Abstract
The invention discloses a method for constructing novel winter concrete health blankets. The concrete health blankets can be spliced with one another to adapt different concrete curing area, and can also be applied to concrete curing of different shapes. The concrete health blankets can be used for areas of different power grids; by adopting a 36V working voltage, the method is safe and reliable; the health blankets are low in cost, so the construction cost input can be reduced; meanwhile, the health blankets can be reused, so that the utilization rate is improved; the health blankets can be spliced with one another, so the health blankets facilitate field construction; and the curing temperature is stable and controllable, and the concrete curing quality can be improved.
Description
Technical field
The present invention relates to a kind of method of cold weather concrete health blanket construction.
Background technology
In cold area and winter construction, the method for various concrete heat-insulatings and maintenance is each most difference also.Commonly used at present is to adopt the method for setting up interim frame and lighting stove, and perhaps at the concrete surface covering insulation material, carries out self supplying warm maintenance through the inside concrete heat of hydration.Mainly there is following problem in this traditional insulation and the maintenance construction:
1, set up interim frame and light stove and carry out the maintenance construction cost and have high input, it is loaded down with trivial details to construct simultaneously, and is prone to cause fire;
2, concrete surface covering insulation material maintenance quality is lower, and the surface is prone to the crack, and maintenance effect is unreliable.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, providing a kind of and can improve and improve the concrete curing method for quality.
Technical solution problem of the present invention provides following scheme:
A kind of method of cold weather concrete health blanket construction is characterized in that:
(1) at first; The health blanket of completion of processing is covered on the concrete surface that needs maintenance; For the large area concrete health, can adjust the health area through the mutual connection of the terminal of health blanket, perhaps for the health of bridge column; Can connect through terminal between polylith health blanket, with the whole parcel of column;
(2) secondly, the output voltage of adjusting adjustable isolating transformer 72V is 36V, and energized provides heat through the heating of heating galvanized wire for concrete curing, and geotextiles can realize heat insulation function simultaneously;
(3) last, temperature controller is adjusted the concrete curing temperature automatically, realizes the purpose of concrete heat-insulating maintenance.
Said health blanket comprises constantan wire, heating galvanized wire, geotextiles; Said heating galvanized wire is fixed on up and down between the two-layer geotextiles according to uniform spacing; The rear and front end of said heating galvanized wire links to each other with constantan wire; Said constantan wire connects the copper conductor of right ends respectively, and the rear and front end Tou Chu of said copper conductor is provided with terminal, is serially connected with temperature controller and adjustable isolating transformer on the said copper conductor.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, the present invention uses 36V low pressure, and is safe and reliable;
2, the present invention adopts health blanket cost low, can reuse simultaneously, increases operation rate;
But execute-in-place is convenient in 2, the present invention's assembly unit each other, saves manpower, increases the benefit;
3, curing temperature of the present invention is controlled and stable, can improve maintenance quality.

The specific embodiment
Referring to accompanying drawing, a kind of method of cold weather concrete health blanket construction is characterized in that:
(1) at first; The health blanket of completion of processing is covered on the concrete surface that needs maintenance; For the large area concrete health, can adjust the health area through the mutual connection of the terminal of health blanket, perhaps for the health of bridge column; Can connect through terminal between polylith health blanket, with the whole parcel of column;
(2) secondly, the output voltage of adjusting adjustable isolating transformer 72V is 36V, and energized provides heat through the heating of heating galvanized wire for concrete curing, and geotextiles can realize heat insulation function simultaneously;
(3) last, temperature controller is adjusted the concrete curing temperature automatically, realizes the purpose of concrete heat-insulating maintenance.
Said health blanket comprises constantan wire, heating galvanized wire, geotextiles; Said heating galvanized wire is fixed on up and down between the two-layer geotextiles according to uniform spacing; The rear and front end of said heating galvanized wire links to each other with constantan wire; Said constantan wire connects the copper conductor of right ends respectively, and the rear and front end Tou Chu of said copper conductor is provided with terminal, is serially connected with temperature controller and adjustable isolating transformer on the said copper conductor.
