UNDERWATER VIBRATING TYPE CONSTRUCTION DEVICE

摘要

PURPOSE:To improve a pile driving ability by eliminating the effects of the hydraulic pressure by providing the air reservoirs to a vibro device and forming the vapor phase sections. CONSTITUTION:The air reservoirs 6 & 7 for formation of the vapor phase sections are provided to one side of the vertical sides of a vibro device 5 having a mounting section 5a for transmission of the vibration driving force under the body. According to the constitution, a constrained force against the vibration of the vibro device 5 produced by compression and expansion of the vapor phase sections 6a & 7a is extremly reduced to have almost no effects of the hydraulic pressure, thus the pile driving ability is improved.
