Abstract
The utility model relates to a heat pipe maintenance device, which is casted by mass concrete, wherein a plurality of cannulas whose lower end surfaces are closed and are inserted in concrete which is compactly casted, a gravity heat pipe is arranged in each cannula, the upper portion of the heat pipe is arranged on the upper portion of concrete, the periphery of the heat pipe on the upper portion is provided with a cooling cannula, the cooling cannulas are communicated through a connecting pipe, and cooled medium water flows in the cannulas. The heat pipe maintenance device can rapidly emanate a great amount of hydration heat generated in concrete to atmosphere, thereby reducing cracks, and improving the poured quality of concrete.
Description
Technical field
The utility model relates to the casting of concrete in mass curing means, particularly a kind of concrete hot pipe curing means that the inside concrete heat of hydration can be distributed fast.
Background technology
In casting of concrete in mass processes such as heavy construction such as dam, speedway, airport, the control concrete internal temperature is a crucial job.It directly has influence on workmanship, construction speed and the investment of large-sized concrete structure.Can emit a large amount of heats of hydration in hardening period after the concreting, internal temperature constantly raises.Along with weakening gradually and the concrete heat radiation of environment towards periphery of hydration, temperature descends and tends towards stability.In such temperature changing process, will have a strong impact on the globality and the durability of structure because of the crack of temperature difference generation.So be reduced in the maximum temperature of inside concrete in the maintenance processes and reduce the poor of maximum temperature and equilibrium temperature, to the intensity that guarantees concrete construction, prevent that from there is the ten minutes significant meaning in the crack.
At present, the maximum temperature a kind of feasible measure commonly used that is reduced in inside concrete in the maintenance processes is exactly embedding water pipe, and water flowing is cooled off.Its major defect has two: the one, and the water flowing time is longer, and some reaches some months, consumes great amount of manpower and material resources, the energy and water source; The 2nd, in the water pipe of being buried underground, constantly rise along the flow direction water temperature of water, its cooling effect constantly descends, and promptly the thermal field is inhomogeneous, and instantaneous maximum temperature and maximum temperature difference are all bigger in cooling procedure.For making them reach the scope of permission, must increase cooling water flow, thereby also increase the input of water source and low-temperature receiver.
Summary of the invention
The purpose of this utility model provides a kind of simple, concrete hot pipe curing means faster of lowering the temperature, thereby guarantees the pouring quality of concrete in mass.
The purpose of this utility model is realized by following scheme:
A kind of concrete hot pipe curing means, it is the sleeve pipe 5 that is inserted with many lower surface sealings in building closely knit concrete 6, be provided with gravity assisted heat pipe 4 in the every sleeve pipe 5, the top of heat pipe 4 is in the top of concrete 6, the periphery of top heat pipe 4 is provided with cooling collar 2, each cooling collar 2 is connected by tube connector 3, and cooling medium water 1 is flowing in the pipe.
The above-mentioned many sleeve pipes 5 that are plugged in the concrete 6 are vertically to plant from top to bottom, and disposed at equal distance between each sleeve pipe 5.
Concrete hot pipe curing means of the present utility model has overcome at present in the concrete in mass building embedding water pipe water flowing and has cooled off long, the shortcomings such as water temperature is inhomogeneous, waste of manpower, material resources, the energy, water source of water flowing time of appearance.Can make in the concrete because the temperature rise that hydration heat of cement causes reduces temperature gradient decline; Reduced the time of equilibrium temperature, thermal stress and strain facies should be reduced; Thereby reduced the generation of distress in concrete, improved the quality of concreting, it is effective curing means of casting of concrete in mass.
Description of drawings
Fig. 1 is a plane structure schematic diagram of the present utility model.
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1.
The specific embodiment
Above accompanying drawing is disclosed to be the structure of an embodiment of the present utility model.
Consult Fig. 1, Fig. 2,1 is cooling medium water among the figure; 2 is cooling collar, adopts the common steel tube manufacturing, on sale on the market; 3 is tube connector, and the PVC plastic pipe is on sale on the market; 4 is gravity assisted heat pipe, adopts the common steel tube manufacturing, sealed at both ends, and inside is for negative pressure and fill working media, and its capacity of heat transmission surpasses existing known metal, and matured product is on sale on the market; 5 is concrete sleeve, adopts the common steel tube manufacturing, on sale on the market; 6 is the concrete of building.
The fringe conditions of building according to concrete 6 is determined following parameter as the pouring construction scheme of weather temperature decision concrete 6: concrete 6 to build thickness be H=1.5～2.0 meter, when concrete 6 build closely knit after, in initial setting time, be arranged vertically concrete sleeve 5 with equidistant (L=1.0～1.5 meter).Concrete sleeve 5 length are that concrete 6 is built thickness.In 12 hours, gravity assisted heat pipe 4 is inserted in the concrete sleeve 5.The internal diameter value D=22 millimeter of general concrete sleeve 5, the external diameter value of force of gravity heat pipe 4 (d=20 millimeter) is big 2 millimeters.
Be the embodiment of certain building site concrete 6 pouring construction scheme below: 20 ℃ of weather temperature, concrete 6 are built 1.5 meters of thickness.Build closely knit after, in 1 hour, use oscillator (construction tool immediately, concreting personnel indispensability, the market is on sale) concrete sleeve 5 is vertically planted in the concrete 6, concrete sleeve 5 is disposed at equal distance each other, and 1 meter of spacing is on one side can arrange concrete sleeve 5, on one side gravity assisted heat pipe 4 is inserted in the concrete sleeve 5, purpose is the concrete 6 inner heats that produce to be brought in the atmosphere to go fast.
According to different weather temperature, change the spacing of concrete sleeve 5, the concrete 6 inner heats that produce are dispersed in the atmosphere fast go, thereby can improve the quality of concreting.
If unspecified content is arranged, should be the known technology that maybe should know of professional and technical personnel in more than narrating, do not repeat them here.
