Remote intelligent type maintenance system for prefabricated concrete components

Abstract

A remote intelligent type maintenance system for prefabricated concrete components comprises an intelligent monitoring system and maintenance system bodies. The intelligent monitoring system comprises a master monitoring device, distributed type data collecting and controlling devices, a wireless data receiving and transmitting device and a plurality of temperature sensors. Each maintenance system body is composed of a telescopic framework, heat preservation canvas, a temperature-control heating and water storing device and a spraying device. The remote intelligent type maintenance system for the prefabricated concrete components can relieve the labor intensity of workers, improve the maintenance efficiency of the prefabricated concrete components, shorten the formwork removal time of the concrete components, effectively lower the risks of cracks and other defects of the prefabricated concrete components and significantly improve the durability of concrete and has great economic and social benefits.

Description

technical field [0001] The invention is a remote intelligent concrete prefabricated component maintenance system, which is mainly used for the maintenance of concrete prefabricated components in the field. Background technique [0002] In the construction of field projects, the maintenance of prefabricated concrete components often has the following problems: under severe construction conditions, such as construction in cold seasons, it is difficult to ensure the temperature conditions required for concrete maintenance, and straw curtains and other materials are often used for insulation on site , its thermal insulation and maintenance effect is often difficult to guarantee, and it is easy to cause engineering quality accidents such as hidden dangers and delays in the construction period. Prefabricated components are prone to a large number of shrinkage or temperature cracks on the surface of the component due to excessive temperature difference between the inside and outsid...

[0002] In the construction of field projects, the maintenance of prefabricated concrete components often has the following problems: under severe construction conditions, such as construction in cold seasons, it is difficult to ensure the temperature conditions required for concrete maintenance, and straw curtains and other materials are often used for insulation on site , its thermal insulation and maintenance effect is often difficult to guarantee, and it is easy to cause engineering quality accidents such as hidden dangers and delays in the construction period. Prefabricated components are prone to a large amount of shrinkage or temperature cracks on the surface of the component due to excessive internal and external temperature differences or rapid evaporation of surface moisture, resulting in a high scrap rate

At present, most of the maintenance methods of concrete prefabricated components in the field are carried out by manual watering. On the one hand, the maintenance quality of manual watering varies from person to person, and it cannot be implemented all-weather; Man-made quality accidents such as cracking due to excessive temperature difference between curing water and concrete surface
