Description

Technical Field

[0001] This application relates to the technical field of road construction, and in particular to a construction device and method for concrete subbase construction of roads with steep slopes. Background Technology

[0002] Currently, many areas have steep terrain slopes, requiring the construction of roads with slopes greater than 5%. These steep roads are typically made of concrete, with the concrete subbase being a crucial component, serving to connect the roadbed and pavement, prevent water seepage, and transfer road loads.

[0003] In existing concrete subbase construction, it is usually carried out by a paver. The paver is usually equipped with a plate vibrator. After the material conveying mechanism of the paver spreads the concrete at the subbase, the plate vibrator is used directly to vibrate the subbase.

[0004] The aforementioned technologies have drawbacks. Due to the large slope of the concrete subbase, the concrete is prone to sliding and flowing after vibration, resulting in poor construction quality of the subbase and waste of construction materials. Summary of the Invention

[0005] In order to improve the construction quality of the subbase and reduce the waste of construction materials, this application provides a construction equipment and method for concrete subbase construction on steep roads.

[0006] Firstly, this application provides a construction device for concrete subbase layers on steeply sloping roads, employing the following technical solution:

[0007] A construction device for concrete subbase of roads with steep slopes includes a paver and a plate vibrator. A drying device is provided between the material conveying mechanism of the paver and the plate vibrator. The drying device includes a mounting frame on the paver and a drying fan for drying the concrete. The drying fan and the plate vibrator are arranged sequentially on the mounting frame along the travel direction of the paver.

[0008] By adopting the above technical solution, a drying device is installed between the material conveying mechanism and the plate vibrator. After the material conveying mechanism spreads the concrete, the drying fan is started to accelerate the solidification of the concrete. After the concrete has initially set, the plate vibrator works to vibrate the concrete subbase. At this time, the concrete is less likely to slide or flow, which can improve the construction quality of the subbase and reduce the waste of construction materials. At the same time, by constructing the steep road in sections, the phenomenon of reduced plasticity of concrete after a long solidification time and subsequent vibration causing internal damage and cracks in the concrete can be reduced.

[0009] Optionally, the mounting frame includes a mounting plate disposed on the paver and a sliding plate slidably fitted on the mounting plate, the drying fan is mounted on the mounting plate, and the plate vibrator is disposed on the sliding plate.

[0010] By adopting the above technical solution, during the paving process, the paver drives the drying fan and plate vibrator forward. The plate vibrator performs one vibration. After the first vibration is completed, the sliding plate slides outward to the farthest position of the mounting plate and then slides inward to the mounting plate. At this time, the plate vibrator moves to the bottom of the steep road and performs a second vibration, which makes the vibration effect of the steep road better.

[0011] Optionally, the mounting plate is provided with an adjustment device, which includes a connecting plate mounted on the sliding plate and a driver for pushing the sliding plate to slide and adjust within the mounting plate. One end of the driver is connected to the mounting plate, and the other end is connected to the connecting plate.

[0012] By adopting the above technical solution and adjusting the device, starting the driver can drive the connecting plate to move, which in turn drives the sliding plate to slide and adjust within the mounting plate, thus achieving adjustment of the sliding plate and making the operation convenient.

[0013] Optionally, a buffer is provided between the sliding plate and the plate vibrator to buffer the vibration generated when the plate vibrator is working.

[0014] By adopting the above technical solution and setting the buffer, the vibration generated by the plate vibrator during operation can be buffered by the buffer, reducing the rigid collision between the plate vibrator and the sliding plate, which would otherwise damage the sliding plate and the plate vibrator.

[0015] Optionally, the sliding plate is provided with a guiding device, which includes a guide sleeve installed on the sliding plate and a guide rod installed on the plate vibrator and slidably fitted inside the guide sleeve. One end of the buffer is installed on the sliding plate and the other end is installed on the top of the guide rod.

[0016] By adopting the above technical solution and setting the guide device, the plate vibrator can drive the guide rod to adjust within the guide sleeve when it is working, thereby limiting the movement of the buffer and reducing the phenomenon of irreversible deformation of the buffer.

[0017] Optionally, the bottom end of the guide sleeve is provided with a limiting part for limiting the sliding of the guide rod outward from the guide sleeve.

[0018] By adopting the above technical solution and setting the limiting part, the guide rod can be limited, which can reduce the occurrence of the guide rod slipping out of the guide sleeve.

[0019] Optionally, the paver is equipped with a rotating device, which includes a support frame mounted on the paver and a rotating assembly mounted on the support frame for driving the mounting plate to rotate, wherein the mounting plate is rotatably fitted onto the support frame.

[0020] By adopting the above technical solution, the rotating component can be activated to drive the mounting plate to rotate, thereby achieving the folding of the mounting plate and reducing the space occupied by the mounting plate on the paver.

[0021] Optionally, the rotating assembly includes a slider that slides along the height direction of the paver on the support frame, a second driver for driving the slider to rise and fall, and a rotating rod, one end of which is rotatably engaged with the slider and the other end of which is rotatably engaged with the mounting plate.

[0022] By adopting the above technical solution, starting the second driver can drive the slider to rise and fall, thereby driving the rotating rod to rotate and realize the rotation of the mounting plate, which is convenient to operate.

[0023] Optionally, the support frame is slidably fitted onto the paver in the vertical direction, and the paver is equipped with a lifting device for driving the support frame to rise and fall.

[0024] By adopting the above technical solution and setting up a lifting device, after the plate vibrator completes the first vibration, the lifting device is activated to drive the support frame to rise, and then drive the plate vibrator to rise. This reduces the contact between the plate vibrator and the concrete on the road during the movement of the plate vibrator to the bottom of the road, which would otherwise result in poor flatness of the concrete subbase. At the same time, when the plate vibrator needs to be vibrated a second time, the lifting device is used to drive the plate vibrator down to the road for secondary vibration operation.

[0025] Secondly, a method for constructing a concrete subbase for roads with steep slopes, utilizing the aforementioned equipment for constructing a concrete subbase for roads with steep slopes, comprising the following:

[0026] Paving: Using a paver to pave concrete on a steep road surface to be poured, and pouring the concrete from the lowest point of the steep slope to the highest point.

[0027] Drying: During the concrete pouring process, the drying fan is started to dry the poured concrete and accelerate its setting.

[0028] Vibration: After the concrete has initially set, a plate vibrator is used to vibrate the concrete subbase. Then, any uneven or insufficiently thick areas of the concrete subbase are repaired.

[0029] By adopting the above technical solution, when constructing roads with steep slopes, concrete is first laid on the steep slope. During the laying process, the concrete is dried by a drying fan. After the concrete has initially set, it is vibrated by a plate vibrator. This can improve the construction quality of the subbase and reduce the waste of construction materials.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] By installing a drying device between the material conveying mechanism and the plate vibrator, the drying fan is started after the material conveying mechanism spreads the concrete. The drying fan can accelerate the solidification of the concrete. After the concrete has initially set, the plate vibrator works and vibrates the concrete subbase. At this time, the concrete is less likely to slide and flow, which can improve the construction quality of the subbase and reduce the waste of construction material resources.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0038] This application discloses an apparatus for constructing concrete subbase layers for roads with steep slopes. (Refer to...) Figure 1 and Figure 2The system includes a paver 1 and multiple plate vibrators 2. Three plate vibrators 2 are arranged along the width of the paver 1. The material conveying mechanism 11 of the paver 1 is located on the side of the paver 1 away from the plate vibrators 2. A drying device 3 is installed between the material conveying mechanism 11 and the plate vibrators 2. The drying device 3 is used to dry the concrete subbase. When the concrete subbase needs to be constructed, the steep road is constructed in sections. The paver moves upward from the bottom of the steep road. During the forward movement of the paver, the material conveying mechanism 11 delivers concrete to the road and lays it. During the paving process, the drying device 3 is activated to dry the concrete. At the same time, the plate vibrators 2 are activated to perform a first vibration operation on the dried concrete subbase. After the first vibration operation is completed, a second vibration operation is performed. After the second vibration operation is completed, the concrete subbase is leveled. Then, the next section of the steep road is constructed in the same way.

[0039] Among them, reference Figure 1 and Figure 2 The drying device 3 includes a mounting frame 31 mounted on the paver 1 and a drying fan 32 for drying concrete. The drying fan 32 and the plate vibrator 2 are sequentially mounted on the mounting frame 31 along the travel direction of the paver 1. The mounting frame 31 includes a mounting plate 311 mounted on the paver 1 and a sliding plate 312 slidably fitted on the mounting plate 311. A groove is provided in the mounting plate 311. One end of the sliding plate 312 extends into the groove and slides with the groove. The drying fan 32 is fixedly mounted on the mounting plate 311, and three are spaced apart along the width direction of the paver 1. The plate vibrator 2 is mounted on the sliding plate 312. A scraper plate 9 is fixedly mounted on the end of the sliding plate 312 away from the mounting plate 311. The scraper plate 9 is an L-shaped plate and is used to scrape the concrete subbase.

[0040] Reference Figure 1 and Figure 2 An adjustment device 4 is provided on the mounting plate 311. The adjustment device 4 includes a connecting plate 41 fixedly mounted on the sliding plate 312 and a driver 42 for pushing the sliding plate 312 to slide and adjust within the mounting plate 311. The driver 42 can be a hydraulic cylinder. One end of the driver 42 is fixedly connected to the mounting plate 311 and the other end is fixedly connected to the connecting plate 41.

[0041] Reference Figure 1 and Figure 2When the paver 1 is working, the sliding plate 312 is located inside the mounting plate 311. During the paving process, the plate vibrator 2 vibrates the concrete subbase once. After the first vibration is completed, the driver 42 is started, and the sliding plate 312 is driven out of the mounting plate 311 through the connecting plate 41 and slides to the bottom of the concrete subbase. Then the plate vibrator 2 is started to vibrate the concrete subbase a second time. At the same time, the driver 42 drives the sliding plate 312 and the plate vibrator 2 to slide into the mounting plate 311.

[0042] Reference Figure 3 and Figure 4 To reduce the risk of damage to both the plate vibrator 2 and the sliding plate 312 due to rigid collisions during operation, a buffer 5 is provided between the sliding plate 312 and the plate vibrator 2. The buffer 5 is used to buffer the vibrations generated during the operation of the plate vibrator 2, and the buffer 5 can be a spring. A guide device 6 is provided on the sliding plate 312. The guide device 6 includes a guide sleeve 61 fixedly installed on the sliding plate 312 and a guide rod 62 fixedly installed on the plate vibrator 2. The guide rod 62 has a T-shaped structure and slides within the guide sleeve 61. A limiting part 611 is provided at the bottom end of the guide sleeve 61 to limit the sliding of the guide rod 62 outward from the guide sleeve 61.

[0043] Reference Figure 3 and Figure 4 One end of the buffer 5 is fixedly installed on the sliding plate 312, and the other end is fixedly installed on the top of the guide rod 62. When the plate vibrator 2 is working, it can drive the guide rod 62 to slide inside the guide sleeve 61, and buffer the vibration generated by the plate vibrator 2 during operation through the buffer 5.

[0044] Reference Figure 1 and Figure 2 To facilitate the folding and storage of the mounting frame 31, a rotating device 7 is installed on the paver 1. The rotating device 7 includes a support frame 71 that slides vertically on the paver 1 and a rotating assembly 72 mounted on the support frame 71. The support frame 71 includes an L-shaped rod that slides on the paver 1, a slide rail fixedly mounted on the L-shaped rod, and a U-shaped plate fixedly mounted on the slide rail. The mounting plate 311 is rotatably mounted on the U-shaped plate of the support frame 71, and when the mounting plate 311 is rotated to a horizontal position, the lower surface of the mounting plate 311 abuts against the U-shaped plate of the support frame 71. A guide plate 10 is fixedly mounted on the paver 1. The guide plate 10 has a U-shaped structure, and the slide rail of the support frame 71 slides within the guide plate 10.

[0045] Among them, reference Figure 1 and Figure 2The rotating assembly 72 is used to drive the mounting plate 311 to rotate, combined with Figure 3 The rotating assembly 72 includes a slider 721 that slides along the height of the paver 1 on a support frame 71, a second driver 722 for driving the slider 721 to rise and fall, and a rotating rod 723. The second driver 722 can be a hydraulic cylinder, and the cylinder body of the second driver 722 is fixedly mounted on an L-shaped rod of the support frame 71. The slider 721 is a T-shaped block, and the piston rod of the second driver 722 is fixedly connected to the slider 721. Rotating seats are installed at both ends of the rotating rod 723. One end of the rotating rod 723 is rotatably engaged with the slider 721 through the rotating seat, and the other end is rotatably engaged with the mounting plate 311 through the rotating seat.

[0046] Reference Figure 1 and Figure 2 When the mounting frame 31 needs to be folded and stored, first slide the sliding plate 312 into the mounting plate 311, then start the second driver 722, drive the slider 721 to rise, drive the rotating rod 723 to rotate, drive the mounting plate 311 to rotate, the end of the mounting plate 311 away from the paver 1 to rotate towards the paver 1, and rotate from the horizontal position to the vertical position, thus completing the folding and storage of the mounting frame 31.

[0047] Reference Figure 1 and Figure 2 The paver 1 is equipped with a lifting device 8, which is used to raise and lower the support frame 71. The lifting device 8 includes a fixed frame 81 fixedly installed on the paver 1 and a driver 82 fixedly installed on the fixed frame 81. The driver 82 can be a hydraulic cylinder, with the cylinder body fixedly installed on the fixed frame 81 and the piston rod of the driver 82 fixedly connected to the support frame 71. Activating the driver 82 sequentially raises and lowers the support frame 71 and the mounting frame 31, thereby raising and lowering the plate vibrator 2. This allows the plate vibrator 2 to better compact the concrete subbase. After the plate vibrator 2 completes one compaction cycle, the driver 82 raises the support frame 71 and the plate vibrator 2. After moving from the top to the bottom of the steep road, the driver 82 lowers the support frame 71 and the plate vibrator 2, thus continuing the compaction of the concrete subbase.

[0048] The implementation principle of a concrete subbase construction equipment for steep road surfaces according to an embodiment of this application is as follows: When concrete subbase construction is required, the rotating device 7 is first started, driving the mounting frame 31 to rotate from a vertical position to a horizontal position. Then, the paver 1 is started, and the concrete is transported to the road through the material conveying mechanism 11 for paving. During the paving operation, the drying device 3 is started to dry the concrete subbase. At the same time, the plate vibrator 2 is started to vibrate the initially set concrete subbase once. After the first vibration operation of the concrete subbase, the lifting device 8 and the adjusting device 4 are started to adjust the position of the plate vibrator 2 so that the plate vibrator 2 moves from the top to the bottom of the steep road. Then, the plate vibrator 2 is started to vibrate the concrete subbase a second time. At the same time, the adjusting device 4 is started to move the plate vibrator 2 towards the paver 1. The steep road is constructed in sections in the same manner.

[0049] Please refer to Figure 1 and Figure 2 This application also provides a method for constructing concrete subbase layers for roads with steep slopes, as shown in the figure. This construction method utilizes the aforementioned construction equipment, specifically including the following:

[0050] Paving: Use paver 1 to pave concrete on the steep road surface to be poured, and pour the concrete from the lowest point of the steep road surface to the highest point.

[0051] Drying: During the concrete pouring process, the drying fan 32 is started to dry the poured concrete and accelerate its solidification.

[0052] Vibration: After the concrete has initially set, use a plate vibrator 2 to vibrate the concrete subbase. Then, repair any uneven or insufficiently thick areas in the concrete subbase.

[0053] When constructing a concrete subbase for a steep road, the concrete is first laid using a paver 1, then dried using a drying device 3. After the concrete has initially set, it is compacted using a plate vibrator 2, and the flatness of the concrete subbase is adjusted to complete the construction of the concrete subbase. The specific implementation principle of this method has been described in detail in the above embodiments, and therefore will not be repeated here.
