Description

Technical Field

[0001] This utility model relates to the technical field of wall brushing devices for trenching machines, specifically a wall brushing device for a trenching machine for underground continuous walls. Background Technology

[0002] During the construction of diaphragm walls, especially when using slurry wall protection technology, a layer of mud cake forms on the trench wall. Wall brushing effectively removes these deposits, ensuring a good bond between the newly poured concrete and the completed wall or adjacent trench sections, preventing "mud inclusion." By removing interface impurities, potential leakage channels are reduced, improving the overall seepage prevention capability of the diaphragm wall. Cleaning the interface allows for better bonding between the old and new concrete, forming a unified load-bearing structure. For example, a diaphragm wall brushing device disclosed in Chinese patent literature (application number: CN2)... In 02021857662.8, the wall brush body is connected and fixed by a simple suspension device to perform wall brushing work on the diaphragm wall. The wall brush body and the suspension device move up and down or left and right back and forth. Wall brushing work on the diaphragm wall requires manual operation or segmented control. The brushing speed is slow and may prolong the construction period (especially for ultra-deep trench sections). The coverage rate depends on the operator's experience and there may be missed areas. After long-term use, the wire brush on the wall brush will wear out and need to be replaced in time. The wall brush body of the above-mentioned patent cannot be replaced quickly.

[0003] Therefore, we propose a wall-brushing device for a diaphragm wall trenching machine. Utility Model Content

By rotating the brush head, a large area of ​​the trench wall is covered, and cleaning can be completed in a single operation, shortening the construction period. It is suitable for standardized trench sections (such as rectangular trenches), and is especially suitable for large-scale underground projects. When the brush plate 1 is replaced, it is pulled... The lever 16 pulls the locking block 15 to move, and the locking block 15 disengages from the slot 51, releasing the fixing of the mounting shaft 5. The brush plate 1 is then moved to quickly disassemble it. The mounting shaft 5 on the new brush plate 1 is passed through the second through hole 61 set in the middle of the fixed housing 3 and the driven gear 6.
