Abstract： During gravel pile construction of a power plant in Jiangsu province, considering that it is difficult to pour gravel in pile tube, the construction process of gravel pile is slightly improved to use air compressor to increase the air pressure in pile tube. Pouring difficulties are successfully solved and engineering construction is finished smoothly.

Key words： silty stratum vibrating immersed-tube gravel pile pore water pressure pressure balance method charging valve
