Description

Technical Field

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

[0002] The strength of a highway pavement is an important indicator for evaluating its quality and safety. Through strength testing, we can understand various key information about the pavement and promptly discover potential quality problems, such as cracks, sanding, and peeling. If these problems are not handled in a timely manner, they may cause pavement damage, deformation, and even traffic accidents. Therefore, strength testing is of great significance to ensuring road safety and quality. Through testing, we can understand whether the construction quality of the pavement meets the design requirements and provide a basis for subsequent maintenance and management. Regular strength testing can also promptly discover the damage to the pavement, so as to take targeted maintenance measures to avoid further damage to the pavement and extend the service life of the pavement.

[0003] With the improvement of environmental awareness and the development of technology, recycled pavement technology has received more and more attention due to its economy and environmental friendliness. Recycled materials can not only reduce the consumption of natural resources, but also effectively treat waste and reduce environmental pollution. However, the performance stability of recycled materials is often not as good as that of new materials, which brings challenges to the construction of recycled pavements. Recycled pavement materials have diverse sources. For example, through recycled asphalt concrete technology, abandoned asphalt pavements can be recycled into new pavement materials; recycled concrete technology can recycle old concrete pavements; at the same time, some new materials and processes have been introduced into pavement recycling technology, such as rubber crushing materials, recycled polymer materials, etc. Therefore, the inclusion of different proportions of new and old materials leads to large differences in their physical and chemical properties. The uncertainty of this material property increases the difficulty of pavement design and construction, and also makes the detection of pavement strength more important.

[0004] However, the traditional detection method is relatively simple, that is, using a drop weight deflectometer to detect the bearing capacity and structural integrity, which is difficult to fully and accurately evaluate the condition of the regenerated pavement. In addition, the regenerated pavement has certain particularities compared to conventional pavements, so it needs to be tested more specifically. Summary of the invention

[0050] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0051] like Figure 1-10 As shown, a regenerated road surface strength detection device comprises: a tractor trailer 1 and a frame 2, a first base 3, a semi-enclosed platform 4 and a second base 5 which are sequentially installed on the tractor trailer 1 from front to back, a plurality of flanges 6 which are integrally connected to the outer wall of the frame 2, and a plurality of flanges 6 are movably installed on the semi-enclosed platform 4, two sets of drive components 7 which are arranged on the first base 3 and the frame 2, and the two sets of drive components 7 are arranged in a mirror image, a circulating flushing part 8 which is arranged on the frame 2, the semi-enclosed platform 4 and the second base 5, and a heavy pressure and rapid grinding part 9 which is installed on the frame 2. In actual use, the tractor trailer 1 can be towed by a pickup truck or other vehicle to facilitate flexible movement to different areas to be detected, a mobile power supply is arranged on the tractor trailer 1, and each component which needs electricity is connected to it to ensure the normal operation of the regenerated road surface strength detection device, wherein:

[0052] Driving the two groups of driving components 7 can synchronously generate vertical driving force to jointly gradually lower the frame 2 onto the external road surface;

[0053] Starting the circulating flushing unit 8 can use a strong water flow to circulate and flush the external road surface in the frame 2, so that the external road surface is subjected to continuous hydraulic impact;

[0054] The heavy pressure and fast grinding part 9 is suitable for statically pressing down or quickly rubbing the external road surface to apply strong external force to the external road surface. The regenerated road surface strength detection device can automatically and stably place the frame 2 on the road surface to be detected after reaching the designated detection location under the cooperation of two sets of driving components 7, a plurality of convex edges 6 and a semi-enclosed platform 4, so that the frame 2 is used to frame the area to be detected on the road surface to form a detection interval relatively isolated from the inside and outside for various subsequent detections. The circulating flushing part 8 can generate a strong water flow to continuously and cyclically flush the road surface in the interval framed by the frame 2, thereby simulating a water erosion environment, and then testing the road surface's ability to resist rainwater erosion. The circulating flushing part 8 can continuously heat the water at the same time, thereby raising the water temperature, and using water with a certain temperature to flush the road surface, thereby Different environmental conditions are simulated to verify the condition of the road surface at different temperatures, to ensure its stability and durability under different climatic conditions. The heavy pressure and rapid grinding part 9 can generate pressure to apply pressure to the road surface, thereby simulating the effect of vehicle load to detect the compressive strength of the road surface to evaluate its bearing capacity. At the same time, the heavy pressure and rapid grinding part 9 can also use two different instruments to quickly rub the road surface to detect the ability of the road surface to resist wear. The regenerated road surface strength detection device can perform a series of complete detection methods according to the particularity of the regenerated road surface. The detection methods can be flexibly combined to carry out targeted and comprehensive detection of the road surface, thereby ensuring that the condition of the regenerated road surface can be comprehensively and accurately evaluated, and then ensuring that the overall strength of the regenerated road surface can be mastered to evaluate its safety, and ensure timely maintenance and repair.

[0055] Optionally, the circulating flushing part 8 includes a water reservoir 81 and a first water pump 82 arranged on the second base 5, and the water inlet of the first water pump 82 is connected to the water reservoir 81 from one side, a drainage channel 83 is installed at the bottom of the inner wall of the frame 2, the end of the drainage channel 83 is inclined downward, one end is connected to the drainage channel 83, and the other end is connected to the water outlet of the first water pump 82. A water-absorbing cotton block 85 is installed at the bottom of the inner wall of the frame 2, and the water-absorbing cotton block 85 is located on the opposite side of the drainage channel 83. A second water pump 86 is arranged on the second base 5 in parallel with the first water pump 82, and the water outlet of the second water pump 86 is connected to the water reservoir 81 from the other side, and a water pump 87 with one end inserted into the water absorbent cotton block 85 and the other end connected to the water inlet of the second water pump 86. The water absorbent cotton is a porous water-absorbing material. Its basic principle is to produce a capillary phenomenon under the action of force through the pore structure to absorb the surrounding water. The surface area of ​​the water absorbent cotton is large, which can provide a large amount of water absorption area and can absorb a large amount of water in a short time.

[0056] The bottom surface of the absorbent cotton block 85 is flush with the bottom surface of the frame 2. After reaching the position to be detected and placing the frame 2 completely on the road surface to be detected through two sets of driving components 7, the first water pump 82 is started to pump out the water stored in the water reservoir 81, and the water is sent to the drainage channel 83 through the water supply pipe 84. Finally, the water is discharged obliquely downward through the drainage channel 83 and poured on the road surface, so that the water flow continues to flow on the road surface to flush the road surface to simulate the water erosion effect on the road surface, and then the road surface's ability to resist rainwater erosion is tested to obtain the strength of the road surface; when the first water pump 82 pumps water, the water flows on the road surface toward the absorbent cotton block 85 on the opposite side. After contacting the absorbent cotton block 85, the absorbent cotton block 85 quickly absorbs the water into itself. At this time, the second water pump 86 is started to pump the water in the absorbent cotton block 85 back into the water reservoir 81 through the water pumping pipe 87 to achieve a cyclic continuous flushing test of the road surface.

[0057] Optionally, the circulating flushing part 8 further includes a rubber frame strip 88 installed on the bottom surface of the frame body 2, and a water-absorbing cotton strip 89 installed inside the rubber frame strip 88;

[0058] The absorbent cotton strips 89 are in contact with the absorbent cotton blocks 85. When the frame 2 is placed on the road surface, with the action of the two sets of driving components 7, the rubber frame strips 88 on the bottom of the frame 2 can freely adapt to the conditions of the road surface to be tested, such as filling potholes or deforming according to the curvature of the road surface, thereby ensuring a tight connection between the frame 2 and the road surface, and the absorbent cotton strips 89 ensure that part of the water flowing sideways is absorbed and collected on the absorbent cotton blocks 85, thereby preventing a large gap between the frame 2 and the road surface from causing a large amount of water to flow out, effectively avoiding a large amount of waste of water resources while ensuring that water is recovered into the water reservoir 81 as much as possible, so as to ensure the continuity of road scouring detection, reduce the frequency of adding water to the water reservoir 81, and reduce the burden on the staff.

[0059] Optionally, the heavy pressure speed grinding part 9 includes a supporting platform 91 installed on the outer wall of the frame 2, an impact cylinder 92 arranged on the supporting platform 91, two groove plates 93 installed in the frame 2, and the open ends of the two groove plates 93 are opposite to each other, a sliding plate 94 slidably installed in the two groove plates 93, an electric jack 95 invertedly installed on the bottom surface of the sliding plate 94, a cross plate 96 connected to the output end of the electric jack 95, a frame 97 installed on the bottom surface of the cross plate 96, and a roller 98 rotatably installed on the frame 97. After driving the electric jack 95 to push the roller 98 down to the road surface, continuing to drive the electric jack 95 can further increase the pressure on the road surface from the roller 98, thereby simulating the effect of the vehicle load and detecting the compressive strength of the road surface to evaluate its bearing capacity.

[0060] Optionally, the heavy pressure speed grinding part 9 further includes a fixed clamping plate 99 integrally connected to the side of the transverse plate 96, a movable clamping plate 991 movably connected to the side of the transverse plate 96, a bolt 992 screwed on the fixed clamping plate 99 and the movable clamping plate 991, a connecting piece 993 whose tail passes through the fixed clamping plate 99 and the movable clamping plate 991, and a grinding plate 994 installed on the connecting piece 993;

[0061] The roller 98 is arranged side by side with the grinding disc 994, and the roller 98 is flush with the grinding disc 994. The impact cylinder 92 is an existing cylinder with special functions, with strong impact force and fast speed. When the roller 98 is in contact with the grinding disc 994 and the road surface, the impact cylinder 92 is driven to quickly pull the sliding plate 94 back and forth in the two groove plates 93, so that the grinding disc 994 and the road surface have translational friction, and the roller 98 and the road surface have rolling friction, so as to simulate the actual use condition and detect the ability of the road surface to resist wear. At the same time, the friction between the roller 98 and the road surface is the friction between the vehicle tire and the road surface. Under normal circumstances, the friction effect of the grinding disc 994 is stronger, thereby ensuring that the road surface is effectively tested for strength under different use requirements and higher standards, so as to more comprehensively grasp the strength of the road surface; after loosening the bolt 992, the connecting piece 993 can be moved up and down to adjust the height of the grinding disc 994, and then when the grinding disc 994 and the roller 98 are unevenly worn, it is ensured that the two can always be at the same height to effectively test the road surface; when testing the road surface for resistance to wear, the roller 98 and the grinding disc 994 cannot be pressed on the road surface with the force used to test the compressive strength of the road surface, so as to prevent unnecessary damage to the road surface;

[0062] The clamping surfaces of the fixed clamping plate 99 and the movable clamping plate 991 as well as the tail of the connecting member 993 are engraved with grid-like convex patterns, which effectively enhance the friction force and ensure that the connecting member 993 is firmly and stably clamped to prevent unnecessary movement of the connecting member 993 when the road surface is tested, thereby affecting the test.

[0063] Optionally, the water storage container 81 is composed of a plurality of cylindrical containers, and the plurality of cylindrical containers are interconnected except for the first and last two;

[0065] A number of the electric heaters 892 are inserted downward into the water reservoir 81 so that there is an electric heater 892 in each cylindrical container. After starting the electric heaters 892, the water in the water reservoir 81 can be heated, thereby increasing the water temperature so that the water flushed onto the road surface has a certain temperature, thereby simulating different environmental conditions, verifying the condition of the road surface at different temperatures, and ensuring its stability and durability under different climatic conditions.

[0066] Optionally, the circulation flushing unit 8 further includes a booster pump 893 disposed on the semi-enclosed platform 4;

[0067] The water supply pipe 84 is cut off in the middle and connected to the booster pump 893. The water flow is pressurized again in the process of flowing to the drainage channel 83, making the water flow stronger, so as to flush the road surface with a strong water flow, ensuring that a variety of situations can be simulated, improving the detection effect of the road surface, and ensuring the effectiveness of the detection effect;

[0068] A section of the water supply pipe 84 close to the booster pump 893 and a section of the water suction pipe 87 close to the second water suction pump 86 are both corrugated tubes, and the other parts are made of hard materials, ensuring that parts of the water supply pipe 84 and the water suction pipe 87 can move flexibly, thereby ensuring that in the process of lowering the frame 2, the corresponding parts of the water supply pipe 84 and the water suction pipe 87 can be pulled accordingly, so that the frame 2 can be moved downward smoothly without affecting water delivery and pumping.

[0069] Optionally, the height of the absorbent cotton block 85 increases gradually from one end inserted into the suction pipe 87 to the other end, so that after the absorbent cotton block 85 absorbs water, the moisture inside it can automatically gather to the lower end of the suction pipe 87, so that the suction pipe 87 can quickly draw out the moisture in the absorbent cotton block 85, so that the water absorption of the absorbent cotton block 85 and the water pumping of the suction pipe 87 are quickly connected to quickly pump out the water that flushes the road surface, so as to prevent a large amount of water from accumulating in the frame 2 and affecting the flushing detection effect of the road surface.

[0070] Optionally, the driving assembly 7 includes a rack 71 installed on the outer wall of the frame 2, a second frame 72 and a motor 73 arranged on the first base 3, a first gear 74 rotatably installed on the second frame 72, and the first gear 74 is meshed with the rack 71, a second gear 75 is installed on the output end of the motor 73, and the second gear 75 is meshed with the first gear 74, the motor 73 driving the two sets of driving assemblies 7 directly drives the second gear 75 to rotate, and uses the second gear 75 to drive the first gear 74 to rotate, and finally meshes with the rack 71 to ensure that the frame 2 is firmly lowered under a series of transmissions, and the frame 2 is automatically placed on the road surface to be detected, and the frame 2 is used to frame the area to be detected on the road surface, so as to form a detection interval relatively isolated inside and outside for subsequent various detections.

[0071] Optionally, it should be specifically stated that, during actual testing, the road surface can be flushed with water at room temperature first, and then the water can be heated and flushed with hot water, or hot and cold water can be used alternately. The road surface can also be pressurized or rubbed simultaneously while flushing, to ensure that the testing methods can be flexibly combined to simulate complex environmental factors and more effectively complete the strength test of the road surface.

At the same time, start the second pump 86. After the water flows through the road surface, it is quickly sucked away by the absorbent cotton block 85 opposite the drainage channel 83. Then the second pump 86 pumps the water in the absorbent cotton block 85 back into the water reservoir 81 through the pumping pipe 87. At the same time, start a plurality of electric heaters 892 to continuously heat the water in the water reservoir 81.
