哈大客运专线属国家重点铁路建设项目,工期要求紧,那么如何确保在十分恶劣的低温环境下按期保质地架设900吨预制箱梁,成为制约施工进度的瓶颈,而在此过程中,如何在低温环境下控制支座灌浆料的施工质量则成为施工的关键点。为此,我们针对低温型桥梁支座灌浆料进行了深入研发和科学制备,同时制定了一套严格模拟现场的进场检验方案,再配以成本很低而行之有效的现场施工流程,最终确保了冬季施工的正常进度。 Harbin-Dalian Passenger Dedicated Line is a national key railway construction project with tight schedule requirements. How to ensure that 900 tons of prefabricated box girders are erected and maintained on a regular basis in a very poor low-temperature environment has become a bottleneck restricting the progress of construction. In the process, The construction quality of control support grouting material under the low temperature environment becomes the key point of construction. To this end, we have carried out in-depth research and scientific preparation of low-temperature bridge bearing grouting material, and at the same time, formulated a rigorous simulation of the scene approach inspection program, coupled with low cost and effective on-site construction process, and ultimately To ensure the normal progress of construction in winter.
