Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment for anti-seepage wall construction, and in particular to a wall brush for anti-seepage wall joints. Background Technology

[0002] The construction of underground concrete cutoff walls in water conservancy projects is generally divided into several sections, each individually trenched and constructed using trenching equipment. Joint pipes are typically embedded between sections to form arc-shaped joints that extend the seepage path. During phased trenching and pouring, the use of mud slurry for wall protection during trenching and drilling of later-pouring sections can easily form mud cake on the joint concrete of earlier-pouring sections, affecting joint quality. After the cutoff wall is completed, the downstream water level drops, and the mud trapped in the joints loses water and shrinks, creating voids within the joints and forming seepage channels, thus affecting the seepage prevention effect. Therefore, it is necessary to clean the mud cake adhering to the joint concrete. Traditional cleaning methods typically involve welding or bolting a brush-like scrubbing device to the grab bucket of the trenching machine, using the grab bucket's up-and-down movement to clean the mud cake from the joints.

[0003] The drawbacks of traditional scrubbing devices are:

[0004] (1) The manufacturing and installation process is complex and requires highly skilled cutting and welding technicians to operate;

[0005] (2) The brushing device is a straight plate type, which is difficult to fit with the common arc-shaped groove joint, resulting in poor brushing effect.

[0006] Therefore, there is an urgent need for a new type of waterproof wall joint brushing device. Utility Model Content

[0007] The main purpose of this utility model is to provide a wall brush for a waterproof wall joint, so as to solve the problems of complex manufacturing and poor adhesion to the arc-shaped groove joint in the prior art, resulting in poor brushing effect.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] According to the present application, a wall-brushing device for a seepage-proof wall joint includes a main body, the main body including a curved wall and an inner cavity defined by the curved wall, the inner cavity being open at at least one end along the axial direction of the main body, the main body being provided with a plurality of spaced mounting holes, a steel wire bundle being snapped into the mounting holes, the inner cavity being filled with concrete, the concrete being fixedly connected to the inner wall of the main body and the portion of the steel wire bundle located in the inner cavity by pouring.

[0010] According to the seepage-proof wall joint brushing device of this application, the wire bundle includes a plurality of steel wires gathered together.

[0011] According to the anti-seepage wall joint brushing device of this application, a plurality of mounting holes are arranged in a quincunx pattern. The plurality of mounting holes are divided into first mounting holes and second mounting holes. The quincunx pattern includes a plurality of first units arranged in rows in a first direction and columns in a second direction. The first unit includes a first mounting hole located at the center and a plurality of second mounting holes arranged around the first mounting hole. Two adjacent first units share the same row of second mounting holes. In the direction of the rows, two adjacent first units share the same column of second mounting holes. The first direction is perpendicular to the second direction and parallel to the axial direction of the main body. The second direction extends circumferentially along the main body.

[0012] Optionally, each of the first units includes four second mounting holes, and in the direction of the row, the central angle between two adjacent second mounting holes in the same first unit is 30° to 90°.

[0013] According to the anti-seepage wall joint brushing device of this application, the main body is cylindrical, and the free ends of the steel wire bundle are distributed on the cylindrical surface of the same diameter.

[0014] According to the anti-seepage wall joint brushing device of this application, the main body is also provided with two opposite snap-fit ​​holes, the two snap-fit ​​holes are at different heights in the axial direction of the main body, and a hanging ring is also provided in the inner cavity. The hanging ring is bent into an inverted U-shape, and the two free ends of the hanging ring are bent into L-shapes and staggered into the snap-fit ​​holes opposite to the free ends. The concrete is fixedly connected to the hanging ring by pouring.

[0015] Optionally, the diameter of the hanging ring is larger than the diameter of the wire bundle.

[0016] Optionally, the hanging ring is engaged with the wire bundle.

[0017] The technical solution provided by the utility model embodiments has the following advantages compared with the prior art:

[0018] The wall brush for seepage-proof wall joints provided by this utility model has a curved wall with a fixed curvature, which can be adapted to the curvature of the arc-shaped joint of the seepage-proof wall to be cleaned, thereby improving the compatibility between the main body and the arc-shaped joint of the seepage-proof wall. This ensures that the brush maintains uniform contact pressure during the brushing process, ensuring that the steel wire bundle adheres to the joint surface and avoiding blind spots in localized cleaning caused by curvature mismatch in traditional flat brushes. The mounting holes interlock with the steel wire bundle to form a flexible brush body, ensuring uniform removal of mud skin. The inner cavity is filled with concrete to form a rigid whole with the shell, and its own weight increases the brushing pressure. At the same time, the concrete pouring fixes the steel wire bundle and the main structure, improving the stability of the device. The overall structure does not require complex connecting parts, the manufacturing process is simple, and the on-site processing difficulty and cost are reduced, making it suitable for efficient wall brushing operations in different construction environments.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] like Figures 1-3 As shown, the wall brushing device for the anti-seepage wall joint according to an embodiment of this application includes a main body 10. The main body 10 includes a curved wall and an inner cavity defined by the curved wall. The inner cavity is open at least one end along the axial direction of the main body 10. The main body 10 is provided with a plurality of spaced mounting holes 11. A steel wire bundle 20 is snapped into the mounting holes 11. The inner cavity is filled with concrete 30. The concrete 30 is fixedly connected to the inner wall of the main body 10 and the portion of the steel wire bundle 20 located in the inner cavity by pouring.

[0026] In detail, the main body 10 includes a curved wall, for example, the curved wall may have an elliptical cross-section or a circular cross-section.

[0027] The inner cavity is open at least at one end along the axial direction of the body 10. It can be that both ends of the inner cavity are open along the axial direction of the body 10 to penetrate the body 10, or the inner cavity is open at one end along the axial direction of the body 10 and closed at the other end.

[0028] The spaced mounting holes 11 are designed to create uniform and staggered fixing points for the wire bundles 20 on the main body 10. This allows the wire bundles 20 to be distributed in a quincunx or spiral pattern on the curved wall surface, ensuring that the brush generates alternating scrubbing force during rotation or reciprocating motion. This effectively covers the entire arc-shaped surface of the cutoff wall joint, preventing overlap or blind spots caused by excessively close spacing between adjacent wire bundles 20. Simultaneously, the pressure difference generated by the spacing enhances the efficiency of mud skin removal, improving the uniformity and thoroughness of the scrubbing. The mounting holes 11 can be formed on the main body 10 by drilling.

[0029] The concrete 30 is fixedly connected to the inner wall of the main body 10 and the part of the steel wire bundle 20 located in the inner cavity by pouring. In this way, when assembling the steel wire bundle 20 and the main body 10, the steel wire bundle 20 only needs to be inserted into the mounting hole 11, and the concrete 30 is poured into the inner cavity. After the concrete 30 solidifies, the fixed connection between the concrete 30 and the inner wall of the main body 10 and the part of the steel wire bundle 20 located in the inner cavity can be achieved.

[0030] According to the embodiments of this application, the curved wall of the cut-off wall joint brusher has a fixed curvature, which can be adapted to the curvature of the cut-off wall arc joint to be washed, thereby improving the compatibility between the main body 10 and the cut-off wall arc joint. This ensures that the brusher maintains uniform contact pressure during the brushing process, ensuring that the steel wire bundle 20 adheres to the joint surface and avoiding blind spots in localized brushing caused by curvature mismatch in traditional flat brushes. The mounting holes 11 intermittently engage the steel wire bundle 20 to form a flexible brush body, ensuring the uniformity of mud removal. The inner cavity is filled with concrete 30, forming a rigid whole with the shell. The self-weight increases the brushing pressure, and the concrete 30 also fixes the steel wire bundle 20 and the main body 10 structure, improving the stability of the device. The overall structure does not require complex connecting parts, the manufacturing process is simple, reducing on-site processing difficulty and cost, and it is suitable for efficient brushing operations in different construction environments.

[0031] According to the embodiments of the seepage barrier joint brushing device of this application, the steel wire bundle 20 includes multiple steel wires gathered together. The multiple steel wires form a flexible brush body, which can adapt to the surface curvature when contacting the seepage barrier joint. The dense bristles increase the contact area and improve the efficiency of mud removal. The gathered steel wires can enhance the overall structural strength of the steel wire bundle 20, prevent the breakage and detachment of individual steel wires, and extend the service life. The mounting hole 11 secures the steel wire bundle 20 and fixes it to the concrete 30 to ensure the stability of the position of the steel wire bundle 20. Under the action of gravity, it can maintain the uniform brushing pressure of the brushing device.

[0032] like Figure 4As shown, according to the embodiment of the seepage-proof wall joint brushing device of this application, a plurality of mounting holes 11 are arranged in a quincunx array. The plurality of mounting holes 11 are divided into first mounting holes 12 and second mounting holes 13. The quincunx array includes a plurality of first units A arranged in rows in a first direction and columns in a second direction. The first unit A includes a first mounting hole 12 located at the center and a plurality of second mounting holes 13 arranged around the first mounting hole 12. Two adjacent first units A share the same row of second mounting holes 13. In the direction of the row, two adjacent first units A share the same column of second mounting holes 13. The first direction is perpendicular to the second direction and parallel to the axial direction of the main body 10. The second direction extends along the circumference of the main body 10.

[0033] In the above embodiments, the multiple mounting holes 11 are arranged in a quincunx pattern to provide more mounting holes 11, ensuring that the wire bundles 20 are present in different directions. For ease of explanation, the concept of a first unit A is introduced. At the same time, for ease of explanation, the multiple mounting holes 11 are divided into first mounting holes 12 and second mounting holes 13. They are essentially mounting holes 11, but their positions in the smallest unit, the first unit A, are different. Two adjacent first units A share the same row of second mounting holes 13. In the row direction, two adjacent first units A share the same column of second mounting holes 13. This increases the density of mounting holes 11 and reduces the number of holes to be drilled. Finally, by setting the first mounting holes 12 and the second mounting holes 13, a honeycomb-shaped network of wire bundles 20 is formed in the circumference and axial direction of the main body 10, ensuring that each point on the surface of the arc joint is alternately washed by the wire bundles 20 in at least two directions, avoiding blind spots in the washing process and improving the mud peeling rate.

[0034] like Figure 4 As shown, in some embodiments, in the first unit A, the number of second mounting holes 13 corresponding to the first mounting hole 12 is 4; in some embodiments, in the first unit A, the number of second mounting holes 13 corresponding to the first mounting hole 12 is 6.

[0035] In some embodiments, each first unit A includes four second mounting holes 13, and the central angle between two adjacent second mounting holes 13 within the same first unit A is 30° to 90° in the row direction. Thus, by changing the central angle between two adjacent second mounting holes 13 within the same first unit A, the distribution density and brushing direction of the wire bundle 20 can be altered. For example, a smaller angle (e.g., 30°) can increase the density of the wire bundle 20, while a larger angle (e.g., 90°) can create more dispersed brushing points. The central angle can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, and 90°, etc.

[0036] like Figures 1-3As shown, in the seepage-proof wall joint brushing device according to an embodiment of this application, the main body 10 is cylindrical, and the free ends 41 of the steel wire bundle 20 are distributed on the cylindrical surface of the same diameter. The cylindrical shape of the main body 10 can be a standard diameter round tube. The cylindrical main body 10 provides radial constraint for the steel wire bundle 20, keeping its free ends 41 on the same circumferential plane. Combined with the uniform pressure generated by the weight of the main body 10, it ensures that the brush body forms a 360° annular brushing band when rotating or reciprocating. The synchronous contact of the ends of the steel wire bundle 20 makes the mud removal force evenly distributed. The continuous trajectory design of the cylindrical surface avoids the brushing blind spots caused by the discrete distribution of traditional brush bodies, and at the same time reduces the risk of steel wire bundle 20 breakage due to local stress concentration.

[0037] like Figures 1-3 As shown, according to the embodiment of the seepage-proof wall joint brushing device of this application, the main body 10 is also provided with two opposite snap-fit ​​holes 14. The two snap-fit ​​holes 14 are at different heights in the axial direction of the main body 10. The inner cavity is also provided with a hanging ring 40. The hanging ring 40 is bent into an inverted U-shape. The two free ends 41 of the hanging ring 40 are bent into L-shapes and are staggered and snapped into the snap-fit ​​holes 14 opposite to the free ends 41. The concrete 30 is fixedly connected to the hanging ring 40 by pouring.

[0038] In the above embodiment, the hook is used to connect to the lifting equipment, allowing the steel wire bundle 20 of the wall brush to contact the anti-seepage wall joint and move up and down, rubbing and scrubbing the mud off the joint. By setting two locking holes 14 at different heights along the axis of the main body 10, the hanging ring 40 can generate natural torque during hoisting, counteracting the tilting tendency caused by the weight of the wall brush itself. The two free ends 41 are bent into L-shapes and cooperate with the corresponding locking holes 14 to fix it like a pin. Combined with the bonding effect of the concrete 30, this ensures that the wall brush remains vertically stable during hoisting, preventing rotation and shaking. It also ensures that the hook will not loosen from the main body 10 for long-term use, extending the service life of the equipment. At the same time, the hanging ring 40 can also serve as a rigid support point, transmitting some of the pressure to the main body 10 through the L-shaped free ends 41, reducing stress concentration inside the concrete 30 and extending the overall service life.

[0039] In some embodiments, the diameter of the hanging ring 40 is larger than the diameter of the wire bundle 20. This is understood to enhance the structural strength of the hanging ring 40, ensuring that it will not deform or break due to its own weight or operational resistance during hoisting.

[0040] In some embodiments, the hanging ring 40 is engaged with the wire bundle 20. Thus, after the wire bundle 20 is first fixed to the main body 10, the hanging ring 40 is inserted through the inner cavity and engaged between the portions of the wire bundle 20 within the inner cavity, thereby positioning the hanging ring 40. Then, by pouring concrete 30, the hanging ring 40, the wire bundle 20, and the main body 10 are fixedly connected, thus completing the entire process, simplifying the manufacturing process, and reducing the number of components.

[0041] The specific process is as follows:

[0042] A drilling machine is used to drill holes in the main body 10 (steel pipe) in a quincunx pattern in both horizontal and vertical directions to form mounting holes 11. The diameter of the mounting holes 11 is determined according to the diameter of the steel wire bundle 203. The spacing of the mounting holes 11 in the first and second directions is reasonably determined to ensure that the steel wire bundle 20 can pass through the mounting holes 11 smoothly. After drilling, the steel wire bundle 20 is inserted through the holes and anchored into the main body 10 (steel pipe).

[0043] Step 2: Refer to the specifications and select the appropriate hanging ring 40, and place the hanging ring 40 at the center of the main body 10 (steel pipe).

[0044] Step 3: Fill the main body 10 (steel pipe) with concrete 30 to increase the weight of the wall brush, fix the steel wire bundle 20 and the hanging ring 40. The hanging ring 40 must be embedded to a certain depth.

[0045] Step 4: Connect the hanging ring 40 to the lifting equipment, lift the wall brusher with the lifting equipment, so that the steel wire bundle 20 of the wall brusher comes into contact with the concrete 30 anti-seepage wall joint and moves up and down to rub and scrub the mud off the joint.
