Connecting structure and connecting method for PHC pipe pile and reinforced concrete prefabricated bearing platform
The invention belongs to the technical field of overhead transmission line engineering, and provides a connecting structure and a connecting method of a PHC pipe pile and a reinforced concrete prefabricated bearing platform, the structure comprises the prefabricated bearing platform, a soil-squeezing PHC pipe pile, a connecting cavity, a mechanical connecting piece and a grouting connecting piece; a plurality of connecting cavities are formed in the prefabricated bearing platform, a soil-squeezing type PHC pipe pile is correspondingly arranged in each connecting cavity, and the soil-squeezing type PHC pipe piles form a first-stage connecting structure through mechanical connecting pieces; a reserved space is formed between the inner side wall of the connecting cavity and the soil-squeezing type PHC pipe pile, and a grouting connecting piece is arranged in the reserved space to form a secondary connecting structure. Through the combined action of a first-stage connecting structure formed by the mechanical connecting pieces and a second-stage connecting structure formed by the grouting connecting pieces, the connecting strength and stability between the PHC pipe pile and the reinforced concrete prefabricated bearing platform are remarkably improved. The composite connection mode can more effectively resist various external forces and vibrations, and ensures the safety and durability of the structure.
本发明属于架空输电线路工程技术领域，提供一种PHC管桩与钢筋混凝土预制承台的连接结构及连接方法，所述结构包括预制承台、挤土式PHC管桩、连接空腔、机械连接件和灌浆连接件；若干个连接空腔设置在预制承台内，每个连接空腔的内部均对应设置有挤土式PHC管桩，挤土式PHC管桩通过机械连接件形成一级连接结构；连接空腔内侧壁和挤土式PHC管桩之间有预留空间，预留空间内设置灌浆连接件形成二级连接结构。本发明通过机械连接件形成的一级连接结构和灌浆连接件形成的二级连接结构，共同作用，显著提高了PHC管桩与钢筋混凝土预制承台之间的连接强度和稳定性。这种复合连接方式能够更有效地抵抗各种外力和振动，确保结构的安全性和耐久性。
