AI Technical Summary
During the splicing process of driven precast building piles, impurities such as soil and gravel can easily fall onto the pile tip, reducing the contact area between the pile tip and the bearing layer, thus affecting the pile's bearing capacity and stability. Existing protective measures are limited in effectiveness and complex to implement.
The lower and upper pile bodies are designed with special structures, including inserts, cones, annular grooves, clearance ring grooves, and lubricating coatings. Combined with a motor-driven rotating rod system, this ensures that impurities slide into the clearance ring grooves, avoiding interference with the connection and enhancing the contact area and connection stability between the pile end and the bearing layer.
It effectively prevents impurities from entering the pile end connection area, maintains the actual contact area between the pile end and the bearing layer, improves the pile's bearing capacity and construction efficiency, and simplifies the operation process.

TECHNICAL FIELD
[0001] The utility model belongs to the technical field of building engineering, specifically relates to a building pile for building engineering. BACKGROUND
[0002] In the field of modern building engineering, driven precast building pile foundation is widely used in various building projects due to its fast construction speed, reliable bearing capacity and other advantages. In the actual construction process of driven precast building pile, pile connection operation is a common and essential link. When the pile body is driven into the ground, the pile body has a significant extrusion effect on the surrounding soil. In the subsequent pile connection stage, this extrusion effect causes the soil around the pile to be in a relatively complex stress state, making it possible for the soil to enter the connecting part between the pile bodies and a small amount of soil to fall on the top of the lower pile.
[0003] For end-bearing piles, the effective contact between the pile end and the bearing stratum is the core element to ensure the bearing capacity of the pile. However, as in the above case, once the impurities such as mud and sand fall on the pile end, it will inevitably reduce the actual contact area between the pile end and the bearing stratum. This change directly leads to the pile end not being able to fully exert its due bearing effect, thereby significantly reducing the end bearing force of the pile. Although there are some conventional protective measures in the construction of driven precast building pile connection, most of them cannot effectively solve the problem of impurities entering the pile end caused by the extrusion of the soil around the pile. The existing protection methods have the disadvantages of limited protection effect, complex construction operation, high cost and other shortcomings, which cannot meet the strict requirements of modern building engineering on the quality and reliability of pile foundation.
