Description

Technical Field

[0001] The present application relates to the field of construction technology, and in particular to a new type of large-volume concrete water circulation cooling temperature control device for an arch seat. Background Art

[0002] The arch seat is a special structure in large bridge projects. Its main function is to connect the arch ring and the pier, and bear the load from the arch superstructure. It is a very important load-bearing member in large bridge structures. Due to the large volume of the main arch seat structure, large-volume concrete construction technology is required. After the concrete is poured, a large amount of hydration heat will be released. How to effectively deal with the hydration heat and reduce the temperature difference between the concrete structure inside and outside the main arch seat is the key and difficult point of the main arch seat construction. At present, there are many technical means to control the occurrence of concrete cracks in engineering construction, among which water cooling technology is the most effective. Traditional water cooling technology arranges multiple circulating cooling water pipes in the concrete, and injects cooling water into each circulating cooling water pipe to achieve cooling of the concrete.

[0003] However, when installing the existing circulating cooling water pipelines, it is not convenient to adjust the distance between the circulating cooling water pipelines, thereby affecting the installation efficiency of the circulating cooling water pipelines and reducing the practicability of the device.

[0004] Traditional water cooling technology arranges multiple circulating cooling water pipes in the concrete. When cooling water is injected into each circulating cooling water pipe separately, the injection efficiency is low and it is easy to cause uneven temperature inside the concrete.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0009] Preferably, the limiting assembly includes connecting pipes symmetrically installed on the side walls of two adjacent cooling steel pipes close to each other, and the outer sides of the close ends of the two connecting pipes on the same side are slidably connected with connecting sleeves.
