Description

TECHNICAL FIELD

[0002] At present, the requirements for the quality inspection of the pile forming of gravel piles in the specifications such as the Technical Code for Composite Foundation and the Technical Code for Building Foundation Treatment only require the use of dynamic penetration tests to detect the compactness and the integrity of the pile body.

In the process of gravel pile forming, the conditions of diameter expansion, diameter contraction and even pile breaking often occur. Diameter expansion causes material waste and cost increase, and diameter contraction and pile breaking will bring quality defects and safety hazards to the project.
