Comparisonrelevant parameters of static pressure pile driver and geological conditions

Application scopeof geological conditions:

Specificto different geological conditions, we adopt different construction methods.For details, refer to "News Center-Industry News-Static Pressure PileDriver" in the website of the Company

Standardpenetration blow count (value N):

Determinationof number of standard penetration test N. The blow count that a 63.5KG hammerdrops freely at a height of 76cm and drives a standard penetrator into the testfoundation soil for 30cm, namely the number of standard penetration tests ofthis soil layer.

Application inpile foundation:

1.Determine the ultimate bearing capacity of a single pile;

2.Judge the possibility of pile sinking;

3.Determine applicable construction method
