Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a building construction auxiliary device, specifically a steel brushing device for underground continuous wall. Background Technology

[0002] During construction, the quality and efficiency of cleaning the H-beam joints of diaphragm walls directly affect the waterproofing effect and construction progress. During concrete pouring, flow around the H-beam joints may occur, and traditional brushing techniques often fail to completely remove this flow, leading to defects such as mud inclusions and voids at the joints, affecting the waterproofing effect and structural integrity of the diaphragm wall. For detailed areas such as the corners of the H-beams and the angles between the ribs and flanges, ordinary brushes are difficult to apply completely, leaving dirt residue that can cause leakage in subsequent construction. When the soil is hard or contains hard impurities such as calcareous nodules, conventional wire brushes or shovels are insufficient to effectively remove them, potentially resulting in incomplete cleaning of the joint surface and affecting subsequent construction quality. Since a single brushing session is often insufficient for achieving the desired cleaning effect, multiple brushing sessions are frequently required, especially in cases of flowing concrete or hard soil, significantly increasing the total brushing time and extending the construction period. In addition, in existing wall brushing processes, if a crawler crane is used to hoist a wire brush for wall brushing, the equipment needs to be switched after the trenching machine is completed, which increases construction time and cost. Moreover, frequent equipment switching may also affect construction progress and efficiency.

[0003] In summary, traditional brushing techniques suffer from drawbacks such as poor brushing results, impacting joint waterproofing and integrity, low brushing efficiency, demanding site requirements, and cumbersome procedures. Therefore, a new device is needed to solve the quality problems of cleaning H-beam joints, reduce process changes, save operation time, and improve efficiency. Summary of the Invention

[0004] In order to solve a series of problems in the existing wall brushing process, such as incomplete cleaning, low brushing efficiency, high requirements for construction sites, and cumbersome procedures, this utility model provides a steel wall brushing device for underground continuous walls.

[0005] This utility model is achieved using the following technical solution:

[0006] A continuous underground wall type steel brush wall device includes a back plate installed on the outer facade of the trenching machine bucket frame. The upper end of the back plate has a hanging hole, and the lower end of the back plate facing the trenching machine bucket frame has a connecting slot. Side plates are fixed on both sides of the back plate facing away from the trenching machine bucket frame. A shovel plate is fixed at the lower end between the two side plates. Multiple rows of paired upper and lower clamping plates are installed between the two side plates above the shovel plate. A steel brush is clamped between the upper and lower clamping plates. Multiple sets of guide plates are welded between the two side plates above the steel brush. The guide plates are parallel to each other. An overflow hole is opened between the guide plates on the back plate.

[0007] During implementation, the back plate installed on the outer facade of the troughing machine bucket frame is made of 2cm thick steel plate. The upper end of the back plate has hanging holes, which correspond to the mounting holes on the troughing machine fixing frame. The upper end of the brushing device is connected to the troughing machine fixing frame by bolts passing through the hanging holes and mounting holes in sequence. The lower end of the back plate facing the troughing machine bucket frame is provided with a connecting slot, which cooperates with the troughing machine grab bucket.

[0008] A reinforcing rib is welded to the center of the side of the back plate away from the bucket frame of the troughing machine. The reinforcing rib is in the shape of a herringbone. The lower end of the reinforcing rib is welded to the uppermost clamping plate, and the upper end of the reinforcing rib is located below the hanging hole.

[0009] Side plates are fixed on both sides of the back plate away from the bucket frame of the trenching machine. The two side plates are arranged opposite each other, and a shovel is fixed at the lower end between the two side plates. The two ends of the shovel are welded to the edge of the side plate and are used to deal with the soil in the inside corner of the trench of the diaphragm wall. Alternatively, the shovel style 7 can be improved and replaced with a high-strength steel flat shovel to increase the contact area between the wall brush and the H-shaped steel joint, so as to further improve the cleaning effect.

[0010] Between the two side plates, above the shovel plate, are multiple rows of paired upper and lower clamping plates. Steel brushes are clamped between the upper and lower clamping plates to improve their stability. The steel brushes are made of multiple strands of high-carbon steel wire rope, and their length is greater than that of the upper clamping plates to facilitate their extension for cleaning. Specifically, steel brush mounting holes are opened on the back plate between the upper and lower clamping plates. Steel brush sleeves are fixed in the mounting holes, and steel brushes are fixed in the sleeves. The distance between two adjacent steel brush mounting holes is greater than the diameter of the mounting holes.

[0011] Multiple sets of guide plates are welded between the two side plates above the steel brush. The guide plates are fixed to the surface of the reinforcing rib and are parallel to each other. An overflow hole is opened between the guide plates on the back plate. The overflow hole is located on both sides of the connection between the reinforcing rib and the back plate. In addition to overflow during use, it can also be used for the suspension installation of the device.

[0012] When using, first insert and fix the end of the steel brush into the steel brush sleeve, then weld the steel brush sleeve into the steel brush mounting hole. When welding, ensure that the steel brush is perpendicular to the back plate and that the weld is firm. Install the upper and lower clamping plates so that the steel brush passes through the space between the upper and lower clamping plates. The brush wall assembly is now complete.

[0013] Use bolts to pass through the hanging holes and mounting holes on the troughing machine's mounting bracket to connect the upper end of the wall brushing device to the troughing machine's mounting bracket. At the same time, insert the troughing machine's grab bucket into the connecting slot to complete the installation of the wall brushing device.

[0014] By using the bucket frame of the trenching machine to drive the wall brushing device to move up and down, the joint surface of the underground continuous wall is cleaned and brushed.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model provides a diaphragm wall steel brushing device. By improving the steel brush of the joint brushing device and optimizing the installation method of the brushing device, a brushing device integrating a mud scraper and a steel brush is proposed. The brushing device is connected and fixed to the outer surface of the trenching machine bucket frame. The bucket frame of the trenching machine drives the fixed frame to move up and down, thereby cleaning and brushing the joint surface of the diaphragm wall.

[0017] The development of a wall-brushing device for H-beam joints of diaphragm walls has significantly improved the wall-brushing effect, solved the quality problem of cleaning H-beam joints, reduced process changes, saved wall-brushing time, improved construction efficiency, saved energy and increased efficiency, and achieved good economic and technical benefits.

[0022] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0023] A type of steel brushing device for underground continuous wall, such as Figures 1-3As shown: A back plate 2, made of 2cm thick steel plate, is installed on the outer facade of the trenching machine's bucket frame. The upper end of the back plate 2 has a hanging hole 1, which corresponds to the mounting hole on the trenching machine's fixing frame. Bolts are used to sequentially pass through the hanging hole 1 and the mounting hole to connect the upper end of the wall-brushing device to the trenching machine's fixing frame. A connecting slot 8 is provided at the lower end of the back plate 2 facing the trenching machine's bucket frame. The connecting slot 8 engages with the trenching machine's grab bucket. In this embodiment, a crane is used to insert the connecting slot 8 on the back side wall of the assembled wall-brushing device through the mud discharge hole on the scraper of the trenching machine's grab bucket frame, and it is fixed with a pin. By utilizing the trenching machine's bucket frame to drive the wall-brushing device to move up and down, the joint surface of the underground continuous wall is cleaned and brushed.

[0024] A reinforcing rib 10 is welded to the center of the side of the back plate 2 away from the bucket frame of the troughing machine. The reinforcing rib 10 is in the shape of a herringbone. The lower end of the reinforcing rib 10 is welded to the upper clamping plate 4 located at the top. The upper end of the reinforcing rib 10 is located below the hanging hole 1.

[0025] Side plates 6 are fixed on both sides of the back plate 2, which is away from the bucket frame of the trenching machine. The two side plates 6 are arranged opposite each other, and a shovel 7 is fixed at the lower end between the two side plates 6. The shovel 7 can be a commercially available steel chisel. The two ends of the shovel 7 are welded to the edge of the side plate 6 and are used to treat the soil in the inside corner of the trench of the diaphragm wall. Alternatively, the style of the shovel 7 can be improved by using a high-strength steel flat shovel instead, so as to increase the contact area between the wall brush and the H-shaped steel joint and further improve the cleaning effect.

[0026] Between the two side plates 6, above the shovel plate 7, multiple rows of paired upper clamping plates 4 and lower clamping plates 11 are installed. In this embodiment, three rows of steel brushes 5 are provided, that is, even three pairs of upper clamping plates 4 and lower clamping plates 11. The steel brushes 5 are sandwiched between the upper clamping plates 4 and lower clamping plates 11 to improve the stability of the steel brushes 5. The distance between two adjacent rows of steel brushes 5 is equal, so as to clean evenly and avoid repeated work areas.

[0027] The steel brush 5 is made of multiple strands of high-carbon steel wire rope. The high-carbon steel wire rope can be cut and bundled according to the length to be used. The length of the steel brush 5 is greater than that of the upper clamping plate 4, and the extension length of the steel brush 5 is 15cm, which facilitates the extension of the steel brush 5 for cleaning. Specifically, a steel brush mounting hole 12 is opened on the back plate 2 between the upper clamping plate 4 and the lower clamping plate 11. A 4cm long steel brush sleeve is fixed in the steel brush mounting hole 12, and the steel brush 5 is fixed in the steel brush sleeve. The end of the steel brush 5 is firmly welded, and the welded end of the steel brush 5 is polished smooth. The distance between two adjacent steel brush mounting holes 12 is greater than the diameter of the steel brush mounting hole 12, that is, the distance between two adjacent steel brush mounting holes 12 is 5cm, and the diameter of each steel brush mounting hole 12 is 3cm.

[0028] Between the two side plates 6, above the steel brush 5, multiple sets of guide plates 3 are welded. The guide plates 3 are fixed on the surface of the reinforcing rib 10 and are parallel to each other. The back plate 2 is located between the guide plates 3 and has overflow holes 9. The overflow holes 9 are located on both sides of the connection between the reinforcing rib 10 and the back plate 2. In addition to overflow during use, they can also be used for the suspension installation of the device.

[0029] In use, first insert and fix the end of the steel brush 5 into the steel brush sleeve, then weld the steel brush sleeve into the steel brush mounting hole 12. When welding, ensure that the steel brush is perpendicular to the back plate 2 and that the welding is firm. Install the upper clamping plate 4 and the lower clamping plate 11 so that the steel brush 5 passes through the space between the upper clamping plate 4 and the lower clamping plate 11. The brush wall device is then assembled.

[0030] Use bolts to pass through the hanging hole 1 and the mounting hole on the troughing machine frame to connect the upper end of the wall brushing device to the troughing machine frame. At the same time, insert the troughing machine grab bucket into the connecting slot 8 to complete the installation of the wall brushing device.

[0031] By using the bucket frame of the trenching machine to drive the wall brushing device to move up and down, the joint surface of the underground continuous wall is cleaned and brushed.
