Description

Technical Field

[0001] The utility model relates to the technical field of plain concrete pile construction, and more specifically to a plain concrete pile anti-deflection construction device for thick muddy soft soil layers. Background Art

[0002] Coastal areas are generally home to thick layers of soft soil, primarily composed of silt and muddy soil deposited in marine or terrestrial-marine transition phases. These soft soil layers exhibit "three highs and three lows": high water content, high compressibility, high sensitivity, low strength, low density, and low permeability. These characteristics result in low bearing capacity, poor engineering performance, and easy deformation under compression. Under vibration or loading, these layers can experience rheological and thixotropic effects, or the soft soil itself can consolidate, causing settlement and deformation of the site surface. Furthermore, these soft soil layers can affect foundation stability, bearing capacity, and pile quality. Piling is a common foundation treatment method in silty soft soil areas. This method is suitable for thick silt layers where large-scale deep treatment is difficult. Piling can be used to reinforce the foundation. In the early days, cement-soil mixing piles, sand-gravel piles, and wooden piles were commonly used. However, due to technical and equipment limitations, these methods have become less common. Precast reinforced concrete piles, in contrast, have gained widespread application due to their strong bearing capacity, low investment, guaranteed quality, and rapid construction.

[0003] However, during the driving of plain concrete precast piles, the soft soil makes it difficult to ensure the stability of the pile driver and the ability to exert impact force on the precast piles, resulting in poor results. It is also difficult to ensure that the precast piles always remain in a vertical state. Therefore, we have proposed a plain concrete pile anti-deflection construction device for deep silt soft soil layers. Utility Model Content
