水下混凝土的要求十分特殊,应当考虑到传统混凝土施工与水下混凝土施工的区别。由于桥梁的构造原因,与平常的道路和建筑都有差别。比如,桥梁下方因为过水的需要和施工的简便考虑可能选用较少的支撑柱并要考虑不能粗的过分。所以,这种单柱往往承受了太大的压力,并且数量少,如果发生损伤难以补救。并且破坏面较大。因此,对于单体支柱的质量要求很高,灌注技艺应当充分落到实处。 Underwater concrete requirements are very special, should take into account the difference between traditional concrete construction and underwater concrete construction. Due to the structural reasons of the bridge, there are differences from ordinary roads and buildings. For example, because of the need to pass water underneath the bridge and for ease of construction, fewer support columns may be used and should not be considered overly rough. Therefore, this single column is often subjected to too much pressure, and a small number, if the damage is difficult to remedy. And damage the larger surface. Therefore, the quality requirements of the monolithic column are high, and the perfusion technique should be fully implemented.
