AI Technical Summary

Technical Problem

In cold environments, the uneven temperature between the inside and outside of large-volume concrete structures limits the strength development of the surface concrete and poses a risk of frost damage. Existing curing methods are energy-intensive, costly, and have long construction cycles.

Method used

The system employs a self-storage curing system, which includes a variable insulation unit, an energy storage layer, a formwork layer, and a temperature acquisition system. The central control system regulates the inflation and deflation of the variable insulation unit to maintain the energy storage and release of the energy storage layer and to uniformly control the temperature of the large-volume concrete.

Benefits of technology

This method achieves uniform temperature distribution between the interior and exterior of large-volume concrete, shortens the curing cycle, reduces energy consumption and costs, avoids frost damage, and improves construction quality and efficiency.

Abstract

The invention discloses a mass concrete self-energy-storage curing system for a low-temperature environment, which is characterized in that a central control system is used for controlling inflation and deflation of a variable heat preservation unit, so that an energy storage layer can efficiently absorb hydration heat of mass concrete in a heat preservation state; the heat can be discharged to the outside in time after the energy storage layer absorbs sufficient hydration heat, heat preservation is conducted again when the energy storage layer recovers the heat absorption capacity, the hydration heat of the mass concrete is efficiently absorbed, and in the repeated heat absorption-heat release process, the temperature difference between the surface and the interior of the mass concrete is always kept within a small range. According to the invention, hydration heat of mass concrete can be exported only by using the variable thermal insulation unit and the energy storage layer, meanwhile, the surface and internal temperatures are relatively uniform, the energy consumption, labor and materials are relatively low, and the maintenance period is shortened.
