Abstract

An intelligent temperature control device for mass concrete is characterized in that an upper branch pipe and a lower branch pipe are arranged on a water segregator pipe at equal intervals, a flange plate is arranged between the upper branch pipe and the lower branch pipe, electromagnetic valves are installed on the flange plate, the branch pipes are welded to the upper branch pipe, and a safety water escape valve is arranged at the tail end of the pipe wall of the water segregator pipe. A water inlet pipe opening and a water outlet pipe opening of each layer of bent circulating water pipe pre-buried in the mass concrete bearing platform are connected with the water inlet pipe and a water inlet of the water pool respectively. A temperature measuring pipe is pre-buried between every two layers of circulating water pipes in the mass concrete bearing platform, and the temperature measuring pipes are filled with liquid medium layers. Temperature sensors pasted to the inner wall of the external environment temperature measuring pipe are inserted into the liquid medium layer, and each temperature sensor is connected with the PLC through a wire.

Description

technical field [0001] The invention relates to the field of large-volume concrete construction, in particular to an intelligent temperature control device for large-volume concrete. Background technique [0002] With the gradual increase of high-rise buildings and long-span bridges with high piers, mass concrete structures have been widely used in modern engineering construction. During the construction of mass concrete structures, the main problem encountered is temperature cracks. Due to the large volume of concrete structures, the cement generates a large amount of heat during the hydration process to increase the internal temperature of the concrete structure. When the temperature difference between the center of the concrete structure and the surface, the surface When the temperature difference from the atmosphere or the cooling rate is too large, temperature stress and temperature deformation will occur, and when the temperature stress exceeds the binding force inside...
