What's the use of piling on the construction site?

Piling reinforced the foundation of the building.

Because if the ground building is to be built on the ground, the ground must bear a lot of pressure, so it is often difficult to ensure that the ground has enough strength to resist pressure.

Therefore, it is necessary to reinforce the ground bearing buildings or improve the bearing mode of the ground. By piling on the foundation, most of the weight of the building can be transferred to the deep position below the ground through the pile, because the foundation at this position is much more capable than the ground.

Piling refers to the construction method of driving, pressing, vibrating or screwing piles of various materials into the foundation soil with special machinery.

Piling method:

1, hammering method

The impact energy of pile hammer is used to overcome the resistance of foundation soil to pile, and the pile is driven to a predetermined depth, which is suitable for soft plastic or plastic cohesive soil layer.

2. Vibration method

When piling, a high-power vibrating pile driver is installed at the top of the pile to reduce the resistance of foundation soil to the pile by vibration force. The piling efficiency in sandy soil is very high, and it can also be used for sinking and drawing steel sheet piles and steel pipe piles.

3. Water injection method

Using high-pressure water flow, the soil layer around the pile tip is loosened by the jet pipe installed at the side of the pile or in the hollow pile to reduce the pile driving resistance. Generally used in sandy soil, with high efficiency.

4. Pile pressing method

With the help of the self-weight of the pile frame and the weight on the pile frame, the pile is pressed into the soil through the reverse pulley. Pile pressing method can reduce the noise and vibration of foundation soil and adjacent buildings during hammering or vibration piling, and is suitable for relatively homogeneous soft soil foundation.
