Description

Technical Field

[0001] This utility model relates to the field of construction technology of pile foundation engineering in civil engineering, and in particular to an emergency treatment device for plugging of bored piles. Background Technology

[0002] Drilled piles primarily provide stable support for building construction. They transfer building loads to deep, stable strata, effectively addressing adverse geological conditions such as soft soil and sandy soil, and preventing structural damage caused by foundation settlement. By adjusting the pile diameter and length, they can flexibly adapt to different load requirements, precisely control the amount and differential settlement of the building, and ensure structural safety.

[0003] Drilled piles utilize equipment such as rotary drilling rigs and impact drilling rigs to break up rock and soil to form holes. To prevent the hole wall from collapsing, mud slurry or steel casing is used for wall support. The mud slurry balances the lateral pressure of the hole wall and forms a mud cake, while the steel casing directly isolates the loose soil layer. After the hole is formed, the sediment is cleaned, a steel cage is lowered to enhance the strength of the pile, and then concrete is poured using the tremie method.

[0004] In existing technologies, during the construction of bored piles, the duct is easily blocked due to insufficient concrete fluidity and stone concentration. Dealing with the blockage is time-consuming and labor-intensive, which not only prolongs the construction period but also increases material and machinery costs. Therefore, an emergency treatment device for bored pile duct blockage is proposed to solve the above problems. Utility Model Content

[0014] As a further description of the above technical solution:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an emergency treatment device for plugging of bored piles, including a fixed sleeve 1, which provides a running trajectory for a telescopic cylinder 2. A motor 5 is fixedly connected to the inner wall of the fixed sleeve 1, and the motor 5 serves as a drive source to drive a threaded rod 10. The drive end of the motor 5 is fixedly connected to the threaded rod 10, which is used to drive the telescopic cylinder 2 and the threaded sleeve 13. Two fixing rings 11 are fixedly connected to the outer wall of the threaded rod 10, which are used to connect the fixed sleeve 1 and the threaded rod 10. The outer wall of the threaded rod 10 is threadedly connected to the telescopic cylinder 2, which provides a running trajectory for a telescopic cylinder 3. The outer wall of the threaded rod 10 is threadedly connected to the threaded sleeve 13, which is used to drive the telescopic cylinder 3.

[0033] The threaded sleeve 13 is externally threaded with a telescopic cylinder 2 3, which is used to drive the connecting plate 6. The inner wall of the telescopic cylinder 2 3 is fixedly connected with the connecting plate 6, which is used to drive the connecting rod 7. The inner wall of the connecting plate 6 is equipped with an installation component for easy installation. The outer wall of the telescopic cylinder 2 3 is fixedly connected with a limit block 4, which is used to prevent the telescopic cylinder 1 2 and the telescopic sleeve 2 3 from rotating. The outer wall of the limit block 4 is slidably connected to the inner wall of the telescopic cylinder 1 2. The inner wall of the fixed sleeve 1 is slidably connected to the outer wall of the telescopic cylinder 1 2. The inner wall of the telescopic cylinder 1 2 is slidably connected to the outer wall of the telescopic cylinder 2 3. The threaded sleeve 13 is internally fixedly connected with a limit ring 12, which is used to connect the telescopic cylinder 1 2 and the threaded sleeve 13. The outer wall of the limit ring 12 is rotatably connected to the inner wall of the telescopic cylinder 1 2. The two adjacent fixed rings 11 are fixedly connected to the inner wall of the fixed sleeve 1.

[0034] Reference Figures 2 to 4 The installation components include a control rod 9, which drives a latch 15. A connecting rod 7 is slidably connected to the outer wall of the control rod 9, which drives a drill bit 8. A latch 15 is fixedly connected to one end of the control rod 9, which connects the connecting plate 6 and the connecting rod 7. A spring 14 is fixedly connected to the inner wall of the latch 15, which resets the latch 15. The inner wall of the connecting plate 6 is slidably connected to the outer wall of the latch 15, and the outer wall of the latch 15 is slidably connected to the inner wall of the connecting rod 7. The outer wall of the connecting plate 6 is fixedly connected to one end of the connecting rod 7, and the other end of the connecting rod 7 is fixedly connected to a drill bit 8, which is used to clear the grouting pile. The outer wall of the telescopic cylinder 2 is fixedly connected to the outer wall of another limiting block 4, which restricts the movement of the telescopic cylinder 2 inside the fixed sleeve 1. The outer wall of the other limiting block 4 is slidably connected to the inner wall of the fixed sleeve 1.

[0035] Working principle: When it is necessary to dredge the cast-in-place pile, after the fixed sleeve 1 is put into the pile body, the motor 5 is started to drive the threaded rod 10 to rotate. The threaded rod 10 drives the telescopic cylinder 2 to slide axially through the threaded transmission. Since the limiting block 4 on the outside of the telescopic cylinder 2 is slidably connected to the inner wall of the fixed sleeve 1, its rotation is effectively restricted, ensuring that it only moves axially. At the same time, the threaded rod 10 synchronously drives the threaded sleeve 13 to rotate, and the sliding of the telescopic cylinder 2 pushes the threaded sleeve 13 to move axially through the limiting ring 12. With the help of the limiting block 4 between the telescopic cylinder 2 and the telescopic cylinder 3, the threaded sleeve 13 drives the telescopic cylinder 3 to extend and retract synchronously. This design can flexibly adjust the working length and effectively improve the coverage of the cast-in-place pile dredging operation.

[0036] When the drill bit 8 needs to be installed, pressing the control lever 9 causes the buckle 15 to compress the spring 14, installing the connecting rod 7 in the mounting position of the connecting plate 6. After releasing the control lever 9, the spring 14 returns to its original position, pushing the buckle 15 to precisely engage with the groove on the inner wall of the connecting plate 6. This design, through the linkage structure of the spring 14 and the buckle 15, achieves quick positioning and locking of the connecting rod 7 and the connecting plate 6. This quick installation design shortens the equipment installation time, significantly improves construction efficiency, and requires no additional tools, lowering the operating threshold and making it easy for on-site workers to get started quickly.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
