风化岩石段接触网下部工程施工,在接触网施工中占有举足轻重的作用,风化岩石段接触网下部工程施工具有周期长,技术复杂,环境恶劣,施工难度大等特点。因此,风化岩石段的施工要做到提前介入,尽快施工,以确保整个工程施工有序的推进,施工过程中,在对施工影响进行排查的同时,例如:附近建筑物、敷设的地下管道、光电缆等,采用控制技术,对基础进行打眼,爆破施工,并对基础施工过程各项技术指标采用合理有效的方法进行控制。
Weathered rocks segment contact network construction, occupy a decisive role in the construction of the catenary. The weathering rock section of the lower part of the contact network construction has the characteristics of long cycle, complex technology, harsh environment, difficult construction. Therefore, construction of weathered rock sections should be intervened in advance and be constructed as soon as possible so as to ensure the orderly progress of the whole project construction. During the construction process, the construction impacts should be investigated, for example, nearby buildings, laid underground pipelines, Optical cables and so on, the use of control technology, the basis of drilling, blasting construction, and the basic construction process of various technical indicators using a reasonable and effective method of control.
