某储罐顶升纠偏工程实例分析

CASE ANALYSIS OF A TANK LIFTING CORRECTION PROJECT

近年来由于地球进入湿润期,中国北方城市降水量明显增多,特别是对湿陷性黄土区域建筑造成很多影响。以陕西省某储罐顶升纠偏为例,针对2号水泥库周边地面出现裂缝、西侧排水渠混凝土盖板因受挤压变形出现断裂、库侧钢结构支撑点脱落、钢平台局部变形等现象,从土方开挖及护坡及钢管预压桩基础托换施工进行优化调整,加固后满足设计及规范要求,以期为类似工程顶升纠偏方案选择提供参考。

In recent years,due to the Earth entering a wet period,the precipitation in northern Chinese cities has significantly increased,especially affecting buildings in areas with collapsible loess.Taking the lifting and correction of a storage tank in Shaanxi Province as an example,in response to the occurrence of cracks on the ground around the No.2 cement warehouse,the fracture of the concrete cover plate of the west drainage channel due to compression deformation,the detachment of the steel structure support points on the warehouse side,and the local deformation of the steel platform,optimization and adjustment were carried out from earthwork excavation,slope protection,and steel pipe preloading pile foundation replacement construction.After reinforcement,the design and specification requirements were met,in order to provide reference for the selection of lifting and correction schemes for similar projects.
