The water inlet end of main pipe 10 is connected to；The discharge ends of return water main pipe 10 are communicated to the water inlet end of water circulating pump 1, and it is logical that water circulation is consequently formed
Road.
It further include temperature sensitive probe 11, display and controller；
Each to bury multiple temperature sensitive probes 11 in the inside and outer surface of mass concrete 6, each temperature sensitive probe 11 is furnished with
Signal wire, the signal wire are all connected to the input terminal of controller；The output end of controller is connect with display.
Its principle are as follows:
The utility model utilizes the pipeline core-drawing pore-creating principle in the prestressed concrete post stretching of building engineering construction field,
Multiple pre- holes 5 are reserved using the concrete of final set, the inside in each pre- hole is cavity structure, the inside quilt in each pre- hole
A piece water supply hose 4 of installation completely；After the water outlet of water circulating pump passes sequentially through front end for water conduit tube 2 and front end water supply branch pipe 3, stream
Enter water supply hose 4, water change exchanging by water supply hose 4 with the concrete around pre- hole, and the water after heating passes through rear end
After water supply branch pipe 7 and rear end are for water conduit tube 8, external thermal insulation pipe 9 is flowed into, water pump is then flowed back to by return water main pipe 10 again, it is thus complete
At a waterway circulating.
Therefore, after recirculated water is recycled by water circulating pump 1, by front end for water conduit tube 2, front end water supply branch pipe 3 is flowed into, then
It is flowed into water supply hose 4 by each front end water supply branch pipe 3, to pass water through around water supply hose and in advance hole substantially
Product concrete indirect heat exchange, due to water and concrete in the application and is not directly contacted with, confession is separated between water and concrete
Therefore water hose is a kind of indirect type of cooling；Water supply hose is one group of heat exchanger, and recirculated water is handed over by water supply hose heat
After changing, achieve the purpose that reduce mass concrete internal temperature.After exchanging heat with mass concrete, temperature rises water,
Water after heating is pooled to rear end water supply branch pipe, then flows into rear end for water conduit tube, external thermal insulation pipe 9 is then flowed into, to concrete
Outwardly function of environment heat emission while heat preservation enters return water main pipe 10 after heat dissipation, complete cyclic process.It is mixed as it can be seen that recirculated water absorbs
The heat of hydration for coagulating soil achievees the purpose that reduce concrete inside and outside temperature difference, prevents mass concrete from cracking, and in concrete
Heat needed for outside provides heat preservation reduces the heat that winter construction scene is concrete heat-insulating.
In the application, water supply hose 4 is one group of heat exchanger, and construction water is opened around hole by water supply hose 4 and in advance
After concrete carries out heat exchange, achieve the purpose that reduce mass concrete internal temperature.
Temperature sensitive probe is embedded in concrete and equipped with signal wire, and signal wire is connected with display, can measure and show
The temperature of concrete.
Relative to the method for the cooling mass concrete of recirculated cooling water, the water supply hose of the application can extract repetition benefit out
With saving lot of materials and water resource, and the recirculated water after heating up is used for concrete heat-insulating.
Need to illustrate: water supply hose can be the tubing of steel pipe, plastic tube or other materials, have no effect on the essence of this patent
Property content；
When Specific construction, first temperature sensitive probe 11 and signal wire are embedded in concrete blinding by design requirement, warming is visited
First 11 is generally embedded at concrete core position and external packet, in order to measure the temperature difference inside and outside concrete；It is poured coagulation
Soil simultaneously constantly rotates drawing core pipe, until concrete final set, concrete no longer slump, drawing core pipe is extracted out, in this way in concrete
Inside it is formed the pre- hole 5 by design requirement；The signal wire of temperature sensitive probe 11 is connected to display and observes each warming
The concrete temperature that probe 11 transmits, while water circulating pump 1, front end are connected for water conduit tube 2, front end water supply branch pipe 3, water supply hose
4, rear end water supply branch pipe 7, rear end are for water conduit tube 8, external thermal insulation pipe 9 and return water main pipe 10；Wherein, water supply hose is completely inserted into pre-
It opens in hole, the water supply hose of equal length is inserted into pre- hole.Then, water circulating pump 1 is connected to cool down to inside concrete, if
Temperature difference inside and outside concrete is greater than 25 degree, then needs to increase the flow of water circulating pump 1, and fast cooling is until inside and outside concrete
Temperature difference splashs concrete external temperature less than 25 degree, if 5 degree of external temperature <, Ying Kaiqi water circulating pump, use is above-mentioned
Method cooling terminates until the concrete curing phase, while also needing to combine the concrete curing method of other coverings, moisturizing, heat preservation,
Thoroughly it could prevent mass concrete from cracking in this way, finally when concrete curing is completed, with pre- hole 5 of cement slurry closure.
Need to illustrate: such mode is not required to the deliberately moisturizing in hole in advance, and the coagulation around hole is opened in cooling to recirculated water in advance indirectly
Soil, when can be avoided direct cooling, water velocity is too fast in hole in advance, and pre- hole is caused to wash away, to cause pre- hole cracking
Or abrasion, indirect cooling more direct good cooling results.
It is provided by the utility model to be had the advantage that based on the indirect self-insulation system of severe cold area concreting in cold weather
(1) water supply hose of the application can extract recycling out, save lot of materials.And the water after heating up is directly right
It is kept the temperature outside concrete, realizes the abundant effective and reasonable utilization to energy.
(2) concrete around hole is opened in cooling to recirculated water in advance indirectly, when can be avoided direct cooling, opens water flow velocity in hole in advance
It spends fastly, pre- hole is caused to wash away, so that pre- hole cracking or abrasion are caused, indirect cooling more direct good cooling results.
(3) recirculated water water temperature after heat exchange increases, and to extraneous function of environment heat emission in outer insulating tube, has both eliminated substantially
Product inside concrete heat, while again to winter construction when concrete keep the temperature, economical environment-protective.In addition, due to simultaneously
Therefore carry out warming temperature to mass concrete inside, can effectively reduce to heat preservation operation is carried out outside mass concrete
Temperature difference between inside and outside concrete improves concrete curing quality to prevent concrete cracking and frostbite.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching should also regard the protection scope of the utility model.
