Description

Technical Field

[0001] This invention relates to the technical field of roadbed construction, specifically to a roadbed treatment structure and construction method in soft soil areas. Background Technology

[0002] Chinese patent document CN102493305A discloses a roadbed treatment structure for soft soil areas. The structure is built on a subgrade and consists of a 60-80 cm layer of topsoil support, a lime-soil conditioning layer, and a pavement structure layer, arranged sequentially from bottom to top. The lime-soil conditioning layer has a lime content of 8% to 10%. The roadbed treatment structure also includes at least one drainage channel, which also serves as a pipeline channel. This invention also discloses the construction process of this roadbed treatment structure. By increasing the lime content in the lime-soil, this invention enhances the strength of the lime-soil conditioning layer, eliminates the need for a crushed stone waterproofing layer, and lowers the road design elevation. This reduces the amount of earthwork and lowers project investment while ensuring the strength and stability of the roadbed. The appropriately increased lime content also contributes to the overall strength of the pavement and improves the stability of the roadbed under groundwater freeze-thaw cycles, thus enhancing the overall stability of the pavement.

[0003] However, in the above-mentioned solutions and existing technologies, the roadbed treatment process in soft soil areas requires multiple compaction processes using a road roller. During the operation of the road roller, if there are debris in the soil layer, the road roller will press these debris into the ground, affecting the aesthetics of the roadbed. Harder debris can damage the roller roller and affect the operation of the road roller.

[0004] Therefore, we need a roadbed treatment structure and construction method for soft soil areas to solve the problem of debris in the existing roadbed soil affecting the operation of road rollers. Summary of the Invention

[0031] Example 1

[0032] A roadbed treatment structure for soft soil areas includes a frame 1, a roller 2, a bucket 3, a material collection assembly, and a cleaning assembly. The frame 1 is mounted on a road roller, and the roller 2 is installed on the frame 1. A mounting frame 4 is symmetrically fixed to the upper end of the frame 1, and a hydraulic cylinder 5 is fixedly mounted on the mounting frame 4. The output end of the hydraulic cylinder 5 is fixedly connected to the bucket 3. The bucket 3 has a matrix of perforations 6 and is located at the front end of the frame 1. The material collection assembly and the cleaning assembly are mounted on the bucket 3. In actual use, the hydraulic cylinder 5 is operated to control the lifting and lowering of the bucket 3. As the road roller moves, debris in front of the roller 2 is collected by the bucket 3, and broken soil leaks out through the perforations 6. The roller 2 flattens and compacts the roadbed in the soft soil area. Furthermore, it collects debris from the roadbed soil layer, solving the problem of debris in the roadbed soil layer affecting the operation of the road roller.

[0033] Example 2, based on Example 1:

[0034] The receiving assembly includes a first rotating shaft 7, a fixing rod 8, a threaded groove 9, a mounting tube 10, a threaded hole 11, an arc block 12, brush strips 13, brush balls 14, and a first motor 15. The first rotating shaft 7 is rotatably connected at both ends to the inner wall of the bucket 3. Fixing rods 8 are equidistantly and annularly fixed on the first rotating shaft 7, and threaded grooves 9 are formed on the fixing rods 8.

Threaded holes 11 are formed on the side wall of the mounting tube 10, and threaded grooves 9 and threaded holes 11 are positioned correspondingly and have the same number of sets, and are fixedly connected by screws. An arc block 12 is fixedly mounted at the end of the mounting tube 10, and brush strips 13 are evenly distributed and fixedly mounted on the arc block 12. Brush balls 14 are fixedly mounted at the ends of the brush strips 13. The brush strip 13 and brush ball 14 are engaged with the bottom side wall of the bucket 3; the first motor 15 is fixedly mounted on the outer side wall of the bucket 3, and the output shaft of the first motor 15 passes through the side wall of the bucket 3 and is fixedly connected to the first rotating shaft 7; in actual use, the bucket 3 is pushed up by the road roller to scoop up debris in the subgrade soil layer. The first motor 15 starts and drives the first rotating shaft 7 to rotate. The brush strip 13 and brush ball 14 sweep the debris scooped up by the bucket 3 into the inside of the bucket 3 as the fixed rod 8 rotates. After long-term use, the brush strip 13 and brush ball 14 will have some wear. At this time, the screws at the threaded groove 9 and threaded hole 11 are unscrewed, and the fixed rod 8 and the mounting tube 10 are separated to replace the brush strip 13 and brush ball 14; further collecting the debris in the subgrade soil layer solves the problem of debris in the subgrade soil layer affecting the operation of the road roller.

[0035] The remaining technical features and effects of this embodiment are the same as those of Embodiment 1.

The scraper 25 is engaged with the roller 2. Baffles 26 are symmetrically fixed on both sides of the slide plate 23. In actual use, the brush strip 13 and brush ball 14 sweep the debris scooped up by the bucket 3 into the collection groove 16 inside the bucket 3. When the roller 2 is working, the surface is covered with mud. At this time, the scraper 25 will scrape off the mud on the surface of the roller 2. The mud falls from the discharge hole 22 along the slide plate 23 to the collection groove 16. Inside the trough 16, soil is prevented from adhering to the surface of the roller 2 again. The baffles 26 on both sides of the slide plate 23 prevent the scraped soil from falling off. After the roller completes one pass of roadbed leveling operation, the flip cover 18 at the discharge port 17 is opened, and the second motor 21 is started to drive the second rotating shaft 19 to rotate, so that the rotating spiral blades 20 discharge the debris and soil collected in the trough 16 from the discharge port 17; further collecting the debris in the roadbed soil layer, solving the problem that the debris in the roadbed soil layer affects the operation of the roller.

[0038] The remaining technical features and effects of this embodiment are the same as those of Embodiment 2.

[0040] The auxiliary components include a fixing block 27, a T-slot 28, a slot 29, a fixing plate 30, a push plate 31, a toothed groove 32, a T-block 33, a positioning block 34, a positioning hole 35, a slot 36, a sliding groove 37, a limiting block 38, an insert block 39, a slider 40, a round hole 41, and a spring 42. The fixing blocks 27 are symmetrically fixed on both sides of the mounting tube 10, and T-slots 28 are provided on the fixing blocks 27. Slots 29 are symmetrically provided on the side walls of the fixing rods 8. The fixing plate 30 is provided between adjacent fixing rods 8. A push plate 31 is fixedly provided at the bottom of the fixing plate 30. Toothed grooves 32 are provided at equal intervals on the side ends of the push plate 31. The two ends of the push plate 31 are symmetrically fixed. A T-shaped block 33 is provided; positioning blocks 34 are fixedly mounted on the fixed plate 30 in a matrix, and positioning holes 35 are provided on the positioning blocks 34; slots 36 are symmetrically opened in the fixed plate 30, and sliding grooves 37 are provided at the upper end of the slots 36. Limiting blocks 38 are movably engaged in the slots 36; springs 42 are provided in the slots 36, and the two ends of the springs 42 are engaged with the inner wall of the slots 36 and the limiting blocks 38 respectively; insert blocks 39 are fixedly mounted on the side of the limiting blocks 38 and penetrate the fixed plate 30; sliders 40 are fixedly mounted on the upper end of the limiting blocks 38 and have round holes 41; the T-shaped blocks 33 and T-shaped slots 28 are positioned correspondingly and are engaged.

At this time, the slider 40 is moved along the slide groove 37 to compress the spring 42, and then the T-shaped block 33 is aligned with the T-shaped groove 28 and engaged to install the fixing plate 30 and push plate 31. Between the adjacent fixed rod 8, the slider 40 is released, and the spring 42 rebounds, pushing the limit block 38 to move so that the insert block 39 is inserted into the slot 29, fixing the position of the fixed plate 30 and the push plate 31. The bolts are inserted into the round hole 41 and the positioning hole 35 and the nuts are screwed in to prevent the slider 40 from moving. At this time, the push plate 31 moves simultaneously with the rotation of the fixed rod 8. The toothed groove 32 on the push plate 31 can hold the corners of larger stones and other debris, making it easier for the push plate 31 to sweep larger stones and other debris into the inside of the bucket 3. This further collects the debris in the subgrade soil layer, solving the problem that the debris in the subgrade soil layer affects the operation of the road roller.

At this time, the scraper (25) will push the roller (2) ( 2) The soil adhering to the surface is scraped off, and the soil falls from the drop hole (22) into the collection trough (16) along the slide plate (23) to avoid the soil adhering to the surface of the roller (2) again. After the roller completes one pass of roadbed leveling operation, the flip cover (18) at the discharge port (17) is opened, and the second motor (21) is started to drive the second rotating shaft (19) to rotate, so that the rotating spiral blades (20) discharge the debris and soil collected in the collection trough (16) from the discharge port (17).
