Description

Technical Field

[0001] The present invention relates to the technical field of road detection, and in particular to a road surface penetration detection device and method for road construction. Background Art

[0002] When testing the pavement penetration, it is necessary to place the plastic ring in the center of the test piece or at the measuring point on the pavement surface, and use chalk to draw circles along the inside and outside of the plastic ring. The part between the outer ring and the inner ring is the area that needs to be sealed with sealing materials. Use sealing materials to seal the annular sealing area. Apply a thin layer of sealing material along the circle of the base on the pavement, and press it with your hands while applying it, so that the sealing material fills the gaps and is firmly bonded to the pavement. The inner diameter of the sealing material circle is the same as the inner diameter of the base, about 150mm. Press the assembled water seepage tester base hard on the pavement sealing material circle, and then add a heavy iron ring to press the instrument base.

[0003] For example, the patent document with publication number CN118376557B is entitled a road surface penetration detection device and method for road construction, comprising a base, wherein the bottom end surface of the base is provided with an inner ring for water penetration, the outer ring of the inner ring is provided with a closed inner ring plate, the outer ring of the bottom end of the base is provided with an outer closed ring, a cavity for molding a sealing material is formed between the closed inner ring plate and the outer closed ring, the cavity is formed by the closed inner ring plate and the outer closed ring, and is used for rapid and accurate molding of the sealing material, which is convenient for improving the efficiency of the preliminary work, and contacts the sealing material through the two-layer structure, thereby increasing the sealing between the sealing material and the equipment, and adjusting the driving direction through the rotation of the gear set, so that the extrusion ring stops extruding and at the same time drives the compaction ring to compact the sealing material, thereby ensuring the sealing of the sealing material to the closed inner ring plate, the outer closed ring and the ground, and improving the overall detection accuracy.

[0004] The above-mentioned pavement penetration detection device for road construction needs to be filled with waterproof material and sealed in advance for penetration detection. Due to the different porosity of the road surface and the different degree of compaction of the road surface after it is opened to traffic, the detection results are difficult to fully reflect the changes in the permeability characteristics of the road surface in different time periods. The above-mentioned pavement penetration detection device only provides one detection method for monitoring at the same location. When encountering areas with large local pores or poor sealing, it is impossible to further detect the pavement penetration according to the actual use of the road.

When the plug ball inside the measuring cylinder mechanism blocks the leaking ball shell and no water flows out, or when the timing exceeds three minutes and the water inside the measuring cylinder mechanism is still slowly decreasing, record the data and close the valve; S3. Then the user installs the pressure water injection mechanism on the pressurizing mechanism, fills the inside of the pressure water injection mechanism with water, and then pressurizes the water inside the pressure water injection mechanism to detect the penetration of the road surface during road construction according to different pressures.

[0016] In summary, the technical effects and advantages of the present invention are as follows: 1. The present invention can more clearly understand the changes in the permeability characteristics of the road surface in different time periods through comparative analysis of the results of two tests, helping technicians to make more accurate assessments. If there are significant differences between the two test results, it can help identify potential problem points, such as areas with large local pores or poor sealing. Different test conditions may be required for certain special sections or materials. By replacing the measuring cylinder and adjusting the pressure, the test parameters can be optimized according to the specific situation. If the first test fails to achieve the expected results, the test can be continued by replacing the measuring cylinder without having to reset the entire device, saving measurement time and enabling the device to adapt to different road conditions.

[0017] 2. When the first measuring cylinder provided in the present invention is used for testing, when the water level drops to the set one hundred milliliters, the float sheet no longer provides buoyancy to the plug ball, so that the plug ball falls and blocks the water outlet of the leaking ball shell, automatically stopping the water flow; when the water level drops to one hundred milliliters, the plug ball automatically blocks the water outlet of the leaking ball shell due to loss of buoyancy, thereby simplifying the operation process, providing a reliable termination condition, and ensuring the consistency of the test results.

[0018] 3. When the inflatable ring provided by the present invention is subjected to pressure exerted by the spacer and the counterweight, the gas is discharged into the extrusion ring through the vent pipe. As the gas is filled, the extrusion ring deforms downward, further increasing the pressure on the rubber ring sleeve, so that the hydrogel can better fill the pores. Depending on the size of the road surface pores, the degree of deformation of the rubber ring sleeve is different, which in turn affects the amount of hydrogel entering the pores. By observing the sliding distance of the spacer on the measuring rod, the amount of hydrogel inside the rubber ring sleeve that enters the road surface pores can be directly reflected, thereby indirectly measuring the total pore volume. The scale marks on the measuring rod provide an intuitive way to read data, so that the inspection personnel can quickly obtain information about the volume content of the road surface pores.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1, Reference Figures 1 to 20 A road surface penetration detection device for road construction shown in the figure comprises a pressurizing mechanism 2, a water pressure adjustment mechanism is arranged at the upper end of the pressurizing mechanism 2, a pressurizing mechanism 3 is arranged inside the pressurizing mechanism 2, and a pore filling mechanism 4 for filling the gaps in the road surface and detecting the volume of the pores in the road surface is arranged at the bottom of the pressurizing mechanism 3; It is worth mentioning that the road construction pavement penetration test needs to be carried out on the road surface where the tires of the driving lanes frequently roll over the road surface for testing. After the road surface needs to be cleaned and tidy, the pore filling mechanism 4 is installed at the position where measurement is required, and then the pressure mechanism 3 at the bottom of the pressurizing mechanism 2 is connected to the pore filling mechanism 4, and then the interior of the water pressure adjustment mechanism is filled with water, and then the internal control valve of the pressurizing mechanism 2 is opened. When water flows out of the water valve 24, the control valve is closed, and then the interior of the water pressure adjustment mechanism is filled with water again, and then the water valve 24 is closed. The inspector will start timing while opening the control valve. When the plug ball 18 inside the water pressure adjustment mechanism blocks the leaking ball shell 12 and no water flows out, or when the timing exceeds three minutes and the water inside the measuring cylinder mechanism 1 is still slowly decreasing, the valve is closed after recording the data.

[0024] The pressurizing mechanism 2 includes a base 23, and a concave groove is provided at the bottom of the base 23. Fig.13The cone shape shown in the figure, the upper end of the base 23 is provided with four measuring rods 29 distributed in a circular array, the upper part of the outer surface of the four measuring rods 29 is provided with a mounting tube 26, the outer surface of the mounting tube 26 is provided with a second sealing ring 25, and the outer surface of the four measuring rods 29 is slidably mounted with a spacer 28, and the spacer 28 is located between the mounting plate 22 and the base 23; A retaining ring groove 211 is provided on the outer surface of the base 23, a water valve 24 extending into the recessed groove is provided at the upper end of the base 23, a connecting pipe 212 is provided at the lower end of the mounting pipe 26, the connecting pipe 212 passes through the base 23 and extends into the recessed groove, a notch 27 is provided at the upper end of the mounting plate 22, and a counterweight block 21 is provided at the upper end of the spacer 28.

[0025] A valve stem 215 is rotatably mounted inside the mounting tube 26 , and a valve ball 214 for controlling the communication state of the second sealing ring 25 is disposed on the outer surface of the valve stem 215 .

[0026] When in use, the valve stem 215 is rotated to drive the valve ball 214 to rotate, and the design position of the valve ball 214 is shown in the ring shell 14, and a leakage hole is opened on the surface of the valve ball 214. When the valve ball 214 rotates, the connection state of the connecting pipe 212 can be controlled through the leakage hole.

[0027] Embodiment 2: Based on the pressure-applying mechanism 3 and the pore-filling mechanism 4 proposed in Embodiment 1, this embodiment provides a further technical solution for the pressure-applying mechanism 3 and the pore-filling mechanism 4.

[0028] The pore filling mechanism 4 includes a rubber ring sleeve 44, an inner tube ring 42 and a gravity ring 41. The upper end of the rubber ring sleeve 44 is provided with a plurality of shaping sheets 43 distributed in a ring array. The inner wall of the rubber ring sleeve 44 is provided with an inner ring edge 46. The outer surface of the rubber ring sleeve 44 is provided with an outer ring edge 47. The inner tube ring 42 is squeezed on the upper surface of the inner ring edge 46, and the gravity ring 41 is squeezed on the upper surface of the outer ring edge 47.

[0029] The diameter of the rubber ring sleeve 44 is the same as that of the extrusion ring 33 , and the shaping sheet 43 is tightly attached to the lower surface of the extrusion ring 33 . A plurality of rubber tubes 45 distributed in a circular array are arranged at the bottom of the rubber ring sleeve 44 .

[0030] It is worth mentioning that when in use, the hydrogel is filled in the rubber ring sleeve 44, and the rubber tube 45 is used to maintain the shape of the rubber ring sleeve 44 to prevent collapse, and then the rubber ring sleeve 44 is covered on the road surface that needs to be inspected, and the inner tube ring 42 is pressed on the inner ring edge 46, and then the gravity ring 41 is pressed on the outer ring edge 47. The gravity ring 41 and the inner tube ring 42 are provided to shape the rubber ring sleeve 44 and seal the hydrogel inside the rubber ring sleeve 44 to prevent side leakage.

[0031] The pressure-applying mechanism 3 includes an air-filling ring 31 . The air-filling ring 31 is in a circular ring shape and is located between the spacer 28 and the base 23 .

[0032] The inflatable ring 31 is sleeved on the outer surface of the second sealing ring 25, a locking ring 35 is arranged inside the retaining ring groove 211, an extrusion ring 33 is arranged on the outer surface of the locking ring 35, and a plurality of ventilation pipes 32 are arranged between the inflatable ring 31 and the extrusion ring 33. The ventilation pipes 32 are used to connect the air inside the extrusion ring 33 and the inflatable ring 31.

[0033] It is worth noting that when in use, the extrusion ring 33 is aligned with the rubber ring sleeve 44, and then the extrusion ring 33 is sleeved on the outer surface of the inner tube ring 42. When in use, after the inflatable ring 31 is pressed by the spacer 28 and the counterweight 21, the gas inside the inflatable ring 31 is discharged into the extrusion ring 33 through the vent pipe 32, and the extrusion ring 33 is filled with slow gas and deformed downward to squeeze the rubber ring sleeve 44; The rubber ring 44 is deformed after being squeezed, and the shaping piece 43 is set to make the upper part of the rubber ring 44 evenly receive the squeezing force. When the rubber ring 44 is squeezed, the hydrogel inside is squeezed into the pores on the roadside. When the pores of the road surface are larger, more hydrogel is squeezed into the pores through the rubber ring 44. When the pores of the road surface are smaller, the deformation of the rubber ring 44 is smaller, so that when the counterweight block 21 applies pressure to the spacer 28, the sliding distance of the spacer 28 on the outer surface of the measuring rod 29 is smaller. The total volume of the pores can be obtained by the amount of water entering the pores of the road surface through the rubber ring 44. The approximate volume content of the pores in the road surface can be detected by observing the scale of the small sliding of the spacer 28 on the measuring rod 29.

[0034] The hydrogel not only seals but also adapts to and fills tiny gaps on the road surface to ensure that the test area is completely closed. The rubber tube 45 maintains its shape to prevent the rubber ring 44 from collapsing during pressure application, thereby maintaining its original shape and ensuring uniform pressure distribution.

[0035] The gravity ring 41 and the inner tube ring 42 shape the rubber ring sleeve 44 and ensure that the hydrogel inside is effectively sealed to prevent side leakage, so that the upper part of the rubber ring sleeve 44 is evenly squeezed, ensuring that the hydrogel can evenly enter the road surface gap, thereby improving the measurement accuracy.

[0036] When the inflation ring 31 is subjected to pressure from the spacer 28 and the counterweight 21, gas is discharged into the extrusion ring 33 through the vent pipe 32. As the gas is filled, the extrusion ring 33 is deformed downward, further increasing the pressure on the rubber ring sleeve 44, so that the hydrogel can better fill the pores. Depending on the size of the pores in the road surface, the degree of deformation of the rubber ring sleeve 44 is different, which in turn affects the amount of hydrogel entering the pores.

[0037] By observing the sliding distance of the spacer 28 on the measuring rod 29, the amount of hydrogel inside the rubber ring sleeve 44 entering the pavement pores can be directly reflected, thereby indirectly measuring the total pore volume. The scale marks on the measuring rod 29 provide an intuitive data reading method, allowing the inspector to quickly obtain information about the pavement pore volume content.

[0038] Embodiment 3: This embodiment provides a specific technical solution for the measuring cylinder mechanism 1 in the water pressure adjustment mechanism.

[0039] The water pressure adjustment mechanism includes a measuring cylinder mechanism 1, which includes a first measuring cylinder 11. A first sealing ring 13 is provided at the bottom of the inner wall of the first measuring cylinder 11, an annular shell 14 is provided at the lower part of the inner wall of the first measuring cylinder 11, a water leaking spherical shell 12 is provided at the lower end of the annular shell 14, a mounting cover 17 is provided on the inner wall of the annular shell 14, a first support rod 16 is slidably installed inside the mounting cover 17, a plug ball 18 for sealing the water leaking spherical shell 12 is provided at the lower end of the first support rod 16, a floating plate 15 for providing buoyancy to adjust the position height of the plug ball 18 is provided at the upper end of the first support rod 16, and the first measuring cylinder 11 is mounted on the outer surface of the floating plate 15 through the first sealing ring 13.

[0040] It is worth noting that, when in use, the first measuring cylinder 11 is installed on the mounting tube 26, and the second sealing ring 25 and the first sealing ring 13 can further seal the installed first measuring cylinder 11, and the relative sealing of the first sealing ring 13 and the second sealing ring 25 increases the sealing performance of the first measuring cylinder 11. When in use, the first measuring cylinder 11 is filled with water, and the road surface is tested for water penetration. The valve ball 214 is opened, and the water level inside the first measuring cylinder 11 slowly drops. When the water level inside the first measuring cylinder 11 drops to 100 milliliters, the floating sheet 15 will be exposed on the water. At this time, the plugging ball 18 falls to the bottom of the leaking ball shell 12 because there is no buoyancy provided by the floating sheet 15. The plugging ball 18 blocks the water outlet of the leaking ball shell 12 to prevent the accelerated decline of the first measuring cylinder 11. The test personnel can detect the pavement permeability for road construction according to the time taken for the water inside the first measuring cylinder 11 to drop to 100 milliliters.

[0041] Among them, as the water level drops, the floating sheet 15 is gradually exposed above the water. When the water level drops to the set one hundred milliliters, the floating sheet 15 no longer provides buoyancy to the plug ball 18, so that the plug ball 18 falls and blocks the water outlet of the leaking ball shell 12, automatically stopping the water flow. When the water level drops to one hundred milliliters, the plug ball 18 automatically blocks the water outlet of the leaking ball shell 12 due to the loss of buoyancy, which simplifies the operation process, provides a reliable termination condition, and ensures the consistency of the test results.

[0042] The inspector can detect the permeability of the road surface for road construction according to the time taken for the water inside the first measuring cylinder 11 to drop to one hundred milliliters. The time-based measurement method is simple and intuitive, and is convenient for obtaining results quickly.

[0043] Embodiment 4: This embodiment provides a specific technical solution for the pressure-applying water injection mechanism 5 in the water pressure adjustment mechanism.

[0044] The water pressure adjustment mechanism includes a pressure-applying water injection mechanism 5, which includes a second measuring cylinder 51. A support cover 52 is provided on the outer surface of the second measuring cylinder 51, and a rubber ring 53 is provided on the bottom of the outer surface of the second measuring cylinder 51. The second measuring cylinder 51 is installed inside the mounting tube 26 through the rubber ring 53, and the support cover 52 is located at the upper end of the mounting plate 22.

[0045] It is worth noting that when conducting penetration testing on the road surface for road construction, when the first measuring cylinder 11 is filled with water but its position drops slowly or the current water level is maintained for three minutes, the first measuring cylinder 11 is removed from the mounting tube 26, and then the second measuring cylinder 51 is inserted into the interior of the mounting tube 26, and the provided rubber ring 53 is used to seal the installation of the second measuring cylinder 51.

[0046] The inner wall of the second measuring cylinder 51 is provided with a guide sliding block 54, the middle part of the inner wall of the second measuring cylinder 51 is provided with a second supporting rod 55, the outer surface of the second supporting rod 55 is provided with a sealing sleeve 58, the outer surface of the sealing sleeve 58 is provided with a push block 56, the push block 56 is slidably installed inside the second measuring cylinder 51 through the guide sliding block 54, and the upper end of the push block 56 is provided with a pressure block 57.

[0047] Among them, when testing the pavement penetration for road construction, fill the second measuring cylinder 51 with water, then put the push block 56 on the second support rod 55, and the guide slider 54 assists the push block 56 to continue to slide downward, and the provided sealing sleeve 58 can provide better sealing performance, then open the valve ball 214 and put the pressure block 57 into the upper part of the push block 56, and then observe the water level inside the second measuring cylinder 51, and apply different pressures to the water inside the second measuring cylinder 51 by continuously adding the pressure block 57, so as to observe the water level inside the second measuring cylinder 51 to detect the penetration of the pavement for road construction.

[0048] Among them, when the water level inside the first measuring cylinder 11 drops slowly or maintains the current water level for three minutes, it indicates that the road surface has a low permeability or good sealing. This preliminary test helps to confirm the basic condition of the road surface. By continuously increasing the number of pressure blocks 57, different pressures can be applied to the water inside the second measuring cylinder 51 to simulate different pressure conditions under actual traffic load conditions. The method of gradually increasing the pressure can more comprehensively evaluate the permeability characteristics of the road surface under different pressures.

[0049] The permeability of the road surface can be monitored in real time by observing the water level changes inside the second measuring cylinder 51. After each addition of the pressure block 57, the corresponding water level changes are recorded to facilitate subsequent data analysis. Combined with the time record, specific data on the permeability rate can be obtained, providing a basis for evaluating the waterproof performance of the road surface.

[0050] By comparing and analyzing the results of the two tests, we can more clearly understand the changes in the permeability characteristics of the road surface in different time periods, helping technicians make more accurate assessments. If there are significant differences between the two test results, it can help identify potential problem points, such as large local pores or poorly sealed areas. Different test conditions may be required for certain special sections or materials. By replacing the measuring cylinder and adjusting the pressure, the test parameters can be optimized according to the specific situation. If the first test does not achieve the expected results, the test can be continued by replacing the measuring cylinder without having to reset the entire device, saving measurement time and making the device adaptable to different road conditions.

[0051] The present invention also provides a method for using a road surface penetration detection device for road construction. The specific method for using the road surface penetration detection device for road construction is as follows: S1. Road construction pavement penetration testing requires that tires on the roadway frequently roll over the pavement for testing. The measuring cylinder mechanism 1 is installed on the pressurizing mechanism 2, and then the inside of the pore filling mechanism 4 is filled with hydrogel, and then the pore filling mechanism 4 is placed on the road surface to be tested; S2, dock the pressure mechanism 3 at the bottom of the pressure mechanism 2 to the pore filling mechanism 4, then fill the measuring cylinder mechanism 1 with water, then open the internal control valve of the pressure mechanism 2, close the control valve when water flows out from the water valve 24, then fill the measuring cylinder mechanism 1 with water again, then close the water valve 24, and the inspector will start timing while opening the control valve.
