兰州红楼时代广场超厚筏板基础施工技术

Construction Technology of Extra-thick Raft Foundation in Lanzhou Red Mansion Times Square

兰州红楼时代广场主楼筏板基础最厚达到8.9m,而且钢筋配置密集、层数多、自重大,通过对超厚大体积混凝土、钢筋支撑架、超低位混凝土泵管布置等采取一系列措施,确保了钢筋支撑架的安全和混凝土的正常泵送,有效控制了混凝土温差,确保了筏板工程质量。

The raft foundation maximum thickness of Lanzhou Red Mansion Times Square main building reaches 8. 9 m,and the reinforcement is intensive,multi layers and heavy self-weight,since a series of scientific measures adopted on super thick mass concrete,reinforced support frame,super low concrete pump pipe layout,etc. which ensure the safety of pump steel supporting frame and the normal of concrete delivery,the concrete temperature was controlled effectively,the raft quality of the project was ensured.
