Winter construction maintenance method for bridge expansion joint
The invention discloses a winter construction maintenance method for a bridge expansion joint, which comprises the following steps of: paving an electric heat tracing wire in expansion joint concrete in advance, and switching on the electric heat tracing wire after the concrete is poured; setting up a totally-enclosed warm shed on the top surface; heating equipment is cooperatively used in the warm shed to heat the warm shed; a temperature and humidity monitoring device is arranged in the warm shed to conduct temperature measurement and monitoring regularly, a temperature control meter and a temperature sensor are arranged on a loop of each electric heat tracing wire, the temperature sensors can be embedded in expansion joint concrete, and the temperature of the temperature control meters is set at the temperature value meeting the concrete curing requirement. The output power can be automatically adjusted along with the temperature of the electric tracing wire. The fully-closed warm shed is simple, efficient and low in manufacturing cost, the problem that an electric blanket is adopted in traditional winter construction is solved while the expansion joint concrete curing quality is effectively guaranteed, the construction cost is reduced while the construction safety is improved, and the probability of quality problems is reduced.
本发明公开了一种桥梁伸缩缝的冬期施工养生方法，包括以下步骤：伸缩缝砼内提前铺设电伴热线，并在砼浇筑完成后接通电伴热线；在顶面搭设全封闭的暖棚；暖棚内配合使用加热设备对暖棚进行加热；暖棚内设置有温湿度监控设备定时进行测温监控，各所述电伴热线的回路上均设置有温控表及温度传感器，所述温度传感器可埋置在伸缩缝混凝土里面，将温控表的温度设定在满足混凝土养生要求的温度值，使其输出的功率可随电伴热线温度自动调整。本发明采用的全封闭暖棚具有简易、高效、造价低廉，在有效保证伸缩缝混凝土养生质量的同时解决了传统冬季施工中采用电热毯的做法，提高施工安全性的同时降低施工成本，减少质量问题出现的概率。
