在高炉快速大修过程中滑移轨道梁及桩基的设计探讨

Design of Slippage Rail Beam and Pile Foundation During Rapid Overhaul of Blast Furnace

在冶金工业中,高炉快速大修的方案正在成为首选。滑移轨道梁作为高炉快速大修的一项临时设施,起着至关重要的作用。该文探究了滑移轨道梁表面的摩擦系数取值,分析了摩擦力为系统平衡力系与否的区别,并对支撑体系进行了概念探讨。建议在施工临时设施中,单桩允许最大承载力可适当放大。根据温克尔模型,可将单桩视为弹性支点进行建模计算。通过分析,建议滑移轨道梁的最大水平度控制值。

In the metallurgical industry,the rapid overhaul scheme of blast furnace is becoming the first choice.As a temporary facility for rapid overhaul of blast furnace,the slippage rail beam plays an important role.This paper explored the value of friction coefficient on the surface of the slippage rail beam,analyzed the difference between friction force and equilibrium force,and discussed the concept of support system.It is suggested that the maximum bearing capacity of a single pile can be scaled up appropriately in temporary construction facilities.According to the Winkler model,a single pile can be regarded as an elastic fulcrum for modeling and calculation.Through the analysis,it is suggested to adopt the maximum levelness control value of the slippage rail beam.
