Abstract
The invention provides a method and device for maintaining concrete by local heating. The technology comprises concrete covered by thin films and a heating blanket covered by a blanket. Before concrete pouring, a cooling water pipe and a thermometer are embedded inside the concrete structure; after concrete pouring is finished, the concrete is covered by thin film for moisture and heat preservation; at the same time, circulated cooling water is used for uniformly cooling the inner of the concrete and the internal and external temperature of the concrete is monitored and recorded; after the concrete is solidified at early stage, the heating blanket is laid on the thin film and performs local heating on the concrete after connecting to power supply; the output power of the heating blanket is properly regulated according to actually measured temperature of the concrete in the construction site; blanket is added on the heating blanket according to real time weather conditions to perform insulation maintenance until the concrete maintenance is completed.
Description
Technical field
The present invention relates to a kind of concrete curing measure, concretely relate to a kind of concrete local heating curing method and device.
Background technology
During concrete engineering construction, maintenance is most important.Winter construction of concrete, because of cold weather, especially freezing weather, have a strong impact on the strength development of newly-laid concrete, cause and also be difficult under later concrete normal temperature maintenance recover to original design intensity, the most often taking measures to prevent concrete from enduring cold, allow concrete strength can rise to concrete early freezc under normal temperature conditions and allow more than critical intensity, concrete may ultimately reach design strength and do not loses.At present, concrete curing frequently with two ways, i.e. natural curing and external heat maintenance.Cast-in-place concrete the most generally uses natural curing, commonly uses external heat maintenance during winter construction.Concrete external heat, mainly by heating concrete component surrounding air, transfers heat to concrete, to reach maintenance effect.Though the method heating curing is effective, almost can reach laboratory mark and support level, but owing to its heating process energy loss is too big, not be suitable for big member concrete heating curing, be unfavorable for that scene is promoted the use of.
Summary of the invention
For prior art weak point, it is an object of the invention to provide a kind of concrete local heating curing method and device.The method and device are on the basis of thin film covering curing, and with electric energy for for heat energy, xoncrete structure being carried out local by electric blanket and heat, woollen blanket is covered on electric blanket, slows down concrete surface heat and scatters and disappears.The method and device use in winter construction of concrete maintenance processes, shorten its drying time, are substantially shorter the concrete construction cycle, bring economic benefit for engineering.Meanwhile, cooling, external thermal insulation measure in concrete, it is to avoid excessive internal-external temperature difference causes distress in concrete, it is ensured that winter construction quality.
For achieving the above object, the present invention solves its technical problem and is adopted the technical scheme that: a kind of concrete local heating curing method, its specifically comprises the processes of: before concreting, inside its xoncrete structure, bury cooling water pipe and thermometer underground；After concreting completes, cover film moisturizing in its surface, insulation, meanwhile, utilize recirculated cooling water for inside concrete uniform decrease in temperature, and monitor and record concrete internal and external temperature；After concrete initial set, thin film is laid electric blanket, connection power supply, concrete carries out local heat, and according to the observed temperature of concrete on construction site, suitably adjust the output of electric blanket, and according to real-time weather conditions, electric blanket is set up woollen blanket cover, carry out insulated curing, until concrete curing completes.
Further, before described electric blanket energising, carry out security inspection, and during heating curing, according to the climate condition of job site, the thick big degree of concrete component and the observed temperature of concrete, heighten or turn down the output of electric blanket, it is ensured that temperature difference between inside and outside concrete controls in proper range, and do not cause energy waste.
Based on aforesaid method, the present invention have also been devised a kind of concrete local heating curing device, including being coated with the concrete of thin film and being coated with the electric blanket of woollen blanket.Described electric blanket has height gear handoff functionality, cover film on described concrete, it is for conventional concrete curing measure, described electric blanket upper cover has woollen blanket, heat is prevented to scatter and disappear, local heating concrete is effectively incubated, in described concrete, cooling water pipe is buried in layering underground, pass through circulating water, uniformly reduce concrete internal temperature, described concrete centre and edge bury thermometer T1 and thermometer T2 respectively underground, in order to monitor concrete observed temperature, rationally to heighten or turning down electric blanket output, ensure that temperature difference between inside and outside concrete controls in proper range, and do not cause energy waste.
As preferably, described concrete covers thin film, concrete is had moisturizing, insulated curing effect.
As preferably, described cooling water pipe becomes S-shaped, and in described concrete, layering is laid, and after concreting completes, utilizes cooling water pipe circulating water, for inside concrete uniform decrease in temperature.
The method and device of the present invention uses when concrete curing, provide the benefit that: after concrete construction, utilize cooling water pipe circulating water, for inside concrete uniform decrease in temperature, in conjunction with having insulation, the thin film of heating function, woollen blanket and electric blanket etc., reduce concrete surface heat to scatter and disappear, it is to avoid excessive internal-external temperature difference causes distress in concrete, it is ensured that winter construction quality.It addition, to concrete local heating and thermal insulation, shorten its drying time, be substantially shorter the concrete construction cycle, bring economic benefit for engineering.Meanwhile, the method and device are simple to operate, low energy consumption, and beneficially scene is promoted the use of.
