公路工程混凝土灌砌块石挡土墙施工技术研究

Study on Construction Technology of Concrete Block Stone Retaining Wall in Highway Projects

浆砌片石和片石混凝土技术已广泛应用于公路工程中的挡土墙等,具有完整的施工工艺与技术标准。但因片石混凝土施工建造费用高,浆砌片石施工质量控制难而难以推广。以351国道公路工程为例,介绍了混凝土灌砌块石挡土墙技术在公路工程中的具体应用,分析了混凝土灌砌块石挡土墙采取的施工工艺及带来的效益,可为类似工程施工提供参考。

Mortar rubble and rubble concrete technology has been widely used in the retaining wall of highway projects,and it has complete construction technology and technical standards.However,due to the high construction cost of rubble concrete construction,and the difficulty of quality control of mortar rubble construction,both are difficult to promote.Taking 351 national highway as an example,this paper introduces the specific application of concrete block stone retaining wall technology in highway projects,analyzes the construction technology and benefits of concrete block stone retaining wall,which can provide reference for the construction of similar projects.
