A cleaning device for tubular joints of ultra-deep concrete cutoff walls

Abstract

This utility model relates to the field of anti-seepage wall construction technology, specifically to a cleaning device for tubular joint seams of ultra-deep concrete anti-seepage walls. It includes two opposing connecting plates with an adjustable spacing. Each connecting plate is equipped with a rotation drive mechanism and a turntable connected to the rotation drive mechanism. The turntable is equipped with brush bristles. When the turntables on the two connecting plates rotate, the brush bristles clean the tubular joint seams on both sides of the secondary foundation trench. This utility model uses two turntables to clean the tubular joint seams on both sides of the secondary foundation trench. During the cleaning process, the connecting plates adjust and maintain a suitable distance between the two turntables so that the brush bristles can closely adhere to the wall surface of the tubular joint seams. This ensures that the cleaning device does not shake within the secondary foundation trench, and the brush bristles have strong adhesion to the tubular joint seams, significantly improving the cleaning effect.

Description

Technical Field

[0001] This utility model relates to the field of anti-seepage wall construction technology, specifically to a cleaning device for tubular joint seams of ultra-deep concrete anti-seepage walls. Background Technology

[0002] Cutoff walls are a type of foundation seepage prevention structure widely used in water conservancy and civil engineering. They ensure the safety and stability of the project by blocking the seepage path of groundwater or water bodies. The construction of cutoff walls is divided into two phases: the first phase involves excavating foundation trenches and pouring concrete at intervals; the second phase involves excavating a foundation trench between two first-phase concrete walls and then pouring concrete thereafter. This process controls construction risks and improves project quality and efficiency. To enhance the seepage prevention effect between the first-phase and second-phase concrete walls, a joint pipe is inserted before pouring the first-phase concrete wall (the joint pipe is slowly pulled out using a pipe-pulling machine during the pouring process). This creates a tubular joint seam on the end face of the first-phase concrete wall. When the second-phase concrete is poured, this tubular joint seam extends the seepage path, thus increasing the seepage prevention effect. Before pouring the second-phase concrete, the tubular joint seam needs to be cleaned to remove any adhering soil, ensuring that the second-phase concrete wall can fit tightly against the first-phase concrete wall.

[0003] In existing technologies, a drilling rig is typically connected to a cleaning brush head. The drilling rig drives the brush head to rise, fall, and rotate to clean the tubular joint seams. However, when cleaning ultra-deep concrete cutoff walls (depth greater than 100m), the brush head is relatively light, and the bristles have less adhesion to the inner wall of the joint seam, resulting in poor cleaning effect. Utility Model Content

[0004] In view of this, the present invention provides a cleaning device for tubular joint seams of ultra-deep concrete cutoff walls, which aims to improve the cleaning effect on tubular joint seams of ultra-deep concrete cutoff walls.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is as follows:

[0006] A cleaning device for tubular joint seams of an ultra-deep concrete anti-seepage wall includes two oppositely arranged connecting plates with adjustable spacing; a rotation drive mechanism and a turntable connected to the rotation drive mechanism are installed on the connecting plates, and the turntable is provided with bristles; when the turntables on the two connecting plates rotate, the bristles are used to clean the tubular joint seams on both sides of the secondary foundation trench.

[0007] In some optional embodiments, a positive and negative lead screw is also included; the connecting plate is also provided with a vertical plate with a threaded hole; the positive and negative lead screw is screwed to the threaded hole of the vertical plate on the two connecting plates; when the positive and negative lead screw rotates, the two connecting plates move towards each other or away from each other.

[0008] In some alternative implementations, one of the two connecting plates is connected to a guide rod, and the other is provided with a guide groove that matches the guide rod.

[0009] In some alternative embodiments, the connecting plate is further provided with a support plate; the support plate is disposed between the connecting plate and the upright plate.

[0010] In some alternative embodiments, a nut that can rotate with the lead screw is connected to the lead screw.

[0011] In some alternative embodiments, the connecting plate is further provided with an arc-shaped plate on which rollers for contacting the tubular joint seam are mounted.

[0012] In some alternative embodiments, the rollers are provided in multiples and distributed along the curvature of the arcuate plate.

[0013] In some alternative embodiments, the arc-shaped plate is provided with a nozzle; the nozzle is connected to a water supply device via a hose and sprays water onto the tubular joint seam.

[0014] In some alternative embodiments, a flow divider is also included; the nozzles are provided in multiple portions and distributed along the curvature of the arc-shaped plate; the multiple nozzles are all connected to the hose through the flow divider.

[0015] In some alternative embodiments, the nozzle is positioned above the turntable.

[0016] In summary, compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] This invention uses two turntables to clean the tubular joint seams on both sides of the secondary foundation trench. During the cleaning process, a connecting plate adjusts and maintains a suitable distance between the two turntables so that the bristles can adhere tightly to the wall surface of the tubular joint seams. This ensures that the cleaning device described in this invention will not shake in the secondary foundation trench, and the bristles have strong adhesion to the tubular joint seams, which can significantly improve the cleaning effect.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the stated number, while "above," "below," "within," etc. are understood to include the stated number. If terms such as "first," "second," etc., are used only to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features, or implicitly specifying the order of the indicated technical features.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] like Figure 1 and Figure 2 As shown, two spaced first-stage concrete walls 200 have been poured on the foundation 100. During the second-stage construction, the foundation 100 between the two first-stage concrete walls 200 is excavated to form the second-stage foundation trench 400, and then the tubular joint seam 300 is cleaned.

[0028] like Figure 1 and Figure 2 As shown, this utility model introduces a cleaning device for tubular joint seams of ultra-deep concrete anti-seepage walls, including two horizontally arranged connecting plates 7 with adjustable spacing. A rotation drive mechanism 3 and a turntable 8, which is pulsatorically connected to the rotation drive mechanism 3, are mounted on the connecting plates 7. The turntable 8 is provided with brush bristles 9.

[0029] The rotation drive mechanism 3 can be, for example, a motor, with its shaft set vertically so that the turntable 8 and the brush bristles 9 can rotate in the vertical direction.

[0030] The turntable 8 is preferably circular, with a radius smaller than that of the tubular joint seam 300, and the bristles 9 are filled between the turntable 8 and the tubular joint seam 300.

[0031] When the turntables 8 on the two connecting plates 7 rotate, they use brushes 9 to clean the tubular joint seams 300 on both sides of the secondary foundation trench 400. For example, the turntable 8 on the left and the brushes 9 clean the tubular joint seams 300 on the left side, and the turntable 8 on the right and the brushes 9 clean the tubular joint seams 300 on the right side.

[0032] When cleaning the tubular joint seam 300, the bristles 9 should fit tightly against the wall of the tubular joint seam 300 to ensure adhesion. The bristles 9 can be made of steel wire, which can increase the service life of the bristles 9 and enhance the cleaning effect.

[0033] A lifting ring 4 can be provided on the connecting plate 7, which facilitates hoisting operations using a wire rope, thereby allowing the cleaning device described in this utility model to move up and down in the secondary foundation trench 400. Alternatively, the cleaning device can also be moved up and down in the secondary foundation trench 400 in other ways, such as by directly fixing the wire rope to the connecting plate 7.

[0034] The cleaning device described in this utility model can move stably up and down within the secondary foundation trench 400. After the bristles 9 extend into the secondary foundation trench 400 and come into contact with the tubular joint seam 300, the bristles 9 deform, thereby tightly adhering to the wall surface of the tubular joint seam 300 and improving the adhesion of the bristles 9. During cleaning, it is only necessary to control the rotation drive mechanism 3 to start, which drives the turntable 8 to rotate to begin cleaning. The wire of the rotation drive mechanism 3 (not shown in the figure) can move with the rotation drive mechanism 3, and one end of the wire is fixed in the electrical equipment located on the foundation 100.

[0035] Because this utility model uses two turntables 8 to clean the tubular joint seams 300 on both sides of the secondary foundation trench 400, and during the cleaning process, the connecting plate 7 adjusts and maintains a suitable distance between the two turntables 8 so that the bristles 9 can closely adhere to the wall surface of the tubular joint seams 300, the cleaning device described in this utility model will not shake in the secondary foundation trench 400, and the bristles 9 have strong adhesion to the tubular joint seams 300, which can significantly improve the cleaning effect.

[0036] The cleaning device of this utility model also includes a positive and negative lead screw 12. The connecting plate 7 is also provided with a vertical plate 10 with threaded holes, and the threaded holes on the two connecting plates 7 have opposite rotation directions. The positive and negative lead screw 12 is screwed into the threaded holes on the two connecting plates 7. When the positive and negative lead screw 12 rotates, the two connecting plates 7 move towards or away from each other.

[0037] By rotating the positive and negative lead screws 12, the two connecting plates 7 can be driven to move relative to each other, thereby adjusting the distance between the two turntables 8 to adjust the adhesion between the bristles 9 and the tubular joint seam 300, and also enabling this utility model to adapt to tubular joint seams 300 of different specifications.

[0038] Optionally, one of the two connecting plates 7 is connected to a guide rod 11, and the other is provided with a guide groove 16 that matches the guide rod 11. For example, one connecting plate 7 is fixedly connected to a guide rod 11 that slides with the other connecting plate 7, wherein the connecting plate 7 without the guide rod 11 is provided with a guide groove 16, and the guide rod 11 is slidably disposed in the guide groove 16. The length direction of the guide rod 11 and the guide groove 16 is parallel to the direction in which the two connecting plates 7 move towards or away from each other.

[0039] The guide rod 11, in conjunction with the positive and negative screws 12, enables the two connecting plates 7 to move stably and adjust along the length of the guide rod 11, thereby accommodating the cleaning operation of two tubular joint seams 300 with different spacing.

[0040] A nut 5 is fixedly sleeved on the positive and negative lead screw 12. For example, the nut 5 is welded to the positive and negative lead screw 12 so that it can rotate together with the positive and negative lead screw 12. Setting the nut 5 makes it easy to rotate the positive and negative lead screw 12.

[0041] A support plate 6 is also connected between the upright plate 10 and the connecting plate 7. The support plate 6 can increase the connection strength of the upright plate 10.

[0042] As an optional implementation, the connecting plate 7 is further provided with an arc-shaped plate 1, on which rollers 13 are mounted. The arc-shaped plate 1 has a similar curved shape to the tubular joint seam 300, but its size is smaller. The rollers 13 are mounted on the outer arc surface of the arc-shaped plate 1 for contact with the surface of the tubular joint seam 300. The rollers 13 have two functions: firstly, to reduce the resistance of the cleaning device described in this invention when moving up and down in the secondary foundation trench 400; and secondly, to restrict the swinging and displacement of the entire cleaning device in the secondary foundation trench 400, thereby ensuring that the bristles 9 thoroughly clean the tubular joint seam 300. Multiple rollers 13 are provided and distributed along the curvature direction of the arc-shaped plate 1 to enhance the above-mentioned functions. Furthermore, multiple rollers 13 further help to ensure that the cleaning device described in this invention can only move up and down in the secondary foundation trench 400, and cannot swing or displace within the secondary foundation trench 400.

[0043] As an optional implementation, the arc-shaped plate 1 is provided with a nozzle 2, which is connected to the water supply equipment through a hose 15 and sprays water onto the tubular joint seam 300.

[0044] Optionally, multiple nozzles 2 are installed on the curved plate 1 along the bending direction, and a diverter 14 connected to the nozzles 2 is fixedly installed on the connecting plate 7. The diverter 14 is connected to a hose 15, which is used to deliver high-pressure water. The high-pressure water flows through the diverter 14 to each nozzle 2. The nozzles 2 spray high-pressure water to rinse the tubular joint seam 300, thereby improving the cleaning effect.

[0045] Optionally, the turntable 8 is located below the connecting plate 7, and the nozzle 2 is located above the turntable 8. After the turntable 8 drives the brush bristles 9 to clean, the nozzle 2 sprays high-pressure water to further clean the inner wall of the tubular joint seam 300, improving the cleaning effect. Furthermore, the water flows downwards along the tubular joint seam 300, thereby reducing dust generated during the brush bristle 9 cleaning process. The nozzle 2 is a diffusion nozzle, allowing the sprayed water to thoroughly rinse the inner wall of the tubular joint seam 300.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
