[0002] Diaphragm walls, as a water-cutting, seepage-proof, load-bearing, and water-retaining structure, have been widely used in urban rail transit construction. Currently, during the construction of diaphragm walls, it is necessary to clean the joints of each trench section.
[0003] Authorization announcement number: CN216689406U discloses a washing device for diaphragm wall joints. The washing device is assembled with a hydraulic grab bucket via a perforated pin. By sliding the hydraulic grab bucket up and down, the washing device removes the deposits inside the I-beam joint. The device can clean the washing surface whether it works from top to bottom or bottom to top, achieving a scraping and brushing process. The washing device cleans the interface twice, doubling the efficiency.
[0004] When this scrubbing device removes deposits from the joints of diaphragm walls, the end of the elastic wire brush that contacts the joint wears out significantly after prolonged use, requiring periodic replacement to maintain its effectiveness. However, the elastic wire brush is bolted to the device, and the presence of multiple bolts on the outside of the device necessitates repeated disassembly and reassembly of these bolts, making the process time-consuming and laborious for the user. This also makes replacing the elastic wire brush inconvenient. Therefore, it is necessary to provide a new scrubbing device for diaphragm wall joints to solve the aforementioned technical problems.

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in Figure 1 A schematic diagram of a preferred embodiment of the device for washing joints of underground continuous walls provided by this utility model; Figure 2 This utility model Figure 1 Enlarged view of point A in the middle; Figure 3 This is a side view of the structure of this utility model; Figure 4 This utility model Figure 3 Enlarged view of point B in the middle; Figure 5 This is a three-dimensional structural view of the present invention. A device for cleaning joints of underground continuous walls includes a device body 1, a flushing pipe 2 connected to one side of the top of the device body 1, a high-pressure nozzle 3 installed on one side of the device body 1, two wire brush blocks 4 installed on the outer side of the device body 1, and a disassembly mechanism installed on the outer side of the device body 1 for disassembling and replacing the wire brush blocks 4. The disassembly mechanism includes a U-shaped frame 101, a storage groove 102 inside the U-shaped frame 101, and a pressing plate 103 installed inside the storage groove 102. The top of the pressing plate 103... A pressing rod 104 is fixedly provided. The top end of the pressing rod 104 is inserted into the insertion hole 105 opened inside the U-shaped frame 101.

The pressing plate 106 drives the pressing rod 104 and the pressing plate 103 to move downward, so that the pressing plate 103 presses the fixing rod 110 in the fixing hole 401 and presses the fixing rod 110 into the groove 107. Then the wire brush block 4 can be pulled to one side to remove the wire brush block 4 from the device body 1, making the removal of the wire brush block 4 time-saving and labor-saving. Then, insert one end of the new wire brush block 4 into the U-shaped frame 101, so that the fixing rod 110 in the groove 107 moves into the fixing hole 401 under the elastic action of the spring 108. Through the cooperation of the fixing rod 110 and the fixing hole 401, the wire brush block 4 can be fixed on the device body 1, so that the new wire brush block 4 can be used normally on the device body 1.

The reinforcing block 113 can fix the strip block 112 to the device body 1 together, making the strip block 112 more secure and reliable on one side of the device body 1.
[0029] Reference Figure 1 , Figure 3 and Figure 4 A drive motor 114 is fixed to one side of the bottom of the strip block 112. A transmission shaft 115 is fixedly connected to the output end of the drive motor 114. A chamber 116 is opened inside the strip block 112. A gear 117 is provided on the outside of the transmission shaft 115 extending to the outside of the chamber 116. A gear 118 meshes with one side of the gear 117. A lead screw 119 is fixed on the gear 118. A threaded sleeve 120 is sleeved on the outside of the lead screw 119. A transmission block 121 is fixed to the top of the threaded sleeve 120. The top of the transmission block 121 is... A through-strip block 112 is fixedly connected to the bottom of the high-pressure nozzle 3. The drive motor 114 drives the transmission shaft 115 and gear 117 to rotate. Gear 117 drives gear 118 and lead screw 119 to rotate. Lead screw 119 drives threaded sleeve 120 to rotate. The cooperation between lead screw 119 and threaded sleeve 120 causes threaded sleeve 120 to drive transmission block 121 and high-pressure nozzle 3 to adjust left and right, so as to improve the flushing effect of high-pressure nozzle 3 on the underground continuous wall joint.
[0030] Reference Figure 3 and Figure 4A baffle 122 is sleeved on the outside of the lead screw 119. The baffle 122 limits the movement of the lead sleeve 120. The outside of the baffle 122 is fixedly connected to the inner wall of the chamber 116. The baffle 122 limits the movement of the lead sleeve 120 to prevent the lead sleeve 120 from colliding with the gear 118 when it moves, so that the lead sleeve 120 and the gear 118 can be used normally in the chamber 116.
[0031] Reference Figure 3 and Figure 4 A guide rod 123 is inserted into the threaded sleeve 120. One end of the guide rod 123 is fixedly connected to one side of the baffle 122, and the other end of the guide rod 123 is fixedly connected to the inner wall of the chamber 116. By setting the guide rod 123, the threaded sleeve 120 can move normally left and right in the chamber 116 to prevent the threaded sleeve 120 from rotating in the chamber 116.

When the high-pressure nozzle 3 is adjusted left and right, the slider 302 on its top slides left and right on the sliding rod 303. Through the cooperation of the slider 302 and the sliding rod 303, the adjustment of the high-pressure nozzle 3 is more stable.
[0033] The implementation principle of the device for cleaning the joint of a diaphragm wall according to this utility model embodiment is as follows: By using a disassembly mechanism, the pressing plate 106 is pressed down, and the pressing plate 106 drives the extrusion rod 104 and the extrusion plate 103 to move downward, so that the extrusion plate 103 extrudes the fixing rod 110 in the fixing hole 401 and extrudes the fixing rod 110 into the groove 107. Then, the wire brush block 4 can be pulled to one side, and the wire brush block 4 can be removed from the device body 1, making the removal of the wire brush block 4 time-saving and labor-saving. Then, one end of the new wire brush block 4 is inserted into the U-shaped frame 101, so that the fixing rod 110 in the groove 107 moves into the fixing hole 401 under the elastic action of the spring 108. Through the cooperation of the fixing rod 110 and the fixing hole 401, the wire brush block 4 can be fixed on the device body 1, so that the new wire brush block 4 can be used normally on the device body 1.
