Description
Technical field
The present invention relates to concrete curing technical fields, more particularly to a kind of tunnel double-lining vault and abutment wall sealed maintenance
Device and method.
Background technology
Lining cutting is the important engineering measure for balancing surrouding rock stress, extending tunnel service life, ensureing safe operation.
With the technological progress of Tunnel Engineering, for tunnel-liner technology, initial stage combined bolting and shotcrete+flexibility is used comprehensively
The composite lining structure that waterproof layer+armored concrete two serves as a contrast, construction method is also by full section face (vault and side wall) lining trolley+pump
Concrete making technology is sent, instead of the lining methods of arch-wall method+small template assembly+artificial loading, construction efficiency is substantially carried
It rises.
Maintenance is one of important procedure of concrete construction, currently, there are commonly watering covering, curing agent spraying and steam
The methods of health.
After concrete casting complete, concrete carries out hydration reaction (cement granules are converted to crystallization) under static state,
Concrete gradually hardens (intensity gradually increases) under hydration, and early strength of concrete growth rate is very fast, later strength
Growth rate is gradually reduced.
Moisture in concrete proportioning is the primary condition for completing hydration reaction, and watering maintenance is for concrete component table
Face provides high humidity environment, concrete can be effectively prevent to be dehydrated, ensure that the abundant aquation of concrete, to ensure concrete most
Whole intensity；Spraying curing agent closes surface of concrete structure, can also concrete be effectively prevent to be dehydrated, and ensures concrete
Abundant aquation, to ensure concrete final strength；Steam curing is to provide high humility and higher temperatures simultaneously for concrete component
The environment of degree ensure that the abundant aquation of concrete also speeded up hydration reaction while ensure that concrete final strength
Speed can quickly improve the intensity of concrete in a short time.In tunnel double-lining concrete construction, steam curing effect is better than
Watering maintenance, spraying curing agent, are restricted by section configuration, construction environment, are more difficult to realize during practice of construction.
Previous tunnel construction technology is original, and construction cycle period is long, is in no hurry to form removal, template after lining concrete cast
Leakproofness blocked concrete moisture escape paths, (be known as curing in the mold effect), engineering practice verification for many years, even if not
Other maintenance measures are taken, the final strength of concrete will not be caused to significantly affect, tunnel double-lining concrete is formed and does not support
The inertial thinking of shield.
Due to the fast development of tunnel double-lining construction technology, the application of lining trolley+pumped concrete earth process, mechanization journey
Degree is substantially improved, and lining construction cycle period shortens, and two lining concrete curing in the mold effects is caused substantially to weaken.While with
The development of high-speed railway, more stringent requirements are proposed for the quality of the application of high performance concrete to concrete.In addition construction personnel
Inertial thinking, ignore the importance of two lining concrete curings, existing concrete curing caused to be taken effective measures, lining cutting coagulation
The inferior strong, face checking of soil, decortication chip off-falling and other issues take place frequently.
