Building waterproof materials are a sub-project that ensures the structure of the building is not invaded by water and the internal space is not harmed by water. The performance of building waterproof materials plays an important role in the entire construction project.
[0003] For example, Chinese invention CN117969371A discloses a detection device for waterproof materials in road and bridge construction. In this invention, the threaded rod rotates to drive the moving plate to move downward, which in turn drives the fixed rod and the pressing piece to move downward, so that the pressing piece moves down into the water tank to extrude the waterproof material, making the waterproof material taut. And the pressing piece is made of transparent acrylic material, and the penetration situation of the waterproof material can be observed through the pressing piece, which is convenient to check the penetration situation of the waterproof material in the taut state and improves the detection effect. At the same time, in order to facilitate understanding the penetration situation of the waterproof material, absorbent paper can be placed between the pressing piece and the waterproof material. Through the extrusion of the pressing piece, the absorbent paper is in close contact with the waterproof material, and the penetration situation of the waterproof material is observed by observing the change of the absorbent paper. This implementation specifically solves the problem of the inconvenience in detecting the penetration situation of waterproof materials in the taut state in the prior art.

Detailed implementation manners
[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.
[0020] Embodiment 1, please refer to Figures 1 to 8 , the present invention provides a technical solution: a method for detecting waterproof materials for road and bridge construction, including the following steps: Transportation of waterproof plate: Control the electric push rod 26 to contract, drive the sealing plate 10 to move upward, and place the waterproof plate 11 to be detected on the support platform 12 in the detection box 1 through the opening generated between the upward movement of the sealing plate 10 and the detection box 1. Control the electric push rod 26 to extend, drive the sealing plate 10 to move downward to reset, and seal the detection box 1 again; Fixing of waterproof plate: Turn on the motor 17, drive the gear 19 to rotate, so that the rack row 22 and the pressing plate 24 move downward, and press both ends of the waterproof plate 11 placed on the support platform 12, so that the waterproof plate 11 is in a taut state; Water is supplied into the detection box. The water pump 4 is turned on, and the water in the water tank 2 is input into the detection box 1 through a plurality of water outlets 16 on the surface of the water spraying frame 15 for permeability detection. Simulation of the vibration state during permeability detection: After the motor 17 is turned on, when the rack row 22 is fully engaged with the gear 19, as the gear 19 continues to rotate, it drives the tooth 30 and the moving block 27 to move reciprocally. Under the action of the elastic potential energy of the second spring 38, it drives the knocking block 40 to knock the waterproof board 11 reciprocally, causing vibrations on the surface of the waterproof board 11 to simulate the vibrations that the road bridge will receive during use. Simulation of the water disturbance state during permeability detection: After the motor 17 is turned on, with the reciprocating movement of the tooth 30 and the moving block 27, the connecting rod two 28 drives the moving rod 41 to move reciprocally, and the moving column 48 slides relatively with the moving plate 47 in the sliding groove 46, driving the disturbance rod 49 to move reciprocally in the horizontal direction to disturb the detection water above the waterproof board 11, simulating the complex and changeable water flow conditions on the road and bridge during heavy rain. Recording of the detection results: After the water supply ends and it is left standing for a period of time, the liquid level height in the water storage tank 13 is observed through the observation window 6, and the accurate liquid level height is read through the scale 7 for recording. Removing the waterproof board: The first solenoid valve 9 and the second solenoid valve are turned on to drain the detection water above and below the waterproof board 11. The electric push rod 26 is controlled to contract again to open the seal between the sealing plate 10 and the detection box 1, and the waterproof board 11 after the permeability detection is taken out.
[0021] It should be noted that in the detection method for waterproof materials in road and bridge construction, the detection box 1 is adopted. The support platform 12 is fixedly installed on the inner wall of the detection box 1, the electric push rod 26 is fixedly installed on the inner wall of the detection box 1, the output end of the electric push rod 26 is fixedly installed with a first connecting block 25, the sealing plate 10 is fixedly connected to the first connecting block 25, a water storage tank 13 is opened at the bottom of the detection box 1, and a limiting surface 42 is opened in the detection box 1. A fixing component, a knocking component, and a disturbing component are arranged in the detection box 1.
[0022] The fixing component includes a cavity opened on the inner wall of the detection box 1. The motor 17 is fixedly installed on the inner wall of the cavity, the output shaft of the motor 17 is fixedly connected with a rotating shaft 18, and the gear 19 is fixedly connected to the surface of the rotating shaft 18. A first rectangular notch 20 is opened on the inner wall of the detection box 1. Two sliders 21 are slidably connected to the inner wall of the first rectangular notch 20. The rack row 22 is fixedly connected to the two sliders 21. A fixing rod is fixedly connected to the surface of the rack row 22, and the pressing plate 24 is fixedly installed at the end of the fixing rod.
[0023] Both the water tank 2 and the water pump 4 are arranged on the upper surface of the detection box 1. The surface of the water pump 4 is fixedly communicated with a water inlet pipe 3 and a water outlet pipe 14. The water spraying frame 15 is fixedly communicated with the end of the water outlet pipe 14. A plurality of water outlet holes 16 are evenly arranged on the surface of the water spraying frame 15.
[0024] A control panel 5 is arranged on the surface of the detection box 1. The surface of the sealing plate 10 is fixedly communicated with a first drain pipe 8. An electromagnetic valve 9 is arranged on the surface of the first drain pipe 8. A second drain pipe is fixedly communicated with the surface of the detection box 1. An electromagnetic valve 2 is arranged on the surface of the second drain pipe; An observation window 6 is arranged on the surface of the detection box 1. A scale 7 is arranged on the surface of the observation window 6.
[0025] More specifically, when this embodiment is in use: As Figure 2 and Figure 5 shown, control the electric push rod 26 to contract, drive the sealing plate 10 to move upward, and place the waterproof plate 11 to be detected through the opening generated between the upward movement of the sealing plate 10 and the detection box 1 on the two support platforms 12 in the detection box 1. Since the size of the waterproof plate 11 is adapted to the bottom of the inner wall of the detection box 1.
[0026] After the waterproof plate 11 is placed on the support platform 12, control the electric push rod 26 to extend again, drive the sealing plate 10 to move downward to reset, and the detection box 1 can be sealed again.
[0027] Then, start the motor 17, drive the rotating shaft 18 and the gear 19 to rotate. Under the meshing action of the gear 19 and the rack row 22, drive the rack row 22 and the pressing plate 24 to move downward until the pressing plate 24 moves downward to the position where it abuts against the upper surface of the waterproof plate 11, and the rack row 22 just finishes meshing with the gear 19, that is Figure 4 the state shown. At this time, under the action of the gravity of the two pressing plates 24 and the rack row 22, the two ends of the waterproof plate 11 placed on the support platform 12 can be pressed tightly, so that the waterproof plate 11 is in a taut state.
[0028] Then, as Figure 2 and Figure 3 shown, start the water pump 4, discharge the water in the water tank 2 through the water outlet pipe 14 into the water spraying frame 15, and then discharge it from the plurality of water outlet holes 16 on the surface of the water spraying frame 15 onto the lower waterproof plate 11 for permeability detection. It should be noted that when the detection water is conveyed into the detection box 1 for permeability detection, the liquid level height of the detection water will never be higher than the limiting surface 42.
[0029] After the water supply is completed and left standing for a while, the test water that seeps down from the waterproof board 11 will flow to the position between the lower surface of the waterproof board 11 and the inner wall of the test box 1, and will slide along the inner wall of the test box 1 into the water storage tank 13. The tester only needs to observe the liquid level height in the water storage tank 13 through the observation window 6 and read the accurate liquid level height through the scale 7, so as to judge whether the permeability test of the waterproof board 11 is qualified.
[0030] It should be noted that when performing the permeability test of the waterproof board 11, under the action of the gravity of the two pressing plates 24 and the rack row 22, both ends of the waterproof board 11 on the support table 12 are in a compressed state, thus avoiding the problem that the uneven force on the waterproof board 11 in the relaxed state may affect the accuracy of the test results, reducing the test error caused by material relaxation, and improving the reliability of the test data.
[0031] Embodiment 2, based on the above embodiment: Furthermore, the knocking component in Embodiment 1 is disclosed as follows. The knocking component includes a connecting rod 32 fixedly connected to the upper surface of the rack row 22. The connecting rod 32 penetrates through the moving block 27 and is slidably connected thereto. A stop block 31 is fixedly installed at the end of the connecting rod 32. A spring 33 is arranged between the moving block 27 and the rack row 22. Teeth 30 are fixedly connected to the surface of the moving block 27; A connecting rod 28 is fixedly connected to the surface of the moving block 27. A rectangular notch 29 for the connecting rod 28 to slide and fit is formed in the inner wall of the test box 1.
[0032] A limiting rod 39 is fixedly connected to the lower surface of the support table 12. An abutting plate 37 is slidably connected to the surface of the limiting rod 39. A rectangular notch 36 for the abutting plate 37 to slide and fit is formed in the inner wall of the test box 1. A spring 38 is arranged between the abutting plate 37 and the support table 12. A connecting rod 3 is fixedly connected to the surface of the abutting plate 37. A knocking block 40 is installed at the end of the connecting rod 3.
[0033] More specifically, when this embodiment is in use: As Figure 5 and Figure 6 shown, after the motor 17 is started, as the gear 19 rotates, when the rack row 22 is fully meshed with the gear 19, as the gear 19 continues to rotate, it will be meshed with the teeth 30 on the surface of the moving block 27 and drive the teeth 30 and the moving block 27 to move downward. At the same time, the spring 33 will also be compressed. When the gear 19 is disengaged from the teeth 30, under the action of the elastic potential energy of the spring 33, it will drive the teeth 30 and the moving block 27 to move upward and reset and mesh with the gear 19 again.
[0034] That is, after the rack row 22 is just engaged with the gear 19, as the gear 19 continues to rotate, the teeth 30 and the moving block 27 will perform reciprocating movement in the vertical direction.
[0035] As Figure 7 shown, the second spring 38 is in a compressed state in this state. As the moving block 27 reciprocates, it will drive the second connecting rod 28 to reciprocate synchronously. When the second connecting rod 28 moves downward, it will drive the abutting plate 37 to move downward and stretch the second spring 38. When the second connecting rod 28 moves upward and resets, under the action of the elastic potential energy of the second spring 38, it will drive the third connecting rod and the knocking block 40 to move upward, thereby knocking the waterproof board 11 once. The surface of the waterproof board 11 being knocked will generate vibrations, so that while the waterproof board 11 is undergoing permeability testing, it can simulate the vibration conditions caused by various factors such as vehicle passage and wind force during the use of road bridges.
[0036] Since traditional static permeability tests are difficult to comprehensively reflect the performance of materials in actual use, after adding the vibration factor, potential defects of materials under dynamic stress can be detected, thereby more comprehensively evaluating the waterproof efficiency of the waterproof board 11. This dynamic simulation environment helps to evaluate the durability and waterproof performance of waterproof materials under vibration conditions and is worthy of popularization and use.
[0037] Embodiment 3, based on the above embodiment: Furthermore, the perturbation component in Embodiment 1 is disclosed as follows. The perturbation component includes a support plate 43 fixedly connected to the surface of the rack row 22. A second limiting rod 50 is fixedly connected to the surface of the support plate 43. A second connecting block 45 is slidably connected to the surface of the second limiting rod 50. The moving plate 47 is fixedly connected to the second connecting block 45. A third spring 44 is jointly provided between the second connecting block 45 and the support plate 43. The perturbation rod 49 is fixedly installed on the surface of the moving plate 47. The moving rod 41 is fixedly connected to the surface of the second connecting rod 28. The moving column 48 is fixedly installed at the end of the moving rod 41. A sliding groove 46 for the moving column 48 to extend and slide is formed on the surface of the moving plate 47.
[0038] More specifically, when this embodiment is in use: As Figure 7 and Figure 8As shown, when the rack row 22 is fully engaged with the gear 19, as the gear 19 continues to rotate, while the tooth 30 and the moving block 27 perform reciprocating movements in the vertical direction, the reciprocating movement of the connecting rod two 28 will also drive the moving rod 41 to synchronously perform reciprocating movements in the vertical direction. As the moving rod 41 moves, the moving column 48 will slide relative to the moving plate 47 in the chute 46. Since the moving plate 47 is limited by the limiting rod two 50 and can only move horizontally at this time, as the moving column 48 slides relative to the moving plate 47 in the chute 46, it will drive the moving plate 47 to perform reciprocating movements in the horizontal direction, so that the two disturbing rods 49 on the surface of the moving plate 47 can perform reciprocating movements in the horizontal direction, so as to be able to disturb the detection water above the waterproof sheet 11 while detecting the permeability of the waterproof sheet 11, so as to simulate the complex and changeable water flow conditions in the actual environment suffered on roads or bridges during heavy rain weather, so as to be able to detect the permeability of the waterproof sheet 11 under different water flow speeds and pressures, making the detection results closer to the actual use scenario and the detection accuracy higher.
[0039] After the permeability detection of the waterproof sheet 11 in the detection box 1 is completed, turn on the solenoid valve one 9 and the solenoid valve two, and the detection water above and below the waterproof sheet 11 can be discharged. Then, control the electric push rod 26 to contract again, open the seal between the sealing plate 10 and the detection box 1, and the waterproof sheet 11 after the permeability detection can be taken out.
[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
