Research on the Technology of Full Cylinder Concrete Bite Pile of Deep Riprap Cofferdam

Abstract In order to solve the construction problem of deep ripped-rock cofferdam occluding pile under complex geological conditions, this paper studies the occluding pile engineering of Shenzhen-Zhongshan Link Construction pipe prefabrication yard as carrier. The research contents of this paper include the formation of occlusal pile, the reasonable combination of construction equipment, the optimization of concrete mix ratio, the treatment of isolated rock and the demolition of occlusal pile, etc., forming the key technology of the construction of cofferdam concrete occlusal pile under complex geological conditions at sea. Through the construction practice, the application of this technology has obtained a good effect of water sealing, and can provide reference for subsequent similar projects.
