Description
Technical field
The present invention relates to a kind of concrete curing device, the particularly curing means for tunnel double-lining concrete.
Background technology
, it is necessary to carry out secondary lining to tunnel surrounding again after supporting in the early stage in the work progress in tunnel.It is secondary
Liner structure is not only a kind of structural measure as safety stock, but also to ensure that tunnel prevents from oozing in use
Water, ensure surface with respect to finishing, smooth, attractive in appearance, this just need requirement tunnel double-lining concrete have enough intensity with it is durable
Property.And it is many for the influence factor of concrete strength and durability, wherein during concrete curing, temperature is with humidity to mixed
Solidifying native intensity and durability influence maximum.During China's constructing tunnel, concrete curing is typically using the side directly conserved
Formula, if maintenance not in time, it is insufficient, can not just ensure concrete surface suitable temperature and humidity, cause concrete hydrating
Thermal response can not be carried out, and its direct result is that tunnel concrete has intensity deficiency, even concrete cracking phenomenon.
At present, most of tunnel maintenance uses the maintenance measure of man-hour manually hand-held water pistol water spray, its maintenance effect and worker
Subjectivity it is directly related, often cause maintenance not in time with conserve phenomenon not in place.For this problem, certain enterprise develops
Spray chassis, on the top of chassis and side installation high-pressure nozzle, bottom is equipped with storage tank and pressure pump, controls during operation
Curing water is transported to shower nozzle by pressure pump from storage tank through water pipe, to realize that the sprinkling to concrete conserves.The above two
The actual effect of kind mode is simultaneously bad, on the one hand can cause major injury to concrete surface using high-pressure nozzle；On the other hand
The water to gush out can flow to ground along vault and side wall, and site work environment is impacted, and can cause water waste.
