Description

Technical Field

[0001] This utility model relates to the field of building concrete construction technology, and in particular to a heat dissipation device for the hydration heat of cast-in-place bridge piers. Background Technology

[0002] In bridge construction, the cast-in-place process has become the mainstream method for bridge pier construction because it enables the integral forming of bridge piers, ensuring structural integrity and load-bearing strength, and is adaptable to the design requirements of piers with different cross-sectional shapes and heights. However, the concrete pouring process involves a hydration reaction that releases a large amount of heat. Due to the large volume of the piers and the poor thermal conductivity of concrete, heat easily accumulates inside, leading to a significant temperature difference between the inside and outside of the pier, which in turn generates temperature stress. When the temperature stress exceeds the tensile strength of the concrete, cracks will appear on the surface or inside of the pier, not only damaging the structural integrity but also reducing the pier's impermeability and durability, and even affecting the overall load-bearing safety and service life of the bridge.

[0003] To mitigate the negative impacts of hydration heat, various heat dissipation devices exist in existing technologies, such as water-cooling and air-cooling systems. Water-cooling systems primarily utilize cooling water pipes, which are often arranged in straight lines. This lack of adaptability to the internal heat distribution of concrete results in low heat dissipation efficiency and difficulty in quickly balancing the temperature difference between the inside and outside of the pier. Furthermore, sharp bends, low-lying sections, or insufficient slope in the cooling water pipes can cause water stagnation, preventing the timely removal of heat from the pier. This leads to heat accumulation inside the pier, generating thermal stress and reducing the structural strength of the pier. In addition, stagnant water can freeze and expand in low-temperature environments, potentially damaging the cooling pipes and the pier, thus reducing the pier's service life. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation device for the hydration heat of cast-in-place bridge piers, which can improve the heat dissipation efficiency of the hydration heat of the piers.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0007] A heat dissipation assembly includes multiple heat dissipation components. Each heat dissipation component includes a main water inlet pipe, at least one main water outlet pipe, multiple sub-water inlet pipes, and multiple cooling pipes. The main water inlet pipe is vertically connected to the multiple sub-water inlet pipes. Each sub-water inlet pipe is connected to a cooling pipe. Each cooling pipe extends horizontally, and the multiple cooling pipes are spaced apart vertically. The ends of the multiple cooling pipes away from the sub-water inlet pipes are connected to the main water outlet pipe, which extends vertically.

[0008] The fixing assembly includes two semi-circular fixing plates that are fixedly connected to form a cylindrical pouring space filled with concrete. Multiple heat dissipation components are spaced apart around the axis of the pouring space. The main water inlet pipe and the main water outlet pipe extend out of the fixing plates.

[0009] The aforementioned heat dissipation device for the hydration heat of cast-in-place bridge piers includes multiple cooling pipes spaced at intervals along the vertical direction, wherein the interval between the cooling pipes located in the middle region is smaller than the interval between the cooling pipes located at both ends.

[0010] The aforementioned heat dissipation device for the hydration heat of cast-in-place bridge piers includes two heat dissipation components arranged opposite each other. The main water inlet pipe of each heat dissipation component is close to the fixed plate, and the main water outlet pipe of each heat dissipation component is far away from the fixed plate.

[0011] The aforementioned heat dissipation device for the hydration heat of cast-in-place bridge piers includes two main water outlet pipes. Each cooling pipe includes a first arc-shaped portion, a second arc-shaped portion, and a third arc-shaped portion. The two second arc-shaped portions are respectively connected to the two ends of the first arc-shaped portion. Each second arc-shaped portion has a third arc-shaped portion connected to its end away from the first arc-shaped portion. The ends of the two third arc-shaped portions away from the second arc-shaped portions are respectively connected to the two main water outlet pipes. The concave surface of the first arc-shaped portion faces the concave surface of the second arc-shaped portion, and the concave surface of the first arc-shaped portion faces the convex surface of the third arc-shaped portion.

[0012] The aforementioned heat dissipation device for the hydration heat of cast-in-place bridge piers includes a fixing component that further includes fastening bolts. The fixing plate includes a mounting part with mounting holes. The fastening bolts can pass through the mounting holes of the two fixing plates to fix the two fixing plates together.

[0013] In the aforementioned heat dissipation device for the hydration heat of cast-in-place bridge piers, a plurality of mounting holes are arranged at intervals along the vertical direction in the mounting section.

[0014] The aforementioned heat dissipation device for the hydration heat of cast-in-place bridge piers further includes a first reinforcing plate, which is arc-shaped and surrounds the convex surface of the fixed plate.

[0015] The aforementioned heat dissipation device for the hydration heat of cast-in-place bridge piers further includes a second reinforcing plate that extends vertically and is fixedly connected to the convex surface of the fixing plate at intervals around the axis of the fixing plate, and the second reinforcing plate passes through the first reinforcing plate.

[0016] The aforementioned heat dissipation device for the hydration heat of cast-in-place bridge piers, wherein the main inlet pipe, the main outlet pipe, the sub-inlet pipe, and the cooling pipe are made of galvanized steel pipe.

[0017] The aforementioned heat dissipation device for the hydration heat of cast-in-place bridge piers further includes a sealing element. The sealing element is provided at the connection between the main water inlet pipe and the sub-water inlet pipe, at the connection between the sub-water inlet pipe and the cooling pipe, and at the connection between the cooling pipe and the main water outlet pipe.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a heat dissipation device for the hydration heat of cast-in-place bridge piers. In use, two fixed plates are connected, and the heat dissipation component is placed within the casting space. A main inlet pipe and a main outlet pipe are led out, and concrete is poured within the casting space to form the pier. Cooling water flows sequentially through the main inlet pipe, then through the sub-inlet pipe, the cooling pipe, and the main outlet pipe. The heat generated during the hydration of the concrete during cooling is transferred to the cooling water and then discharged through the main outlet pipe. Since multiple sub-inlet pipes and cooling pipes are arranged vertically, multiple cooling pipes can simultaneously cool multiple areas of the pier vertically, improving cooling efficiency. Simultaneously, the horizontal extension of multiple cooling pipes increases the contact area with the concrete, improving adaptability to the internal heat distribution of the concrete. This allows for simultaneous cooling of the entire concrete, reducing temperature differences between different parts of the concrete, preventing internal cracks, and improving the structural strength and service life of the pier. Furthermore, the main outlet pipe extends vertically, and due to gravity, the cooling water flows out naturally, eliminating the problem of cooling water stagnation. Attached Figure Description

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] The heat dissipation device for the hydration heat of cast-in-place bridge piers provided by this utility model can improve heat dissipation efficiency and avoid cooling water stagnation.

[0036] like Figures 1-7 As shown, the heat dissipation device for the hydration heat of cast-in-place bridge piers includes a heat dissipation component 1 and a fixing component 2. The heat dissipation component 1 includes multiple heat dissipation elements 11. Each heat dissipation element 11 includes a main water inlet pipe 111, at least one main water outlet pipe 112, multiple sub-water inlet pipes 113, and multiple cooling pipes 114. The main water inlet pipe 111 is vertically connected to multiple sub-water inlet pipes 113, and each sub-water inlet pipe 113 is connected to a cooling pipe 114. Each cooling pipe 114 extends horizontally and has multiple... Cooling pipes 114 are spaced apart in the vertical direction. One end of the multiple cooling pipes 114 away from the sub-inlet pipe 113 is connected to the main outlet pipe 112, which extends in the vertical direction. The fixing component 2 includes two semi-circular fixing plates 21. The two fixing plates 21 can be fixedly connected to form a cylindrical casting space. Concrete is poured into the casting space. Multiple heat dissipation components 11 are spaced apart around the axis of the casting space. The main inlet pipe 111 and the main outlet pipe 112 extend out of the fixing plate 21.

[0037] The heat dissipation device for hydration heat of cast-in-place bridge piers provided by this utility model involves fixing two plates 21 together, placing the heat dissipation component 1 in the casting space, and then leading out the main inlet pipe 111 and the main outlet pipe 112. Concrete is then poured in the casting space to form the pier. Cooling water flows sequentially through the main inlet pipe 111, through the sub-inlet pipe 113, the cooling pipe 114, and the main outlet pipe 112. The heat generated during the hydration of the concrete during cooling is transferred to the cooling water and then discharged through the main outlet pipe 112. Since multiple sub-inlet pipes 113 and cooling pipes 114 are arranged vertically, multiple cooling pipes 114 can simultaneously cool multiple areas of the pier in the vertical direction, improving cooling efficiency. At the same time, the multiple cooling pipes 114 extend horizontally, increasing the contact area with the concrete and improving the adaptability to the internal heat distribution of the concrete. This allows for simultaneous cooling of the entire concrete, reducing temperature differences between different parts of the concrete, preventing internal cracks in the concrete, and improving the structural strength and service life of the pier. In addition, the main outlet pipe 112 extends vertically, and the cooling water will flow out naturally due to gravity, so there is no problem of cooling water stagnation.

[0038] In this embodiment, the main inlet pipe 111, main outlet pipe 112, sub-inlet pipe 113, and cooling pipe 114 are made of galvanized steel pipe. The galvanized layer on the surface of the galvanized steel pipe forms anodized protection, preventing it from reacting with oxygen and minerals in the cooling water to cause oxidation corrosion and scaling. This reduces the risk of blockage caused by rust in the main inlet pipe 111, main outlet pipe 112, sub-inlet pipe 113, and cooling pipe 114, ensuring the cooling effect. Simultaneously, the galvanized steel pipe has good thermal conductivity, which improves the efficiency of heat transfer, thereby increasing the heat dissipation efficiency of the hydration heat of the pier column.

[0039] Furthermore, the heat dissipation device for the hydration heat of the cast-in-place bridge pier also includes sealing elements. Sealing elements are installed at the connection between the main inlet pipe 111 and the sub-inlet pipe 113, at the connection between the sub-inlet pipe 113 and the cooling pipe 114, and at the connection between the cooling pipe 114 and the main outlet pipe 112. These sealing elements prevent cooling water leakage, ensure efficient cooling water circulation, effectively reduce the temperature of the pier to prevent cracking, and also prevent leaked cooling water from corroding the internal supporting steel bars of the pier, thereby improving the structural strength and service life of the pier.

[0040] In this embodiment, the main water inlet pipe 111 is welded and fixed to the sub-water inlet pipe 113, the sub-water inlet pipe 113 is welded and fixed to the cooling pipe 114, and the cooling pipe 114 is welded and fixed to the main water outlet pipe 112. The welding connection is convenient and firm. The sealing element can be waterproof tape. The waterproof tape is wrapped around the connection between the main water inlet pipe 111 and the sub-water inlet pipe 113, the connection between the sub-water inlet pipe 113 and the cooling pipe 114, and the connection between the cooling pipe 114 and the main water outlet pipe 112 to improve the sealing performance.

[0041] In other embodiments, the sealant is also initially a sealant applied to the connection between the main water inlet pipe 111 and the sub-water inlet pipe 113, the connection between the sub-water inlet pipe 113 and the cooling pipe 114, and the connection between the cooling pipe 114 and the main water outlet pipe 112.

[0042] This embodiment does not specify the diameter of the main water inlet pipe 111, the main water outlet pipe 112, the sub-water inlet pipe 113, and the cooling pipe 114; the design can be based on the on-site construction conditions.

[0043] In this embodiment, see Figures 5 to 7 The cooling pipe 114 is designed with multiple arcs to avoid dead corners, reduce cooling water stagnation, and improve heat dissipation efficiency.

[0044] Specifically, the heat sink 11 includes two main water outlet pipes 112, and the cooling pipe 114 includes a first arc-shaped portion 1141, a second arc-shaped portion 1142, and a third arc-shaped portion 1143. The two second arc-shaped portions 1142 are respectively connected to both ends of the first arc-shaped portion 1141. Each second arc-shaped portion 1142 has a third arc-shaped portion 1143 connected to its end away from the first arc-shaped portion 1141. The ends of the two third arc-shaped portions 1143 away from the second arc-shaped portion 1142 are respectively connected to the two main water outlet pipes 112. The concave surface of the first arc-shaped portion 1141 faces the concave surface of the second arc-shaped portion 1142, and the concave surface of the first arc-shaped portion 1141 faces the convex surface of the third arc-shaped portion 1143. This improves heat dissipation efficiency.

[0045] The multi-segment arc design extends the flow path of the cooling water, thereby increasing the contact time between the cooling water and the hydration heat inside the pier, improving heat transfer efficiency, and thus improving the heat dissipation efficiency of the pier's hydration heat. Simultaneously, the concave surface of the first arc portion 1141 faces the concave surface of the second arc portion 1142, and the concave surface of the first arc portion 1141 faces the convex surface of the third arc portion 1143, ensuring smooth connection between the first arc portion 1141, the second arc portion 1142, and the third arc portion 1143, avoiding dead angles, reducing cooling water stagnation, and improving the pier's heat dissipation efficiency.

[0046] In other embodiments, the cooling pipes 114 can also be arranged in a serpentine pattern, with one end of the cooling pipe 114 connected to the sub-inlet pipe 113 and the other end connected to the main outlet pipe 112. Since the cooling pipe 114 has only one outlet, one main outlet pipe 112 can be provided, and the outlets of all cooling pipes 114 are connected to the main outlet pipe 112.

[0047] This embodiment does not specifically limit the number of heat sinks 11. For example, the heat dissipation assembly 1 includes two heat sinks 11, which are arranged opposite to each other. The main water inlet pipe 111 of each heat sink 11 is close to the fixing plate 21, and the main water outlet pipe 112 of each heat sink 11 is far away from the fixing plate 21. The main water inlet pipe 111 and the main water outlet pipe 112 are arranged far apart, which can increase the flow time of cooling water from the self-inlet pipe 111 to the main water outlet pipe 112, so that the cooling water carries more heat generated by the hydration reaction of the pier column, thereby improving the heat dissipation efficiency of the pier column and improving the structural strength and service life of the pier column.

[0048] Furthermore, multiple cooling pipes 114 are arranged vertically at intervals, with the spacing between the cooling pipes 114 in the middle region being smaller than that between the cooling pipes 114 at both ends. Since the density of the middle part of the pier is higher than that of the ends after pouring, the heat generated by the hydration reaction in the middle part is greater than that in the ends. Therefore, the design of the cooling pipes 114 in the middle region having a smaller spacing than that at the ends can adapt to the structure of the pier, achieving differentiated heat dissipation, ensuring uniform heat dissipation of the pier as a whole, avoiding temperature stress caused by uneven local heat distribution, and improving the structural strength and service life of the pier.

[0049] In other embodiments, four heat sinks 11 may be provided, and the four heat sinks 11 are arranged in the casting space at 90° intervals around the axis of the casting space.

[0050] Two fixing plates 21 can be spliced ​​and fixed. For example, one of the two fixing plates 21 is provided with a mounting groove that extends vertically and is connected at the top and closed at the bottom. The other fixing plate is provided with a mounting protrusion that slides in the mounting groove to fix the two fixing plates 21.

[0051] In this embodiment, the fixing component 2 further includes fastening bolts 22, and the fixing plate 21 includes a mounting part 211 with mounting holes 2111. The fastening bolts 22 can pass through the mounting holes 2111 of the two fixing plates 21 to fix the two fixing plates 21. The bolt connection is convenient and has high connection strength, and the threaded connection can seal, reducing concrete leakage during concrete pouring.

[0052] Specifically, multiple mounting holes 2111 are arranged vertically at intervals on the mounting part 211, and multiple fastening bolts 22 can be inserted into the multiple mounting holes 2111 one by one. After the two fixing plates 21 are connected, the multiple fastening bolts 22 are evenly stressed, avoiding damage to a single fastening bolt 22 due to excessive stress, and improving the connection stability.

[0053] Specifically, the mounting hole 2111 can be either a threaded hole or a smooth hole. When the mounting hole 2111 is a threaded hole, the fastening bolt 22 can be directly screwed into the mounting hole 2111. When the mounting hole 2111 is a smooth hole, the fastening bolt 22 needs to pass through the mounting holes 2111 of the two fixing plates 21 and be screwed into the existing nuts.

[0054] To improve the support stability of the two fixing plates 21 during concrete pouring, in this embodiment, see... Figure 1The heat dissipation device for the hydration heat of cast-in-place bridge piers also includes a first reinforcing plate 3. The reinforcing plate is arc-shaped and surrounds the convex surface of the fixed plate 21. The arc-shaped first reinforcing plate 3 can disperse the lateral pressure during concrete pouring and improve the stability of the support. Furthermore, it can fit snugly against the fixed plate 21, increasing the contact area, reducing stress, and ensuring the overall strength of the structure.

[0055] Furthermore, the heat dissipation device for the hydration heat of the cast-in-place bridge pier also includes a second reinforcing plate 4. The second reinforcing plate 4 extends vertically, and multiple second reinforcing plates 4 are fixedly connected to the convex surface of the fixing plate 21 at intervals around the axis of the fixing plate 21. The second reinforcing plates 4 pass through the first reinforcing plate 3. The first reinforcing plate 3 and the second reinforcing plate 4, which are arranged in a crisscross pattern, can further improve the pressure resistance of the two fixing plates 21, ensure the stability of the fixing plate 21 during the pouring process, and improve the pouring quality of the pier.

[0056] Specifically, the first reinforcing plate 3 and the second reinforcing plate 4 are also provided with wedge-shaped grooves to facilitate the placement of prefabricated foam boards. The foam boards can reduce the temperature difference between the hydration heat of the pier column and the ambient temperature, and alleviate the cracks caused by temperature stress.

[0057] To more accurately monitor internal issues of the pier, temperature sensors can be installed on the supporting steel bars inside the pier. The flow rate of cooling water can be controlled based on the temperature of the sensors to ensure that the temperature of different parts of the pier is similar, thus preventing cracks caused by temperature differences and improving the strength and service life of the pier.

[0058] Specifically, the main inlet pipe 111 is connected to a water pump, and the flow rate of the cooling water can be adjusted by regulating the pressure of the water pump. To further reduce cooling water retention, the main inlet pipe 111 can be connected to a fan. When the fan is working, a high-speed airflow flows sequentially through the main inlet pipe 111, the sub-inlet pipe 113, the cooling pipe 114, and the main outlet pipe 112. The retained water is dispersed into a mist by the high-speed airflow and discharged with the airflow.

[0059] It is important to understand that the two fixed plates 21 are the casting mold for the pier column. The heat dissipation component 1 is set in the casting space formed by the two fixed plates 21 to transfer the heat of hydration generated by the hydration of the pier column to the outside, thereby reducing the temperature of the pier column. After the temperature of the pier column stabilizes, mortar is poured into the casting space to fill the gaps and ensure the structural strength of the cast pier column.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
