Description
Technical Field
The invention relates to a concrete curing device, in particular to a curing shield for winter curing of a railway pier.
Background
In the field of current infrastructure construction, pier body maintenance construction is very common, the maintenance method is relatively single, watering maintenance is mostly carried out by winding plastic films or geotextiles, labor and materials are more in the method, winding plastic films (geotextiles) and watering operation are difficult, pier body maintenance effect is difficult to accurately master in maintenance construction, and concrete compressive strength is one of important mechanical properties of concrete. The increase of concrete strength is not only related to raw materials and pouring and tamping processes, but also has a direct relation with the curing conditions of the concrete. The process of increasing the strength of the concrete is essentially the result of hydration of the cementitious material. Hydration occurs normally and is closely related to the environmental conditions in which the concrete is exposed. The environmental conditions here mean both temperature and humidity. When the temperature is lower than a certain limit value, the cement hydration reaction can not be carried out, and the concrete strength stops developing, and the temperature is generally about-10 ℃. In fact, at temperatures below 0 ℃, the water in the concrete already starts to partially freeze, which will lead to freezing damage to the concrete. When the concrete structure is in a dry environment, the necessary water is lacked during hydration, and the water of combination cannot be guaranteed, the action speed is slowed down or stopped, and the strength of the concrete is finally influenced, so that the proper temperature and sufficient humidity are kept during the concrete curing period. However, during construction in winter, due to the influence of the external environment, the curing after concrete construction generally adopts the erection of a shed frame for steam curing or the brush coating of a curing agent.
