Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a cooling mechanism for controlling the temperature of large-volume concrete in bridge abutments. Background Technology

[0002] Bridge abutments are a crucial component of the bridge substructure, playing a vital role in transferring loads between the superstructure and the superstructure. They are typically reinforced concrete structures and often exhibit large volumes. Temperature control is essential for large-volume concrete because the cement hydration process releases a significant amount of heat. This internal heat buildup is difficult to dissipate quickly, leading to excessive temperature differences between the inside and outside, which can cause temperature cracks and affect the structure's strength and durability. Cooling mechanisms for bridge abutment large-volume concrete effectively regulate the internal temperature of the concrete, reduce the temperature difference between the inside and outside, prevent temperature cracks, and ensure the construction quality of the bridge abutment, enabling it to stably bear various loads transferred from the bridge superstructure over the long term. Cooling mechanisms typically include water pipe cooling systems, surface cooling materials, and air cooling systems. Water cooling, specifically water pipe cooling systems, involves pre-embedding cooling water pipes inside the concrete and using circulating cooling water to absorb heat from the concrete's interior. It offers good temperature control and high flexibility.

[0003] Cooling mechanisms for controlling the temperature of large-volume concrete in bridge piers typically include cooling water pipes, inlet and outlet ports, a water circulation system, and a temperature monitoring device. The cooling water pipes are installed inside the concrete to absorb heat. The inlet and outlet ports connect to an external water circulation system, which consists of a water pump, a water tank, and a cooling tower. This system circulates and cools the cooling water. The temperature monitoring device monitors the temperature. Its working principle is that when the temperature rises due to the heat of hydration after the concrete is poured, the water pump sends cooling water from the water tank into the cooling water pipes. The cooling water absorbs heat from the concrete, flows out, is cooled by the cooling tower, and then returns to the water tank for reuse, thereby reducing the internal temperature of the concrete.

[0004] In existing technologies, due to the limited contact area between water pipes and concrete, heat transfer efficiency is restricted, making it difficult to fully absorb heat from the inside of the concrete. This results in poor cooling effect of some cooling mechanisms, leading to excessive temperature difference between the inside and outside of the concrete, generating temperature stress, which in turn causes cracks and reduces the strength and durability of the concrete structure. Therefore, a cooling mechanism for controlling the temperature of large-volume concrete in bridge abutments is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cooling mechanism for controlling the temperature of large-volume concrete in bridge abutments, aiming to improve the problem of poor cooling effect in some existing cooling mechanisms.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cooling mechanism for controlling the temperature of large-volume concrete in bridge abutments includes a base, a foundation pile fixedly connected to the top of the base, a heat dissipation mechanism fixedly connected to the inner wall of the foundation pile, and a water collection mechanism fixedly connected to the outer wall of the foundation pile.

[0008] The heat dissipation mechanism includes multiple cooling pipes, the outer walls of which are fixedly connected to the inner wall of the pile cap, and multiple heat dissipation fins are fixedly connected to the outer walls of the cooling pipes. The outer surface of the heat dissipation fins is serrated. Multiple ventilation slots are provided in the middle of the pile cap, and circulation components are fixedly connected to both ends of the cooling pipes.

[0009] As a further description of the above technical solution:

[0010] The circulation assembly includes two water storage tanks, with one end of each water storage tank fixedly connected to the two ends of a plurality of cooling pipes. A water pump is fixedly connected to the inner wall of each water storage tank, and the output end of the water pump is directly opposite the inlet of the cooling pipe.

[0011] As a further description of the above technical solution:

[0012] The water collection mechanism includes a water collection tank, the inner wall of which is fixedly connected to the outer wall of the pier pile, two floor drains are respectively provided at both ends of the bottom of the water collection tank, and two filter boxes are detachably connected to the bottom of the water collection tank.

[0013] As a further description of the above technical solution:

[0014] The top of the filter box is threaded with multiple screws, and the top of the multiple screws is threaded to the bottom of the water collection tank.

[0015] As a further description of the above technical solution:

[0016] Multiple cooling pipes are evenly distributed inside the pile cap, and the cooling pipes are distributed in a serpentine pattern.

[0017] As a further description of the above technical solution:

[0018] The outer walls of the plurality of heat dissipation fins are fixedly connected to the inner wall of the pile cap, and the heat dissipation fins are evenly distributed along the direction of the cooling pipe;

[0019] As a further description of the above technical solution:

[0020] The water collection tank is shaped like an open trumpet, and the top openings of the two filter boxes correspond to the bottom openings of the two floor drains, respectively.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, a water pump drives the cooling medium in the water storage tank to flow into the cooling pipe. The cooling pipe, with its serpentine structure and uniform distribution, facilitates full heat exchange between the cooling medium and the interior of the bridge abutment pile. Simultaneously, the heat dissipation fins increase the contact area as heat is conducted, enhancing heat transfer and thus reducing the internal temperature of the concrete. Then, external air is drawn into the interior through the ventilation slot in the middle of the bridge abutment pile, carrying away some of the heat. Furthermore, by increasing the contact area between the cooling mechanism and the bridge abutment, the cooling effect on the large volume concrete of the bridge abutment is enhanced in all aspects, achieving effective temperature control. This ensures the quality of the large volume concrete of the bridge abutment, avoids potential hazards such as cracks caused by temperature issues, and makes the structure stable and reliable. This contributes to the smooth progress of the entire bridge construction and improves construction efficiency.

[0025] 2. In this utility model, condensate on the concrete surface and water accumulated on the bridge are carried by gravity through drainage channels and the outer wall of the pier pile into the water collection tank for collection. Then, the water automatically flows into the filter box through the floor drain at the bottom of the water collection tank. After impurities are intercepted by the filter plate at the bottom of the filter box, the filtered water falls into the storage tank under gravity, realizing automatic replenishment of cooling water source, ensuring continuous supply of cooling medium, maintaining stable operation of the cooling system, ensuring uninterrupted temperature control of large-volume concrete of bridge pier, improving the stability of temperature control effect, and reducing additional water supply costs and resource waste.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 2 to 4 This utility model provides an embodiment of a cooling mechanism for controlling the temperature of large-volume concrete bridge abutments. The mechanism includes a base 1, the bottom of which is buried in the soil. The base 1 plays a crucial role in stabilizing the entire cooling mechanism. Burying its bottom in the soil utilizes the supporting force and friction of the soil to effectively prevent displacement or shaking caused by various external forces during operation. A foundation pile 2 is fixedly connected to the top of the base 1. A heat dissipation mechanism is fixedly connected to the inner wall of the foundation pile 2, and a water collection mechanism is fixedly connected to the outer wall. The foundation pile 2 serves as the main structure supporting the heat dissipation and water collection mechanisms. Its internal space is rationally utilized to arrange heat dissipation-related components, while its external structure works in conjunction with the water collection mechanism, effectively integrating different aspects of the temperature control process and improving the overall functionality and coordination of the cooling mechanism.

[0034] The heat dissipation mechanism includes multiple cooling pipes 5, whose outer walls are fixedly connected to the inner wall of the pile cap 2. These cooling pipes 5 are evenly distributed within the pile cap 2 in a serpentine pattern, increasing their length and contact area within the pile cap 2. During operation, the cooling medium flows through the cooling pipes 5. Due to their longer path and larger contact area, they can more effectively exchange heat with the interior of the pile cap 2, absorbing heat dissipated by the concrete through the pipe walls, thus effectively reducing the internal temperature of the concrete. The even distribution of the cooling pipes 5 ensures uniform heat dissipation throughout the pile cap 2, preventing localized overheating or undercooling, resulting in more stable and reliable temperature control, and contributing to improved quality and durability of the large-volume concrete in bridge pile caps.

[0035] Multiple heat dissipation fins 6 are fixedly connected to the outer wall of the cooling pipe 5. These fins are also fixedly connected to the inner wall of the pile cap 2. The fins 6 are evenly distributed along the cooling pipe 5 and have a serrated outer surface. Their main working principle is to enhance heat transfer efficiency by increasing the heat dissipation surface area. When heat from the cooling pipe 5 is conducted to the fins 6, their serrated surface further increases the contact area with the surrounding concrete, thus enhancing the heat exchange effect. Multiple ventilation slots 7 are provided in the middle of the pile cap 2, providing good airflow channels inside. During heat dissipation, external air can enter the pile cap 2 through the ventilation slots 7, helping to remove more heat and further improving the heat dissipation effect. Circulation components are fixedly connected to both ends of the cooling pipe 5.

[0036] The circulation assembly includes two water storage tanks 3, with their adjacent ends fixedly connected to both ends of multiple cooling pipes 5. The water storage tanks 3 serve as storage containers for the cooling medium, providing a stable water source or other cooling medium supply for the entire cooling cycle. The bottoms of the two water storage tanks 3 are fixedly connected to the top of the base 1, ensuring stability during operation. A water pump 4 is fixedly connected to the inner wall of each water storage tank 3, with its output end facing the inlet of each cooling pipe 5. When cooling of the pier cap is required, the water pump 4 starts, drawing the cooling medium from the water storage tanks 3 and pressing it into the cooling pipes 5. The pressure provided by the water pump 4 causes water to flow in a specific direction within the cooling pipes 5, flowing from one water storage tank 3 into the cooling pipe 5. After heat exchange with the pier piles 2, the water flows into the other water storage tank 3, ensuring that the cooling medium continuously removes heat from the concrete and effectively controls the temperature of the large-volume concrete of the bridge pier cap.

[0037] Reference Figures 1 to 2 The water collection mechanism includes a water collection tank 8, whose inner wall is fixedly connected to the outer wall of the pile cap 2. The water collection tank 8 is shaped like an open trumpet, which allows for more effective water collection. Its larger opening area can cover a wider area, ensuring that water does not flow around and affect the construction site environment or other equipment and facilities. During construction, water accumulated on the bridge will flow down the outer wall of the pile cap 2 through drainage channels and condensation on the concrete surface. The trumpet-shaped opening of the water collection tank 8 can collect these water flows, preventing water accumulation hazards on the construction site, keeping the construction site dry and clean, and facilitating the smooth progress of other construction procedures. Two floor drains 9 are installed at both ends of the bottom of the water collection tank 8. The function of the floor drains 9 is to guide the water collected by the water collection tank 8 to the subsequent structure.

[0038] Two filter boxes 10 are detachably connected to the bottom of the water collection tank 8. The top openings of the two filter boxes 10 correspond to the bottom openings of the two floor drains 9, respectively. The filter boxes 10 play a crucial role in purifying water quality. When water flows through the floor drains 9 into the filter boxes 10, the filter plates inside the filter boxes 10 can intercept impurities in the water, and the filtered water automatically falls into the water storage tank 3 to replenish the cooling medium. The top of the filter boxes 10 is threaded with multiple screws 11, and the top of the screws 11 is threaded to the bottom of the water collection tank 8. When it is necessary to clean or replace the filter medium inside the filter boxes 10, simply unscrew the screws 11 to easily remove the filter boxes 10 for operation, thereby ensuring that the filter boxes 10 always maintain good filtration performance and extending the service life of the entire water collection mechanism.

[0039] Working Principle: When cooling of the bridge abutment is required, water pump 4 starts, driving the cooling medium in water tank 3 to flow. The cooling medium is drawn from water tank 3 and forced into cooling pipe 5, where it flows in a specific direction. The cooling pipe 5 is serpentinely distributed and evenly placed inside the abutment pile 2. Its serpentine structure allows the cooling medium to exchange heat with the interior of the abutment pile 2 over a longer path and with a larger contact area, effectively absorbing the heat emitted by the concrete and reducing its internal temperature. The even distribution ensures uniform heat dissipation. The heat dissipation fins 6 on the outer wall of the cooling pipe 5 heat up as heat is conducted. Their serrated surface increases the contact area with the surrounding concrete, thereby enhancing heat transfer efficiency. The ventilation slot 7 in the middle of the abutment pile 2 draws external air into the interior. The airflow carries away more heat, further improving the heat dissipation effect. The coordinated operation of these structures comprehensively enhances the cooling effect on the large volume of concrete in the bridge abutment, achieving effective temperature control.

[0040] In terms of water replenishment, condensate on the concrete surface and water accumulated on the bridge flow down the outer wall of the pile cap 2 through the drainage channel under the action of gravity, into the funnel-shaped water collection tank 8. The water collection tank 8, with its large opening area and special shape, gathers the water flow. Then, the water flow flows through the drain 9 at the bottom of the water collection tank 8 under the action of gravity. The drain 9 drives the water flow into the opening at the top of the corresponding filter box 10. Under the action of pressure difference, the water flow passes through the filter plate inside the filter box 10. The filter plate intercepts impurities in the water. The filtered water automatically falls into the storage tank 3 under the action of gravity, thus realizing the automatic replenishment of the cooling water source. At the same time, when it is necessary to maintain the filter box 10, the screw 11 is turned to disengage it from the bottom of the water collection tank 8, so that the filter box 10 can be easily removed for cleaning or replacement of the filter media, ensuring the continuous and effective operation of the filter box 10, maintaining the stable operation of the entire water collection mechanism, and providing a reliable guarantee for the replenishment of the cooling media.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
