Description
Technical Field
[0001] This utility model relates to the field of bored pile technology, specifically a slag removal device for the bottom of a bored pile. Background Technology
[0002] Drilled cast-in-place piles are piles constructed by drilling a hole in situ and then filling it with concrete or reinforced concrete. Commonly used types include drilled cast-in-place piles, which are formed by drilling a hole in situ using auger drilling rigs or submersible drilling rigs and then filling it with concrete. Construction is vibration-free and does not cause soil displacement, but the pile settlement is slightly larger. During the construction of drilled cast-in-place piles, the drill cuttings at the bottom of the hole need to be effectively removed to ensure the quality and bearing capacity of the pile foundation. Traditional cuttings removal methods may suffer from low efficiency and high consumption of manpower and resources; therefore, the development of a drilled cast-in-place pile hole bottom cuttings removal device is particularly important.
[0003] However, existing borehole slag removal devices for bored piles still have some shortcomings: traditional manual slag removal is inefficient, makes it difficult to separate sediment from mud, and increases the mud circulation time. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bottom slag removal device for bored piles.

[0007] The drive motor is fixedly connected to the inner side of the fixed plate, and the rotating shaft is rotatably connected to the inner side of the fixed plate, and the winding wheel is fixedly connected to the rotating shaft.
[0008] As a further description of the above technical solution:

[0018] This utility model has the following beneficial effects:
[0019] 1. By starting the drive motor, the winding wheel rotates inside the fixed plate via the rotating shaft, causing the winding wheel to release the lifting rope. This allows the mud pump to descend to the inside of the cast-in-place pile, and the mud pump is started to extract the mud and slag mixture at the bottom of the cast-in-place pile. Compared with the traditional manual slag removal, this mechanized slag removal method can significantly improve cleaning efficiency and construction efficiency.

At the same time, the connecting hole 22 is connected to a second connecting hose 23, and the inner side of the second connecting hose 23 is connected to a filter screen 24, and the second connecting hose 23 is provided with a valve 25.
[0030] In this embodiment, the adjustment component 1 and the filter component 2 constitute a bottom slag removal device for a bored pile 114 according to this application, which realizes the operation of adjusting the height of the mud pump 19 and filtering the cement sand in the sedimentation bucket 21.
[0031] In this embodiment, the designed mud pump 19 is existing technology, which can extract the mud and sludge mixture at the bottom of the hole and transport it to a designated location through a pipeline, thereby achieving the cleaning and sludge removal of the bottom of the hole.
[0032] In this embodiment, by starting the drive motor 12, the winding wheel 13 is driven to rotate inside the fixed plate 11 via the rotating shaft 14, so that the winding wheel 13 performs the rope unwinding operation on the lifting rope 15.
[0033] It should be noted that by releasing the lifting rope 15 through the winding wheel 13, the mud pump 19 can be driven to descend to the inside of the cast-in-place pile 114.
[0034] Specifically, the drive motor 12 is fixedly connected to the inner side of the fixed plate 11, and the rotating shaft 14 is rotatably connected to the inner side of the fixed plate 11. The winding wheel 13 is fixedly connected to the rotating shaft 14. The lifting rope 15 is wound around the inner side of the winding wheel 13 and slides against the rotating wheel 16. One end of the lifting rope 15 is fixedly connected to the connecting plate 113. The rotating wheel 16 is rotatably connected to the transverse rod provided on the connecting ring 17. The connecting ring 17 is connected through the connecting block 18. The connecting block 18 is fixedly connected to the upper end of the mud pump 19. The connecting rigid pipe 110 is located away from the... One end of flange 111 is fixedly connected to one side of mud pump 19, and flange 111 is fixedly connected to one end of first connecting pipe 112. First connecting pipe 112 and connecting rigid pipe 110 are connected through flange 111. One end of second connecting hose 23 is fixedly connected to connecting hole 22. Filter screen 24 is fixedly connected to the inside of second connecting hose 23. Second connecting hose 23 is located on the lower side of sediment bucket 21. Mud pump 19 is slidably located on the inside of cast-in-place pile 114. The end of first connecting pipe 112 away from flange 111 is located directly above sediment bucket 21.
[0035] In a preferred embodiment, the mud and sludge mixture at the bottom of the cast-in-place pile 114 is extracted by starting the mud pump 19, and the mud and sludge mixture is transported to the sedimentation tank 21 by connecting the rigid pipe 110 and the first connecting pipe 112.
[0036] In a preferred embodiment, when the mud and sludge mixture enters the sedimentation tank 21, the valve 25 can be opened, and the mud and sludge mixture is filtered through the filter screen 24 to separate the sediment and mud. The mud is discharged through the second connecting hose 23.
[0037] In a preferred embodiment, when the line is released by the lifting rope 15, one lifting rope 15 passes through the rotating wheel 16, causing the rotating wheel 16 to rotate on the connecting ring 17.
[0038] It should be noted that when the mud pump 19 falls into the cast-in-place pile 114, the connecting rigid pipe 110 falls along with the mud pump 19, and the length of the first connecting pipe 112 is sufficient for the mud pump 19 to fall to the bottom of the cast-in-place pile 114. At the same time, the diameter of the cast-in-place pile 114 is sufficient for the mud pump 19 and the connecting rigid pipe 110 to extend into the cast-in-place pile 114 at the same time.
[0039] In a preferred embodiment, the fixing plate 11 is fixedly connected to a support column (not shown) provided on site to provide support for the mud pump 19 and the drive motor 12.
[0040] In use, by starting the drive motor 12, the take-up reel 13 is driven to rotate inside the fixed plate 11 via the rotating shaft 14, causing the take-up reel 13 to release the lifting rope 15. This drives the mud pump 19 to descend to the inside of the cast-in-place pile 114. By starting the mud pump 19, the mud and sludge mixture at the bottom of the cast-in-place pile 114 is extracted. The mud and sludge mixture is then transported to the sediment tank 21 through the connecting rigid pipe 110 and the first connecting pipe 112. By opening the valve 25, the mud and sludge mixture is filtered through the filter screen 24, separating the sediment and mud. The mud is discharged through the second connecting hose 23. By starting the drive motor 12, the take-up reel 13 is driven to rotate in the opposite direction, causing the lifting rope 15 to be wound up on the take-up reel 13. This allows the mud pump 19 to be pulled out of the cast-in-place pile 114.
[0041] This utility model discloses a bottom slag removal device for 114 boreholes of bored piles. Compared with traditional manual slag removal, it can significantly improve cleaning efficiency and construction efficiency, and can quickly separate sediment from mud, reducing the mud circulation processing time.
