Rapid electric heating single-hole box girder prefabricating method

The invention discloses a rapid electric heating single-hole box girder prefabricating method. The method is characterized in that a heating and maintenance system is adopted, and the system comprises a single-hole box girder, electric heaters, a heat insulation material and lining bodies. The method comprises the following steps that 1, the outer surface of the single-hole box girder is covered with the heat insulation material; 2, the multiple electric heaters are evenly placed into reserved positions inside the single-hole box girder; 3, the multiple layers of lining bodies are laid in holes in the two ends of the single-hole box girder; 3, water is injected into the single-hole box girder; and 5, switches of the electric heaters are turned on. 本发明公开了种快速电热单孔箱梁预制方法，其特征在于：所述方法使用的是加热养护系统，所述系统包括单孔箱梁、电热器、保温材料和砌体；该方法包括以下步骤：1)将单孔箱梁的外表面覆盖保温材料；2)将若干个电热器均匀放置在单孔箱梁内部的预留位置处；3)在单孔箱梁的两端洞口处砌筑若干层砌体；4)在单孔箱梁内部注水；5)开通电热器的开关。
