Guangdong Construction Engineering obtains utility model patent authorization: "A construction structure for PHC pipe piles on steep hillside rocky foundations"

Securities Star News, according to Tianyancha APP data, Guangdong Construction Engineering Group Co., Ltd. (002060) has recently been granted a new utility model patent. The patent is titled “Construction Structure of PHC Pipe Piles on Steep Mountain Slopes with Rocky Foundations,” with application number CN202520569115.6, and it was authorized on March 27, 2026.

Patent Abstract: This utility model belongs to the field of PHC pipe pile construction technology, specifically involving a construction structure for PHC pipe piles on rocky foundations of steep mountain slopes. It includes pile holes, reinforcement cages, and PHC pipe piles; the bottom of the PHC pipe pile is equipped with an end plate, and the main reinforcement of the reinforcement cage is welded to the end plate. The reinforcement cage is set at the bottom of the pile hole, with a length equal to one-third of the pile hole’s length. The section of the pile hole at the depth of the reinforcement cage is filled with solid concrete, while the section above the reinforcement cage contains the PHC pipe pile. The diameter of the pile hole matches the diameter of the PHC pipe pile. The upper part uses PHC pipe piles, and the lower part uses cast-in-place concrete piles, meeting bending resistance requirements. Additionally, the uplift resistance of the cast-in-place pile can offset the insufficient uplift resistance of the PHC pipe pile caused by the drilling process.
