直插式連接使用的卡簧插入式連接，在聲測管兩端分別焊有子接口和母接口，輕輕插入就再也拔不出來了，所以在插入前務必檢查密封圈是否夾帶在子接口上。其操作是**為簡單，密封性比套筒式強，價格比螺旋式高，是這3種里**貴的。底管：一端焊接有底堵，另一端焊接有焊接有直插式接頭的母管管件。接頭母管件外部形狀類似于套筒，內部構造類似于汽車發(fā)動機缸體，有鍵槽。 </p> <p> 中管：一端焊有接頭子管管件，形狀類似于汽車活塞，并且上邊有兩道密封圈，一道卡簧，可以與底管的母管件完美對接，輕輕按入就可卡入鍵槽。另一端焊有母管件，以便于下一只管子相連。 </p> <p> 頂管：一端焊有接頭子管管件;另一端無接頭，加配有管帽，防止雜物落入。 </p> <p> 直插式聲測管絕大多數(shù)為壁厚在2.0~3.5之間的厚壁管，可以直接焊接在樁基鋼筋籠上，也可以用多道鐵絲進行捆綁。

1超聲波檢測原理常用的基樁動測方法包括低應變反射波法、高應變動測法、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參數(shù)的變化，來分析判斷樁身混凝土質量。螺旋式聲測管現(xiàn)貨供應，云南貿(mào)軒商貿(mào)有限公司。昆明口碑好聲測管生產(chǎn)廠家13888426708</p><p
