Exploring the Relationship between the Bottom Rocks of the Pile and the Pile Hole Cleaning
At present, a lot of highway and railway development tend into use the bridge to replace of the road basis. It makes the construction of pile to be the core of the project. The hidden pile makes the construction to be more difficulty, but the technology of the ultrasonic texting improves the quality of the pile. Engineering practices have proved there has some closely relationship between the thickness of the end snaked grains and the pile supported strata stress.
