[0002] In the field of construction engineering, pipe piles are widely used in various building structures as an important basic engineering component. However, during the construction of pipe piles, the compactness of the pipe pile hole wall has always been one of the key factors affecting the quality and safety of the project. The traditional method of processing the pipe pile hole wall mainly relies on manual operation and simple mechanical assistance. In the case of manually dug bored piles, workers usually use tools such as shovels and spades to trim and compact the hole wall, but this method is inefficient, labor-intensive, and it is difficult to ensure uniform compactness.

[0003] For mechanically bored pipe piles, although some drilling equipment can form the hole wall to a certain extent, due to the complexity and variability of geological conditions, the hole wall often has the risk of loosening and collapse.

A mounting groove is provided at the top of the mounting column 103, and a telescopic cylinder 104 is fixedly provided in the mounting groove. A lifting plate 102 is fixedly provided at the telescopic end of the telescopic cylinder 104. The lifting plate 102 and the upper ring plate 105 are connected by a connecting component, and also include: a traction mechanism, which is arranged above the mounting plate 101 and is used to pull the lifting plate 102 up and down to move in the pile hole to be compacted; a supporting mechanism, which is arranged below the mounting plate 101 and is used to erect the mounting plate 101 above the pile hole to be compacted.

[0028] The mounting plate 101 can be erected above the pile hole to be tightened by a supporting mechanism, and the lifting plate 102 and the mounting column 103 can be lowered to the bottom of the pile hole by a traction mechanism, and then the lifting plate 102 can be driven to move upward by the telescopic cylinder 104, and the lifting plate 102 can drive the upper ring plate 105 to move upward on the outside of the mounting column 103 by the connecting assembly. Since the upper ring plate 105 and the lower ring plate 107 are connected by a fixing rod 106, the lower ring plate 107 can move upward together with the upper ring plate 105. During the process of the lower ring plate 107 and the upper ring plate 105 moving upward together, The scraper 110 will be driven to rotate around the fixed ring 109 through the connecting rod 108, so that the end of the scraper 110 away from the fixed ring 109 is in close contact with the hole wall of the pile hole, and then the lifting plate 102 is driven to move up by the traction mechanism, so that the scraper 110 can sweep the hole wall to compact the hole wall, and the adjacent scrapers 110 are staggered so that the hole wall in the pile hole can be scraped.

When the vertical plate 401 remains in an upright state, the universal wheel 403 contacts the ground, which facilitates the flexible movement of the position of the device. When the mounting plate 101 moves to the top of the pile hole to be tightened, the vertical plate 401 can be rotated so that the vertical plate 401 is unfolded to both sides and fits with the mounting plate 101, and the plug 404 on one side of the supporting plate 402 is inserted into the ground, which can play a role in stably supporting the mounting plate 101, and the use effect is better.

At this time, the grip rod 407 can be held and the nut 406 can be rotated so that the nut 406 is in contact with the upper surface of the mounting plate 101, which can lock the mounting plate 101 and the vertical plate 401, so that the vertical plate 401 is more stable when supporting the mounting plate 101, and the use effect is better.

[0035] When in use, the mounting plate 101 can be erected above the pile hole to be tightened by a supporting mechanism, and the lifting plate 102 and the mounting column 103 are lowered to the bottom of the pile hole by a traction mechanism, and then the lifting plate 102 can be driven to move upward by the telescopic cylinder 104, and the lifting plate 102 can drive the upper ring plate 105 to move upward on the outside of the mounting column 103 by the connecting assembly. Since the upper ring plate 105 and the lower ring plate 107 are connected by a fixing rod 106, the lower ring plate 107 can move upward with the upper ring plate 105, and the lower ring plate 107 moves upward together with the upper ring plate 105. In the process, the scraper 110 will be driven to rotate around the fixed ring 109 through the connecting rod 108, so that the end of the scraper 110 away from the fixed ring 109 is in close contact with the hole wall of the pile hole, and then the lifting plate 102 is driven to move up by the traction mechanism, so that the scraper 110 can sweep the hole wall to compact the hole wall, and the adjacent scrapers 110 are staggered so that the hole wall in the pile hole can be scraped.
