TECHNICAL FIELD

[0001] The utility model belongs to the technical field of construction tools, especially relates to big volume concrete pouring intelligent temperature control guide pipe. BACKGROUND

[0002] In the process of large area concrete pouring, how to prevent concrete cracking is an important process, the existing technology is that the heat preservation blanket is covered on the concrete to carry out temperature control or a plurality of guide pipes are directly embedded in the concrete and temperature control is carried out by circulating water, the latter can carry out synchronous heating to the concrete inside, and the temperature control effect is better.

[0003] When the temperature of the concrete is controlled through the guide pipe, the operation is usually that the guide pipe is pre-embedded into the pouring area of the concrete, then circulating water is injected into the guide pipe, and the guide pipe is heat exchanged through the circulating water, so that the temperature control effect is achieved, but in the actual use process, only the thermocouple and the like temperature sensor is usually used to monitor the temperature of the concrete surface, which leads to that the temperature of the inside of the concrete cannot be monitored, and the heat transfer needs a certain time, and the temperature difference between the inside of the concrete and the outside is large, which leads to that the heat exchange is excessive, and the problem of concrete cracking is caused.
