Thin-layer wet joint winter construction heat preservation method
The invention discloses a thin-layer wet joint winter construction heat preservation method which comprises the steps that S1, steel beam installation is conducted, specifically, prefabricated steel box beams and steel cross beams are hoisted to bridge piers and assembled and fixed to form steel beams, and bridge deck slabs are hoisted to the steel beams; s2, a plurality of monitoring points are arranged on the bottom layer of the thin-layer wet joint, and the temperature of the thin-layer wet joint is detected; s3, a water retention film is arranged on the upper surface of the thin-layer wet joint, a maintenance space is defined on the surface of the thin-layer wet joint, and two steam-curing machines are arranged on the bridge floor and communicate with the maintenance space; s4, thin-layer wet joint pouring is conducted, specifically, thin-layer wet joints are formed between the bridge deck slabs through pouring; and S5, steam curing is conducted, specifically, high-temperature steam is conveyed into the curing space through a pipeline to conduct curing on the thin-layer wet joint, after curing is completed, the steam curing machine is turned off, the curing devices are sequentially dismantled, and grouting is conducted. The construction problem of the thin-layer wet joint is solved, the method can be well applied to the construction environment in winter, and the maintenance efficiency and quality can be effectively improved.
本发明公开了一种薄层湿接缝冬季施工保温方法，包括：S1：钢梁安装：将预制的钢箱梁和钢横梁吊装至桥墩，并进行组装固定形成钢梁，吊装桥面板至钢梁上；S2：在薄层湿接缝底层设置若干个监控点，检测薄层湿接缝温度；S3：在薄层湿接缝上表面布置保水膜，在薄层湿接缝表面围设形成养护空间，在桥面安置两台蒸养机并与养护空间连通；S4：薄层湿接缝浇筑：在桥面板之间浇筑形成薄层湿接缝；S5：蒸汽养护：通过管道将高温蒸汽输送至养护空间内对薄层湿接缝进行养护，养护完成后，关闭蒸养机，依次拆除养护装置，并注浆。本发明解决了薄层湿接缝的施工问题，可较好的应用于冬季施工环境，可有效提高养护的效率和质量。
