斷樁，即鉆孔灌注樁在混凝土灌注環(huán)節(jié)，混凝土中混入了泥漿、砂礫，這些物質將灌注混凝土隔開并形成上下兩段，導致混凝土截面積受損或變質，進而影響了成樁質量。一般來說，斷樁的成因大致有以下幾點：①由于混凝土坍落度過小，或由于石料粒徑過大、導管直徑較小，在灌注過程中導管被堵塞，無法在混凝土初凝前疏通好，不得不將導管提起，形成斷樁；②由于運輸或等待時間過長等原因使混凝土發(fā)生離析，又沒有進行二次攪拌，灌注時大量骨料卡在導管內，不得不提出導管進行清理，引起斷樁；③混凝土灌注過程中發(fā)生坍孔，無法清理，或使用吸泥機清理不徹底，使灌注中斷造成斷樁；在提拔導管時，將導管提拔過量，使導管底口拔出混凝土面，或使導管口處于泥漿層，形成斷樁。欽州大型旋挖鉆機哪家好？南寧徐工旋挖鉆機</p><p
