砂砾石路基填筑施工技术

Construction Technology of Sand Gravel Subgrade Filling

在汶川映秀镇灾后重建工程中,如何保证道路工程按工期按质量完成至关重要。本文从砂砾石作为基层的材料特性和施工环境出发,通过对砂砾石路基的理论研究成果分析并结合工程实践经验,就砂砾石材料的级配要求、颗粒压碎值要求、摊铺及压实工艺、检测指标等施工技术进行了探讨,提出了砂砾石路基施工技术体系,节约成本并保证工期及质量,效果理想。

The town of Yingxiu in Wenchuan post disaster reconstruction project,how to ensure the road engineering in time according to the quality of the completion is essential. This paper from the sand and gravel material properties as a base and construction environment,through the analysis of the gravel roadbed of theoretical research results and combined with the practical engineering experience,requires,graded gravel material particle crushing value requirements,paving and compaction technology,detection index construction technology is discussed. The construction technique of roadbed gravel stone,cost savings,and ensure the construction period and quality,the ideal result was obtained in theschedule and cost control.
