The utility model discloses a digital thermostatic control concrete ultra-low temperature construction curing system which comprises a sliding formwork, a data collecting device, a wireless transmission device and a warming-up control device, wherein a thermal insulation shed is mounted on the circumference of the sliding formwork, a steel pipe suspension bracket is mounted at the lower part of the sliding formwork, four electron heating quilts are suspended on the steel pipe suspension bracket, and the four electron heating are surrounded by a barrel-shaped airtight heat preservation cover; each electron heating quilt comprises a high-strength glass fiber layer, a heat tracing belt and a heat insulation cotton layer which are connected in sequence from the inner out; and a plurality of temperature sensors are mounted on each electron heating quilt, and the temperature sensor and the heat tracing belt are respectively connected with the data collecting device, the wireless transmission device and the warming-up control device. The digital thermostatic control concrete ultra-low temperature construction curing system takes favorable heating and thermal insulating effects, and can effectively prevent heat dissipation during concrete casting. When the environmental temperature is 30 DEG below zero, the temperature of the concrete surface is guaranteed to be more than five DEG. Therefore, freezing injury and cracks on the surface of the concrete can be prevented, and the casting quality of a bridge pier can be ensured.
