Detailed Description

Examples

Referring to fig. 1-4, a reinforcing device for a grouting structure of a high-pressure jet grouting pile comprises a bottom plate 1 and a grouting pipe 2, wherein two limiting columns 3 are fixedly connected to the top end of the bottom plate 1 and are slidably connected with connecting blocks 84, the connecting blocks 84 can be prevented from moving left and right under the action of the limiting columns 3, so that the fixing effect of the reinforcing device on the grouting pipe 2 can be improved, a first screw 5 is screwed in the connecting blocks 84, the function of moving up and down the connecting blocks 84 can be achieved through rotation of the first screw 5, a limiting block 6 is fixedly connected to one of the two limiting columns 3, the first screw 5 passes through the limiting block 6 and is fixedly connected with a handle 7, the limiting block 6 is arranged to prevent the first screw 5 from inclining, the handle 7 is arranged to facilitate rotation of the first screw 5, the two connecting blocks 84 are fixedly connected to the side wall of the connecting blocks 84, a sliding groove 9 is fixedly connected to the side wall of the connecting blocks 84, two sliding grooves 9 are connected with a two clamping blocks 11 are screwed on the two sliding blocks 10, a clamping block 12 is fixedly connected to the side wall of the sliding blocks 11, and the two clamping blocks 12 can be driven to be close to each other or kept away from each other by the two clamping blocks 11 when the sliding blocks 10 rotate, and the two clamping blocks 12 can be driven to be far away from each other or clamped and separated from each other by the clamping pipe 2.
