大容量接触网钢柱基础地脚螺栓预埋和精度控制

Pre Embedding and Precision Control of Anchor Bolts for Steel Column Foundation of Large Capacity Contact Network

在铁路电气化改造工程中,有的地段需要采用大容量接触网钢柱,如果其基础地脚螺栓预埋产生偏移或精度不够,将会影响大容量钢柱的组立和施工效率。此文以滨洲铁路电气化改造工程为例,探讨大容量接触网钢柱基础地脚螺栓的预埋和精度控制问题。

Large capacity catenary steel columns need to be used in some sections of the railway electrification trans- formation project. And the pre embedding and precision control of foundation bolts will affect the forma- tion and construction efficiency of large capacity steel columns. Taking the electrification engineering of Haerbin - Manzhouli railway as an example, the problem of pre embedding and precision control of an- chor bolts for steel column foundation of large capacity catenary is analyzed.
