（3）砼采用自动计量拌合站拌和，砼输送车输送,墩台身高度大于10m时采用砼输送泵泵送入模;小于10m时采用汽车吊吊送入模。灌注砼时应对称进行，防止砼偏压过大而造成模板移位.
(4）砼灌注时采用分层振捣,每层厚度约30cm，人工使用插入式振捣棒捣固，捣固时插入点要均匀，做到快插慢拔，直至砼表面呈现平坦且不再有气泡排出为止.
(5）待砼强度达到要求后拆除模板，并及时用塑料薄膜包围、养护。 三、施工质量控制
（一)把好水泥、碎石、砂等的进料关,坚决做到不合格材料不验收、不使用。 (二)混凝土的浇注应连续进行,如因故必须间断时，其间断时间应小于前层砼的初凝时间,若超过允许间断时间，须按工作缝处理.
(三）随时观察所设置的预埋螺栓、预留孔、预埋支座的位置是否移动,若发现移位应及时校正。
四、安全措施
在灌注过程中，应注意模板、支架等支撑情况,设专人检查，如有变形、移位或沉陷应立即校正.
