[0002] As one of deep foundation pit engineering support structures, the joint of underground continuous wall often has problems such as mud sand entrainment, joint water seepage and complicated construction process.

[0003] The sleeve milling joint process directly cuts the concrete of the formed groove section by using a groove milling machine, and forms the underground continuous wall joint with good water stop and density. This process not only reduces the mud sand at the joint to the minimum, but also combines the concrete of adjacent groove sections well, and has better water tightness. However, the sleeve milling joint process also needs to perform wall brushing operation on the concrete of the formed groove section to remove the dirt such as mud skin on the surface of the concrete, so as to ensure the cleanliness and water tightness of the joint.

It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0034] Please refer to Figures 1 to 5 The sleeve milling joint wall brushing device is described. A sleeve milling joint wall brushing device comprises a driving system 10 and a cleaning system. The driving system 10 has a driving piece with a rotating shaft, and the central axis of the rotating shaft is parallel to the vertical direction. The cleaning system has a plurality of cleaning pieces 20 connected with the rotating shaft and a reciprocating unit 30. The reciprocating unit 30 has a pressing piece and an elastic piece 301 arranged on the upper and lower sides of the cleaning piece 20 respectively. The pressing piece is used to press the cleaning piece 20 downward, and the elastic piece 301 has a pre-tightening force to make the cleaning piece 20 move upward.

[0035] Specifically, the driving system 10 further comprises a connecting piece 101, the driving piece is a rotary drilling machine and is not shown in the figure, the connecting piece 101 is a discarded drill barrel, and the cleaning piece 20 is a waste steel wire.

[0036] It should be noted that the axial direction of the rotating shaft is the up-down direction.

[0037] Compared with the prior art, the sleeve milling joint wall brushing device provided in the embodiment has the following advantages:

[0038] During the wall brushing process, the driving system 10 makes the cleaning piece 20 rotate, and at the same time, the reciprocating unit 30 makes the cleaning piece 20 move up and down reciprocally. Therefore, the cleaning piece 20 can not only rotate but also swing up and down, thereby improving the cleaning effect.

[0039] In some examples, referring to Figures 1 to 4 The cleaning system further comprises a base plate 40 fixed to the outer periphery of the rotating shaft. The base plate 40 is provided with an adjusting seat 401 corresponding to the cleaning piece 20 on the side away from the rotating shaft. The adjusting seat 401 is provided with an adjusting cavity 4011 on the side away from the base plate 40.

[0040] The reciprocating unit 30 is arranged in the adjusting cavity 4011. The adjusting cavity 4011 is provided with a mounting seat 402 for fixing the cleaning piece 20. The pressing piece is located above the mounting seat 402, and the elastic piece 301 is fixed between the bottom of the mounting seat 402 and the inner wall of the adjusting cavity 4011.
