Abstract
The invention relates to an energy-saving concrete maintenance method by temperature-controlled automatic water supply and hot water circulation, which comprises the following steps: adopting a combined maintenance method of internal radiation and external storage, namely, arranging a circulated cooling water pipe in a bearing platform, and cooling circulated flowing water during concrete construction and maintenance to accelerate radiation of heat inside the large-sized concrete of the bearing platform; after the concrete is poured and then initially set, covering a layer of film and two layers of gunny bags to carry out heat and moisture preservation and maintenance; during the heat and moisture preservation and the maintenance of the bearing platform, according to the temperature of a site environment, monitoring temperature and temperature difference of inlet water and outlet water of the cooling water pipe by an automatic temperature measuring control system, automatically reclaiming hot water in the cooling water pipe, recharging a water pool by part of the hot water for cyclic utilization, and controlling the difference value of the inlet water temperature of the cooling water pipe and the highest temperature of the concrete to be lower than 25 DEG C; and recharging the surface of the bearing platform by the other part of the hot water for heat preservation and maintenance. The method adopts the combined maintenance method of the internal radiation and the external storage, fully meets civilized construction requirements of environmental protection, energy conservation, and circulation, and can ensure the maintenance quality of the bearing platform of the large-sized concrete.
Description
Technical field
The present invention and a kind of building concrete construction and maintenance method, especially a kind of employing temperature-controlled automatic water-compensating and cyclic hot-water method for maintaining concrete.
Background technology
Concrete is a hydraulic material, and concrete will carry out hydration in the setting and harden process, do not keep the skin wet, and just can not proceed hydration.In the concrete strength rise period, be the moisture loss of avoiding surface evaporation and other reasons to cause, the concrete hydrating effect is carried out fully, guarantee technical indicators such as concrete intensity, durability, produce the crack for preventing owing to dry simultaneously, must carry out maintenance it.
Conventional maintenance method has three kinds: 1, directly spread water curing at concrete bearing platform or post table after the form removal; 2, spread water at concrete bearing platform or post table after the form removal and wrap up the gunnysack maintenance then; 3, spread water at concrete bearing platform or post table after the form removal and wrap up the plastic sheeting maintenance then.
But above-mentioned three kinds of methods also can't satisfy the distributing of internal heat of large-volume concrete bearing platform, directly have influence on the maintenance quality of large-volume concrete bearing platform.
Summary of the invention
The present invention is the technical problem that will solve the large-volume concrete bearing platform maintenance, and provide a kind of energy-saving type temperature-controlled automatic water-compensating and cyclic hot-water method for maintaining concrete, loose in this method adopts and holds the comprehensive maintenance method outward, demonstrate fully green, civilized construction energy-conservation, circulation requires and guarantee the large-volume concrete bearing platform maintenance quality.
The technical scheme that the present invention solves the problems of the technologies described above is: a kind of energy-saving type temperature-controlled automatic water-compensating and cyclic hot-water method for maintaining concrete, hold the comprehensive maintenance method outside loosing in adopting, and its concrete steps are:
1. circulating cooling water pipe is set in cushion cap, and the water flowing that circulates in concrete construction and between curing period cooling is to accelerate distributing of platform big volume inside concrete heat;
2. after concreting is finished, treat that concrete initial set finishes after, cover promptly that two layers of gunnysack of thin film are incubated, moisture-keeping maintaining;
3. in cushion cap heat and moisture preserving maintenance processes, according to the site environment temperature, by the automatic temperature measurement control system, the monitoring cooling water pipe Inlet and outlet water temperature and the temperature difference, automatically reclaim the hot water in the cooling water pipe, a part is recharged in the pond, and is recycling, and control cooling water pipe inflow temperature and concrete maximum temperature difference are less than 25 ℃; Another part recharges the cushion cap surface and carries out insulated curing.
In the above-mentioned steps, micro computer monitoring concrete internal temperature situation is adopted in the cushion cap concrete curing, according to the concrete internal temperature of actual measurement, adjusts surperficial tectal thickness, concrete internal temperature is controlled in 25 ℃ in the surface temperature difference, when the temperature difference is not more than 20 ℃, cancels maintenance.
In above-mentioned second step, overlap joint was not less than 10cm when film covered, and covered with the gunnysack overlap joint of riding.
The invention has the beneficial effects as follows: loose in this method adopts and holds the comprehensive maintenance method outward, demonstrate fully green, civilized construction energy-conservation, circulation requires and can guarantee the large-volume concrete bearing platform maintenance quality.
