我厂扩建的φ4×79米焙烧窑,四个大型窑墩均座落在老混凝土基础上。原设计需要将老基础拆除,仅拆除混凝土量就有1350米~3,又由于相邻2号焙烧窑正在生产,给施工带来极大困难,最后决定在老混凝土基础上作环氧砂浆结构钢筋锚固,这较原设计方案少拆除1100米~3混凝土,少浇灌混凝土710米~3,节省投资8.8万元,并大大缩短了工期。图 The φ4×79 m roasting kiln that our factory expanded, four large kiln piers are all located on the old concrete foundation. The original design required the dismantling of the old foundation, and only the demolition of concrete amounted to 1350 m~3. Since the adjacent No. 2 roaster was in production, it caused great difficulties in construction. It was decided to make the epoxy mortar structure on the old concrete foundation. Reinforced steel anchors, which remove 1100 m~3 concrete less than the original design, less watered concrete 710 m~3, save investment 88,000 yuan, and greatly shortened the construction period.
