Description

Technical Field

[0001] This invention relates to the field of underground wall waterproofing construction technology, specifically to a method and apparatus for waterproofing construction within underground continuous walls. Background Technology

[0002] During the construction of diaphragm walls, in order to make the diaphragm walls more suitable for the underground humidity environment, the inner walls of the diaphragm walls need to be coated with waterproof paint to reduce the strength and moisture resistance of the diaphragm walls.

[0003] In the process of applying waterproof coating to diaphragm walls, manual application relies on holding the roller by hand. It is difficult to control the force manually, making it impossible to ensure that the thickness of the waterproof layer on each part of the wall is consistent. Moreover, the roller often becomes thinner later in the application process due to insufficient coating, requiring it to be dipped in coating again. After being dipped in coating again, the original coating on the roller is inconsistent, resulting in inconsistent coating amounts on each part of the roller. Consequently, it is difficult to maintain a consistent coating thickness on the wall. Summary of the Invention

[0007] As a further aspect of the present invention, the movable frame is provided with a cleaning component, which includes a squeezing component and a rejection component. The lower end of the squeezing component automatically abuts against the surface of the coating roller to squeeze out the water on the coating roller. The rejection component can slide on the surface of the coating roller to clean the impurities adhering to the coating roller. The squeezing component includes an upper positioning frame. The upper positioning frame is fixedly installed on the upper surface of the movable frame. A plurality of compression springs are fixedly installed on the lower surface of the upper positioning frame. The squeezing component is fixedly installed at the lower end of the compression spring. In its natural state, the lower end of the squeezing component abuts against the surface of the coating roller.

[0008] As a further embodiment of the present invention, the rejection component includes a connecting frame, a connecting frame is fixedly installed on one side of the movable frame, a threaded rod is rotatably installed on the connecting frame, a cleaning component is rotatably installed on the threaded rod, a limit rod is slidably connected inside the cleaning component, the limit rod is fixedly connected between the connecting frames, and a third transmission component is provided between the threaded rod and the connecting seat.

[0009] As a further embodiment of the present invention, a threaded column is rotatably connected inside the movable frame, and a drive motor is fixedly installed at the upper end of the threaded column. The output end of the drive motor is fixedly connected to the threaded column. There are two sets of threaded columns and four sets of mounting frames. Adjacent mounting frames are kept perpendicular to each other.

[0010] As a further embodiment of the present invention, the movable frame is provided with a sliding groove, a slider is slidably connected in the sliding groove, a toothed plate is fixedly connected to the slider, a drive gear is rotatably mounted on the lower end of the movable frame, the drive gear meshes with the toothed plate, a paint can is fixedly mounted on the lower end of the toothed plate, the upper end of the paint can is wide-mouthed, a micro motor is fixedly mounted on the movable frame, and the output end of the micro motor is fixedly connected to the drive turntable.

[0011] As a further embodiment of the present invention, the toothed plates are symmetrically arranged on the movable frame, and a forward and reverse motor is provided on the movable frame. The output end of the forward and reverse motor meshes with the drive gear. Two sets of drive gears are provided, and the two sets of drive gears mesh with each other. One side of the drive gear meshes with each other, and the other side meshes with the toothed plates.

[0012] A method for waterproofing construction within a diaphragm wall, applicable to the waterproofing construction device for diaphragm walls as described in any one of claims 1-7, wherein the specific steps of the construction method are as follows:

[0013] Step 1: Turn on the micro motor and drive motor. The micro motor drives the active turntable to rotate. The rotation of the active turntable drives the coating roller to rotate through the second transmission component and the first transmission component. At the same time, the drive motor drives the threaded column to rotate, driving the movable frame to move up and down.

[0014] Step 2: When the movable frame moves from the upper end to the lower end of the threaded column, the insert rod of the active turntable slides into the driven turntable, causing the driven turntable to rotate. The rotation of the driven turntable causes the mounting frame to rotate 90 degrees.

[0015] Step 3: After the mounting bracket stops rotating, the active turntable continues to repeat Step 1. The forward and reverse motor drives the active gear to rotate. The rotation of the active gear causes the toothed plate to move upward, which in turn causes the paint tank to move upward, so that the lower coating roller is immersed in the paint tank.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention utilizes the cooperation between an active turntable, a driven turntable, and an inner connecting shaft. The active turntable rotates, causing the driven turntable to rotate 90 degrees periodically. Simultaneously, the active turntable continuously drives the coating rollers on the mounting frame to rotate. The rotating coating rollers apply the waterproof coating to the underground wall. Multiple sets of coating rollers alternately apply the coating to reduce uneven coating caused by repeated dipping of the same coating roller. In addition, it ensures that the waterproof coating of the wall covering can be continuous and uninterrupted, without waiting for the rollers to dip in the coating. It also ensures that the number of rotations of each set of coating rollers on the wall surface is consistent, thereby ensuring a consistent coating thickness on the coating roller surface.

[0018] 2. This invention utilizes the cooperation between an active turntable and a driven turntable. The active turntable drives the coating roller to rotate continuously, allowing the waterproof coating on the coating roller to be applied to the underground wall. Additionally, after rotating for a certain period, the active turntable drives the driven turntable to rotate and replace the coating roller closer to the underground wall. This ensures that the dwell time and number of rotations of the coating roller on the wall are the same, preventing the coating thickness from becoming thinner due to limited coating on the coating roller. The active turntable driving the driven turntable can periodically replace the coating roller, preventing insufficient waterproof coating thickness due to insufficient waterproof coating on the coating roller.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1 -

[0033] Figure 9This invention provides a technical solution: a waterproofing construction device for underground continuous walls, including a movable frame 1, an outer connecting shaft 17 rotatably mounted on the movable frame 1, multiple sets of mounting frames 9 fixedly mounted on the outer connecting shaft 17, a rotating shaft 10 rotatably mounted on the end of the mounting frame 9 away from the outer connecting shaft 17, an application roller 8 fixedly connected between the rotating shafts 10, an inner connecting shaft 16 rotatably connected inside the outer connecting shaft 17, a first transmission component 15 provided between the inner connecting shaft 16 and the rotating shaft 10, a driven turntable 18 fixedly mounted on the outer connecting shaft 17, an active turntable 19 provided on one side of the driven turntable 18, the active turntable 19 rotates continuously, driving the driven turntable 18 to rotate at a certain angle at regular intervals, the active turntable 19 is rotatably mounted on the movable frame 1, and a second transmission component 20 is provided between the active turntable 19 and the inner connecting shaft 16.

[0034] Before using this invention, the device must be assembled, such as... Figure 1 As shown in the figure, the upper part of the device is viewed from above and below. Figure 1 The left end of the device is viewed approximately from the front. The following description will use the device's orientation and will not be repeated.

[0035] During operation, the drive motor 3 and the micro motor 28 are turned on. The micro motor 28 rotates, driving the active turntable 19 to rotate. The continuous rotation of the active turntable 19 drives the inner connecting shaft 16 to rotate via the second transmission component 20. The rotation of the inner connecting shaft 16 drives the rotating shaft 10 to rotate via the first transmission component 15. The rotation of the rotating shaft 10 drives the application roller 8 to rotate. The application roller rotates on the wall surface, adhering the waterproof coating on its surface to the wall. After the active turntable 19 rotates for a certain period of time, it drives the driven turntable 18 to rotate. The rotation of the driven turntable 18 drives the mounting bracket 9 to rotate. The rotation of the mounting bracket 9 drives the lowest application roller 8 to move to a position close to the wall. Then the active turntable 19 continues to rotate. The coating roller 8 is driven to rotate, ensuring that the coating time on the wall is consistent each time, the number of rotations of the coating roller 8 on the wall for a fixed length of coating is also the same, and the adhesion force between the coating roller 8 and the underground wall surface is consistent. This ensures that the thickness and uniformity of the waterproof coating applied by the coating roller 8 are consistent each time. Multiple sets of coating rollers 8 are used alternately to apply the waterproof coating. After each application, the surface of the coating roller 8 is automatically cleaned before it is automatically dipped in the coating. This ensures that the thickness of the waterproof coating adhering to the surface of the coating roller 8 is consistent and uniform each time, thus ensuring that the thickness of the coating applied by the coating roller 8 on the underground wall surface is consistent and uniform.

[0036] This invention utilizes the cooperation between the active turntable 19, the driven turntable 18, and the inner connecting shaft 16. The active turntable 19 rotates, causing the driven turntable 18 to rotate 90 degrees periodically. Simultaneously, the active turntable 19 continuously drives the coating roller 8 on the mounting frame 9 to rotate. The rotating coating roller 8 applies the waterproof coating on its surface to the underground wall. Multiple sets of coating rollers 8 alternately apply the coating to reduce uneven coating on the surface of the coating roller 8 caused by repeated dipping of the same coating roller 8. In addition, it ensures that the waterproof coating of the wall covering can be continuous and uninterrupted, without waiting for the roller to dip in the coating. It also ensures that the number of rotations of each set of coating rollers 8 on the wall surface is consistent, thereby ensuring a consistent coating thickness on the surface of the coating roller 8.

[0037] As a further embodiment of the present invention, a notch plate 23 is fixedly installed on the active turntable 19, an embedded rod 22 is fixedly installed on one side of the notch plate 23, a connecting seat 25 is fixedly installed on the notch plate 23, a second transmission member 20 is provided between the connecting seat 25 and the inner connecting shaft 16, the edge of the driven turntable 18 fits with the edge of the notch plate 23, an embedded groove 24 is provided on the driven turntable 18, and the embedded rod 22 matches the embedded groove 24.

[0038] During operation, the rotating drive disc 19 drives the notched plate 23, connecting seat 25, and inserting rod 22 to rotate. The connecting seat 25 rotates continuously with the drive disc 19. The rotation of the connecting seat 25 drives the inner connecting shaft 16 to rotate via the second transmission component 20. Simultaneously, the notched plate 23 rotates with the drive disc 19. As the notched plate 23 rotates with the drive disc 19, the notch position of the notched plate 23 shifts towards the driven disc 18. The inserting rod 22 on the notched plate 23 automatically inserts into the inserting groove 24 of the driven disc 18, thereby causing the driven disc 18 to rotate 90 degrees under the action of the inserting rod 22, changing its position closer to the ground. The application roller 8 on the lower wall is avoided. The driven turntable 18 rotates at the same angle each time to replace the application roller 8 closest to the underground wall. After the active turntable 19 rotates for a fixed time, it automatically drives the driven turntable 18 to rotate, thereby driving the replacement of the application roller 8. This ensures that the application time of each application roller 8 on the underground wall is uniform and the same. After the roller is replaced, the notch plate 23 on the active turntable 19 abuts against the edge of the driven turntable 18 to restrict the rotation of the driven turntable 18. This prevents the mounting frame 9 from rotating after the roller is replaced and avoids discontinuous or uneven application of the waterproof layer on the underground wall due to the unstable position of the application roller 8.

[0039] This invention utilizes the cooperation between the active turntable 19 and the driven turntable 18. The active turntable 19 drives the application roller 8 to rotate continuously, allowing the waterproof coating on the application roller 8 to be applied to the underground wall. In addition, after the active turntable 19 rotates for a certain period of time, it drives the driven turntable 18 to rotate and change the application roller 8 closer to the underground wall. This ensures that the dwell time and number of rotations of the application roller 8 on the wall are the same, preventing the application roller 8 from becoming thinner due to limited coating. The active turntable 19 driving the driven turntable 18 to rotate can replace the application roller 8 at regular intervals, preventing insufficient waterproof coating thickness due to insufficient waterproof coating on the application roller 8.

[0040] As a further aspect of the present invention, a cleaning component is provided on the movable frame 1. The cleaning component includes a squeezing component and a rejection component. The lower end of the squeezing component automatically abuts against the surface of the coating roller 8 to squeeze out the water on the coating roller 8. The rejection component can slide on the surface of the coating roller 8 to clean the impurities adhering to the coating roller 8. The squeezing component includes an upper positioning frame 2. The upper positioning frame 2 is fixedly installed on the upper surface of the movable frame 1. A plurality of compression springs 14 are fixedly installed on the lower surface of the upper positioning frame 2. The lower end of the compression springs 14 is fixedly installed with a squeezing component 11. In a natural state, the lower end of the squeezing component 11 abuts against the surface of the coating roller 8.

[0041] During operation, after the coating roller 8 coats the surface of the wall, the lower coating roller 8 rotates to the wall position, and the coating roller 8 at the wall position rotates to the extrusion component position, where the extrusion component abuts against the coating roller 8. Meanwhile, the coating roller 8 at the extrusion component rotates to the removal component position. When the coating roller 8 applies waterproof coating to the wall surface, the uppermost coating roller 8 also rotates under the action of the first transmission component 15 and the second transmission component 20. The extrusion component abuts against the surface of the coating roller 8, and the coating roller 8 rotates at the lower end of the extrusion component, causing the residual waterproof coating inside the coating roller to be squeezed and fall to the bottom.

[0042] As a further embodiment of the present invention, the removal component includes a connecting frame 4. The connecting frame 4 is fixedly installed on one side of the movable frame 1. A threaded rod 6 is rotatably installed on the connecting frame 4. A cleaning component 7 is rotatably installed on the threaded rod 6. A limit rod is slidably connected inside the cleaning component 7. The limit rod is fixedly connected between the connecting frames 4. A third transmission component 21 is provided between the threaded rod 6 and the connecting seat 25.

[0043] During operation, after the residual waterproof coating in the coating roller 8 below the uppermost extrusion assembly is squeezed out, the driven turntable 18 rotates again, and the coating roller 8 rotates to the rejection position. The active turntable 19 continues to rotate, driving the threaded rod 6 to rotate through the third transmission component 21. The rotation of the threaded rod 6 drives the cleaning component 7 to rotate. The cleaning component is threadedly connected to the threaded rod 6. The rotation of the threaded rod 6 drives the cleaning component to gradually move on the surface of the coating roller 8. The scraping brush on the surface of the cleaning component 7 cleans the surface of the coating roller 8. At the same time, the coating roller 8 rotates continuously during the process, thereby causing the cleaning component 7 to clean the surface of the coating roller 8 to remove the debris adhering to the wall, preventing the debris from adhering to the coating roller 8 and causing the coating roller 8 to flow towards the protrusions when coating the wall.

[0044] As a further embodiment of the present invention, a threaded column 13 is rotatably connected inside the movable frame 1, and a drive motor 3 is fixedly installed at the upper end of the threaded column 13. The output end of the drive motor 3 is fixedly connected to the threaded column 13. There are two sets of threaded columns 13 and four sets of mounting frames 9. Adjacent mounting frames 9 are kept perpendicular to each other.

[0045] During operation, the drive motor 3 rotates the electric threaded column 13, and the electric movable frame 1 moves up and down as the threaded column 13 rotates. When the movable frame 1 moves from the upper end of the threaded column 13 to the lower end of the threaded column 13, and then from the lower end of the threaded column 13 to the upper end of the threaded column 13, the inserting rod 22 of the active turntable 19 just slides into the inserting groove 24.

[0046] As a further embodiment of the present invention, a sliding groove 29 is provided on the movable frame 1, a slider 12 is slidably connected in the sliding groove 29, a toothed plate 26 is fixedly connected on the slider 12, a drive gear 27 is rotatably installed at the lower end of the movable frame 1, the drive gear 27 meshes with the toothed plate 26, a paint can 5 is fixedly installed at the lower end of the toothed plate 26, the upper end of the paint can 5 is wide-mouthed, a micro motor 28 is fixedly installed on the movable frame 1, and the output end of the micro motor 28 is fixedly connected to the drive turntable 19.

[0047] The toothed plates 26 are symmetrically arranged on the movable frame 1. The movable frame 1 is equipped with a forward and reverse motor. The output end of the forward and reverse motor meshes with the drive gear 27. There are two sets of drive gears 27. The two sets of drive gears 27 mesh with each other. One side of the drive gears 27 meshes with each other, and the other side meshes with the toothed plates 26.

[0048] During operation, the drive gear 27 rotates and meshes with the toothed plate 26. The drive gear 27 drives the teeth to move downwards, which in turn drives the paint tank 5 downwards. When the coating roller 8 reaches the bottom, the reversible motor rotates in the opposite direction, driving the drive gear 27 to rotate in the opposite direction. This rotation of the drive gear 27 drives the toothed plate 26 to move upwards, which in turn drives the paint tank 5 upwards, immersing the coating roller 8 into the paint tank 5. Then, the reversible motor rotates in the forward direction, driving the drive gear 27 to rotate in the forward direction. This rotation of the drive gear 27 drives the toothed plate 26 to move downwards, which in turn drives the paint tank 5 to the bottom. At this point, the user rotates the driven turntable 18 to replace the coating roller 8, and then the paint tank 5 moves downwards again.

[0050] Step 1: Turn on the micro motor 28 and drive motor 3. The micro motor 28 drives the active turntable 19 to rotate. The rotation of the active turntable 19 drives the coating roller 8 to rotate through the second transmission component 20 and the first transmission component 15. At the same time, the drive motor 3 drives the threaded column 13 to rotate, driving the movable frame 1 to move up and down.

[0051] Step 2: When the movable frame 1 moves from the upper end to the lower end of the threaded column 13, the insert rod of the active turntable 19 slides into the driven turntable 18, causing the driven turntable 18 to rotate. The rotation of the driven turntable 18 causes the mounting frame 9 to rotate 90 degrees.

[0052] Step 3: After the mounting bracket 9 stops rotating, the active turntable 19 continues to repeat Step 1. The forward and reverse motor drives the active gear 27 to rotate. The rotation of the active gear 27 drives the toothed plate 26 to move upward. The upward movement of the toothed plate 26 drives the paint tank 5 to move upward, so that the lower coating roller 8 is immersed in the paint tank 5.
