Hammering method

The hammering method is currently a widely used pile-driving technique.

Land piling

Mast-type rack + hydraulic impact hammer (16t-20t);

Pile driving on water

Marine pile-driving vessel + guide rod hammer (or hydraulic impact hammer)

Construction Method Advantages

High penetrating power, capable of adapting to geological conditions with relatively high N-values (≤30 blows).

Suspension Impact Method

Applicable scenarios

The suspended impact method is suitable for construction near water bodies where the engineering geology is relatively hard and a construction interface is available.

Construction Method Advantages

It has strong penetrating power and can adapt to geological conditions with higher N-values (≤25 blows). It can be suspended for construction over a certain distance and is also suitable for construction interfaces where there are significant elevation differences on site.

Robotic Arm Vibration Method

Applicable scenarios

This method is generally suitable for shore-side construction involving piles with smaller specifications and shorter lengths (≤12m), in areas with relatively soft engineering geology, and where a certain construction interface is available. When the N-value is relatively high, mechanical pilot drilling can be used to assist in pile driving.
