Volle omhulsel -draaiboor is 'n nuwe, omgewingsvriendelike en doeltreffende boortegnologie. In onlangse jare word dit wyd gebruik in Urban Subway, Deep Foundation Pit -omheinde bytstapel, afvalstapel (ondergrondse hindernis) skoonmaak. Highspeed Railway, Road and Bridge, Urban Construction Pile Construction, Reservoir Dam-versterking en ander projekte.

The succesful research of this brand new process method has realized the possibilities for the construction workers to conduct the construction of casting piple, displacement pile, and underground continuous wall, as well as the possibilities for the pipe-jacking and shield tunnel to pass through the various pile foundations without barriers, when the obstructions, such as the gravel and boulder formation, cave formation, thick quicksand stratum, strong necking down formation and various Stapelbevestiging.

Die konstruksiemetode om Rotator te omhul, het die konstruksie -missies van meer as 5000 projekte op plekke van Singapoer, Japan, Hongkong -distrik, Sjanghai, Hangzhou, Beijing, Tianjin en Chengdu suksesvol voltooi. Dit sal beslis 'n groter rol speel in die toekomstige stedelike konstruksie en ander konstruksievelde van die stapelstigting.
