路桥施工中大体积混凝土裂缝成因与防治措施

Causes and Prevention Measures of Mass Concrete Cracks in Road and Bridge Construction

近年来,在各方面利好因素的带动下,使得我国综合国力得到了显著的提升,从而为我国城市化建设工作的全面推进打下了坚实的基础。在城市化建设中,路桥工程是其中最为重要的一个部分,而在路桥工程施工中使用最为频繁的就是混凝土物料。混凝土结构因为施工材料自身具有一定的特殊性,所以极易受到外界各种不良因素的影响,在浇筑硬化之后往往会在结构中产生诸多的气孔或者是微裂缝,如果这些问题不能有效的加以解决,那么必然会对混凝土结构质量造成严重的损害。在实施路桥工程施工工作的时候,如果存在原材料质量不达标,混凝土浇筑流程不合理,后期养护工作不充分等诸多问题,那么都会对大体积混凝土结构质量造成严重的损害,甚至会引发质量事故的发生,所以一线工程施工工作人员需要拥有良好的质量安全责任理念,严格遵照规范标准落实各项施工工作,确切的保证工程施工质量和效果。

In recent years,driven by various favorable factors,China's comprehensive national strength has been significantly improved,thus laying a solid foundation for the comprehensive promotion of China's urbanization.In the process of urbanization,road and bridge engineering is one of the most important parts,and concrete materials are used most frequently in road and bridge construction.Because of the particularity of construction materials,concrete structure is easily affected by various external factors.After pouring and hardening,there are many pores or cracks in the structure.If these problems can not be effectively solved,it will inevitably cause serious damage to the quality of concrete structure.In the implementation of road and bridge engineering construction,if there are many problems,such as the quality of raw materials is not up to standard,the concrete pouring process is not reasonable,and the later maintenance work is not enough,it will cause serious damage to the quality of mass concrete structure,and even cause dangerous accidents.Therefore,the construction workers of the first-line project need to have a good quality and safety responsibility concept,strictly follow the norms and standards to implement all construction work,and ensure the quality and effect of the project construction.
