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。
With the rapid development of China’s railways, especially the development of high-speed railway, the requirements on the railway catenary are getting higher and higher, and the construction as the foundation of the catenary is also paid more and more attention. The fixing of the embedded bolts of catenary pillars is especially Important, directly related to the network of pillars can be accurately placed in place, the force is reasonable. Combined with the construction of the catenary support of the catenary of Gui - Guang Railroad, the key technologies of the construction control of the embedded bolts of the catenary strut base with double - layer mold are introduced emphatically. The construction technology is adopted to meet the requirements of design and verification.
