¡@¡nMethod Overview
 
  Method overview¡G
 

his invention targets mainly the big-bore foundation works, and for projects within cities and highly populated areas where space is limited and population has to be kept at its minimum.

 
  Advantages¡G
 
  1. Lower the cost to process and transport waste water and soil.

  2. Site can be cleaner and tidier.

  3. Space require to carry out this method is smaller.

  4. Better quality soil can be ensured for re-filling.

  5. Can be used for Squared cross-section piles, which provide better friction than circular cross-section ones.

  6. Very big bore(¡í>2M) constructions can be faster than RCD(Reverse circulation Drilling).
