Description

Technical Field

[0001] This invention belongs to the field of construction cleaning technology, specifically relating to a construction process for a roughening and cleaning equipment based on cylindrical bridge piers. Background Technology

[0002] Currently, roughening technology is widely used in highway bridge deck paving, tunnel wall bonding, dams, canals, power plants, airports, water and underwater operations, and slag removal in subways, railways, and steel plants, but mainly on land. Column-type bridge piers refer to piers composed of one or more columns. After long-term use, the underwater or near-water portions of these piers often become contaminated and corroded, resulting in surface structural defects. Without cleaning, this poses a threat to structural quality and personnel safety. Furthermore, with socio-economic development, the number of bridges is gradually increasing, as is the number of existing column-type bridge piers, leading to increasing pressure on the construction, maintenance, and cleaning of these piers. In addition, urbanization has led to a near-saturation of column-type bridge piers, and related industries are shifting towards bridge maintenance. Therefore, the rapid maintenance industry for bridge piers has great potential, and pier roughening, as a pre-maintenance operation, urgently needs technological upgrading.

[0003] Traditional bridge pier roughening processes mostly rely on manual labor, which suffers from high costs, low efficiency, and poor construction results, while also posing corresponding safety hazards. Other mechanized construction methods, such as pneumatic drilling, suffer from uneven roughening depth and difficulty in controlling roughening quality. Electric hammer roughening is prone to safety accidents, and equipment damage, aging, and potential leakage are unsuitable for underwater operations. Large-scale specialized roughening machines are difficult to operate underwater and are not suitable for curved surface operations.

[0004] Based on this, the present invention provides a construction process for a chiseling and cleaning equipment based on cylindrical bridge piers to solve the above problems. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a construction process for a chiseling and cleaning equipment based on cylindrical bridge piers, so as to solve the problems in the prior art.

[0006] One embodiment of the present invention provides a construction process for a chiseling and cleaning equipment based on a cylindrical bridge pier. The chiseling and cleaning equipment includes a suspension support mechanism, a track support mechanism, and a chiseling and cleaning mechanism. The construction process includes the following steps:

[0007] Installation of suspension support mechanism: Install and fix the suspension support mechanism above the surface of the cylindrical pier to be roughened;

[0008] Track support mechanism installation: Connect the track support mechanism to the suspension support mechanism, and install the winch on the track support mechanism;

[0009] Installation of the chiseling and cleaning mechanism: Use the winch on the track support mechanism to hook up the chiseling and cleaning mechanism, so that the chiseling and cleaning mechanism is suspended on the surface to be chiseled on the cylindrical pier.

[0010] Mobile high-pressure cleaning: Start the winch and the chiseling and cleaning mechanism. Use the winch to move the chiseling and cleaning mechanism along the axial direction of the surface to be chiseled on the cylindrical pier. During the axial movement, the chiseling and cleaning mechanism uses high-pressure water jets to clean the surface to be chiseled.

[0011] After the winch moves the chiseling and cleaning mechanism axially to the axial edge of the surface to be chiseled, the rotating track support mechanism changes the high-pressure water jet sprayed by the chiseling and cleaning mechanism, and the winch moves the chiseling and cleaning mechanism axially in the opposite direction to the initial position to complete one cycle of cleaning.

[0012] High-pressure cyclic cleaning: After completing one cycle of cleaning, the track support mechanism is rotated again in the same direction to change the high-pressure water jet sprayed by the chiseling cleaning mechanism, and the cycle of cleaning is repeated several times to complete the surface chiseling of the cylindrical bridge pier.

[0013] In one embodiment, the suspension support mechanism includes an upper steel strip, a lower steel strip, several inclined tie tubes, and a horizontal tube. The installation steps of the suspension support mechanism specifically include:

[0014] The upper steel strip and the lower steel strip are installed and fixed above the surface of the cylindrical pier to be roughened, and rubber pads are placed between the upper steel strip and the cylindrical pier, and between the lower steel strip and the cylindrical pier.

[0015] One end of several inclined pipes is evenly connected to the upper steel strip, and one end of several horizontal pipes is evenly connected to the lower steel strip.

[0016] The ends of several inclined pipes away from the upper steel strip are connected and fixed to the ends of several horizontal pipes away from the lower steel strip.

[0017] In one embodiment, the track support mechanism includes an upper annular track, a lower annular track, a fixed plate, and a hanging plate. The installation steps of the track support mechanism specifically include:

[0018] Install the fixing plate on the upper ring track, and fix the upper ring track to the horizontal pipe through the fixing plate;

[0019] Connect the upper end of the hanging plate to the upper ring track, and fasten the lower end of the hanging plate to the lower ring track.

[0020] Install the winch at the bottom of the hanging plate.

[0021] In one embodiment, the chiseling and cleaning mechanism includes a support ring, a connecting block mounted on the support ring, and a plurality of water jet elastic modules. The installation steps of the chiseling and cleaning mechanism specifically include:

[0022] A winch is used to hook the connecting block on the support ring, so that the support ring and several water jet elastic modules on the support ring are suspended on the roughened surface of the cylindrical pier.

[0023] In one embodiment, the roughened surface of the cylindrical pier is divided into cleaning areas equal to the number of water jet elastic modules. Each cleaning area is cleaned by one water jet elastic module. The moving high-pressure cleaning step specifically includes:

[0024] Start the winch and the water jet elastic module in the chiseling and cleaning mechanism. Use the winch to move the chiseling and cleaning mechanism along the axial direction of the surface to be chiseled on the cylindrical pier. During the axial movement, several water jet elastic modules spray high-pressure water jets toward the corresponding chiseling surface cleaning area. Use the high-pressure water jets to clean the surface to be chiseled.

[0025] After the winch moves the chiseling and cleaning mechanism axially to the axial edge of the surface to be chiseled, the lower ring track in the track support mechanism is rotated, causing the hanging plate to drive the winch, support ring, and water jet elastic module to rotate. This changes the high-pressure water jet of each water jet elastic module to clean the remaining area within the cleaning zone. The winch then moves the chiseling and cleaning mechanism axially in the opposite direction to the initial position, completing one cycle of cleaning.

[0026] In one embodiment, the water jet elastic module includes a mounting part, an elastic part, a contact wheel, and a water jet nozzle;

[0027] The mounting part is mounted on the support ring. One end of the elastic part is connected to the mounting part, and the other end of the elastic part is set towards the chiseled surface. The contact wheel and the water jet nozzle are both set on the end face of the elastic part near the chiseled surface. The contact wheel is closer to the chiseled surface of the cylindrical pier than the water jet nozzle to prevent the covering material on the chiseled surface from damaging the water jet nozzle during the axial movement of the chiseled cleaning mechanism.

[0028] The construction process of the roughening and cleaning equipment based on cylindrical bridge piers provided in the above embodiments has the following beneficial effects:

[0029] 1. This construction process can not only meet the needs of cleaning and roughening cylindrical bridge piers, but also adapt to roughening operations of cylindrical bridge piers of different radii by adjusting the parameters of the high-pressure water nozzle and the steel strip diameter of the roughening and cleaning equipment. In addition, the roughening and cleaning equipment can also be used as a platform to carry different equipment for other surface operations of cylindrical bridge piers.

[0030] 2. The overall construction process has a wide range of applications, low cost, simple structure, and is easy to operate. Compared with other roughening methods, this process is safer, more stable in effect, and more convenient for the corresponding construction work on cylindrical bridge piers.

[0031] 3. Compared with traditional manual techniques, this construction process is automatic and efficient. It can perform large-area rapid pier roughening operations through a combination of axial movement and rotation. Its water jet elastic module can effectively adapt to the complex working conditions of the roughened surface (biological adhesion, pits, pockmarks, cracks, etc.). Secondly, the diameter of the steel strip can be adjusted according to different piers, making it widely adaptable. Finally, the equipment has a simple structure, is easy to operate, and has the potential for widespread promotion. Attached Figure Description

[0047] Reference Figures 1-9 One embodiment of the present invention provides a construction process for a chiseling and cleaning equipment based on a cylindrical bridge pier. The chiseling and cleaning equipment consists of a suspension support mechanism 200, a track support mechanism 300, and a chiseling and cleaning mechanism 400.

[0048] The suspension support mechanism 200 includes an upper steel strip 210, a lower steel strip 220, several inclined tie tubes 230 and a horizontal tube 240.

[0049] The track support mechanism 300 includes an upper ring track 310, a lower ring track 320, a fixing plate 330, and a hanging plate 340.

[0050] The chiseling and cleaning mechanism 400 includes a support ring 410, a connecting block 420 mounted on the support ring 410, and several water jet elastic modules 430. The connecting block 420 uses a snap-fit ​​mechanism. The water jet elastic module 430 includes a mounting part 431, an elastic part 432, a contact wheel 433, and a water jet nozzle 434. The mounting part 431 is mounted on the support ring 410. One end of the elastic part 432 is connected to the mounting part 431, and the other end of the elastic part 432 is positioned towards the chiseling surface 110. The contact wheel 433 and the water jet nozzle 434 are both located on the end face of the elastic part 432 near the chiseling surface 110. Because the chiseling surface has irregular coverings, the contact wheel 433 is closer to the chiseling surface 110 of the cylindrical pier 100 than the water jet nozzle 434 to prevent the irregular coverings on the chiseling surface 110 from damaging the water jet nozzle 434 during the axial movement of the chiseling and cleaning mechanism 400.

[0051] The roughened surface 110 of the cylindrical pier 100 is divided into cleaning areas, the same number as the number of water jet elastic modules 430. Each cleaning area is cleaned by one water jet elastic module 430. In this embodiment, there are eight water jet elastic modules 430, that is, the roughened surface 110 is divided into eight cleaning areas, each cleaning area occupies 1 / 8 of the area, and each cleaning area is cleaned by one water jet elastic module 430.

[0052] The construction process includes the following steps:

[0053] S100, Preliminary work: Measure the dimensions of the cylindrical pier 100, select the corresponding upper and lower steel strips and rubber pads, and prepare the appropriate vehicles (vehicles, ships).

[0054] S200, Transportation: Using vehicles to transport the components of each mechanism to the construction site.

[0055] S300, Installation of Suspension Support Mechanism 200: Install and fix the suspension support mechanism 200 above the roughened surface 110 of the cylindrical pier 100.

[0056] The specific installation process is as follows: the upper steel strip 210 and the lower steel strip 220 are installed and fixed to the top of the roughened surface 110 of the cylindrical pier 100 using bolts, welding, or other methods. Figure 2 As shown, rubber pads are installed between the upper steel strip 210 and the cylindrical pier 100, and between the lower steel strip 220 and the cylindrical pier 100, to prevent the upper steel strip 210 and the lower steel strip 220 from sliding during construction, thus playing an anti-slip role.

[0057] One end of several inclined tie pipes 230 is evenly connected to the upper steel strip 210, and one end of several horizontal pipes 240 is evenly connected to the lower steel strip 220. In this embodiment, there are three inclined tie pipes 230 and three horizontal pipes 240, which are equally spaced on the upper steel strip 210 and the lower steel strip 220 to increase the stability during support.

[0058] The ends of several inclined tie pipes 230 away from the upper steel strip 210 are connected and fixed to the ends of several horizontal pipes 240 away from the lower steel strip 220, so that the inclined tie pipes 230, horizontal pipes 240, and upper steel strip 210 / lower steel strip 220 are in a triangular stress distribution, thereby increasing the stability during support.

[0059] S400, Track Support Mechanism 300 Installation: Connect the track support mechanism 300 to the suspension support mechanism 200, and install the winch 500 on the track support mechanism 300.

[0060] The specific installation process is as follows: the fixing plate 330 is installed on the upper ring track 310, and the upper ring track 310 is fixedly connected to the horizontal pipe 240 through the fixing plate 330;

[0061] Connect the upper end of the hanging plate 340 to the upper ring track 310, and fasten the lower end of the hanging plate 340 to the lower ring track 320.

[0062] Install the winch 500 at the bottom of the hanging plate 340.

[0063] like Figure 4 As shown, three hanging plates 340 are used to install one winch 500 respectively. The hanging plate 340 consists of an upper outer shell 341, a lower outer shell 342, a sliding plate 343, and a hook 344. The upper outer shell 341 and the lower outer shell 342 are fixed with bolts, and a sliding groove is formed between the upper outer shell 341 and the lower outer shell 342. The sliding plate 343 is installed in the sliding groove, that is, the inner side of the upper outer shell 341 and the inner side of the lower outer shell 342 are both equipped with sliding plates 343. The hook 344 is fixed to the lower end of the lower outer shell 342. During installation, the upper groove of the hanging plate 340 is connected to the upper ring track 310, allowing the hanging plate 340 to slide along the upper ring track 310; the hook 344 at the lower end of the hanging plate 340 is fastened and fixed to the lower ring track 320, making the entire hanging plate 340 more stable when sliding along the upper ring track 310; eye bolts are installed on the bottom surface of the hook 344, and the winch 500 is installed on the bottom surface of the hook 344 using eye bolts.

[0064] S500, Chipping and Cleaning Mechanism 400 Installation: Use the winch 500 on the track support mechanism 300 to hook the chipping and cleaning mechanism 400, so that the chipping and cleaning mechanism 400 is suspended on the surface 110 to be chiseled on the cylindrical pier 100.

[0065] The specific installation process is as follows: the winch 500 is used to hook the connecting block 420 on the support ring 410, so that the support ring 410 and several water jet elastic modules 430 on the support ring 410 are suspended on the roughened surface 110 of the cylindrical pier 100.

[0066] like Figure 5 As shown, the winch 500 has an iron ring chain (or steel wire) and a hook. After the track support mechanism 300 is installed, the three winches 500 simultaneously lower the iron ring chain and hook, and use the hook to hook the connecting block 420 on the support ring 410 respectively, so that the support ring 410 and the water jet elastic module 430 on the support ring 410 are suspended on the roughened surface 110 of the cylindrical pier 100.

[0067] It should be noted that the support ring 410 of the chiseling and cleaning mechanism 400 consists of two semicircles. In step S200, after the components of each mechanism are transported to the construction site, the chiseling and cleaning mechanism 400 is floated on the water surface using a foam bucket or other floating material, and the two semicircles of the support ring 410 are fastened to the cylindrical pier 100, so that the winch 500 can hook the chiseling and cleaning mechanism 400 and suspend it on the surface 110 of the cylindrical pier 100 to be chiseled. After the winch 500 hooks the chiseling and cleaning mechanism 400, the foam bucket is removed.

[0068] S600, Mobile high-pressure cleaning: Start the winch 500 and the chiseling and cleaning mechanism 400. Use the winch 500 to move the chiseling and cleaning mechanism 400 axially along the surface 110 to be chiseled on the cylindrical pier 100. During the axial movement, the chiseling and cleaning mechanism 400 performs high-pressure cleaning on the surface 110 to be chiseled by high-pressure water jet.

[0069] After the winch 500 moves the chiseling and cleaning mechanism 400 axially to the axial edge of the surface to be chiseled 110, the rotating track support mechanism 300 changes the high-pressure water jet sprayed by the chiseling and cleaning mechanism 400, and the winch 500 moves the chiseling and cleaning mechanism 400 axially in the opposite direction to the initial position, completing one cycle of cleaning operation.

[0070] Specifically, the winch 500 and the water jet elastic module 430 in the chiseling and cleaning mechanism 400 are started. The winch 500 is used to move the chiseling and cleaning mechanism 400 axially (i.e., upward or downward) along the surface 110 to be chiseled on the cylindrical pier 100. During the axial movement, several water jet elastic modules 430 spray high-pressure water jets toward the corresponding chiseling surface 110 cleaning area, and use the high-pressure water jets to perform high-pressure cleaning on the surface 110 to be chiseled.

[0071] After the winch 500 moves the chiseling and cleaning mechanism 400 axially to the axial edge of the surface 110 to be chiseled (i.e., moves it upwards or downwards to the highest or lowest position of the surface 110), manually rotate the lower annular track 320 in the track support mechanism 300, causing the hanging plate 340 to drive the winch 500, support ring 410, and water jet elastic module 430 to rotate accordingly. Figure 8 As shown, the lower ring track 320 is rotated in one direction, which changes the high-pressure water jet of each water jet elastic module 430 to clean the remaining area within the cleaning area. The chiseling cleaning mechanism 400 is moved axially in the opposite direction to the initial position by the winch 500 to complete one cycle of cleaning operation.

[0072] like Figure 9As shown, for example, the initial position of the chiseling and cleaning mechanism 400 is at the highest position of the chiseling surface 110. When chiseling begins, the winch 500 controls the chiseling and cleaning mechanism 400 to move downward to the lowest position of the chiseling surface 110. Taking the cleaning of one cleaning area by a single water jet elastic module 430 as an example, during the downward movement, the water jet elastic module 430 uses high-pressure water jet to clean the chiseling surface 110. When it moves to the lowest position of the chiseling surface 110, the lower ring track 320 is rotated in one direction to change the high-pressure water jet of the water jet elastic module 430. Then, the winch 500 controls the chiseling and cleaning mechanism 400 to move upward to the highest position of the chiseling surface 110. During the movement, the high-pressure water jet is used to clean the chiseling surface 110. When the chiseling and cleaning mechanism 400 moves back to the initial position, one cycle of cleaning is completed. The other water jet elastic modules 430 clean the other cleaning areas in the same way.

[0073] As needed, the support ring 410 of the chiseling and cleaning mechanism 400 is equipped with several detection cameras to acquire image information of the surface 110 of the cylindrical pier 100 to be chiseled. The cameras are used to automatically control the start and stop of the winch 500 based on the acquired image information. That is, when the winch 500 controls the chiseling and cleaning mechanism 400 to move axially, after the detection cameras acquire the position of the chiseling and cleaning mechanism 400 at the axial edge of the surface 110 to be chiseled, the winch 500 is controlled to stop. This improves the cleaning efficiency of the surface 110 of the cylindrical pier 100 to be chiseled and avoids the chiseling and cleaning mechanism 400 from cleaning the surfaces of the cylindrical pier 100 that do not need to be chiseled.

[0074] S700, Circulating high-pressure cleaning: After completing one cycle of cleaning, rotate the track support mechanism 300 again in the same direction to change the high-pressure water jet sprayed by the chiseling cleaning mechanism 400, and repeat the cycle of cleaning several times to complete the surface chiseling of the cylindrical pier 100.

[0075] like Figure 9As shown, taking the cleaning of a cleaning area by a single water jet elastic module 430 as an example, after completing one cycle of cleaning, the lower ring track 320 is rotated again in the same direction, and the winch 500 and the water jet elastic module 430 are controlled to repeat the above cleaning action to repeat the cycle of cleaning multiple times to complete the roughening operation of the entire roughened surface 110. Since the roughened surface 110 is divided into eight cleaning areas, the roughening area occupied by each cleaning area is 1 / 8, and the total angle cleaned by a single water jet elastic module 430 to the cleaning area is 45°. If the rotation angle is 7.5° each time, the area cleaned by one cycle of cleaning is 1 / 3, that is, the total angle of one cycle of cleaning is 15°. At this time, repeating the cycle of cleaning twice more can complete the surface roughening operation of the cylindrical pier 100.

[0076] S800 Equipment Recovery: After the surface roughening of the cylindrical pier 100 is completed, the foam bucket is fixed on the roughening and cleaning mechanism 400 so that it floats on the water surface. The hook and iron ring chain of the winch 500 are then untied and connected to the transport vehicle to complete the recovery operation of the roughening and cleaning mechanism 400. The remaining mechanisms and parts are disassembled and transported to the transport vehicle in the reverse order of installation to complete the recovery operation of the entire equipment.

[0077] This construction process not only meets the needs of cleaning and roughening cylindrical bridge piers, but also adapts to roughening operations on cylindrical bridge piers of different radii by adjusting the parameters of the high-pressure water nozzles and the diameter of the steel strip of the roughening and cleaning equipment. Furthermore, the roughening and cleaning equipment can also serve as a platform to carry different equipment for other surface operations on cylindrical bridge piers. The overall construction process is widely applicable, low-cost, simple in structure, and easy to operate. Compared to other roughening methods, this process is safer, more stable in effect, and more convenient for corresponding construction operations on cylindrical bridge piers. Compared to traditional manual techniques, this construction process is automatic and efficient, capable of large-area rapid bridge pier roughening operations through a combination of axial movement and rotation. Its water jet elastic module can effectively adapt to complex working conditions on the roughened surface (biological adhesion, pits, pinholes, cracks, etc.). Secondly, the diameter of the steel strip can be adjusted according to different bridge piers, making it widely adaptable. Finally, the equipment has a simple structure, is easy to operate, and has the potential for widespread application.

[0078] As needed, the above-mentioned installation, setting, or connection methods include, but are not limited to, screws, riveting, welding or sleeve, fixing, etc. The installation, setting, or connection method shall be selected according to the working scenario.

A construction process of a chiseling cleaning equipment based on a cylindrical pier, characterized in that, The chiseling and cleaning equipment comprises a suspension support mechanism, a track support mechanism and a chiseling and cleaning mechanism, and the construction process comprises the following steps: Suspension support mechanism installation: the suspension support mechanism is installed and fixed above the surface to be chiseled of the cylindrical pier; Track support mechanism installation: the track support mechanism is connected with the suspension support mechanism, and a winch is installed on the track support mechanism; Chiseling and cleaning mechanism installation: the chiseling and cleaning mechanism is hooked by the winch on the track support mechanism, so that the chiseling and cleaning mechanism is suspended on the surface to be chiseled of the cylindrical pier; High-pressure cleaning movement: the winch and the chiseling and cleaning mechanism are started, the chiseling and cleaning mechanism is moved axially along the surface to be chiseled of the cylindrical pier by the winch, and the surface to be chiseled is cleaned by high-pressure water jet of the chiseling and cleaning mechanism during the axial movement; After the chiseling and cleaning mechanism is moved axially to the edge position of the surface to be chiseled by the winch, the track support mechanism is rotated to change the high-pressure water jet of the chiseling and cleaning mechanism, and the chiseling and cleaning mechanism is moved reversely to the initial position by the winch, thereby completing a cycle cleaning operation; High-pressure cleaning cycle: after the cycle cleaning operation is completed, the track support mechanism is rotated again in the same direction to change the high-pressure water jet of the chiseling and cleaning mechanism, and the cycle cleaning operation is repeated several times to complete the surface chiseling operation of the cylindrical pier; The suspension support mechanism comprises an upper steel belt, a lower steel belt, a plurality of inclined pipes and horizontal pipes, and the suspension support mechanism installation specifically comprises the following steps: The upper steel belt and the lower steel belt are respectively installed and fixed above the surface to be chiseled of the cylindrical pier, and rubber pads are arranged between the upper steel belt and the cylindrical pier and between the lower steel belt and the cylindrical pier; One end of each of the plurality of inclined pipes is connected with the upper steel belt, and one end of each of the plurality of horizontal pipes is connected with the lower steel belt; The other end of each of the plurality of inclined pipes is connected with the other end of each of the plurality of horizontal pipes; The track support mechanism comprises an upper annular track, a lower annular track, a fixed plate and a hanging plate, and the track support mechanism installation specifically comprises the following steps: The fixed plate is installed on the upper annular track, and the upper annular track is fixedly connected with the horizontal pipes through the fixed plate; The upper end of the hanging plate is connected with the upper annular track, and the lower end of the hanging plate is buckled with the lower annular track; The winch is installed at the bottom of the hanging plate; The chiseling and cleaning mechanism comprises a support ring, a connecting block installed on the support ring and a plurality of water jet elastic modules, and the chiseling and cleaning mechanism installation specifically comprises the following steps: The connecting block on the support ring is hooked by the winch, so that the support ring and the plurality of water jet elastic modules on the support ring are suspended on the surface to be chiseled of the cylindrical pier; The surface to be chiseled of the cylindrical pier is divided into cleaning areas with the same number as the water jet elastic modules, and each cleaning area is cleaned by one water jet elastic module, and the high-pressure cleaning movement specifically comprises the following steps: Start the winch and the water jet elastic module in the chiseling and cleaning mechanism. Use the winch to move the chiseling and cleaning mechanism along the axial direction of the surface to be chiseled on the cylindrical pier. During the axial movement, several water jet elastic modules spray high-pressure water jets toward the corresponding chiseling surface cleaning area. Use the high-pressure water jets to clean the surface to be chiseled. After the winch moves the chiseling and cleaning mechanism axially to the axial edge of the surface to be chiseled, the lower ring track in the track support mechanism is rotated, causing the hanging plate to drive the winch, support ring, and water jet elastic module to rotate. This changes the high-pressure water jet of each water jet elastic module to clean the remaining area within the cleaning zone. The winch then moves the chiseling and cleaning mechanism axially in the opposite direction to the initial position, completing one cycle of cleaning. The water jet elastic module includes a mounting part, an elastic part, a contact wheel, and a water jet nozzle; The mounting part is mounted on the support ring. One end of the elastic part is connected to the mounting part, and the other end of the elastic part is set towards the chiseled surface. The contact wheel and the water jet nozzle are both set on the end face of the elastic part near the chiseled surface. The contact wheel is closer to the chiseled surface of the cylindrical pier than the water jet nozzle to prevent the covering material on the chiseled surface from damaging the water jet nozzle during the axial movement of the chiseled cleaning mechanism.
