高速公路改扩建工程中路基施工的质量好坏直接影响到整个工程项目的质量,所以在路基施工过程中必须坚持技术先进性、管理科学性、经济实用性与实事求是相结合的原则,选择合理的施工方案,保证工程施工进度,确保施工质量。本文以沈铁公路改扩建工程开原至昌图段为例,探讨高速公路改扩建工程施工质量提升的方法。路基填料要求路基填料中严禁使用泥炭、淤泥、冻土、强膨胀土、有机土及溶岩含量超标的土填筑路基。
In highway reconstruction and expansion project, the quality of roadbed construction has a direct impact on the quality of the whole project. Therefore, in the process of subgrade construction, we must adhere to the principle of combining technology advancement, management science, economy practicability and seeking truth from facts, and choose reasonable Construction program to ensure construction progress, to ensure construction quality. This paper takes Shen-Chang-Chang-Tuan Section of Shen-Tui Highway Reconstruction and Extension Project as an example to discuss the method of improving construction quality of expressway reconstruction project. Subgrade filling requirements Subgrade filler is prohibited to use peat, silt, frozen soil, strong expansive soil, organic soil and dissolved rock content of soil overburden embankment.
