Mass concrete intelligent curing system and curing method

Abstract

The invention discloses a mass concrete intelligent curing system. The system comprises a water permeable formwork (2) which is mounted on the periphery of mass concrete (1) and tightly attached to the side wall of the mass concrete and a temporary water-retaining wall (3) which is mounted on the periphery of the water permeable formwork (2) and spaced from the water permeable formwork (2) by a certain distance, a certain space structure is formed between the permeable formwork (2) and the temporary water-retaining wall (3), intelligent circulation curing water (4) with controllable temperature is mounted in the space structure, and the curing water (4) can submerge upper surfaces of the permeable formwork (2) and the mass concrete (1). The invention further discloses a corresponding curing method. The curing system carries out full water coverage curing on the mass concrete, the hydration heat temperature diffusion of the mass concrete can be controlled, surface shrinkage cracks of the mass concrete can be prevented, and the tedious manual intervention is reduced.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a large-volume concrete intelligent maintenance system and maintenance method. Background technique [0002] my country's "Massive Concrete Construction Standards" GB50496-2018 stipulates that the minimum geometric size of the concrete structure entity is not less than 1m large-scale concrete, or it is expected to cause harmful cracks due to temperature changes and shrinkage caused by the hydration of the cementitious material in the concrete The resulting concrete is called mass concrete. The main feature is the large size, the minimum size of the general entity is greater than or equal to 1m, its surface coefficient is relatively small, the release of cement hydration heat is relatively concentrated, and the internal temperature rises relatively quickly. When the temperature difference between the inside and outside of the concrete is large, it will cause ...

Problems solved by technology

However, there are still imperfect effects. The concrete surface requires a lot of manual intervention and timely management, and on some surfaces with reserved steel bars, it is difficult to form a good coverage protection, resulting in multiple cracks on the concrete surface, and even the temperature If the details of the control are not in place, the effect is often unsatisfactory, especially in some areas with variable cross-sections, or areas that are difficult to cover well, and shrinkage cracks appear due to the difficulty of moisturizing under the thermal insulation quilt
