Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a deep foundation pit backfill soil leveling device. Background Technology

[0002] A deep foundation pit is an earthen pit dug during the construction process. The building foundation is built in the foundation pit to form a supporting foundation. Therefore, after the foundation is completed, the space inside the deep foundation pit needs to be backfilled. Materials such as soil and silt are injected into the deep foundation pit, and then the backfill soil is repeatedly compacted with a leveling device to achieve sufficient density. The compaction device is generally a road roller.

[0003] However, conventional compaction devices only apply pressure to the backfill soil by rolling the compaction roller. As a result, clay material easily adheres to the surface of the compaction roller. After long-term use, a large amount of debris will adhere to the surface of the compaction roller, affecting the subsequent leveling effect. At the same time, the single rolling compaction method needs to be repeated many times, resulting in low construction efficiency. It may even require the use of other types of compaction equipment to achieve the purpose of compaction, which increases the additional equipment cost. Summary of the Invention

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] Please see Figures 1 to 5 This invention provides a technical solution: a deep foundation pit backfill soil leveling device, comprising a leveling device body, the leveling device body including a frame 1, a first leveling mechanism 3, a cleaning mechanism 4, and a second leveling mechanism 6. A traction fixing member 2 is installed on the top of the frame 1, and the frame 1 is connected to an external traction vehicle via the traction fixing members 2 on both sides. The first leveling mechanism 3 is installed inside the frame 1, and a drive shaft 10 is provided inside the first leveling mechanism 3. The two ends of the drive shaft 10 are movably connected to the inner wall of the side plate of the frame 1. The bottom end of the first leveling mechanism 3 is in direct contact with the ground. Both ends of the device are equipped with transmission components 5. A cleaning mechanism 4 is provided on the top of the transmission components 5. A second flattening mechanism 6 is provided on the side of the cleaning mechanism 4. A lifting sleeve 7 is provided on the top of the second flattening mechanism 6. The top of the lifting sleeve 7 is welded to the top of the frame 1 as a whole. The deep foundation pit backfill soil flattening device is connected to an external traction vehicle at the top through a traction fixing component 2. The device can be moved on the surface of the backfilled deep foundation pit by an external power device. During the movement, the surface of the backfill soil is compacted by the first flattening mechanism 3 and the second flattening mechanism 6 at the bottom of the device.

[0027] In this embodiment, the first flattening mechanism 3 includes a drive shaft 10 and a compaction roller 8. The compaction roller 8 is sleeved on the surface of the drive shaft 10. Both ends of the compaction roller 8 are equipped with drive gears 9, and the first flattening mechanism 3 is partially connected to the transmission assembly 5 through the drive gears 9. Both ends of the drive shaft 10 are sleeved with bearings, and the drive shaft 10 is embedded in the inner wall of the frame 1 through the bearings. The drive shaft 10, the compaction roller 8, and the drive gears 9 are all connected by keys. After being connected to an external traction engineering vehicle through the top traction fixing component 2, it can start working. This device provides two compaction methods: rolling flattening and impact flattening. Both can be achieved simultaneously by being pushed by an external traction vehicle, which improves the compaction efficiency and reduces the overall cost of the equipment. It has high synchronization and improves the efficiency of flattening construction. Specifically, during operation, the compaction roller 8 contacts the ground. As the external traction vehicle moves, it can push the entire compaction roller 8 to roll along a preset route. During the rolling process, the compaction effect on the ground is achieved by the self-weight of the compaction roller 8.

[0028] In this embodiment, the transmission assembly 5 includes a transmission gear 11 and an extension sprocket 12. Both the transmission gear 11 and the extension sprocket 12 are mounted on a transmission shaft 13. A bracket 14 is provided at the rear end of the transmission shaft 13. A chain 17 is mounted on the surface of the extension sprocket 12, and the transmission assembly 5 is partially connected to the cleaning mechanism 4 via this chain 17. The transmission gear 11 and the extension sprocket 12 are welded together as a whole, and the inner sides of the transmission gear 11 and the extension sprocket 12 are mounted on the surface of the transmission shaft 13 via bearings. The bracket 14 and the transmission shaft 13... The ends are all welded and installed on the inner wall of the frame 1. As the first flattening mechanism 3 rotates, the drive gear 11 is driven to rotate through the active gears at both ends. The drive gear 11 and the extension sprocket 12 rotate synchronously, and then the driven sprocket 16 is driven by the chain 17. The driven sprocket 16 makes the support roller 18 rotate. The surface of the support roller 18 is fixedly connected to the hollow roller 20 through multiple support rods 19. Therefore, the hollow roller 20 can rotate, and the brush 21 on the surface of the roller 8 can be brushed and cleaned, thus playing a self-cleaning role.

[0029] In this embodiment, the cleaning mechanism 4 includes a support roller 18 and a brush 21. A driven shaft 15 is inserted inside the support roller 18. A lever 22 is welded to the surface of the support roller 18, and the lever 22 contacts the side of the second flattening mechanism 6. A support rod 19 is welded to the surface of the support roller 18, and a hollow roller 20 is provided at the end of the support rod 19. The brush 21 is inserted into the surface of the hollow roller 20. Driven sprockets 16 are provided at both ends of the support roller 18, and the top of the chain 17 is sleeved on the surface of the driven sprockets 16. The edge of the brush 21 contacts the surface of the rolling roller 8. The cleaning mechanism 4 is driven by the transmission component 5 in the middle. Therefore, the cleaning mechanism 4 can continuously clean the surface of the first flattening mechanism 3 during the entire operation of the device, so as to avoid the situation where a large amount of mud adheres to the surface of the rolling roller 8, which would lead to a poor subsequent flattening effect and improve the flattening quality. It can also be automatically achieved with the construction operation. When the cleaning mechanism 4 rotates, it will scrape off the protrusions adhering to the surface of the rolling roller 8 towards the front end. Therefore, the scraped protrusions can be rolled and compacted again by the rolling roller 8.

[0030] In this embodiment, the second flattening mechanism 6 includes a telescopic rod 23 and an impact plate 27. A stop bar 24 is welded to the side of the telescopic rod 23, and a docking sleeve 25 is provided at the bottom end of the telescopic rod 23. A groove 26 is formed on the inner side of the docking sleeve 25, and a steel ball 29 is embedded at the bottom end of the groove 26. A docking rod 28 is welded to the top of the impact plate 27 and passes through the inside of the groove 26. The bottom end of the docking rod 28 is set with an arc-shaped structure. The top of the telescopic rod 23 is inserted into the inside of the lifting sleeve 7. The second flattening mechanism 6 achieves a sliding connection through the bottom docking rod 28 and the docking sleeve 25. Therefore, when the second flattening mechanism 6 impacts the ground, the first flattening mechanism 3 at the rear end and the external traction vehicle continue to run. During this time, the second flattening mechanism 6, which is in contact with the ground and remains fixed, will not affect the entire... The device and the traction vehicle create obstruction, thereby improving the smoothness of the tamping operation and minimizing resistance. As the support roller 18 rotates, the side lever 22 periodically pushes the stop bar 24 upward, causing the telescopic rod 23 to reciprocate inside the lifting sleeve 7. After each lever 22 shifts away from the stop bar 24, the telescopic rod 23 and the bottom impact plate 27 move downward, achieving an impact effect on the ground. Specifically, after the impact plate 27 contacts the ground, the entire compaction device continues to move forward. At this time, the impact plate 27 is in contact with the ground and therefore experiences greater resistance. As the compaction device moves forward or the top telescopic rod 23 and the connecting sleeve 25 slide forward a short distance along the connecting rod 28, the impact plate 27 does not transmit resistance to the entire device, thus achieving the effect of eliminating resistance after impact.
