预应力混凝土空心板梁防止气囊上浮的措施

Measures to prevention the flotation of air bag in prestressed hollow plate beam construction

结合具体工程实例,分析了目前预应力混凝土空心板梁施工中造成气囊上浮的原因,提出了切实可行的解决办法,以解决空心板梁气囊上浮造成的板顶混凝土厚度偏小的问题,从而保证预应力混凝土空心板梁的质量。

Combined with practical work the reasons caused the flotation of the air bag in construction process of prestressed hollow plate beam are analyzed, at the same time corresponding resolving measures are proposed in order to resolve the questions of insufficient thickness caused by flotation of air bag to ensure engineering quality of prestressed hollow plate beam.
