Assembly Technique of Anchor Bolts for Stainless Steel Cold Rolling

酒钢不锈钢冷轧二期大冷线基础分9块,全长270 m,底部标高最深为7.6 m。基础螺栓标高大致分三层近千根,由于设备安装精度要求高,螺栓相对尺寸及总尺寸的安装精度同样要求十分严格。为了保证螺栓的安装精度,从测量控制、螺栓固定架安装、螺栓安装、混凝土浇筑等几个方面进行了严格的控制。特别是定位控制,采用长短线相结合的方法,利用全站仪进行有效的控制,满足了规范的相关规定。

The foundation of JISCO Stainless steel cold roiling project CAPL is composed of 9 pieces with total length of 270m and the deepest foundation level of 7.6m. The elevation of foundation bolts is roughly divided into three layers and the amount is nearly 1000. Due to high precision requirement to equipment installation, the installation accuracy of the rel- ative dimension and total dimension of the bolt is strictly required. In order to ensure the precision of assembling bolts, strict control should be implemented in measurements, installation of fixed frame of bolts, installation of bolts and concrete casting. Especially, the control of location, which makes use of the method of the combination of the long and short line and takes advantage of Electronic Total Station to make effective control, must conform to the regulations.
