Abstract

The invention discloses a mass concrete temperature intelligent monitoring and controlling device, which comprises a circulating pipeline formed by sequentially connecting a water supply device, a water distribution device, a concrete cooling system and a water return device, wherein the concrete cooling system is internally provided with a temperature monitoring device; and a centralized controlsystem which is respectively connected with the water supply device, the water distribution device, the concrete cooling system and the water return device. The concrete cooling system comprises a cooling water pipe arranged in the concrete. Usage of the device comprises a concrete cooling system setting step, a monitoring device setting step, a water distribution device setting step, a water supply device setting step, a water return device setting step, a mass concrete construction preparation step, a data acquisition step, a water supply pressure stabilization step, an alarm step, a hot water tank drainage step and a cold water tank water replenishing step. By the adoption of the mass concrete temperature intelligent monitoring and controlling device, water supply pressure can be stabilized, different water inlet temperatures and flow rates of each layer can be dynamically adjusted, temperature field change in the mass concrete can be developed according to a target of temperature control, and an alarm function is equipped, so that the problems that a temperature difference of each region of the mass concrete is too large and cracks are easy to generate are solved.

Description

technical field [0001] The invention relates to the field of concrete temperature control, in particular to a large-volume concrete temperature intelligent monitoring and control device and method. Background technique [0002] Mass concrete temperature crack control is one of the common problems in the field of civil engineering. During the construction of mass concrete structures, the hydration reaction of cement will generate a large amount of heat of hydration, which will increase the internal temperature of the concrete. When the temperature rise reaches the peak value, the temperature will drop. Uniform temperature field, the external cold concrete is constrained by the expansion and contraction of the internal hot concrete, resulting in temperature stress, when the stress exceeds the ultimate tensile strength of the concrete, the concrete will crack, resulting in the load capacity, waterproof performance and durability of the mass concrete The performance is reduced,...
