聲測(cè)管連接處套管過長(zhǎng)由于鋼套管過長(zhǎng)，焊接質(zhì)量較好，密封在內(nèi)部的空氣不能排出，聲波信號(hào)要繞行很長(zhǎng)距離或穿過空氣層才能被接收到，造成聲波信號(hào)的嚴(yán)重異常，影響樁身完整性的判定。2．4 聲測(cè)管管徑過大一般假設(shè)換能器位于聲測(cè)管的中心位置，如果聲測(cè)管的直徑較大，換能器在管內(nèi)擺動(dòng)范圍較大，使耦合水層延遲增大，昆明聲測(cè)管詢價(jià)13888426708，對(duì)聲波傳播的時(shí)問影響也更大，對(duì)檢測(cè)結(jié)果的影響就較大。昆明聲測(cè)管廠家，云南貿(mào)軒商貿(mào)有限公司。昆明聲測(cè)管詢價(jià)13888426708</p><div

<p>

</p><p> 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、不受樁長(zhǎng)、樁徑條件限制、測(cè)試無盲區(qū)等優(yōu)點(diǎn)，在混凝土基樁檢測(cè)中應(yīng)用越來越普及。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)超聲脈沖穿過兩管道之間的混凝土，通過實(shí)測(cè)超聲波在混凝土介質(zhì)中傳播的聲時(shí)、波幅和頻率等參數(shù)的相對(duì)變化來檢測(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，聲波要繞過缺點(diǎn)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(shí)間延長(zhǎng)，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，來分析判斷樁身混凝土質(zhì)量。昆明聲測(cè)管規(guī)格，云南貿(mào)軒商貿(mào)有限公司。</p><div

聲測(cè)管的材質(zhì)要求要求有足夠的機(jī)械強(qiáng)度，保證在灌注混凝土過程中不會(huì)變形且與混凝土粘結(jié)良好，不致在聲測(cè)管和混凝土間產(chǎn)生縫隙包裹不佳，影響測(cè)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(cè)管的優(yōu)點(diǎn)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(cè)管。 </p> <p> 3．3 裝卸和貯存要求聲測(cè)管聲測(cè)管在裝卸搬運(yùn)過程中，應(yīng)采用機(jī)械或人工將聲測(cè)管抬起運(yùn)送至制定地點(diǎn)，嚴(yán)禁拋擲和滾動(dòng)，以防聲測(cè)管變形彎曲。吊裝時(shí)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(cè)管。聲測(cè)管在工地存放時(shí)，宜放入倉(cāng)庫(kù)或料棚內(nèi)，以防雨淋生銹。室外堆放時(shí)，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(shí)間不宜超過一個(gè)月。批發(fā)聲測(cè)管廠家，云南貿(mào)軒商貿(mào)有限公司。昆明聲測(cè)管詢價(jià)13888426708</p><p
