摘要
北京通州文化旅游区日新路23号桥现浇预应力混凝土连续箱梁冬期施工中,针对传统的搭设暖棚养护质量难以控制的弊病,采用聚氨酯保温喷涂进行全封闭蓄热保温的措施进行冬期施工,该做法简单且不受支架高度和风阻的影响,保温效果良好。
During the winter construction of the cast-in-place prestressed concrete continuous box girder of No.23 Rixin Road,Tongzhou Cultural Tourism Zone,Beijing,in view of the disadvantages of traditional heating sheds that are difficult to control quality of maintenance,polyurethane thermal insulation spraying is used for fully enclosed heat storage and insulation measures for winter construction,which is simple and is not affected by height of support and wind resistance,and thermal insulation effect is good.
