Description

Technical Field

[0001] The utility model relates to the technical field of long-span bridge construction, in particular to a three-dimensionally cooled U-shaped concrete cap. Background Art

[0002] A three-dimensionally cooled U-shaped concrete cap is mainly used in the construction process of large concrete structures, especially in situations where it is necessary to control the heat of concrete hydration and prevent concrete cracking. After concrete pouring, the cement hydration reaction will generate a large amount of heat, causing the temperature inside the concrete to rise. The three-dimensional cooling system helps to quickly disperse the heat inside the concrete to prevent overheating. By using the three-dimensional cooling system, this temperature difference can be reduced, thereby reducing the risk of cracking. The three-dimensionally cooled U-shaped concrete cap is an advanced concrete construction technology. It provides higher quality and reliability for concrete construction through a well-designed cooling system.

[0003] At present, the commonly used cooling measure for the cap is to arrange cooling pipes to build a cooling system. The existing cooling system for the construction of concrete caps is arranged with multiple water pumps and water storage tanks. Before pouring concrete, some cooling water pipes are pre-buried inside the cap to reduce the temperature inside the concrete by circulating cold water. A spray system is used to spray water mist on the concrete surface to reduce the temperature of the concrete surface through evaporative cooling. Cooling water pipes are arranged on the concrete surface to reduce the temperature of the concrete surface through circulating cold water.

[0004] The existing cooling system for foundation construction cannot realize a multi-valve circulation cooling system. The arrangement of cooling pipes in traditional cooling methods often results in the cooling pipes being laid too long in the concrete, causing water flow to be blocked or stagnant in certain areas for a long time, affecting the normal operation of the cooling system. In addition, the arrangement of the water inlet and outlet of the existing cooling system causes uneven distribution of water flow inside the foundation, causing some areas to overheat and other areas to be too cold, thereby inducing thermal stress and causing deformation or cracking of the foundation structure. Utility Model Content

In addition, the arrangement of the water inlet and outlet of the existing cooling system causes the water flow to be unevenly distributed inside the pedestal, thereby inducing thermal stress and causing the technical problem of deformation or cracking of the pedestal structure.
