Application Analysis of Different Pile Types by Hengwang Pile Driver Manufacturer:

1. Bored Cast-in-Place Piles:

Application: Suitable for all buildings within industrial and civil construction, bridges, and hydraulic engineering.

Cost: 3 yuan per cubic meter.

Advantages: High single pile bearing capacity, strong adaptability to strata, and suitable for bearing layers with certain depth fluctuations.

Disadvantages: Side resistance softening of retaining walls, difficulty in removing sediments, relatively slow construction speed, and generally higher cost compared to cast-in-place piles and prestressed piles.

2. Manually Excavated Piles:

Application: Suitable for all buildings within industrial and civil construction and anti-slip piles.

Cost: 2 yuan per cubic meter.

Advantages: Guaranteed pile body quality and bearing layer strength, high single pile bearing capacity.

Disadvantages: Manual excavation, excavation depth generally does not exceed 25 meters, slightly poor construction safety, and higher cost.

3. Pipe-Sinking Cast-in-Place Piles:

Application: Suitable for buildings up to 10 stories within industrial and civil construction.

Cost: 6 yuan per cubic meter.

Advantages: Fast construction speed, low cost.

Disadvantages: Low single pile bearing capacity, strict construction quality control, and difficulty in penetrating upper and lower hard bearing layers.

4. Precast Reinforced Concrete Square Piles:

Application: Suitable for buildings up to 30 stories within industrial and civil construction, bridges, and other structures.

Cost: 4 yuan per cubic meter.

Advantages: High single pile bearing capacity due to on-site piling.

Disadvantages: Significant pile sinking and soil extrusion effects, quality issues in pile connections, not suitable for construction in old urban areas, difficulty in bearing heavy loads, and deviation in deep foundation excavation.

5. Steel Pipe Piles:

Application: Suitable for all buildings within industrial and civil construction, port engineering, and other structures.

Cost: 1 yuan per cubic meter.

Advantages: High single pile bearing capacity, fast construction speed.

Disadvantages: Highest cost and poor economic efficiency.

6. Cement Mixing Piles:

Application: Suitable for industrial plants, civil buildings, embankments, and structures up to 3 stories.

Cost: 1 yuan per cubic meter, with a cost index of 7.

Advantages: Good performance in water piling, suitable for flexible piles.

Disadvantages: Quality is difficult to control, prone to uneven mixing and significant settlement. The smaller the cost index per cubic meter, the higher the cost.
