End is connected to the water inlet end of external thermal insulation pipe 10；The discharge ends of external thermal insulation pipe 10 are connected to the water inlet end of return water main pipe 11；Return water is dry
The discharge ends of pipe 11 are communicated to the water inlet end of water circulating pump 1, and water circulation path is consequently formed.
It further include temperature sensitive probe 12, display and controller；
Each to bury multiple temperature sensitive probes 12 in the inside and outer surface of mass concrete 6, each temperature sensitive probe 12 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,
Reserve multiple pre- holes 5 using the concrete of final set, the inside in each pre- hole is cavity structure, the front end in each pre- hole and
Rear end respectively connects front end water supply hose and rear end water supply hose；After front end water supply hose is pooled to front end water supply branch pipe, then pass through
Front end is connected for one end of water conduit tube and water circulating pump；After rear end water supply hose is pooled to rear end water supply branch pipe, then pass through rear end
One end of external thermal insulation pipe is connected to for water conduit tube, the other end of external thermal insulation pipe is connected by the other end of return water main pipe and water circulating pump
It connects.
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 inside pre- hole 5 by each front end water supply branch pipe 3, so that water be made directly to contact with mass concrete, is realized
Direct heat exchange, since water is directly contacted with concrete in the application, it is a kind of direct cooling mode；Water pass through with it is big
After volume concrete heat exchange, temperature rises, and the water after heating is pooled to rear end water supply branch pipe by rear end water supply hose, then flows
Enter rear end for water conduit tube, be then flowed into external thermal insulation pipe 10, outwardly function of environment heat emission, heat dissipation are laggard while to concrete heat-insulating
Enter return water main pipe 11, completes cyclic process.As it can be seen that recirculated water absorbs the heat of hydration of concrete, reaches and reduce temperature inside and outside concrete
The purpose for spending difference, prevents mass concrete from cracking, and the required heat of heat preservation is provided outside concrete, reduces winter
Construction site is the heat of concrete heat-insulating.
In the application, a hole 5 is one group of heat exchanger in advance, and construction water is by the way that it is big to reach reduction after opening 5 heat exchange of hole in advance
The purpose of volume 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 12 and signal wire are embedded in concrete blinding by design requirement, warming is visited
First 12 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 12 is connected to display and observes each warming
The concrete temperature that probe 12 transmits, while water circulating pump 1, front end are connected for water conduit tube 2, front end water supply branch pipe 3, front end water supply
Hose 4, rear end water supply hose 7, rear end water supply branch pipe 8, rear end are for water conduit tube 9, external thermal insulation pipe 10 and return water main pipe 11；Wherein,
Front end water supply hose 4 and rear end water supply hose 7 only have one small section of both ends for being inserted into pre- hole, and hole main body is interior in advance and is not present
Water supply hose.Then, water circulating pump 1 is connected to cool down to inside concrete, if the temperature difference inside and outside concrete is greater than 25 degree,
Need to increase the flow of water circulating pump 1, temperature difference of the fast cooling inside and outside concrete splashs coagulation less than 25 degree
Native external temperature, if 5 degree of external temperature <, Ying Kaiqi water circulating pump, cool down terminated until the concrete curing phase in aforementioned manners,
It also needs thoroughly to prevent mass concrete from opening in this way in conjunction with the concrete curing method of other coverings, moisturizing, heat preservation simultaneously
It splits, 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 5 in advance, and construction water directly contacts with concrete cooling pre-
Concrete around hole 5, when can be avoided indirect cooling, in advance in hole 5 moisturizing not in time, partial interior hydration heat of concrete
Fail to discharge completely, heat exchange efficiency is done, and concrete integrally cools under hygrometric state, directly cooling more direct good cooling results.
It is provided by the utility model to be had the advantage that based on the direct self-insulation system of severe cold area concreting in cold weather
(1) water supply hose of the application can extract recycling out, and water supply hose only has a very short segment pipe to exist
In advance in hole, lot of materials and water resource are saved.And the construction water after heating up outside concrete directly to keeping the temperature, it is real
The abundant effective and reasonable utilization to energy is showed.
(2) moisturizing is abundant in hole in advance, and the concrete around the directly cooling pre- hole of construction water can be avoided indirectly cold
When but, moisturizing not in time, causes pre- hole cracking or abrasion, directly cooling more indirect good cooling results in hole in advance.
(3) recirculated water water temperature after heat exchange increases, and to extraneous function of environment heat emission in outer insulating tube, that is, eliminates 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.
