市政道路隧道工程施工中的难点和技术对策

Difficulties and Technical Countermeasures in Municipal Road Tunnel Construction

随着交通事业的不断发展,城市道路桥梁隧道建设规模不断扩大。隧道施工具有很强的隐蔽性以及高难度的特点,在施工过程中对技术人员以及工艺操作提出更高的要求。一旦操作不规范会造成技术上不达标甚至更加严重的安全事故。通过对目前市政道路隧道施工现状的调查,普遍存在钢筋防腐操作不规范、混凝土结构开裂等问题,需要采取有效的技术措施进行防护。文章围绕市政道路隧道施工中的技术难点进行讨论,着重分析技术措施,仅供参考。

With the continuous development of transportation,the construction scale of urban road,bridge and tunnel is expanding.Tunnel construction has the characteristics of strong concealment and high difficulty,which puts forward higher requirements for technicians and process operation in the construction process.Once the operation is not standardized,it will lead to technical non-compliance and even more serious safety accidents.Through the investigation of the current construction situation of municipal road tunnel,there are common problems such as non-standard anti-corrosion operation of reinforcement and cracking of concrete structure,which need to take effective technical measures for protection.This paper discusses the technical difficulties in the construction of municipal road tunnel,and focuses on the analysis of technical measures for reference only.
