DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 4 As shown, the present invention provides a method for cleaning the joint surface of an underground continuous wall, comprising the following steps:

[0027] Step 1: Determine the continuous wall joint surface area that needs to be cleaned;

[0028] Step 2: Arrange a wall brushing box 1 above the ground in the continuous wall joint surface area;

[0029] Step 3: Adjust the position of the wall brush box 1 on the adjustment frame 3 and the height of the wall brush box 1 itself;

[0030] Step 4: Adjust the angle of the brush roller 5 so that the brush roller 5 and the joint surface fit each other;

[0031] Step 5, open the brush roller 5 to clean the joint surface, and move the brush roller 5 up and down;

[0032] Step 6: After cleaning, remove the wall brush box 1.

[0033] The wall brushing box 1 is a square box as a whole, and a square pedestal 11 is arranged at the lower part of the wall brushing box 1 . An adjusting plate 4 is installed at the lower part of the pedestal 11 , and the wall brushing roller 5 is arranged at the lower part of the adjusting plate 4 .

[0034] The movement of the wall brush roller 5 is driven by the movement of the adjusting plate 4, so that the wall brush roller 5 can be adjusted up and down to clean the joint surface during the cleaning operation.

[0035] The two ends of the lower part of the pedestal 11 are provided with sleeves 12 in parallel, and the adjustment plate 4 is provided with two adjustment rods 41 correspondingly. The adjustment rods 41 are docked in the sleeves 12 and connected to the electric push rods in the sleeves 12 .

[0036] The sleeve 12 and the adjusting rod 41 are nested with each other and driven by an electric push rod, so that the height of the adjusting plate 4 can be adjusted conveniently.

[0037] Among them, two groups of rotating seats 42 are arranged at the lower part of the adjustment plate 4, and a rotating frame 43 is installed on the inner side of the rotating seat 42, and the brush wall roller 5 is arranged between the two groups of rotating frames 43; the rotating frame 43 is driven by a rotating motor embedded in the rotating seat 42, and the brush wall roller 5 is driven by a servo motor embedded in the rotating frame 43.

[0038] The rotating seat 42 and the rotating frame 43 can rotate relative to each other, so that the brush roller 5 installed at the other end of the rotating frame 43 can rotate in a plane, making it close to or away from the joint surface, adjusting the degree of fit between it and the joint surface, and facilitating the control of the degree of cleaning work.

[0039] Among them, a slider 2 is arranged on the upper part of the adjustment frame 3, and multiple sliders 2 are arranged side by side, wherein a moving seat 21 is arranged on the middle slider 2, and a sleeve 23 is arranged on the moving seat 21; supports 13 are arranged on both sides of the wall brushing box 1, and a lifting rod 14 is arranged at the lower part of the support 13, and the lifting rod 14 is docked in the sleeve 23 and connected to the cylinder output end in the sleeve 23.

[0040] The sleeve 23 and the lifting rod 14 are nested and can move up and down, so as to adjust the height of the wall brushing box 1, thereby achieving the effect of adjusting its position as a whole. The height can be adjusted in conjunction with the sleeve 12 and the adjusting rod 41, which makes it more convenient and efficient to use.

[0041] Among them, three sliders 2 are arranged side by side, among which a moving seat 21 is arranged on the middle slider 2, and stable seats 22 are arranged on the upper parts of the other two sliders 2; the stable seats 22 are symmetrically arranged on both sides of the moving seat 21, and an inclined reinforcing rod 24 is arranged between the stable seat 22 and the sleeve 23.

[0042] The provision of the stabilizing seat 22 can increase the stability of the sleeve 23 provided on the upper portion of the slider 2, thereby ensuring the stability of the overall arrangement.

[0043] A T-shaped limiting belt 31 is disposed on the upper portion of the adjusting frame 3 , and a limiting groove 25 is disposed on the lower portion of the sliding block 2 . The limiting groove 25 is engaged with and clamped on the limiting belt 31 .

[0044] The limiting groove 25 and the limiting belt 31 are engaged with each other, so that the slider 2 can move in a constant direction to avoid deviation.

[0045] The wall brush roller 5 is externally covered with a cleaning brush sleeve 51 , and the cleaning brush sleeve 51 is entirely wrapped with a steel wire brush.

[0046] The wire brush wraps around the brush roller 5 to form a cleaning brush sleeve 51 which is in direct contact with the joint surface during use, thereby achieving a cleaning effect.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
