Analysis on Common Construction Problems of Punching Pile in Flood Control Works
In order to explore the construction problems and treatment measures of punching pile in flood control project,the flood control project in Shaxi basin,Sanming city,Fujian province,is studied,and the ultrasonic transmission detection was conducted on some punch-in pile in this project.The results showed that the sound speed of HH0+518.39 and HH0+619.29 piles were 5.2 and 5.5km/s respectively,and the wave amplitude was 1 200and 1 180pV respectively,and the power spectral density of both did not change.It can be seen that both HH0+518.39 piles and HH0+619.29 piles have no defects and are class I piles.However,the sound velocity,wave amplitude and power spectral density of other piles are all changed in the corresponding positions,indicating that other piles have certain defects.
