高寒地区冬期预制梁施工技术探讨

冬期施工已不乏其例,但国内在高寒地区进行预制梁冬期施工的成功案例比较少。通过对青海省德令哈制梁场冬期制梁施工的总结,研究原材料、混凝土搅拌、混凝土灌注、梁体养护的加热和保温措施,提出了后期配套措施的保温等问题,获得了一套在高寒地区现场预制梁的冬期施工技术。

Application of prefabricated beam construction technology in alpine-cold region

There are many cases of winter construction, but there are not many successful cases of winter construction of prefabricated beams in alpine-cold region. Based on the summary of the winter beam-making construction in Delingha Beam-making Works, this paper studies the heating and heat preservation measures of raw materials, concrete mixing, concrete pouring and beam body maintenance, puts forward the heat preservation problems of the later supporting measures, and obtains a set of winter construction technology of field prefabricated beams in alpine-cold region.
