Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a dam panel concrete cooling device. Background Art

[0002] At present, the construction of large-volume concrete is usually involved in the field of dam construction. How to limit the cracking of the dam concrete panel and improve the durability of the slope protection board concrete is the key to the safe operation of the dam. The temperature stress inside the large-volume concrete is one of the main reasons for the cracking of the concrete itself. Especially during the construction of large-volume concrete, the hydration of the concrete will generate a large amount of heat. If the heat cannot be effectively and evenly dissipated, a large temperature stress will be formed, which will cause the concrete to crack, and then reduce the construction quality. In response to the above situation, the existing practice is to pre-embed cold water pipes in the large-volume concrete to cool the concrete. For example, the utility model patent with announcement number CN207553102 involves a crack prevention and control structure for continuous cooling of large-volume concrete, which uses a method of setting cold water pipes in the large-volume concrete to cool the large-volume concrete. However, the cooling water pipe structure in the existing scheme is too simple, and the cooling efficiency of the large-volume concrete is low, resulting in the accumulation of temperature stress inside the concrete, causing cracking.

[0019] Figure 2 for Figure 1 AA section view of the . DETAILED DESCRIPTION

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0021] like Figure 1 and Figure 2As shown, the utility model provides a cooling device for dam panel concrete 3, including: a serpentine steel pipe 4, which is pre-buried in the dam panel concrete 3, and the two ends of the serpentine steel pipe 4 are respectively exposed on two opposite surfaces of the dam panel concrete 3, the serpentine steel pipe 4 includes a plurality of straight parts 5 and a plurality of bent parts 6, and every two adjacent straight parts 5 are connected by a bent part 6, and the number of the straight parts 5 is one more than the number of the bent parts 6; a U-shaped steel pipe 10, which is pre-buried in the dam panel concrete 3, and a group of U-shaped steel pipes 10 is provided on each straight part 5 of the plurality of straight parts 5, and the end of each U-shaped steel pipe 10 is connected to the corresponding straight part 5, so that each U-shaped steel pipe 10 is connected to the corresponding straight part 5; a cooling water pump 1, which is connected to one end of the serpentine steel pipe 4 through the water injection pipe 2.

[0022] When cooling the dam panel concrete 3, a cooling water pump 1 supplies water to one end of the serpentine steel pipe 4 through the water injection pipe 2. The cooling water flows through the serpentine steel pipe 4 into the U-shaped steel pipe 10. The serpentine steel pipe 4 and the U-shaped steel pipe 10 together cool the concrete, and the heat-exchanged water flows out through the other end of the serpentine steel pipe 4. The serpentine steel pipe 4 includes multiple straight sections 5 and multiple curved sections 6. That is, it extends in a curved manner within the concrete, which can extend the extension path within the concrete, increase the contact area with the concrete, and thus improve the cooling efficiency. In addition, a set of U-shaped steel pipes 10 is set in each straight section 5 of the serpentine steel pipe 4. When the cooling water enters the serpentine steel pipe 4, a portion of the cooling water will flow into the U-shaped steel pipe 10. Here, the U-shaped steel pipe 10 is similar to the heat dissipation fins of the serpentine steel pipe 4, which can further increase the contact area with the concrete and improve the cooling efficiency.

[0024] The U-shaped steel tubes 10 are arranged perpendicular to the serpentine steel tubes 4, defining another vertical heat dissipation surface, thereby improving the cooling efficiency of the concrete. Furthermore, the two adjacent sets of U-shaped steel tubes 10 extend in opposite directions, which can expand the heat dissipation surface of the concrete and improve the cooling efficiency.

[0025] In a preferred embodiment, in the cooling device for the dam panel concrete 3, every two adjacent straight sections 5 in the multiple straight sections 5 are connected together by a group of connecting steel bars 7, the group of connecting steel bars 7 is perpendicular to the corresponding two straight sections 5 in the plane, and the group of connecting steel bars 7 is evenly distributed relative to the corresponding two straight sections 5, the group of connecting steel bars 7 includes multiple connecting steel bars 7, and every two adjacent groups of connecting steel bars 7 are staggered with each other.

[0026] Connecting two adjacent straight sections 5 with connecting steel bars 7 can improve the strength of the serpentine steel pipe 4.

[0029] In a preferred embodiment, in the dam panel concrete 3 cooling device, the outer wall of the serpentine steel pipe 4 is provided with a serpentine reinforcement steel bar 8, and the serpentine reinforcement steel bar 8 is arranged along the serpentine steel pipe 4 and welded to the serpentine steel pipe 4.

[0030] The serpentine reinforcement steel bar 8 can enhance the strength of the serpentine steel pipe 4, and also help to increase the heat dissipation area and improve the cooling efficiency.

[0031] In a preferred embodiment, in the cooling device for the dam panel concrete 3, the other end of the serpentine steel pipe 4 is connected to the wastewater collection tank 9 through a drainage pipe.

[0032] The wastewater after heat exchange is collected in the wastewater collection tank 9, and can be re-input into the serpentine steel pipe 4 after heat exchange cooling for circulation cooling.

[0033] In a preferred embodiment, in the cooling device for the dam panel concrete 3 , the water injection pipe 2 is coiled around one side surface of the dam panel concrete 3 .

[0034] The water injection pipe 2 is placed on one side of the dam panel concrete 3, which can also play a role in cooling the concrete surface.

[0035] To sum up, the utility model pre-buries a serpentine steel pipe inside the dam panel concrete. The serpentine steel pipe can extend the path length inside the concrete, increase the contact area with the concrete, and thus improve the cooling efficiency. At the same time, a U-shaped steel pipe is arranged in the straight part of the serpentine steel pipe to further increase the contact area with the concrete, improve the cooling efficiency, and ultimately achieve the purpose of improving construction quality.
