A precast pipe pile sealing device

Abstract

This utility model discloses a sealing device for precast pipe piles, including a sealing cover plate, a swing cover, and limiting components. The sealing cover plate is disposed on the top of the precast pipe pile; an opening is formed on the sealing cover plate. The swing cover includes a cover body and a rotating shaft; the outline of the cover body matches the opening; both ends of the rotating shaft are connected to the edge of the opening to straddle the opening. The swing cover rotates around the rotating shaft to close or open the opening. Limiting components are disposed on both sides of the rotating shaft to lock or unlock the rotation state of the swing cover. During construction, the closed swing cover dynamically seals the inner hole of the pipe pile, preventing soil and rocks from falling into the inner hole of the pipe pile; before core grouting, the limiting components can be released to open the swing cover, achieving non-destructive and rapid disassembly. The sealing device balances sealing reliability and construction convenience, and has the advantages of simple structure and high turnover efficiency.

Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction technology, and in particular to a precast pipe pile sealing device. Background Technology

[0002] During the construction of prestressed concrete pipe piles, the soil inside the pile hole is prone to collapse and fall into the hole, requiring a large amount of manpower to clean the hole before core grouting. Incomplete cleaning will affect the quality of concrete pouring. Traditional construction often uses temporary wooden boards or welded steel plates for sealing, but this has significant drawbacks: wooden boards need to be cut on-site and have poor sealing performance; although welded steel plates are strong, they are difficult to disassemble and require cutting and damaging the ends of the pipe pile, affecting the efficiency of subsequent core grouting. Therefore, there is an urgent need for a sealing device that can be quickly installed, reliably sealed, and disassembled without damage, to balance sealing reliability and construction convenience.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] like Figures 1-3 As shown, this utility model embodiment provides a precast pipe pile sealing device, including a sealing cover plate 1, a swing cover 2, and a limiting component.

[0027] The sealing cover plate 1 is a steel plate fixed to the top of the precast pipe pile 4. The outer contour of the sealing cover plate 1 matches the top shape of the precast pipe pile 4. The sealing cover plate 1 has a rectangular, circular, or elliptical opening 11. A pair of connecting grooves 12 are provided opposite to each other on the edge of the opening 11 for movably connecting the swing cover 2. Preferably, the pair of connecting grooves 12 are symmetrically arranged on the opening 11.

[0028] The swing cover 2 includes a cover body 21 and a rotating shaft 22. The outline of the cover body 21 matches the opening 11 on the sealing cover plate 1. The rotating shaft 22 is disposed on one axis of symmetry of the cover plate. The rotating shaft 22 spans the opening 11. In this embodiment, both ends of the rotating shaft 22 extend outward and are embedded in the connecting groove 12. The height of the connecting groove 12 is not less than the radius of the rotating shaft 22. As an equivalent alternative, in another embodiment, the rotating shaft 22 is fixed to the opening 11, and the cover body 21 is rotatably connected to the rotating shaft 22. The swing cover 2 rotates around the rotating shaft 22 to close or open the opening 11: when the swing cover 2 is coplanar with the sealing cover plate, the opening 11 is closed to prevent soil and rocks from falling into the inner hole of the precast pipe pile 4; when the swing cover 2 is inclined relative to the plane of the opening 11, the opening 11 is open to leave construction space. For ease of operation, a handle is also provided on the surface of the swing cover 2. In this embodiment, the handle is constructed as an arc-shaped wing ring 23. Preferably, the wing ring 23 is connected to both ends of the cover plate, and the corresponding central angle is not greater than 180°.

[0029] To prevent soil and rocks from falling into the precast pipe pile 4 through opening 11, the swing cover 2 needs to be fixed in the closed state to stably seal the opening 11. For this purpose, the device is equipped with a limiting component, which allows for quick manual locking or unlocking of the swing cover 2's rotation. The limiting component can take various forms. In this embodiment, the limiting component is a limiting rod 3. The limiting rod 3 is spot-welded to the sealing cover plate 1 and extends into the swing cover 2, subsequently unlocked by simple cutting. In other embodiments, the limiting component is a pin structure, where the pin is pushed into or pulled out of the swing cover 2 through axial insertion and extraction; the limiting component is a self-locking rotating clip located near the edge of the opening 11, which extends part of its structure into or out of the swing cover 2's range by rotating within the plane of the opening 11. It should be understood that the essential function of the limiting component is to restrict the rotation of the swing cover 2 relative to the sealing cover plate 1; therefore, it can also be fixed within the swing cover 2 to control its own structure extending into or out of the sealing cover plate 1. Based on this, the aforementioned spatial relationship of "extending in" or "exiting" can also be described as intersecting or separating from the boundary line of the sealing cover 1 and the swing cover 2. Preferably, in this embodiment, the limiting member is fixed only to one of the sealing cover 1 or the swing cover 2. Therefore, in order to restrict the rotation of the swing cover 2 in both directions, limiting members are provided on both sides of the rotating shaft 22. Since in this embodiment, the swing cover 2 can be completely removed for reuse, the limiting member is preferably fixed to the swing cover 2.

[0030] Before hoisting the precast pipe pile 4, the sealing cover plate 1 is fixed to the pile end, the swing cover 2 is closed, and the limiting device is locked. At this time, the swing cover 2 remains closed, effectively preventing external soil and rocks from falling into the inner hole of the precast pipe pile 4. When core grouting is required, the limiting device is unlocked, and the swing cover 2 can be flipped over by lifting it with the wing ring 23. In this embodiment, the device can be completely disassembled from the sealing cover plate 1 and reused for the next precast pipe pile.

[0031] In summary, the device achieves reliable sealing of the inner hole of the precast pipe pile 4 through rapid assembly, effectively preventing soil and rocks from falling in, significantly reducing the workload of subsequent hole cleaning, and improving the quality of pile formation. The limiting component can be quickly locked or unlocked, enabling convenient switching of the working state of the swing cover 2. The swing cover 2 also features a detachable structure, allowing for quick and easy removal for reuse. Furthermore, the device has a simple overall structure, uses widely available materials, is easy to process and produce, and requires minimal operator skills.

[0032] The above description is merely a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All technically equivalent modifications made based on the content of the present utility model specification shall fall within the protection scope of the present utility model.
