The cross section of the anti-collision guardrail is small in size, large in specific surface area, slow in cement hydration heat release and fast in heat dissipation, and the anti-collision guardrail is difficult to ensure to be free from negative temperature by means of heat preservation during winter construction; the length of the anti-collision guardrail is long, the progress is accelerated by shortening the form removal time in the construction process, and the heat loss is accelerated by the early removal of the template. The top surface of the anti-collision guardrail with different anti-collision grades is 1.2-1.5 m away from the top surface of the beam, so that when concrete of the anti-collision guardrail is poured in situ in winter in the north, the abrupt members are extremely difficult to preserve heat, namely, the anti-collision guardrail is easily influenced by the negative temperature of the environment, so that the performance is poor. The concrete affected by negative temperature in the early age has obviously reduced compressive strength, and the impermeability and the frost resistance of the concrete are far lower than 1/10 of the unfrozen concrete in the early age, so that how to ensure that the anti-collision guardrail is not affected by the negative temperature is very important during winter construction, and a heat storage system for the concrete winter construction of the anti-collision guardrail needs to be developed.
