摘要： 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.

摘要： The present application relates to a precise lifting method and a lifting and reinforcing structure for a plant equipment foundation. The method includes the construction steps of: forming a curtain wall: drilling downwards at two sides of the plant equipment to form curtain holes and grouting the curtain holes, in which the grouting areas overlap each other to form two parallel curtain walls; forming a reinforcing body: drilling grouting holes inclining downwards, grouting the grouting holes to form the reinforcing body attached to a lower surface of a baseplate of the plant equipment foundation among a bottom of the baseplate and two curtain walls; and lifting: drilling lifting holes obliquely downwards to below the bottom of the reinforcing body and between two curtain walls; and conducting pressure grouting to the bottom of the lifting holes and then backward grouting upwards layer by layer.

摘要： Provided are a pile foundation bearing platform settlement, reinforcement, lift-up and leveling structure and a construction method thereof. The structure includes a bearing platform and a plurality of pile foundations, a weak soil reinforcement layer under the bearing platform and a pile tip bearing stratum. The weak soil reinforcement layer forms a plurality of first grouting holes, and the first grouting hole extends through the bearing platform and communicates with the outside. The first grouting hole is used to perform primary grouting in the weak soil reinforcement layer. The pile tip bearing stratum forms a plurality of second grouting holes, and the second grouting hole extends through the weak soil reinforcement layer and the bearing platform, and communicates with the outside. The second grouting hole is used to perform secondary grouting in the pile tip bearing stratum.
