Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a method for paving mountain stone in silty clay areas with high moisture content. Background Technology

[0002] Road paving refers to the construction process of laying road surfaces on the roadbed, and it is an important part of road construction. The main purpose of road paving is to provide vehicles and pedestrians with a flat, stable, and durable driving and walking surface, while also meeting requirements for drainage, anti-skid, noise reduction, and other aspects. Road paving projects are particularly difficult in areas with high moisture content silty clay.

[0003] In existing technologies, after the stones are placed on the roadbed, loaders and excavators are usually used to sort the stones, which involves a large number of engineering vehicles and is extremely inefficient. Summary of the Invention

[0004] This invention provides a method for paving mountain surface stones in silty clay areas with high moisture content, in order to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a method for paving mountain surface stones in high-moisture-content silty clay areas, comprising the following steps:

[0006] The amount of mountain stone used is obtained based on the pre-construction route;

[0007] Based on the amount of mountain stone used, transport vehicles are used to transport the mountain stone;

[0008] When transporting mountain stone, the mountain stone is laid on a pre-construction route to obtain a pre-paved route;

[0009] The pre-paved route is shaped using a bulldozer to obtain the shaped paved route;

[0010] The paving is completed by compacting the prepared paving route using a vibratory roller.

[0011] Preferably, when obtaining the amount of mountain stone used based on the pre-construction route, with a width of 18m and a loose thickness of 0.3m for the mountain stone bedding layer, the amount of mountain stone used per linear meter is 5.4m3.

[0012] Preferably, after obtaining the stone volume of 5.4 m3 per linear meter of mountain stone, the stone volume of 5.4 m3 per linear meter of mountain stone is multiplied by the length of the pre-construction route to obtain the stone volume usage of the mountain stone.

[0013] Preferably, the width of the pre-paved route is 6m.

[0014] Preferably, the thickness of the pre-paved route is 0.9m.

[0015] Preferably, when using a bulldozer to tidy up the pre-paved route to obtain the tidyed paved route, the mountain stone is transported along the centerline of the pre-paved route to both sides of the centerline of the pre-paved route.

[0016] Preferably, during the process of spreading the mountain stone to both sides of the pre-paved route, the paved route is completed after the loose thickness of the mountain stone reaches 0.3m.

[0017] Preferably, a 22-ton vibratory roller is used when compacting the paved road surface.

[0018] Preferably, when using a vibratory roller with a weight of 22 tons, the operation involves one static compaction pass and three weak vibration passes.

[0019] Preferably, the paving is completed after the solid volume fraction in the paving route reaches 73% following one pass of static pressure and three passes of weak vibration.

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. 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.

[0033] Example 1: Reference Figures 1-8 A method for paving stone in silty clay areas with high moisture content includes the following steps:

[0034] The amount of mountain stone used is obtained based on the pre-construction route;

[0035] Based on the amount of mountain stone used, transport vehicles are used to transport the mountain stone;

[0036] When transporting mountain stone, the mountain stone is laid on a pre-construction route to obtain a pre-paved route;

[0037] The pre-paved route is shaped using a bulldozer to obtain the shaped paved route;

[0038] The paving is completed by compacting the prepared paving route using a vibratory roller.

[0039] The principle behind the above scheme is as follows:

[0040] First, the amount of mountain stone used is calculated based on the length of the pre-construction route in the high-moisture-content silty clay area. Then, the mountain stone is actively transported by transport vehicles. During the transportation process, the mountain stone, i.e. the stone material, is placed on the pre-construction route. Since the stone material has not been sorted by the construction vehicles, the pre-paving route is obtained first. Then, a bulldozer is used to sort the pre-paving route, i.e., to lay it flat, thus obtaining the sorted paving route. Finally, a vibratory roller is used to compact and level the stone material on the sorted paving route to complete the paving construction process.

[0041] The beneficial effects of the above scheme are as follows:

[0042] During construction, bulldozers were used to organize the pre-paved route, reducing the use of engineering vehicles, greatly improving construction efficiency, and reducing the difficulty of scheduling various vehicles on site.

[0043] Example 2: Reference Figures 1-8 When determining the amount of rock used based on the pre-construction route, with a width of 18m and a loosely laid rock bedding layer thickness of 0.3m, the amount of rock used per linear meter of rock is 5.4m. 3 .

[0044] The principles and beneficial effects of the above scheme are as follows:

[0045] In road paving, mountain stone is used as a solid filler. Mountain stone is a commonly used building material that is easy to obtain. Because mountain stone is composed of limestone, granite, sandstone, shale, gravel, fine sand, and fine soil, its average density has two different parameters: a density of 1.5-1.8 tons / cubic meter in a loose state and a density of 2.0-2.5 tons / cubic meter in a compacted state. Therefore, when mountain stone is used in a loose state as the stone material for pre-paved roads, it can be easily... The fine particles in the material, namely fine sand and fine soil, or a small amount of rock material, namely limestone, granite, sandstone, shale and gravel, absorb the water in the silty clay. The absorption of water by the fine particles can increase the overall density and cohesion of the stone material, and can also wrap the rock material that has already absorbed water to prevent it from absorbing water in the soil. At this time, the rock material already has a certain moisture content, and after being compacted by engineering vehicles without absorbing too much water, it can have excellent compaction and thus obtain excellent load-bearing capacity.

[0046] Due to the excessively high moisture content of the silty clay in the area, and the requirement for the road surface to accommodate vehicles with a maximum carrying capacity of 100 tons, it is necessary to distribute the weight of the vehicles evenly on the silty clay and effectively prevent road collapse. Therefore, a 18m wide, 0.3m thick layer of compacted granite with a density of 2.5 tons / cubic meter is required for paving. This results in a stone volume of 5.4m³ per linear meter of granite. 3 The number of vehicle departures required for road paving can be calculated by measuring the carrying capacity of transport vehicles, reducing the difficulty of vehicle scheduling at the construction site and meeting the load-bearing capacity requirements of the paved road surface.

[0047] Example 3: Reference Figures 1-8 The volume of stone obtained per meter of mountain stone is 5.4 m³. 3 Subsequently, the volume of stone excavation per meter of mountain stone was 5.4m. 3 The amount of mountain stone used is obtained by multiplying it by the length of the pre-construction route.

[0048] The principles and beneficial effects of the above scheme are as follows:

[0049] The volume of stone excavation per meter of mountain stone is 5.4m. 3 Multiplying the amount of mountain stone used by the length of the pre-construction route yields the total amount of mountain stone used throughout the entire construction process. This allows for quick and accurate preparation of the stone materials before construction, greatly improving the efficiency of the project.

[0050] Example 4: Reference Figures 1-8 The pre-paved route is 6m wide and 0.9m thick.

[0051] The principles and beneficial effects of the above scheme are as follows:

[0052] To obtain a road surface with a width of 18m and a loose paving thickness of 0.3m for the mountain stone subbase, a pre-paved road surface with a width of 6m and a thickness of 0.9m is first obtained using transport vehicles. Therefore, when using bulldozers to arrange the stones of the pre-paved road, sufficient construction allowance can be left to arrange the road surface multiple times to prevent the thickness or width of the paved road from failing to meet the design standards due to the number of construction operations.

[0053] Example 5: Reference Figures 1-8 When using a bulldozer to straighten the pre-paved route to obtain the straightened paved route, the mountain stone is transported along the centerline of the pre-paved route to both sides of the centerline of the pre-paved route.

[0054] The principles and beneficial effects of the above scheme are as follows:

[0055] Align the bulldozer with the centerline of the pre-paved route, and use the bulldozer to spread the stone on both sides of the pre-paved route, which further improves the consistency of the loose thickness of the stone after paving.

[0056] Example 6: Reference Figures 1-8 During the process of spreading the mountain stone to both sides of the pre-paved route, the paved route is completed when the loose thickness of the mountain stone reaches 0.3m.

[0057] The principles and beneficial effects of the above scheme are as follows:

[0058] Once the loose paving thickness of the mountain stone reaches the design value of 0.3m, the paving route is finalized.

[0059] Example 7: Reference Figures 1-8 When using a vibratory roller to compact the paved road surface, a vibratory roller weighing 22 tons is selected for operation.

[0060] The selected vibratory roller, weighing 22 tons, is used for one pass of static compaction and three passes of weak vibration.

[0061] The principles and beneficial effects of the above scheme are as follows:

[0062] After obtaining the paving route, a 22-ton vibratory roller is used to vibrate it. The vibration method is one static compaction and three weak vibrations to compact the mountain stone.

[0063] Example 8: Reference Figures 1-8 After one pass of static pressure and three passes of weak vibration, the solid volume ratio in the paving route is reduced to 73% before paving is completed.

[0064] The principles and beneficial effects of the above scheme are as follows:

[0065] After the vibratory roller has finished compacting the road surface, the solid volume fraction can be measured to be 73% by methods such as weighing, volumetric method or density test, to confirm that the road surface compaction is complete.

[0066] Example 9: Reference Figures 1-8 The bulldozer includes: a bulldozer body, a lifting mechanism, and a sorting mechanism 1. The end of the bulldozer body is connected to the end of the lifting mechanism, and the output end of the lifting mechanism is connected to the sorting mechanism 1 to sort the pre-paved route to obtain a sorted paved route. The sorting mechanism 1 includes: a mounting frame 2, an auger shaft 3, an auger plate 4, a motor 5, a sprocket 6, a chain 7, a second sprocket 8, and a bulldozer blade 9. The output end of the lifting mechanism is connected to the rear side of the bulldozer blade 9. The top of the bulldozer blade 9 is connected to the bottom of the mounting frame 2. The auger shaft 3 is rotatably connected to the mounting frame 2. The auger plate 4 and the second sprocket 8 are connected to the auger shaft 3. The bulldozer blade 9 is located on the rear side of the auger plate 4. The second sprocket 8 is connected to the chain 7 and the sprocket 6 through a transmission connection. The sprocket 6 is mounted on the output shaft of the motor 5. The motor 5 is connected to the mounting frame 1. The bottom of the mounting frame 2 is connected to the top of the second bulldozer blade 11 through a buffer mechanism.

[0067] The principles and beneficial effects of the above scheme are as follows:

[0068] The rear of the bulldozer blade 9 is away from the direction of the bulldozer's advance. When tidying up the pre-paved route, the bottom of the mounting frame 2 is connected to the top of the bulldozer blade 9. The bulldozer blade 9 is connected to the output end of the bulldozer's lifting mechanism. When the bulldozer moves forward, the bulldozer blade 9 can be used to level the rock and move the auger plate 4 onto the pre-paved route. Then, the motor 5 is started, and at the same time, the output end of the bulldozer's lifting mechanism is started to move downward, driving the mounting frame 2 downward. The output shaft of the motor 5 drives the sprocket 6 to rotate. The sprocket 6 drives the sprocket 8 and the auger shaft 3 to rotate through the chain 7, which finally makes the auger plate 4 rotate. The auger plate 4 rotates from top to bottom. The bulldozer blade 9 and the buffer mechanism move from top to bottom. With the cooperation of the guiding mechanism, the rock is moved from the middle of the pre-paved route to one side of the pre-paved route. The setting of the auger shaft 3, auger plate 4 and buffer mechanism greatly reduces the difficulty of tidying up the pre-paved route, that is, reduces the difficulty of loose paving thickness, reduces the use of engineering vehicles, and greatly reduces the difficulty of vehicle scheduling at the construction site.

[0069] Example 10: Reference Figures 1-8 The second bulldozer blade 11 in the buffer mechanism has the same structure as the 9 bulldozer blade. The second bulldozer blade 11 is located on the front side of the auger plate 4. The bottoms of both the 9 bulldozer blade and the second bulldozer blade 11 are located below the auger plate 4. The opposite surfaces of the 9 bulldozer blade and the second bulldozer blade 11 form a guide cavity. The bottom end of the 9 bulldozer blade faces the auger plate 4, and the bottom end of the second bulldozer blade 11 faces the auger plate 4.

[0070] The principles and beneficial effects of the above scheme are as follows:

[0071] Since bulldozer blade 9 and bulldozer blade 2 11 have the same structure and their bottoms are both located below the auger plate 4, and the bottoms of bulldozer blade 9 and bulldozer blade 2 11 are both facing the auger plate 4, their opposite surfaces form a guide cavity. The guide cavity cooperates with the rotating guide cavity auger plate 4 to transport the mountain stone from the middle of the pre-paved route to one side of the pre-paved route, ensuring the straightness of the mountain stone during transportation and further improving the accuracy of the mountain stone during loose laying.

[0072] Example 11: Reference Figures 1-8 The buffer mechanism includes a connecting shaft 12, a mounting plate 13, and a torsion spring 14. The top of the bulldozer blade 11 is connected to the connecting shaft 12, the connecting shaft 12 is rotatably connected to the mounting frame 2, and the end of the connecting shaft 12 is connected to the mounting plate 13. The mounting plate 13 is connected to the mounting frame 2 through the torsion spring 14.

[0073] The principles and beneficial effects of the above scheme are as follows:

[0074] After the device finishes laying a section of mountain stone, the bulldozer moves forward. At this time, the position of the lifting mechanism can be locked. Therefore, the front side of the bulldozer blade 211 can come into contact with the mountain stone during the forward movement to perform preliminary sorting, further reducing the difficulty of the auger blade 4 in conveying the mountain stone.

[0075] Since the front side of the bulldozer blade 11 is in contact with the rock, the bulldozer blade 11 is rotatably connected to the mounting frame 2 via the connecting shaft 12. The bottom of the bulldozer blade 11 moves toward the auger plate 4. Since the mounting plate 13 on the connecting shaft 12 is connected to the mounting frame 2 via the torsion spring 14, the torsion spring 14 stores energy by torsion. When the bulldozer moves into position, under the elastic potential energy of the torsion spring 14 returning to its original position, the connecting shaft 12, the mounting plate 13 and the bulldozer blade 11 rotate in opposite directions to return to their original positions, preparing for the lateral transport of the rock.

[0076] Example 12: Reference Figures 1-8 The bottom of the mounting frame 2 is connected to the top of the positioning plate 15. The positioning plate 15 is perpendicular to the auger shaft 3. The bottom of the mounting frame 2 is connected to the rotating motor 17. The output shaft of the rotating motor 17 is rotatably connected to the bottom of the mounting frame 2. The output shaft of the rotating motor 17 is connected to the top of the guide plate 16. The top of the guide plate 16 is set towards the output end of the auger plate 4 and is perpendicular to the positioning plate 15.

[0077] The principles and beneficial effects of the above scheme are as follows:

[0078] When the mountain stone is being transported laterally, the positioning plate 15 can be aligned with the centerline of the pre-paved route, and at the same time, it can prevent the mountain stone on the other side of the centerline, that is, away from the auger plate 4, from being transported, which further improves the consistency of the loose thickness of the mountain stone after lateral transport.

[0079] The bottom of the mounting frame 2 is connected to a rotating motor 17. When the lateral conveying of the mountain stone begins, the guide plate 16 connected to the output shaft of the rotating motor 17 is perpendicular to the positioning plate 15, which ensures that the mountain stone is laterally conveyed to the edge of the pre-paved route. During the conveying process, the rotating motor 17 starts, and the output shaft of the rotating motor 17 drives the guide plate 16 to rotate. The bottom of the guide plate 16 moves from top to bottom, so that the mountain stone being conveyed comes into contact with the side wall of the guide plate 16. This allows the mountain stone to be laterally conveyed from far to near, preventing local accumulation of the mountain stone during lateral conveying, which would lead to uneven paving thickness. Furthermore, it can avoid local stress changes in the compacted road surface when under stress, which not only improves the bearing capacity after paving, but also prevents the paved road surface from collapsing after being under stress, thus extending the service life of the road surface.

[0080] Example 13: Reference Figures 1-8The output shaft of the motor 5 is connected to a sprocket 3 18, which is connected to a sprocket 4 20 via a chain 2 19. The sprocket 4 20 is mounted on a rotating shaft 21, which is rotatably connected to the mounting bracket 2 and the pump housing 22. The pump housing 22 is connected to the mounting bracket 2. Multiple fan blades 23 are connected to the rotating shaft 21, and the fan blades 23 are disposed inside the pump housing 22. One side of the pump housing 22 is connected to the end of an air outlet pipe 2 40, and the end of an air outlet pipe 24 is connected to the air outlet pipe 2 40. The other end of the air outlet pipe 24 is set towards the auger plate 4. The other side of the pump housing 22 is connected to the end of an air inlet pipe 25.

[0081] The principles and beneficial effects of the above scheme are as follows:

[0082] While the output shaft of motor 5 rotates, it drives sprocket 3 18 to rotate. Sprocket 3 18 is connected to sprocket 4 20 via chain 2 19, which in turn drives shaft 21 to rotate. Fan blades 23 connected to shaft 21 draw outside air into pump casing 22, and then through air outlet pipe 2 40 into air outlet pipe 24. The air is then output to the top of auger blade 4 through air outlet pipe 24. The flowing air, in conjunction with the guide cavity, can discharge the dust generated by auger blade 4 during operation through guide plate 16. Dust removal devices can be used on construction site to treat the generated dust. The dust removal device can use the existing water mist spray system to absorb and treat the dust, which greatly improves the health protection of construction site workers and reduces the damage to the surrounding ecological environment during construction. The dust treatment through air outlet pipe 24 can also improve the visibility of the bulldozer and surrounding workers on the construction site, making it easier to obtain the parameters of the equipment during operation in a timely manner and prevent significant errors in the thickness of the loose stone paving.

[0083] Because the rotating auger blade 4 generates heat through friction with the mountain stone, the air output through the air outlet pipe 24 can prevent the auger blade 4 from overheating during operation, thus avoiding damage or deformation due to overheating.

[0084] Example 14: Reference Figures 1-8The auger shaft 3 has a storage cavity 26 inside, which stores hydraulic oil. A rubber tube 27 is rotatably connected to the inner wall of the storage cavity 26. The rubber tube 27 is connected to the mounting bracket 2, and the other end of the rubber tube 27 is connected to a pump housing 28. The pump housing 28 is longitudinally slidably connected to the mounting bracket 2. A hollow rubber wheel 30 is connected to the inner wall of the auger shaft 3. A liquid guide tube 32 is connected to the expansion cavity 31 of the hollow rubber wheel 30. The other end of the liquid guide tube 32 is placed inside the storage cavity 26. The top of the pump housing 28 is connected to the mounting bracket 2 via a spring 33. A pump shaft 34 is rotatably connected inside the pump housing 28. A pump blade 35 is connected to the pump shaft 34. A guide wheel 36 is connected to the side wall of the pump shaft 34 outside the liquid pump housing 28. The guide wheel 36 is in frictional engagement with the side wall of the hollow rubber wheel 30. The top of the liquid pump housing 28 is connected to the end of a second rubber tube 37. The other end of the second rubber tube 37 is connected to the end of a cooling pipe 38. The cooling pipe 38 is connected to the mounting bracket 2. The bent part 39 of the cooling pipe 38 is set towards the output end of the second air outlet pipe 40. The other end of the cooling pipe 38 is rotatably connected to the other end of the auger shaft 3. The other end of the cooling pipe 38 is placed inside the storage cavity 26.

[0085] The principles and beneficial effects of the above scheme are as follows:

[0086] When the device is working, the air outlet 24 cools the outside of the auger blades 4. To prevent deformation caused by temperature difference between the inside and outside of the auger blades 4 and reduce their service life, a storage cavity 26 is opened inside the auger shaft 3. Hydraulic oil is stored in the storage cavity 26. Due to the rotation of the auger shaft 3, the hollow rubber wheel 30 is driven to rotate. Therefore, when the hollow rubber wheel 30 rubs against the guide wheel 36, it can drive the pump shaft 34 to rotate. The pump shaft 34 drives the pump blades 35 to rotate, and a pressure difference appears in the pump housing 28. After the hydraulic oil enters the pump housing 28 through the rubber tube 27, it is input into the cooling pipe 38 through the second rubber tube 37. When the hydraulic oil passes through the bend 39, the air output from the air outlet 40 can cool the hydraulic oil inside. The cooled hydraulic oil enters the other end of the auger shaft 3 through the other end of the cooling pipe 38. The cooled hydraulic oil further absorbs the heat from the auger blades 4, and this cycle is repeated.

[0087] When the ambient temperature is too high, or when the temperature of the auger plate 4 is too high during operation, the volume of the hydraulic oil in the storage chamber 26 expands, and some of the hydraulic oil enters the expansion chamber 31 of the hollow rubber wheel 30 through the guide pipe 32.

[0088] When the ambient temperature is low, or when the temperature of the auger plate 4 is low during operation, the volume of the hydraulic oil in the storage chamber 26 will shrink to a certain extent, and the hydraulic oil in the expansion chamber 31 will enter the storage chamber 26 through the guide pipe 32.

[0089] When the hydraulic oil in the expansion chamber 31 increases, the volume of the hollow rubber wheel 30 increases, which in turn increases the area of ​​its sidewall. As a result, the rotation speed of the guide wheel 36 that is in friction with it increases, which can quickly cool down the device and prevent it from overheating.

[0090] When the volume of hydraulic oil in the expansion chamber 31 decreases, the volume of the hollow rubber wheel 30 decreases, which in turn reduces the area of ​​its sidewall, thereby reducing the rotation speed of the guide wheel 36 that it rubs against, preventing a large pressure difference between the input and output ends of the pump housing 28, further avoiding a pressure difference between the two ends of the storage chamber 26, preventing air bubbles from forming in the hydraulic oil, and preventing a decrease in the heat absorption capacity of the hydraulic oil during operation. The change in the volume of the hollow rubber wheel 30 also enables the device to have autonomous adjustment and control capabilities.

[0091] To prevent the hollow rubber wheel 30 from jamming the guide wheel 36 as its volume increases, and to prevent the hollow rubber wheel 30 from failing to frictionally engage with the guide wheel 36 as its volume decreases, a mounting bracket 2 is provided that is connected to the top of the pump housing 28 via a spring 33. With the longitudinal sliding connection between the pump housing 28 and the mounting bracket 2, when the volume of the hollow rubber wheel 30 increases, the pump housing 28 moves upward and compresses the spring 33; when the volume of the hollow rubber wheel 30 decreases, the pump housing 28 moves downward under the elastic force of the spring 33.
