近年来随着我国石油和天然气产量的不断增长,大型球罐的使用越来越普遍,而有时为了施工的需要,对于大型球罐进行整体的调运移位是不可避免的过程。而整体调运移位施工过程是在一定的范围内实施,使其完整的保留下来,取得理想的效果,其经济效益十分明显。采用托换技术和液压推进系统为大型球罐整体调运移位技术的推广应用提供了条件。 In recent years, as China’s oil and gas production continues to grow, the use of large-scale spherical tank more and more common, and sometimes for the construction needs, for large spherical tank relocation of the overall transfer is an inevitable process. The overall transfer of displacement construction process is implemented within a certain range, so that it remains intact, and achieved the desired results, the economic benefits are obvious. Adopting underpinning technology and hydraulic propulsion system provided the conditions for the popularization and application of the whole transportation and displacement technology of large spherical tank.
