Description
Technical Field
The utility model relates to a pier stud sprays curing means, concretely relates to high pier stud slip form concrete intelligence of bridge sprays curing means.
Background
The construction of sliding formwork is one construction process for in-situ concrete engineering. When the slip form is constructed, the templates are assembled at one time, and an operation platform for constructors is arranged on the templates. And simultaneously sliding and lifting and continuous operation are carried out from bottom to top along the cast-in-place concrete surface while pouring concrete. Compared with the conventional construction method, the construction process has the advantages of high construction speed, good overall structure performance, high degree of mechanization, capability of saving work materials required by formwork support and scaffold erection, capability of conveniently detaching the formwork, flexible assembly, reusability and the like. The slip form is combined with other construction processes (such as prefabrication assembly, masonry or other formwork supporting methods and the like), so that conditions can be created for simplifying the construction process, and comprehensive economic benefits can be better obtained.
After concrete is poured, if the concrete is maintained in hot weather and air drying in time, water in the concrete can evaporate too fast to form a dehydration phenomenon, so that cement particles which form gel cannot be fully hydrated, cannot be converted into stable crystals, and lack of sufficient cohesive force, and thus, flaky or powdery falling can occur on the surface of the concrete. Further, when the concrete does not have sufficient strength, the moisture evaporates early, and large shrinkage deformation occurs, and shrinkage cracking occurs. Therefore, the curing of the concrete in the initial stage after the concrete is poured is very important, the curing should be performed immediately after the concrete is finally set, and the curing should be performed immediately after the pouring of the hard concrete is completed.
Concrete curing is the artificial creation of certain humidity and temperature conditions that allow the as-cast concrete to harden normally or accelerate its hardening and strength growth. The ability of concrete to gradually harden and develop strength is a result of the hydration of cement, which requires certain temperature and humidity conditions. If the surrounding environment does not have the condition, the concrete needs to be cured manually. The concrete curing method comprises the following steps: firstly, natural maintenance: and (5) separately spraying water for maintenance and spraying a plastic film for maintenance. The former is covered with concrete with a straw mat or the like, and is kept wet by spraying water frequently. The curing time depends on the cement variety, such as ordinary portland cement concrete not less than 7 days and nights. The latter is suitable for tall structures and large-area concrete structures which are difficult to be maintained by sprinkling water, etc. the perchloro-vinyl resin plastic solution is sprayed on the surface of the concrete by a spray gun, a layer of film is formed on the surface of the concrete after the solution is volatilized, the concrete is isolated from the air, the evaporation of water in the concrete is prevented, the normal operation of the hydration of the cement is ensured, and the film can age and fall off automatically after the maintenance is finished. Secondly, steam curing: the concrete member is placed in a curing chamber filled with saturated steam or a mixture of steam and air to accelerate the hardening of the concrete in a high temperature and humidity environment. The curing effect is related to a steam curing system, and comprises the following steps: standing time before steam curing, heating and cooling speed, curing temperature, constant-temperature curing time, relative humidity and the like. The steam curing chamber has a pit type, a vertical kiln type and a tunnel kiln type.
The highway construction in China is in the high-speed development period, the bridge engineering is an important component of the highway construction in China, and the bridge high pier concrete construction and maintenance process is a key process for ensuring the quality of pier column concrete. Due to the high-altitude operation, the problems that the pier column is not maintained in place and the early strength of concrete is low easily caused by factors such as inconvenient traction of maintenance water, large transverse wind and easy scattering of sprayed maintenance water, management negligence of managers, low quality of operators and the like.
