Description

Technical Field

[0001] This utility model relates to the field of precast pipe pile construction technology, specifically a precast pipe pile splicing connection structure for pile foundation support. Background Technology

[0002] In modern construction engineering, pile foundation support is a crucial foundation component ensuring the stability of buildings, and its construction quality and efficiency are of paramount importance. Precast pipe piles, with their numerous advantages such as stable quality from factory production, relatively fast construction speed, and controllable costs, have been widely used in pile foundation support projects. However, in actual construction, due to factors such as site conditions and building design requirements, it is often necessary to splice precast pipe piles to meet different pile length requirements.

[0003] Currently, existing precast pipe pile splicing structures have significant limitations, including the inability to quickly assemble and disassemble them. Traditional welding connections, while ensuring a certain level of strength, are cumbersome. During construction, specialized welders must spend considerable time performing on-site welding, requiring not only high skill levels but also making the weld quality susceptible to environmental factors (such as humidity and wind). Poor welding quality can lead to safety hazards during subsequent use. Furthermore, separating the welded joints is extremely difficult when the pipe piles need to be removed or adjusted, typically requiring significant manpower and resources for cutting and other operations, severely impacting construction progress.

[0004] To address this issue, we propose a precast pipe pile splicing connection structure for pile foundation support. Utility Model Content

[0033] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0034] A preferred embodiment of the precast pipe pile splicing connection structure for pile foundation support provided by this utility model is, for example... Figures 1 to 7 As shown: A precast pipe pile splicing connection structure for pile foundation support, comprising:

[0035] The first precast pipe pile 1 is set longitudinally;

[0036] The second precast pipe pile 2 is arranged longitudinally, and the top surface of the second precast pipe pile 2 is in contact with the bottom surface of the first precast pipe pile 1.

[0037] Example 1: Figure 1 , Figure 2 and Figure 3 The second precast pipe pile 2 is connected to the first precast pipe pile 1 through the disassembly and assembly component 3.

[0038] Specifically, the disassembly / assembly component 3 includes:

[0039] The upper end of the L-shaped insertion rod 31 is fixedly installed to the outer wall of the first precast pipe pile 1;

[0040] The fixing block 32 is fixedly installed on the outer wall of the second precast pipe pile 2, and the socket 5 opened on the top surface of the fixing block 32 is inserted.

[0041] The arc-shaped locking rod 33 is engaged with the first arc-shaped opening 6 and the second arc-shaped opening 7 on the surface of the L-shaped insert rod 31 and the fixing block 32;

[0042] The arc-shaped plate 34 has an arc-shaped guide groove on its top surface, which slides with the arc-shaped locking rod 33.

[0043] In this embodiment, it should be noted that a first arc-shaped rubber pad 35 and a second arc-shaped rubber pad 36 are fixedly installed on both sides of the arc-shaped locking rod 33. The first arc-shaped rubber pad 35 and the second arc-shaped rubber pad 36 are both fixedly installed to the inner walls of the first arc-shaped opening 6 and the second arc-shaped opening 7. The clamping force can be enhanced by the first arc-shaped rubber pad 35 and the second arc-shaped rubber pad 36. The ends of the first arc-shaped rubber pad 35 and the second arc-shaped rubber pad 36 are rounded to facilitate the smooth insertion of the arc-shaped locking rod 33.

[0044] Furthermore, the arc length of the arc-shaped lever 33 is less than the arc length of the arc-shaped plate 34, which facilitates the sliding of the arc-shaped lever 33.

[0045] Example 2: Reference Figure 6 and Figure 7 A sealing assembly 4 is provided between the interior of the second precast pipe pile 2 and the first precast pipe pile 1.

[0046] Specifically, the sealing component 4 includes:

[0048] Hollow column 42 is fixedly installed on the bottom surface of circular plate 41;

[0049] The outer wall of the sealing cover 44 is fixedly installed with the inner wall of the second precast pipe pile 2, and the inner wall of the sealing cover 44 is snapped into the lower end of the hollow column 42.

[0050] In this embodiment, it should be noted that a sealing gasket 43 is fixedly installed on the inner wall of the sealing cover 44. The sealing gasket 43 is snapped into the hollow column 42. The sealing performance can be enhanced by the sealing gasket 43.

[0051] Working principle: When it is necessary to disassemble the first precast pipe pile 1 and the second precast pipe pile 2, the worker can first pull the arc-shaped clamp 33 to slide the arc-shaped clamp 33 along the arc-shaped groove in the arc plate 34 until the arc-shaped clamp 33 disengages from the first arc-shaped opening 6 and the second arc-shaped opening 7. Then, the first precast pipe pile 1 is pulled upward to completely disengage the L-shaped insert 31 from the insertion port 5 in the fixing block 32, thus completing the disassembly of the first precast pipe pile 1 and the second precast pipe pile 2, which is extremely convenient.
