Abstract

The invention relates to the technical field of tunnel lining curing and provides a tunnel lining concrete curing construction process. According to the process, a tunnel lining is axially divided into multiple to-be-cured segments, each to-be-cured segment is divided into multiple to-be-cured areas, curing operation including monitoring the temperature and the humidity of each to-be-cured area is performed on all the to-be-cured segments one by one, and each to-be-cured area is subjected to spraying treatment and thermal radiation treatment to enable the temperature and the humidity of each to-be-cured area to conform to a set temperature variation curve and a set humidity variation curve. The curing process can realize intelligent control on temperature and humidity, two curing ways of heating and humidifying are independent from each other, temperature curing conditions and humidity curing conditions do not affect each other, and accordingly accurate control on the temperature and humidity of each area is realized according to different demands of different areas, and tunnel lining quality, concrete strength and surface compactness can be improved significantly.

Description

technical field [0001] The invention relates to the technical field of tunnel lining maintenance, in particular to a tunnel lining concrete maintenance construction technology. Background technique [0002] At present, in the construction of domestic tunnels, the lining generally adopts natural maintenance, and very few projects adopt simple water spraying maintenance. Since the above maintenance methods are greatly affected by the external environment and human factors, the maintenance effect is not good, and it is difficult to guarantee the quality and service life of the lining. Contents of the invention [0003] (1) Technical problems to be solved [0004] The object of the present invention is to provide a maintenance process capable of significantly improving the quality of tunnel lining. [0005] (2) Technical solutions [0006] In order to achieve the above purpose, the present invention provides a tunnel lining concrete maintenance construction process, which d...
