At present, in the design process of communication line, often encounter new lines across the railway, national highway, and according to the requirements of local road or railway management department, across the lines can't be directly spliced pole overhead, which requires using microporous pipe jacking technology to ensure the completion of the communication line. The according to the national and provincial highway route design of field survey, combined with microporous pipe jacking technology, expounds the application of microporous pipe jacking technology in the design of the communication line.%目前,在通信线路设计过程中,经常会遇到新建线路需要跨越铁路、国道的情况,而根据当地路政或者铁路管理部门的要求,线路不能直接拼接杆路架空跨越,这就需要运用微孔顶管技术来保障通信线路的完成.根据本省国道、省道线路设计的实地勘察情况,结合微孔顶管技术,阐述了微孔顶管技术在通信线路设计中的应用.
