以往在进行大型动力设备基础找正和找平时,均需采用垫铁的方法来调整,要耗用大量的钢材。采用无垫铁施工工艺,既节省了钢材,又简化了施工程序。本文介绍了无垫铁施工工艺并强调该工艺的技术关键——补偿收缩混凝土的配制。 In the past, when large-scale power equipment foundations were to be calibrated and leveled, they all needed to be adjusted using horns, which required a large amount of steel. The use of hornless construction technology saves steel and simplifies construction procedures. This article describes the hornless construction process and emphasizes the key technology of the process - the preparation of the compensation shrinkage concrete.
