向的聲測(cè)管鎖口處設(shè)卡板，阻止板樁位移。 </p> <p> (4)為保證聲測(cè)管垂直用2臺(tái)經(jīng)緯儀從兩個(gè)方向控制錘擊人土。 </p> <p> (5)由于聲測(cè)管打入時(shí)傾斜，且鎖口接合部有空隙，封閉合攏比較困難。解決的辦法一是用異形板樁(此法較困難);二是采用軸線封閉法，此法較為方便。 </p><p> 管子一般隨鋼筋籠分段安裝，每段之間的接頭可采用反螺紋套筒接口或套管焊接方案， </p> <p>
