AI Technical Summary
Most existing cooling pipes directly inject water from the outside for cooling, which prevents the heat in the deep concrete from being effectively dissipated, resulting in low cooling efficiency and long cooling time.
The system employs a conveying and cooling pipe structure with built-in insulation material. Cooling water is transported to the deep layers of the concrete through the conveying pipes, and the pressure of the cooling water is used to cool the concrete from the deep layers until it rises to the shallow layers and is discharged, thus avoiding heat accumulation in the deep layers.
This method achieves preferential cooling of the deep layers of concrete, improves cooling efficiency, shortens the overall cooling time, and avoids the reduction in cooling effect caused by the accumulation of heat in the deep layers.

TECHNICAL FIELD
[0001] The present application relates to the technical field of concrete cooling, in particular to a mass concrete cooling structure. BACKGROUND
[0002] Mass concrete occupies an important position in modern engineering construction, and the concrete is a brittle material. After the mass concrete is poured, the internal temperature of the mass concrete rises sharply due to the hydration heat of cement, so that the temperature difference between the inside and outside of the mass concrete is large, and a large number of temperature cracks are easily caused in the mass concrete. The large temperature cracks directly affect the safety performance of the concrete structure during the construction period and the operation process.
[0003] In recent years, post-cooling technology has been widely used in the control of the internal temperature field of mass concrete. However, the cooling range of ordinary smooth water pipes is small, and only the concrete near the water pipe has good cooling effect, while the cooling effect of the part far away from the water pipe is poor. At the same time, due to the small thermal conductivity coefficient of the concrete itself, the heat conduction time of the concrete region far away from the cooling water pipe region is long. Most of the existing cooling pipes directly inject water from the outside and flow along the pipe to cool. When the cooling water flows from the outside to the deep concrete, it has passed a distance, so that the temperature of the cooling water reaching the deep layer rises, and the heat of the deep concrete is dissipated, resulting in that the heat of the deep concrete cannot be effectively dissipated. SUMMARY
[0004] The embodiment of the present application provides a mass concrete cooling structure to solve the problem that most of the existing cooling pipes in the related art directly inject water from the outside and flow along the pipe to cool. When the cooling water flows from the outside to the deep concrete, it has passed a distance, so that the temperature of the cooling water reaching the deep layer rises, and the heat of the deep concrete is dissipated, resulting in that the heat of the deep concrete cannot be effectively dissipated.
[0005] The first aspect of the embodiment of the present application provides a mass concrete cooling structure, comprising:
[0006] The cooling main pipe comprises a cooling pipe arranged in the concrete and a conveying pipe arranged in the cooling pipe. The conveying pipe is in communication with the cooling water outside the pipe so that the cooling water is conveyed to one end of the cooling pipe located in the deep layer of the concrete, and then discharged from the other end of the cooling pipe away from the concrete.
[0007] In some embodiments, the inner wall of the one end of the cooling pipe near the deep layer of the concrete is arc-shaped.
[0008] In some embodiments, a first water outlet is formed in the side wall of the one end of the cooling pipe away from the concrete.
[0009] One end of the conveying pipe extends out of the cooling pipe and is provided with a water inlet, and the other end is provided with a second water outlet.
[0010] In some embodiments, the diameter of the conveying pipe is smaller than that of the cooling pipe, so that a cooling channel is formed between the conveying pipe and the cooling pipe.
[0011] In some embodiments, the pipe wall of the conveying pipe is made of heat insulation material.
[0012] In some embodiments, the cooling main pipe has multiple pipes which are arranged in the concrete in intervals.
[0013] The second aspect of the embodiments of the present application provides a mass concrete cooling structure, which comprises:
[0014] The cooling main pipe comprises a conveying pipe which is connected to an external cooling water source and used to convey cooling water into the concrete to cool the concrete, and two cooling pipes which are arranged on the two sides of the conveying pipe respectively, and one end of the cooling pipe close to the deep layer of the concrete is connected to and communicated with one end of the conveying pipe close to the deep layer of the concrete.

[0019] One end of the conveying pipe close to the deep layer of the concrete is provided with a second water outlet, and the other end is provided with a second water inlet.
[0020] The technical scheme provided by the present application has the following beneficial effects:
[0021] When the concrete needs to be cooled, the cooling water is injected through the conveying pipe. Since the material of the conveying pipe is heat insulation material, the cooling water in the conveying pipe does not absorb too much heat of the concrete during the flowing process, so that the cooling water with a certain cooling temperature can be conveyed to the deep layer of the concrete, and then conveyed into the cooling pipe. When the cooling water is conveyed into the cooling pipe, the pressure generated by the continuously injected cooling water makes the cooling water rise along the cooling pipe, and the cooling starts from the deep layer of the concrete and then rises to the shallow layer of the concrete and is discharged. In this way, the deep layer of the concrete can be cooled preferentially, the continuous heat accumulation in the deep layer of the concrete is avoided, the heat is not easily dissipated, the cooling effect is reduced, the cooling of the concrete starts from the shallow layer, the cooling efficiency of the deep layer of the concrete is low, and the overall cooling time is long.

[0026] In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort are within the scope of protection of the present application.
[0027] The embodiments of the present application provide a mass concrete cooling structure, which can solve the problem that most of the existing cooling pipes are directly injected with water from the outside to flow along the pipe for cooling. When the cooling water flows from the outside to the deep concrete, it has already traveled a distance, so that the temperature of the cooling water reaching the deep layer rises, and the heat of the deep concrete is dissipated, resulting in that the heat of the deep concrete cannot be effectively dissipated.
[0028] Referring to Figure 1 The first aspect of the embodiments of the present application provides a mass concrete cooling structure, which comprises:
[0029] The cooling main pipe comprises a cooling pipe 5 arranged in the concrete and a conveying pipe 1 arranged in the cooling pipe 5. The conveying pipe 1 is in communication with the cooling water outside the pipe to convey the cooling water to one end of the cooling pipe 5 located in the deep layer of the concrete, and then discharge the cooling water from the other end of the cooling pipe 5 away from the concrete.
[0030] In the embodiments, the pipe wall material of the conveying pipe 1 is a heat insulation material.
[0031] In the embodiments, the cooling main pipe has a plurality of cooling pipes arranged in the concrete at intervals.
[0032] In this embodiment, the first water outlet is arranged on the side wall of the cooling pipe 5 away from the concrete, one end of the delivery pipe 1 extends out of the cooling pipe 5 and is provided with a water inlet, and the other end is provided with a second water outlet.
[0033] When the concrete needs to be cooled, the cooling water is injected through the delivery pipe 1. Since the material of the delivery pipe 1 is heat-insulating material, the cooling water in the delivery pipe 1 does not absorb too much heat of the concrete during flowing, so that the cooling water at a certain cooling temperature can be delivered to the deep position of the concrete, and then delivered into the cooling pipe 5. When delivered into the cooling pipe 5, the cooling water rises along the cooling pipe 5 under the pressure generated by the continuously injected cooling water, and cools the concrete from the deep position to the shallow position and then is discharged, so that the deep position of the concrete is cooled preferentially, and the continuous heat accumulation at the deep position is avoided, and the heat is not easily dissipated, which reduces the cooling effect. The cooling of the concrete from the shallow position to the deep position is avoided, the cooling efficiency of the deep concrete is improved, and the overall cooling time is shortened.
[0034] The cooling pipe 2 leaks out of the concrete layer at the end away from the deep position of the concrete, and the end is closed. The delivery pipe 1 is inserted into the cooling pipe 5 from the closed end and is fixedly connected with the closed end, so as to avoid falling and shaking of the delivery pipe 1. The end of the delivery pipe 1 inserted into the cooling pipe 5 is spaced apart from the bottom of the cooling pipe 5, so that the delivery pipe 1 can discharge the cooling water into the cooling pipe 5.
[0035] The plurality of cooling pipes are arranged in the mass concrete, so that the mass concrete can be cooled at multiple positions at the same time.
[0036] The plurality of cooling pipes are arranged in the mass concrete, so that the mass concrete can be cooled at multiple positions at the same time.
[0037] In some optional embodiments, as shown in Figure 1 The inner wall of the end of the cooling pipe 5 close to the deep position of the concrete is arc-shaped.
[0038] The first water outlet is arranged on the side wall of the end of the cooling pipe 5 leaking out of the concrete layer, so that the cooling water flows from bottom to top and is discharged. The inner wall of the end of the cooling pipe 5 close to the deep position of the concrete is arc-shaped, so that the impact force of the cooling water is reduced and buffered after the delivery pipe 1 discharges the cooling water.
[0039] In some optional embodiments, as shown in Figure 1As shown, the volume concrete cooling structure, the diameter of the delivery pipeline 1 is smaller than the cooling pipeline 5, so that the delivery pipeline 1 and the cooling pipeline 5 form a cooling channel 8, the gap between the output pipeline 2 and the cooling pipeline 5 is the cooling channel 8 after the output pipeline 2 is inserted into the cooling pipeline 5, the cooling water is discharged from the output pipeline 2 and enters the cooling channel 8, and the cooling heat exchange is performed on the cooling of the concrete deep layer to the shallow layer.
[0040] Referring to Figure 2 As shown, the second aspect of the embodiment of the application provides a volume concrete cooling structure, comprising:
[0041] The cooling main pipe comprises a delivery pipeline 1 for conveying the cooling water to the concrete to cool the concrete, and two cooling pipelines 5 arranged on both sides of the delivery pipeline 1, and the end of the cooling pipeline 5 close to the deep layer of the concrete is connected and communicated with the end of the delivery pipeline 1 close to the deep layer of the concrete.
[0042] In the embodiment, the pipe wall of the delivery pipeline 1 is made of heat insulation material.
[0043] In the embodiment, the end of the cooling pipeline 5 close to the deep layer of the concrete is provided with a first water inlet, and the other end is provided with a first water outlet.
[0044] The end of the delivery pipeline 1 close to the deep layer of the concrete is provided with a second water outlet, and the other end is provided with a second water inlet.
[0045] The cooling pipeline 5 and the delivery pipeline 1 are independent pipelines, the cooling pipeline 2 is arranged on both sides of the delivery pipeline 1, the end of the cooling pipeline 5 and the delivery pipeline 1 is arranged in the deep layer of the concrete, and the other end is arranged out of the concrete layer, the end of the cooling pipeline 5 and the delivery pipeline 1 arranged in the deep layer of the concrete is connected and communicated through the second water outlet and the second water inlet, the side wall of the end of the cooling pipeline 5 arranged out of the concrete layer is provided with the first water outlet, and the end of the delivery pipeline 1 arranged out of the concrete layer is provided with the first water inlet.
[0046] When the delivery pipeline 1 is injected with cooling water, the cooling water flows into the cooling pipeline 5, and then flows out of the cooling pipeline 5, because the material of the delivery pipeline 1 is heat insulation material, the cooling water in the delivery pipeline 1 does not absorb too much heat of the concrete during the flowing process, so that the cooling water with a certain cooling temperature can be conveyed to the deep layer of the concrete, and when the cooling water is conveyed into the cooling pipeline 5, the pressure generated by the continuously injected cooling water is used to make the cooling water rise along the cooling pipeline 5, so that the cooling starts from the deep layer of the concrete and rises to the shallow layer of the concrete and then is discharged, so that the deep layer of the concrete is cooled preferentially, the continuous heat accumulation in the deep layer of the concrete is avoided, the heat is not easily dissipated, the cooling effect is reduced, the cooling starts from the shallow layer of the concrete, the cooling efficiency of the deep layer of the concrete is low, and the overall cooling time is long.
[0047] In some alternative embodiments, referring to Figure 2 As shown, in the mass concrete cooling structure, the cooling pipe 5 includes a continuous bending section 7 and a straight section 6, the cooling pipe 5 is located at a deep position as the continuous bending section 7, which can also be understood as a continuous S shape, so that the deep concrete can increase the contact area and heat exchange efficiency of the cooling water, so as to accelerate the cooling of the deep concrete and improve the overall cooling efficiency of the mass concrete.
[0048] In some alternative embodiments, referring to Figure 2 As shown, in the mass concrete cooling structure, the cooling main pipe is multiple and is spaced apart in the concrete, and the multiple cooling main pipes are spaced apart in the mass concrete, so that the concrete at multiple positions can be cooled at the same time.
[0049] Working principle and process of the present application:
[0050] When the conveying pipe 1 injects cooling water, the cooling water flows into the cooling pipe 5, and then from the cooling pipe 5, because the material of the conveying pipe 1 is a heat insulation material, so the cooling water in the conveying pipe 1 will not absorb too much heat of the concrete during the flow, that is, the cooling water with a certain cooling temperature can be transported to the deep position of the concrete, and when it is transported to the cooling pipe 5, the pressure generated by the continuous injection of the cooling water is used to make the cooling water rise along the cooling pipe 5, and the cooling starts from the deep position of the concrete, and then rises to the shallow position of the concrete and is discharged, so that the deep position of the concrete can be cooled preferentially, and the continuous heat accumulation at the deep position can be avoided, and the heat is not easy to dissipate, which reduces the cooling effect, and the cooling of the concrete from the shallow position can be avoided, which reduces the cooling efficiency of the deep concrete and prolongs the overall cooling time.
