Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a prefabricated pile used for soft foundation treatment. Background Art

[0002] Soft foundation is composed of highly compressible soil layers such as silt, silty soil, and backfill soil. Due to the low bearing capacity of the soft foundation, it is easy to deform severely under load. In order to prevent accidents such as sinking and cracking of the soft foundation after construction, causing instability of the building, it is generally necessary to treat the soft foundation. During the construction process, prefabricated piles are usually driven into the soft foundation to improve the consolidation and stability of the soft foundation.

[0003] Precast piles are piles of various materials and forms (such as wooden piles, concrete square piles, prestressed concrete pipe piles, steel piles, etc.) made in factories or construction sites. The piles are driven, pressed or vibrated into the soil using pile driving equipment. They are characterized by being able to withstand large loads, being strong and durable, having a fast construction speed, and having a greater impact on the surrounding environment.

[0004] However, when pouring concrete inside the existing precast piles after welding and fixing, there will be air or bubbles inside the concrete during pouring, which will affect the reinforcement effect of the concrete. Therefore, it is necessary to exhaust the concrete inside the precast piles. The existing exhaust method is generally for operators to knock on the outer wall of the precast pile to cause vibration inside it to achieve the discharge of the internal air. However, this method is time-consuming and labor-intensive. Therefore, it is necessary to propose a precast pile for soft foundation treatment to solve the above problem. Utility Model Content

A plurality of support plates are connected and fixed around the outer wall of the support column and penetrate through the support column to the interior of the support column. A connecting column is installed on the top of the support column and penetrates through the interior of the support column and is fixed to the support plate. The top and bottom ends of the plurality of support plates are respectively connected and fixed with support rings and are located in the interior of the support column. The top end of the support ring is connected and fixed with a limiting ring and is slidably connected to the interior of the support column. The top end of the connecting column is connected to a turning handle, and the bottom end of the turning handle is connected and fixed with an L-shaped block and penetrates through the interior of the connecting column.

[0009] Preferably, a mounting groove matching the steel bar skeleton is formed at the top of the base, and a fixing groove matching the connecting ring is formed at the top of the base and the connecting ring.
