Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a soil counter-pressure device around a pile. Background Technology

[0002] Larssen sheet piles, also known as U-shaped sheet piles, are a new type of building material that plays an important role in projects such as bridge cofferdams, large pipeline laying, temporary ditch excavation as retaining walls, water barriers, and sand barriers; and in projects such as wharves, unloading yards as retaining walls, earth retaining walls, and dike protection.

[0003] Application No. 202322709760.7 discloses a pile perimeter soil counterpressure device, including a base located on the ground, a positioning pile integrally connected to the base extending into the ground, and a box fixedly installed on the base. The box contains extraction holes and cavities corresponding to the sheet piles, and guide rods, hydraulic cylinders, and sleeves are fixedly installed within the cavities. Symmetrically arranged sliders are movably sleeved on the guide rods. This invention uses the alignment of the extraction holes with the sheet piles, and the extension and retraction of the hydraulic cylinder output end causes the support rod to drive the pressure plate to press against the ground, ensuring the sheet piles can be extracted smoothly.
