Problems solved by technology

[0003] For areas where the climate environment is dry and the temperature difference between day and night is large, the formwork insulation system plus watering and moistening maintenance method is used to maintain heat preservation and moisture retention. The fundamental defect is that the water loss on the concrete surface is fast, and the surface humidity and humidity uniformity are difficult to guarantee. In addition, the insulation effect of the formwork insulation system Poor, not conducive to the control of temperature difference between inside and outside

Abstract

The invention relates to a long-wall structure concrete curing device and a curing method thereof. The curing device comprises a moisturizing device, a heat-preservation device and a temperature measurement device, wherein the moisturizing device comprises a spraying pipe, and the spraying pipe is fixed through a split bolt of a formwork at the top of a wall; the heat-preservation device comprises a plastic film and a heat-preservation material, the spraying pipe and the wall are wrapped with the plastic film, and the plastic film is wrapped with the heat-preservation material; the temperature measurement device comprises a center temperature measurement point and a surface temperature measurement point, the center temperature measurement point and the surface temperature measurement point are buried at the same elevation of the wall, and the center temperature measurement point and the surface temperature measurement point are connected with a numerical control temperature measurement instrument through a temperature measurement line. According to the curing device and the curing method, the outside of the surface of a long-wall concrete structure is provided with the moisturizing device capable of spraying fine water mist slowly and wrapped with the heat-preservatoin device composing of the plastic film and the heat-preservation material, the difference of temperatures inside and outside concrete is controlled, temperature stress in the concrete is reduced, temperature cracks of the concrete are reduced, and the problem of how to control the cracks in long-wall structure construction in the environment with a dry climate and a large temperature difference is solved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a long wall structure concrete maintenance device and a maintenance method thereof. Background technique [0002] During the construction of concrete structures, due to the temperature difference between the interior and exterior of the concrete and the existence of the structural boundary constraint system, a series of temperature stresses are generated inside the structure. When the temperature stress is greater than the tensile strength of the concrete, concrete cracks will occur. The greater the temperature stress The larger the crack width is. Under general construction conditions, the temperature stress of concrete is closely related to the pouring length of the concrete body (expansion joint spacing), the thickness of the concrete, and the constraint conditions of the boundary. The maximum length of the pouring body (that is, the expansion joint spacing), the structu...
