During the vibration process, the cement slurry returns upwards, making it difficult to ensure the pile head's strength.

2. The main steel bars in the piles are used as reinforcement for the foundation platform.

3. Moreover, during the concrete pouring process, it is inevitable for the桩head (pile head) to fall into soil and other impurities. Therefore, the specifications require that the桩head elevation during concrete pile construction be 500mm higher than the design elevation. This portion of the pile head is manually removed to ensure the strength of the pile body.

4. Mitigate the impact of concrete necking due to lateral soil forces on the diameter of the pile.

Above is the introduction to why it's necessary to break the pile head. If you have any further questions, feel free to consult our website, where professionals will explain it to you.
