Description

Technical Field

[0001] The invention relates to a concrete anti-cracking structure for a multi-elevation basement super-long structure. Background Art

[0002] During the concrete construction process, the cement hydration reaction releases a large amount of heat, and the thermal conductivity of concrete is relatively poor, which will cause the temperature inside the concrete to rise rapidly, while the external temperature is relatively low. This temperature difference between the inside and outside will produce temperature stress inside the concrete. When the temperature stress exceeds the tensile limit of the concrete, cracks will appear in the concrete. These cracks not only affect the appearance quality of the concrete structure, but also threaten its integrity and durability, and thus pose a potential risk to the safety and normal use of the structure. There is a method of pre-embedding cooling water pipes in the steel skeleton to reduce the temperature difference between the inside and outside of the concrete after pouring. However, the pre-embedded cooling water pipes are tied with steel wires. During the concrete pouring and vibration process, due to the fluidity and vibration force of the concrete, the fixing points of the steel wires may be impacted and loosened. Once the fixing is unstable, the cooling water pipes may shift or deform, thereby affecting their cooling effect. Summary of the invention
