[0002] In modern construction projects, concrete structures are widely used in various types of buildings, including residential buildings, public facilities, industrial facilities, etc. Among them, prestressed reinforced pile-slab walls are a common structural element, usually used for foundation support and wall structures. In traditional construction models, concrete structural elements are usually cast on site. This method involves mixing concrete on the construction site and then pouring the concrete into the formwork to form the required structural elements.

[0003] On-site concrete pouring has a great impact on the environment because it requires a lot of water and electricity, and also produces a lot of waste.

In addition, although integral concrete pouring can achieve structural continuity, it lacks sufficient flexibility to adapt to different design requirements and construction conditions. In the application of prefabricated pile panels, due to the lack of effective connection structure, the connection between these pile panels is usually not prestressed, so its performance in resisting natural disasters such as earthquakes and storms is relatively poor. This limitation greatly limits the scope of prefabricated pile panels in practical applications, especially in situations where high strength and durability are required. Utility Model Content
