筏板钢筋混凝土基础顶面上预埋钢板,厚且重,面积占整个基础面积的90%,整体平整度要达到3mm。施工中采用特殊措施与工艺,克服混凝土浇筑时对钢筋笼、预埋钢板冲击形成的上浮力,解决预埋钢板整体大面积浮置在钢筋笼顶面上随时调整标高、精确定位、无飘移的难题,确保大面积整体预埋钢板下面的混凝土振捣充分、无空洞形成。
Raft reinforced concrete foundation embedded in the top surface of the steel, thick and heavy, the area accounted for 90% of the entire foundation area, the overall flatness to reach 3mm. During the construction, special measures and techniques are adopted to overcome the buoyancy caused by the impact on the steel cage and the embedded steel plate when the concrete is poured, so as to solve the problem that the overall large area of the embedded steel plate is floated on the top surface of the steel cage to adjust the elevation at any time, Difficulties, to ensure that a large area of the whole concrete embedded under the steel plate full vibration, no holes formed.
