摘要
文中以湖北省秭归县茅坪河流域综合治理生态廊道建设工程为例,重点研究了公路路基工程挡土墙施工技术,总结了工程中块石与混凝土的原材料控制要点,并从技术要求及参数、施工流程、片石基础施工、片石墙身施工、泄水孔设置、沉降缝设置、裂缝控制七个环节对施工技术展开分析,通过对挡土墙的质量检验,确定其施工效果较好,可为类似项目提供参考.
Abstract
Taking the comprehensive management ecological corridor construction project in Maoping River Basin,Zigui County,Hubei Prov-ince as an example,this article focuses on the construction technology of retaining walls for highway subgrade engineering.The key points of raw material control for block stones and concrete in the project are summarized in detail,and the construction technology is analyzed from sev-en aspects:technical requirements and parameters,construction process,construction of stone foundation,construction of stone wall body,set-ting of drainage holes,setting of settlement joints,and crack control.Through quality inspection of retaining walls,it can be determined that their construction effect is good,which can provide useful reference for similar projects.
