HUNG GIANG Driving concrete piles

This method involves driving precast piles into the ground using a pile hammer. The primary construction equipment is the pile hammer (diesel hammer) mounted on the hanging frame of the base machine. Pile sections are lifted, attached to the pile hammer, and then lowered into the ground using the impact energy generated by the collision between the pile hammer and the pile head.

Driven Pile Construction

1. Types of Piles:

a. Square Reinforced Concrete Piles (BTCT):
- Dimensions 300x300;
- Dimensions 350x350;
- Dimensions 400x400;
- Dimensions 450x450;
- Dimensions 500x500;
- Dimensions 550x550;
- Dimensions 600x600;
b. Eccentrically Loaded Driven Round Piles
- D400; D500; D600; D700; D800; D900; D1000; D1100; D1200
c. Various Types of Steel Pipe Piles
These are common types of piles in contemporary construction. The length of each pile section varies based on design specifications.

2. Driven Pile Construction

This method involves driving precast piles into the ground using a pile hammer. The primary construction equipment is the pile hammer (diesel hammer) mounted on the hanging frame of the base machine. Pile sections are lifted, attached to the pile hammer, and then lowered into the ground using the impact energy generated by the collision between the pile hammer and the pile head.

3. Advantages and Disadvantages of Pile Driving Method

Advantages:
• The pile hammer construction equipment has a compact structure, operates independently, is easy to transport, and has simple operations. The machine is flexible and mobile, making it suitable for construction in various complex and challenging terrains.
• The pile driving method can be applied to square reinforced concrete piles, eccentrically loaded round piles, and steel pipe piles with dimensions ranging from D300 to D1000.
• Piles can be driven at an angle according to design requirements.
• Due to the high impact force of the hammer, this method is widely used in projects requiring the load-bearing capacity of large piles, such as bridge foundations, port bridges, and wind turbine foundations.
Disadvantages:
• One of the major drawbacks of this method is the production of loud noise, intense vibrations, which can affect surrounding existing structures.
