Background

The high-speed railway with passenger special line has strict requirements for settlement deformation of structures, roadbeds and other projects, and has larger pressure on the second lining concrete of the tunnel due to wind tunnel effect when the high-speed running train passes through the tunnel in tunnel projects, so that the tunnel structures can meet the requirements of receiving the wind pressure when the train passes through besides the requirement of settlement deformation, and the tunnel structures are stable and the second lining surface cannot fall off when the train passes through. The tunnel secondary lining concrete is required to have enough strength and meet the durability requirement. The durability influencing factors of the tunnel concrete have an important influencing factor, namely concrete curing, besides raw materials, mixing proportion and the like. After concrete is poured, if the weather is hot, air drying is carried out, curing is not carried out in time, moisture in the concrete can evaporate too fast, dehydration phenomenon is formed, cement particles with gel can not be fully hydrated, the cement particles can not be converted into stable crystals, and the cement particles lack sufficient cohesive force, so that flaky or powdery falling off can occur on the surface of the concrete. In addition, when the concrete does not have enough strength, the premature evaporation of water can generate larger shrinkage deformation, and dry shrinkage cracks appear, so that the durability and the integrity of the concrete are affected. Therefore, after the concrete is demolished, maintenance is needed in time to keep the concrete in a wet state.
