设备基础预留孔洞,当混凝土浇灌2～4小时,拆除孔洞的模板时,发现在0.5米深以内的预留孔洞,只要采用压杠起模就可以了。但是,当深度超过0.5米时,尽管模板刨光、刷隔离剂,起模仍十分困难,费工费力,材料浪费也较大。拆模一不小心,还会使边缘孔的孔 The foundation of the equipment is reserved for holes. When the concrete is poured for 2 to 4 hours and the template of the hole is removed, the reserved hole within 0.5 m depth is found. Only the use of a pressure bar to remove the mold is sufficient. However, when the depth is more than 0.5 meters, in spite of the template planer and the brush release agent, the mold opening is still very difficult, laborious and wasteful. Accidentally remove the mold, but also make the hole hole hole
