REINFORCING AND LIFTING METHOD AND REINFORCING AND LIFTING STRUCTURE FOR LARGE-SCALE PIERS OF HIGH-SPEED RAIL
Disclosed are a reinforcing and lifting method and a reinforcing and lifting structure for large-scale piers of high-speed rail. The method comprises: obliquely drilling grouting holes for a pile shoe body downward around the bridge pier cap, the hole bottom goes deep into a pile foundation side position close to the bottom end of the bridge pier pile foundation, grouting the hole bottom, and reinforcing the soil body between a plurality of pile foundations and around the pile foundations to form the pile shoe body; vertically drilling holes downward around the bridge pier cap to form a plurality of curtain holes at intervals, and grouting the curtain holes to form an enclosed curtain wall, the curtain wall and the pile shoe body form an inverted groove structure; obliquely drilling holes downward to form lifting holes, such that the bridge piers are gradually raised to a preset height.
