What's the difference between the snake piles and diaphragm wall and the concept of design of dieframe wall?

snake piles is the type of zigzag pile which are use in cohesion less soil which work on friction principle and diaphragm wall is constructed using a narrow trench excavated in ground and supported by an engineered fluid (typically a bentonite mud) until the mud is replaced by the permanent material. Generally diaphragm walls are made from reinforced concrete, though unreinforced walls can also be used. Walls generally range in thickness frommm tomm and can be excavated to depths ofm or more.
