浅谈路基挖方施工方法及注意事项（The construction method of subgrade excavation and precautions） The construction method of subgrade excavation and precautions Jin Ping song (Heilongjiang Municipal Rail Transit Engineering Co., Ltd., Heilongjiang, Harbin 150000, China) Abstract: with the improvement of highway grade, the development of high-grade highway requires more and more high quality of subgrade. The roadbed construction methods together directly To the construction schedule and quality of the project. This paper discusses the following construction of excavated roadbed. [Key words] subgrade excavation; construction; precautions I. Introduction With the increase of highway grade, the development of high-grade highway and the quality of Subgrade Quantity requirements are getting higher and higher. The excavated roadbed is an important part of Subgrade Engineering As the saying goes, cut paths through mountains water bypass, since ancient times, people on the show In the long evolution of very great importance to. The excavated roadbed has its distinctive characteristics, subgrade The disease occurs mostly in the excavation area, such as landslide, collapse, fall Stone, subgrade boiling etc.. If the construction plan is not rational, the slope is too steep to abandon We piled up too close, grass planting, pavement paving and retaining wall construction is not timely, row Bad water can cause cutting slope instability, landslide, and even affect the whole A project schedule, which is often a problem in the construction of subgrade excavation. Accordingly Understanding these features so as to carry out a full range of management of subgrade excavation engineering. subgrade The construction method of excavation is directly related to the construction schedule and project quality. This paper On the application of subgrade excavation work under discussion. Two, the roadbed construction preparation before 1, measuring lofting The Contractor shall carry out the construction according to
