Underwater rock-socketed concrete pile for hydraulic engineering and construction method thereof
The invention relates to the technical field of rock-socketed concrete piles, and provides an underwater rock-socketed concrete pile for a water conservancy project, the underwater rock-socketed concrete pile comprises a steel pipe pile, a first precast concrete pile and a second precast concrete pile, the lower end of the steel pipe pile is inserted into the top surface of bedrock, and the first precast concrete pile is located in a bedrock hole; the diameter of the first precast concrete pile is smaller than that of the bedrock hole, the second precast concrete pile is located in the steel pipe pile, the first precast concrete pile and the inner wall of the bedrock hole are connected into a whole through a first concrete layer, and the first precast concrete pile and the second precast concrete pile are connected into a whole through a second concrete layer. The first concrete layer and the inner wall of the lower end of the steel pipe pile are connected into a whole, and the second prefabricated concrete pile and the steel pipe pile are connected into a whole through the second concrete layer. Therefore, the construction efficiency can be improved. In addition, the invention further provides a construction method of the underwater rock-socketed concrete pile for the water conservancy project.
本申请涉及嵌岩混凝土桩技术领域，提供了一种水利工程用水下嵌岩混凝土桩，包括钢管桩、第一预制混凝土桩和第二预制混凝土桩，所述钢管桩下端插至基岩顶面，所述第一预制混凝土桩位于基岩孔内，且所述第一预制混凝土桩的直径小于所述基岩孔的直径，所述第二预制混凝土桩位于所述钢管桩内，所述第一预制混凝土桩与所述基岩孔内壁之间和所述第一预制混凝土桩与所述第二预制混凝土桩之间通过第一混凝土层连接为一体，且所述第一混凝土层与所述钢管桩下端的内壁连接为一体，所述第二预制混凝土桩与所述钢管桩通过第二混凝土层连接为一体。基于此，可提高施工效率。此外，还提供了一种水利工程用水下嵌岩混凝土桩的施工方法。
