Abstract
Based on the actual project cases,the key construction points in the grouting of prefabricated walls in winter are discussed such as grouting material preparation,grouting time selection,grouting sleeve technology,temperature monitoring,heating and thermal insulation.The construction results are tested and analyzed.The results show that as long as the following requirements are met:the grouting material is prepared in strict accordance with the regulations;the grouting time is rationally selected,the outer eaves of the grouting joints are timely blocked and treated,the mechanical pressure grouting process is adjusted,and the measures for thermal insulation and heating are scientifically taken,the actual deviation of the installation size of the prefabricated wallboard components can be limited to the allowable range.Low temperature can be prevented from affecting the grouting construction.关键词
