[0031] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a pile foundation casing protection device, which is arranged on the opening at the top of the pile foundation casing 14 and covers the opening at the top of the pile foundation casing 14, and includes a connector 1, a support sleeve, and a support frame 2. The connector 1 is provided with a pouring port for concrete pouring. In this embodiment, the connector 1 is arranged at the center of the opening and is specifically in the shape of a circular ring. The inner diameter of the circular ring is adapted to the concrete pouring conduit, so that the concrete pouring conduit can be inserted into the circular ring and enter the pile foundation casing 14 for pouring. The support sleeve is arranged around the connector 1 and arranged radially along the opening. One end is connected to the connector 1, and the other end can be extended and retracted along the radial direction of the opening to engage with the outer wall of the pile foundation casing 14. The specific number of support sleeves is not limited. In this embodiment, four support sleeves are provided, evenly distributed around the circular ring-shaped connector 1, and are welded and fixed to the connector 1 to form a cross-shaped protection frame with a circular hole in the center. In order to avoid excessive gaps between the support sleeves, multiple support frames 2 are fixedly connected to the support sleeves to make the entire device more solid. There is no limit to the specific number, as long as the construction workers can stand safely.

[0032] Preferably, the support frame 2 is arc-shaped and arranged radially along the opening. In this embodiment, multiple arc-shaped support frames 2 of varying diameters are welded between the support sleeves and evenly distributed radially along the opening. The diameter of the outermost arc-shaped support frame 2 is smaller than that of the pile casing 14, allowing the entire support frame to be located within the pile casing 14. To enhance stability, multiple reinforcing ribs 3 are welded to the support frame 2, arranged radially along the opening. These ribs 3 are evenly distributed circumferentially along the connector 1.

[0033] Specifically, the support sleeve includes a fixed tube 4 and a movable tube 5. The fixed tube 4 is arranged radially along the opening, one end of which is connected to the connector 1, and the other end of which is sleeved with the movable tube 5. The movable tube 5 can move along the fixed tube 4, and the end of the movable tube 5 away from the connector 1 is engaged with the outer wall of the pile foundation casing 14. In this embodiment, the fixed tube 4 and the movable tube 5 are both configured as square hollow tubes. The fixed tube 4 is arranged radially along the opening, one end of which is welded to the connector 1, and the movable tube 5 is sleeved on the end of the fixed tube 4 away from the connector 1, with a clearance fit with the fixed tube 4, and can move along the fixed tube 4. The provision of the movable tube 5 allows the length of the support sleeve to be fine-tuned according to the diameter of the pile foundation casing 14, making it suitable for pile foundation casings 14 of different diameters.

[0034] Specifically, the end of the movable tube 5 away from the fixed tube 4 is provided with a bent end 6, which can be engaged with the outer wall of the pile foundation casing 14. In this embodiment, the end of the movable tube 5 away from the fixed tube 4 is welded with a 90° bent end 6, which can be abutted and engaged with the outer wall of the pile foundation casing 14.

[0035] Preferably, a positioning pin 7 is provided at one end of the fixed tube 4 on which the movable tube 5 is sheathed, for positioning the movable tube 5. In this embodiment, to prevent the entire device from sliding, a positioning pin 7 is provided at one end of the fixed tube 4 on which the movable tube 5 is sheathed. The positioning pin 7 is threadedly connected to the fixed tube 4, passes through the top of the fixed tube 4, and abuts against the movable tube 5. Tightening the positioning pin 7 secures the fixed tube 4 to the movable tube 5, thereby preventing the entire device from loosening and securing the pile foundation casing 14.

[0036] Preferably, a lifting member 8 is provided on the fixed tube 4, and the specific number and form are not limited. In this embodiment, in order to facilitate the installation and disassembly of the entire device, a lifting member 8 is welded on each fixed tube 4, and a wire rope or lifting chain can be connected to the lifting member 8 to lift the entire protective device.

[0037] Preferably, Figure 3As shown, the pouring port is covered with an opening and closing cover 9, one side of which is hinged to the connector 1, and the other side is engaged with the connector 1. In this embodiment, the opening and closing cover 9 is circular, adapted to the annular connector 1, and covers the top of the connector 1. One side of the opening and closing cover 9 is rotatably connected to the connector 1 through a hinge shaft 10, and can be opened and closed 180°. The other side of the opening and closing cover 9 is provided with a buckle 11 that is engaged with the other side of the connector 1. During normal protection, the opening and closing cover 9 is in a closed state. When concrete pouring is required for the pile foundation, the opening and closing cover 9 can be opened without moving the entire protective device.

[0038] Preferably, a warning light 15 is provided on the top of the opening and closing cover 9. In the present embodiment, the warning light 15 is specifically a flashing light, which is fixed in the middle of the opening and closing cover 9. By arranging the warning light 15, a warning effect can be played when the vision is limited at night.

[0039] Preferably, a crosshair 13 is provided on the top of the warning light 15, and the crosshair 13 is located at the center of the opening. In this embodiment, the warning light 15 is positioned at the center of the opening and closing cover 9. A transparent circular boss 12 is mounted on the warning light 15, and a crosshair 13 is engraved at the center of the top of the circular boss 12. The crosshair 13 is positioned exactly at the center of the pile casing 14, i.e., the center of the pile foundation. To detect the position of the pile foundation, the coordinate position of the center of the pile foundation hole can be measured by aligning a measuring prism or measuring instrument with the center point of the crosshair 13.

[0040] A construction method using the pile foundation casing protection device as described above comprises the following steps:

[0041] Determine the opening diameter of the pile foundation casing 14 to be protected. Based on this opening diameter, determine the lengths of the fixed tube 4 and the movable tube 5. Weld the lifting piece 8 to the fixed tube 4, and then weld the fixed tube 4 to the connector 1 to form a preliminary cross-shaped protective frame with a circular hole in the center. Weld the curved support frame 2 and reinforcing ribs 3 between the fixed tubes 4 to form a circular protective support frame that fits the pile foundation casing 14. This support frame can be placed inside the pile foundation casing 14, and the movable tube 5 and locating pins 7 can be installed. Install a warning light 15 on the top of the opening and closing cover 9, and a circular boss 12 with a cross mark 13 on the outside of the warning light 15. Then, install the opening and closing cover 9 on the connector 1.

[0042] Use a steel wire rope or lifting chain to connect the lifting parts 8, lift the entire protective device to the opening of the pile foundation casing 14 that needs to be protected, expand and contract the support sleeve according to the diameter of the pile foundation casing 14, adjust the relative position of the movable tube 5 and the fixed tube 4, and engage the support sleeve with the outer wall of the pile foundation casing 14 so that the entire support frame is located inside the pile foundation casing 14. Ensure that the length of each support sleeve is consistent and the cross mark is located at the center of the pile foundation casing 14. Tighten the positioning pin 7 to prevent the entire device from sliding, and fix the entire protective device at the opening of the pile foundation casing 14.

[0043] When construction workers need to measure the position of the pile foundation, they can directly measure the coordinate position of the center of the pile foundation hole by directly aligning the measuring prism or measuring instrument with the center point of the crosshairs 13. When it is necessary to pour concrete for the pile foundation, the opening and closing cover 9 can be opened and the concrete pouring pipe can be directly inserted into the pile foundation casing 14 to carry out the pouring operation without moving the entire protective device.

[0044] After the construction of the entire pile foundation is completed, the opening and closing cover 9 is closed, the positioning pin 7 is loosened, and the lifting part 8 is connected using a wire rope or a lifting chain. The entire protective device is lifted off the pile foundation casing 14 and placed in the storage position. The movable tube 5 is retracted into the fixed tube 4 and the positioning pin 7 is tightened to fix it.

[0045] The advantages and positive effects of the utility model are:

[0046] 1. The top opening of the pile casing is protected, providing safety for construction workers during operation. The protection effect is guaranteed by setting up multiple support frames.

[0047] 2. By setting up a retractable support sleeve, it can be applied to pile casings of different diameters. The support sleeve is connected to the pile casing by snapping, which is easy to assemble and disassemble, easy to operate, and recyclable;

[0048] 3. By setting up a warning light, it can serve as a warning, and can serve as a warning when the pile foundation is not completed and the vision is limited at night;

[0049] 4. The cross-mark setting is helpful for construction workers to measure the position of pile foundation;

[0050] 5. By setting up the opening and closing cover, it can not only play a protective role, but also can carry out pouring operations without moving the protective device, reducing the back and forth movement of the protective device, saving construction time and improving work efficiency.
