For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0022] Please refer to the attached Figure 1 To Attachment Figure 2 The utility model describes a conductor frame pile leg grouting and plugging device.

[0023] The existing method of grouting reinforcement for the pile leg 6 without the packer installed is to throw sand into the steel pile 5 or use sandbags or quilts to block the outside of the root of the pile leg 6, but the blocking effect is poor and there is a risk of leakage.

[0024] Therefore, if Figure 1 and Figure 2 As shown, the utility model provides a grouting and sealing device for a conductor frame pile leg, including a bottom sealing ring 1, which is sleeved on a steel pile 5 so that the bottom sealing ring 1 abuts against the steel pile 5 to seal the gap between the bottom sealing ring 1 and the steel pile 5, and a lateral sealing plate 2 is fixedly connected to the bottom sealing ring 1, and the lateral sealing plate 2 is sleeved on the pile leg 6 so that the lateral sealing plate 2 abuts against the pile leg 6 to seal the gap between the lateral sealing plate 2 and the pile leg 6.

[0025] The bottom blocking ring 1 is provided with a first abutting surface 101 , through which the bottom blocking ring 1 abuts against the steel pile 5 ; the lateral blocking plate 2 is provided with a second abutting surface 201 , through which the lateral blocking plate 2 abuts against the pile leg 6 .

[0026] Preferably, a rubber layer is provided on the first abutting surface 101 and the second abutting surface 201 to further improve the sealing between the bottom sealing ring 1 and the steel pile 5, and between the lateral sealing plate 2 and the pile leg 6. At the same time, the rubber layer can be replaced by other sealing materials well known to technicians in this field, such as plastic, hair spray, etc.

[0027] A sealing layer 3 is provided on the bottom sealing ring 1, and the sealing layer 3 is respectively in contact with the steel pile 5 and the pile leg 6 to improve the sealing performance of the device and reduce the risk of leakage. The material used for the sealing layer 3 can be rubber, plastic, hair spray or other sealing fillers familiar to those skilled in the art.

The inlet end of the grouting port 4 is connected to the slurry pipe 7, and the outlet end of the grouting port 4 extends away from the inlet end. The height of the outlet end of the grouting port 4 is higher than the height of the sealing layer 3, that is, the outlet end of the grouting port 4 passes over the sealing layer 3 to ensure the sealing performance of the sealing layer 3 and avoid the sealing filler of the sealing layer 3 being washed away by cement sprayed from the outlet end of the grouting port 4 during grouting.

[0029] The bottom sealing ring 1 includes a first semicircular ring 100 and a second semicircular ring 200.

By fixing the first splicing plate 300 and the second splicing plate 400, the first semicircular ring 100 and the second semicircular ring 200 are spliced ​​into a bottom sealing ring 1.

[0031] Through holes are provided on the first splicing plate 300 and the second splicing plate 400. Bolts pass through the through holes of the first splicing plate 300 and the through holes of the second splicing plate 400 and are screwed to nuts. The nuts are tightened to fix the first splicing plate 300 and the second splicing plate 400.
