[0002] High-pile wharf steel pipe piles are an important structural form in wharf construction. High-pile wharf steel pipe piles use large steel pipe piles driven into rock or deep soft soil as support beneath the water surface, thereby supporting the upper wharf and load.

[0003] Features of Steel Pipe Piles for High-Pile Wharfs: Strong Bearing Capacity: Steel pipe piles have a high bearing capacity, meeting the needs of large vessels and ultra-large container terminals. Wide Adaptability: Steel pipe piles can adapt to varying water levels, depths, and currents without changing their overall structure, depending on hydrological conditions. Convenient Construction: Steel pipe piles are relatively simple to manufacture and construct, and modular construction can be used to shorten construction time.

[0004] However, the cantilever ends of existing high-pile wharf steel pipe piles are too long, the pile tops shake too much, and they are in a high-frequency vibration state for a long time. Due to the long-term vibration of ordinary pile clamp welding, cracks will appear in the welds, which cannot meet the requirements of pile clamping. For steel pipe piles that need to withstand typhoons, ordinary I-beam welded pile clamps cannot withstand the wind and wave forces brought by typhoons. Therefore, a typhoon-resistant pile connecting device suitable for ultra-long cantilever piles is proposed to solve the above-mentioned problems. Utility Model Content

[0010] The stress relief structure includes a rubber block and a steel plate. There are two steel plates, and the two steel plates are fixedly installed on the left and right sides of the rubber block. The rubber block and the two steel plates are both provided with through holes, and the first connecting rod passes through the rubber block and the steel plates through the through holes.

[0011] Furthermore, the first connecting rod is provided with an external thread, the second connecting rod is hollow inside, and its left and right ends are connected, and the second connecting rod and the limiting sleeve are both provided with internal threads that are compatible with the external threads.

[0014] Furthermore, the left and right stress relief structures are respectively located between the left and right limiting structures.
