Description

Technical Field

[0001] This invention relates to the field of permeability testing technology, specifically a permeability testing device for slope waterproofing materials. Background Technology

[0002] Slope protection materials are functional materials used in slope engineering to block surface water infiltration and prevent groundwater seepage from eroding the slope's soil and rock. The core requirements are impermeability, conformity to the slope, aging resistance, weathering resistance, and erosion resistance. They must also be suitable for the slope's gradient, soil and rock properties, engineering scenario, and ease of construction. Based on their form, construction method, and applicable scenarios, slope protection materials are mainly divided into five categories: flexible roll materials, rigid cast-in-place materials, spray-applied materials, geosynthetic materials, and composite materials. The characteristics, applicable scenarios, and typical products of each type are as follows, covering mainstream engineering scenarios such as soil and rock slopes, roadbed slopes, hydraulic slopes, and mine spoil heap slopes. Among them, the core characteristics of flexible roll materials are: flexible texture, bendable and conformable to slope undulations, fast construction, adaptability to small slope deformations, stable impermeability, and they are mostly industrial prefabricated products.

[0003] Currently, when using testing devices to inspect the impermeability of flexible roll-type waterproofing materials, effective clamping and connection of the material is not possible. When conducting multi-area testing, the testing area needs to be changed. During the testing process, wrinkles and displacement of the material can easily lead to poor sealing of the testing area, affecting the testing results. The accuracy and efficiency of the testing are low, making it difficult to meet practical testing needs. To address these shortcomings of existing technologies, this paper provides a permeability testing device for slope waterproofing materials to solve the aforementioned problems.

A lifting frame penetrating the testing platform is vertically slidably mounted on the fixed frame. A humidity monitor is fixed to the bottom of the lifting frame. A short pipe is fixed to the bottom of the sealing conical hood. A probe of the humidity monitor extends through the short pipe into the sealing conical hood. A cleaning assembly for cleaning the probe surface is installed inside the short pipe.

[0006] As an improvement of the present invention: the lifting drive assembly includes two threaded rods coaxially fixed with the output shaft of the servo motor II, the threads of the two threaded rods having opposite directions, each threaded rod having a threaded sleeve block threadedly connected to it, and each threaded sleeve block having a traction rod hinged to the piston cylinder.

[0007] As an improvement of the present invention: a clamping plate is sleeved on the vertical pipe and located above the seepage-proof material. A supporting spring is fixed between the clamping plate and the testing platform. Several extension sleeves are fixed on the side wall of the sealing cover. A push post is slidably passed through each extension sleeve. A push plate is fixed at the lower end of the push post. A connecting spring is fixed between the push plate and the extension sleeve.

[0008] As an improvement of the present invention: the conveying assembly includes two winding rollers rotatably mounted on the detection table, the anti-seepage material is wound on the two winding rollers, and a servo motor I for driving one of the winding rollers to rotate is fixed on the detection table.

[0009] As an improvement of the present invention: the pressurization assembly includes a piston head that is sealed and slidably installed inside the piston cylinder, a piston column that extends to the outside of the piston cylinder is fixed on the piston head, the steam pipe is fixed to the piston column, the steam pipe passes through the piston column and the piston head and extends into the piston cylinder, and a check valve that is fixed on the piston column is installed on the steam pipe.

[0010] As an improvement of the present invention: the pressurization assembly further includes an externally threaded tube fixed to the top of the piston cylinder, an internally threaded sleeve rotatably sleeved on the piston rod, the internally threaded sleeve being threaded onto the externally threaded tube, the piston rod penetrating the externally threaded tube, and a locking block slidably embedded in the outer wall of the externally threaded tube being fixed to the inner wall of the piston rod.

[0011] As an improvement of the present invention: the cleaning assembly includes several L-shaped carriages that slide through the short tube, an extension seat is fixed at the bottom of the short tube, a rotating arm is rotatably mounted on the extension seat, a torsion spring is fixed between the rotating end of the rotating arm and the extension seat, and a brush clamp is fixed at one end of the L-shaped carriage located inside the short tube.

[0012] As an improvement of the present invention: a fixed plate is fixed on the probe, a sliding plate is slidably sleeved on the probe, a spring ring is fixed between the sliding plate and the fixed plate, and a push post corresponding vertically to the rotating arm is fixed on the sliding plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1.

Subsequently, the sealing cover moves downward and docks with the sealing conical cover, effectively ensuring the clamping and positioning of the seepage-proof material in the tested area. This ensures the stability of the seepage-proof material's position during the testing process. When the seepage-proof material is tested in multiple areas sequentially, the automatic clamping and positioning effect of the seepage-proof material can be achieved, greatly improving the accuracy and operational efficiency of seepage-proof material testing.

[0015] 2. During the process of the piston cylinder driving the sealing cover to dock with the sealing conical cover, the piston cylinder realizes the lifting frame driving the humidity monitor to move upward through the transmission cooperation of rack II, transmission gear and rack I, so that the detection end of the probe can automatically extend into the sealing conical cover and approach the bottom surface of the seepage prevention material to detect humidity. During this process, the probe is clamped and cleaned by the cleaning component, ensuring the accuracy of the seepage prevention detection results of the seepage prevention material.

It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention 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, and therefore should not be construed as a limitation of the present invention.

[0019] First embodiment: Please refer to the appendix Figure 1 - Appendix Figure 11A permeability testing device for slope seepage prevention materials includes a testing platform 1, on which seepage prevention material 2 is mounted via a conveying assembly. A fixing frame 5 is fixed to the testing platform 1. A sealing conical cover 15 for supporting the seepage prevention material 2 is mounted on the testing platform 1. A vertical pipe 8 is fixed to the fixing frame 5. A sealing cover 12, vertically corresponding to the sealing conical cover 15, is vertically slidably mounted inside the vertical pipe 8. A piston cylinder 10 communicating with the sealing cover 12 is fixed to the sealing cover 12. A pressurizing assembly is connected to the piston cylinder 10. An extension extending to... The steam pipe 11 inside the sealing cover 12 is fixed with a servo motor II44 on the fixed frame 5. The servo motor II44 is connected to a lifting drive assembly for driving the piston cylinder 10 to move vertically. A lifting frame 6 that passes through the detection table 1 is vertically slidably installed on the fixed frame 5. A humidity monitor 16 is fixed at the bottom of the lifting frame 6. A short pipe 34 is fixed at the bottom of the sealing conical cover 15. The probe 33 of the humidity monitor 16 extends through the short pipe 34 into the sealing conical cover 15. A cleaning assembly for cleaning the surface of the probe 33 is installed inside the short pipe 34.

[0020] When testing the impermeability of the impermeable material 2 using this device, the sealing conical cover 15 and the pressure plate 27 are joined together to clamp the impermeable material 2 between them, providing initial positioning. The connection between the sealing cover 12 and the sealing conical cover 15 ensures the sealing of the testing area of ​​the impermeable material 2, thereby ensuring the accuracy of the permeability test. Steam is injected into the piston cylinder 10 and the sealing cover 12 through the steam pipe 11, and the humidity of the bottom surface of the impermeable material 2 is measured by the probe 33 of the humidity monitor 16, thus achieving the impermeability test of the impermeable material 2.

[0021] The lifting drive assembly of this device includes two threaded rods 45 coaxially fixed to the output shaft of the servo motor II44. The threads of the two threaded rods 45 have opposite directions. Each threaded rod 45 is threadedly fitted with a threaded sleeve block 14. Each threaded sleeve block 14 is hinged to the piston cylinder 10 with a traction rod 13. A pressure plate 27 is fitted onto the vertical pipe 8 above the seepage-proof material 2. A support spring 28 is fixed between the pressure plate 27 and the detection table 1. Several extension sleeves 30 are fixed to the side wall of the sealing cover 12. A push column 24 slides through each extension sleeve 30. A push plate 26 is fixed to the lower end of the push column 24. A connecting spring 25 is fixed between the push plate 26 and the extension sleeve 30.

[0022] Servo motor II44 drives threaded rod 45 to rotate. Threaded rod 45 drives two threaded sleeve blocks 14 to move away from each other. Threaded sleeve blocks 14 pull piston cylinder 10 vertically downward via traction rod 13. Piston cylinder 10 drives sealing cover 12 vertically downward. At this time, push plate 26 moves vertically downward and pushes against pressing plate 27. Pressing plate 27 compresses support spring 28 and finally presses against waterproof material 2 and connects with the end of sealing conical cover 15. Subsequently, extension sleeve 30 moves downward relative to push column 24. Finally, the lower end of sealing cover 12 abuts against the upper surface of waterproof material 2. At the same time, the lower end of sealing cover 12 and the upper end of sealing conical cover 15 clamp waterproof material 2. The above process realizes the initial clamping and positioning of waterproof material 2 and the sealing operation of the upper surface, effectively improving the operation efficiency and accuracy of waterproof material 2 waterproofness detection.

[0023] In addition, the conveying assembly of this device includes two winding rollers 3 rotatably mounted on the testing table 1. The impermeable material 2 is wound around the two winding rollers 3. A servo motor I4 is fixed on the testing table 1 to drive one of the winding rollers 3 to rotate. The servo motor I4 can drive one of the winding rollers 3 to rotate in a stepwise manner. The winding roller 3 drives the impermeable material 2 to be conveyed and moved, which facilitates multi-area impermeability testing of the impermeable material 2.

[0024] The pressurization assembly of this device includes a piston head 32 that is slidably and sealed inside a piston cylinder 10. A piston rod 23 extending to the outside of the piston cylinder 10 is fixed to the piston head 32. A steam pipe 11 is fixed to the piston rod 23, passes through the piston rod 23 and the piston head 32, and extends into the piston cylinder 10. A check valve 21 fixed to the piston rod 23 is installed on the steam pipe 11. The pressurization assembly also includes an externally threaded pipe 20 fixed to the top of the piston cylinder 10. An internally threaded sleeve 22 is rotatably sleeved on the piston rod 23. The internally threaded sleeve 22 is threaded onto the externally threaded pipe 20. The piston rod 23 passes through the externally threaded pipe 20. A retaining block 31 that is slidably embedded in the outer wall of the piston rod 23 is fixed to the inner wall of the externally threaded pipe 20.

[0025] By screwing the internal threaded sleeve 22, it can rotate relative to the external threaded pipe 20. The internal threaded sleeve 22 also drives the piston rod 23 to slide relative to the piston cylinder 10, so that the piston head 32 can slide relative to the piston cylinder 10 toward the sealing cover 12, thereby increasing the pressure inside the sealing cover 12 and regulating the air pressure inside the sealing cover 12 to ensure accurate detection of the seepage prevention material 2.

[0026] Second embodiment: Please refer to the appendix Figure 1 - Appendix Figure 11In addition to the first embodiment, the cleaning component of this device includes several L-shaped carriages 35 that slide through the short tube 34. An extension seat 17 is fixed at the bottom of the short tube 34. A rotating arm 38 is rotatably mounted on the extension seat 17. A torsion spring 7 is fixed between the rotating end of the rotating arm 38 and the extension seat 17. A brush clamp 39 is fixed at one end of the L-shaped carriage 35 located inside the short tube 34.

[0027] Among them, a fixed plate 42 is fixed on the probe 33, a sliding plate 40 is slidably sleeved on the probe 33, a spring ring 43 is fixed between the sliding plate 40 and the fixed plate 42, and a push post 41 corresponding vertically to the rotating arm 38 is fixed on the sliding plate 40.

[0028] As the probe 33 of the humidity monitor 16 extends into the sealed conical cover 15, the push post 41 on the sliding plate 40 first pushes the rotating arm 38. The rotating arm 38 drives the pin 37 to rotate. At this time, the pin 37 slides in the vertical slot 36, causing the L-shaped slide 35 to drive the brush clamp 39 to slide towards the center of the short tube 34. Multiple brush clamps 39 abut against each other and form a circle. The inside of this circle is filled with soft bristles on the brush clamps 39. Then the probe 33 continues to move upward, and the spring ring 43 is elastically compressed. The probe 33 is cleaned by the soft bristles on the brush clamps 39, ensuring that the detection end of the probe 33 has a high degree of cleanliness when performing humidity detection, thus improving the accuracy of the anti-seepage detection.

[0029] In addition, a transmission gear 18 is rotatably mounted on the fixed frame 5. Rack I9 and rack II19 are respectively meshed on both sides of the transmission gear 18. Rack I9 is ​​fixed to the lifting frame 6, and rack II19 is fixed to the piston cylinder 10. During the downward movement of the piston cylinder 10, rack II19 moves vertically downward and drives the transmission gear 18 to rotate. The transmission gear 18 drives rack I9 upward, causing the lifting frame 6 to move the humidity monitor 16 upward. This allows the probe 33 to extend into the sealed conical cover 15 for detection. The above actions achieve a continuous process of clamping and positioning the anti-seepage material 2, extending the probe 33, and cleaning the surface, greatly improving the anti-seepage detection efficiency of the anti-seepage material 2.

[0030] In summary, this invention, through the piston cylinder 10 driving the sealing cover 12 to move vertically downward, pushes the pressing plate 27 downward via the push plate 26, thereby clamping the seepage-proof material 2 between the sealing conical cover 15 and the pressing plate 27. Subsequently, the sealing cover 12 moves downward and docks with the sealing conical cover 15, effectively ensuring the clamping and positioning of the seepage-proof material 2 in the tested area, ensuring the stability of the position of the seepage-proof material 2 during the testing process. When the seepage-proof material 2 is tested in multiple areas successively, the automatic clamping and positioning effect of the seepage-proof material 2 can be achieved, greatly improving the accuracy and operational efficiency of the seepage-proof material 2 seepage detection. During the process of the piston cylinder 10 driving the sealing cover 12 to dock with the sealing conical cover 15, the piston cylinder 10 realizes the lifting frame 6 driving the humidity monitor 16 to move upward through the transmission cooperation of rack II 19, transmission gear 18 and rack I 9, so that the detection end of the probe 33 can automatically extend into the sealing conical cover 15 and approach the bottom surface of the anti-seepage material 2 to detect humidity. During this process, the probe 33 is clamped and cleaned by the cleaning component, ensuring the accuracy of the anti-seepage detection result of the anti-seepage material 2.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
