Description
Technical Field
The invention relates to the technical field of concrete pole production, in particular to a steam curing method of a concrete pole.
Background
The concrete pole is commonly called a telegraph pole and can also be called a concrete pole, and the concrete pole is formed by processing concrete, reinforcing steel bars and steel wires through various procedures. The concrete pole is used for erecting a power cable to facilitate power or telecommunication to keep away from a transmission structure, and is mainly used for power grid and communication construction.
The production process of the concrete pole roughly comprises the steps of framework manufacturing, concrete stirring, concrete pumping, centrifugal forming, steam curing and form stripping and demoulding.
In the middle of this step to steam curing, use the purlin car to transport centrifugal molding's pole to evaporate and keep in the cellar for storing things pond, steam lets in to the cellar for storing things pond through the pipeline in, and the source of steam generally is provided by the boiler, places the concrete pole that evaporates and keeps in the cellar for storing things pond this moment and can pass through following four stages.
A static stop stage: the static stop stage is also called a pre-curing period, a pre-setting period or a standing period, and is a period of standing time in the atmospheric environment after the cement electric pole is formed and before steam curing begins. The stage mainly ensures that cement in the concrete is hydrated to a certain degree and has certain structural strength, so that the structure is prevented from being damaged by volume expansion of the concrete in the temperature rise period.
A temperature rising stage: if the early pre-curing time of the electric pole is longer, the initial structural strength is higher, and the heating rate can be correspondingly improved; otherwise, the temperature is slowly increased. At this stage the concrete strength is increased and it is necessary to ensure a sufficient thermostatting time and corresponding thermostatting temperature, otherwise the design strength is not reached.
And (3) a constant temperature stage: the main control parameter of the thermostatic stage is the thermostatic time of the thermostatic temperature. For cement and concrete products, the higher the temperature and the longer the curing time in the thermostatic stage, the higher the ultimate strength of the pole. However, the excessively high constant temperature and the long heat curing time cause the loss of the later strength of the electric pole or the damage of other characteristics, so the selection of the proper constant temperature is very important for the steam curing process.
And (3) cooling: in the cooling stage, steam is slowly stopped, the temperature is uniformly cooled, and the humidity is kept, wherein the time is determined according to the production cycle, and the longer the time in the cooling stage is, the better the time is.
A plurality of concrete supports used for supporting the electric pole can be usually poured at the bottom of the cellar pool, a steam pipeline is arranged between the supports and the steam pipeline, the steam pipeline is installed at the bottom of the cellar pool, and steam is evaporated and cured in the cellar pool. When the electric pole is in steam curing, in the constant temperature stage, the temperature is 85 ℃ at the constant temperature, and the electric pole can be dismantled only by keeping the constant temperature for 3-3.5 hours. In some enterprises with limited factory buildings, the number of the used pit pools is limited, so that the yield is low, and meanwhile, when the steam curing pool is used for steam curing the electric pole, part of residual heat is dissipated from the surface of the cover body of the pit pool, so that heat loss is caused; secondly, steam is used during steam curing, so that liquefaction is generated inside the pit, water is remained in the pit for a long time and is mixed with concrete dropped on the template, and the bottom of the pit is difficult to clean.
The publication No. CN207736495U discloses a concrete cement electric pole steam-curing pool, a pool body is close to the bottom of a pool cavity and is provided with a water outlet communicated with the pool cavity, the pool body is further provided with a gas outlet communicated with a ventilation cavity, the bottom of the pool cavity is detachably provided with a bedding layer, and the bedding layer is provided with a plurality of water outlet holes.
Through setting up the delivery port in the above-mentioned scheme, the water after the water vapor liquefaction of bottom of pool chamber is easily taken the concrete and is flowed through the outlet pipe from the delivery port of bottom of pool chamber, is equipped with sedimentation tank and filter on the outlet pipe for liquid is filtered, prevents that solid particle in the liquid from blockking up the outlet pipe and causing the pollution to the external world. However, when the electric pole is steamed, in some enterprises with limited plant areas, the number of the cellars for steaming is not large, the temperature is 85 ℃ at constant temperature, and the electric pole can be dismantled after the constant temperature is maintained for 3-3.5 hours.
