速凝混凝土在道路快速抢修中的应用

Application of Quick-setting Concrete in Quick Repair of Road

随着城市面积扩大,各种基础设施也要不断完善。自来水、电力、燃气、热力、通讯、排污等基础设施穿插、挖掘、破坏原有路面,如果利用普通材料修复路面用时长,被管制路段安全隐患多。如何安全、快速完成路面修复,关系到养护工作的效率和公路通行服务能力的提升。实践中用速凝混凝土作为路基层,用桥梁伸缩缝锚固材料,作为水泥混凝土路面快速修补材料,都大大提高了工作效率,具有推广意义。

With the expansion of urban area,all kinds of infrastructure should be constantly improved.With the expansion of infrastructure such as tap water,electricity,gas,heat,communication and sewage,it brings about interpenetration,excavation and destruction of the original road surface,and the use of ordinary materials to repair the road surface takes a long time,the open traffic time is long,and the controlled road sections have many hidden dangers.How to finish road repair safely and quickly is related to the efficiency of maintenance work and the improvement of road service capacity.In practice,the use of quick-setting concrete as road base,as anchorage material of bridge expansion joint,as quick repair material of cement concrete pavement,has achieved good working efficiency,and has popularization significance.
