Mass concrete temperature control automatic integrated system

Abstract

The invention provides a mass concrete temperature control automatic integrated system. The mass concrete temperature control automatic integrated system comprises master control equipment, a pipelineassembly, a temperature measuring assembly and a cooling assembly. The input end of the master control equipment is electrically connected with the temperature measuring assembly, the output end of the master control equipment is electrically connected with the cooling assembly, and the cooling assembly controls on-off and opening degree of the pipeline assembly. The pipeline assembly consists ofa plurality of cooling pipes, each cooling pipe comprises an air cooling pipe and a water cooling pipe, the flow directions of the air cooling pipes and the water cooling pipes are opposite, and theproblem that cooling in the same horizontal layer is not uniform and asymmetric is effectively avoided. The cooling assembly comprises air cooling equipment and a circulating cooling water system, andthe air cooling equipment communicates with the air cooling pipes. The circulating cooling water system comprises a circulating cooling water tank, a variable-frequency water pump and adjusting valves arranged on the air cooling pipes and the water cooling pipes, the variable-frequency water pump and the adjusting valves are electrically connected with the master control equipment, and the mastercontrol equipment adjusts the ventilation quantity and / or water flow of the air cooling pipes and the water cooling pipes according to the temperature of the temperature measuring assemblies and controls concrete circulating cooling.

Description

technical field [0001] The invention relates to the technical field of large-volume concrete construction, in particular to an automatic integrated temperature control system for large-volume concrete. Background technique [0002] Due to the rapid development of construction projects, mass concrete construction has become more and more common, but the prevention and control of mass concrete cracks has always been the focus and problem in the industry. From the maintenance stage, the most effective way to prevent cracks in mass concrete is to pre-embed cooling water pipes, so that the temperature difference between the inside and outside of mass concrete can be controlled within a reasonable range, reducing temperature stress and preventing cracks; Shrinkage cracks are produced. [0003] At present, mass concrete construction mostly uses manual cooling water circulation and manual watering to control the temperature of mass concrete. Obviously, this traditional constructio...

Problems solved by technology

Obviously, this traditional construction method is cumbersome and requires a lot of manual labor to repeatedly carry out cooling water circulation and watering maintenance, causing a lot of waste of water resources; The large deviation of the design state leads to the "four major" problems of temperature control construction, namely: large temperature difference, large cooling range, large cooling rate, and large temperature gradient, which eventually lead to concrete cracks
