Description

Technical Field

[0001] This invention relates to the field of high embankment roadbed construction equipment, and more specifically, to a high embankment roadbed construction equipment and construction method for highways. Background Technology

[0002] High embankment construction should be carried out using a layered filling and compaction method, with the thickness of each layer determined by the type of fill material used.

[0003] Common defects in high embankment subgrades include overall or partial subsidence, longitudinal cracking, and sliding or slope collapse. During the construction of high embankment subgrades, it is necessary to carry out slope lining, layered filling, and layered compaction. During the compaction process, a compressive force perpendicular to the slope surface needs to be applied along the slope to prevent the slope from protruding or sliding during the compaction process. Currently, the common method is to stack stone bricks on the slope, which is difficult to construct, time-consuming, and the compressive effect of the stone bricks is not stable. Summary of the Invention

[0004] The purpose of this invention is to provide a construction device and method for high embankment roadbeds in order to solve the above-mentioned problems.

[0005] This invention provides a construction device for high embankment roadbeds, comprising two symmetrically arranged inclined lifting mechanisms, a splicing compaction mechanism, several end-face limiting templates, a compaction mechanism, an attachment mechanism, and a clamping mechanism sequentially arranged on the inclined lifting mechanisms, and an auxiliary positioning mechanism arranged on the splicing compaction mechanism. The end-face limiting templates are used to limit the length of the roadbed and restrict the movement direction of the backfill soil. The inclined lifting mechanisms are used to drive the compaction mechanism, the attachment mechanism, and the clamping mechanism to move along the inclined direction of the inclined lifting mechanism. The compaction mechanism is used to compact the roadbed slope. The attachment mechanism is used to press a designated part of the splicing compaction mechanism onto a designated position on the roadbed slope. The clamping mechanism is used to limit and clamp the part of the splicing compaction mechanism that is not attached to the roadbed slope. The auxiliary positioning mechanism is used to limit and fix the splicing compaction mechanism and make the splicing compaction mechanism tightly attached to the roadbed slope surface.

[0006] The spliced ​​pressing mechanism includes several alternately distributed first pressing plates and second pressing plates, several first hinges symmetrically connected to the top surface of the first pressing plate, and several second hinges symmetrically connected to the top surface of the second pressing plate. The first hinges and second hinges are hinged together. When the opposing sidewalls of the first pressing plate and the second pressing plate contact each other and limit each other, the top and bottom surfaces of the first pressing plate and the top and bottom surfaces of the second pressing plate are all in a coplanar state. The bottom surfaces of the first pressing plate and the second pressing plate are in contact with the roadbed slope surface.

[0007] As a further optimization of the present invention, the inclined lifting mechanism includes an inclined lifting frame, an inclined sliding groove disposed on the inclined lifting frame, a first slider, a second slider, and a third slider that are slidably connected from top to bottom in the inclined sliding groove, a guide wheel disposed on the top of the inclined lifting frame, and a plurality of traction machines disposed on the foundation. The output ends of the plurality of traction machines are respectively connected to the first slider, the second slider, and the third slider through a first traction rope, a second traction rope, and a third traction rope. The first slider is provided with a through hole for the second traction rope and the third traction rope to pass through, and the second slider is provided with a through hole for the third traction rope to pass through. The first traction rope, the second traction rope, and the third traction rope all pass around the guide wheel.

[0008] As a further optimization of the present invention, the compaction mechanism includes a first hydraulic cylinder movably connected to the first slider, a pressure plate connected to the output end of the first hydraulic cylinder, a steering motor fixedly connected to the first slider, a first gear connected to the movable shaft connecting the first hydraulic cylinder and the first slider, and a second gear connected to the output end of the steering motor, wherein the first gear and the second gear mesh.

[0009] As a further optimization of the present invention, the attachment mechanism includes a second hydraulic cylinder connected to the second slider, a first connecting frame connected to the output end of the second hydraulic cylinder, and a first roller movably connected to the first connecting frame, wherein the first roller contacts the top surface of the first pressing plate or the second pressing plate.

[0010] As a further optimization of the present invention, the clamping mechanism includes a third hydraulic cylinder connected to the third slider, a second connecting frame connected to the output end of the third hydraulic cylinder, a second roller movably connected to the second connecting frame, a limiting groove provided on the second connecting frame, a fourth slider slidably connected in the limiting groove, a third roller movably connected to the fourth slider, and a spring connected between the fourth slider and the inner wall of the limiting groove. When the third roller contacts the first hinge or the second hinge, the spring is in a compressed state, and the second roller contacts the bottom surface of the first pressing plate or the second pressing plate.

[0011] As a further optimization of the present invention, when an outward-protruding turning angle appears on the roadbed slope, the sidewalls of the first and second pressing plates at the corresponding positions are provided with inclined cutting surfaces. When the inclined cutting surfaces on the first pressing plate and the second pressing plate contact and form a limiting effect, the angle between the first pressing plate and the second pressing plate is the same as the outward-protruding turning angle on the roadbed slope.

[0012] As a further optimization of the present invention, when a concave turning angle appears on the roadbed slope, a right-angled trapezoidal supplementary material is welded to the sidewall of the first and second pressing plates at the corresponding position. When the right-angled trapezoidal material on the first pressing plate contacts the right-angled trapezoidal supplementary material on the second pressing plate and forms a limiting effect, the angle between the first pressing plate and the second pressing plate is the same as the concave turning angle on the roadbed slope.

[0013] As a further optimization of the present invention, the auxiliary positioning mechanism includes several positioning rods, which are used to limit and fix the first or second pressing plate located at the bottom of the roadbed slope to the foundation.

[0014] A method for constructing a high embankment roadbed, using the aforementioned high embankment roadbed construction device, includes the following steps:

[0015] Erect end face limiting templates and inclined lifting mechanisms, fill soil in the area between the two end face limiting templates or the existing roadbed and the end face limiting templates, and perform slope treatment when setting the height. Drive the compaction mechanism along the roadbed slope through the inclined lifting mechanism and compact the slope area it passes through.

[0016] One end of the splicing compaction mechanism is fixed to the foundation by an auxiliary positioning mechanism. Then, the attachment mechanism is driven to move along the roadbed slope by an inclined lifting mechanism. During the movement, the subsequent first and second compaction plates are attached along the compacted slope surface.

[0017] When an outward-protruding turning angle appears on the roadbed slope, the sidewalls where the first and second pressing plates meet at the corresponding positions are cut, and an inclined cutting surface is formed at the cut. When the inclined cutting surface on the first pressing plate and the inclined cutting surface on the second pressing plate meet and form a limiting effect, the angle between the first pressing plate and the second pressing plate is the same as the outward-protruding turning angle on the roadbed slope. The cut right-angled trapezoidal material is ready for use.

[0018] When a concave turning angle appears on the roadbed slope, the cut right-angled trapezoidal material is welded to the side wall of the first and second pressing plates at the corresponding position. The right-angled trapezoidal material on the first pressing plate contacts the right-angled trapezoidal material on the second pressing plate and forms a limiting effect, so that the angle between the first pressing plate and the second pressing plate always remains the same as the concave turning angle on the roadbed slope.

[0019] The process continues until the entire spliced ​​compaction mechanism completely covers the slope area, and then the parallel surface area of ​​the roadbed is compacted.

[0020] The beneficial effects of this invention are as follows: This invention, through an inclined lifting mechanism, a compaction mechanism, an attachment mechanism, and a clamping mechanism, can automatically compact roadbed slopes. The spliced ​​compaction mechanism is automatically compacted onto the roadbed slope. Only the beginning and end ends and turning corners of the spliced ​​compaction mechanism need to be limited and fixed by an auxiliary positioning mechanism to compact and limit the entire roadbed slope. This ensures that the roadbed slope will not bulge, collapse, or landslide during the compaction of the top plane of the roadbed, which not only improves the roadbed construction speed but also improves the construction quality of the roadbed.

[0030] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0031] like Figure 1 , Figure 7 and Figure 8 As shown, a highway high embankment subgrade construction device includes two symmetrically arranged inclined lifting mechanisms 1, a splicing compaction mechanism 5, several end-face limiting templates 6, a compaction mechanism 2, an attachment mechanism 3, and a clamping mechanism 4 sequentially arranged on the inclined lifting mechanism 1, and an auxiliary positioning mechanism 7 arranged on the splicing compaction mechanism 5. The end-face limiting templates 6 are used to limit the subgrade length and restrict the movement direction of the backfill soil. The inclined lifting mechanism 1 is used to drive the compaction mechanism 2, the attachment mechanism 3, and the clamping mechanism 4 to move along the inclined direction of the inclined lifting mechanism 1. The compaction mechanism 2 is used to compact the subgrade slope. The attachment mechanism 3 is used to press a designated part of the splicing compaction mechanism 5 onto a designated position on the subgrade slope. The clamping mechanism 4 is used to limit and clamp the part of the splicing compaction mechanism 5 that is not attached to the subgrade slope. The auxiliary positioning mechanism 7 is used to limit and fix the splicing compaction mechanism 5 and make the splicing compaction mechanism 5 tightly attached to the subgrade slope surface.

[0032] The splicing cladding mechanism 5 includes several alternately distributed first cladding plates 501 and second cladding plates 502, several first hinges 503 symmetrically connected to the top surface of the first cladding plate 501, and several second hinges 504 symmetrically connected to the top surface of the second cladding plate 502. The first hinges 503 and second hinges 504 are hinged together. When the opposing sidewalls of the first cladding plate 501 and the second cladding plate 502 are in contact and mutually restrained, the top and bottom surfaces of the first cladding plate 501 and the top and bottom surfaces of the second cladding plate 502 are in a coplanar state, and the bottom surfaces of the first cladding plate 501 and the second cladding plate 502 are in contact with the roadbed slope surface.

[0033] It should be noted that during the roadbed construction, the end face limiting template 6 and the inclined lifting mechanism 1 are first erected. The area between the two end face limiting templates 6 or the existing roadbed and the end face limiting template 6 is filled with soil. When the height is set, the slope is treated. The inclined lifting mechanism 1 drives the compaction mechanism 2 to move along the roadbed slope and compact the slope area it passes through.

[0034] One end of the splicing pressing mechanism 5 is fixed to the foundation by the auxiliary positioning mechanism 7. Then, the attaching mechanism 3 is driven to move along the roadbed slope by the inclined lifting mechanism 1. During the movement, the subsequent first pressing plate 501 and second pressing plate 502 are attached along the compacted slope surface.

[0035] When an outward-protruding turning angle appears on the roadbed slope, the sidewalls of the first pressing plate 501 and the second pressing plate 502 at the corresponding positions are cut, and an inclined cutting surface is formed at the cut. When the inclined cutting surface on the first pressing plate 501 and the inclined cutting surface on the second pressing plate 502 come into contact and form a limiting effect, the angle between the first pressing plate 501 and the second pressing plate 502 is the same as the outward-protruding turning angle on the roadbed slope. The cut right-angled trapezoidal material is ready for use.

[0036] When a concave turning angle appears on the roadbed slope, the cut right-angled trapezoidal material is welded to the side wall of the first pressing plate 501 and the second pressing plate 502 at the corresponding position. When the right-angled trapezoidal material on the first pressing plate 501 contacts the right-angled trapezoidal material on the second pressing plate 502 and forms a limiting effect, the angle between the first pressing plate 501 and the second pressing plate 502 is always kept in the same state as the concave turning angle on the roadbed slope.

[0037] The process continues until the entire splicing compaction mechanism 5 completely covers the slope area, and then the parallel surface area of ​​the roadbed is compacted.

[0038] like Figure 1 and Figure 2As shown, the inclined lifting mechanism 1 includes an inclined lifting frame 101, an inclined sliding groove 102 disposed on the inclined lifting frame 101, a first slider 103, a second slider 105, and a third slider 107 slidably connected from top to bottom in the inclined sliding groove 102, a guide wheel disposed on the top of the inclined lifting frame 101, and several traction machines disposed on the foundation. The output ends of the several traction machines are respectively connected to the first slider 103, the second slider 105, and the third slider 107 through a first traction rope 104, a second traction rope 106, and a third traction rope 108. The first slider 103 is provided with a through hole for the second traction rope 106 and the third traction rope 108 to pass through, and the second slider 105 is provided with a through hole for the third traction rope 108 to pass through. The first traction rope 104, the second traction rope 106, and the third traction rope 108 all pass around the guide wheel.

[0039] It should be noted that, as mentioned above, when adjusting the positions of the compaction mechanism 2, the attachment mechanism 3, and the clamping mechanism 4 using the inclined lifting mechanism 1, the corresponding traction ropes can be raised and lowered using the corresponding traction machine. For example, when adjusting the position of the compaction mechanism 2, the first traction rope 104 is raised and lowered using the corresponding traction machine. During the raising and lowering process, the first traction rope 104 can drive the first slider 103 to move along the inclined sliding groove 102. During the movement of the first slider 103, the perforation provided on it allows the second traction rope 106 and the third traction rope 108 to pass through, without driving the second traction rope 106 and the third traction rope 108 to move together. Similarly, when adjusting the position of the second slider 105, the second slider 105 will not drive the third traction rope 108 to move.

[0040] like Figure 1 and Figure 2 As shown, the compaction mechanism 2 includes a first hydraulic cylinder 201 movably connected to the first slider 103, a pressure plate 202 connected to the output end of the first hydraulic cylinder 201, a steering motor fixedly connected to the first slider 103, a first gear connected to the movable shaft connecting the first hydraulic cylinder 201 and the first slider 103, and a second gear connected to the output end of the steering motor. The first gear and the second gear mesh with each other.

[0041] It should be noted that the first hydraulic cylinder 201 moves along the inclined sliding groove 102 following the first slider 103. When it moves to the corresponding position of the roadbed slope, the second gear is driven to rotate by the steering motor. When the second gear rotates, it can drive the first gear to rotate. When the first gear rotates, it drives the first hydraulic cylinder 201 to rotate in the same direction and at the same angle. The angle between the first hydraulic cylinder 201 and the horizontal plane can be adjusted to adapt to the inclination of the corresponding position of the roadbed slope. Then, the first hydraulic cylinder 201 drives the pressure plate 202 to move toward the roadbed slope and compacts the slope with a certain pressure.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, the attachment mechanism 3 includes a second hydraulic cylinder 301 connected to the second slider 105, a first connecting frame 302 connected to the output end of the second hydraulic cylinder 301, and a first roller 303 movably connected to the first connecting frame 302. The first roller 303 contacts the top surface of the first pressing plate 501 or the second pressing plate 502.

[0043] It should be noted that initially, when the first hydraulic cylinder 201 drives the pressure plate 202 to compact the junction of the slope and the foundation, one end of the spliced ​​compaction mechanism 5 covers the compacted slope area. This end can be either the first compaction plate 501 or the second compaction plate 502, depending on the actual assembly sequence, but it does not affect the function of the spliced ​​compaction mechanism 5. Then, the first compaction plate 501 or the second compaction plate 502 is fixed to the slope area by the auxiliary positioning mechanism 7. Specifically, the limiting member passes through the first compaction plate 501 or the second compaction plate 502 and is driven into the foundation, whether or not it passes through the slope area, forming a stable limiting effect. At this time, the first compaction plate 501 or the second compaction plate 502... The bottom surface of 2 contacts the slope, and the top surface of the first roller 303 contacts the top surface of the first pressing plate 501 or the second pressing plate 502. When the second hydraulic cylinder 301 moves with the second slider 105, the first roller 303 can continuously apply pressure to the first pressing plate 501 or the second pressing plate 502 that will be covered on the slope, so that the corresponding first pressing plate 501 or the second pressing plate 502 is pressed on the corresponding area on the slope. During this process, the position of the first roller 303 can be adjusted by the second hydraulic cylinder 301 so that it is not blocked by the first hinge 503 or the second hinge 504. During this process, the clamping mechanism 4 continuously releases the subsequent first pressing plate 501 or the second pressing plate 502.

[0044] like Figure 1 , Figure 2 and Figure 4 As shown, the clamping mechanism 4 includes a third hydraulic cylinder 401 connected to the third slider 107, a second connecting frame 402 connected to the output end of the third hydraulic cylinder 401, a second roller 403 movably connected to the second connecting frame 402, a limiting groove 404 provided on the second connecting frame 402, a fourth slider slidably connected in the limiting groove 404, a third roller 405 movably connected to the fourth slider, and a spring 406 connected between the fourth slider and the inner wall of the limiting groove 404. When the third roller 405 contacts the first hinge 503 or the second hinge 504, the spring 406 is in a compressed state, and the second roller 403 contacts the bottom end face of the first pressing plate 501 or the second pressing plate 502.

[0045] It should be noted that the first pressing plate 501 or the second pressing plate 502 is clamped between the second roller 403 and the third roller 405. The third roller 405 can move along the limiting groove 404 toward or away from the second roller 403 to accommodate the first hinge 503 or the second hinge 504 passing through the area between the second roller 403 and the third roller 405. This allows the first pressing plate 501 or the second pressing plate 502 that is not pressed to be continuously released and gradually pressed onto the slope by the first roller 303, thus achieving the effect of automated laying.

[0046] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, when an outward-protruding turning angle appears on the roadbed slope, the sidewalls of the first pressing plate 501 and the second pressing plate 502 at the corresponding positions are provided with inclined cutting surfaces. When the inclined cutting surfaces on the first pressing plate 501 and the second pressing plate 502 contact and form a limiting effect, the angle between the first pressing plate 501 and the second pressing plate 502 is the same as the outward-protruding turning angle on the roadbed slope.

[0047] When a concave turning angle appears on the roadbed slope, right-angled trapezoidal supplementary material is welded to the sidewalls of the first pressing plate 501 and the second pressing plate 502 at the corresponding positions. When the right-angled trapezoidal material on the first pressing plate 501 contacts the right-angled trapezoidal supplementary material on the second pressing plate 502 and forms a limiting effect, the angle between the first pressing plate 501 and the second pressing plate 502 is the same as the concave turning angle on the roadbed slope.

[0048] It should be noted that cutting or welding the sidewalls of the first pressing plate 501 and the second pressing plate 502 that are in contact are all for the purpose of ensuring the continuity of the connection between the first pressing plate 501 and the second pressing plate 502. This allows the included angle between the first pressing plate 501 and the second pressing plate 502, which are in a coplanar state, to be adjusted within a set range. Moreover, the cut material can be used to supplement the turning angles with the same angle but opposite protrusion directions, thereby improving the sealing between the first pressing plate 501 and the second pressing plate 502 and achieving a stable limiting function. As long as the first pressing plate 501 or the second pressing plate 502 at the beginning and end positions is limited and fixed, all the first pressing plates 501 and the second pressing plate 502 in the middle cannot be pushed open, thus achieving a stable pressing effect without the need for other auxiliary limiting devices.

[0049] like Figure 5 , Figure 6 and Figure 7As shown, the auxiliary positioning mechanism 7 includes several positioning rods 701, which are used to limit and fix the first pressing plate 501 or the second pressing plate 502 located at the bottom of the roadbed slope to the foundation.

[0050] It should be noted that when connecting the first pressing plate 501 or the second pressing plate 502 to the foundation using the positioning rod 701, the first pressing plate 501 or the second pressing plate 502 can be fixed by drilling holes in the corresponding first pressing plate 501, inserting the positioning rod 701 into the holes, and driving it into the foundation to a set depth. The tail end located on the slope can be pressed by the pressing plate 202 in the compaction mechanism 2, or fixed by the positioning rod 701. After the first pressing plate 501 or the second pressing plate 502 at the beginning and end are fixed, all the first pressing plates 501 and the second pressing plates 502 in the middle area will not be pushed open or deformed by the external force of the roadbed soil, resulting in a better overall pressing effect.

[0051] The above description of this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.

A highway high embankment construction device according to claim 5, characterized in that, When a concave turning angle appears on the roadbed slope, right-angled trapezoidal supplementary material is welded to the sidewalls of the first pressing plate (501) and the second pressing plate (502) at the corresponding positions. When the right-angled trapezoidal material on the first pressing plate (501) contacts the right-angled trapezoidal supplementary material on the second pressing plate (502) and forms a limiting effect, the angle between the first pressing plate (501) and the second pressing plate (502) is the same as the concave turning angle on the roadbed slope.

7. A highway high embankment construction device according to claim 6, characterized in that, The auxiliary positioning mechanism (7) includes several positioning rods (701), which are used to limit and fix the first pressing plate (501) or the second pressing plate (502) located at the bottom of the roadbed slope to the foundation.

8. A method for constructing a high embankment roadbed, characterized in that, The construction device for high embankment roadbeds as described in any one of claims 1-7 includes the following steps: Erect end face limiting template (6) and inclined lifting mechanism (1) to fill the area between the two end face limiting templates (6) or the existing roadbed and the end face limiting template (6). When the height is set, the slope is treated. The inclined lifting mechanism (1) drives the compaction mechanism (2) to move along the roadbed slope and compact the slope area it passes through. One end of the splicing pressing mechanism (5) is fixed on the foundation by the auxiliary positioning mechanism (7), and then the attaching mechanism (3) is driven to move along the roadbed slope by the inclined lifting mechanism (1). During the movement, the subsequent first pressing plate (501) and second pressing plate (502) are attached along the compacted slope surface. When an outward-protruding turning angle appears on the roadbed slope, the sidewalls of the first pressing plate (501) and the second pressing plate (502) at the corresponding position are cut, and an inclined cutting surface is formed at the cut. When the inclined cutting surface on the first pressing plate (501) and the inclined cutting surface on the second pressing plate (502) come into contact and form a limiting effect, the angle between the first pressing plate (501) and the second pressing plate (502) is the same as the outward-protruding turning angle on the roadbed slope. The cut right-angled trapezoidal material is ready for use. When a concave turning angle appears on the roadbed slope, the cut right-angled trapezoidal material is welded to the side wall of the first pressing plate (501) and the second pressing plate (502) at the corresponding position. When the right-angled trapezoidal material on the first pressing plate (501) contacts the right-angled trapezoidal material on the second pressing plate (502) and forms a limiting effect, the angle between the first pressing plate (501) and the second pressing plate (502) remains the same as the concave turning angle on the roadbed slope. The process continues until the entire splicing compaction mechanism (5) completely covers the slope area, and the parallel surface area of ​​the roadbed is compacted.
