Introduction to soft base processing

Common methods and characteristics of soft foundation treatment：

1. Composite foundation method: 

cement soil mixing pile, powder spray pile, gravel pile, etc.; Disadvantages: high cost；

2, Drainage consolidation method：

(1) Combined drainage of prefabricated vertical drains: long construction period, unsatisfactory effect；
(2) Plastic drainage board combined with vacuum preloading: after 90 days of construction, the effect is easy to control and the cost is low；

3, Dynamic consolidation:

 shortcomings: quality is uncontrollable, easy to form "spring soil"；

4, No drainage sand cushion vacuum preloading: 

new construction method, short construction period, low cost, cost savings compared with plastic drainage board vacuum preloading one-third, the effect is reliable；

5, Explosion squeezed drainage method.
