Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wall brushes, in particular to a targeted wall brush for underground continuous walls. Background Art
[0002] During the construction of underground continuous walls of subway station enclosure structures, wall joint treatment is a very critical process. The quality of the treatment directly affects the water leakage of the wall joints during the excavation of the foundation pit. In order to ensure a tight fit between the two walls, a wall brush is required to thoroughly remove the mud on the surface of the I-beam and the flowing concrete and other debris, especially the concrete within a certain depth range, which needs to be repeatedly scraped and cleaned.
[0003] The traditional "crane wall brush" is installed on an ordinary crane, connected to the brush head by a steel wire rope, and repeatedly lifted and lowered to remove debris such as mud on the surface of the I-beam and circling concrete. However, the installation and construction of the traditional "crane wall brush" are relatively cumbersome, time-consuming and labor-intensive. The suspended wall brush is prone to sliding along the layer, resulting in poor wall brushing effect and difficult verticality control. Therefore, a hanging wall brush has appeared in the prior art. The hanging wall brush is hung on the side wall of the trenching machine bucket. It is easy to install, easy to control, not easy to slide, and easy to clean the underground continuous wall in a directional manner, with a good wall brushing effect. The hanging wall brush usually includes a mounting plate, which is installed on the side walls on both sides of the trenching machine bucket, and a steel brush is installed on the outside of the mounting plate.
[0004] However, the steel brushes on the existing hanging wall brushes are usually arranged perpendicular to the mounting plate. When the hanging wall brushes move up and down, the steel brushes will tilt along the moving direction under the squeeze, and it takes many times to brush off the stubborn concrete adhering to the surface of the I-beam, which is inefficient. Utility Model Content
[0005] In order to solve the technical problem that the steel brushes on the existing hanging wall brushes are usually arranged perpendicular to the mounting plate, and when the hanging wall brushes move up and down, the steel brushes will tilt along the moving direction under squeezing, and it is necessary to repeatedly brush off the stubborn concrete adhering to the surface of the I-beam, resulting in low efficiency, the utility model provides a targeted wall brush for underground continuous walls.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

Since the inclination directions of the first steel wire clusters in two adjacent rows are opposite, when the trenching machine bucket drives the mounting plate to move back and forth in the inclination direction of the first steel wire clusters to scrub the underground continuous wall, the first steel wire clusters with different inclination directions can continuously scrub the wall surface of the underground continuous wall, with greater scrubbing force and higher scrubbing efficiency.
[0009] As a preferred implementation of a targeted wall brush for an underground continuous wall, the wire brush also includes a plurality of parallel rows of second steel wire clusters, each row of the second steel wire clusters is tilted, and the tilt directions of two adjacent rows of the second steel wire clusters are opposite.

[0011] As a preferred implementation of a targeted wall brush for an underground continuous wall, the first steel wire cluster is inclined in the upper and lower directions of the mounting plate, and the second steel wire cluster is inclined in the left and right directions of the mounting plate.
[0012] With the above structural solution, since the first steel wire clusters are inclined in the upper and lower directions of the mounting plate, the inclined directions of the first steel wire clusters in two adjacent rows are opposite, when the trenching machine bucket drives the mounting plate to move up and down to brush the underground continuous wall, the first steel wire clusters inclined up and down continuously brush the wall surface of the underground continuous wall up and down, with greater brushing force and higher brushing efficiency. Since the second steel wire clusters are inclined in the left and right directions of the mounting plate, the inclined directions of the second steel wire clusters in two adjacent rows are opposite, when the trenching machine bucket drives the mounting plate to move left and right to brush the underground continuous wall, the second steel wire clusters inclined left and right continuously brush the wall surface of the underground continuous wall left and right, with greater brushing force and higher brushing efficiency.
[0013] As a preferred implementation of a targeted wall brush for an underground continuous wall, the thickness of the mounting plate is 20 mm.
[0014] As a preferred implementation of a targeted wall brush for an underground continuous wall, a mounting plate is connected to the wire brush by welding.
[0015] By adopting the above structural solution, the connection strength between the mounting plate and the wire brush is high, and the wire brush is not easy to fall off.
[0016] As a preferred implementation of a targeted wall brush for an underground continuous wall, the mounting plate is mounted on the side wall of a trenching machine bucket.
[0017] As a preferred implementation of a targeted wall brush for an underground continuous wall, two lifting ears are installed on the upper side of the mounting plate.
[0018] The above structural solution is adopted to facilitate the hanging and installation of the installation plate.
[0019] As a preferred implementation of a targeted wall brush for an underground continuous wall, the mounting plate is connected to the lifting ear by welding.
