超长超深铁水倒罐坑施工技术

Super long and deep molten iron pouring construction technique

针对某炼钢厂铁水倒罐坑的施工难点,提出了5种施工方案,通过对5种方案的比较,确定采用间断排桩内支撑支护、半逆作法施工方案,详细介绍了铁水倒罐坑的施工流程及其施工要点,指出该方案既缩短了工期,又降低了成本,值得推广使用。

Aiming at the construction difficulties of one steel-making plant pouring, it puts forward five construction programs. And through comparing them, it decides the construction of using discontinuous arranging piles inner supporting and semi-inverse method, introduces the construction process and points of molten iron pouring, and points out that the program shortens the time limit of the project, and decreases the costs, and it values to prompting and application.
