高速铁路路基接触网支柱基础施工关键技术

随着我国铁路的迅速发展,尤其是高速铁路的发展,对铁路接触网的要求越来越高,作为接触网基础的施工也越来越受到高度重视,而接触网支柱预埋螺栓的固定尤为重要,直接关系到接触网支柱能否准确就位、受力是否合理。结合贵广铁路接触网支柱基础施工,重点介绍了接触网支柱基础预埋螺栓采用双层模具固定法施工控制关键技术,采用该施工技术,满足了设计和验标的要求。

Key Technique of Catenary Mast in Foundation Construction of High-speed Railway Subgrade

With the rapid development of China＇s railway, especially the development of high-speed railway, the railway overhead catenary system has the increasingly high demand, the foundation construction is also more and more high importance, and pre-buried bolt fixed of catenary mast is particularly important, which is directly related to the catenary mast＇s accuracy and its stress reasonable. Combined with the construction of Guiyang-Guangzhou Railway catenary mast foundation, the paper introduces the key control construction technology of pre-buried bolt using the double mould fixing method , which satisfies the design and standard requirements.
