When the support form of the deep foundation pit adopts concrete internal support, the cross-sectional size of the concrete internal support beam is greater than 1000mm×1000mm, which belongs to large-volume concrete. In order to ensure the safety during the foundation pit excavation process, there are higher requirements for the pouring and maintenance of the concrete internal support beam.

[0003] Concrete curing methods at construction sites include watering curing and continuous watering. Among them, watering curing is to cover the concrete surface with a layer of straw mats or sacks, and then frequently spray clean water on the surface to keep it moist. This method is suitable for environments with high temperatures and strong winds. The continuous watering method is to keep the concrete surface moist by continuously watering it. It is suitable for the curing of small areas and shallow layers of concrete. It is necessary to keep the water flow uniform to avoid scouring damage caused by local over-humidity or excessive water flow. The labor cost of existing construction site concrete curing is high.
