市政路桥工程大体积混凝土施工技术分析

Analysis of Mass Concrete Construction Technology of Municipal Road and Bridge Engineering

在市政路桥工程施工中,大体积混凝土施工技术得到广泛应用。但是,受到水泥水化热、外界气温变化、混凝土收缩变形等多重因素的影响,混凝土常常出现裂缝,甚至还会引发交通安全事故。基于此,施工单位在进驻施工现场之前,需要制定一套科学系统的混凝土施工方案,并通过方案的有效实施来改善和提高大体积混凝土施工质量。本文将着重围绕市政路桥工程大体积混凝土施工技术要点予以阐述,并针对施工质量提出有效的技术与管理措施。

In the construction of municipal road and bridge engineering,mass concrete construction technology has been widely used.However,due to multiple factors such as cement hydration heat,changes in external temperature,and shrinkage and deformation of concrete,the concrete cracks often appear,and even traffic safety accidents may occur.Based on this condition,the construction unit needs to formulate a set of scientific and systematic concrete construction plan before entering the construction site,and improve and enhance the mass concrete construction quality through the effective implementation of the plan.This paper will expound the key points of mass concrete construction technology of municipal road and bridge engineering,and put forward effective technical and management measures for construction quality.
