Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a reinforcement cage protective layer pad. Background Art

[0002] With the rapid development of my country's economy, transportation modes such as railways and urban rail transit have been greatly improved and expanded. Against this background, the construction of major infrastructure such as cross-sea bridges is also increasing. These cross-sea bridges usually use super-long and long-diameter pile foundations as the lower bearing foundation to ensure the stability and safety of the structure. However, the high concentration of chloride ions in the marine environment has a serious problem of corrosion of steel bars, which poses a huge challenge to the protection of pile foundation steel bars. In order to prevent the corrosion of pile foundation steel bars by chloride ions in the marine environment, a thicker steel bar protective layer is usually designed. However, how to effectively control the thickness of the protective layer and ensure its uniformity and stability is an important technical problem in construction. The protective layer pads on the market currently have problems such as low installation accuracy, inconvenient operation, high construction difficulty, and low construction efficiency, which not only affects the construction progress, but also reduces the quality and safety of the project. Therefore, it is particularly important to develop a steel cage protective layer pad that is easy to install, has low construction difficulty, and is highly efficient. This new type of pad should have the following innovative features: first, the structural design of the pad should ensure that it can be easily fixed on the steel cage during installation, reducing the complexity and labor intensity of workers' operations; second, the pad should have high-precision size control capabilities to ensure the uniformity and stability of the thickness of the protective layer; finally, the pad material should have good durability and corrosion resistance to adapt to the long-term impact of the harsh marine environment. Summary of the invention
