Description

Technical Field

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

[0002] Currently, the application of diaphragm wall construction methods in deep foundation pit engineering is becoming increasingly widespread. Joint types include I-beams, interlocking pipes, and cross-plates. The joints between the initial and subsequent sections of the diaphragm wall are the weakest points in the overall waterproofing of the retaining structure. I-beam joints are prone to flow around the joints or sand and mud inclusions, which are the main causes of leakage. Traditional diaphragm wall cleaning often uses prefabricated wall brushes, which are used by lifting and pulling the joints at an angle with a truck crane. These prefabricated wall brushes have limited functionality, require frequent switching depending on actual needs, and are slow and uneconomical. Therefore, a solution is urgently needed.

[0003] The above content is only used to help understand the technical solution of this utility model and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wall brushing device. This device can not only prevent the I-beam joint from being damaged and forming a water seepage channel during the construction of grab bucket trenching machine and double wheel milling trenching machine, thus improving the quality of wall brushing, but also improve the brushing effect when used in conjunction with the original brushing device, thus greatly saving the project cost.

[0014] (2) The device provided by this utility model can simultaneously provide a shovel and a brush. It is not only multifunctional, but the wire brush head can be disassembled and replaced with a variable diameter at any time. The shovel is replaceable and suitable for various sizes of diaphragm walls and various joint types such as I-beams, constricted pipes, and cross plates. During construction, the mud skin and surrounding slag concrete are removed by shoveling from the bottom and brushing from the top, reducing the brushing frequency from the original specification requirement of 30 times / section to 20 times / section. This ensures the depth of joint treatment, and as the excavation progresses, there is no leakage on the surface of the diaphragm wall, avoiding the risk of water and sand inrush during subsequent deep foundation pit excavation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0024] Example

[0025] See Figure 1-6 As shown:

[0026] This utility model provides a wall brushing device, including: a connecting plate 10, a vertical plate 20, and a scraping brush assembly.

[0027] One side of the connecting plate 10 is connected to the vertical plate 20. Bolt holes 11 are provided on the connecting plate 10, through which the connecting plate 10 and the grooving machinery can be detachably connected. In practical applications, the grooving machinery, such as a grooving machine, can be used as a device for brushing the walls of diaphragm walls.

[0028] The scraper assembly is installed on the other side of the connecting plate 10, and is equipped with a brush head 41 and rake teeth 51 for scraping the diaphragm wall. The brush head 41 and rake teeth 51 are detachably connected to the connecting plate 10. Furthermore, the brush head 41 is made of steel wire and comes in various specifications, allowing for timely replacement according to construction needs. In practical applications, operators can adjust the specifications of the brush head 41 and rake teeth 51 according to the scraping requirements of the diaphragm wall, making the scraping device more flexible and convenient to use.

[0029] The scraper assembly includes a brush head and a scraper section. The brush head is vertically connected to the top of the vertical plate 20, and the brush head 41 is detachably connected to the brush head. The scraper section is vertically connected to the bottom of the vertical plate 20, and the rake teeth 51 are detachably connected to the scraper section.

[0030] The brush head mainly consists of a right-angled triangular plate 21, a lower clamping plate 31, an upper clamping plate 32, a bolt 33, and a horizontal bar 34. There are two horizontal bars 34, each perpendicularly connected to the vertical plate 20. One right-angled side of the right-angled triangular plate 21 is perpendicularly connected to the vertical plate 20, and the top of the right-angled triangular plate 21 is connected to the bottom of the horizontal bar 34. Both ends of the lower clamping plate 31 are connected to the two horizontal bars 34 respectively. The upper clamping plate 32 is positioned above the lower clamping plate 31. The bolt 33 passes through through holes in the lower clamping plate 31 and the upper clamping plate 32, fixing the brush head 41 between them.

[0031] With this setup, during actual use, i.e., during the brushing process, the right-angled triangular plate 21 and the horizontal bar 34 can provide stable support for the lower clamping plate 31 and the upper clamping plate 32, so that the force on the brush head 41 can be stably transmitted to the right-angled triangular plate 21 and the horizontal bar 34, avoiding excessive deformation and improving the stability of the entire device.

[0032] In addition, in actual use, considering the area required for brushing the wall in a single operation, the lower clamping plate 31 and the upper clamping plate 32 are each provided with at least two different lengths. The longer lower clamping plate 31 and the upper clamping plate 32 can accommodate more brush heads 41, which facilitates replacement and improves the flexibility of the device.

[0033] The shovel section includes right-angled trapezoidal side plates 22, a shovel blade 23, and ribs. There are two right-angled trapezoidal side plates 22, and the right-angled sides of the two right-angled trapezoidal side plates 22 are perpendicularly connected to the vertical plate 20. The two ends of the shovel blade 23 are connected to the hypotenuses of the two right-angled trapezoidal side plates 22, and the two ends of the ribs are connected to the shovel blade 23 and the vertical plate 20, respectively. The rake teeth 51 are evenly spaced along the length of the bottom end of the shovel blade 23.

[0034] By setting ribs, the support of the vertical plate 20 for the blade 23 can be strengthened. During the use of the blade 23, the blade 23 is not prone to excessive deformation, and the force it receives can be transmitted to the vertical plate 20 through the right-angled trapezoidal side plate 22 and the ribs, thus improving the flexibility of the entire device.

[0035] When the brush head 41 is not required during the construction of the diaphragm wall, a clamping plate 35 is also provided. The clamping plate 35 is placed between the lower clamping plate 31 and the upper clamping plate 32, and the end face of the clamping plate 35 is set as an inclined surface, with rake teeth 51 evenly spaced along the length direction on the end face. The end face can also be made of small shovels. The connection between the rake teeth 51 and the shovels 23 can be welded, and the rake teeth 51 have different specifications.

[0036] The device provided by this utility model can be configured as either an upper brush and a lower shovel or an upper shovel and a lower shovel. The specifications of the lower clamping plate 31, upper clamping plate 32, rake teeth 51, and brush head 41 can be changed and adjusted according to actual usage needs, which improves the flexibility of the device and also enhances its effectiveness.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
