Solidifying soil cracking.
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 6 are reserved using the concrete of final set, air supply hose 5 is protruded into concrete and is opened in hole 6 in advance, also, air supply hose
The entire hole in advance of perforation, starts air compressor machine 1, and compressed air flows through pressure reducing valve 3, compressed air decompression cooling by gas supply main pipe 2
Afterwards, gas manifold 4 is flowed into, heat exchange is carried out in mass concrete 7 by air supply hose 5, that is to say, that air supply hose 5
The air conveyed does not contact directly with 6 inner wall of hole in advance, but in be spaced the tube wall of one layer of air supply hose, compressed air
The heat of hydration for absorbing concrete achievees the purpose that reduce concrete inside and outside temperature difference, prevents mass concrete from cracking.
Relative to the method for the cooling mass concrete of recirculated cooling water, the air supply hose 5 of the utility model can be extracted out
Recycling, does not need recirculated cooling water, saves lot of materials and water resource, and the investment of compressed air unit and pipeline at
This is relatively low.In addition, since the air that air supply hose 5 is conveyed does not contact directly with 6 inner wall of hole in advance, air supply hose 5
Therefore substantially a kind of heat exchanger is not required to the deliberately moisturizing in hole 6 in advance, the coagulation around hole 6 is opened in cooling to cold air in advance indirectly
Soil, the case where can be avoided in pre- hole moisturizing not in time and cause the pre- cracking of hole 6 or abrasion, indirect good cooling results.
With reference to Fig. 1, based on the compressed air throttle effect indirect cooling device of mass concrete maintenance, including air compressor machine
1, main pipe 2, pressure reducing valve 3, gas manifold 4, air supply hose 5, in advance hole 6 and mass concrete 7 are supplied；
Mass concrete 7 reserves multiple pre- holes 6, and each pre- hole 6 penetrates through the left and right sides of mass concrete 7；

Need to illustrate: air supply hose 5 can be the tubing of steel pipe, plastic tube or other materials；Air compressor machine 1 can be air blower
Or compressed air is otherwise provided, have no effect on the essentiality content of the utility model.
Referring to attached drawing, work progress are as follows: temperature sensitive probe 8 and signal wire are embedded in concrete blinding by design requirement first
Interior, temperature sensitive probe 8 is generally embedded at concrete core position and external packet, in order to measure the temperature difference inside and outside concrete；
Then, it is poured concrete and constantly rotates drawing core pipe, until concrete final set, concrete no longer slump；Then extraction is taken out
Core pipe is formed the pre- hole 6 by design requirement in concrete in this way；
The signal wire of temperature sensitive probe 8 is connected to display and observes the concrete temperature that each temperature sensitive probe 8 transmits, together
When installation air compressor machine 1, gas supply main pipe 2, pressure reducing valve 3, gas manifold 4, the gas outlet of air supply hose 5 is protruded into pre- hole 6, and
Hole can entirely be opened in advance by passing through air supply hose, and starting air compressor machine 1 cools down to inside concrete, if the temperature difference inside and outside concrete is big
In 25 degree, then need to increase the air demand of air compressor machine 1, temperature difference of the fast cooling inside and outside concrete is less than 25 degree, use
State method cooling terminates until the concrete curing phase, while can also be thorough in conjunction with the concrete curing method of other coverings, moisturizing
Bottom prevents mass concrete from cracking, finally when concrete curing is completed, with pre- hole 6 of cement slurry closure.
Need to illustrate: such mode is not required to the deliberately moisturizing in pre- hole 6, and cold air is indirectly cooling to open mixing around hole 6 in advance
Solidifying soil, when can be avoided direct cooling, moisturizing not in time, causes the pre- cracking of hole 6 or abrasion, cooling is more straight indirectly in hole in advance
Connect good cooling results.
Certainly, after the completion of indirect cooling device cool down indirectly to concrete, further concrete can be carried out
Insulated curing, at this point, settable water charging system；Water charging system includes replenishing water tank of water, moisturizing water pump and moisturizing general pipeline；Moisturizing water pump
