A large-volume concrete temperature control automatic integrated system

Abstract

The present invention proposes a large-volume concrete temperature control automatic integrated system, including general control equipment, pipeline components, temperature measurement components and cooling components, the input end of the general control equipment is electrically connected to the temperature measurement component, and its output terminal is connected to the cooling component Electric connection, the cooling component controls the on-off and opening of the pipeline component; the pipeline component is composed of several cooling tubes, each cooling tube includes an air-cooled tube and a water-cooled tube, and the flow directions of the air-cooled tube and the water-cooled tube are opposite. Effectively avoid the problem of uneven and asymmetric cooling in the same horizontal layer; the cooling components include air cooling equipment and a circulating cooling water system, and the air cooling equipment is connected to air cooling pipes; the circulating cooling water system includes circulating cooling water tanks, variable frequency water pumps and The regulating valves arranged on the air-cooling pipes and the water-cooling pipes, the variable-frequency water pump and the regulating valves are electrically connected to the general control equipment, and the general control equipment adjusts the ventilation volume and / or Or water flow, cooling control of concrete circulation.

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
