Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a method for detecting and treating sediment at the pile tip. Background Art

[0002] Sediment at the pile tip refers to soil, gravel or other impurities accumulated under the pile tip during the construction of pile foundations, especially during the construction of driven piles or bored piles. The existence of sediment may affect the bearing capacity and construction quality of the pile foundation. Therefore, special attention needs to be paid during the construction and design of piles. The detection and treatment of sediment at the pile tip are key links to ensure the quality of pile foundations. Through effective detection means, sediment problems can be detected in time and corresponding treatment measures can be taken to ensure the stability and safety of the pile foundation.

[0003] A Chinese patent with the publication number CN111677019A discloses a method for detecting and treating sediment at the pile tip, including a pile body. A sediment detection and treatment device at the pile tip is provided at the bottom of the pile body; an oil pipe, a displacement wire and a grouting pipe communicating with the pile body are arranged in the pile body, and the oil pipe, the displacement wire and the grouting pipe are led to the ground along the pile body; sediment at the pile tip is provided at the bottom of the pile body, a pressing plate is provided at the bottom of the sediment detection and treatment device at the pile tip, and a pile tip grouting body flows in the grouting pipe. This method for detecting and treating sediment at the pile tip solves the detection of the thickness of sediment at the pile tip after pile formation, which is of great significance to the reliability of the foundation pile. The sediment at the pile tip can be effectively treated through the reserved grouting pipe to ensure the effective exertion of the bearing capacity of the foundation pile.

[0004] When the prior art uses the method of pressure settlement to detect the thickness of sediment at the pile tip, it is often difficult to effectively extrude the sediment, which affects the accuracy and working efficiency of the detection. In practical applications, the detection results may not be accurate enough, unable to comprehensively reflect the true thickness and state of the sediment, thus restricting the effectiveness of subsequent treatment measures.

After the hydraulic oil enters the inside of the strip groove, it will push the driving plate to move. The movement of the driving plate will drive the sliding shaft to move, and the movement of the sliding shaft will drive the sliding plate to move. When the sliding plate moves, through the connecting shaft and the square block, it will push the pressing block to move synchronously.

[0013] Preferably, a sealing cover is connected to the top of the box body through a hinge.

[0016] By adopting the above technical solution, the guide pipe facilitates the sliding of the traction rope. After the grouting pipe is communicated with the concrete slurry delivery pump for delivering concrete slurry from the outside, when the delivery pump works to deliver the concrete slurry, the concrete slurry will flow into the flow groove through the grouting pipe, and then the concrete slurry will flow into the grouting component, and the pile tip sediment can be grouted through the grouting component.

The high-pressure oil pump works to transport hydraulic oil, and the oil pressure drives the driving component to move. The driving component adjusts the position of the pressing block. When the pressing block moves downward, it will exert pressure on the sediment at the pile end; S3. When detecting the sediment, the thickness of the sediment is detected by the detection component. If the sediment thickness is within the allowable range, there is no need to treat the sediment at the pile end.

When the connecting plate moves repeatedly, through the cooperation of the strip and the connecting block, it will push the knocking block to move repeatedly inside the square frame. Then, when the knocking block collides with the square frame, it will make the pressing block vibrate. When pressing the sediment at the pile end, it is convenient for the pressing block to move downward to squeeze and detect the sediment thickness, improving the detection efficiency.

[0027] 2. For the method for detecting and treating sediment at the pile end of the present invention, the arranged diversion groove and holes facilitate injecting concrete slurry into the sediment at the pile head for reinforcement, effectively avoiding the occurrence of construction accidents. When the square block moves to drive the pressing block to move downward to squeeze the sediment at the pile end, it will drive the diversion groove and the holes to move synchronously. When it is necessary to reinforce the sediment at the pile end, the transported concrete slurry flows into the flow groove, and then through the telescopic pipe, the concrete slurry flows into the diversion groove. Through the holes, the concrete slurry can flow into the sediment at the pile end, so as to reinforce the sediment at the pile end and avoid the loss of the bearing capacity of the pile body and the occurrence of safety accidents.

[0028] 3.

[0042] Working principle: Firstly, when using the pile-end sediment detection device, the frame 2 is preset at the bottom of the pile body 1. After assembling the concrete pile formwork, concrete is poured to prepare the pile body 1. The strip plate 3 and the plate 4 are fixedly installed on the top of the frame 2. When the pile body 1 solidifies, the frame 2 and the pile body 1 are fixedly connected through the plate 4 and the strip plate 3. After the pile body 1 solidifies and forms, when detecting the pile-end sediment, the top end of the oil injection pipe 14 is connected to an external high-pressure oil pump. The high-pressure oil pump works to transport hydraulic oil. The high-pressure oil pump works to transport hydraulic oil, and the hydraulic oil will flow into the inside of the strip groove 5 through the oil injection pipe 14. The edge of the driving plate 6 is surrounded by a sealing ring to seal the gap between the driving plate 6 and the strip groove 5. After the hydraulic oil enters the inside of the strip groove 5, it will push the driving plate 6 to move. The movement of the driving plate 6 will drive the sliding shaft 7 to move. The movement of the sliding shaft 7 will drive the sliding plate 10 to move. When the sliding plate 10 moves, through the connecting shaft 11 and the square block 13, it will push the pressing block 12 to move synchronously. Thus, the pressing block 12 will perform extrusion detection on the pile-end sediment. When the square block 13 moves downward, it will drive the driving block 33 to move. The driving block 33 contacts the square groove 43, and the driving block 33 will slide into the limiting block 32. When the driving block 33 slides, it will drive the connecting plate 34 to move. When the connecting plate 34 moves, it will drive the limiting rod 36 to move. The cooperation between the limiting groove 35 and the limiting rod 36 will make the connecting plate 34 move smoothly. When the pressure on the connecting plate 34 is no longer applied, the second spring 37 resets and will push the connecting plate 34 and the driving block 33 to reset. When the connecting plate 34 moves repeatedly, through the cooperation of the strip 38 and the connecting block 40, it will push the knocking block 41 to move repeatedly inside the square frame 39. Thus, when the knocking block 41 collides with the square frame 39, it will cause the pressing block 12 to vibrate. When pressing the pile-end sediment, it is convenient for the pressing block 12 to move downward to perform extrusion detection on the sediment thickness, improving the detection efficiency. When detecting the sediment, when the sliding plate 10 moves, it will drive the sliding block 21 to move through the traction rope 24. The sliding block 21 is guided by the guide rod 23 to move smoothly inside the sliding groove 20. When the sliding block 21 moves, it will drive the indicating block 22 to slide on the scale 19. Through the cooperation of the indicating block 22 and the scale 19, the settlement thickness of the pile-end sediment can be detected. If the sediment thickness is within the allowable range, there is no need to treat the pile-end sediment. When the pile-end sediment thickness is too thick and the pile-end sediment needs to be reinforced, after the transported concrete slurry flows into the flow groove 27, the concrete slurry flows into the diversion groove 29 through the telescopic pipe. The concrete slurry can flow to the inside of the pile-end sediment through the holes 30. Thus, the pile-end sediment can be reinforced to prevent the bearing capacity of the pile body 1 from being lost and avoid safety accidents.
