DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] Example 1: Reference Figure 1-Figure 8 A method for paving hillside stones in high-water content silty clay areas comprises the following steps:

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

[0035] The mountain stones are transported by transport vehicles based on the amount of mountain stones used;

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

[0037] Using a bulldozer to tidy up the pre-paved route to obtain a tidy paved route;

[0038] Use a vibratory roller to compact the paving route to complete the paving.

[0039] The principle of the above scheme is:

[0040] Firstly, the usage of mountain stone is calculated based on the length of the pre-construction route in the high-water content silty clay area, and then the mountain stone is actively transported by transport vehicles. During the transportation process, the mountain stone, i.e., the stone, is placed on the pre-construction route. At this time, since the stone has not been sorted by the engineering vehicle, a pre-paving route is obtained first, and then a bulldozer is used to sort the pre-paving route, that is, to flatten it and obtain a sorted paving route. Finally, a vibratory roller is used to roll and level the stone on the sorted paving route to complete the paving construction process.

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

[0042] During the construction process, bulldozers are used to organize the pre-paved routes, which reduces the use of engineering vehicles, greatly improves construction efficiency, and reduces the difficulty of scheduling between multiple different vehicles during on-site construction.

[0043] Example 2: Reference Figure 1-Figure 8 When obtaining the amount of mountain stone used based on the pre-construction route, according to the width of 18m and the loose thickness of the mountain stone cushion layer of 0.3m, the amount of mountain stone per linear meter is 5.4m 3 .

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

[0045] In the process of road paving, mountain stone is used as solid filler. Mountain stone is a commonly used building material with low difficulty in obtaining. Since mountain stone is composed of limestone, granite, sandstone, shale, gravel, fine sand and fine soil, its average density has two different parameters, specifically: the density in loose state is 1.5-1.8 tons / cubic meter, and the density in compacted state is 2.0-2.5 tons / cubic meter. It can be seen that in the loose state, that is, when mountain stone is used as the stone material for the pre-paving route on the pre-construction route, it can be obtained through stone The fine particles in the material, i.e. fine sand and fine soil, or a small part of the rock material, i.e. limestone, granite, sandstone, shale and gravel, absorb the moisture in the silty clay. The absorption of moisture by the fine particles can increase the overall density and adhesion of the stone material, and can wrap the rock material that has absorbed water to prevent it from continuing to absorb 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 compactness and thus obtain excellent bearing capacity;

[0046] Since the moisture content of the high-moisture silty clay area is too high, and the road paved in this area needs to be accessible to transport vehicles with an upper limit of 100 tons of carrying capacity, in order to evenly distribute the weight of the vehicles on the silty clay and effectively prevent the road from collapsing, it is necessary to use mountain stone with a compaction density of 2.5 tons / cubic meter for paving with a width of 18m and a loose thickness of 0.3m. The stone volume per linear meter of mountain stone is 5.4m 3 , the carrying capacity of the transport vehicle can be calculated to complete the calculation of the number of vehicle departures required for road paving, which reduces the difficulty of vehicle scheduling at the construction site and can also meet the bearing capacity requirements of the road surface after paving.

[0047] Example 3: Reference Figure 1-Figure 8 The stone volume per meter of mountain stone is 5.4m 3 After that, the amount of stone used per meter of mountain stone is 5.4m 3 Multiply it by the length of the planned construction route to get the amount of mountain stone used.

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

[0049] Based on the stone volume of 5.4m per linear meter of mountain stone 3 The amount of mountain stone used can be obtained by multiplying it by the length of the pre-construction route, and the overall amount of mountain stone used in the entire construction process can be accurately obtained, which is convenient for quick and accurate preparation of stones before construction, greatly improving the construction efficiency.

[0050] Example 4: Reference Figure 1-Figure 8 The width of the pre-paved route is 6m and the thickness is 0.9m.

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

[0052] In order to obtain a road surface with a width of 18m and a loose thickness of 0.3m for the mountain stone cushion layer, a transport vehicle is used to first obtain a pre-paved route with a width of 6m and a thickness of 0.9m. Therefore, when a bulldozer is used to arrange the stones of the pre-paved route, sufficient construction margin can be retained to arrange the road surface multiple times to prevent the paving thickness or width from failing to meet the design standards due to the number of construction times.

[0053] Example 5: Reference Figure 1-Figure 8 When the bulldozer is used to arrange the pre-paved route to obtain the arranged paved route, the mountain stones are transported to both sides of the center line of the pre-paved route along the center line of the pre-paved route.

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

[0055] Align the bulldozer with the center line of the pre-paved route, and use the bulldozer to spread the mountain stone to both sides of the pre-paved route, further improving the consistency of the mountain stone paving thickness after paving.

[0056] Example 6: Reference Figure 1-Figure 8 In the process of spreading the mountain stones to both sides of the pre-paved route, the paved route is arranged when the loose paving thickness of the mountain stones reaches 0.3m.

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

[0058] When the loose paving thickness of the mountain stone reaches the designed value of 0.3m, the paving route is arranged.

[0059] Example 7: Reference Figure 1-Figure 8 When using a vibratory roller to compact the paved route, a vibratory roller weighing 22 tons is selected to work.

[0060] The vibratory roller weighing 22 tons is used for static pressure 1 time and weak vibration 3 times.

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

[0062] After the paving route is arranged, a 22-ton vibratory roller is used to vibrate it. The vibration method is static pressure 1 time and weak vibration 3 times, which can achieve the compaction of the mountain stone.

[0063] Example 8: Reference Figure 1-Figure 8 After one static pressure and three weak vibrations, the paving route is paved until the solid volume ratio reaches 73%.

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

[0065] After the vibratory roller has finished compacting the road surface, the solid volume ratio can be measured by weighing, volumetric method or density test to reach 73%, confirming that the compaction of the road surface is complete.

[0066] Example 9: Reference Figure 1-Figure 8 The bulldozer comprises: 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 comprises: a mounting frame 2, an auger shaft 3, an auger piece 4, a motor 5, a sprocket 6, a chain 7, a sprocket 8 and a bulldozer 9, the output end of the lifting mechanism is connected to the rear side of the bulldozer 9, the top of the bulldozer 9 is connected to the bottom of the mounting frame 2, the mounting frame 2 is rotatably connected to the auger shaft 3, the auger piece 4 and the sprocket 8 are connected to the auger shaft 3, the bulldozer 9 is arranged on the rear side of the auger piece 4, the sprocket 8 is connected to the sprocket 6 through the chain 7, the sprocket 6 is installed on the output shaft of the motor 5, the motor 5 is connected to the mounting frame 1, and the bottom of the mounting frame 2 is connected to the top of the bulldozer 11 through the buffer mechanism.

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

[0068] The rear side of the bulldozer 9 is away from the forward direction of the bulldozer. When the pre-paved route is arranged, the bottom of the mounting frame 2 is connected to the top of the bulldozer 9, and the bulldozer 9 is connected to the output end of the lifting mechanism of the bulldozer. When the bulldozer moves forward, the bulldozer 9 can be used to level the mountain stones and move the auger piece 4 to the pre-paved route. Then, the motor 5 is started, and the output end of the lifting mechanism of the bulldozer is started to move downward to drive the mounting frame 2 to move downward. The output shaft of the motor 5 drives the sprocket 6 to rotate, and the sprocket 6 drives the sprocket 2 8 and the auger shaft 3 to rotate through the chain 7, and finally the auger piece 4 is rotated. The auger piece 4 rotates while moving from top to bottom, and the bulldozer 9 and the buffer mechanism move from top to bottom, and the mountain stones are moved from the middle of the pre-paved route to one side of the pre-paved route through the cooperation of the guiding mechanism. The setting of the auger shaft 3, the auger piece 4 and the buffer mechanism greatly reduces the difficulty of arranging 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 Figure 1-Figure 8 The bulldozer 11 in the buffer mechanism has the same structure as the bulldozer 9. The bulldozer 11 is arranged on the front side of the auger piece 4. The bottoms of the bulldozer 9 and the bulldozer 11 are both arranged below the auger piece 4. The opposite surfaces of the bulldozer 9 and the bulldozer 11 form a guide cavity. The bottom end of the bulldozer 9 is arranged toward the auger piece 4, and the bottom end of the bulldozer 11 is arranged toward the auger piece 4.

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

[0071] Since the bulldozer 9 and the second bulldozer 11 have the same structure, and the bottoms of the two are both arranged below the auger piece 4, and the bottoms of the bulldozer 9 and the second bulldozer 11 are both arranged toward the auger piece 4, the opposing surfaces of the two constitute a guide cavity, and the guide cavity cooperates with the rotating guide cavity auger piece 4 to transport the mountain stone horizontally from the middle of the pre-paved route to one side of the pre-paved route, thereby ensuring the straightness of the mountain stone during transportation and further improving the accuracy of the mountain stone during loose paving.

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

[0074] After the device finishes paving a section of mountain stones, the bulldozer moves forward, and the position of the lifting mechanism can be locked at this time, so that the front side of the bulldozer 11 can contact the mountain stones during the forward process, and perform preliminary sorting on them, further reducing the difficulty of the auger piece 4 in conveying the mountain stones;

[0075] Since the front side of the bulldozer 11 is in contact with the mountain stone, the bulldozer 11 is connected to the mounting frame 2 through the connecting shaft 12, and the bottom of the bulldozer 11 moves toward the auger piece 4. Since the mounting plate 13 on the connecting shaft 12 is connected to the mounting frame 2 through the torsion spring 14, the torsion spring 14 twists and stores energy. When the bulldozer moves into place, under the elastic potential energy of the torsion spring 14, the connecting shaft 12, the mounting plate 13 and the bulldozer 11 rotate in the opposite direction and reset to prepare for the lateral transportation of the mountain stone.

[0076] Example 12: Reference Figure 1-Figure 8 The top of the positioning plate 15 is connected to the bottom of the mounting frame 2, and the positioning plate 15 is arranged perpendicularly to the auger shaft 3. The bottom of the mounting frame 2 is connected to a rotating motor 17, and 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, and the top of the guide plate 16 is arranged toward the output end of the auger piece 4 and is arranged perpendicularly to the positioning plate 15.

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

[0078] When the paving stones are transported horizontally, the positioning plate 15 can be aligned with the center line of the pre-paved route, and at the same time, the paving stones on the other side of the center line, that is, away from the auger piece 4, can be prevented from being transported, further improving the consistency of the paving thickness of the paving stones after the paving stones are transported horizontally;

[0079] A rotating motor 17 is connected to the bottom of the mounting frame 2. When the mountain stones are started to be transported horizontally, the guide plate 16 connected to the output shaft of the rotating motor 17 is vertically arranged with the positioning plate 15, which can ensure that the mountain stones are transported horizontally to the edge of the pre-paved route. In the process of transportation, the rotating motor 17 is started, and the guide plate 16 driven by the output shaft of the rotating motor 17 rotates. The bottom of the guide plate 16 moves from top to bottom, so that the mountain stones being transported contact with the side walls of the guide plate 16, and the mountain stones are transported horizontally from far to near, preventing the mountain stones from being locally accumulated during horizontal transportation, resulting in uneven loose paving thickness, and further avoiding local stress changes in the compacted road surface when subjected to force, which not only improves the bearing capacity after paving, but also avoids the collapse of the paved road surface after being subjected to force, thereby extending the service life of the road surface.

[0080] Example 13: Reference Figure 1-Figure 8A sprocket three 18 is connected to the output shaft of the motor 5, and the sprocket three 18 is transmission-connected to the sprocket four 20 through the chain two 19. The sprocket four 20 is mounted on the rotating shaft 21, and the rotating shaft 21 is rotationally connected to the mounting frame 2 and the pump casing 22. The pump casing 22 is connected to the mounting frame 2, and a plurality of fan blades 23 are connected to the rotating shaft 21. The fan blades 23 are arranged in the pump casing 22. One side of the pump casing 22 is connected to the end of the air outlet pipe 2 40, and the end of the air outlet pipe 24 is connected to the air outlet pipe 24. The other end of the air outlet pipe 24 is arranged toward the auger piece 4, and the other side of the pump casing 22 is connected to the end of the air inlet pipe 25.

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

[0082] The output shaft of the motor 5 drives the sprocket wheel 3 18 to rotate while rotating. The sprocket wheel 3 18 is connected to the sprocket wheel 4 20 through the chain 2 19, and then drives the rotating shaft 21 to rotate. The fan blades 23 connected to the rotating shaft 21 input the external air into the pump housing 22 through the fan blades 23, and then enter the air outlet pipe 24 through the air outlet pipe 20, and output it to the top of the auger piece 4 through the air outlet pipe 24. The flowing air cooperates with the guide cavity to discharge the dust generated by the auger piece 4 during operation through the guide plate 16. A dust removal device can be used at the construction site to process the generated dust. The dust removal device can use the water mist spray system in the prior art to absorb and process the dust, which greatly improves the ability to protect the health of the workers on the construction site and reduces the damage to the surrounding ecological environment during construction. The dust treatment through the air outlet pipe 24 can also improve the visibility of the bulldozer and its surrounding workers to the construction site, so that it is convenient to obtain the parameters of the equipment at work in a timely manner to prevent the thickness of the mountain skin stone pine paving from having obvious errors.

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

[0084] Example 14: Reference Figure 1-Figure 8The auger shaft 3 has a storage chamber 26 inside, and hydraulic oil is stored in the storage chamber 26. The inner wall of the storage chamber 26 is rotatably connected to the end of a rubber tube 27, and the rubber tube 27 is connected to the mounting frame 2. The other end of the rubber tube 27 is connected to a liquid pump shell 28, and the liquid pump shell 28 is longitudinally slidably connected to the mounting frame 2. The inner wall of a hollow rubber wheel 30 is connected to the auger shaft 3, and the expansion chamber 31 of the hollow rubber wheel 30 is connected to the end of a liquid guide tube 32. The other end of the liquid guide tube 32 is placed in the storage chamber 26, and the top of the liquid pump shell 28 is connected to the mounting frame 2 through a spring 33. The liquid pump shell 2 8 is rotatably connected to a pump shaft 34, a pump blade 35 is connected to the pump shaft 34, the pump shaft 34 is placed on the side wall outside the liquid pump housing 28 and is connected to a guide wheel 36, the guide wheel 36 is frictionally matched 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 rubber tube 37, the other end of the rubber tube 37 is connected to the end of a cooling tube 38, the cooling tube 38 is connected to the mounting frame 2, the bending portion 39 of the cooling tube 38 is arranged toward the output end of the air outlet tube 40, the cooling tube 38 is rotatably connected to the other end of the auger shaft 3, and the other end of the cooling tube 38 is placed in the storage chamber 26.

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

[0086] The air outlet pipe 24 cools down the outside of the auger piece 4 when the device is working. In order to prevent the temperature difference between the inside and outside of the auger piece 4 from causing deformation and reducing its service life, a storage chamber 26 is opened inside the auger shaft 3. Hydraulic oil is stored in the storage chamber 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, the pump shaft 34 can be driven to rotate. The pump shaft 34 drives the rotation of the pump blade 35. A pressure difference occurs in the liquid pump housing 28. After the hydraulic oil enters the liquid pump housing 28 through the rubber tube 27, it is input into the cooling pipe 38 through the rubber tube 2 37. When the hydraulic oil passes through the bending part 39, the air output by the air outlet pipe 2 40 can cool down the hydraulic oil therein. 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 piece 4, and this cycle is repeated.

[0087] When the external environment temperature is too high, or the temperature of the auger blade 4 is too high in the working state, the volume of the hydraulic oil in the storage chamber 26 expands, and part of the hydraulic oil enters the expansion chamber 31 of the hollow rubber wheel 30 through the liquid guide tube 32;

[0088] When the ambient temperature is low, or the temperature of the auger blade 4 is low during operation, the volume of the hydraulic oil in the storage chamber 26 shrinks to a certain extent, and the hydraulic oil in the expansion chamber 31 enters the storage chamber 26 through the liquid guide tube 32;

[0089] When the hydraulic oil in the expansion chamber 31 increases, the volume of the hollow rubber wheel 30 increases, thereby increasing the area of ​​its side wall, so that the rotation speed of the guide wheel 36 that frictionally cooperates with it is accelerated, which can quickly cool the device to prevent overheating;

[0090] When the volume of the hydraulic oil in the expansion chamber 31 decreases, the volume of the hollow rubber wheel 30 decreases, thereby reducing the area of ​​its side wall, thereby reducing the rotation speed of the guide wheel 36 that is frictionally matched with it, preventing a large pressure difference between the input end and the output end of the liquid pump housing 28, further avoiding a pressure difference at both ends of the storage chamber 26, preventing bubbles from appearing in the hydraulic oil therein, and preventing the device from reducing its ability to absorb heat from the hydraulic oil when it is working. The change in the volume of the hollow rubber wheel 30 also realizes the device's ability to adjust and control itself.

[0091] In order to prevent the hollow rubber wheel 30 from getting stuck on the guide wheel 36 after the volume of the hollow rubber wheel 30 increases, and to prevent the hollow rubber wheel 30 from being unable to frictionally cooperate with the guide wheel 36 after the volume of the hollow rubber wheel 30 decreases, a mounting frame 2 is provided to be connected to the top of the liquid pump housing 28 through a spring 33. Under the cooperation of the longitudinal sliding connection between the liquid pump housing 28 and the mounting frame 2, when the volume of the hollow rubber wheel 30 increases, the liquid pump housing 28 moves upward and compresses the spring 33. When the volume of the hollow rubber wheel 30 decreases, the liquid pump housing 28 moves downward under the action of the elastic force of the spring 33.

[0092] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
