摘要
某加油站为满足使用要求,需对建筑物进行整体加高改造。施工中用电动液压千斤顶作为顶升动力,以螺旋千斤顶作为顶升转换安全保护的支承,采用分级同步技术保证顶升过程中上部结构的整体稳定,将所有柱子完全截断后顶升,达到预定高度后再进行修复,实现了对建筑物整体加高改造的目标。
In order to satisfy the functional requirements of a filling station,building will be integrally heightened.During the construction,electric hydraulic jack is used to provide raising force and screw jack is used as the support for raising transition safety protection.Hierarchical synchronization techniques are adopted to guarantee integral stability of the medium and upper parts of the building during raising.All columns are cut off before raising and are repaired when the building reaches the planned height,so as to realize the purpose to integrally heighten the building.
